MineWatch uses satellite imagery to detect illegal artisanal gold mining across Ghana's forests — updated every 5 days, covering the nation's most vulnerable regions.
Three stages of intelligent satellite analysis, delivering actionable intelligence every 5 days.
Sentinel-2 multispectral satellite imagery is acquired every 5 days from the European Space Agency's Copernicus programme at 10-30 metre resolution across all monitored regions.
The detection pipeline compares current vegetation levels against 5 historical baseline periods using NDVI change analysis, Hansen forest data and multi-layer masking to identify genuine mining activity.
Verified detections are published to the MineWatch dashboard, giving law enforcement and environmental agencies actionable coordinates for field investigations.
Six primary mining regions currently under continuous satellite surveillance, with national expansion underway.
Ghana loses an estimated $2 billion annually to illegal mining. MineWatch gives environmental defenders the intelligence they need to act faster and more effectively.
The pipeline runs automatically every 5 days, ensuring law enforcement always has the most current intelligence on active galamsey operations.
Multiple masking layers including Hansen forest baseline, settlement exclusion, city buffers and savannah zone restriction minimise false alerts.
Ground-level reports from citizens via the MineWatch mobile app complement satellite data with first-hand evidence from mining areas.
Nine licensed industrial mining operations are automatically excluded, ensuring the platform focuses only on illegal activity.
Access the live detection map, report illegal mining activity and help protect Ghana's forests and rivers for future generations.
