Coastal protection refers to strategies and measures taken to safeguard coastlines from erosion, flooding, and other environmental threats. This can include the construction of structures like sea walls, breakwaters, and dunes, which help absorb wave energy and reduce the impact of storms. Additionally, coastal protection can involve natural solutions, such as restoring mangroves and wetlands, which act as buffers against rising sea levels and storm surges. These methods not only protect human settlements but also preserve vital ecosystems that support diverse wildlife and plant species.
