The relatively new vice-chancellor at James Cook University in Townsville is a scientist-turned-to-business. Professor Sandra Harding reminds us that over one third of Australia is tropical and yet only one major university in this country, apart from Charles Darwin in the NT, is properly equipped to handle the range of topics so important to the north of our region. And, unlike some, they also have a successful campus in Singapore. TRANSCRIPT: Robyn Williams: Good evening, Robyn Williams with In Conversation, tonight coming from the north and here´s a question I sometimes lob to the unwary - how much of Australia do you think is tropical? Well the answer is 38% - a lot, and so all those considerations that apply to the tropics a different kind of medicine, lively weather, coral reefs with huge tourist connections, all this and much more needs to be handled with expertise at a university. And we have only two up there, Charles Darwin University in the Northern Territory and James Cook, both in Cairns and Townsville. Now James Cook University has a superb reputation as a centre for research and a relatively new Vice Chancellor, she´s Dr Sandra Harding, once of Brisbane and a scientist now in northern Queensland. Professor Harding when you came up here any surprises? Sandra Harding: It did surprise me, it was a very welcoming place, it surprised me particularly around the intensity of the relationships within the university and between the university and the region. Robyn Williams: So it´s actually connected to where it is both in Cairns and Townsville? Sandra Harding: It is connected and I think what was most interesting is that people within those broader communities are looking for more, they are looking for the university to play a major role in the social and economic development of the region. And that´s a role we are very happy to play. Robyn Williams: Now looking back at the history, is it 50 years ago that the first intention back in 1958 was manifest? Sandra Harding: It is, it was in the 50s when that occurred, a lot of local advocacy, vigorous argument about where the second university in Queensland should be and ultimately the Townsville community won the day. Robyn Williams: What were the choices then being mooted? Sandra Harding: I understand that it was looked to be put in Toowoomba actually, the second university in Queensland, but ultimately the Townsville community I think made the point quite appropriately in my view that Toowoomba was rather more accessible to Brisbane than Townsville could be. Robyn Williams: So when did the Cairns campus come to be? Sandra Harding: Oh that was in the 90s when we began to express our presence in the Cairns area in particular and the Cairns campus is going very well as well. Robyn Williams: So you´ve got those as well as a campus in Singapore. Now I think it´s perfectly well known that sadly the University of NSW which intended to open a campus there then pulled out. How did you come to be so successful? Sandra Harding: The university started in Singapore in 2003 and I think it started really quite quietly with very little fanfare, it was working with a partner and that partner was part of the Singapore government in order to very slowly build its presence and look to attract students certainly but also to do research on campus as well. The university chose very carefully the programs we gave there and the most popular program is psychology and it´s done very well. Robyn Williams: That´s a surprise, how come? Sandra Harding: Well I think it´s interesting, when you think it through where a lot of universities do business in IT in locations in south east Asia and indeed north Asia for that matter, when you think about it mental illness, mental health issues have not been recognised well in Asia more broadly. And so programs in that part of the world associated with psychology, there are relatively few of them, and this was a particular market need. So it´s been interesting for us that this has been incredibly popular. Robyn Williams: So you´ve got about a thousand students? Sandra Harding: We do have about a thousand students across the programs and we are moving to a new location because we´ve grown out of our existing location and we are shortly to move into a new campus. Robyn Williams: So are you just about the only Australian campus there or are there others? Sandra Harding: Other universities play a role in the Singapore education sector but they often do it through franchising arrangements and you´ve got a number of universities now that have been seriously looking at working in the same way that we are, or as close as they can I suppose, Curtin University, Newcastle University of course are working there with a partner too. So there is some that are trying to work into this market and into this Asian world city, it´s a fantastic place to be, but I think it´s fair to say that we are the only group doing research there. Robyn Williams: Now the interesting thing about James Cook University is that you´re smack in the middle of the tropics and 38% of the Australian land surface is tropical and so you´ve got this huge remit. What does that tropical association mean to you? Sandra Harding: This goes to the heart of what our university ought to be focusing upon. From the early 60s when the Universities Commission of Australia determined that the University College of Townsville would become a university in its own right they wrote on their report that this should become Australia´s National University for the Tropics. And while of course we were here to meet local labour market needs and to meet the needs of the northern Queensland community for education programs and research activity, I think it was with a lot of foresight that those early people who were involved in setting up the university could see the importance and the strategic nature of having a university in a developed country in Australia but looking at issues of relevance to the tropical world. So in that report it said that we should become Australia´s National University for the Tropics and I think that is exactly what we should be. And indeed, what we have done for a long time at the university now is determine to clearly and sharply focus on this going forward. Robyn Williams: How does that manifest in what sort of areas? Sandra Harding: For us there are a number of areas that we are looking to develop our interest in teaching and research and now across the spectrum. Of course as we are all aware the university is very well known for its marine and tropical biology, we will continue working in those areas of course. In addition tropical health and medicine is an area of growing importance and we have a medical school and we have a veterinary school. We have growth in our research profile there too but to my mind it also deals with matters of the environment, ecology, water also the humanities and social science. I think we mustn´t forget that at the end of the day a lot of the critical issues of the tropical world there are certain scientific issues but a lot of the science is relatively well known. What we need to do with here about people and communities and the way the tropical world is developing and I do believe that as a university located in a tropical land mass of a large developed country we should be playing a leadership role. Robyn Williams: Yes, because if you look at the map you´ve got practically the whole of Africa, you´ve got vast amounts of Asia, our neighbours as well as the Pacific. Now the Pacific might have small countries, well until you get to South America perhaps but you´ve got an awful lot of very interested people in the areas of anthropology, marine science you´ve mentioned, and making that connection is something that many of the other universities around Australia seem to have forgotten about sometimes. Sandra Harding: I think it´s very important that we do that and we do that in a context because of what this university is designed to do and its strategic intent is around a brighter future for life in the tropics worldwide. So for us, when you think about it, most of the critical issues facing the world today whether they are environment, ecology or health and medicine, whether it is about economic and social development, whether it´s about democratisation for goodness sake, many of those problems occur in its rawest form in the tropical world and to my mind our program and our research should be addressing those very issues. Robyn Williams: Yes, but what´s different say about your medical school which is quite new actually, is it in its training and its research quite different from the other medical schools in Australia? Sandra Harding: It is quite different, our medical school now has been around since the late 1990s, it´s an undergraduate program and it´s one where we focus on rural remote exposure. We focus on producing medical practitioners who certainly are fully aware of and up to date with modern technology and what you need to do in order to be a practitioner in the 2000s, but also are aware of how it is you operate in rural and remote locations with indigenous communities. And with communities that are basically under-served in many ways - so that´s a particular focus of our program and it´s one that has been very well received. Robyn Williams: And you´ve got a new hospital just down the road? Sandra Harding: Yes the Townsville hospital was relocated adjacent to our medical school which is a terrific thing. Of course the synergy is wonderful in terms of teaching and research as well. Robyn Williams: And Sandra Harding you trained yourself originally in science - what aspect? Sandra Harding: I did parasitology, I studied a parasite in sheep at the time, spent a day a week and much of the year on the killing floor of an export abattoir at Goulburn getting bits of parasites out of tissues - so that´s what I did initially. Robyn Williams: What aspect were you researching then? Sandra Harding: Oh, this was a relatively little known parasite, it was a relatively new one and we were really doing some very basic work on it, it was a parisone parasite and trying to better understand it and what its affects might be in meat. Robyn Williams: So how did you do a segue from that to business? Sandra Harding: Well a bit of a long story and to put it very briefly I thought very hard about whether or not I ought to be continuing on and do a PhD in that area. Had I done so it would have been around trapping feral cats because we thought that was the alternate host at the time. But I did take stock and I thought to myself I didn´t know if that was quite what I wanted to do and I´ve always enjoyed everything quite frankly, I enjoyed history, and sociology, and economics and maths and all of that. So I decided to give myself a bit of time out and decided to think again. So what I ended up doing was a Masters degree in a government related area, worked for a while, then ultimately went overseas to do a PhD on economic sociology. Robyn Williams: You didn´t miss the abattoir? Sandra Harding: I didn´t miss the abattoir for a moment and there are still hints of it when I´m cooking mince you know to make spaghetti bolognaise, it´s still there, there´s an echo there of the smell of the abattoir on a hot day. Robyn Williams: Yes, I can imagine. There´s something strange however about the ways in which business studies have changed institutions; I mean broadcasters, universities and so on. Do you have a view on the way that the new managerialism needs to be more connected to what you were saying before about how human beings really behave, about how communities behave so that you´ve got this tension between efficiency in a managerial sense and people and the flexibility they need to get on to be creative? Sandra Harding: Well I don´t see it as a tension quite frankly, to my mind if you think about it from the university´s perspective, as a university we are here to generate new knowledge, as a site of catalyst for innovation, we are here to generate human capital, we are here to be partners with advocates for various professional communities and indeed for our own community. Those are the things that we are here to do. However, in order that we do them we need to make sure that we are managing our organisation well so that we apply resources in the right areas so that we can in fact free our scientists up not to have to worry about those matters but so they can get on and do the science that we want them to do. So I don´t see it as intention, I actually see the business approach to these things is an enabler. Robyn Williams: In some places it isn´t. I remember in your old university QUT there was someone from the business school who did wonderful send-ups of some of the great clichés in management and the pillorying of that sort of ultra bureaucratic approach at QUT was well riveted. Sandra Harding: Well to my mind you can poke a lot of fun at it of course and there´s a lot of jargon and I think sometimes it´s easy for people to lose sight of what it is at heart that you´re trying to achieve. And to my mind as long as you´re mindful of managing in a responsible way, the financially accountable way but not losing sight of the heart of what the institution is all about. You know to do a bit of social ology for the moment, universities are institutions in a sociological sense and that means that it´s not good enough for universities simply to have a good bottom line, we are meant to be providing a benefit to society and that´s the basis of our esteem and that´s the basis on which we ought to be recognised I suppose and ultimately supported whether that´s through public