What is the significance of establishing buffer zones around water bodies?

Establishing buffer zones around water bodies is crucial for filtering runoff and protecting aquatic ecosystems from pesticide exposure. These buffer zones typically consist of natural vegetation that helps to absorb and filter out chemicals and pollutants before they enter the water. This process significantly reduces the amount of harmful substances, such as pesticides and fertilizers, that can contaminate aquatic habitats, thereby supporting the health of fish, plants, and other wildlife in these ecosystems.

Buffer zones also provide a transition area that can enhance water quality by stabilizing the soil and reducing erosion, which further protects water quality. This natural barrier not only improves the health of aquatic life but also maintains the overall balance of the ecosystem within and around the water body.
