Outline of Final Research Achievements

This study is an empirical study of smallholder coffee farmers and the sustainability of ecosystems in Sekampung Watersheds, Lampung Province, Sumatra, Indonesia. Based on a questionnaire survey to over 400 farmers, alternative land-use systems and the coffee agroforestry system have been analyzed. Results show that the adoption of environmentally friendly techniques and that of coffee eco-certification program can provide not only significant positive financial benefits but also desirable environmental benefits to the farmers. It is also analyzed and concluded that the use of payment for ecosystem services (PES) would enable to generate greater ecosystem services, in addition to environmental benefits to the region.

Academic Significance and Societal Importance of the Research Achievements

本研究では、発展途上国農業において食料安全保障と環境保全は両立するのか、あるいは環境保全型の農業手法を途上国農業の現場にいかに適用しうるかについて、インドネシア・スマトラ島を事例対象として実証分析し、生態系サービスの価値に着目して経済的および水文学的な検証を試みた。実証分析の結果、スマトラ島農村部では貧困に伴う食料不足や栄養失調などが顕在化しつつあり、他方では、河川の水質悪化、洪水や水不足の顕在化など、生態系サービスの劣化が進行していることを解明した。さらに、近年増大しつつある水質汚染や洪水問題への対応など、都市部とその近郊地域を含めた流域全体を対象とする分析の必要性についても提起した。
