Interactive map: this is what the devastation caused by alluvial mining on the Madre de Dios River looks like

Alluvial mining in Madre de Dios not only affects the environment, but also violates fundamental rights of the Indigenous nations that inhabit this part of the country, rich in biodiversity.

An innovative interactive map, developed by the Center for Legal Studies and Social Research (CEJIS), shows how alluvial gold mining impacts the Madre de Dios River, one of the main bodies of water in the Bolivian Amazon and a pillar of life for several Indigenous nations within the Multiethnic Indigenous Territory II (TIM II).

Alluvial gold mining—carried out by barges and dredges that scrape the riverbed and banks—alters the landscape, contaminates the waters, erodes biodiversity, and exposes the Tacana, Ese Ejja, and Kabineño communities to serious environmental and health risks. In this sense, the interactive map published by CEJIS makes it possible to fully understand the scale of these impacts.

What information can be found?

This digital tool allows users to visually and in detail explore the points where gold-mining barges are concentrated, the areas where mining operates inside or outside legally authorized zones, and how these activities overlap with community territories and the waterways that sustain the life and cultural practices of Indigenous peoples.

The interactive map shows the following information in a detailed, comparative, and contextualized way:

  • Geospatial reference: it precisely reveals where extractions are taking place and how close they are to communities and environmentally sensitive areas.
  • Contextualized data: it includes information from a diagnosis prepared by CEJIS together with Indigenous authorities and environmental monitors, detailing the presence of barges, extractive practices, and impacts on Indigenous people’s lives, health, territory, and collective rights.
  • Comparative data: the information makes it possible to observe the expansion of illegal mining activity between 2021 and 2025.

Alluvial mining in Madre de Dios not only affects the environment, but also violates the fundamental rights of the Indigenous nations that inhabit this biodiverse area of the country. Although it is regulated by Bolivian legislation, a large part of the barges operate outside authorized areas, intensifying contamination by mercury and other toxic compounds, as well as the degradation of soils and waterways.
