| Outline of Final Research Achievements |
This study aims to investigate if social development affects the use of ecosystem services of bioresources and water resources in local communities, Sarawak, Malaysia. Culturally reserved forests (CRFs), which is one of the traditional land use patterns, still hold high tree, animal and rattan species diversity though those were currently fragmented from other forests. Local people in the rural area use diverse bioresources from the CRFs, but those in the suburbs of a town use fewer bioresources in terms of the number of species and frequency. Local people tended to consider that water from CRFs was more important than that from the main river because the latter was currently muddy owing to the plantation development in the upper river area. The results suggested that use and value of ecosystem service could be determined by the dynamic interaction of social and ecological systems, and substitutes of ecosystem services would be a direct factor to affect its demand and use.

| Academic Significance and Societal Importance of the Research Achievements |
1)学術的意義:先行研究では開発が生態系サービスの供給を減少させることに焦点を当てた研究が多かったが、本研究では、開発によって需要自体も変化しており、それが生態系サービスの利用を決める要因である可能性を示した。
2) 社会的意義:本研究は、東南アジア熱帯の森林減少・生態系サービスの劣化が進む地域を対象とする。この成果は、生物多様性条約やIPBESでも掲げる生態系サービスの持続的利用のためのケーススタディとしても貢献が期待できる。
