As a method for both mitigating climate change and preserving biodiversity, develop methods for linking tropical rain forests that have been fragmented while meeting the land use demands of the native people. Specifically, encourage the transition of vegetation by adopting longer cycles for the slash-and-burn farming near Kinabalu Park and Crocker Range Park in the northern half of Borneo to effectively link these parks by creating a stepping stone for wildlife. After clarifying the speed of the transition of vegetation, create models that change the slash-and-burn farming area and cycles, and verify the effects on carbon accumulation and biodiversity.
