As a professor at Stony Brook University School of Medicine, I study how sleep is a mechanism through which policy and social factors can affect mental and physical health. I find that differences in sleep patterns across the population are contributing to disparities in health and wellbeing.  My current study of nearly 1000 teens from across the USA seeks to understand the contributing factors (including school start times and screen-based media) of insufficient sleep and health concerns among the young. In addition, I serve on the board of directors of the National Sleep Foundation, and I’m the founding editor-in-chief of the academic journal, Sleep Health, which, ironically, has cut into my own sleep health.

Out of the thousands of colleges and universities in the USA where I could have ended up, it is a fortuitous coincidence that, just across the road, my initial IIASA mentor Warren Sanderson teaches in the Economics Department also at Stony Brook University.  He still visits IIASA for three months every summer and continues to play a supportive role in my professional life.

I might never have pursued postgraduate work had it not been for my early experiences at IIASA. I had the unique opportunity to join IIASA for the Young Scientists Summer Program while still an undergraduate (long story). It was an incredible opportunity, as a college junior, to find myself within a week of my arrival in the summer of 1996, seated around a table with the world’s top demographers at an international workshop on world population projections. I credit Wolfgang Lutz for being so inclusive with the YSSPers. I found everything about systems dynamics and population modeling novel and exciting. For my summer project, I modeled the dynamics of tourism and fish populations off the coast of the Yucatan. Thankfully, I had enormous guidance and support from my mentor Warren Sanderson, and co-YSSPer Patricia Kandelaars. Patricia and I were both Aurelio Peccei scholars and invited back for a second summer, during which we pretended we were still in the YSSP program, joining for many heurigen evenings and other memorable weekend excursions.

Thanks to my positive experiences at IIASA, I entered a PhD program at Princeton University to pursue population studies, followed by a postdoctoral fellowship at the RAND Corporation, in Santa Monica, California. Although population sleep health research seems far afield from the interplay between fish and tourism in Mexico, I see a link to my experiences at IIASA, which is where I was introduced to systems thinking with policy relevance. Recently, I was honored to be invited to join the US National Member Organization for IIASA. Once again, I sought advice from Warren Sanderson, who encouraged me to accept the opportunity. I’m looking forward to giving back and reconnecting with IIASA.

Interview: Living in the age of adaptation

Adil Najam is the inaugural dean of the Pardee School of Global Studies at Boston University and former vice chancellor of Lahore University of Management Sciences, Pakistan. He talks to Science Communication Fellow Parul Tewari about his time as a participant of the IIASA Young Scientists Summer Program (YSSP) and the global challenge of adaptation to climate change.  

How has your experience as a YSSP fellow at IIASA impacted your career?
The most important thing my YSSP experience gave me was a real and deep appreciation for interdisciplinarity. The realization that the great challenges of our time lie at the intersection of multiple disciplines. And without a real respect for multiple disciplines we will simply not be able to act effectively on them.

Recently at the 40th anniversary of the YSSP program you spoke about ‘The age of adaptation’. Globally there is still a lot more focus on mitigation. Why is this?
Living in the “Age of Adaption” does not mean that mitigation is no longer important. It is as, and more, important than ever. But now, we also have to contend with adaptation. Adaptation, after all, is the failure of mitigation. We got to the age of adaptation because we failed to mitigate enough or in time. The less we mitigate now and in the future, the more we will have to adapt, possibly at levels where adaptation may no longer even be possible. Adaption is nearly always more difficult than mitigation; and will ultimately be far more expensive. And at some level it could become impossible.

How do you think can adaptation be brought into the mainstream in environmental/climate change discourse?
Climate discussions are primarily held in the language of carbon. However, adaptation requires us to think outside “carbon management.” The “currency” of adaptation is multivaried: its disease, its poverty, its food, its ecosystems, and maybe most importantly, its water. In fact, I have argued that water is to adaptation, what carbon is to mitigation.
To honestly think about adaptation we will have to confront the fact that adaptation is fundamentally about development. This is unfamiliar—and sometimes uncomfortable—territory for many climate analysts. I do not believe that there is any way that we can honestly deal with the issue of climate adaptation without putting development, especially including issues of climate justice, squarely at the center of the climate debate.

