Spatial modeling in the location of a sanitary landfill for the Intag area, Cotacachi canton, Ecuador

Abstract

One of the main problems that contribute to diminish the life quality of Ecuador populations is the inadequate management of the waste, either due to the lack of equipment or programs that contribute to the integral management of waste, this is the case of the current population of INTAG area in Cotacachi canton. Which does not have a sanitary landfill for the final disposal nor management of the solid waste generated. Currently this waste is taken to the Cotacachi´s city landfill, which is in process of definitive closure. This study propose an optimum location of the new sanitary landfill for the INTAG area, the methodology used was maps algebra and spatial modeling through geographic information tools obtaining six location alternatives that were evaluated on field. Then the best option was selected and approved by the Environmental Department of the Municipal GAD of Cotacachi, complying with the specifications of the Environment Ministry of Ecuador. Through the implementation of this study, not only will one of the objectives of the Development Plan of the canton be fulfilled, but also the quality of life of the communities will be substantially improved, reducing the negative environmental impacts that the current conditions generate.