funds or through private funds. So to my mind a university or an institution can´t lose sight of the heart of what it´s on about but that doesn´t mean to say you don´t have to be mindful of the business imperatives that are attached to meeting the needs of that heart. Robyn Williams: Now on the face of it, especially with a university if you like outside the major capital cities, you would expect it to be mainly an educational institution giving students degrees. But this campus is famous, world famous for its research - how did that come to be, this emphasis on research? Sandra Harding: I think that´s because of the birth of the university, initially it was set up as a university under that traditional model, to conduct research and certainly to undertake teaching learning programs as well but we were set up under the stewardship of the University of Queensland to become and indeed to be a university. I think a number of other regional institutions and this is no criticism of them have had a different history if you like and that has perhaps created different aspirations, but that different history often is associated with a theme teaching institution first of all and then looking to graft on research afterwards and I think some of them have really done it quite successfully. But our beginning our very core was around research activity and that is how it continues today. Robyn Williams: How will that be affected by the new kind of rationalism where some people have got to sacrifice traditions - well famously I think the departments of geology around Australia have been halved in their number over the last few years. Will you have to cut back in certain areas as well? Sandra Harding: Yes part of the challenge for us is as we know with funding that universities receive is that we do need to ensure that that funding base grows and universities have a responsibility there too, I mean we need to look for external sources of income from people who benefit from the work that we do. And in addition of course we are looking to the various reviews that are going on to potentially provide additional funding for us. At the moment most of our income that is discretionary income if you like to a certain extent comes of our teaching program. So the extent to which students don´t choose to study particular areas it becomes very difficult for us to offer those areas. You mention geology, earth sciences is an area that James Cook University is very well known for too and given that we are again at the centre of a resources and mining boom up here this is a very important area for us and I´m really pleased to say that we have a wonderful and very vibrant relationships and sponsorships from the major assets in the region such as BHP Biliton assets and there´s Strata and others as well which is terrific. So I´m feeling quite good about that particular area that you raise, I think what we need to do is ensure that we are working harder to make a case for the humanities and social science because we cannot be a university of the type that I want us to be unless we have vibrancy there too. So for us we have to think about our tropical ambition and think about then how that plays through into the humanities and social science. Robyn Williams: Yes, going back to geology I was at a major conference last week in Perth and they were just deploring the fact that they found it so damned difficult to get students despite the fact that there´s a boom, despite the fact that there were jobs all over the place and many of them terribly well paid. I mean it´s such a paradox isn´t it? Sandra Harding: It is a paradox and I think the IT industry would make the same argument, have the same lament perhaps. Part of the challenge for us here is to encourage students to make an active choice for some of these professions, not just because there´s money in it which there will be where there´s a labour shortage, but because it´s worthy and because it´s well worth while considering the a career in these areas. Unfortunately if you are waiting until the students are in Year 11 and 12 it´s just too late and in fact we are beginning to think we have to get to primary schools and indeed certainly the middle school years in order to encourage students to take the right subjects that are going to lead them through to the sciences in particular, science and technology in particular. We certainly have as all universities do various bridging programs to try and help students who want to make a different choice that they perhaps on the surface are ill prepared for so we try to assist those students but at the end of the day we´ve got to go back I think in educational years to really encourage students to think hard about careers in science and technology. Robyn Williams: Yes, what do you do to attract students to James Cook University from Australia, what do you really tell them about their prospects if you like in jobs or whatever, especially in tropical pursuits? Sandra Harding: We have of course a range of marketing platforms all universities do which encourage people to come here. I guess it is our flavour, so for students who are interested in issues associated with the tropical world whether they are biological sciences, physical sciences or social sciences I think that this of itself would be encouraging to students. We do try to ensure that students are aware that you can have a broad range of study in a really terrific location I must say too, but part of what we hang our hat on as well is we are a medium sized university, our classes are very small and it´s often interesting that students who transfer from larger metropolitan universities, and I had a conversation with one the other day and he said that they´d never met their head of school and wouldn´t even have a clue who that person is. When they had a bit of a drama about a piece of assessment they immediately were in touch with that person, that person personally helped them and there´s a friendliness and a personal touch if you like, a high touch here that perhaps isn´t always possible in the larger universities. So that´s part of the story too. Robyn Williams: And what about overseas, I´ve just done an interview with somebody from Brazil who is a young woman, brilliant of course, came here when she was 17 which is rather astonishing and is so committed that she is actually becoming an Australian citizen. I wonder how far afield your remit is for where a number of students come from - all over the world? Sandra Harding: They do come from all over the world but we are markedly different than any other Australian university in that the majority of our international students are coming from the United States, North America. Most universities of course the dominant student cohorts are from China, or India, or southeast Asia. In fact we need to do a little bit better there I think in order to add to some cultural richness of our campus, we certainly have people from all over the world coming from those countries too. But it is interesting that people choose to come here particularly from North America and South America as you found and a lot of those people of curse are interested in issues associated with the tropics and tropical science and tropical medicine. That´s what they are really very keen on doing and of course to come here where your location is your laboratory how wonderful is that and you´ve got a cattle property at Fletcher View, and we´ve got Orpheus Island a research station at Orpheus Island as well as campuses spread throughout the tropics. It´s a terrific place for international students to come. We don´t usually have to work too hard on international students, Europeans, a lot of Europeans are here too. Robyn Williams: What about members of faculty or lecturers and your professors, do you have to put a bomb under them to make them come here? Sandra Harding: Well again for those for whom this is location integral to their work no, not at all. People who understand the significance of the work that´s done here in those areas and so forth are very pleased to be here. To be fair though for some other people we have to encourage from within Australia in probably a much more focused way than people internationally because sometimes I guess folk from down south or from the west have a particular view of what northern Queensland might be like and almost without exception that view would be 20 years old or more. And therefore it doesn´t represent the sort of vibrancy I guess, the social and economic vibrancy that visitors to the region find these days. So we always do encourage people to come and have a look, we are always mindful of partners and to look after those people very well so they can make an informed judgement about joining us. Robyn Williams: Just two more questions - the first is when it comes to research maybe you´re not any longer in the abattoir but are you keeping your hand in some aspect of research in business or whatever? Sandra Harding: I do try to be, a few years ago I was involved in a very large Australian Research Council project called the Australian National Organisational Study which is on my website and we´ve done a second wave in the last year or so of this particular organisational survey and I´ve got fantastic colleagues in the University of North Carolina and Chapel Hill, NC State and UMAS Amherst with whom I work with in particular so they really do the work and they allow me to play - they are very kind a wonderful colleagues. Robyn Williams: Yes you keep a blog don´t you? Sandra Harding: Yes I do, I keep a blog and that can be accessed on the front page of the university. Robyn Williams: How interesting. And finally, what is the association of this James Cook University with the royal family in England? Sandra Harding: Well this is an interesting story. In 1970 James Cook University was signed into being by Queen Elizabeth II, she was here of course for the Bicentenary and the royal yacht Britannia as I understand was moored off Magnetic Island and on the appropriate day Prince Phillip and the Queen and Princess Anne came on campus and signed the university into being. Just recently I had the architect who was responsible for a number of the buildings at the time here, he´s in his 80s now, Jim Birrell and Jim was telling me do you know Sandra that there are only three universities in the English speaking world where a monarch has personally signed the university into being. And I said oh, tell me, and he said yes, Oxford, Cambridge and James Cook University. Robyn Williams: So there´s a special claim to fame, Professor Sandra Harding, Vice Chancellor of James Cook University in Townsville and her career from abattoir to business, from parasites to running a huge enterprise reminded me of another great Australia woman Dame Brigid Ogilvie recently elected a special fellow of the Australian Academy of Science. Once she was head of the immensely wealthy Wellcome Trust. Brigid Ogilvie: I was born in Glen Innes on a sheep farm, I was lucky enough to have a father who was a very unusual sheep farmer in that he believed in educating his daughters. I went to the University of New England where I did the course rural science, which the science is underlying animal production and I was, in fact, the first graduate. Came to England in 1960 as a PhD student and went to the School of Veterinary Medicine at the University of Cambridge where I did a PhD on the immune response to helminth parasites of the gut. Robyn Williams: What was it like for a young woman from country NSW in Cambridge then? Brigid Ogilvie: Well I had a very good time, I must say I had a particularly good time socially and I managed to do my PhD without too much difficulty. Robyn Williams: You didn´t play up much? Brigid Ogilvie: I played up a lot, I gave the college I was attached to hell, Girton College, I was not used to being treated as a mildly intellectually deficient 13 year old after my years at Armidale where I was in charge of a Hall of Residence which was theoretically female but in fact was bisexual. Robyn Williams: Do you know most young people when cast adrift like that, being told here´s a bench, here´s a problem, go and solve it and come back in three years would panic. Why didn´t you? Brigid Ogilvie: I think it was because growing up on a farm and being heavily involved in a farm I learnt to be responsible with the freedom that goes with life on a farm at a very early age. And I think my whole course of life has been related to that experience in my early childhood, I´ve always been very independent and done things my way. Robyn Williams: You´ve been with the Welcome Trust now for some years, how did you come to be from this practical person from the Australian bush who liked doing practical work in laboratories to being an administrator and a leader? Brigid Ogilvie: Yes many people found it very strange that somebody who was so enthusiastic about research should make such a career more at the time I did. I actually got restless after 17 years, 17 wonderful years at Mill Hill and the reason I got restless was I´d got to a point in my career where I got more fun out seeing the young people I was responsible for get turned on by scientific research than doing it myself. It´s the teacher in all of us I guess. Robyn Williams: Dame Brigid Ogilvie now living back in Australia some of the time. Well next week I shall be In Conversation with Julie Horsefield, another remarkable woman in science in NZ this time. Coming up on Catalyst in a couple of minutes on ABC TV the Eureka Prizes and I´ll take you on a tour of the Shine Dome at the Australian Academy of Science in Canberra.

