Crop biodiversity preservation focuses on maintaining a variety of plant species and genetic traits crucial for resilient agriculture. Diverse crops ensure adaptability to changing environmental conditions, pests, and diseases. Techniques like seed banks, on-farm conservation, and promoting traditional crop varieties help safeguard biodiversity. Intercropping and agroforestry further enhance genetic diversity in farming systems. Preserving crop biodiversity is essential for food security, cultural heritage, and sustainable agricultural development. It also supports ecosystem services, such as pollination and soil fertility, critical for long-term productivity.
