Research Abstract

Rubber (Hevea brasiliensis Müll. Arg.) plantations are a viable resource for the economics of Southeast Asian countries. They are rapidly expanding into both climatically optimal and sub-optimal environments throughout mainland Southeast Asia, potentially change the partitioning of water, energy, and carbon at multiple scales, compared with traditional land covers that are being replaced. To provide a useful tool for building strategy of rubber plantation management, e.g., balancing the rubber plantation productivity and the environmental conservation, we developed the Spatially Explicit Individual-Based (SEIB) Dynamic Global Vegetation Model (DGVM) applicable to simulate both primary and latex productivities in rubber plantations (SEIB-RP). SEIB-RP can take the climatic impacts on productive processes into consideration, and thus, allows us to project the future rubber plantation productivities under climate change conditions.
