Figure CCP2.4 | Generic adaptation pathways for coastal cities and settlements (a) and the typical solution space, with illustrative pathways for three coastal archetypes (b). As risk increases under rising sea levels, solutions need to be combined or sequenced in order to contain risk. Pathways involve different trade-offs. Based on Tables SMCCP2.1–2.3; Chapters 11 and 13; Magnan and Duvat (2020); Lawrence et al. (2020); Haasnoot et al. (2019). Depending on local conditions, archetype and risk tolerance, alternative pathways are needed and possible to contain risk. Dashed lines indicate uncertainty in the pathway (a); dashed and plain borders are used for illustrating various local situations within each archetype (b).
