Abstract

Beaches have many values to Pacific island communities, for protectionof the land from inundation, as well as community fishing, and tourism attractions.However, beach erosion is prevalent on many coasts, due to both natural andhuman causes. Coastal protection structures such as seawalls are expensive andcan cause negative impacts, such as erosion to adjacent coastlines. Ecosystembasedadaptation integrates biodiversity conservation and ecosystem services, andengages natural ecosystem processes to provide alternative low-cost solutions tobeach erosion. Adapting well-known dune rehabilitation techniques to narrowPacific island beaches, beach ecosystem-based adaptation techniques includebeach access control fencing and gateways, and tree, shrub and ground vine planting.Defined access pathways allow people to access the beach, and facilitate naturalrecovery of trampled vegetation. These beach management tools are incombination with local community capacity building, and engagement in maintenanceand monitoring, which fosters reduction of impacts. Communities uselocally available materials, and traditional expertise in the uses of matting andfencing. Use of beach ecosystem-based adaptation can increase the resilience ofbeaches to climate change and climate variability, and provide alternative softengineeringapproaches that are both low cost and can be effectively applied bylocal communities.
