Environmental data is most useful when it reflects local conditions and reaches people in time to act. In Mexico, Bolivia and Guatemala, community organisations are collecting and interpreting data themselves. Their monitoring supports decisions about fishing, agricultural burning and crop protection.
In Punta Allen, Mexico, the community-run monitoring centre CECIMS uses hydrophones to listen for Caribbean grouper spawning aggregations. The acoustic data helps residents identify when and where the fish reproduce, supporting decisions about fishing refuge zones during spawning periods. The recordings also contribute to longer-term monitoring of changing marine conditions.
In Bolivia’s Chiquitano forest, the Peniel Community built a weather station and a colour-coded wooden board that residents consult each morning. The board translates temperature, humidity and wind readings into guidance on whether conditions are suitable for agricultural burning. It gives farmers a locally managed process for reducing the risk of an uncontrolled fire.
In Totonicapán, Guatemala, CDRO trains young Indigenous K’iche’ residents as climate promoters. They interpret weather-station data and turn it into accessible bulletins about frost, drought and extreme temperatures. The information reaches farming communities through people who understand the local language, conditions and agricultural practices.
