ReDuna São João da Caparica

Almada

One of the consequences of global warming is the sea level rise. In urban settings along coastlines, rising seas threaten not only houses, but also several types of infrastructures such as industries, roads, power plants, freshwater aquifers, etc. Rising sea-level also pushes destructive storm surges further inland, posing very high risks for coastal populations, as storm surges can push water kilometers inland, causing extreme flooding far from the coast. The Portuguese ReDuna project aims to restore the natural capacity of the Almada sand dune-beach ecosystem to healthily respond to natural drivers, enhancing its resilience to sea-level rise and storms. By monitoring in detail the dune ecosystem, the project has been providing scientific and technical knowledge on effective restoration techniques, which provides valuable information for vulnerable coastal areas.

Coastal protection and restoration

Site Presentation

ReDuna is an ambitious dunes restoration project located in São João da Caparica, Portugal, aimed at protecting and restoring the natural dune ecosystems that line this coastal region. This initiative combats coastal erosion by stabilizing the dunes, which act as natural barriers against sea-level rise and storm impacts, preserving local biodiversity and protecting inland areas. The project employs native vegetation planting and sand-trapping techniques, which help to rebuild the natural structure of the dunes, thereby supporting a resilient ecosystem. ReDuna also involves local communities through educational programs, raising awareness about the importance of dunes for coastal resilience and biodiversity.
