Last year’s record flooding in the Chao Phraya River’s watershed caused $40 billion in damages and left one third of Thailand—including parts of Bangkok, the capital and largest city—underwater for weeks. The prolonged media coverage, however, completely drowned out most recollections of the record drought that the country experienced in 2010.
For Thailand, managing the agricultural challenges presented by climate change means planning to handle both too much water and too little. One solution, Managed Aquifer Recharge (MAR), sets aside land in upstream areas of major rivers to “capture” floodwater and direct it into natural underground aquifers. With fully “charged” aquifers, farmers could then maintain rice yields during dry spells.
Matthew McCartney, principal researcher for the International Water Management Institute, and Theerasak Tangsutthinon of Thailand’s Department of Groundwater Resources led a tour of a MAR project 50km north of Bangkok that showed both the potential of this solution as well as the challenges it brings.
This was the subject of a slide show featuring my photos that I created for the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). I also secured coverage of the tour with the Christian Science Monitor and National Geographic.
