Tropical forest is highly vulnerable to severe changes in temperature and precipitation because trees biomass growth through photosynthesis is strongly related to those climate variables. Utilizing system thinking-based dynamic modelling this study was mainly aimed to examine the impacts of future climate disturbances on aboveground biomass storage of three tropical tree species groups namely Shorea spp. Dipterocarpus spp. and Palaquium spp. The final result of the study highlighted that when the dynamic simulation was run following five IPCCs climate change scenarios (Constant year 2000 concentrations B1 A1T A2 and A1F1) as well as a scenario of local climate projection for a simulation period of 200 years the aboveground biomass stored in tree species of Shorea spp. Dipterocarpus spp. and Palaquium spp. will significantly decrease. This finding suggests that negative climate responses should be considered to improve long term sustainable forest management under incoming climate uncertainties. Therefore several adaptation measures such as selection of drought-tolerant varieties assisted natural regeneration of functional species or even under-planting of genotype of species adapted to expect future climate conditions should start to be considered seriously.

Abstract

Tropical forest is highly vulnerable to severe changes in temperature and precipitation because trees biomass growth through photosynthesis is strongly related to those climate variables. Utilizing system thinking-based dynamic modelling this study was mainly aimed to examine the impacts of future climate disturbances on aboveground biomass storage of three tropical tree species groups namely Shorea spp. Dipterocarpus spp. and Palaquium spp. The final result of the study highlighted that when the dynamic simulation was run following five IPCCs climate change scenarios (Constant year 2000 concentrations B1 A1T A2 and A1F1) as well as a scenario of local climate projection for a simulation period of 200 years the aboveground biomass stored in tree species of Shorea spp. Dipterocarpus spp. and Palaquium spp. will significantly decrease. This finding suggests that negative climate responses should be considered to improve long term sustainable forest management under incoming climate uncertainties. Therefore several adaptation measures such as selection of drought-tolerant varieties assisted natural regeneration of functional species or even under-planting of genotype of species adapted to expect future climate conditions should start to be considered seriously.
