costeras

Costeras is a term used in Spanish to denote coastal regions and features. The plural is used to refer collectively to the coastal zones or to particular coastlines within a region. The concept encompasses both natural landforms and the human settlements and activities associated with the shore.

Geography and geology: Costeras extend from cliffed or rocky shores to sandy beaches, dunes, estuaries, and mangrove swamps. They are shaped by wave energy, tides, sediment transport, and tectonic and isostatic processes. They frequently include transitional zones between land and sea and can vary greatly along short distances.

Ecology: Coastal zones host diverse ecosystems, including breeding sites for seabirds, nurseries for fish, coral reefs in some regions, seagrass beds, and mangroves. They provide important ecological services such as filtration, shoreline protection, and carbon storage.

Human activity: Costeras are hubs of population and economic activity. They host ports, fishing fleets, tourism infrastructure, and residential development. The cultural landscape often reflects coastal livelihoods, cuisine, and traditions.

Challenges: Coastal zones face pressures from erosion, sea level rise, storms, pollution, coastal urbanization, and habitat loss. Climate change intensifies flooding and coastal hazards, while development can reduce natural buffers such as dunes and mangroves.

Management: Integrated coastal zone management aims to balance environmental protection with economic use. Approaches include habitat restoration, beach nourishment, setback zoning, and nature-based solutions. International cooperation and data collection support sustainable management of costeras.
