Small-scale and artisanal mining exist in many parts of the world and produce the majority of worldwide sapphire and about 20% of gold and diamond. While this type of mining provides livelihood to many families in rural areas, it impacts the landscape, degrades the land, and can contaminate the food chain with heavy metals. Thus, the applications of this work are not limited to Colombia. It contributes to the development of new approaches to monitor and assess small-scale mining worldwide. Furthermore, these extractive activities have major implications on several of the United Nations Agenda 2030 for Sustainable Development Goals (SDGs) including the following ones:
EO-ALLert: Early-Warning to the Impacts of Alluvial Mining on Sensitive Areas Using Earth Observation
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 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.