Sandra Harding: Well a bit of a long story and to put it very briefly I thought very hard about whether or not I ought to be continuing on and do a PhD in that area. Had I done so it would have been around trapping feral cats because we thought that was the alternate host at the time. But I did take stock and I thought to myself I didn´t know if that was quite what I wanted to do and I´ve always enjoyed everything quite frankly, I enjoyed history, and sociology, and economics and maths and all of that. So I decided to give myself a bit of time out and decided to think again. So what I ended up doing was a Masters degree in a government related area, worked for a while, then ultimately went overseas to do a PhD on economic sociology. Robyn Williams: You didn´t miss the abattoir? Sandra Harding: I didn´t miss the abattoir for a moment and there are still hints of it when I´m cooking mince you know to make spaghetti bolognaise, it´s still there, there´s an echo there of the smell of the abattoir on a hot day. Robyn Williams: Yes, I can imagine. There´s something strange however about the ways in which business studies have changed institutions; I mean broadcasters, universities and so on. Do you have a view on the way that the new managerialism needs to be more connected to what you were saying before about how human beings really behave, about how communities behave so that you´ve got this tension between efficiency in a managerial sense and people and the flexibility they need to get on to be creative? Sandra Harding: Well I don´t see it as a tension quite frankly, to my mind if you think about it from the university´s perspective, as a university we are here to generate new knowledge, as a site of catalyst for innovation, we are here to generate human capital, we are here to be partners with advocates for various professional communities and indeed for our own community. Those are the things that we are here to do. However, in order that we do them we need to make sure that we are managing our organisation well so that we apply resources in the right areas so that we can in fact free our scientists up not to have to worry about those matters but so they can get on and do the science that we want them to do. So I don´t see it as intention, I actually see the business approach to these things is an enabler. Robyn Williams: In some places it isn´t. I remember in your old university QUT there was someone from the business school who did wonderful send-ups of some of the great clichés in management and the pillorying of that sort of ultra bureaucratic approach at QUT was well riveted. Sandra Harding: Well to my mind you can poke a lot of fun at it of course and there´s a lot of jargon and I think sometimes it´s easy for people to lose sight of what it is at heart that you´re trying to achieve. And to my mind as long as you´re mindful of managing in a responsible way, the financially accountable way but not losing sight of the heart of what the institution is all about. You know to do a bit of social ology for the moment, universities are institutions in a sociological sense and that means that it´s not good enough for universities simply to have a good bottom line, we are meant to be providing a benefit to society and that´s the basis of our esteem and that´s the basis on which we ought to be recognised I suppose and ultimately supported whether that´s through public funds or through private funds. So to my mind a university or an institution can´t lose sight of the heart of what it´s on about but that doesn´t mean to say you don´t have to be mindful of the business imperatives that are attached to meeting the needs of that heart. Robyn Williams: Now on the face of it, especially with a university if you like outside the major capital cities, you would expect it to be mainly an educational institution giving students degrees. But this campus is famous, world famous for its research - how did that come to be, this emphasis on research? Sandra Harding: I think that´s because of the birth of the university, initially it was set up as a university under that traditional model, to conduct research and certainly to undertake teaching learning programs as well but we were set up under the stewardship of the University of Queensland to become and indeed to be a university. I think a number of other regional institutions and this is no criticism of them have had a different history if you like and that has perhaps created different aspirations, but that different history often is associated with a theme teaching institution first of all and then looking to graft on research afterwards and I think some of them have really done it quite successfully. But our beginning our very core was around research activity and that is how it continues today. Robyn Williams: How will that be affected by the new kind of rationalism where some people have got to sacrifice traditions - well famously I think the departments of geology around Australia have been halved in their number over the last few years. Will you have to cut back in certain areas as well? Sandra Harding: Yes part of the challenge for us is as we know with funding that universities receive is that we do need to ensure that that funding base grows and universities have a responsibility there too, I mean we need to look for external sources of income from people who benefit from the work that we do. And in addition of course we are looking to the various reviews that are going on to potentially provide additional funding for us. At the moment most of our income that is discretionary income if you like to a certain extent comes of our teaching program. So the extent to which students don´t choose to study particular areas it becomes very difficult for us to offer those areas. You mention geology, earth sciences is an area that James Cook University is very well known for too and given that we are again at the centre of a resources and mining boom up here this is a very important area for us and I´m really pleased to say that we have a wonderful and very vibrant relationships and sponsorships from the major assets in the region such as BHP Biliton assets and there´s Strata and others as well which is terrific. So I´m feeling quite good about that particular area that you raise, I think what we need to do is ensure that we are working harder to make a case for the humanities and social science because we cannot be a university of the type that I want us to be unless we have vibrancy there too. So for us we have to think about our tropical ambition and think about then how that plays through into the humanities and social science. Robyn Williams: Yes, going back to geology I was at a major conference last week in Perth and they were just deploring the fact that they found it so damned difficult to get students despite the fact that there´s a boom, despite the fact that there were jobs all over the place and many of them terribly well paid. I mean it´s such a paradox isn´t it? Sandra Harding: It is a paradox and I think the IT industry would make the same argument, have the same lament perhaps. Part of the challenge for us here is to encourage students to make an active choice for some of these professions, not just because there´s money in it which there will be where there´s a labour shortage, but because it´s worthy and because it´s well worth while considering the a career in these areas. Unfortunately if you are waiting until the students are in Year 11 and 12 it´s just too late and in fact we are beginning to think we have to get to primary schools and indeed certainly the middle school years in order to encourage students to take the right subjects that are going to lead them through to the sciences in particular, science and technology in particular. We certainly have as all universities do various bridging programs to try and help students who want to make a different choice that they perhaps on the surface are ill prepared for so we try to assist those students but at the end of the day we´ve got to go back I think in educational years to really encourage students to think hard about careers in science and technology. Robyn Williams: Yes, what do you do to attract students to James Cook University from Australia, what do you really tell them about their prospects if you like in jobs or whatever, especially in tropical pursuits? Sandra Harding: We have of course a range of marketing platforms all universities do which encourage people to come here. I guess it is our flavour, so for students who are interested in issues associated with the tropical world whether they are biological sciences, physical sciences or social sciences I think that this of itself would be encouraging to students. We do try to ensure that students are aware that you can have a broad range of study in a really terrific location I must say too, but part of what we hang our hat on as well is we are a medium sized university, our classes are very small and it´s often interesting that students who transfer from larger metropolitan universities, and I had a conversation with one the other day and he said that they´d never met their head of school and wouldn´t even have a clue who that person is. When they had a bit of a drama about a piece of assessment they immediately were in touch with that person, that person personally helped them and there´s a friendliness and a personal touch if you like, a high touch here that perhaps isn´t always possible in the larger universities. So that´s part of the story too. Robyn Williams: And what about overseas, I´ve just done an interview with somebody from Brazil who is a young woman, brilliant of course, came here when she was 17 which is rather astonishing and is so committed that she is actually becoming an Australian citizen. I wonder how far afield your remit is for where a number of students come from - all over the world? Sandra Harding: They do come from all over the world but we are markedly different than any other Australian university in that the majority of our international students are coming from the United States, North America. Most universities of course the dominant student cohorts are from China, or India, or southeast Asia. In fact we need to do a little bit better there I think in order to add to some cultural richness of our campus, we certainly have people from all over the world coming from those countries too. But it is interesting that people choose to come here particularly from North America and South America as you found and a lot of those people of curse are interested in issues associated with the tropics and tropical science and tropical medicine. That´s what they are really very keen on doing and of course to come here where your location is your laboratory how wonderful is that and you´ve got a cattle property at Fletcher View, and we´ve got Orpheus Island a research station at Orpheus Island as well as campuses spread throughout the tropics. It´s a terrific place for international students to come. We don´t usually have to work too hard on international students, Europeans, a lot of Europeans are here too. Robyn Williams: What about members of faculty or lecturers and your professors, do you have to put a bomb under them to make them come here? Sandra Harding: Well again for those for whom this is location integral to their work no, not at all. People who understand the significance of the work that´s done here in those areas and so forth are very pleased to be here. To be fair though for some other people we have to encourage from within Australia in probably a much more focused way than people internationally because sometimes I guess folk from down south or from the west have a particular view of what northern Queensland might be like and almost without exception that view would be 20 years old or more. And therefore it doesn´t represent the sort of vibrancy I guess, the social and economic vibrancy that visitors to the region find these days. So we always do encourage people to come and have a look, we are always mindful of partners and to look after those people very well so they can make an informed judgement about joining us. Robyn Williams: Just two more questions - the first is when it comes to research maybe you´re not any longer in the abattoir but are you keeping your hand in some aspect of research in business or whatever? Sandra Harding: I do try to be, a few years ago I was involved in a very large Australian Research Council project called the Australian National Organisational Study which is on my website and we´ve done a second wave in the last year or so of this particular organisational survey and I´ve got fantastic colleagues in the University of North Carolina and Chapel Hill, NC State and UMAS Amherst with whom I work with in particular so they really do the work and they allow me to play - they are very kind a wonderful colleagues. Robyn Williams: Yes you keep a blog don´t you? Sandra Harding: Yes I do, I keep a blog and that can be accessed on the front page of the university. Robyn Williams: How interesting. And finally, what is the association of this James Cook University with the royal family in England? Sandra Harding: Well this is an interesting story. In 1970 James Cook University was signed into being by Queen Elizabeth II, she was here of course for the Bicentenary and the royal yacht Britannia as I understand was moored off Magnetic Island and on the appropriate day Prince Phillip and the Queen and Princess Anne came on campus and signed the university into being. Just recently I had the architect who was responsible for a number of the buildings at the time here, he´s in his 80s now, Jim Birrell and Jim was telling me do you know Sandra that there are only three universities in the English speaking world where a monarch has personally signed the university into being. And I said oh, tell me, and he said yes, Oxford, Cambridge and James Cook University. Robyn Williams: So there´s a special claim to fame, Professor Sandra Harding, Vice Chancellor of James Cook University in Townsville and her career from abattoir to business, from parasites to running a huge enterprise reminded me of another great Australia woman Dame Brigid Ogilvie recently elected a special fellow of the Australian Academy of Science. Once she was head of the immensely wealthy Wellcome Trust. Brigid Ogilvie: I was born in Glen Innes on a sheep farm, I was lucky enough to have a father who was a very unusual sheep farmer in that he believed in educating his daughters. I went to the University of New England where I did the course rural science, which the science is underlying animal production and I was, in fact, the first graduate. Came to England in 1960 as a PhD student and went to the School of Veterinary Medicine at the University of Cambridge where I did a PhD on the immune response to helminth parasites of the gut. Robyn Williams: What was it like for a young woman from country NSW in Cambridge then? Brigid Ogilvie: Well I had a very good time, I must say I had a particularly good time socially and I managed to do my PhD without too much difficulty. Robyn Williams: You didn´t play up much? Brigid Ogilvie: I played up a lot, I gave the college I was attached to hell, Girton College, I was not used to being treated as a mildly intellectually deficient 13 year old after my years at Armidale where I was in charge of a Hall of Residence which was theoretically female but in fact was bisexual. Robyn Williams: Do you know most young people when cast adrift like that, being told here´s a bench, here´s a problem, go and solve it and come back in three years would panic. Why didn´t you? Brigid Ogilvie: I think it was because growing up on a farm and being heavily involved in a farm I learnt to be responsible with the freedom that goes with life on a farm at a very early age. And I think my whole course of life has been related to that experience in my early childhood, I´ve always been very independent and done things my way. Robyn Williams: You´ve been with the Welcome Trust now for some years, how did you come to be from this practical person from the Australian bush who liked doing practical work in laboratories to being an administrator and a leader? Brigid Ogilvie: Yes many people found it very strange that somebody who was so enthusiastic about research should make such a career more at the time I did. I actually got restless after 17 years, 17 wonderful years at Mill Hill and the reason I got restless was I´d got to a point in my career where I got more fun out seeing the young people I was responsible for get turned on by scientific research than doing it myself. It´s the teacher in all of us I guess. Robyn Williams: Dame Brigid Ogilvie now living back in Australia some of the time. Well next week I shall be In Conversation with Julie Horsefield, another remarkable woman in science in NZ this time. Coming up on Catalyst in a couple of minutes on ABC TV the Eureka Prizes and I´ll take you on a tour of the Shine Dome at the Australian Academy of Science in Canberra.

