一般講演（口頭発表） G01-02 （Oral presentation）
Tropical forests close to people's homes have important roles, which are different from those in remote areas. However, the former have received less international attention because of lower biomass and biodiversity than the latter. In this study, we assessed 40-year forest cover changes in 90 rural villages in Sarawak, Borneo, based on land-cover maps of four different time periods. We also explored drivers of these changes using random forest models incorporating different environmental and social factors. We found a rapid polarization in the forest-cover rates among the villages and loss of land-cover heterogeneity within the villages. This may reflect the decrease and increase of effects of the village and external drivers, respectively, on the forest cover during the period.
