Why is agrobiodiversity important for agriculture?

• A. It reduces crop yields
• B. It supports resilience, nutrition, and adaptation to climate variability
• C. It decreases ecosystem services
• D. It increases pesticide dependency

Answer: (B)

Agrobiodiversity boosts resilience, nutrition, and climate adaptability in farming. By keeping a variety of crops, livestock, and genetic resources, farming systems can endure and recover from diverse stresses—droughts, floods, pests, and diseases—because some components will perform well even when others struggle. This diversity also expands the range of nutrients available to people, since a mix of crops provides a broader spectrum of vitamins, minerals, and other beneficial compounds. In addition, diverse varieties and species offer genetic material that breeders can use to develop traits like drought tolerance, heat resistance, and pest resistance, helping farms adapt to changing climate conditions. Diverse systems also support ecosystem services essential to agriculture, such as pollination, natural pest control, soil health, and water regulation, all of which help maintain productivity over time. For these reasons, resilience, nutrition, and adaptation to climate variability describe what makes agrobiodiversity valuable. Some might think diversity lowers yields or increases pesticide reliance, but in reality, it often stabilizes production and reduces the need for inputs by leveraging natural processes and built-in resistance.
