The launch of the National Mission on Natural Farming (NMNF) marks a strategic shift in India’s agricultural policy towards sustainable and chemical-free practices. With a budget of ₹2,481 crore, this mission aims to improve soil health, reduce farmers’ input costs, and promote climate resilience.
Background
Natural farming, a traditional Indian practice, gained prominence as an alternative to the Green Revolution’s chemical-intensive methods, which have led to soil degradation and increased farmer debt. The NMNF, a centrally sponsored scheme, builds upon earlier initiatives like the Bharatiya Prakritik Krishi Paddhati (BPKP), aiming to scale up these practices scientifically.
Government Schemes and Policies
The NMNF is a standalone Centrally Sponsored Scheme under the Ministry of Agriculture & Farmers’ Welfare. It complements the existing Paramparagat Krishi Vikas Yojana (PKVY) which promotes organic farming. The mission provides financial assistance and aims to establish 10,000 Bio-Input Resource Centres (BRCs) to ensure the availability of natural farming inputs. The scheme is a key component of the government’s push for sustainable agriculture and aligns with the broader goal of doubling farmers’ income by reducing input costs.
Constitutional Provisions, Rules, Laws, SC Verdicts, UN Resolutions
Article 48A of the Directive Principles of State Policy mandates that the State shall “endeavor to protect and improve the environment.” Article 51A(g) imposes a fundamental duty on every citizen to “protect and improve the natural environment.” The Supreme Court, in various verdicts like the M.C. Mehta case, has established the right to a clean and healthy environment as a part of the fundamental right to life under Article 21. Globally, the NMNF aligns with the UN’s Sustainable Development Goal 2 (SDG 2), which aims to “end hunger, achieve food security and improved nutrition and promote sustainable agriculture.”
Agriculturist
Agriculturists have a mixed but largely positive view of natural farming. Proponents like Subhash Palekar champion it as a low-cost, high-yield model that restores soil health and biodiversity. They argue it makes farming more resilient to climate shocks. However, critics and some agricultural scientists express concerns about its scalability and potential for initial yield drops. They call for more long-term scientific studies and robust support systems to ensure a smooth transition, particularly for farmers who have relied on chemical inputs for decades.
Significance
The NMNF’s significance lies in its potential to create a paradigm shift in Indian agriculture. By focusing on indigenous knowledge and local resources, it can drastically reduce farmers’ dependency on external inputs, leading to substantial cost savings. It is also a crucial step towards climate-resilient agriculture by improving soil health and water retention. The mission’s emphasis on branding and certification for natural products can help farmers fetch better market prices, thereby boosting their income and making farming a more viable profession.
Definition of Technical Terms

- Beejamrit: A seed treatment liquid made from cow dung, cow urine, and lime, used to protect seeds from fungal and bacterial diseases.
- Mulching: Covering the soil with a layer of organic material like straw or leaves to conserve moisture, regulate soil temperature, and prevent weed growth.
Farming
Natural farming is fundamentally different from organic farming. While both are chemical-free, natural farming prohibits all external inputs, even organic ones, and focuses on in-situ biomass recycling and local resources. It prioritizes the creation of a self-sustaining ecosystem where the soil’s natural microbiome and a diverse crop system provide the necessary nutrients. The role of the local breed of cow is central to this model, as its dung and urine are the primary ingredients for key natural inputs.
Impacts on Environment
Natural farming has a profoundly positive impact on the environment. By eliminating synthetic fertilizers and pesticides, it prevents soil and water contamination. The practice of mulching and minimal tilling helps in carbon sequestration, making the soil a net carbon sink. It also enhances biodiversity by fostering a healthy soil ecosystem and encouraging diverse crop systems. Additionally, it improves water efficiency by enhancing the soil’s water-holding capacity.
Challenges
The primary challenges for the NMNF are scaling up and ensuring consistent yields. Natural farming requires a significant behavioral and knowledge-based change from farmers, which can be difficult after decades of chemical-intensive farming. The initial years of transition may see a drop in productivity, posing a financial risk to small farmers. There is also a lack of sufficient scientific validation and long-term data to prove its efficacy across all agro-climatic zones of India.

India's Ethanol Blending Policy
Context
India’s aggressive push for E20 (20% ethanol-blended petrol) aims to reduce dependence on foreign oil and cut carbon emissions. However, this rapid transition is raising concerns among motorists about reduced mileage, engine damage, and increased maintenance costs, especially for older vehicles.
Background
India’s ethanol blending program is a strategic move for energy security, aligning with global efforts to transition to biofuels. While countries like Brazil have decades of experience with a phased rollout, India’s accelerated timeline presents unique challenges, highlighting the trade-offs between policy goals and practical implementation.
