The eastern Amazon Basin may become drier as a result of less regional recirculation of water in a largely deforested landscape and because of increased frequency and intensity of El Niño events induced by global warming. Drier conditions may affect several plant and soil microbial processes, including soil emissions of CO2, CH4, NO, and N2O. We report here unanticipated results of a pilot study that was initiated to test the feasibility of a larger-scale throughfall exclusion experiment. In particular, soil drying caused a switch from net consumption of atmospheric CH4 by soils in the control plot to net CH4 emission from soils in the experimentally dried plot.

Deforestation scenarios in the area of influence of the Tapajós Hydropower Complex
A summary of an assessment commissioned by WWF and developed by IPAM aimed to provide a
better understanding of the occupation dynamics in the Tapajós basin region and the effects of the proposed Tapajós Hydropower Complex (in English).
