Revision summary
Rice–wheat worked because HYV seed, irrigation, fertiliser, MSP, and procurement aligned. Punjab–Haryana–western UP became India’s grain insurance. The same incentives mined aquifers with paddy on a semi-arid plain. Stubble burning, soil nutrient imbalance, and cereal-heavy public buying are the other costs. Diversification needs price and offtake, not only a technical residue machine.

Introduction
The rice–wheat rotation on the Indo-Gangetic plains, especially Punjab, Haryana, and western Uttar Pradesh, is India’s most famous food-security machine. It succeeded because seed, water, price, and procurement lined up. The same lineup became a bane when groundwater, soil, air, and fiscal cost could no longer hide in the yield chart.
Body
Factors that made it a success
- Semi-dwarf HYV wheat and rice that responded to fertiliser and irrigation, backed by ICAR, State universities, and a public seed chain.
- Assured irrigation: Bhakra and later canal commands, then a dense tube-well grid powered by cheap or free electricity.
- Chemical package: nitrogen-heavy fertiliser, pesticides, and later herbicides that fitted a mechanised calendar.
- Price and offtake: MSP plus FCI / State agency procurement turned paddy and wheat into quasi-cash crops with a government cheque.
- Extension and machinery: tractors, combines, and a rural engineering culture that could sow wheat after a late paddy harvest (including zero-till in some pockets).
- Public research on the rotation itself: short-duration rice so wheat still fitted the winter window.
- Political economy: surplus States became the granary of PDS and buffer stocks, which rewarded the rotation year after year.
How it became a bane in Green Revolution States
- Groundwater collapse: paddy is a water-guzzling crop on a semi-arid Punjab–Haryana landscape. Free power and a paddy MSP made mining the aquifer rational for the farmer and lethal for the next decade.
- Soil fatigue: rice–wheat–rice–wheat without enough organic matter, micronutrient deficit, zinc and manganese issues, and a chemical treadmill.
- Residue and air: combine-harvested paddy straw is hard to manage in the short window before wheat; stubble burning became a regional air-health crisis for Delhi-NCR as well as the fields.
- Monoculture risk: pest shifts, falling water tables, and climate extremes hit a system with little crop diversity.
- Fiscal and nutritional distortion: public money buys rice and wheat the country already stores, while oilseeds, pulses, and millets stay under-incentivised — a C2+50 / MSP debate that is also a cropping-pattern debate.
- Labour and social: migrant labour dependence, then COVID-year shocks; a generation locked to a procurement crop rather than horticulture or industry.
- Ecological dead-ends: uranium and other geogenic worries in some Punjab waters, canal-water quality, and loss of indigenous basmati niches to a procurement-grade grain.
Rebalancing without romantic yield-suicide
- Diversification toward maize, pulses, oilseeds, horticulture, with procurement and processing that actually show up, not only a pamphlet.
- Direct seeding of rice, shorter-duration varieties, Happy Seeder / SMS for residue, and electricity/water pricing that tells the truth about the aquifer.
- PM-KUSUM and solarisation must not become a new subsidy to pump the last of the water.
- MSP plus open-ended paddy procurement is the political core of the bane; technical fixes without a price signal will leak.

Conclusion
Rice–wheat succeeded through HYV seed, irrigation, chemicals, MSP, and FCI offtake. In the old Green Revolution States it became a bane by mining groundwater, exhausting soils, burning straw, and locking farmers and the exchequer into two cereals. Success was food in the godown. The bane is water, air, and a future crop map that cannot stay paddy-wheat forever.

-
Should Punjab stop growing rice?
It should grow far less water-intensive rice, and more other crops, if income is protected. A sudden ban without offtake is a farm revolt, not ecology.
-
Is the bane only environmental?
No. It is also fiscal (stocks and subsidy) and nutritional (too little pulse and oilseed incentive).

What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient features of their solid waste management initiatives.
Indian Economy
• Rapid urbanization has made solid waste management a critical environmental and public health crisis in India. • Key challenges include lack of source segregation, inadequate processing infrastructure, reliance on unprotected informal workers, and financially weak urban local bodies. • The policy framework relies on the SWM Rules 2016, Swachh Bharat Mission (Urban), and Plastic Waste Management Rules 2016. • Indore succeeded through 100% source segregation, zero dump-site remediation, and strict enforcement with digital monitoring. • Delhi failed due to overloaded legacy landfills (Ghazipur, Bhalswa), lack of decentralization, and fragmented municipal governance. • A successful transition requires moving to a circular economy focused on source segregation, decentralized processing, and polluter accountability.

What is Agentic Artificial Intelligence (AI)? Explain its working. Describe its applications with suitable examples. Discuss the advantages, risks and challenges associated with agentic AI systems.
Indian Economy
Agentic Artificial Intelligence represents an advanced paradigm where AI systems operate with autonomy, setting goals and executing complex workflows without constant human prompts. Unlike traditional generative AI that merely responds to queries, agentic AI uses perception, planning, memory, and tool-use to achieve multi-step objectives. Its applications span across autonomous software engineering, supply chain optimization, and automated financial trading. While offering massive productivity gains and dynamic problem-solving, these systems pose significant risks including lack of transparency, alignment failures, security vulnerabilities, and ethical dilemmas. Governance frameworks and robust guardrails are essential to harness their potential safely.
