Over the past years, a series of reports by the World Economic Forum have identified “failure to adapt to climate change” as being of highest concern to society. But in practice, what does adaptation to climate change mean? What makes adaptation particularly challenging for those policymakers, consultants, businesses and other practitioners working on adaptation in practice? An often heard answer is, “Because there are barriers to adaptation.”

In a recent study, we identified numerous examples of barriers to adaptation encountered by practitioners across the globe. These barriers to adaptation emerge from all angles and direction; they can be institutional (e.g. “rigid rules and norms”) resources (e.g. “lack of money”, “uncertain knowledge”) social (e.g. “no shared problem understanding”), cognitive (e.g. “ignorance”, “apathy”).
As scholars, we have proven to be very good in making lists of barriers to adaptation, but rather poor in understanding where these barriers come from, what the concept of “barriers” means to practitioners, why barriers are mentioned at all, or how barriers can be dealt with in an meaningful way. In a follow-up study, colleagues and I argued that listing barriers in isolation from their decision-making context is an interesting first step, but has hardly provided insights in the openings needed to adequately deal with them. In fact, they often lead to a linear argumentative logic – “Not enough money? Then we need more money or we need to spend the money we do have more wisely!” Such superficial advice is not particularly useful to practice.
By delving deeper in the questions of why adaptation is challenging, we found that what practitioners mention as barriers are mere simplifications of what really happened. Barriers become metaphors that capture people’s lived experience and evaluation of the process into easy to communicate messages – e.g. “no money.” We can argue about whether this is truly a barrier, because their interpretation stems from a complex and dynamic chain of events that only makes sense to those that were actively involved. By putting labels on these events, they automatically become static, therefore lacking the necessary insights in the dynamics that caused the process to become challenging and provide the necessary openings to intervene. We concluded that using barriers as units of analysis to explain why adaptation is challenging is therefore flawed: the analytical challenge is to go beyond barriers in search of the explanatory causal processes, or so-called causal mechanisms.
An example: In our study, we identified 24 different barriers encountered by practitioners during the design and implementation of an innovative adaptation measure for temporal water storage in the city center of Rotterdam, the Netherlands. By going beyond this list, we uncovered three underlying mechanisms that explain why the first attempt to implement the so-called “water plaza” failed. One mechanisms, we called the risk-innovation mechanism—which is basically a miscommunication about risk that leads to public outcry.

In this case, the government took a technocratic stance in communicating the risks and benefits of the project. Meanwhile the citizens, as mutual bearers of the risks, wanted to negotiate about what levels of risk were acceptable. By taking such stance the government avoided a moral debate about the risk of the innovation (the innovation was “adaptation”), but the result was angry citizens who to rebelled against the project and the municipal government. This analysis provided openings to change communication strategies – an intervention the project team used successfully in next stages of the process.
Insights from this study have broader implications. It explains, for example, why existing guidelines to support practitioners to overcome barriers to adaptation have not worked well: As I explored more deeply in my thesis, these guidelines are simply not tailored to the real reasons why adaptation is challenging. We can continue to make endless lists of barriers, but to advance theoretically and conceptually, and to provide meaningful strategies to intervene in practice, we need to rethink how we use the concept of “barriers to adaptation” and start searching for underlying causal mechanisms.

