A buffer zone in an environmental context refers to an area strategically established to minimize the impact of adjacent land uses on a sensitive ecological area. This means that buffer zones are typically located alongside natural resources such as rivers, wetlands, and forests. They serve several critical functions, including reducing the runoff of pollutants, providing habitat for wildlife, and maintaining the ecological integrity of sensitive areas by acting as a transitional space between developed land and natural habitats.

By dissipating the effects of human activities, buffer zones help maintain biodiversity and protect ecosystems from disturbances such as erosion, chemical runoff, and invasive species. Their design often considers factors such as width, vegetation type, and water flow dynamics to enhance their protective functions effectively.

While areas designed to enhance wildlife habitat, those completely free from human influence, and areas used for recreational activities are important concepts in environmental management, they do not specifically embody the primary purpose of a buffer zone, which is to mitigate impacts from adjacent land uses.
