Which statement best describes agroecological tools for sustainable farming among crop rotation, intercropping, and agroforestry?

• A. Crop rotation increases pest pressure.
• B. Intercropping reduces biodiversity.
• C. Crop rotation increases pest pressure.
• D. Agroforestry places trees with crops for shade, carbon storage, and soil stabilization.

Answer: (D)

Agroecological tools are practices that work with natural processes to make farming more sustainable, boosting soil health, biodiversity, and resilience. Among these, agroforestry stands out because it combines trees with crops to deliver multiple benefits: trees provide shade that can protect crops from heat stress and reduce water loss, they store carbon helping with climate regulation, and their roots and leaf litter help stabilize and enrich soils, reducing erosion and improving structure.

That combination of shading, carbon storage, and soil stabilization is what makes this option the best description of agroforestry’s role in sustainable farming. In contrast, crop rotation is a powerful practice to disrupt pest and disease cycles and improve nutrient balance, but it doesn’t inherently describe the tree-crop integration that defines agroforestry. Intercropping can enhance biodiversity and resource use efficiency, but it doesn’t necessarily involve trees or the specific shade and soil-structure benefits that agroforestry provides.
