Avaliação da capacidade do uso do solo em potencial área de recarga de nascentes da microbacia do rio charneca, Caém/Saúde-Bahia

Abstract

The objective of this work was to identify the land use capacity in a spring recharge zone, in the Charneca River Watershed, in the municipalities of Caém and Saúde, Bahia. The Microbasin is located in Serra das Jacobinas, a region that has a sub-humid microclimate, but is located within the semiarid region. It was possible to raise that the agricultural treatments applied by families, even if in a rudimentary way, have been the actions that have contributed most to change this space. Agricultural practices applied in recharge areas are rudimentary, so individuals resort to manual labor, as well as fire, to suppress vegetation and develop their activities. The relief is mountainous, with an outcrop of the Jacobina Group and adjacent to the Health Complex. The rocks are predominantly metamorphic, with emphasis on quartzites and orthoquartzites. The genesis of the relief contributes to the formation of steep slopes of the slopes. Maps of land use capacity were generated, from the source recharge zone, showing that more than half of the areas were altered through agricultural practices, so that another tract was identified, with the presence of seasonal forest, which can be used for permanent crops or preservation of flora and fauna.
