What does the concept of "buffer zones" aim to protect?

The concept of "buffer zones" primarily aims to protect sensitive environments or non-target species. Buffer zones are defined areas that create a physical barrier between agricultural activities, such as pesticide application, and nearby sensitive areas. This could include water bodies, wildlife habitats, residential areas, or other agricultural fields where different crops might be grown.

The implementation of buffer zones helps to reduce the risk of pesticide drift, which can occur when pesticides are sprayed and are carried by wind or water to unintended areas. This drift can adversely affect non-target species, which include beneficial insects, birds, and aquatic life, leading to ecological imbalances and harm to biodiversity. By maintaining buffer zones, pest control can be achieved while safeguarding these important ecosystems and species.

Other options do not accurately represent the primary purpose of buffer zones. For instance, while farmer safety is crucial, and exposure to chemicals for applicators is minimized through proper practices, this is not the main focus of buffer zones. Similarly, while buffer zones may indirectly assist in protecting crop yields by preventing the negative impacts on beneficial organisms, their primary role is not to address crop yield concerns. Lastly, buffer zones do not protect farm equipment from damage, which is unrelated to the environmental protections they are designed to provide.
