The primary function of biodiversity in agriculture is to provide a robust foundation for food security and ecosystem health. Greater biodiversity enhances the resilience of agricultural systems against pests, diseases, and climate change. It fosters a variety of genetic resources that can improve crop yields and nutritional quality. Biodiversity also supports essential ecosystem services such as soil fertility, pollination, and pest control. By promoting agricultural biodiversity, farmers can create sustainable systems that ensure long-term productivity and ecological balance while safeguarding food resources for future generations.
