IPAM has the objective to promote the recognition of indigenous peoples and lands as an asset for the country’s development and for the climate balance in public policies, guaranteeing their rights and, as a consequence, the protection of forest and water resources in the Amazon. This document shows the strategies and achieviments.
Soil moisture depletion under simulated drought in the Amazon: impacts on deep root uptake
Soil moisture depletion under simulated drought in the Amazon: impacts on deep root uptake
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.
