What is agroforestry and how does it contribute to sustainable land use?

• A. An integrated approach combining trees with crops or livestock to enhance biodiversity, soil protection, and productivity.
• B. A farming system that replaces trees with crops to maximize soil loss.
• C. A method of urban landscaping with trees.
• D. A technique for hydroponic tree farming.

Answer: (A)

Agroforestry is an integrated approach that combines trees with crops or livestock on the same land. This setup creates a more diverse and resilient farming system because trees offer benefits like soil protection from erosion, improved organic matter and nutrient cycling, shade and microclimate regulation, and habitat for beneficial species. At the same time, crops or livestock can benefit from the shelter, windbreaks, and additional shade provided by trees, while the system as a whole yields multiple products (timber, fruit, fodder, fuelwood, crops) and spreads risk. All of this supports sustainable land use by maintaining soil health, conserving water, boosting biodiversity, and enhancing long-term productivity.

The other descriptions miss key ideas: replacing trees with crops eliminates the soil protection and biodiversity benefits trees bring; urban landscaping focuses on city environments rather than farmland; hydroponic tree farming involves soil-free growth and isn’t how agroforestry operates.
