Identificación de pasivos ambientales por la actividad minera de áridos y pétreos en el cantón Machala

Abstract

This research focuses on the problem of the lack of identification of environmental liabilities, specifically those generated by the mining of aggregates and stones. Proper identification of these liabilities is crucial to recognize the environmental impacts caused and to effectively contribute to the environmental recovery of the area. The study aimed to identify and evaluate the environmental liabilities present in mining areas. To achieve this, three methods were applied: the theoretical-documentary method, which allowed for a review of relevant backgrounds and concepts; the observation method, through the use of an environmental assessment form for the characterization of the liabilities; and the empirical method, which used an importance matrix to qualitatively assess the identified impacts. As a result of a thorough visual inspection of the site, two main environmental liabilities were identified: the presence of abandoned machinery and oil and fuel stains on the ground. These findings highlight the need to implement corrective measures and continuous monitoring to mitigate the negative effects of mining activities on the environment.
