Evapotranspiración en áreas conservadas y deforestadas de la amazonia colombiana durante el periodo 2001-2018

Abstract

The objective of the present study was to analyze the behavior of evapotranspiration (ET) focusing on the development that deforestation has had over time in the Colombian Amazon using comparative statistics between transformed and nontransformed areas. The study area is comprised in the Colombian Amazon specifically in the areas of the Amazon foothills located in the north-west and the deforestation arc located in the departments of Caquetá, Putumayo, Guaviare, Cauca and Nariño. ET orbital data of the product MOD16 from the period 2001-2018, layers of land surface coverings for the years 2002, 2007, 2014 and 2016 obtained from the Amazon Institute of scientific research SINCHI were used. Regarding the consequences of deforestation, the analyzes indicated that the ET of deforested areas increases with respect to conserved areas. The results obtained showed a higher behavior in the ET in greater in transformed or deforested areas than in the conserved areas, that is, the pixels with information from the deforested areas had a positive relationship against the pixels in the conserved areas.