Government Schemes and Policies
The Ethanol Blended Petrol (EBP) Programme is a key government initiative. In 2021, the government advanced its E20 blending target from 2030 to 2025. This policy is supported by schemes that provide incentives for sugar mills and grain-based distilleries to produce ethanol. The National Policy on Biofuels 2018 further provides a framework for increasing ethanol production from various sources, including molasses, sugarcane, and damaged food grains, aligning with the “Atmanirbhar Bharat” (Self-Reliant India) and “PM-JIVAN Yojana” (Pradhan Mantri Jaiv Indhan- Vatavaran Anukool Fasal Awasesh Nivaran Yojana) initiatives.
Constitutional Provisions, Rules, Laws, SC Verdicts, UN Resolutions
The government’s policy is guided by the broader principles of environmental protection (Article 48A of the DPSP) and sustainable development. The Motor Vehicles Act, 1988, and its subsequent amendments provide the legal framework for vehicle standards, and the government has issued notifications for new vehicle compatibility. The policy also aligns with global environmental commitments, such as the Paris Agreement, by aiming to reduce greenhouse gas emissions and promote a cleaner energy mix.
Mechanical Engineer
While they acknowledge ethanol’s potential to reduce emissions and improve octane rating, they raise concerns about its hygroscopic nature and corrosive properties. They point out that older, mechanically carbureted engines are not designed to handle E20 fuel. This can lead to corrosion of rubber components and fuel system blockages due to rust. They stress that modern engines with Electronic Control Units (ECUs) are better equipped to handle ethanol blends, but older vehicles would require costly and complex modifications, which are often not feasible.
Significance
India’s ethanol blending program is a multi-faceted policy with significant implications. It aims to reduce India’s massive crude oil import bill, which is a major drain on foreign exchange reserves. It also offers a sustainable solution to surplus sugar production and damaged food grains, providing an alternative revenue stream for farmers. From an environmental perspective, it is a key step towards reducing carbon emissions and urban air pollution, contributing to India’s climate goals.
Definition of Technical Terms
- Ethanol: A type of alcohol, also known as ethyl alcohol, produced from plant materials like sugarcane or grains. It is a renewable biofuel.
- E20 Fuel: A blend of petrol containing 20% ethanol and 80% petrol by volume.
- Hygroscopic Nature: The property of a substance to absorb and hold water molecules from the surrounding environment. Ethanol is highly hygroscopic.
- Octane Number: A measure of a fuel’s resistance to “knocking” or premature combustion in an internal combustion engine. A higher octane number indicates better knock resistance.
- Calorific Value: The amount of heat energy released when a fuel is completely burned.
- Electronic Control Unit (ECU): A sophisticated computer system in modern vehicles that controls various engine functions, including fuel injection and ignition timing.
Automobile
In this transition lies in the difference between older and newer vehicle technologies. Older vehicles, especially those manufactured before the BS-VI emission norms, use a carburetor system that lacks the sensors to adjust the air-fuel ratio for different fuel compositions. As a result, when these vehicles run on E20, their engines may suffer from improper combustion, leading to reduced mileage and potential long-term damage. Modern vehicles with ECUs, on the other hand, can automatically recalibrate the engine settings to account for the higher oxygen content in ethanol, ensuring optimal performance.
Impacts on Transportation
The policy’s impact on the transportation sector is significant and complex. It introduces a two-tiered system where newer vehicles are compatible with E20, while older vehicles face potential performance and maintenance issues. This could lead to a surge in demand for vehicle retrofitting services and an increase in maintenance costs for a large segment of the vehicle population. While the long-term goal is to transition to a more sustainable fleet, the immediate challenges could inconvenience millions of vehicle owners and affect the used car market.
Challenges
The primary challenges include the lack of public awareness about E20 compatibility, the absence of a clear and affordable retrofitting plan for older vehicles, and potential supply chain bottlenecks for ethanol production. The rapid timeline for E20 implementation may also strain the production capacity of both the ethanol industry and the automotive sector. Ensuring consistent quality and preventing fuel adulteration across the country’s vast network of petrol pumps will also be a major logistical challenge.
Way Forward
The government should implement a more phased and consultative approach to the transition, perhaps by initially promoting E10 and gradually moving to E20. A comprehensive public awareness campaign is needed to educate motorists about the policy, its benefits, and the necessary precautions. A clear, subsidized, and accessible retrofitting program for older vehicles must be developed and communicated. Finally, a robust regulatory framework is required to ensure fuel quality and address consumer grievances effectively.
