Knowra Coastal urbanization Coastal urbanization Coastal urbanization is the growth and concentration of settlements, people, and infrastructure along coastlines. It connects cities and economies to marine resources while increasing exposure to coastal hazards and environmental change.
Coastal land reclamation : The creation of usable land by filling or enclosing shallow coastal waters, wetlands, or tidal flats. Reclamation lets expanding coastal cities add land where inland space is scarce.
Coastal squeeze : The loss of intertidal habitats when rising seas push shorelines landward but built structures block their movement. Shoreline construction can trap habitats between rising water and fixed infrastructure.
Managed retreat : The planned movement of people and assets away from areas exposed to coastal hazards. It is an adaptation option where continued urban protection or rebuilding is unsustainable.
Sea-level rise : The increase in the average level of the global ocean, driven mainly by ocean warming and land-ice loss. Rising seas change the long-term flood and erosion risks facing coastal cities.
Port : A coastal facility where ships load and unload passengers or cargo and may receive other services. Ports attract industry, transport links, and workers that concentrate development on shorelines.
Urban heat island : The tendency for built-up areas to be warmer than nearby less-developed surroundings. Dense coastal construction can intensify local heat alongside the urban climate effect.
Coastal resilience : The capacity of coastal communities and systems to withstand, recover from, and adapt to disturbances. Resilience planning addresses the risks faced by concentrated coastal populations and infrastructure.
Coastal flooding : The inundation of normally dry coastal land by seawater, often during storms or high tides. Flood frequency and depth complicate decisions about future urban expansion and protection.
Coastal migration : The movement of people to, from, or within coastal areas. Migration supplies population growth that can accelerate coastal settlement and urban expansion.
Coastal erosion : The loss or displacement of shoreline material through waves, currents, tides, or wind. Development on eroding shores puts buildings and infrastructure at risk and can prompt hard defenses.
