FPE VERDE: Recompensando pela conservação da biodiversidade e manutenção da integridade funcional dos ecossistemas

Deep root water uptake in tropical Amazonian forests has been a major discovery during the last 15 yr. However, the effects of extended droughts, which may increase with climate change, on deep soil moisture utilization remain uncertain. The current study utilized a 1999–2005 record of volumetric water content (VWC) under a throughfall exclusion experiment to calibrate a one-dimensional model of the hydrologic system to estimate VWC, and to quantify the rate of root uptake through 11.5 m of soil.

Negotiations are proceeding for a new international climate change regime that will compensate tropical nations that reduce their carbon emissions from deforestation and forest degradation. In anticipation of this new mechanism designed to slow deforestation,...
