In Asia, the large population with developing economy is driving the fast-growing demands for foods and energy. The region as a whole has so far managed to meet the demands, and many countries have enjoyed the improvements in human nutrition and the quality of life. The increased production of foods and energy has, however, resulted in deterioration of the environment and wide-spread loss of ecosystem services. Continuation of this trend could bring more damages than benefits, and eventually leave them nothing but damaged lands and waters. While technical countermeasures may fall short of preventing all the damages, scientifically sound prediction of the growing threats could facilitate societal decisions to change the course of development away from the disastrous future.
Our research topics include impacts of climatic change, sea-level rise and increasing surface ozone concentration on agriculture. We also focus on adaptation of agriculture to climatic change. We have visited lowland paddies in Mekong Delta in Vietnam, met apple growers in northern Japan, and conducted computer simulation of the greenhouse gas emission from the Japanese tea fields. We also installed the world’s first facility called Ozone-FACE in farmers' fields in Yangzhou, China. In the Ozone-FACE, rice and wheat are grown under elevated ozone concentration in farmers' fields without any enclosures. Our research approach thus includes field survey, field experiment, and computer simulation across the disciplines of agronomy, ecology, and biogeochemistry. We hope that our studies will contribute to better understandings of the climatic and atmospheric change impacts on agriculture and to increased capability of agricultural adaptations to the changing environment in Asia as well as other regions of the world.
