Project description

EO-ALLert “Early-Warning to the Impacts of Alluvial Mining on Sensitive Areas Using Earth Observation” aims to provide the means for development agencies and authorities to identify priority areas to be preserved from the impacts of alluvial small-scale mining. It considers the case of alluvial gold mining in El-Bagre, Colombia and works on integrating information from satellite data and stakeholder priorities. This results in scientifically and geo-spatially based understanding of mining activities and their impacts. Though the study site is in Colombia, the applications of this project are not limited to this country and will contribute to the development of new approaches to monitor and assess small-scale mining worldwide. The project’s expected impacts are related to several of the United Nations Agenda 2030 for Sustainable Development Goals (SDGs) (Nations, 2019) including SDG1 (End Poverty), SDG3 (Good Health and Well-Being), SDG6 (Clean water and Sanitation), SDG8 (Decent Work and Economic Growth), SDG12 (Responsible Consumption and Production), SDG15 (Life on Land), and SDG16 (Peace and Justice; Strong Institutions)
