Crop diversity refers to the variety of different crops grown in a specific area or region. This includes various species and varieties of plants, such as wheat, rice, corn, and vegetables. High crop diversity can enhance food security by providing a range of nutrients and reducing the risk of crop failure due to pests, diseases, or climate change. Maintaining crop diversity is essential for sustainable agriculture. It helps improve soil health, supports biodiversity, and can lead to better yields over time. Farmers often practice crop rotation and intercropping to promote diversity, which can also benefit local ecosystems and wildlife.