COP 22 (Conference of Parties) was termed as the “COP of Action” where “financing” was one of the critical aspects of both mitigation and adaptation. However, there has not been much progress. Why is this?
Unfortunately, the climate negotiation exercise has become routine. While there are occasional moments of excitement, such as at Paris, the general negotiation process has become entirely predictable, even boring. We come together every year to repeat the same arguments to the same people and then arrive at the same conclusions. We make the same promises each year, knowing that we have little or no intention of keeping them. Maybe I am being too cynical. But I am convinced that if there is to be any ‘action,’ it will come from outside the COPs. From citizen action. From business innovation. From municipalities. And most importantly from future generations who are now condemned to live with the consequences of our decision not to act in time.

What is your greatest fear for our planet, in the near future, if we remain as indecisive in the climate negotiations as we are today?
My biggest fear is that we will—or maybe already have—become parochial in our approach to this global challenge. That by choosing not to act in time or at the scale needed, we have condemned some of the poorest communities in the world—the already marginalized and vulnerable—to pay for the sins of our climatic excess. The fear used to be that those who have contributed the least to the problem will end up facing the worst climatic impacts. That, unfortunately, is now the reality.

What message would you like to give to the current generation of YSSPers?
Be bold in the questions you ask and the answers you seek. Never allow yourself—or anyone else—to rein in your intellectual ambition. Now is the time to think big. Because the challenges we face are gigantic.

What is driving Pakistan’s water crisis?

Firdos Khan Yousafzai, PhD student, University of Klagenfurt, Austria, and YSSP 2012 participant

In Pakistan, water supply fell from 5,260 cubic meters per capita in 1951 to 1,050 cubic meters per capita in 2010 according to the World Bank, and is likely to further fall in the future. According to the Falkenmark Water Stress Indicator, a country or a part of a country is said to experience “water stress” when the annual water supplies drop below 1,700 cubic meters per capita per year, and “water scarcity” if the annual water supplies drop below 1,000 cubic meters per capita per year. Water scarcity is especially critical for Pakistan because agriculture contributes 25% of the GDP and 36% of energy is obtained from hydropower.

In terms of geography, Pakistan is incredibly diverse, ranging from plain to desert, hills, forest, and plateaus from the Arabian Sea in the south and to the mountains of Karakorum in the north of the country. It has 796,096 square kilometers area—about the same size as Turkey–and approximately 200 million inhabitants.

Water availability is also different in different parts of the country. While various studies showed that climate change is happening all over Pakistan, research shows that the northern areas are more vulnerable. Possible reasons include the increasing population and deforestation, among others. Therefore, in my PhD work, which was also the subject of my work in the 2012 IIASA Young Scientists Summer Program, I am investigating that how fast climate is changing and exploring its impacts on availability of water.

In a recent study we investigated this issue under four different climate change scenarios, from 2006 to 2039 in the future. Different scenarios have different assumptions about population growth, use of energy type, environmental protection, economic development, technological changes, etc. We calculated the changes on the basis of baseline and future time periods for climate and hydrological projections. We found an increasing trend in maximum and minimum temperature, while precipitation is also changing under each scenario.

To assess water availability and investigate the impacts of changing climate on the operation of reservoirs, we used Tarbela Reservoir as a measurement tool, developing hydrological projections for the reservoir under each scenario. Tarbela Dam is one of the biggest dams in the world, and has a storage capacity of approximately 7 million acre feet and the potential to produce 3,400 megawatts of electricity.

In our study, we considered all the relevant parameters related to water shortages and surpluses. To compare the status of water availability, we compared the baseline period and future time period. The results show an increasing trend in water availability, however, water scarcity is observed during some months under each scenario. Further, we also observed that there is a 23-40% increase in river flow under the considered scenarios while the average increase is approximately 35% during the future time period.

As a conclusion we can say that enough water is available in Pakistan, and will continue to be available in the future. Instead, the study confirms previous reports that the major problem is mismanagement.

The possible solution may include constructing more dams and storage capacity to store extra water during high river flow which then can be utilized during low river flow. This could probably also be helpful in flood control, raise the groundwater level, and provide cheap and clean electricity to national electricity grid—providing multiple benefits, in view of the fact that the country has faced ongoing energy crises for many years.

Interview: A look back at the Young Scientists Summer Program

Former IIASA Director Roger Levien started the Young Scientists Summer Program (YSSP) in the summer of 1977. After 40 years the program remains one of the institute’s most successful initiatives.

