Análisis de servicios ecosistémicos ambientales de abastecimiento en comunidades de la zona alta de la parroquia San Juan para el diseño de un modelo de economía circular

Abstract

The objective of this study was to analyze the environmental ecosystem services of supply in the Chorrera-Mirador community and the Pulingui, San Pablo association in the upper area of the San Juan parish for the design of a circular economy model of the most important ecosystem services: fresh water and raw material (alpaca wool), on which they focus their activities. The analysis was based on observation and an informal semi-structured interview with the key actors and inhabitants of the study places. The percentage of circularity for the two supply ecosystem services was determined; for freshwater, the World Business Council for Sustainable Development (WBCSD) methodology was used, and the Ellen MacArthur methodology was used for the raw material. In both calculations, a result of 0% of circularity. The choice experiment method without market value was used with three response alternatives to choose the best circular economy model. It was found that the best option for the community and the association is the model based on the DISRUPT framework with high acceptance (77%). Therefore, it is recommended that, once the proposed circular economy model has been implemented, a second calculation of the circularity percentage of the two main supply environmental ecosystem services (freshwater and raw material) can be made to determine their efficiency
