coastlinedominated

Coastlinedominated is a term used in geography and regional planning to describe regions, systems, or landscapes in which coastal processes and the interaction with the sea exert primary influence over land use, economy, demographics, and hazard profiles. The word emphasizes that the coastline, rather than inland areas, largely shapes dynamics and outcomes in the area being described.

In practice, coastlinedominated areas typically show a high concentration of population and economic activity within a narrow coastal belt, substantial reliance on maritime industries such as fishing, shipping, and tourism, and strong ecological and cultural links to coastal ecosystems like beaches, deltas, estuaries, and mangroves. They also exhibit pronounced land–sea interactions, including sediment transport, tidal influence, and exposure to sea-level rise and storms. Indicators may include the share of population or GDP within a defined coastal zone, the density of coastally oriented infrastructure, and the extent of coastal ecosystems in land cover.

Applications of the concept include regional planning and risk assessment, where identifying coastlinedominated areas helps prioritize coastal adaptation, zoning, infrastructure resilience, and conservation of coastal habitats. The term supports comparative analysis between regions where maritime dynamics are central to livelihoods and those that are more inland or interior.

Limitations include its broad and sometimes subjective nature; boundaries depend on chosen thresholds, and the concept can overlap with existing terms such as littoral regions and coastal zones. See also: littoral zone, coastal geography, coastal management, delta regions, maritime economy.
