Abstract:

The abandonment of deforested areas in the Amazon have resulted in a landscape characterized by a mosaic of several land covers, mainly the natural forest, pastures and secondary growth. This thesis aims to evaluate the seasonal and spatial variability of the fluxes of evapotranspiration over those land covers in Central and Southwestern Amazonia by eddy covariance and scintillometry. The purpose is to investigate whether natural recovery counterbalances the effects caused by anthropogenic actions on the water cycle components. Besides that, the impact of future scenarios of land use and land cover change in combination with global climate change on river discharges and hydropower was also evaluated in an Amazon tributary by explicitly modeling the role of each land cover on evapotranspiration. This work found that secondary forest growth transpires 20% more than primary forest, minimizing the impacts of deforestation on evapotranspiration, also impacting hydroelectricity under a changing climate.
