WWF and Wageningen University's Forest Foresight uses Sentinel-1 radar and ML to flag illegal-logging and mining risk months ahead. Gabonese rangers acted on an alert to halt an illegal gold-mining operation, saving about 30 hectares of forest and leading to arrests.

Forest Foresight combines Sentinel-1 radar imagery (via the RADD system) with a machine-learning model trained on patterns that typically precede illegal logging, mining and agricultural clearing, flagging high-risk forest areas up to six months before clearing happens. In Gabon it is jointly run by WWF, Wageningen University & Research and Gabon's Ministry of Water and Forest Affairs, with Cameroon's MINFOF as a partner in the wider Congo Basin pilot; the initiative was presented at COP28 in 2023.
Objectives
The tool aims to give rangers and authorities an early warning window to intervene before illegal clearing occurs, rather than only detecting it after the fact, and ultimately to extend predictive monitoring to 15 landscapes across 12 countries by 2027.
Activities
Radar and ML-based alerts are generated for at-risk forest areas and passed to park rangers and authorities; the approach is piloted concurrently in Gabon, Kalimantan (Indonesia) and Suriname.
Results
In one documented case, an alert let Gabonese rangers detect and stop an illegal gold-mining operation, saving an estimated 30 hectares of forest and leading to arrests. Across the Gabon and Kalimantan pilots combined, partners report alerts led to 34 deforestation-prevention actions within a six-month period.
Conclusions
The evidence comes directly from the implementing partners rather than an independent evaluation, and no published accuracy or false-positive rate exists for the prediction model; the division of operational responsibility between the Gabonese government and the NGO/university partners is also not clearly documented, so this is best read as a promising, real, but still NGO-anchored pilot.
Implementation
Indicative cost
Medium (€50k–€500k) — No budget figures are published; classified as medium cost based on the scale of a multi-country satellite-ML monitoring partnership involving two research/NGO bodies and government ministries, presented internationally at COP28.
Time to results
Medium (1–3 years) — Piloted since 2022 with a stated roadmap to scale to 15 landscapes across 12 countries by 2027, indicating a multi-year programme rather than a short pilot cycle.
Staffing & skills
WWF, Wageningen University & Research, Gabon's Ministry of Water and Forest Affairs, Cameroon's Ministry of Forests and Wildlife (MINFOF), partner for the wider Congo Basin pilot
Conditions for success

Rangers and authorities able to act on alerts before clearing occurs
Ongoing government partnership for on-the-ground enforcement
Common failure modes
No published accuracy or false-positive rate for the prediction model
Operational responsibility between government and NGO/university partners not clearly documented
