Satellite-based precision agriculture

In West Africa, agriculture employs a major share of the population yet remains vulnerable: water stress, pests, climate variability. Decisions — irrigation, fertilisation, harvest timing — are often made without objective data on the real state of plots scattered across vast, hard-to-reach territories.

For crop insurers and development funders, the lack of reliable yield and loss measurement complicates pricing, claims and aid targeting. What is missing is a way to track crop health and productivity at large scale and low cost.

ADST leverages free, recurring satellite imagery — notably Sentinel-2 — to monitor crops plot by plot. We compute vegetation indices (NDVI, EVI, water-stress indices) and track their evolution over time to detect anomalies early: stress, disease, growth delays.

By cross-referencing these image time series with weather and soil data, we train yield-forecasting models that estimate expected production well before harvest, at both plot and regional scale.

These indicators power concrete use cases: agronomic alerts for producers, index insurance automatically triggered in case of drought, impact monitoring for development programmes, and mapping of cultivated areas for public policy.
