Madre de Dios, Peru is home to multiple protected areas, such as Manú National Park, Tambopata National Reserve, and Amarakaeri Communal Reserve. Artisanal and small-scale gold mining (ASGM) is increasingly common in this region and ASGM activities have recently been identified in protected lands. Land use and land cover change analysis is a key requirement for environmental management. The goal of this study is to predict land cover changes in Madre de Dios in relation to ASGM in order to inform sustainable use of resources and plan effectively for environmental protection. This study used random forest classification to map mining area from Landsat imagery. An integrated multi-layer perceptron-Markov chain analysis was used to predict future land use and land cover changes in Madre de Dios, with specific attention given to mining. Gains in mining area in this highly biodiverse region are expected to continue and protected areas could be affected. In an area experiencing increasing anthropogenic pressure, results have the potential to significantly contribute to future management decisions.
