Coastal adaptation often addresses the risk of flooding and erosion from SLR, changes in storm activity and degradation of coastal ecosystems and their services  . Without coastal protection, people and property will be increasingly exposed to coastal flooding after 2050, especially under RCP8.5 . This section assesses adaptation responses for coastal ecosystems, addressing loss of natural coastal protection , and the need for relocation . Adaptation responses specific to SLR are assessed in detail in Cross-Chapter Box SLR in Chapter 3, while adaptation in coastal cities and settlements is assessed in Chapter 6.
