What are the major factors responsible for making rice-wheat system a success? In spite of this success how has this system become bane in India?

The Rice-Wheat System (RWS) is India’s most widely adopted cropping pattern, predominantly practiced in the Indo-Gangetic plains (Punjab, Haryana, Western Uttar Pradesh). Introduced during the Green Revolution in the 1960s, it successfully transformed India from a food-deficient nation into a self-sufficient and net food-exporting country.

Major Factors Responsible for the Success of the Rice-Wheat System

1. Institutional Support and Favorable Policies:
   • Assured Procurement: The open-ended procurement policy of the Food Corporation of India (FCI) for rice and wheat at Minimum Support Price (MSP) provided guaranteed income and shielded farmers from market volatility.
   • Robust APMC Network: The establishment of well-connected mandis ensured a ready market for the produce.
2. Technological Interventions:
   • High Yielding Variety (HYV) Seeds: Introduction of dwarf varieties of wheat (e.g., Kalyan Sona) and semi-dwarf varieties of rice (e.g., IR8) significantly multiplied yields per hectare.
   • Mechanization: High adoption of tractors, seed drills, and combine harvesters enabled timely sowing and harvesting, crucial for the tight turnaround time between the Kharif (rice) and Rabi (wheat) seasons.
3. Subsidized Inputs:
   • Irrigation and Power: The expansion of canal networks and heavily subsidized (often free) electricity for tube wells ensured the massive water requirement for paddy was met seamlessly.
   • Fertilizers: High subsidies on urea and other synthetic fertilizers made input costs affordable, encouraging heavy application to maximize output.
4. Extension Services and Research: Strong backing by the Indian Council of Agricultural Research (ICAR), Krishi Vigyan Kendras (KVKs), and state agricultural universities helped transfer laboratory technology to farmers' fields.

How the System has Become a Bane in India

Despite ensuring food security, the relentless continuation of the intensive RWS has led to severe ecological, economic, and nutritional consequences, rendering it unsustainable.

1. Ecological and Environmental Consequences:

• Groundwater Depletion: Rice is a highly water-intensive crop. Its cultivation in semi-arid regions like Punjab and Haryana has led to severe groundwater mining. Over 75% of blocks in Punjab are now classified as 'dark' or over-exploited.
• Soil Degradation: Continuous cultivation without fallow periods has led to a decline in soil organic carbon and micronutrients (like zinc and sulfur). The highly subsidized urea has skewed the NPK (Nitrogen, Phosphorus, Potassium) application ratio (e.g., 31:8:1 in Punjab against the ideal 4:2:1), causing soil salinization and loss of fertility.
• Air Pollution (Stubble Burning): The mechanized harvesting of rice leaves behind stubble. Due to the short window before wheat sowing, farmers resort to crop residue burning, causing severe winter smog in the National Capital Region (NCR) and North India.

2. Economic and Agricultural Challenges:

• Yield Plateauing and Rising Input Costs: The marginal productivity of fertilizers and water has declined. Farmers are forced to apply more inputs to get the same yield, leading to a rise in the cost of cultivation and increasing farmer indebtedness.
• Fiscal Burden: The unending cycle of MSP procurement and massive subsidies on power, water, and fertilizers exerts a massive fiscal strain on both State and Central governments.
• Pest and Disease Vulnerability: Monoculture over decades has altered the pest dynamics, leading to increased attacks (e.g., Yellow Rust in wheat, Brown Plant Hopper in rice) and higher pesticide usage, further increasing input costs.

3. Nutritional and Socio-Economic Impact:

• Decline of Crop Diversity: The RWS displaced crucial crops like pulses, oilseeds, and coarse cereals (millets). India now imports nearly 60% of its edible oil and struggles with pulse inflation.
• Hidden Hunger: The over-reliance on a cereal-heavy diet has exacerbated "hidden hunger" (micronutrient deficiency), as the production of protein-rich pulses and nutrient-dense millets was sidelined.
• Regional Disparities: The success of RWS was concentrated in the North-West, leaving Eastern India (despite having abundant water) historically lagging in agricultural growth, exacerbating regional economic inequalities.

Way Forward

To rectify the anomalies of the Rice-Wheat system, agriculture must be realigned with agro-climatic zones:

• Crop Diversification: Shifting from paddy to maize, cotton, pulses, and oilseeds in the North-West. The Haryana government's Mera Pani Meri Virasat scheme (incentivizing farmers to shift away from paddy) is a positive step.
• Promoting Millets (Shree Anna): Leveraging the International Year of Millets (2023) to create domestic demand and establish robust supply chains for climate-resilient crops.
• Rationalizing Subsidies: Transitioning to Direct Benefit Transfers (DBT) for fertilizers and electricity to plug leakages and prevent the overuse of natural resources. Promoting initiatives like PM-PRANAM to reduce chemical fertilizer use.
• Decentralized Procurement: Strengthening MSP procurement for pulses and oilseeds to provide a level playing field, while focusing the next Green Revolution (Bringing Green Revolution to Eastern India - BGREI) in the water-rich eastern states for rice cultivation.

The Rice-Wheat system was a product of its time, designed to solve the calorie-deficit crisis of the 1960s. Today, Indian agriculture requires a paradigm shift from "calorie-centric" policies to "nutrition-centric and ecology-centric" sustainable farming.
