Overview
- Nearly one in four school sites are classified under strong pressure within a 1,000‑metre radius, covering about 15% of pupils in metropolitan France.
- The mapping combines crop-level Index of Treatment Frequency from the graphical parcel register with school geolocations from IGN to estimate nearby pesticide use.
- The publishers emphasize that the indicator reflects usage pressure rather than toxicity or health risk and that it is intended to inform public debate.
- Pressure is highest in viticultural basins, cereal plains and fruit‑growing areas, with significantly lower levels in urban settings.
- The strong‑pressure category is illustrated as if each of the roughly 314 hectares around a school received one full‑dose treatment per year, and experts urge more ambitious policies near schools, echoing September findings of higher pesticide biomarkers among vineyard neighbors, especially young children.
