Evaluating Coastal Resilience in Punta Soldado, Colombia

September 24, 2019
Beaches and tidal planes are replaced by the old mangrove forest soils that try to resist wave actions. These areas formerly constituted as shorebird habitat, today they are disappearing.

The Project “Evaluation of coastal resilience of Punta Soldado, Colombia under scenarios of variability and climate change” has been able to integrate the local community, regional government agencies and academia to work together in the creation of a climate adaption plan. This plan will benefit the community and migratory shorebird populations facing scenarios of variability and climate change. Recently, we have been planning field campaigns in close coordination with national researchers to calibrate numerical models that describe coastal currents and therefore study the changes that these ecosystems will suffer. Afterwards, we will develop the recommendations and adaptation strategies for the protection of habitats and environmental services, which will be analyzed and agreed upon with the community and local governments.
