Análisis de la calidad y usos del agua en la minicuenca hidrográfica de la quebrada San Francisco- microcuenca del río Malacatos y la importancia de los sistemas agroforestales.

Abstract

The watersheds are subject to anthropogenic impacts, which contributes to environmental problems such as the deterioration of water quality. As a result, several authors suggest that agroforestry systems (SAFs) must be implemented to solve these problems. The work is based on the morphometric characterization to understand the hydrological functioning of the mini-basin, flow analysis, water quality indexes and land uses of the minicube, and the effects that SAFs may have on them. The results show that water quality varies from good to bad. The points that register poor quality of water have physical-chemical parameters above the permitted limits, less abundance of benthic organisms and soils with pastures. The points with good water quality are characterized because the indicated parameters meet the established limits, they have abundance of benthic organisms, natural forest soils and temporary crops (coffee-SAFs). With which it is concluded that the use of land and SAFs contribute to maintain a good quality and quantity of water.
