In this session, we’ll show you how we approached a sensitive topic: mapping the potential exposure of all schools to the use of pesticides from surrounding agricultural activities. We will explain how - working with scientists - we came up with a robust methodology, found the data we needed and then crunched it to tell us where to go to make truly data-driven reporting on the ground.
This investigation, published in Le Monde in December 2025, has sparked a lot of national and local interest thanks to its interactive map. Attendees will leave the session with a clear step-by-step guide to get started and adapt the ambition of the investigation to their own capacity. Feel free to bring with you any datasets that would help to map similar issues in your country.
