Simulation of resource-effective management strategies in tropical forests

On a global scale, highest deforestation rates occur in tropical least developing countries. As a consequence of human-induced climate change and land-use change, the forests’ ecological balance is disturbed, so that the permanent provision of their ecosystem services is not guaranteed and losses in biodiversity and forest resources occur. However, estimating long-term effects of deforestation and climate change on forest growth dynamics in the tropics is important in order to provide policy-makers with science-based recommendations from which appropriate plans of action can be derived.
This study‘s goal is to evaluate long-term responses of forest growth regarding management strategies in the context of climate change. To evaluate possible consequences for the local forest ecosystems, we use the individual-oriented forest simulation model FORMIND. We parameterize the model utilizing field observation data including forest inventories, dendrochronological, and climate measurements. By testing different parameter settings for logging and climate, we analyse explicit simulation scenarios focusing on aboveground biomass and carbon dynamics. Our climate change scenarios are modelled on findings of the 5th IPCC Assessment Report. In addition, we intend to evaluate the effects of a wider range of management strategies on long-term forest growth dynamics by implementing an updated version of the management module to our existing forest simulation model. This will allow the development of management strategies that are more economic and ecological friendly.
