Coastal areas are pristine but unstable largely due to human driven erosion. In early 2015 Cyclone Pam hit the island of Nukufetau causing significant damages to infrastructure and livelihood in the Tuvalu island. Nukufetau is susceptible to severe and longer-lasting coastal erosion, major storms and sea level rise, further exacerbated by climate change. Concrete blocks from the former seawall on the island, serving as high wave protection, were dislodged due to the high wind and severe wave actions of the Cyclone.
This warranted for a proper and long-term management of the coastal shorelines of the remote island. A 500m long and over 3m high replacement seawall was constructed helping Tuvalu prepare for a more hazard-prone future.
