Much of the world's population, economic activities and critical infrastructure are concentrated near the sea , with nearly 11% of the global population, or 896 million people, already living on low-lying coasts directly exposed to interacting climatic and non-climatic coastal hazards . Low-lying cities and settlements  by the sea are experiencing adverse climate impacts that are superimposed on extensive and accelerating anthropogenic coastal change . Depending on coastal C&S characteristics, continuing existing patterns of coastal development will worsen exposure and vulnerability . With accelerating sea level rise  and worsening climate-driven risks in a warming world, prospects for achieving the Sustainable Development Goals  and charting climate resilient development  pathways are dismal . However, coastal C&S are also the source of SDG and CRD solutions, because they are centres of innovation with long histories of place-based livelihoods, many of which are globally connected through maritime trade and exchange  .