IIASA: How did you get interested in hydrology? What drew you to the field?
EW: I came to IIASA after I finished my doctorate at MIT. I worked in the areas of system analysis and statistics related to water resources. During my first sabbatical leave at the Institute of Hydrology in the UK (now the Center for Hydrology and Ecology), I started to collaborate with Keith Beven on hydrological modeling, which started my transition towards the physical side of the water cycle from the policy and systems analysis side.
A few years later, Robert Gurney, then at NASA and now at the University of Reading (UK), asked if I would be on the Science Advisory Committee for NASA’s Earth Observing System (EOS), which was just starting to be planned. This started my research activities in terrestrial remote sensing. Over the next 25 years these elements have played heavily in my research activities.
What have been the biggest changes in hydrology and earth science over your career – either in terms of new understandings, or in how the science is done?
I can name three huge changes, all inter-connected: One is the increase in computational resources. High performance computing—petabyte computing using 500,000+ cores—is now available that allows us to simulate the terrestrial water and energy budgets using physics resolving land surface models at 100m to 1km resolutions over continental scales, and soon at global scales. The second big change is the availability of remotely sensed observations. There are satellite missions that have lasted far beyond their planned lifetimes, such as the NASA EOS Terra mission, where we now have over 15 years of consistent observations. These observations have been reprocessed as algorithms have improved so we can now use the information to understand environmental change at regional to global scales. The third major shift has been computer storage. Large amounts are available at low prices. We have about 500 Terabytes of RAID storage, and can acquire 150TB for about $10,000 or less. This allows us to store model simulations, remote sensing data, and do analyses that were once impossible. Together, these three changes have transformed my field, and the field of climate change related to terrestrial hydrology. Going forward, we have the data, the projections and analytical tools to look at water security in the 21st Century under environmental change.
What insights has remote sensing brought to hydrology?
Remote sensing offers a global consistency that is unavailable with in-situ observations, and offers observations over regions without ground data. This permits us to analyze hydrologic events such as droughts within a global context, and relate these hydrologic events to other drivers like ENSO (tropical Pacific sea surface temperature anomalies) that affect weather and seasonal climate patterns.

What do you see as the key questions currently facing water resources?
The biggest question I see over the next decades is how water security will be affected by environmental change. By environmental change I mean climate change, global urbanization, increasing demand for food, land use and land cover change, pollution, etc. Water security is coupled to food and energy security, and water security is and it is intrinsically linked to the climate system and how that may be changing.
How did IIASA influence your research interests or career?
I made many friendships during my stay at IIASA and I was exposed to world-class research and researchers. This helped me in thinking about important research questions and the types of problems and research that will have impact.
What do you think is the role for IIASA in the worldwide research community?
There are many answers to this question. IIASA plays an important role in providing critical scientific information and analyses related to global issues that go beyond countries – transboundary analyses, and therefore that can provide the scientific basis for global policies. There is an urgent need for more global policies on environmental change and adaptation, food and water security, and environmental refugees, to name just a couple examples in my area.
IIASA has also developed scientific methods and data that can be applied by various groups. For example, IIASA’s world renowned integrated assessment models have been used in climate change modeling for the IPCC and Coupled Model intercomparison Project (CMIP).

Researchers estimate we spend 3 billion hours a week on game playing. CC Image courtesy TheErin on Flickr
On a recent rush hour train ride in London I looked around to see just about everybody absorbed in their mobile phone or tablet. This in itself is not that unusual. But when I snooped over a few shoulders, what really surprised me was that most of those people were playing games. I hope this bodes well for our new game, Cropland Capture, introduced last week.
Cropland Capture is a game version of our citizen science project Geo-Wiki, which has a growing network of interested experts and volunteers who regularly help us in validating land cover through our competitions. By turning the idea into a game, we hope to reach a much wider audience.
Playing Cropland Capture is simple: look at a satellite image and tell us if you see any evidence of cropland. This will help us build a better map of where cropland is globally, something that is surprisingly uncertain at the moment. This sort of data is crucial for global food security, identifying where the big gaps in crop yields are, and monitoring crops affected by droughts, amongst many other applications.
Gamification and citizen science
The idea of Cropland Capture is not entirely unique. There are an astonishingly large number of games available for high tech gaming consoles, PCs and increasingly, mobile devices. While the majority of these games are pure entertainment, some are part of an emerging genre known as ”serious games” or ”games with a purpose.” These are games that either have an educational element or through the process of playing them, you can help scientists in doing their research. One of the most successful examples is the game FoldIt, where teams of players work together to decode protein structures. This is not an easy task for a computer to do, but some people are exceptionally talented at seeing these patterns. The result has even led to new scientific discoveries that have been published in high level journals such as Nature.
Jane McGonigal, in her book Reality is Broken (Why Games Make us Better and How They Can Change the World), estimates that we spend 3 billion hours a week alone on game playing, and that the average young person spends more time gaming by the end of their school career than they have actually spent in school. Although these figures may seem alarming, McGonigal argues that there are many positive benefits associated with gaming, including the development of problem-solving skills, the ability to cope better with problems such as depression or chronic pain, and even the possibility that we might live ten years longer if we played games. If people spent just a fraction of this time on “serious games” like FoldIt and Cropland Capture, imagine how much could be achieved.
Since the game started last Friday, 185 players have validated 119,777 square kilometers of land (more than twice the land area of Denmark).
Cropland Capture is easy to play – simply swipe the picture left or right to say whether there is cropland or not.
Get in the game
You can play Cropland Capture on a tablet (iPad or Android) or mobile phone (iPhone or Android). Download the game from the Apple’s App Store or the Google Play Store. For those who prefer an online version, you can also play the game at: http://www.geo-wiki.org/games/croplandcapture/. For more information about the game, check out our videos at: http://www.geo-wiki.org/games/instructions-videos/. During the next six months, we will be providing regular updates on Twitter (@CropCapture) and Facebook.
The game is being played for six months, where the top scorer each week will be crowned the weekly winner. The 25 weekly winners will then be entered into a draw at the end of the competition to win three big prizes: an Amazon Kindle, a smartphone, and a tablet. The game was launched only last week so there is plenty of time to get involved and help scientific research.

