Outline of Final Research Achievements

The purpose of this study was to contribute to the examination of issues and remedial measures concerning grapes by understanding the supply chain and clarifying the profit structure and distribution among actors with regard to the production and distribution of profit, which are expected to have high economic potential in the semi-arid Dodoma Region of Tanzania.
As a result, I was able to present a new understanding of the variation of buyers and the characteristics of actors in the supply chain in comparison with previous studies. In addition, the study focused on transaction practices to understand the profit structure among actors, and showed the large number of credit transactions, the characteristics of farmers that make these transactions possible, and the possibility of variation among buyers, etc. It was considered that understanding the actual situation of buyers’ financing and improving their situation would lead to solving issues related to grape distribution.

Academic Significance and Societal Importance of the Research Achievements

本研究では未だ経済水準の低い事例地において、牽引役として期待されるブドウについて、サプライチェーンの多様性と複雑性を明らかにし、アクター間の商取引の実態、とくに農家と買手との信用取引について、その背景、構造的特徴、改善のためのキーポイントを明らかにしたうえで、買手の多様性理解の必要性についても指摘した。このことは、農業経済学・開発経済学において重要な農産物をめぐるフードシステムや農産物取引に関して、主要な理解と必ずしも同一ではない新たな考察結果を提供するだけでなく、商業的農業が推進される多くのアフリカ諸国の農業政策という実社会に対しても重要な知見を提供できるものと考える。
