SPOTGALAMSEY

AI-Powered Environmental Monitoring

Detecting Illegal Mining from Space

Satellite imagery analysis tracking the destruction of Ghana's land and water resources by illegal mining operations.

The Crisis

Ghana's Environmental Emergency

Illegal mining — known locally as galamsey — has devastated land, poisoned water sources, and endangered millions of lives.

The Problem

A Nation's Resources Under Siege

Galamsey — derived from "gather them and sell" — refers to illegal small-scale gold mining operations that have proliferated across Ghana. These unregulated operations use mercury and other toxic chemicals, devastating ecosystems and contaminating water sources that millions depend on.

Over 60% of Ghana's water bodies are now polluted. Nearly 90,000 hectares of arable land have been irreversibly destroyed. Communities face rising rates of mercury poisoning, birth defects, and waterborne diseases.

SpotGalamsey uses AI-powered satellite imagery analysis to detect and track these operations, providing actionable intelligence to the NAIMOS Taskforce for enforcement action.

Our Approach

How SpotGalamsey Works

We combine satellite technology with artificial intelligence to detect, track, and report illegal mining activity.

01

Detect

AI algorithms analyze satellite imagery from Sentinel-2 and Landsat to identify land disturbance patterns consistent with illegal mining.

02

Verify

Detected sites are cross-referenced with mining permits and verified through multi-temporal analysis and drone surveillance.

03

Report

Verified sites are reported to the NAIMOS Taskforce with detailed coordinates, severity assessments, and environmental impact data.
