Delimitación de áreas con riesgo de erosión del suelo como herramienta para la implementación de técnicas agroecológicas para su recuperación en la comunidad Babarcote, Biblián – Cañar

Abstract

Currently, in the Development Plan and Territorial Planning (PDOT) of Biblián, areas of soil erosion can be visualized using only cartographic information of slopes and soil coverage of the year 2018. This methodology can be improved for planning and accurate decision making. In this project, procedures are applied to identify areas at risk of soil erosion using three variables: a) contour mapping, b) soil depth and c) soil coverage. With updated and relevant data, the stated objective is to obtain thematic maps to mark these areas. With the mapping software ArcGIS, the cartographic layers were edited to mark the areas at risk of erosion and generate maps in which these areas can be visualized. The areas were categorized in a range between 1 and 10, with 1 being the highest risk value and 10 the lowest. The combination of the three digital files resulted in a map of areas with higher risk of erosion, where a total of 419.37 hectares with high vulnerability to erosion were calculated in areas where conventional agricultural and livestock production systems are being implemented, which represents 77.80% of the community’s territory and with this use this tool as a basis for the implementation of agroecological techniques for soil recovery in the Babarcote community of Biblián in the province of Cañar.
