Fragilidade ambiental e escassez hídrica em bacias hidrográficas: Manancial do Rio das Araras - Araras, SP./ Environmental Fragility and water scarcity in catchment basins: Headwaters of Araras River - Araras, SP.

Abstract: Estudos envolvendo bacias hidrográficas raramente abordam os impactos gerados pelas atividades humanas em bacias utilizadas como mananciais de abastecimento. As ações humanas relacionadas à urbanização, industrialização e agropecuária, sem o planejamento adequado, são as que mais comprometem os serviços ambientais em tais bacias.

“…Although the occurrence of sugarcane cooperates with a lower soil infiltration capacity, due to the compaction caused by the use of agricultural machinery, as verified by Costa et al (2015b), the contamination potential is also considered the most important attribute for this analysis. This fact is due to the large amounts of agrochemicals used during the cultivation process (PALMA et al, 2015).…”

“…A metodologia aplicada foi adaptada da proposta por Ross (1994Ross ( , 2012, em que informações a respeito dos componentes físicos, biológicos e sociais de um ambiente são representadas em Planos de Informação (PI's) e sobrepostas em um processo de análise multicritério. O resultado desse processo é um mapa de fragilidade ambiental, que serve de auxílio para que as intervenções humanas aproveitem as potencialidades locais e respeitem suas limitações de uso (Ross, 1994;Kawakubo et al, 2005;Costa et al, 2015).…”

“…Studies by Zuquette et al (2006) in neighboring river basins with the same physical characteristics showed that instead of having homogeneous soils, percolation and surface runoff rates depend on soil use and management practices. According to Costa et al (2015), in 2014 the city of Araras (SP) underwent an unusual scenario with the emptying of the main surface water collection sources and a loss of resilience after a period of drought. Such conditions were also felt in all southeast regions of the country, with conditions so severe in the state of São Paulo that decision makers were forced to adopt extreme measures such as compulsory water rationing.…”
