Coastal regions provide some of the most productive and biodiverse environments with an important and often underappreciated carbon storage potential. At the same time, they are among the areas of highest population density, natural assets and cultural heritage in the world, yet are experiencing significant social, economic and environmental challenges, exacerbated by climate change and human pressures.
The REST-COAST project (Large scale RESToration of COASTal ecosystems through rivers to sea connectivity) will demonstrate to what extent upscaled coastal restoration can provide a low-carbon adaptation, reducing risks and providing gains in biodiversity for vulnerable coastal ecosystems, such as wetlands or sea grass beds. By overcoming present technical, economic, governance and social barriers to restoration upscaling, REST-COAST will develop the large scale river-coast connectivity and increase the nearshore accommodation space for the resilient delivery of coastal ecosystem services (ESs). The selected ESs (risk reduction, environmental quality and fish provisioning) touch urgent coastal problems such as the erosion/flooding during recent storms or the accelerating coastal habitat degradation that seriously affects fisheries and aquaculture. Combining new techniques, risk assessments, innovative financial/governance arrangements and homogeneous metrics for ESs and biodiversity, REST-COAST will develop a systemic approach to coastal restoration based on a scalable coastal adaptation plan.