In a new commentary (subscription required) in Nature Geoscience, IIASA researchers Michael Obersteiner, Marijn van der Velde, and colleagues write about the problems facing the world’s food supply as we exhaust our supplies of phosphorus. Projections show that phosphorus supplies could run out in the next 40 to 400 years. In this interview, Obersteiner and van der Velde give more background on the “phosphorus trilemma.”
Fertilizers containing phosphorus are vital for crop production – but phosphorus is limited in availability and growing scarcer.
Why is phosphorus so important?
MV: Phosphorus is essential for life on Earth. It is a key component of DNA and cell membranes, and vital for cellular energy processes. Crops need phosphorus to grow. And to maintain crop production, and to make sure that soils remain productive, we have to add extra nitrogen and phosphorus as fertilizer. This is one of the food security issues in Africa where soils are suffering from nutrient depletion without replenishment.
Where do we get phosphorus and why is that supply in danger?
MO: Phosphorus is ubiquitous in the Earth’s crust. However, most of it is strongly bound in the soil , where plants cannot access it. Modern agriculture (which made human population explode) essentially began when we found ways to extract nitrogen from the air and phosphorus from minerals to make fertilizers for agricultural purposes.
The problem is that minable phosphorus is geographically concentrated in very few places. For example 75% of known reserves are located in Morocco and these reserves are limited. If, for example, political turmoil restricted access to the mines of Morocco, we would be in danger of short-term shortages that could lead to rising food prices or food insecurity in poor countries.
What problems do you expect as phosphorus becomes even more limited?
MO: The biggest problem we face is limited or no access to phosphorus fertilizers by the poor and food insecure.
MV: At the same time, rich countries apply excess fertilizers causing eutrophication to their lakes and rivers, while the poor cannot afford fertilizers.
What can be done about these problems?
MV: More efficient fertilizer application would make fertilizers cheaper to poor farmers, and at the same time help address the environmental problems. But in the long run we need to figure out how to produce food in a way that recycles nutrients at minimum loss rates. (This also includes losses from human excrement!)
To better solve the issues around long-term phosphorus availability and equitable use we also need better data on how much phosphate rock is remaining in the world and where it is located. Countries will need to be persuaded to collaborate on both these issues to ensure equity.
How does IIASA research inform this debate?
MV: In a paper we published earlier this year in PLOS ONE we showed the importance of soil phosphorus and the significant increases in yields that could be achieved in Africa with balanced micro-dosed applications of nitrogen and phosphorus. Available phosphorus in soils is generally low, especially in older weathered soils in the tropics where a lot of the phosphorus can be locked up in iron and aluminum complexes. We are currently investigating what application rates of nitrogen and phosphorus would be optimal for a range of soils and climates. This can then lead to better soil and nutrient management.
MO: In addition researchers in the Mitigation of Air Pollution and Greenhouse Gases program have been very active in finding solutions to the problem. For example: http://www.iiasa.ac.at/web/home/resources/multimedia/Podcasts/Our-Nutrient-World—Wilfried-Winiwarter-on-Reality-.en.html
What should people to know about this issue?
MO: Many things in nature that we like or depend on for our livelihood are substitutable. But phosphorus is in everything we eat and cannot be substituted by any element. If we continue business as usual we will squander this resource and thereby potentially compromising the wellbeing of our daughters and sons.
