The Coastal Sensitivity Index (CSI) provides a snapshot of the potential sensitivity of the New Zealand soft shore coastline to coastal inundation (coastal flooding) and coastal change (erosion and accretion) due to future climate change. The Coastal Sensitivity Index was developed as part of the Coastal Adaptation to Climate Change (CACC) project. This four-year project funded by the Ministry of Business, Innovation & Employment (MBIE contract C0X0802) was intended to create the necessary information and tools to enable adaptation by central and local government and communities to the impacts of climate-induced change on the coastal environment
