Outline of Final Research Achievements

Although farmers in Malawi have not used human waste for agriculture, we found that farmers' needs are high and that this could be a way to improve land productivity with limited labor. In addition, it was found that if combined with soil conservation technology that requires less labor, it is possible to establish a system to sustainably use the applied nutrients without letting them flow out of the system.

Academic Significance and Societal Importance of the Research Achievements

高価な化学肥料の購入が難しい途上国の農民にとって、自前で養分が確保できる屎尿に対するニーズが高いこと、そのニーズに後押しされる形で、屎尿利用に対する生理的嫌悪感は克服可能であることがわかった。また、人口増加が進む途上国であっても、農村では出稼ぎ等の理由で労働力の不足が顕在化しており、労働力を節約できる技術に対するニーズが高いこともわかった。
これらの事実から、労働力をセーブしつつ、生産性を上げることができる屎尿利用が、今後有望な技術であることを実証できた。
