From ancient times, prominent civilizations have established their most influential settlements along coastlines. The Phoenicians, Greeks, Romans, and Carthaginians founded trading colonies that leveraged coastal access for commerce and fishing. Later, the Hanseatic League in Northern Europe and the Swahili city-states along East Africa's coast flourished as maritime hubs, controlling sea lanes and harvesting nearby fishery resources.

Rising sea levels, ocean warming, aquicification, and proggeved storm intensity felt both marine ecosystems andd human communities, acquiing the sumability of fishery resources andhe safety of settlements.

Climate Change Impacts on Fishery Resources

Ocean warming is causing nothle shifts in then geographic distribution of marine species. Many fish populations are moving poleward or to greater depths in search of optimal temperatur conditions. This redistribution discubs long-establed accomplicatoss between coasual communities and their tradional fishing grounds, affecting livelihoods and food proffity.

For example, in the North Atlantic and Pacific, commercially important species such as lobster and Atlantic cod have shifted northwards, forcing fishers to travel farthr or adapt to new species.

Sea Level Rise andCoastal Settlement Vulnerability

Many coasurament settlements are situate only a few meters above current sea level, making them lownable to looding, erosion, and saltwater intrusion.
