Interview: A community-based approach to managing human-wildlife conflicts

Ziyun Zhu is a PhD student at Peking University Centre for Nature and Society, and research assistant at the Shanshui Conservation Center, China. He is currently attending the IIASA Young Scientists Summer Program and talks to Science Communication Fellow 2017 Caroline Njoki about his current research on wildlife damage insurance schemes as a strategy to manage human-wildlife conflict.

What is your research about and what do you aim to achieve during your time at IIASA?
Wildlife insurance schemes compensate local people in case wild animals attack their livestock, or damage their crops or property, if a wolf kills a sheep, for instance. These schemes are a relatively new tool for mitigation of human-wildlife conflicts and there isn’t sufficient information on when this is the best option and where other tools may apply. My research is to clarify the different scenarios where insurance can work, based on existing insurance projects and other mitigation measures from other parts of the world. This will help improve insurance schemes for other areas.

Tell us more about the community wildlife insurance scheme?
The Tibetan Plateau contains unique wildlife including snow leopards, wolves, and Tibetan brown bears. The people living on the plateau keep yaks and sheep, and co-exist with wildlife. However, there are cases when interactions between people and carnivores result in conflict and disruption of people’s livelihoods, and may lead to retaliatory killing of wildlife.

A voluntary Community Wildlife Insurance Scheme, started by the non-governmental organization Shanshui Conservation Center in 2008, runs on premiums contributed by the members. This makes the scheme more self-sufficient than traditional government-funded compensation, which often lacks funding. The premium depends on type of animal (sheep or yak) and number they keep and also covers damage to their homes by bears. The validation process is also streamlined to ensure claims are paid out quickly.

Members meet annually to elect leaders to manage the pilot scheme, evaluate performance, and review the premiums in line with market trends. In consultation with the members, leaders determine the premium based on the market but also make them affordable. The members are also encouraged to put in place other mitigation measures.

Herders have negative attitudes towards brown bears, yet bears attacking livestock is rare compared to other predators. Why is that?
The availability of pasture on the plateau is seasonal. Herders and their families lived in yak-wool tents until a government initiative to support them to build winter houses in the mid-1990s. When herders move from their winter to summer grounds, bears sometimes break into their mud brick houses, consume stored food, and damage property. The herders must then pay for repairs and replacements, hence the strong negative attitude towards bears. Working closely with local communities to raise awareness and develop suitable mitigation measures is key to promoting co-existence with wildlife.

 What are your highlights from working on the Tibetan Plateau?

During fieldwork to determine presence of the snow leopards on the plateau, which are very shy and elusive, one dashed from above the cave and disappeared in the rocks while we were placing camera traps. This was definitely a highlight for me. I also enjoy working with the people, who possess a rich indigenous ecological knowledge. My PhD aims to document this information and how it may contribute to conservation of Tibetan’s biodiversity. For instance, the collection of plants and hunting of animals are not allowed in certain areas designated as sacred or of high cultural importance. There is little human interference, leaving much of the area pristine.

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.

Why Germany and not Japan is the leader in renewable energy

By Jessica Jewell, IIASA Energy Program

Why have Germany and Japan, two large, and in many respects similar developed democracies pursued different energy options? A recently published study examines why Germany has become the world’s leader in renewable energy while phasing out its nuclear power and Japan has deployed only a trivial amount of renewables while constructing a record number of nuclear reactors.

The widespread story is that Germany rejected nuclear power in a politically bold move after Fukushima and instead pursued ‘Energiewende’ prioritizing wind and solar energy to combat climate change. Leading scholars such as Amory Lovins described Japanese policymakers as manipulated by the nuclear lobby, clinging to their old ways, and unwilling to properly support renewable energy. The lesson to other countries is that public anti-nuclear sentiments and a capable democratic government is what it takes to turn to decentralized renewable energy.

This research shows that these stories are myths. As I and my coauthor wrote in a letter to the editor in Nature last year, Japan had ambitious renewable targets already before Fukushima and there is no evidence that these have been affected by its nuclear plans. The same holds for Germany: its targets for renewable energy were not affected by the change in its nuclear strategy following Fukushima’s disaster in 2011.

In fact, the differences between Germany and Japan started not in 2011 after Fukushima, but some 20 years earlier in the early 1990s when Japan’s electricity consumption was rapidly growing and it desperately needed to expand electricity generation to feed demand that could not be matched with very scarce domestic fossil fuels. Furthermore, Japan was developing ‘energy angst’ related not only to its high dependence on Middle Eastern oil and gas but also to potential competition with China’s with its rising appetite for energy. At the same time, Germany’s electricity consumption stagnated in the 1990s and its energy security improved following the end of the Cold War. Germany was also one of the world’s largest coal producers and could in principle supply all its domestic electricity from coal. As a result, in the 1990s, Japan was forced to build nuclear power plants, but Germany could easily do without them.

There was another important development in the early 1990s: wind power technology diffused to Germany from neighboring Denmark. This was triggered by an electricity feed-in-law of 1990s, which obliged German electric utilities to buy electricity from small producers at close-to-retail prices. The law, which aimed to benefit a small number of micro-hydro plant owners, unexpectedly led to almost a 100-fold rise in wind installations in Germany. Although still insignificant in terms of electricity, this development created a large and vocal lobby of owners and manufacturers of wind turbines. In the early 2000s, the wind sector provided less than one-tenth of nuclear electricity but had more jobs than in the nuclear sector. In contrast, Japan’s similar policies of buying wind energy from decentralized producers did not result in any considerable growth of wind power, because the Danish technologies prevalent in the early 1990s could not be as easily diffused to Japan.

By the turn of the century, the electricity sectors in Germany and Japan still looked largely similar, but the political dynamics could not be more different. In Germany, a huge politically-powerful coal sector was represented by Socio-Democratic Party and the so-called ‘red-green’ coalition was formed with the Green party, who represented the rapidly growing wind power sector. The stagnating nuclear industry, however, had not seen new domestic orders or construction for 15 years and large industrial players like Siemens had begun to diversify away from it. All this was in the context of a positive energy security outlook and declining electricity prices. In contrast, in Japan, the nuclear sector had vigorously grown over the last decade and was becoming globally dominant by acquiring significant manufacturing capacities. Nuclear power was the only plausible response to the energy angst and it lacked any credible political opponents: the domestic coal sector in Japan virtually did not exist (Germany had around 70,000 coal mining jobs, Japan – about 1,000) and wind had never taken off.

The results of these very different political dynamics were predictably different: the red-green coalition in Germany legislated nuclear phase-out in 2002 and unprecedented financial support for renewables in 2000, while retaining coal subsidies and triggering construction of new coal power plants. Japan continued to support solar energy in which it had been the global leader since the 1970s but it also adopted a plan for constructing many more nuclear reactors designed to substitute imported fuels. Fukushima, rather than highlighting differences actually made the energy trajectories of two countries more similar as both countries began to struggle to replace their aging nuclear capacities with new renewables.

How does this story relate to wider questions such as: why are some countries more successful in deploying renewables than others? The answer is not in ‘stronger political will’ and in the strength of climate change concerns, but in economy, geography, and the structure of energy systems. Political wins for renewables and the climate can also be the result of dubious political compromises such as the alliance with the coal lobby in Germany, which led to the rapid growth of renewables and demise of nuclear power. It may be particularly difficult for countries with fossil fuel resources to implement renewable energy policies if they lead to the contraction of domestic coal, gas or oil industries.

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.
