The primary purpose of a coastal buffer zone is to protect against erosion, preserve biodiversity, and regulate human activity.

A coastal buffer zone is a designated area that provides multiple environmental and protective benefits. It helps protect against erosion by acting as a natural barrier to storm surges and wave action, reducing the impact on coastal infrastructure. Additionally, these zones are crucial for preserving biodiversity by protecting sensitive ecosystems like wetlands, mangroves, and salt marshes. Buffer zones also play a key role in regulating human activity, limiting development and reducing pollution that could harm coastal habitats. These zones are essential for maintaining the health and resilience of coastal ecosystems, ensuring long-term sustainability.
