Coastal defense refers to the strategies and structures used to protect coastlines from erosion, flooding, and storm damage. This can include natural solutions like restoring wetlands and dunes, as well as man-made structures such as sea walls, breakwaters, and groins. These measures help to absorb wave energy and reduce the impact of storms on coastal communities. Effective coastal defense is essential for safeguarding infrastructure, ecosystems, and human lives in coastal areas. As climate change leads to rising sea levels and increased storm intensity, many regions are investing in improved coastal defense systems to enhance resilience and protect valuable habitats like mangroves and coral reefs.
