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).
