Análisis espacial multicriterio sobre la vulnerabilidad en las áreas de captación de los sistemas de agua potable del cantón Tisaleo, provincia de Tungurahua.

The availability of water resources is increasingly uncertain, the demand for water is growing and the supply of water is limited by overexploitation and climate change. This leads us to raise several questions: How is the environmental capacity in the Potable Water Catchment Areas (hereinafter ACA) for the generation of drinking water in quantity and quality?, a complicated question that is difficult to answer and that requires, according to the context, environmental, geographical, technical, and local infrastructure, an integrated methodological approach for the construction of indicators or indices that allow an analysis of the sustainability of the ACA, of a particular territory, such as the Tisaleo canton. In this research report, a proposal of indicators is made to evaluate the vulnerabilityof the ACA, for which field activities, Geographic Information System, expert consultation, and Saaty Multicriteria Analysis were applied. The relevance of this methodology helps to constitute and combine different criteria, variables and assumptions to formulate a single evaluation index of the ACA under study. The selection of the indices has been based on the literature review associated with this subject, eight indices are proposed: Land Use Indicator; ACA Size Indicator; Housing Density Indicator; Anthropic Activities Indicator; Water Rights Indicator; Protected Areas Indicator; Precipitation Anomaly Indicator; Protective Vegetal Cover Indicator, which made it possible to evaluate, in an integrated manner, the sustainability of the ACAs in the face of various associated natural and/or physical forcing factors. The results indicate that 33,33% of the analyzed ACAs have medium and high vulnerability.)
