Espacialização da insegurança hídrica na bacia do Riacho Forquilha, semiárido cearense

Abstract

Water insecurity is a growing challenge in semi-arid regions, compromising the quality of life of local populations. This study spatializes water insecurity in the Riacho Forquilha Basin, located in the municipality of Quixeramobim, Ceará, through cartographic approaches and spatial analyses. For this purpose, geoprocessing techniques in QGIS and household surveys based on the HWISE scale were used to assess the water vulnerability of residences in the study area. The results indicated the presence of critical hotspots of water insecurity, probably associated with inadequate infrastructure and the low quality of available water. The statistical analysis performed shows that the spatial distribution of the data does not influence the presented vulnerability data, reinforcing the need for public policies aimed at the efficient management of water resources. It is concluded that cartography is a fundamental tool for identifying priority intervention areas, contributing to more effective territorial planning in addressing water insecurity
