Water-carbon coupling in tropical ecosystems

Main content start
Diagram of soil moisture vs burned areas with Ignition probability

Despite exhibiting among the largest water and carbon fluxes on earth, tropical ecosystems are generally under-studied relative to those in the mid-latitudes, as in situ measurements are logistically more difficult than in developed countries. We are particularly interested in the wet tropics across the under-studied old-world continents. Past and current work focuses on understanding the seasonal variability of water uptake and evapotranspiration in the Congo river basin. We also study the interplay between anthropogenic hydrologic change (e.g. canal building and restoration), land use change, and fire in Insular Southeast Asia.
