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: 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.

A world on the move

by Julia M. Puaschunder, alumna of the IIASA Young Scientist Summer Program 2016.

The world is on the move. Currently, more than 250 million people live outside their countries of birth. Of the moving masses, an estimated 6% are refugees fleeing across borders to more favorable environments. The ongoing European refugee crisis has increased the pressure to reap the benefits from migration while alleviating the burdens of societal movement.

worldregions_2005-10

Estimates of directional flows between 123 countries between 2005-2010. Only flows containing at least 50,000 migrants are shown. “The Global Flow of People” (www.global-migration.info) is by Nikola Sander, Guy Abel & Ramon Bauer, and published in Science as “Quantifying global international migration flows” in 2014 (vol. 343: 1520-152).

Concerns were recently raised as to whether granting asylum to refugees—who often make up the most productive parts of their original populations—prevents (re)development in their fractionated home countries? An important consideration absent in these debates are the monetary gifts migrants send to their family members back home.

The World Bank estimates that migrants currently return around 450 billion US Dollars per year to the developing countries they came from, and this number is expected to rise. These monetary remittances have multiple positive impacts, including economic growth. As refugees are primarily younger to middle-aged, their remittances likely pay for their wives and children’s access to medical care and education, or support their parents when pension systems are missing.

Intergenerational monetary transfers are therefore the focus of my recent publication Gifts Without Borders. Contrary to conventional institutionalized sustainable development, remittances grounded in intergenerational care benefit from communication within families. Long-lasting family ties allow direct feedback. People truly care about their loved ones back home and families share their day-to-day experiences honestly. Intergenerational remittances beyond borders are thus a purer and potentially longer-enduring pathway to sustainable development, as these stable funding streams’ impact is more accountable than standard international aid.

Based on World Bank and OECD data covering almost all countries of the world, my forthcoming publication in the book ‘Intergenerational Responsibility in the 21st Century’ highlights that the intergenerational glue of a migrating population helps countries lacking socially responsible and future-oriented public sectors. Rather than blaming asylum-granting countries for removing the labor force from fragile territories, hosting refugees is portrayed as making use of human capital in stable economies, while refugees—at the same time—develop their former homelands by direct monetary contributions in a natural, transparent, and accountable way. In the age of migration, analyzing intergenerational networks and their financial flows is an important, but unexplored, facet of sustainable development. My findings open prospective research avenues on how we can align the economic outcomes of human capital mobility with sustainable development.

The IIASA Young Scientists Summer Program granted a vibrant setting to discuss my findings in a group of international, diverse, and multi-disciplinary future academic leaders during this summer, which was filled with beautiful moments in the historic Schloss Laxenburg in Austria. Recently IIASA also launched a Joint Research Centre of Expertise with the European Commission on Population and Migration, which aims to predict how migration will impact future economies and societies. In addition, the Advanced Systems Analysis (ASA) Program hosts the ‘Economic migration, capital flows, and welfare’ collaboration between ASA and the World Population Program to model dynamics of economic migration and investment. This research is also directly related to my New School Economic Review paper ‘Putty Capital and Clay Labor: Differing European Union Capital and Labor Freedom Speeds in Times of European Migration,’ which elucidates trade differences in capital and labor flows gravitating the benefits and burdens of globalization unequally and the potential problems arising for the European project from migration.

Above all, attending the IIASA 2016 Alpbach-Laxenburg Group Retreat at the European Forum Alpbach helped to enhance my understanding of the relationship between migration and intergenerational responsibility. All these endeavors are targeted at contributing to sustainable development in a world on the move.

How coordination can boost the resilience of complex supply chains

By Célian Colon, PhD student at the Ecole Polytechnique in France & IIASA Mikhalevich award winner

How can we best tackle risks in our complex and interconnected economies? With globalization and information technologies, people and processes are increasingly interdependent. Great ideas and innovations can spread like wildfire. However, so can turbulence and crises. The propagation of risks is a key concern for policymakers and business leaders. Take the example of production disruption: with global supply chains, local disasters or man-made accidents can propagate from one place to another, and generate significant impact. How can this be prevented?

As part of my PhD research, I met professionals on the ground and realized that supply risk propagation is a particularly tricky issue, since most parts of the chains are out of their control. Supply chains can be very long, and change with time. It is difficult to keep track of who is working with whom, and who is exposed to which hazard. How then can individual decisions mitigate systemic risks? This question directly connects to the deep nature of systemic problems: everyone is in the same boat, shaping it and interacting with each other, but no one is individually able to steer it. Surprising phenomena can emerge from such interactions, wonderfully illustrated by bird flocking and fish schooling.

As an applied mathematician thrilled by such complexities, I was enthusiastic to work on this question. I built a model where firms produce and interact through supply chain relationships. Pen and paper analyses helped me understand how a few firms could optimally react to disruptions. But to study the behavior of truly complex chains, I needed the calculation power of computers. I programmed networks involving a large number of firms, and I analyzed how localized failures spread throughout these networks, and generate aggregate losses. Given the supply strategy adopted by each firm, how could systemic risk be mitigated?

With my collaborators at IIASA, Åke Brännström, Elena Rovenskaya, and Ulf Dieckmann, we have highlighted the key role of coordination in managing risks. Each individual firm affects how risks propagate along the chain. If they all solely focus on maximizing their own profit, significant amounts of risk remain. But if they cooperate, and take into account the impact of their decisions on the risk profile of their trade partners, risk can be effectively mitigated. Reducing systemic risks can thus be seen as a common good: costs are heterogeneously borne by firms while benefits are shared. Interestingly, even in long supply chains, most systemic risks can be mitigated if firms only cooperate with only one or two partners. By facilitating coordination along critical supply chains, policy-makers can therefore contribute to the reduction of risk propagation.

Drawing robust conclusions from such models is a real challenge. On this matter, I benefited from the experience of my IIASA supervisors. Their scientific intuitions greatly helped me focusing on the most fertile ground. It was particularly exciting to borrow techniques from evolutionary ecology and apply them to an economic context. Conceptually, how economic agents co-adapt and influence each other shares many similarities with the co-evolution of individuals in an ecological environment. To address such complex issues, I strongly believe in the plurality of approaches: by illuminating a problem from different angles, we can hope to see it more clearly!
