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.

Is open science the way to go?

By Luke Kirwan, IIASA open access manager

At this year’s European Geosciences Union a panel of experts convened to debate the benefits of open science. Open science means making as much of the scientific output and processes publicly visible and accessible, including publications, models, and data sets.

In terms of the benefits of open science the panelists—who included representatives from academia, government, and academic publishing—generally agreed that openness favors increased collaboration and the development of large networks, especially in terms of geoscience data, which improves precision in the interpretation of results. There is evidence that sharing data and linking to publications increases both readership and citations. A growing number of funding bodies and journals are also requiring researchers to make the data underlining a publication as publicly available as possible. In the context of Horizon 2020, researchers are instructed to make their data ‘as open as possible, as closed as necessary.’

This statement was intentionally left vague, because the European Research Council (ERC) realized that a one size fits all approach would not be able to cover the entirety of research practices across the scientific community, said Jean-Paul Bourguignon, president of the ERC.

Barbara Romanowicz from Collège de France and Institut de Physique du Glove de Paris also pointed to the need for disciplines to develop standardized metadata standards and a community ethic to facilitate interoperability. She also pointed out that the requirements for making raw data openly accessible are quite different to those for making models accessible. These problems require increased resources to be adequately addressed.

Playing devil’s advocate, Helen Glaves from the British Geological Survey pointed to several areas of potential concern. She questioned whether the costs involved in providing long-term preservation and access to data are the most efficient use of taxpayers money. She also suggested that charging for access could be used to generate revenues to fund future research. However, possibly a more salient concern for researchers that she raised was  the fear of scientists that making their data and research available in good faith, could allow their hard work to be passed off by another researcher as their own.

Many of these issues were raised by audience members during the questions and answer session. Scientists pointed out that research data involved a lot of hard work to collate, they had concerns about inappropriate secondary reuse, jobs and research grants are highly competitive. However, the view was also expressed that paying for access to research fundamentally amounts to ‘double taxation’ if the research has been funded by public money, and that even restrictive sharing is better than not sharing at all. It was also argued that incentivising sharing through increased citations and visibility would both help encourage researchers to make their research more open and aide researchers in the pursuit of grants or research positions. To bring about these changes in research practices will involve investing in training the next generation of scientists in these new processes.

Here at IIASA we are fully committed to open access and in the library, we assist our researchers with any queries or issues they may have with widely sharing their research. As well as improving the visibility of research publications through Pure, our institutional repository, we can also assist with making research data discoverable and citable.

Bringing satellite data down to Earth

By Linda See, IIASA Ecosystems Services and Management Program

Satellites have changed the way that we see the world. For more than 40 years, we have had regular images of the Earth’s surface, which have allowed us to monitor deforestation, visualize dramatic changes in urbanization, and comprehensively map the Earth’s surface. Without satellites, our understanding of the impacts that humans are having on the terrestrial ecosystem would be much diminished.

Over the past decade, many more satellites have been launched, with improvements in how much detail we can see and the frequency at which locations are revisited. This means that we can monitor changes in the landscape more effectively, particularly in areas where optical imagery is used and cloud cover is frequent. Yet perhaps even more important than these technological innovations, one of the most pivotal changes in satellite remote sensing was when NASA opened up free access to Landsat imagery in 2008. As a result, there has been a rapid uptake in the use of the data, and researchers and organizations have produced many new global products based on these data, such as Matt Hansen’s forest cover maps, JRC’s water and global human settlement layers, and global land cover maps (FROM-GLC and GlobeLand30) produced by different groups in China.

Complementing Landsat, the European Space Agency’s (ESA) Sentinel-2 satellites provide even higher spatial and temporal resolution, and once fully operational, coverage of the Earth will be provided every five days. Like NASA, ESA has also made the data freely available. However, the volume of data is much higher, on the order of 1.6 terabytes per day. These data volumes, as well as the need to pre-process the imagery, can pose real problems to new users. Pre-processing can also lead to incredible duplication of effort if done independently by many different organizations around the world. For example, I attended a recent World Cover conference hosted by ESA, and there were many impressive presentations of new applications and products that use these openly available data streams. But most had one thing in common: they all downloaded and processed the imagery before it was used. For large map producers, control over the pre-processing of the imagery might be desirable, but this is a daunting task for novice users wanting to really exploit the data.

In order to remove these barriers, we need new ways of providing access to the data that don’t involve downloading and pre-processing every new data point. In some respects this could be similar to the way in which Google and Bing provide access to very high-resolution satellite imagery in a seamless way. But it’s not just about visualization, or Google and Bing would be sufficient for most user needs. Instead it’s about being able to use the underlying spectral information to create derived products on the fly. The Google Earth Engine might provide some of these capabilities, but the learning curve is pretty steep and some programming knowledge is required.

Instead, what we need is an even simpler system like that produced by Sinergise in Slovenia. In collaboration with Amazon Web Services, the Sentinel Hub provides access to all Sentinel-2 data in one place, with many different ways to view the imagery, including derived products such as vegetation status or on-the-fly creation of user-defined indices. Such a system opens up new possibilities for environmental monitoring without the need to have either remote sensing expertise, programming ability, or in-house processing power. An exemplary web application using Sentinel Hub services, the Sentinel Playground, allows users to browse the full global multi-spectral Sentinel-2 archive in matter of seconds.

This is why we have chosen Sentinel Hub to provide data for our LandSense Citizen Observatory, an initiative to harness remote sensing data for land cover monitoring by citizens. We will access a range of services from vegetation monitoring through to land cover change detection and place the power of remote sensing within the grasp of the crowd.

Without these types of innovations, exploitation of the huge volumes of satellite data from Sentinel-2, and other newly emerging sources of satellite data, will remain within the domain of a small group of experts, creating a barrier that restricts many potential applications of the data. Instead we must encourage developments like Sentinel Hub to ensure that satellite remote sensing becomes truly usable by the masses in ways that benefits everyone.

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.
