BG2.11

Tropical ecosystems play an important role for the regional and global climate system through the exchange of greenhouse gases (GHG), water and energy and provide important ecosystem services that we as humans depend on, such as wood, foods, and biodiversity. Historic and recent human activities have, however, resulted in intensive transformation of tropical ecosystems impacting on the cycling of nutrients, carbon, water, and energy.

Here we invite contributions that provide insights on how land-use and land-use change influences biogeochemical cycles and ecohydrology in tropical ecosystems at the plot, landscape, and continental scale. Examples include nitrogen and carbon cycles in soil and vegetation, the exchange of GHG between soil and atmosphere as well as ecosystem and atmosphere, changes in the energy balance, impacts on the water cycle, scaling issues from plots to country to continent; and the influence of management activities (i.e. fertilization, drainage, etc.) on GHG fluxes.

The session covers forests, but also managed land-use systems such as agriculture, pastures or oil palm plantations. Experimental studies (chamber or eddy covariance flux measurements, stable isotopes, sap flux), inventories, as well as remote sensing or modelling studies are welcomed.
