Further, coastal cities located at higher elevations  or distantly located inland along tidally influenced rivers  also have populations and infrastructure exposed to climate impacts. As such, the inclusion of C&S beyond the LECZ is warranted when assessing climate impacts and associated exposure, vulnerabilities and risks. The coastal zone includes some of the world's largest, most densely populated megacities, as well as the fastest-growing urban areas. However, vast coastal areas are sparsely populated, with populations in these regions concentrated in smaller C&S, including along subsiding shorelines and in deltas . From this wider perspective, climate change impacts on the coast directly or indirectly affect a large portion of the global population, economic activity
