Dr. Sonwa visited Japan International Research Center for Agricultural Sciences (JIRCAS) in Tsukuba, Ibaraki with Dr. Oishi, a lecturer of ASC - TUFS, and met Dr. Papa Saliou Sarr. Dr. Papa makes a study of crop, livestock, and environment at JIRCAS, and exchanged ideas about their research fields which could develop REDD+ (Reducing Emissions from Deforestation and Forest Degradation and the Role of Conservation, Sustainable Management of Forests and Enhancement of Forest Carbon Stocks in Developing Countries).
