The Mekong delta is just about the flattest region in Vietnam. In some places, where extensive green rice fields stretched between lines of trees that marked the otherwise perfectly straight horizon, we almost felt like we were back in Holland. A place as flat like this must be as exposed to floods as The Netherlands.
And it is. Even fresh-water areas here have a strong tidal variation. Usually the people take advantage of the steady rising and falling of the water level, irrigating their rice fields and catching small shrimp to grow further in ponds and baskets. Water is central to life in the Mekong delta: until the government improved road infrastructure, most transport took place by boat. The floating markets around Can Tho are popular tourist destinations. But the water is a treacherous friend. In 2000 the Mekong raised about 5 meters high, submerging hundreds of thousands of houses, and drowning hundreds of people as well as cattle and crop. The area saw another big flood in 2011.
Expectations are that the flooding problem will get worse as the global climate gets warmer, bringing heavier rains and a higher sea level. But even a climate change skeptic should be able to see the importance of learning to deal with these heavy floods. Much of what the inhabitants can do makes sense even if no climate change occurs: strengthening dykes, building higher or stronger houses, buying insurance to cover the financial risks of crop and cattle loss. One of the big questions is what the government can or should do (planned adaptation in jargon), and what the local residents do (autonomous adaptation).

One of our PhD students, Phung Thanh Binh, does his research on flood insurance in the Mekong delta, under the supervision of my colleague Zhu Xueqin and myself. Are local residents interested in getting flood insurance, and if so, under what conditions? What insurance premium are they willing to pay for a little bit more coverage? If they have flood insurance, will they still prepare for floods or will they transfer some of the risk to their insurance company?
