Some caveats are warranted. First, locating a specific city or settlement in a particular archetype does not account for future reclassification due to growth or shifts in development trajectories. Second, significant socioeconomic, political and governance variations exist within many C&S, such as impoverished informal settlements alongside wealthy neighbourhoods in cities like Cape Town and São Paulo . Third, this archetype framework does not explicitly reveal important interconnections between coastal C&S and their hinterlands, or between particular C&S through maritime trade or other economic, sociocultural and geopolitical interdependencies. Notwithstanding these caveats, these archetypes reveal differentiated physical impacts and socioeconomic conditions, as well as the variable challenges and opportunities arising when addressing climate change impacts and projected risk, which, depending on coastal type, C&S size and resource availability, help to inform efforts to adapt and chart CRD for each archetype .
