Outline of Final Research Achievements

Japanese immigrants and their descendants planting for a century in northern Brazil are the pioneers of agriculture in the Amazon who introduced jute and black pepper there. Since 1970s they developed a successional agroforestry system called SAFTA with the aim of farm diversification. It was copied and popularized by surrounding Brazilian small farmers, and it has gained an international reputation as a sustainable farming method adapted to the tropical rainforest environment of the region. The researcher investigated Japanese immigrant farms and Brazilian farm communities who accepted SAFTA and clarified the diffusion process of this sustainable farming system.
