Research Keywords Swidden Agriculture, Natural Resources Use, Subsistence System, Indigenous Eco-knowledge, Mainland Southeast Asia


My special field of study is geography, which can encompass the research of absolutely anything relating to the surface of the earth. In particular, I focus on rural areas in Mountain Mainland Southeast Asia (MMSEA). Now, I would like to gain a full understanding of human-nature interactions, looking specifically at subsistence activities which have allowed the sustainable and intelligent use of nature by humans, such as natural resource gathering and swidden agriculture. Furthermore, I would like to create a new model to review current socio-economic structures that consume the earth's natural resources. I have been conducting field research in MMSEA for 15 years now, but I still find something new every time I visit. I am excited to see what new discoveries and developments this Global COE will also hold.

Research Themes

  1. Subsistence Change in Rural Villages and Flows of People, Goods and Information (Field: Mainland Southeast Asia)
  2. Indigenous Eco-knowledge in Local Residents and Plant Use in Mountainous Regions (Field: Laos)
  3. The Value of Swidden Agriculturen and the Significance of Slash-and-Burn Research (Field: all regions where swidden agriculture is practiced)
  4. Changes amongst local farmers exporting food products into Japan from Thailand (Field: Thailand)
  5. Product Use Patterns and Diffusion of Unsalted Fermented Soybean Foods (Field: Mainland Southeast Asia)
  6. Relationship between Tabu-noki (Machilusspp.) use in the two regions; MMSEA and Satoyama in Japan (specifically Miyazaki Prefecture (Japan), Thailand, Laos)