Wed August 13 2008
In this polar year many initiatives are offering new insights into changes in Antarctica. Dr Phil Tucak from Perth has spent several months exploring sites where Weddell seals are found. His studies of their behaviour and biology at a time of change are both illuminating and exciting. TRANSCRIPT: Robyn Williams: Vaughan Williams, his Symphony Antarctica. Hello, Robyn Williams with In Conversation and you may have noticed that this year is Polar Year. It´s also the year of the frog, of the potato and quite a few other items as well but tonight we´re polar...despite the somewhat confusing discovery that polar year is two years long. Still, worth paying attention to these north and south elements of this planet of ours. Last week we heard a little about the Arctic. This time we go south, with a vet, to the ice. Dr Phil Tucak trained at Murdoch University in Perth and now treats the usual range of domestic animals in his practice. But he´s also an adventurous veterinarian; he´s also broadcast in a spell for local radio in Esperance Western Australia, and now he´s been venturing to Antarctica to look at the seals. Well Phil Tucak is with me in our Perth studios. Phil where did you go and how did you get there? Phil Tucak: During the summer of 2006/7 I had the opportunity to head down to Antarctica and heading down from Hobart south via Macquarie Island to the continent and it took us actually six weeks to get there because we had to travel and stop off at the various Antarctic stations to resupply them. So we stopped past Casey, tried to get into Mawson Station, got stuck in the ice for a week, and then eventually ended up at Davis Station where we got out. I suppose the first thing that perhaps strikes you about Antarctica is that it´s not what you expect all the time, it´s not just white and ice covered, there´s also rocky areas around the coast and so it´s quite different to that sort of initial imagining that you would have of the continent. But when you see it for the first time it's—on the horizon it is just incredible to know there´s this massive land mass down the southern end of the globe. Robyn Williams: One and a half times the size of the Australian continent. Yes, huge, and most people are just knocked out—were you? Phil Tucak: It is that thing—and I suppose also the fact that in terms of not just Australia´s involvement down there but various countries, obviously there are various stations down there but where they are located is obviously such a small area in terms of this overall size of the continent that you definitely do get the sense that you´re on your own down there. And even just travelling down there on the ship, the ship is an ice breaker to get through this ice, and down there but you´re well and truly on your own. So you have that sort of feeling that if something should go wrong you´re a long way from help. At the same time you´re comparing it to the earlier explorers and they were doing this similar trip in a tall ship, or that type of thing, it´s just amazing to think that they were able to get there and survive for the years or so that they were down there. Robyn Williams: A ship made of wood not so much size actually, they were quite small. Phil Tucak: Exactly and just the fact that they had to take enough food and how they survived for warmth—down there this time we were well rugged up, four of five layers of clothing, from your thermal underwear up to your fleeced lined jacket, beanie, gloves and it still gets cold. So to imagine what they must have been like back 100 years ago is pretty amazing. Robyn Williams: How did you get stuck in Mawson? Phil Tucak: Well we were there fairly early in the season. Generally what happens is that when the ships head down to Antarctica they are going during summer months when it´s a bit warmer, so the ice does break up. But we headed down in early October and when we got there the ice was still quite thick, so the ship tries to get as close as possible to allow the helicopters to fly off to resupply people to the station. And so we were trying to get as close—and I think the minimum distance they have for a fly-off was 80 kilometres or something like that and we just couldn´t get that close. So for quite a few days we were circling in the ice trying to get in different leads and then they figured they could just sort of sit there and wait, they had a bit of time to see if they could get a bit closer if the ice would break up. For about four or five days we were just sitting there, in the ice, the ship was still running but ice all around and you see an amazing amount of wildlife. The penguins come up to the ship and are obviously very surprised about this big orange hulk of a thing just sitting there. Whales surface through the cracks in the ice and it was a very sort of serene experience and at one point we wanted to get to Antarctica but at the same time it was very relaxing to have that opportunity just to sit there and drink in the vast expanse of Antarctica. Robyn Williams: What was a veterinary scientist doing in Antarctica, what was your role? Phil Tucak: I was involved in a field research study that was being conducted through the Australian Antarctic Division which is based in Hobart and also the University of Tasmania and they have their Antarctic Wildlife Research Unit and together they have been conducting various studies. But the one I was involved with was on Weddell seals and they are the most southerly ranging mammal that permanently inhabits the Antarctic mainland. And the good thing about Weddell seals is that they are very placid, laid backed, sedentary animals and that means that for a scientist we can actually get up close to them in order to be able to study them compared to people might have heard of things like a leopard seal, which is a bit more aggressive, has a lot more potential to give you some serious harm if you get too close. So Weddell seals are very laid back and as a result we can get near them, we can physically touch them, to measure them and so what we were doing was firstly we were doing a census of the number of these seals in a particular area called the Vestfold Hills region which is near Australia´s Davis Station and then subsequent to that we were then catching some of the adult females who had just recently pupped and had their young seal pups alongside and we were sedating and then measuring and weighing the adults to get an idea of their body condition and size and also their pups. And that way we could make a bit of translation between knowing how much condition had gone from the mum to the pup and then relate it back to how the season was in terms of whether they were having a good season or not. Robyn Williams: Just a thought on those leopard seals you talked about, a couple of weeks ago on The Science Show I mentioned two leopard seals who were in fact blown right through in a storm north to Australia and they were actually stranded off the coast of Sydney and then taken to Taronga Zoo. The point I was trying to make is in a discussion of how you keep the Antarctic separate I asked whether you could then take the leopard seals back when they recovered. And of course the answer was no, we don´t do that at all because they might have caught some sort of infection and Antarctica is so pristine we don´t want to bring new germs in. Now does that surprise you? Phil Tucak: No, I had heard that as well and actually had done a little bit of work at Taronga with one of the vets there who had been talking about this exact issue and in one sense it was frustrating for them because they knew that they had this magnificent animal that they had nursed back to health and that they couldn´t release it. But at the same time I can definitely understand the reasons for that, that as you mention, it´s to do with the fact that for a period of time if you have an animal who´s now associated in a different environment with humans and potentially coming into contact with maybe other animals or other animal germs as such, that the risk then if they then are released to go back to their normal population is that they could bring something into them. To relate it to what we were doing in terms of when we were going down to interact with the animals, firstly you have to have sort of permits to actually engage with these animals so it´s not just as if anybody can go there and do this. And most of the time staying away from them if we could in the sense of only touching them if we needed to and you´re sort of maintaining fairly good hygiene in doing that and the fact that the animals in their own environment are not getting stressed by the stuff that you´re doing. You are hopefully therefore minimising any potential risk to them of picking up any germs from you. But I suppose definitely it´s just one of those things that not only from the animal point of view but even getting on and off the ship we had to be careful of whether there was dirt, or seeds in our boots, or out clothing because you could quite easily transfer those types of things into the Antarctic environment and also out of—you don´t want to be taking things back onto the ship. So it´s just that whole area of hygiene and sort of making sure that we minimise our impact on them. Robyn Williams: It´s almost like going to a different planet and making sure you don´t seed it. Phil Tucak: That´s definitely right and it´s quite interesting to know there are other research studies going on where they are doing these things, where they´ve been studying the mount of seeds and spores which are carried in people´s clothing and it is quite scary to think what stuff could potentially be introduced down there to what is a pristine environment. Obviously there´s quite a few things down there which would probably stop most things growing because it´s very cold and not much would survive but I think it just brings into play that wider issue of Antarctica is a relatively untouched place and perhaps almost the last place on earth where humans haven´t had a bit impact on it as yet and hopefully it will stay that way. But it just means that we do have to be fairly careful if we are going to be involved down there. Robyn Williams: And the Weddell seals, they responded well to your intrusions? Phil Tucak: Surprisingly—I mean that´s the thing, even as a veterinarian you´re obviously always concerned about the welfare of the animal you are dealing with and in this situation, as I mentioned, they are a very sort of placid animal, so it means we could literally walk up to them and they would barely be bothered by us, they´d just sort of roll over, cock one eye at you as if to say who are you, what are you doing here. In terms of their response to the procedures we were doing, we were able to sedate them, weigh them, measure them, it was all over in about 15 minutes and as a result they were then sort of back with their pup, they were then quite happy to be just there lying on the ice again. So in terms of our interaction hopefully the information we were able to gain from dealing with them sort of outweighed any potential sort of small risk to the animal. And that information I suppose hopefully can be related back to things like climate change, effective fisheries in the ocean because if we can get just a small snapshot of what´s happening with the Weddell seals at their level of the eco system, the scientific research can then be correlated back to further down the food chain. And at a really simplistic level, if we have climate change occurring and sea temperatures are rising even slightly that affects the grown of algae on sea ice, which then affects how much food is available for the smallest of fish which are then eaten by bigger fish, which are then eaten by seals. So if we can sort of get a level at that point as to how they´re doing we can then relate it back and over a period of time work out what changes are occurring. Robyn Williams: The web of life. Any results yet? Phil Tucak: The results are sort of on going, it´s a research date that started in 2005 and is ongoing over several years. In terms of the population of Weddell seals in that area near the Davis Station it´s relatively stable which is great to know in terms of the numbers of actual seals. And the other data that they are collecting in terms of population dynamics so as to speak is also giving them data over a period of time to let them know what´s happening with that population. But also if they are attaching satellite monitoring tags to