<p>The objective of the UNDP CBA project is to reduce the vulnerability of communities and the ecosystems upon which they rely to climate change, including increases in climate variability – reducing the impacts of climate change-driven flooding and coastal erosion through improved natural resource management. Increases in flooding, and increases in coastal erosion are separate problems, but with interlinked impacts on communities, and with a multitude of baseline (non-climate) and additional (climate change-driven) drivers. Increases in coastal erosion are driven by increasing intensities of storms, and by declining resilience of buffering coral ecosystems. Increases in flooding largely affect inland access roads leading from the coast road, which pass over marshy lands and are prone to flooding. Inland flooding is driven by a number of baseline factors, including the development of roads without drains or culverts for water passage. However, climate change will increase the vulnerability of these areas to flood, as increasingly intense rainfall events deliver more rainfall in shorter amounts of time. Communities in the region are currently moving inland, away from coastal hazard zones. As they do so, they become more vulnerable to inland flooding, as they become increasingly reliant on inland access roads, which in turn lead to the arterial coast road.</p>
