Métodos de avaliação rápida da integridade ambiental aplicados à bacia do Ribeirão Sozinha, Goiás

Abstract

Environmental monitoring in watersheds depends on reliable environmental diagnostics for better management of natural resources. Thus, this study aimed to perform the environmental assessment of the Ribeirão Sozinha Basin, by relating and identifying the main impacts in the watershed and fluvial environmental by applying a matrix of environmental impact and a rapid assessment protocol. This study also aimed to identify and evaluate the main use and occupation of the soil that could impact water resources, through the use of geotechnologies, and also evaluate the combined use of these three methodologies in the study of selected watershed. Using the protocol it was observed that about 33.3% of the stretches are considered “natural” and 66.7% are “modified” or “impacted”. Already the application of the matrix indicated that the majority of stretches suffer impacts of “high” or “medium” intensity. The land use map that showed the greatest anthropogenic activities in this basin are agriculture and livestock and the majority of impacts on water resources and in the basin are related to these activities. It can be stated that the methodologies used are complementary, and despite the need for adaptations, combined use can be a viable option for environmental monitoring.
