Pesticide Use Risk Map (2023)
This layer rates the biodiversity risk posed by pesticide use in each country, based on how much pesticide is applied per hectare of agricultural land.

What it shows
This layer rates the biodiversity risk posed by pesticide use in each country, based on how much pesticide is applied per hectare of agricultural land. Intensive pesticide use is a recognised pressure on biodiversity — affecting pollinators, soil life and freshwater ecosystems — so the map helps identify where agricultural inputs may threaten nature.
How it is built
The underlying variable is national pesticide application intensity (quantity used per hectare of agricultural land) for the year 2023, drawn from the Food and Agriculture Organization (FAO). Each of the 197 countries is assigned to one of five risk categories using classification thresholds defined by the WWF Biodiversity Risk Filter methodology. Because it is reported at the country level, the entire territory of a country carries a single risk class.
How to read it
Countries are graded into five classes from very low (green) to very high (dark red). A higher class means more intensive pesticide use per hectare and therefore greater potential pressure on biodiversity. A site is assessed according to the class of the country it falls within, so this is a broad national signal rather than a local measurement.

Comparison with the WWF Risk Filter Suite
This layer corresponds to BRF S13_4 Pollution. It is built on the same FAO inputs and WWF classification thresholds, so it is closely aligned with the WWF methodology. Darwin also offers finer gridded pollution risk maps elsewhere; this country-level pesticide map matches WWF's national resolution directly.
Risk analysis
A site is flagged on a dimension by combining a proximity trigger (this layer) with an activity trigger (the entity's ENCORE pressure/service). Proximity only → Potentially material; proximity and the matching ENCORE pressure/service is material → Very material; neither → Not material.
| Dimension | ENCORE service / pressure | Proximity trigger (this layer) | Activity trigger (entity) |
|---|---|---|---|
| Pollution | Emissions of toxic soil and water pollutants | Layer value above 3 | “Emissions of toxic soil and water pollutants” pressure ≥ 4 |