The idea for the YSSP came out of your own experience as a summer student at The RAND Corporation during your graduate studies. How did that experience inspire you to start the YSSP?
At RAND I was introduced to systems analysis and to working with colleagues from many different disciplines: mathematics, computer science, foreign policy, and economics. After that summer, I changed from a Master’s in Operations Research to a PhD program in Applied Mathematics and moved from MIT to Harvard, because I knew that I needed a broad doctorate to be a RAND systems analyst.

From that point on, I carried the knowledge that a summer experience at a ripe time in one’s life, as one is choosing their post university career, can be life transforming. It certainly was for me.

Why did you think IIASA would be a good place for such a summer program?
When I thought about such a program within the context of IIASA, it seemed to me that it would offer an even richer experience than mine at RAND. I thought, wouldn’t it be wonderful to bring young scientists from many nations  together in their graduate-program years at IIASA. At that time, systems analysis was not well-known anywhere outside of the United States, and even there it was not very well known. In universities interdisciplinary research, and especially applied policy research, was almost nonexistent.

This would be an opportunity to introduce systems analysis to graduate students from around the world, who were otherwise deeply involved in a single discipline. It would be fruitful to bring them together to learn about the uses of scientific analysis to address policy issues, and about working  both across disciplines and across nationalities.

What was your vision for the program?
I hoped that these students, who had been introduced to systems analysis at IIASA, would become an international network of analysts sharing a common understanding of international policy problems. And in the future, at international negotiations on issues of public policy, sitting behind the diplomats around the table would be technical experts, many of whom had been graduate students at IIASA, having worked on the same issue in a non-political international and interdisciplinary setting. At IIASA they would have developed a common language, a common way of thought, and perhaps working together at the negotiation they could use their shared view to help their seniors achieve success.  A pipe dream perhaps, but also an ideal and a vision of what people from different countries and different disciplines who had studied the same problem with an international system analysis approach could accomplish.

The program is celebrating its 40th year. Why do you think it has been so successful?
I think there are many reasons for success. But for one thing, it’s my impression that just having 50 enthusiastic young scientists around brings an infusion of energy, which is a great boost to the institute. The young scientists also bring findings and methods on the cutting edges of their disciplines to IIASA.

What would be your advice to young scientists coming this summer for the 2017 program
It would be to engage as deeply as you can and as broadly as you can. This is an opportunity to learn about many things that aren’t on the curriculum of any university program. So, now’s the time to engage not only with other disciplines, but with people from other nations, to get their perspective. The people you meet this summer can be lifelong contacts. They  can be your friends for life, your colleagues for life, and the opportunities that will open through them, though unpredictable, are bound to be invaluable, both professionally and personally.

This is a learning experience of an entirely different type from the typical graduate program, which goes deeper and deeper into a single discipline. You have a unique opportunity to go broader and wider, culturally, intellectually, and internationally.

 IIASA will be celebrating the YSSP 40th Anniversary with an event for alumni on June 20-21, 2017.

Interview: An empirical view of resilience and sustainability

University of Tokyo researcher Ali Kharrazi credits the 2012 IIASA Young Scientists Summer Program (YSSP) with strengthening his passion, and giving him the research skills, to make a positive impact on humanity and sustainable development. He continues to collaborate with the institute as a guest researcher.

Ali Kharrazi

What is your research focus?
I’m currently examining both theoretical and empirical dimensions related to resilience and the wider application of sustainability indices and metrics. Towards this end, I have lately completed a literature review of empirical approaches to the concept of resilience, examined the resilience of global trade growth, and examined the resilience of water services within a river basin network.

My future project includes the examination of the application of modularity for resilience and its impact on other system characteristics of resilience, such as redundancy, diversity, and efficiency. In addition, I am collecting more data on the water-energy-food nexus, to empirically examine the resilience of these critical coupled human-environmental systems to various shocks and disruptions. I am working with other researchers towards channeling the emergence of urban big data towards practical research in sustainability indices and metrics, especially those which are related to resilience. Finally, I am engaged in what may be called ‘action research’ towards better teaching and engaging the concept of resilience to students.

How do you define resilience for a layperson or a student?
At its simplest, resilience is the ability of a system to survive and adapt in the wake of a disturbance.

The concept of resilience has been dealt by various disciplines: psychology, engineering, ecology, and network sciences. The literature on resilience relevant to coupled social-environmental systems therefore is very scattered,  not approached quantitatively, and difficult to rely upon towards evidence based policy making. There are few empirical approaches to the concept of resilience. This makes it difficult to measure, quantify, communicate, and apply the concept to sustainability challenges.

