SUPPORT CAPACITY OF THE ENVIRONMENTAL SYSTEMS AT THE SÃO NICOLAU RIVER BASIN (SNRB), PIAUÍ
Abstract
This paper is part of a doctoral thesis focused on analyzing the support capacity of the environmental systems at the São Nicolau River Basin (SNRB), Piauí, Brazil, by means of bibliographic and geo-mapping surveys and field visits. Based on geoenvironmental characteristics, the basin was divided into six large environmental systems and their respective support capacity was verified. Results highlight that the Fluvial Plane environmental system, representing 74.61% of the basin’s territory, has very low support capacity. Overall, more than 70% of the SNRB showed unstable environments despite being an area of low population density. Despite such low urbanization, the vast areas occupied by agricultural activities and extractivism together with its geoenvironmental characteristics corroborate the low support capacity of the basin. Thus, adequate planning that is consistent with the basin’s limitations is necessary.
