Outline of Final Research Achievements

This study aimed to investigate forest changes and land use drivers, as well as the interactions between local communities and forests, to assess the sustainability of biodiversity and ecosystem services at local to regional scales in tropical areas. In the study area, including rural regions of Sarawak, Malaysia, we found significant forest loss over the past 40 years, not only in plantations and forest management areas but also in villages. Additionally, biodiversity and ecosystem services (above-ground biomass) varied depending on land use. The forest loss was related to the cultivation of global commodity crops such as oil palm, suggesting that interactions among drivers from local to regional levels are the driving force behind forest loss in this region.

Academic Significance and Societal Importance of the Research Achievements

東南アジア熱帯林は、世界的にも炭素貯蔵や生物多様性の中心的役割を担う。本研究で示した土地利用区分間でのバイオマスや生物多様性の違いに関する知見は、それぞれのドライバーが与えるインパクトや地域での役割を明確にしたため、社会的な貢献も大きい。また文系・理系の研究者が共同して行った学際研究であるため、多分野への波及も期待できる
