WWF runs the Climate Witness programme to collect people's local observations of climate change that are then verified by scientists.
Osvaldo Bonino is a father of 3 and a technical engineer. When the La Picasa lagoon started to expand because of rainfall, in 1997, people thought it was temporary. But the lagoon spread from 10,000 to 30,000 hectares, washing away farms, crops and homes. Many members of the community have had to adapt to the change by switching from farming and agriculture to fishing. For almost seven years, both the national route 7 and the railway have been flooded. Now says Osvaldo, “only the ones who remember us come to Aarón Castellanos”.
Osvaldo spoke at the 10th Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change in Buenos Aires, Argentina, recounting the problem of La Picasa.
