I have been doing research based on household survey data collected in various rural areas of developing countries mainly in Sub-Saharan Africa but including Asia. Common problems in those areas are that farm households are subject to a number of risks such as drought, war, diseases, and so on, and that most of them are in poverty. My research is to investigate how farm households cope with such an environment and to consider what kind of policy supports is possible. Among them, I have been focusing on technology dissemination in agricultural and institutions for resource management.

My current research topics are as follows. (1) Panel datasets are being constructed in Zambia and Burkina Faso for the study on risk and poverty of rural households in Sub-Saharan Africa. (2) As for the relationship between agricultural technologies and economic development in Sub-Saharan Africa, household surveys are going on in Ghana, Senegal, and Kenya focusing on rice production. (3) Concerning economic analyses of institutions for natural resource management in low-income areas, household surveys are being conducted in mountainous regions in Laos and Yunnan Province of China.
