Question 1

Kerala's agricultural landscape has undergone a significant transformation, with a historical shift from subsistence food crops to commercial cash crops like rubber, coconut, and spices. What is a major long-term economic consequence of this specialization for the state's agriculture sector?

Accepted Answer

B. Increased vulnerability of farmer incomes to global commodity price fluctuations and external market forces. — The specialization in cash crops makes Kerala's agricultural economy highly susceptible to global market volatility. Fluctuations in international prices for commodities like rubber or spices directly impact farmer incomes, leading to economic instability and risk. While export earnings can facilitate food imports, the inherent dependency on external markets poses a significant long-term economic vulnerability rather than enhancing overall food security or promoting land consolidation.

Answer

A. Enhanced food security through increased export earnings, enabling the import of necessary food grains.

Answer

C. Significant reduction in land fragmentation due to consolidation of holdings for large-scale commercial farming.

Answer

D. Greater self-sufficiency in fodder and feed production for livestock due to diversified cropping patterns.
