A more thorough explanation:

A buffer zone is an area of land that separates two different zones or areas to help each blend more easily with the other. It is commonly used in land-use planning to reduce conflicts between different land uses.

For example, a buffer zone can be a strip of land between industrial and residential areas. This strip of land can be used to reduce noise, air pollution, and other negative impacts from the industrial area on the residential area. It can also provide a transition zone between the two areas, making it easier for people to move from one area to the other.

Another example of a buffer zone is a greenbelt. A greenbelt is a strip of land that surrounds a city or town and separates it from the surrounding countryside. It can be used to protect the city from urban sprawl, preserve natural habitats, and provide recreational opportunities for residents.

Overall, buffer zones are important tools for managing land use and reducing conflicts between different land uses. They can help to create more livable communities and protect natural resources.
