CAC Sustainability & Conservation — Questions and Answers
Question 1: What is the primary goal of sustainable agriculture?
- Maximizing short-term crop yield
- Balancing environmental health, profitability, and social equity (Correct answer)
- Eliminating organic farming
- Avoiding technological advancements
Correct answer: Balancing environmental health, profitability, and social equity
Sustainable agriculture aims to maintain environmental health, economic profitability, and social equity for future generations.
Question 2: Which farming practice helps reduce soil erosion and maintain soil fertility?
- Mono-cropping
- Cover cropping (Correct answer)

Correct answer: To improve soil health and reduce pests
Crop diversification reduces the risk of pest outbreaks, improves soil health, and increases resilience to climate change.
Question 4: Which conservation method involves planting trees to protect soil from wind erosion?
- Contour farming
- Windbreaks (Correct answer)
- Over-irrigation
- Hydroponic farming
Correct answer: Windbreaks
Windbreaks consist of trees or shrubs planted along farmland to reduce wind erosion and protect soil.
Question 5: Which water conservation technique reduces evaporation and improves moisture retention in soil?
- Flood irrigation
- Mulching (Correct answer)
- Overgrazing
- Deep plowing
Correct answer: Mulching
Mulching helps conserve soil moisture by reducing evaporation and preventing weed growth.
Question 6: What is the main objective of integrated pest management (IPM)?
- To eliminate all pests using chemical pesticides
- To use a combination of sustainable pest control methods (Correct answer)
- To avoid any pest control measures
- To increase pesticide dependency
Correct answer: To use a combination of sustainable pest control methods
Integrated pest management (IPM) combines biological, cultural, mechanical, and chemical methods to control pests sustainably.
