Which principle aligns with agroecology?

• A. Reliance on monocultures.
• B. Centralized decision-making.
• C. Emphasizing biodiversity and reduced external inputs.
• D. Extensive use of synthetic fertilizers.

Answer: (C)

Agroecology focuses on designing farming systems that work with natural ecological processes, emphasizing diverse crops, soil health, and beneficial interactions among organisms. A key principle is to promote biodiversity in the production landscape and rely less on external inputs like synthetic fertilizers and pesticides. This diversity supports natural pest control, improves soil structure and fertility, and increases resilience to pests, weather, and climate variability.

Why this fits best: a system that blends many species, layers of life, and ecological relationships tends to be more sustainable and self-regulating. In contrast, relying on monocultures reduces resilience and increases vulnerability to pests and diseases; centralized decision-making can disconnect farmers from local knowledge and ecological nuances; and heavy use of synthetic fertilizers elevates external inputs and can harm soil health and biodiversity. Hence, the principle that aligns with agroecology is emphasizing biodiversity and reduced external inputs.
