Nature-Based Solutions for Coastal Resilience - Opportunities in Dominica, Grenada, St. Lucia, and St. Vincent and the Grenadines

Jul 19, 2026

Upload by Eliana

This report, prepared for the World Bank’s global program on Nature-Based Solutions for Coastal Resilience and supported by PROBLUE, analyzes how nature-based solutions can reduce climate and coastal flood risks in Dominica, Grenada, St. Lucia, and St. Vincent and the Grenadines. It combines geospatial information, flood modeling, and scenario-based analyses to define NBS typologies, map suitability, and identify priority intervention strategies. The study quantifies flood-risk reduction, evaluates additional co-benefits such as fisheries and tourism, and conducts cost-benefit analysis to support coastal climate adaptation decisions.

FAQs

What problem does the report address regarding coastal resilience in the Eastern Caribbean?

The report addresses rising coastal flooding risks driven by climate change and the degradation of coastal habitats, which can intensify inundation impacts. It focuses on how to mitigate these risks through nature-based approaches.

How does the report define Nature-Based Solutions (NBS) for this study?

NBS are defined as actions that protect, conserve, restore, and/or sustainably manage coastal ecosystems to mitigate climate risks. The report also considers co-benefits such as fisheries and tourism enhancement and carbon sequestration.

What methods are used to identify and evaluate NBS opportunities?

The report uses geospatial information, flood modeling, and scenario-based analyses. It builds suitability mapping and criteria for NBS identification, then quantifies benefits, co-benefits, and costs through cost-benefit analysis.
