Lessons learnt and best practices of managing coastal risk from local communities’ perspectives: technical report.
The coast forms a dynamic, interface zone where the land and sea realms meet and is characterised by some of the world’s most sensitive ecosystems, such as mangroves, wetlands, coral reefs, dunes and beaches. Unlike watersheds, coastal areas have no natural, clear nor precise boundaries. They are subjected continuously to the natural processes of weathering, coastal erosion, coastal flooding and sea-level rise. The impacts of these processes and events vary from one coastal zone to another depending on the geology and geomorphology of the coast and its exposure to natural processes. As the interface between land and sea, coastal areas perform many essential functions like natural protection against storms, regulation of water exchange between land and sea, regulation of the chemical composition of sediments and water, storage and recycling of nutrients and maintenance of biological and genetic diversity. From socio-economic perspectives, coastal zones are important settlement areas which play a critical role in the wealth creation of many nations as they offer access to fisheries and commerce, proximity to rich agricultural lowlands, aesthetic landscapes as well as cultural and recreational opportunities.