What is missing from current approaches of studying resilience?
There is a need for more empirical advancements on the concept of resilience. Furthermore, empirical approaches need to be tested with real data and improved for their ability to measure and apply in policymaking. If you look at the Sustainable Development Goals (SDGs) the concept of resilience is used numerous times, however the indicators used to reflect the concept need to be improved to better reflect the elements of the concept of resilience. This includes the ability to consider adaptation, the ability to integrate social and environmental dimensions, and the ability to evaluate systems-level trade-offs.

We need to apply the different empirical approaches to the concept of resilience towards real-world sustainability challenges. With the emergence of big data, especially urban big data, we can better apply and improve these models.

How did you personally become interested in this field of research?
I always wanted to make a positive impact for humanity and our common interest in sustainable development. When I first started my PhD, my PhD supervisor at Tokyo University, Dr. Masaru Yarime, told me to always set your sight on the ‘vast blue ocean’ and how as researchers we should dedicate our time to  critically important yet less researched areas. Given the global discussions of SDGs and the Agenda 2020 at that time I became interested in the concept of resilience, its relationship to common sustainability challenges, and our inability to measure and quantify this importance concept. My research stay at IIASA and YSSP and especially my experience with the ASA group strengthened my passion to contribute to this area and therefore since my PhD I have continued to research in this area and apply it to various domains, such as energy, water, and trade.

How would you say IIASA has influenced your career?
Without IIASA and especially the YSSP in the Advanced Systems Analysis program, my academic career would have never taken off. I am truly indebted to the YSSP, where I learned how to engage in scientific research with others from diverse academic and cultural backgrounds and most importantly had the chance to publish high quality research papers. IIASA also gave me the chance to get experience in applying for international competitive funding schemes and truly believe in the importance of science diplomacy and influence of science on global governance of common human-environmental problems in our modern world.

Making the most of the IIASA Young Scientists Summer Program

By Muenire Koeseoglu, Young Scientists Summer Program alumnus.

In the summer of 2016 I traveled to Austria to take part in the IIASA Young Scientists Summer Program (YSSP). Being part of this intense experience, not only in terms of scientific research but also in a social and networking sense, was very rewarding. I learnt a lot, travelled a bit, and made many new international friends and valuable connections for life. However, if you are thinking about applying to the YSSP, some prior preparation and an open mind are essential to absorb what the environment offers.

My YSSP project examined water pollution issues in Scotland, looking into a trading framework that would help address diffuse pollution. My advice to any potential YSSPer working on applied topics like myself is to identify their research question in broad terms with room for possible change. Understand the policy landscape around the issue to establish the policy relevance, and possible partners in the field who might be willing collaborate as a part of their preparation before arriving to IIASA. Establishing connections might be time-consuming, and people might not necessarily be interested in taking the time to help a postgrad student or in sharing information or data which might be confidential, yet even a few successful attempts will be useful in terms of getting site-specific information, data, and feedback. It will also save you time during the YSSP and potentially help clarify the real-life problems beyond the literature or directives. For instance, my initial proposal for the YSSP was to design a trading scheme based on water allowances among different water users at catchment level. However, after relevant consultations, I realized that designing a scheme that would enable trading permits to pollute rather to take water would be more applicable to Britain and especially Scotland, where diffuse pollution impacts affects many more catchments than do water shortages.

From my perspective there were many things that made my YSSP a special experience but the most important factor has been the people, my YSSP peers, the IIASA Advanced Systems Analysis Program (ASA) where I was based, and especially my supervisors. As a PhD student in the field of applied land economics, working with mathematicians (as my supervisors and most of my ASA colleagues were), was a very formative experience, as the world of mathematicians is very different to my career so far. Crucially, my supervisors taught me to deal with uncertainty not only in the data but also in the research structure and short-notice changes, and to realise the wider applications and possible extensions of the project rather than being trapped in details. After all, you can return to the details once you have made progress in your overall aims. Moreover, mathematicians are fast thinkers with a “can-do” attitude: a perfect combination for finding a solution in mathematical terms to the next practical problem you face.

I believe I have benefited a lot from this trans-disciplinary cooperation and look forward to working with people from different disciplines again, to learn from their perspectives and expertise.
