The Caribbean is facing increased threats from climate change, with rising sea levels and extreme weather events endangering local communities and economies. Coral reefs, essential habitats that support nearly 25% of the world’s marine life, act as natural barriers against waves, helping to reduce the intensity of weather impacts. However, these reefs are under severe stress. This project seeks to rehabilitate coral barriers using an innovative green-grey approach to ensure long-term coastal resilience for Andrés Island.
