Current Research: Terrestrial carbon/climate coupling hot spots

The Amazon River Basin represents a global hotspot where high rates of deforestation and vulnerability to climate change may initiate feedback mechanisms whereby large biome shifts or alterations to biogeochemical cycling may occur. The Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM) has projected large estimates for carbon emissions from deforestation and climate change in tropical regions (Cramer et al. 2004). Thus, the need to accurately forecast the environmental impacts of global change on Amazonian rainforests extends to the global carbon cycle, climatic teleconnections, and biodiversity habitat.

We will investigate potential feedbacks between land-cover and climate change on fire regimes and hydrologic cycling using the framework set by LPJ. In particular, we will investigate changes in fire regime due to land conversion from deforestation and changes in projected precipitation patterns. The resulting impacts on regional hydrology (evapotranspiration and run-off) will then be considered in terms of their feedbacks to fire and future changes in the pattern and distribution of plant functional types.

This project (ER 3) contributes to the science objective 1 (Quantify feedbacks in the global carbon cycle) of GREENCYCLES and has links to the projects of Marlies (ESR III).