these seals, they are collecting specific information at the time to do with things like salinity levels in the ocean, where these seals are going, so they are definitely getting information that they can use right now and that´s going not only to the University of Tassie Antarctic Division but also the CSIRO who are also involved as well. Robyn Williams: Did you, Phil, have any veterinary work to do other than the scientific investigations; did you have to treat anything? Phil Tucak: No, many people would know that all the husky dogs have been removed from Antarctica for many years now, so there´s unfortunately none of them down there. Robyn Williams: It´s sad isn´t it? Phil Tucak: It is, but the good thing being that on the ship and at the bases as well there´s a lot of history associated with them still there, photographs and displays about life with the huskies. There´s wildlife around in terms of penguins and bird life and that but in general we don´t interact with these animals or don´t interfere in terms of if anything was going wrong. And I remember one situation where we were travelling through one of the ice covered fjords of this Vestfold Hills region and we came across a young seal pup which was right in the middle of the ice, no where near any of the adult seals or anything, so obviously it had been separated from its mum and was a long way from home and was not going to survive. But as to whether our role in that situation is to pick up this seal and move it and try and find its mum you would have a very hard time trying to do that. We don´t interfere, its how nature works down there and so as a result the veterinary work I was involved in is purely in terms of supporting this research team. Robyn Williams: You left it? Phil Tucak: We left the seal yes, it was a very hard decision to do and you hear so often of things where people are watching a lion stalk and attack an animal you know why didn´t they interfere or stop, it just gets back to the fact that this is nature in action and in most cases we are not in a position to be able to do any thing like for arguments sake, if we had picked up that seal and tried to find its mum, firstly that would have then imprinted us in it in terms of our scent, and also potentially stressed the animal out in the short term. And in trying to find its mum we wouldn´t have been able to know which one it was with so we probably wouldn´t have helped the situation at all. Robyn Williams: Yes, talking about imprinting, it may have thought that you were mum and followed you around. You´re responding as a scientist of course and you are surrounded by a number of other scientists, what general fields were they in the people who were on the team with you? Phil Tucak: The specific team that I was working with we were myself and three seal biologist so their background is all very strongly in the area of seal research. One of them actually was a former doctor who has now gone into the area of seal research and another one had been doing it for about 20 year, been down to Antarctica several times, so they had a great wealth of information between them in terms of the various research that they were doing. So it was great just to be involved with them and to learn a lot about the Weddell seals and also their other experiences in Antarctica. And then slightly broader to that we were also travelling down to Antarctica firstly on the ship there were about 90 to 100 expeditioners going down and that´s a combination of scientific staff but also the support staff for the base. So that´s tradespeople, a chef, doctor, management—you´re sort of exposed to a whole range of people and as a result you can learn a lot about all the different things that are going on. The other great thing about going to Antarctica is that everyone is really keen to help each other and there´s a lot of co-operation, so we were able to be involved in other scientific work that´s going on. I had the opportunity to head out with a moss scientist and collect moss samples which was something... Robyn Williams: It´s a surprising thing that moss grows in Antarctica actually. Phil Tucak: It is. Well that´s the thing, I´m sure it´s pretty much one of the only significant plant forms that do grow down there, the mosses and the lichens, and it is quite amazing because there´s so much just white down there in terms of the ice and the snow and the rock, a sort of browny colour. But if you see some of this green moss growing it is interesting for your mind to take that in because it´s such a strikingly different colour. So we had a few days we were out based in the field walking around and taking samples from different areas which they can then study and again I think moss itself holds a lot of clues to what´s happened over previous years, it´s a fairly long living plant form. So that was definitely interesting to be involved with but there is also geological work going on collecting ice core samples, there were people collecting water samples from beneath the lakes to see what marine life was down there, what was the sediment levels, people diving underneath the ice to again see what plants were growing in the seabed. So there was a whole lot of stuff going on and it is I great to know that there is so much science happening in Antarctica and that Australia is supporting that. Robyn Williams: Especially in this year when it´s Polar Year in fact which goes on paradoxically for more than a year, which is very interesting. With all those people there obviously there would be discussion, something to do with climate change. What were the general feelings amongst all your scientists about what´s happening down there? Phil Tucak: A common question I get asked a lot is could you see any effect of climate change there? And I think going down there once off, no you can´t, simply because you´re only there for a short period of time. Whereas some people had been there over progressive years and as a result they could make some comment as to subtle changes in terms of whether it´s the level of sea ice, when it forms, how thick it is, people who had been going back over several years could make more comments about that. It was also interesting the amount of marine life, whales around in terms of the whaling issue, there were different views about what was happening about that. But I think the thing being that people down there who were involved in research in science they are all so passionate and committed about finding the information that is stored in Antarctica and then being able to relate that to things like climate change so they can explain to people that there are changes occurring and we do need to consider the way we are doing things to hopefully slow down what is going on down there. But I think obviously climate change is something that is going to become more and more of an issue especially in Antarctica simply because a very subtle change in sea temperature has a lot more dramatic effects down there than it does perhaps up around Australia. Robyn Williams: Yes some people have said that the warming is going faster in the south but paradoxically because it might be getting warmer there would be more evaporation and therefore more precipitation, rainfall, snowfall and there´s very little of it. It is in fact, sometimes described as a desert because the rainfall, or the snow fall is so light. However, because of the increase in temperature paradoxically the ice may be getting thicker in places. Were you coming across that sort of argument while you were down there? Phil Tucak: No, but I can definitely understand that reasoning and I suppose it does just highlight that it´s a complex issue in a way and it´s going to take a lot of work for us to be able to try things and whether, even at the moment, there´s changes occurring in government in terms of carbon trading and all that sort of stuff which obviously has flow on effects, that it should for of help down there but I think the scientists have definitely been saying that changes in Antarctica have been accelerating, whether it´s in the recent decade or so in terms of various ice shelfs collapsing, it is telling us that there are changes occurring. And it would be very unfortunate or sad for us to lose such a pristine environment or for it to change, whether it means if you´re losing areas of ice covered water there´s therefore less areas for penguins or seals to breed, so therefore that effects their population. It does have a whole lot of flow on effects that we´re slowly becoming aware of. Robyn Williams: The other big issue that you mention—whales, you said there was much discussion were many people there amongst your colleagues for whaling? Phil Tucak: There were a few and I think it was perhaps specific to the species involved. One argument that was presented was that some of the species, I think it was maybe the minke whales, are sometimes referred to as the cockroaches of the sea and that there are a large number of them around the world. So therefore if we´re going to do whaling you´re not making a significant difference to their population. I´m not saying I agree with this, so that was one thing that I found interesting that some of the scientists were actually just voicing that in terms of the numbers—it´s not always the way it´s represented. But obviously at the same time there are species I think like the humpback or whatever which are in a lot more of a precarious state so therefore from a scientific point of view personally I would be very much against whaling. I think it´s one of those things where once you get down there and see the number of whales which are there it just sort of pushes home to you the fact that these are big and amazing creatures, the fact that they travel such vast distances, they are an important part of that eco system and in this day and age we perhaps don´t need to do whaling. As perhaps with many issues in science there´s always conflicting views whether something should be done or not and I think it´s one of those things where perhaps collectively we need to, even it´s more of an emotional response to something, say we don´t now need whaling whether it´s for oil, or the blubber, or whatever, we can get away without it so therefore let´s leave these animals to live in this pristine environment. Robyn Williams: Well Phil you came back, living in Perth, surrounded by city and normal life—was it a shock to return? Phil Tucak: It was, because when I came back it was the height of summer, I think it was about 40 degrees. So from Antarctica where we were generally around zero to minus 10, especially when the wind picks up you can get down to minus 20, so to come back to plus 40 degrees was a big shock and it did take me a while to adjust to that. I think also when you´re down there, we were down there, the trip was three months, and you´re surrounded by this group of people who are all very passionate and interested in what they are doing, it gets in your blood in that sense. So to come back and have to try to adapt back to normal life in the sense of the busy-ness of the city and what have you, it definitely was a shock. And I know that from speaking to other people that if you´ve been there longer, like some people go down for a year or so, the change is all the more dramatic and to be able to re-assimilate back into society can be difficult for some people. But I think the best part about it is you are able to hopefully bring back to people who haven´t been there a little bit about what it´s like, and it is a very hard thing to describe without going there. But hopefully in a small way you can get across a little bit of the magic of what it is to get to Antarctica. Robyn Williams: And what are you doing now? Phil Tucak: Working as a veterinarian in the city, so dealing mainly with dogs and cats and a little bit with horses. Still working in the animal field and hoping at one stage to get back to Antarctica somehow. Robyn Williams: More Vaughan Williams, his Symphony Antarctica. I was talking to Phil Tucak, back in Perth with his cats and dogs and budgies following his spell in the Antarctic helping us celebrate this Polar Year. Well next week we go to the other extremes, to the tropics, to talk to Professor Sandra Harding, the newish vice-chancellor at James Cook University in Townsville. She, like Phil Tucak, started with animals, in fact she spent quite a bit of her earlier scientific career looking for parasites and visiting abattoirs. But then she turned to business.

