Protecting the small island nation of Tuvalu from the impact of rising sea level and increasing cyclone events that threaten the country’s viability.

Tuvalu is the fourth smallest nation in the world, comprising nine inhabited islands with a population of 10,640. With an average elevation of only 1.83m. It is one of the most vulnerable countries in the world to the impacts of climate change. The combination of two manifestations of climate change – continually intensifying cyclone events and sea level rise – threaten to have dire impacts on Tuvalu. In 2015 Cyclone Pam displaced 45% of the population.

The project will build coastal resilience in three of Tuvalu’s nine inhabited islands, managing coastal inundation risks. 2,780m of high-value vulnerable coastline will be protected, reducing the impact of increasingly intensive wave action on key infrastructure. The investments will build upon existing initiatives, using a range of measures for coastal protection including eco-system initiatives, beach nourishment, concrete and rock revetments, and sea walls. National capacity for resilient coastal management will also be developed, and the project will help to catalyse additional coastal adaptation finance from other donors.

The project has an estimated lifespan of 40 years.

Tuvalu: Gathering the data to climate-proof coastal infrastructure investments

30 Nov 2021 / The Tuvalu Coastal Adaptation Project (TCAP) is helping the Pacific atoll nation of Tuvalu to develop a long-term coastal adaptation strategy. This Green Climate Fund project, implemented by UNDP, is using airborne LIDAR, a state-of-the-art airplane-mounted technology, to collect precise information on land surface height and seafloor depth. The data will help model future climate-impact scenarios, allowing better planning of coastal infrastructure investments to protect vulnerable communities.
