UPSC Mains 2021 GS Paper 3 Q14: model answer

What are the present challenges before crop diversification? How do emerging technologies provide an opportunity for crop diversification?

15 marks250 wordsDirective: Answer

What the question wants

Discuss the current challenges to crop diversification and how emerging technologies open opportunities for it.

How to structure it

Challenges, then technology.

  1. Why diversify
  2. Price and market challenges
  3. Farm and input challenges
  4. Technology opportunities
  5. Policy support
  6. Conclusion

How to think it through

Diversification away from rice–wheat and sugarcane is needed for water, soil and nutrition. Challenges: MSP and procurement bias, free power, risk aversion, lack of markets, storage and processing for alternatives, small holdings, seed and knowledge gaps. Technology: precision farming, remote sensing for crop planning, drones, biotech and climate-resilient seeds, digital markets, cold chains, Agri Stack.

Model answer

Haryana's Mera Pani Meri Virasat offered farmers ₹7,000 an acre to give up paddy. Many still went back to rice. That one fact sums up the challenge: farmers stay with the crop that the market and the state make safe.

Price and market challenges

  • MSP with assured procurement mainly for rice and wheat; for pulses, oilseeds and millets procurement is thin.
  • No assured buyer for alternatives; price crashes in vegetables.
  • Weak value chains: few processing units for maize, millets or pulses.

Farm and input challenges

  • Free or cheap power and water favour thirsty crops.
  • Small holdings and risk aversion; one failed crop means debt.
  • Seed and knowledge gaps for new crops; extension still cereal-centric.
  • Climate risk in rainfed areas.

Opportunities from emerging technologies

  • Remote sensing and GIS to map soils and water and plan crops zone by zone.
  • Precision agriculture: sensors, drones and variable-rate input application.
  • Biotechnology: climate-resilient and short-duration varieties; genome-edited rice released in 2025.
  • Protected cultivation and hydroponics for high-value vegetables.
  • Digital markets: e-NAM, FPO platforms, ONDC for agri-produce.
  • Cold chains and solar cold rooms that keep perishables.
  • Agri Stack and AI advisories to tell a farmer what to grow and where to sell.

Policy support

  • Crop-neutral incentives, such as support per hectare rather than per quintal.
  • Missions for pulses and oilseeds, with procurement through NAFED and NCCF.
  • Price deficiency payments, as in Madhya Pradesh's Bhavantar, to cover the gap when market prices fall.
  • Crop insurance and credit designed for new crops, so the first season of change is not a gamble.

Technology can show the farmer a better crop; only a market can make him take the risk to grow it.

Draw: A two-column table: challenge vs matching technology.

Keywords, cases and data to drop in

Mera Pani Meri Virasat, MSP bias, risk aversion, remote sensing, precision agriculture, genome-edited rice (2025), hydroponics, e-NAM, ONDC, Agri Stack, crop-neutral support.

Where most answers lose marks

  • Writing only about technology. The first half on challenges carries equal marks.

11 crore Farmer IDs created five months early under the Digital Agriculture Mission and Agri Stack

The Centre is building a digital register of farmers, so that each farmer has one verified identity for all schemes. Under the Digital Agriculture Mission, 11 crore Farmer IDs were created by the night of 23 October, five months before the March 2027 deadline. With this ID, farmers need not submit the same papers again and again for loans, crop insurance or relief. For you, this links Agri Stack, the Kisan Credit Card, PMFBY and land-record reform.

Agrivoltaics World Conference in Delhi: PM-KUSUM’s next phase and the small-farmer test

Opening the 7th Agrivoltaics World Conference at Bharat Mandapam on 21 October 2026, the first in the Global South, Renewable Energy Minister Pralhad Joshi said the next phase of PM-KUSUM will carry one of the world’s most ambitious agrivoltaics programmes. Agriculture Minister Shivraj Singh Chouhan said the policy must work for the 85% of farmers who are small and marginal, with an average holding of just 0.96 hectare.

Agrivoltaics: Centre plans a scheme to push solar panels above farms; 5 GW seen in 3–4 years

MNRE Secretary Santosh Kumar Sarangi said on 19 October 2026 that the Centre is planning a central sector scheme to help States adopt agrivoltaics, either standalone or within PM-KUSUM 2.0. He expects capacity to cross 5 GW in three to four years if States notify feed-in tariffs. India hosts the 7th Agrivoltaics World Conference in New Delhi from 21 to 23 October.

Kufri Jamunia: ICAR-CPRI’s purple potato to fight hidden hunger

A PIB backgrounder of 18 October 2026 puts the spotlight on Kufri Jamunia, a purple-fleshed potato bred by ICAR’s Central Potato Research Institute and released in 2024. It has nearly twice the Vitamin C of a common potato and several times more zinc and iron, along with antioxidants called anthocyanins. The idea is clever: instead of asking people to change what they eat, make the food they already eat more nutritious. That is biofortification.
