Africa Mining Watch trains journalists to spot illegal mines from space

Africa Mining Watch trains journalists to spot illegal mines from space

New Capabilities

A Pulitzer Center, Code for Africa and Earth Genome tool brings satellite AI to extractives reporting across the Congo Basin

July 2026: Planned public launch

Overview

Spotting a fresh mining pit in the Congo Basin used to take months of ground reporting and a small fortune in plane tickets. On April 22, about 25 African journalists logged into an online mapathon and learned to find one in minutes, using Sentinel-2 satellite imagery and a machine-learning model trained to recognize the bare-earth scar of an open pit.

The training is the soft launch of Africa Mining Watch, a tool built by the Pulitzer Center, Code for Africa and Earth Genome. A public release is planned for July. The platform copies the playbook of Amazon Mining Watch, which has already fed investigations into illegal gold mining published in Brazil, Spain, Venezuela and the United States.

Why it matters

Reporters covering Congo Basin mining can now see new pits the week they appear, not months later when communities finally complain.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

October 2022

Amazon Mining Watch launch (2022)

Earth Genome, Amazon Conservation and the Pulitzer Center's Rainforest Investigations Network released the first AI-driven public map of gold-mining deforestation across all nine Amazonian countries. The site used a convolutional neural network on Sentinel-2 imagery to flag suspected pits at ten-meter resolution.

Then

Within two years, reporters used the data to publish investigations in Brazil, Spain, Venezuela and the United States, several focused on mining inside Indigenous reserves.

Now

The platform moved to quarterly updates in 2025 and became a standard reference for Amazon environmental coverage, including by Mongabay and MAAP.

Why this matters now

Africa Mining Watch is a direct port of this project with the same lead engineering team. The Amazon timeline is the best guide to what the Africa version is likely to produce and when.

February 2014

Global Forest Watch launch (2014)

The World Resources Institute launched Global Forest Watch with Google, the University of Maryland and about 40 other partners. It put near-real-time deforestation alerts on a public web map, built on Landsat imagery and the Hansen forest-loss dataset.

Then

Within a year, governments in Indonesia and Peru and NGOs in the Congo Basin used the alerts to direct enforcement and reporting. Newsrooms cited the data in dozens of investigations.

Now

Global Forest Watch became permanent reference infrastructure for environmental reporting and accountability, with more than three million users by 2024.

Why this matters now

It is the closest analog for what Africa Mining Watch is trying to be: a public, satellite-driven dataset that both watchdogs and reporters can plug into. Adoption was rapid once the data was free and clickable.

2014 onward

Bellingcat and the rise of open-source satellite reporting (2014 onward)

Eliot Higgins founded Bellingcat in 2014. The team used commercial satellite imagery and social-media geolocation to reconstruct the downing of Malaysia Airlines Flight 17 and later mapped Russian forces in eastern Ukraine and Syria.

Then

Bellingcat investigations were cited by the Dutch Safety Board and the Joint Investigation Team that indicted suspects in the MH17 case.

Now

Open-source intelligence using satellite data became a standard method in investigative journalism, with units at the New York Times, BBC and Reuters.

Why this matters now

Africa Mining Watch tries to do for environmental reporters what Bellingcat did for conflict reporters: turn satellite imagery from a specialist resource into an everyday newsroom tool.