Wed August 06 2008
Australia could move entirely to renewable energy systems and transform our economy in ten years. It´s a bold idea but one that co-author of Climate Code Red, Philip Sutton, believes is doable and absolutely necessary. Alexandra de Blas is in conversation with Philip Sutton about how he thinks we can rescue our climate from its state of emergency...in a decade. TRANSCRIPT: Robyn Williams: Good evening. Robyn Williams with In Conversation. Well did you see Four Corners on Monday evening, a disturbing report about the vanishing arctic ice? Here´s a sample. 'As we left the sea ice of the high arctic at the end of our journey we had as many questions as answers. No one can predict the future of this unique place but the great sea ice is disappearing faster than all predictions. It will change the climate irrevocably not only are we partly to blame but we are continuing to push the arctic towards its tipping point.' Robyn Williams: From Marian Wilkinson´s report on Four Corners on ABC TV. So what to do? According to the book Climate Code Red, which has actually a forlorn-looking polar bear on its cover, there´s plenty of action we can take. The book, by Philip Sutton and Melbourne businessman David Spratt, is actually endorsed by the governor of Victoria Professor David de Kretser, himself a scientist, who actually launched the book at Parliament House. This evening we shall hear from Philip Sutton, director of Green Innovations, you may have heard him on Perspective after PM on Tuesday giving an outline of his concerns. Now a more extended conversation with Alexandra de Blas on the evidence and the responses. Philip Sutton: The most critical piece of evidence physically on the ground is the very rapid loss of ice from the Arctic which is now advancing so rapidly that it´s looking very likely that in summertime the ice will be completely lost within five years, possibly even within three years. Alexandra de Blas: Why is that such a problem? Philip Sutton: Because the Arctic ice is highly reflective, it sends out 80 to 90 per cent of the incoming solar radiation. If you then lose that ice the sea that is then exposed, the dark sea, is actually a very good absorber of energy and so it will actually capture a lot of solar energy and start to warm the Arctic dramatically, possibly causing a 5 degree warming locally which will then have significant knock-on effects in two critical areas. One is on the permafrost, which is the land area surrounding the Arctic Ocean which contains a vast amount of organic matter, old trees and vegetation of various sorts. And as that melts it starts to break down, and you get very large quantities of carbon dioxide, or methane, depending on whether the particular local environment is wet or dry. If it´s wet you´ll get methane, which is a very potent greenhouse gas; if it´s dry you will get carbon dioxide released directly into the atmosphere. Alexandra de Blas: So if this positive feedback loop happens what are the flow-on effects of that, and what sort of temperature rise are we likely to see globally? Philip Sutton: Our rough estimates are that the various knock-on effects, such as the permafrost and so on, could result in a two degree warming flowing out of the level of heating that we currently have. In other words you need very little additional pressure from the industrial system, from the human economy to get a two degree warming or even slightly higher from the heating that we´ve already created. Alexandra de Blas: When you say two degrees, what exactly do you mean? Is that two degrees above pre-industrial levels? Philip Sutton: Yes, it´s two degrees above pre-industrial, we are already one degree approximately, or 0.8 degrees above pre-industrial at the moment, so that this additional heating would produce just a bit over one degree. Alexandra de Blas: If we get up to two degrees in warming what sort of implications does that have around the world? Philip Sutton: People are familiar now with the story about increased extreme weather events and we´re having increasing difficulty getting crops to market etc, so that´s feeding in to our food crisis that´s emerging, even at this stage. It also feeds in to desertification around the world, so very large sections of arable land will be subject to drying. And the paradox is that in some places it´s not necessarily the case that the amount of rainfall will reduce, but that the air temperatures will be higher, the rain—when it comes—will tend to come in more intense bursts, more of it will run off and then the higher air temperatures will mean that the soil actually dries out more rapidly. So that the desertification or desert forming effect can occur while you even get increased total amount of rain in some areas. Alexandra de Blas: Why do you think the melting of the sea ice and the knock-on effects from that are catastrophic? Why is this an emergency, a climate code red? Philip Sutton: Well the permafrost can release almost the equivalent amount of carbon dioxide as we´ve released from all the fossil fuels around the world. One of the next kind of systems to fall over, which we think is close to one of these tipping points, is the Amazon forests, that´s another vast area where there´s a tremendous extent of forest and carbon in the soil as well. If the Amazon suffers from a drought that lasts for say seven years in a row—and they´ve had droughts up to five years so far—then that system can lose so many trees that it´s not able to maintain the normal water flow from the Andes across the continent, and that the Amazon itself, large slabs of it, can actually trip and change ecologically so they become dry grasslands. So you´d actually lose all the carbon stored in the vast Amazon rainforest, apart from that also being a massive loss of natural species, which would be terrible. Everywhere you look you find that there are these critical tipping points. So another one which is being pushed over at the moment is the Himalayan glaciers. China, India, Bangladesh, Indochina, Pakistan—all very, very seriously depend on the water flow coming out of the Himalayas through the snow melt. At the moment we are heading to lose pretty well all the Himalayan ice within the next few decades, so this is affecting literally billions of people´s livelihood and the ecological effects of course would be significant as well. So these are already underway, this is not something that we are talking about for some long distant future, these are threats that are posed by the current climate situation. Alexandra de Blas: Now the Greenland ice sheet, that´s another one of these areas with a tipping point and that could have up to seven metres in sea level rise. Where is that at? Philip Sutton: Greenland at the moment has now got extensive areas of melting each summer, it´s obviously melting rapidly around the edges but there´s also extended melt that extends over the surface of 50% of the area of Greenland. A lot of the scientists I think now believe that if the current temperature—we´re not talking about increases, but if the current temperature were to be maintained—that Greenland would just slowly melt until there´s a very small rump left. And I think people now feel that it has now actually entered that tipping point where it will be lost. The big question is how quickly will that occur and some years ago people thought that it might take 300 to 1,000 years to fully melt, as we see the melting occurring people are discovering that it´s a much more rapid process than they expected and so it´s quite possible now that you could lose a very substantial part of the Greenland ice sheet in 100 or 200 years. Alexandra de Blas: You´re saying that we´ve only got ten years, why do you say ten years? Philip Sutton: Well ten years is really more to do with the question of how fast we could be making the change. If you were to say well when did we pass the safe level, we probably passed the safe level 20 years ago, possibly even 30 years ago. So there is no further ten safe years, we´re actually in dangerous climate change now and it just simply goes from dangerous as it is now up to catastrophic over a period of time. Ten years is a period in which we could actually physically restructure the economy if we took the thing seriously as we need to. So for example the level of threat that´s implicit in climate change is at least equal, probably exceeds the threat that existed during the Second World War. During the Second World War, 1939 to 1945, economies around the world were restructured dramatically to create a world safe from the military incursion, we are now facing a threat which is equal or worse, and so we are saying with sufficient will and effort we probably could physically turn around the structure of the economy so it actually puts us on the path back to a safe climate. Alexandra de Blas: What proportion of GDP would it take to actually turn an economy around, to create a safe climate? Philip Sutton: Different people´s estimates vary, I´ve heard people say for 5% or 10% of the economy's turnover you could make that change. I´m not sure that that´s necessarily enough, because people are tending to look at what you are intending to do for the domestic economy and not taking account of the fact that the rich countries will probably have to play a major part in helping. If nothing else, helping with investments in the developing countries, China, India, Brazil etc, plus we´ve also got about 200 billion tonnes of excess carbon in the air already and we´re going to have to draw that out and that´s going to require big investments in the growth of vegetation of some variety, because it´s the best technique we have currently for sucking CO2 out of the air. That´s a big job, it could be a 30 to 100 year job and could require a lot of investment. Alexandra de Blas: Let´s actually go back to looking at what is a safe level of climate change, what are the levels that are dangerous? At the moment we have 387 parts per million of carbon dioxide in the atmosphere. Now you´re arguing that we have to bring that down to 320 parts per million, why do you think we have to bring it a lot further down that where it is today? Philip Sutton: It´s relatively simple, which is that we think we can´t have a safe climate without the Arctic sea ice in the summertime. The Arctic polar cap needs to be there. We then looked at when did it appear to be secure and that was at least as low as the temperature we had in 1980, we need to cool the planet by at least a third of a degree to be able to secure the Arctic sea ice. Alexandra de Blas: It seems interesting that some people are talking about warming of two degrees or warming of three degrees, because it´s not possible to bring the temperature down, but we wouldn´t tolerate that level of risk when it comes to insurance, or building an aeroplane, or building a bridge. What´s going on with the way we are looking at risk in terms of climate change? Philip Sutton: I think we are terrified more by the complexity of solving the problem than we are terrified by the impacts of the problem. We are really mesmerised by just how difficult it would be to shift a whole economy and the world economy in order to protect ourselves. A lot of people have said well it´s too hard therefore we´ll just simply have to look elsewhere for targets for the environment. Forgetting that there are consequences of taking these higher targets and these consequences are actually worse than the efforts that we´d have to put in to solve the problem. Alexandra de Blas: What do we have to do to bring the level of carbon in the atmosphere down? Philip Sutton: If we hook it on to reducing the temperature, so the question would be how do we cool the earth, there´s really three key components. The first one is that if we want to cool the earth then there´s no point in adding further heating agents to the atmosphere. We have to get the emissions down to zero. We also are likely to stay at about the temperature we are now if we simply stopped putting carbon dioxide out into the air and other greenhouse gases. Then the temperature would tend to stay roughly where it is now for several hundred years. Now that´s too hot for too long so we obviously have to then take carbon dioxide out of the air itself and that is most easily done by growing vegetation. And then the