My research interest is firstly mechanisms of crop production in relation with resource utilization, responses to climate, and adaptation to abiotic stress under various environmental and managemental conditions. I am interested in rice and water: rice is a staple food in Japan and in many Asian countries but also as a crop and food getting increasingly produced and consumed globally outside Asia. I am currently working on rice production with relation to symbiosis with arbuscular mycorrhiza under different water availability, as well as comparison with a dryland crop, pearl millet
My second research interest is diversity and heterogeneity of agroecosystems in both large and small scales. The heterogeneity of agroecosystem within a target area is small scale environmental variation, which would be related with success and failure of extension of new technologies, becoming as a source of gap between farm yield and potential yield. I have been investigating diversity of rice ecosystems such as rainfed lowlands, deepwater rice, tank irrigation rice and delta rice.
My third research interest is sustainability science; one example of sustainability science approach is to apply both crop production science and agroecology in the same target region. We worked before on sustainability of irrigated fields rehabilitated after the war during Pol Pot time in Cambodia by investigation of spatial variation in rice production and weed species diversity. Another attempt for sustainability science is to study people’s perception about agriculture and rural. We include children too as they will participate in creating future societies.
I hope to contribute to the peace of global and regional societies through academic knowledge generation for crop, environment, and sustainable agriculture.
