ABSTRACT

 This research aimed to analyze the impacts of anthropic transformations in the springs and riparian forests of the sub-basin of the Botas creek as a subsidy for environmental planning. The methodological procedures used were: bibliographical and documentary analysis, accompanied by field work. They allowed elaborating the geoenvironmental characterization of the sub-basin; identify the natural factors that condition water availability in the sub-basin, carry out an inventory and assess the environmental situation of areas with springs and selected riparian forest fragments; and characterize the historical evolution of the process of occupation and use of springs and riparian forests. The results show that the main conditioning factors of water availability in the sub-basin are: the lithology, the type of climate, the relief pattern, and the type and thickness of the soil, in addition to the use of the soil. In the springs studied, deforestation for the implantation of livestock and the use of water to water the cattle provoked several environmental impacts, causing 60.0% of the 20 areas of springs evaluated fall into classes C (Bad) or D (Terrible) and only two in class B (Good), with none in class A (Excellent). Regarding riparian forests, 88.2% of the 17 fragments analyzed show some level of degradation, predominantly those that are degraded to very degraded, which represent 58.8% of the total. These results show that it is necessary to implement protection and conservation programs for springs and riparian forests in the sub-basin, with the participation of landowners and due inspection. It is also necessary to enhance environmental education aimed at the public in rural areas, aiming at sustainable management of areas with springs and riparian forests.