next question is how long will it take to get the excess carbon dioxide out of the air, because in terms of natural processes, until you get the carbon dioxide levels down you can´t really cool the planet properly. And so that´s where we´ve started to consider the serious prospect that as part of a total package of zero emissions and taking the CO2 out of the air, that you might also have to consider some level of direct cooling. Alexandra de Blas: You´re talking about fairly radical things there, are you talking about adding sulphur to the stratosphere? Philip Sutton: I guess the answer is yes, we are certainly looking at it. Or we need to increase the reflectivity of the earth and one way to do that naturally is to increase the amount of cloud formation. And any white surface, if you like, ice or cloud, will reflect a certain proportion of the incoming solar radiation back to space. Alexandra de Blas: How long do you think it´s going to take the world to become climate neutral if we turn around in the next ten years, how long before we see zero emissions? Philip Sutton: Given the capacity that we have, if we were able to mobilise with a level of intensity that we had during the Second World War then I have no doubt that we could get to zero emissions economy within ten years. Some work that´s been done in Victoria by the Beyond Zero Missions group, they´ve been looking at the idea of how to get to zero within ten years. And then just recently they developed a particular scenario where they believed that there are technical changes in the types of energy products, insulation, water heating technologies that we use, etc, that would enable us to actually have a 50% reduction in emissions within the space of three to four years once the program was actually initiated. Alexandra de Blas: You´ve written this book and you´ve started a network, but what are you going to do to create the awareness that this really is an emergency, that it is potentially catastrophic and we have to move immediately. People are starting to think that way, but how do you actually initiate a climate code red, like you initiate a code in a hospital? Philip Sutton: People need to get used to the idea that we need to declare an emergency, we need to think that this is an emergency and it´s the first step. One way to do that is to actually do it for yourself so you say okay, in my household, for my family, for our community or whatever, we think we are in a state of climate emergency, sustainability emergency. So you declare it locally and build it up so you might encourage your neighbours, encourage the local council to do it and then encourage the state government to do it and so gradually build it up from the grass roots. If people are used to thinking that way then I think it can happen. If you just sort of said well you know how are we going to get the world to suddenly declare a climate emergency, it´s not going to just suddenly happen at that big scale without a lot of build-up from within communities right around the world. We obviously need to work with people who are interested in Australia, need to work with people in every other country to ramp this up. One of the things I think people need to remember is that once people actually realise how serious the problems are, and this is a critical part of getting the change, then there is nobody who is in a sense on the other side. Whether you´re a coal industry executive or whoever you are, when you actually look at what´s going to happen to your children, or for that matter yourself in your older age if we don´t get this issue under control, then I think people will realise that we don´t have sides in this issue, we just simply have people who have woken up to the problem and people who haven´t. Alexandra de Blas: What are you going to do to influence government? Philip Sutton: In fact we wrote the book Climate Code Red, originally as a submission to the Garnaut Review, so we have made it available through the official processes and we now have a network of people working on this who are taking copies of the book to as many government officials and politicians and ministers in government as they can get access to. And we also feel that we need to work at both the top end of the hierarchy and the grass roots simultaneously. So one of the particular pieces of work we think is very important is to create a manual which shows you how you would actually implement a sustainability emergency so you can go to government and say look, here´s literally down to the fine detail how you can possibly do it so people can imagine it. And once you can imagine it then you can start to think about how to do it. Alexandra de Blas: How far are you down the track with that? Philip Sutton: We´ve sketched out some of the initial ideas in our book Climate Code Red, and we´re initiating a project at the moment to in fact produce the first draft if you like of that manual. Alexandra de Blas: How widespread do you think that will become? Philip Sutton: We put the first version of Climate Code Red up on the web as a PDF in February this year. We now have had people contact us from literally right around the world who are now campaigning using this tool. So we´re quite confident that already there are the beginnings of a movement that would in fact link people in all the major countries of the world. Alexandra de Blas: So what does this do that´s really different? Philip Sutton: I think we actually take the problem seriously and we say that we don´t want to simply have a less dramatic disaster than might otherwise occur, we want to have a safe climate and we're then rigorously going to try and work out exactly how you get that and what needs to be done. And every time we come across something that seems a bit harder or a bit difficult, if it´s necessary we just say well so be it, we´ll just have to work out how to make that hard thing happen. I´m reminded a bit of the experience of the effort during World War Two to produce the atom bomb, and the atom bomb itself was not a great blessing, but the process that they went through to produce it was interesting because when they started out they were concerned that the Germans would get the bomb and that would be devastating. They didn´t know how to produce a bomb, the science hadn´t been worked out, all they knew was that you could split an atom and they thought they could do it with uranium and they just discovered this new element called plutonium. And so that was about as much as they knew and within the space of three years they explored all the different avenues of science, they identified a range of different industrial processes that could be used to deliver the raw materials for the bomb, every time they found a method that looked as if it might be possible or relevant they would actually test it and run it to see how it would go. And that was the only way they could deal with all the uncertainties while also having to get a result within a very compressed time frame. So we just have to be experimental, we have to use as much foresight and forethought as we can to work on a system basis but then we also need to be highly adaptive as we actually go into the crises and as we start to try and create the solutions. Alexandra de Blas: If we are going to respond to this emergency what should happen to the coal industry? Philip Sutton: Well the coal industry basically is now an obsolete industry, I´m afraid, and I think we all need to come to terms with that. They are hoping that carbon sequestration might sort of save the day but the thing is if we continue to use more and more amounts of coal then the demand for sequestration sites and the infrastructure for that is going to take a long time to ramp up and it´s always going to be a problem of safety and so on. At this stage anyway it looks to me as if the simplest thing is to recognise that we need to move on from coal. Alexandra de Blas: What are the key elements that we need to change in order to become carbon neutral? Philip Sutton: The most effective thing to do is to stop using fossil fuels, so when it comes to energy supply for base load energy we need a combination of wind power, wind turbines on a very large scale, we need concentrating solar thermal introduced into the system, we need to put in energy storage so that you can even out the energy availability. We need to emphasise urban planning approaches which make it possible for people to get around with minimum use of cars—but that´s a long term process. In the short term we need to be looking at the use of fully electric motor vehicles and hybrids as another possibility. The electric vehicles open up the potential of using their batteries in the off time that they are sitting around doing nothing to actually be part of the energy storage for the renewable energy supply, so there´s a positive synergy there. We need to also look at the way we can take carbon dioxide out of the air and one of the most interesting ways that´s being examined at the moment is to grow vegetation and then heat it in an oxygen deprived environment and produce char and byproducts and you can produce synthetic oil and synthetic gas which could be used as part of the energy system. And then the black carbon char can be used as a supplement for agricultural soils which both improves the productivity of the soil but also gives us a way of getting that carbon out of the air and putting it underground in a safe way where it will be out of the way for thousands of years. Alexandra de Blas: If we are going to massively increase vegetation, don´t we run into all sorts of problems in terms of displacing areas of land that are currently used for food production? And we are seeing some of the consequences of growing vegetation for biofuels right now, which is partly leading to this increase in the cost of food around the planet. How realistic are these sorts of scenarios going to be? Philip Sutton: If all we did was just simply say well we´ve got to grow a whole lot more trees so we can produce char and put it underground, then that wouldn´t work. But firstly the char itself improves the productivity of the existing agricultural systems, so you´d actually get more food per hectare after you´ve treated the soil with the char than you would beforehand. But secondly we do need to look at the aggregate production of food and there´s some very interesting work that´s being done by a team in the Netherlands and they looked at how they could provide for production of high quality protein with much reduced environmental impact. They were using literally green houses as enclosed spaces for agricultural production to produce their food products and they were able to get massive increases in the productivity per hectare. Alexandra de Blas: Personally how optimistic do you feel? Philip Sutton: It´s a really interesting question, because if you sort of said well what are the odds of getting the right result out at the moment, in one sense you´d have to say that things look pretty grim. On the other hand I actually have a genuine optimism about the capacity of humans to solve problems if they can get around to doing it. And so my effort if you like is now of focusing more and more on how do we actually catalyse that change, because I actually think that we still have within our grasp the possibility of solving these problems substantially. There will be damage done but we´re already well into the problem so we´re not going to come out unscratched, unscathed, whatever. But I am actually optimistic and think we have the capacity to solve it if we decide to take on the job. Alexandra de Blas: And do you think we can bring our carbon levels down below where they are now? Philip Sutton: Physically absolutely—that´s the least of our problems. Alexandra de Blas: Well what´s the biggest of our problems? Philip Sutton: Deciding to take on the job and doing it. And that means not just thinking that we hope someone else will, it means that in a sense each one of us has to say well I´m going to take on this job and I´ll then work out what bit of it I can get some leverage on. Robyn Williams: Yes. Up to all of us. Philip Sutton, one of the authors of Climate Code Red. He was talking to Alexandra de Blas. And after that talk about the Arctic, next week we´re back down south in the Antarctic with Dr Phil Tucak, a vet from Perth who´s just returned from there where he worked on Weddell seals. At one point he was stranded on the boat off Mawson. Phil Tucak: Well we were there fairly early in the season and generally what happens is when the ships head down to Antarctica they are going during the summer months when mostly it´s a bit warmer so the ice does break up. But we headed down in early October and when we got there the ice was still quite thick so the ship tries to get as close as possible to allow the helicopters to fly off to resupply people to the station. And so we were trying to get as close and I think the minimum sort of distance they had for a fly off was 80 kilometres or something like that and we just couldn´t get that close. So for quite a few days we were circling in the ice trying to get in different leads and then they figured they could just sort of sit there and wait, they had a bit of time, to see if they could get a bit close if the ice would break up. So for about four or five days we were just sitting there in the ice with the ship still running but just ice all around and you see an amazing amount of wildlife, the penguins come up to the ship and obviously are very surprised about this big orange hulk of a thing just sitting there. Whales surface through the cracks in the ice and it was a very sort of serene experience and obviously at one point we wanted to get to Antarctica but at the same time it was very relaxing to have that opportunity just to sit there and drink in the vast expanse of Antarctica. Robyn Williams: Dr Phil Tucak from Perth, who´s also done some ABC Radio broadcasting in Esperance, in his time, his In Conversation with me next week. And on ABC TV right now, Don´t Die Young, always a good strategy. Production today by Nicky Phillips and Charlie McKune. I´m Robyn Williams. read less
