Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Among components of sustainability, productivity and ecological viability are more important than economic and social viability.
Reason (R): Because food security depends upon per capita productivity and permanence of productivity depends on ecological base for production.
Choose the correct answer from the options given below:
Show Hint
Permanence of productivity is the core of sustainability. Without an intact ecological foundation (soil, water, climate), economic and social agricultural models cannot exist.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
(A) is true but (R) is false.
(A) is false but (R) is true.

The Correct Option isA
Solution and Explanation
Step 1: Understanding the Concept:
Agricultural sustainability rests on ecological, economic, social, and productive pillars. The ecological foundation is essential for long-term food production. Step 2: Detailed Explanation:
- Assertion analysis: While economic viability and social acceptability are necessary for sustainable agriculture, biophysical productivity and ecological viability are the foundational pillars. If the soil, water, and biological resource base degrades, long-term food production ceases, validating the Assertion.
- Reason analysis: Global food security depends on maintaining per capita food output. This long-term output relies on preserving the ecological base (soil health, water quality, biodiversity). Thus, the Reason is correct and explains why ecological viability and productivity are the most fundamental aspects of sustainability. Step 3: Final Answer:
Both (A) and (R) are true, and (R) is the correct explanation of (A).
