They can be set up for a multitude of reasons, such as to prevent violence, protect the environment, shield residential and commercial zones from industrial accidents or natural disasters, or even isolate prisons.
Buffer zones often result in large uninhabited regions that are themselves noteworthy in many increasingly developed or crowded parts of the world that unintentionally create a de facto wildlife sanctuary.
[example needed] For use in nature conservation, a buffer zone is often created to enhance the protection of areas under management for their biodiversity importance.
[3] The importance and function of a buffer zone and the necessary protective measures derived thereof is a relatively new concept in conservation science and can differ greatly for each site.
Because farmland is sprayed with large amounts of pesticides, some of which can seep into surface water, fish and other aquatic life can be negatively affected, which in turn can lead to environmental damage.
The adsorption capacity of a buffer zone can reduce the speed of surface runoff and increase the effective water content of soil.
[8] Because of their ability to provide abundant water, soft soil and stable climate, small animals such as Myotis and Martes prefer to live along riverbanks rather than in hilly areas.
In addition, some recreational facilities can be built in the buffer zone to provide better living conditions for residents or tourists and improve people's quality of life.