Wed July 30 2008
The quiet hero of snoring therapy has just received a Clunies Ross Award, yet another recognition for physiologist Professor Colin Sullivan of Sydney University. His work began over thirty years ago and has led to a global, multibillion dollar industry based on masks directing airflows over the user's face. But is it true that apnoea, when people stop breathing as they snore, is behind most of today's vascular disease? And what next in this immensely important research? TRANSCRIPT: Robyn Williams: What a dreadful noise. Why do we do it? And how did humans survive out there in the forest, advertising their presence to all rampaging carnivores that they were there, asleep, ready to be devoured. Hello Robyn Williams with In Conversation. And today´s chat is about more than snoring. It´s about apnoea, those moments when breathing actually stops, damaging our physiology in the process. Henry VIII had apnoea, as did Churchill, Brahms, Rosie O´Donnell and Billy Connelly so I´m told by our producer, Nicky Phillips, and she should know. But for the last 30 years there´s been an effective treatment. The man behind it is Professor Colin Sullivan from the University of Sydney, and this was the turning point way back. Colin Sullivan: Well I remember it very clearly. The study was done in my laboratory, where I am still, at the University, and the patient was really very ill with the condition, he was 43 and he had severe sleep apnoea. I in fact recommended tracheotomy for him but the family refused outright. So he agreed to try this experimental method and in fact my first two PhD students who were involved with it; Dr Faiq Issa and Dr Michael Burton Jones. and we brought him in to the lab and set him up on a bed that I had set up there, or a bench, and put on the mask. In fact it wasn´t a mask, it was a pair of prongs attached to quite a large-bore tube, which I literally glued on with silastic material, which is a medical silastic, and we started recording, turned on the pressure and very quickly, like within minutes, he was asleep, we let him sleep with severe apnoea, repeated obstructions, his oxygen would go down to 50%, just turned up the pressure... Robyn Williams: The flow of air. Colin Sullivan: We turned up the flow because what it´s doing is increasing the pressure, so turned up the flow of air and then there was this absolutely normal trace and it was spectacular. The excitement was very hard to recreate, it was incredibly exciting so we waited and I decided well I´ll drop the pressure again, it could have been he´s gotten better spontaneously. We dropped the pressure—back came the apnoea, let it go for a few minutes, increased the pressure, stopped it again, decreased it—so we did this through several cycles. And I remember thinking well the next thing I need to know is if it´s going to work all night. So we decided to leave him on it all night. So we went through until about 6.30 in the morning and he slept for the rest of the night. I´ll never forget the look on his face when he woke up, because he was bright and alert and that day he was under my care in the hospital, he went back to the ward and he was awake all day for the first time. So it was a fantastic night and the physiology was very clear, it´s one of those, sort of, moments when you absolutely see what´s occurring. Robyn Williams: And you wrote a paper straight away? Colin Sullivan: That´s right and I sat down in my office while we were doing this and drafted the first draft of the paper. I was going to send off that paper but decided that it might be a one-off, I didn´t think it would be, but I would wait until I got several other patients. So we had four other patients and I trialled them first before sending off the paper. Robyn Williams: Professor Colin Sullivan. And that work has led to a huge industry, many prizes and membership of both scientific academies and, just now, a Clunies Ross award. But let´s go back to a time when our fathers snored like walruses, to a time of Franklin Delano Roosevelt, who also had apnoea by the way. Was there any treatment at all and did it matter? Colin Sullivan: Certainly not until the 1990s when I started working in the area, I remember the day, it was 1975, I was doing a PhD in physiology with Professor David Reid and our interests were how breathing was controlled. And he got me interested in the area because of an interest in the sudden infant death. However, I remember it was in November, another colleague of mine did the first sleep study on a patient and we became aware of sleep apnoea through that, through some literature that had been published several years before but it was still very unknown. So between that period and well into the 1980s people were not aware of the disorder, even though we´d become aware of it and no one was aware of just how extensive it was. Robyn Williams: And that question of snoring—and then when you stop breathing which is what apnoea is—was that thought to be just a normal process, that´s the way you slept at night? Colin Sullivan: Colin Sullivan: Absolutely, I think snoring at least was believed to be essentially normal, people had written, and talked, and joked about snoring forever, and because it´s so common people assume that it is normal. However, the stopping breathing, which again would have been and was reported, was thought—I would think that people would have seen their partners or father etc. doing that and thought it was part of ageing etc. So I think that´s probably one of the reasons why people didn´t take it seriously. I think the other reason is that because all of the events occur during sleep, certainly at that time in the 1970s the medical approach to sleep was the patients are all right and you can leave them alone. Robyn Williams: Well, look, this has puzzled me for a long time because if you go back further than 10,000 years, during 100,000 years when we were wandering around the plains or the forest—and it struck me about babies as well, if you´ve got screaming babies in the forest and you´re surrounded by sabre tooth tigers or whatever, you´re not going to last. Similarly if all the men are snoring around the campfire then you´re advertising your presence and it´s a risky business. Is it likely that snoring is a modern thing and we didn´t do it way back as primitives? Colin Sullivan: No I don´t, I think it´s occurred as part of the evolution if you like of our upper airway and it´s probably in part a consequence of our developing speech capacity—because the upper airways are actually a muscular tube which depends on muscle tone to stay open. So I don´t think it´s a modern phenomenon. Certainly there are references to snoring and obstruction in ancient literature, so I don´t think it´s recent at all. Some people in a semi-humorous way have suggested that snoring was protective, in the sense that if you´re in a cave and making this incredible noise it sounds more like a lion than a human. Robyn Williams: Keeps the beasts away. Colin Sullivan: Yes, that´s right. But no, I don´t think so. I think certainly in our time one of the major risk factors for developing snoring and obstruction is course obesity but it´s not the root cause. You have to have a small airway to begin with and it also involves the loss of muscle tone in sleep. But in modern times of course it´s part of the obesity epidemic that we are facing. Robyn Williams: Yes indeed, well of course with babies going around in ancient days meant that they did not cry as much, probably hardly at all, and I´d infer from what you said that slimline cave men or Neanderthals or whatever would tend to snore rather less. But bringing us to the modern day, lots and lots of men especially have snored a lot, and in the old days when you were first working, when the realisation came that it was a problem, the first sorts of treatment were surgical and fairly drastic, weren´t they? Colin Sullivan: Yes they were. The first treatment for obstructive apnoea was a tracheotomy, which was to make a hole in the windpipe and essentially bypass the upper airway. The first people to do that did it in the late 1960s, 1968; at that point it was thought to be a rare phenomenon a rare disorder. However during the 1970s a small number of centres started to identify patients and use tracheostomy to treat it. Robyn Williams: That´s pretty drastic. Colin Sullivan: It is drastic and in fact I went overseas to Canada where I worked on how sleep interacts with breathing—really driven by these new findings for us in the 1970s—but I returned to Sydney University and Prince Alfred in 1979 and my task then was to look after respiratory patients with respiratory failure. But I also began looking at people who had sleep apnoea. And we found really severe cases, few of them—in that first year I found two—but they were so bad we did do a tracheostomy and it was life-saving but it wasn´t a treatment you´d use for people who had less severe problems. Robyn Williams: No. Did they lose their voice in the process? Colin Sullivan: Yes, but what we would do was put a tracheostomy tube which also had a voice part, so they could just block the tube in the daytime, but it´s a drastic treatment. The other treatment that began to be used in the 1980s was surgical reduction of the pallet, so that the surgeon would go in and literally ream out parts of the upper airway in the throat region. Robyn Williams: The flap at the back. Colin Sullivan: That's right. And that was really introduced by a Japanese surgeon, first in Japan, and then he went to the US where they started to do it. And as this disorder started to be recognised, people thought well this is going to be the treatment—and of course it doesn´t work. Robyn Williams: It doesn´t work, I remember Norman Swan did a Health Report on the topic and showed in fact that it was a very mixed success if anything. Then you found there was a way of using what´s now called CPAP, a flow of air over the nose. How did that come about and how were dogs involved? Colin Sullivan: Well I remember very clearly my research in Canada involved working with sleeping dogs, and the person I went to work with, Elliot Philipson, had developed a model where he could study dogs´ breathing during sleep. In fact the dogs he had he made a tracheotomy so that these dogs had a hole in the front of their neck, which in fact was only used when he was doing the study, so it was allowed to just close up and when the dog ran around, it could still breath and eat. And what he would do was
