The lagoon system Carmen-Pajonal-Machona is located in the Gulf of Mexico and has an area of 190 km2. Anthropogenic change, mainly due to oil extraction, has changed the hydrodynamic, morphological and ecological characteristics of the lagoon system. Other causes of alteration are: agricultural development, deforestation and industrial development. In addition to these problems, which already make the system vulnerable, there are further problems due to the impact of climate change. The project aims at designing adaptation measures to climate change, which will be managed by local communities.
