SIG participativo para la gestión ambiental de zonas contaminadas por residuos sólidos en la UPZ Galerías, Bogotá D.C. (Colombia)

Abstract

The amount of municipal solid waste (MSW) has increased steadily in the last decade due to population growth and the rate of waste generation; if they are not managed properly, it can involve high costs and hinder the environmental management of them. Current trends seek new collection and transport systems that are technically viable, environmentally efficient and economically sustainable, and in many cases rely on geospatial technologies. In this study, the Geographic Information Systems (GIS) tools were used to design a GIS web application to identify areas contaminated by solid waste through participatory GIS in the UPZ Galerias, Bogotá city (Colombia). The needs of collaborative geographic information were identified, a prototype of a technological solution was developed and then a heat map service was generated in real time. The results reported that the identification of the basic needs of geospatial information is fundamental, since it allows the use of base information as a starting point. The use of GIS tools such as ArcGIS Desktop, ArcGIS Online, Collector for ArcGIS and web Appbuilder for ArcGIS, allowed efficient work. Likewise, heat maps based on collaborative geographic information facilitated the visualization of the areas with the highest contamination density. Finally, the development of GIS web applications can help to carry out a more efficient management of the contaminated areas and take control and prevention measures at the level of the local administration, the service provider company and the citizens.
