Question 1

Kerala's agricultural sector is characterized by fragmented landholdings, vulnerability to climate change, and challenges in post-harvest management, especially for small and marginal farmers. To enhance the resilience and profitability of these farmers by integrating them into the agricultural value chain and mitigating risks, which intervention would be *most effective*?

Accepted Answer

B. Strengthening Farmer Producer Organizations (FPOs) for collective bargaining, input procurement, processing, and direct market linkages. — Farmer Producer Organizations (FPOs) enable small and marginal farmers to aggregate their produce, inputs, and bargaining power, effectively overcoming the disadvantages of fragmented landholdings. This collective approach facilitates better access to quality inputs, post-harvest processing facilities, and direct market linkages, thereby integrating them into the agricultural value chain and enhancing their resilience and profitability. While other options offer some benefits, FPOs provide a more comprehensive solution for value chain integration and holistic risk mitigation for small farmers.
