On May 25th, 2012, after almost two years of discussions in Congress, a new version of the Brazilian Forest Code was approved (Law 12.651/2012). The new law reaffirmed important norms for forest conservation in all the Brazilian biomes. It also established innovative tools for the support of forest activity and the monitoring of its implementation.2 Among these innovative tools, is the Rural Environment Registry (CAR). It is a public electronic registry, self-declaratory and mandatory to be applied to all of the rural properties in the country. Its function is to generate environmental information regarding rural properties, allowing for the “control, monitoring, environmental planning and economic planning and the fight against deforestation” in rural properties nationwide (Article 29, Law 12.651/2012; Decree 7.830/2012).

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.
