Outline of Final Research Achievements

The purpose of this study is to investigate the characteristics of SAFTA, which is the successional agroforestry system developed by Japanese immigrants in Tome Acu in Para of northern Brazil and its development history from a farm management point of view. In February and in April through May, 2016, we conducted the field study under which various data and information were obtained from local organizations as well as through the farm management survey for 25 Japanese-Brazilian farms. Our analysis of the data obtained reveals that SAFTA is a rational and flexible farm management system based on multiple fruit trees and crops and is viewed as the consequence of repeated trails and errors by Japanese immigrants who had pursued the optimum farm management, in face with catastrophic national economy, great price volatility in international commodity markets and unstable and rapidly-changing tropical environments, and the aftermath of damages on pepper cropping due to its monoculture.
