Coastal erosion is one of the most urgent climate challenges Colombia’s Caribbean coast is facing. To support better decision-making, the International Panel on Deltas and Coastal Areas (IPDC) is developing a large-scale coastal morphodynamics analysis that helps identify erosion hotspots, quantify the expected erosion under future scenarios, and prioritise adaptation measures. By combining advanced modelling, open data, and local engagement, this initiative provides actionable insights for policymakers, practitioners, and coastal communities across the region.
Coastal erosion in the Colombian Caribbean is already affecting ecosystems, infrastructure, and livelihoods, yet decision-makers often lack integrated, region-wide information to act effectively. Many existing approaches focus on isolated sites and short-term measures, limiting their usefulness for long-term planning and climate adaptation.
To address this gap, IPDC is supporting the development of a large-scale coastal morphodynamics model for the southern Colombian Caribbean, including the departments Sucre, Chocó, Bolívar, Córdoba and Antioquia. The approach combines numerical shoreline modelling with climate and oceanographic data to analyse erosion patterns over decades, allowing users to explore future scenarios, including sea-level rise and changing wave conditions.
A key strength of this work is its focus on knowledge transfer and accessibility. The model is designed not only as a scientific tool, but also as a practical decision-support instrument. Results will be made publicly available through an online visualisation platform, enabling authorities, researchers, and communities to understand where risks are highest and why.
The project also places strong emphasis on collaborative approaches and joint action. By integrating citizen‑generated data—such as georeferenced coastal photographs—the analysis improves data coverage in remote areas and strengthens local engagement in coastal risk management.
IPDC plays a central role by connecting international expertise with national priorities, strengthening collaboration between Colombian institutions, and academic partners to support evidence-based decision making.
Together, these partners ensure that the results contribute directly to Colombia’s coastal adaptation strategies and the implementation of the Coastal Erosion Master Plan.
