Context
- India, with a staggering population of 145 crore, has made significant strides in achieving self-reliance in food and nutrition over the past seven decades.
- These accomplishments have primarily been driven by the expansion of agricultural lands and the intensification of practices during the Green Revolution.
- Current agricultural systems may fall short of meeting this goal due to their unsustainable practices and mounting ecological costs.
Challenges of Current Agricultural Practices
- Soil Degradation
- The overuse of chemical fertilisers has caused significant depletion of soil health.
- Over six decades of reliance on synthetic inputs have reduced the soil organic carbon content from a healthy 2.4% in 1947 to a critically low 0.4% today.
- This degradation not only undermines the soil's ability to support crops but also jeopardizes its role in carbon sequestration, further exacerbating climate change.
- Soil with organic carbon below the threshold of 1.5% loses its arability, making it unsuitable for sustainable farming.
- Economic Costs
- The financial burden of soil degradation is staggering. Over 70 years, the loss of soil organic carbon alone has cost India ₹47.7 lakh crore ($564 billion), translating to an annual loss of ₹68,243 crore ($8.06 billion).
- Additionally, the Indian government spends ₹2 lakh crore ($25 billion) annually on subsidies for synthetic fertilisers.
- These subsidies, while intended to support farmers, inadvertently encourage excessive and inefficient use of chemical inputs, further degrading the soil.
- Declining Fertiliser Efficiency
- The response ratio of fertilisers has seen a sharp decline over the decades. In the 1960s, every kilogram of NPK fertiliser produced 12.1 kilograms of grain.
- By 2010-2017, this had dropped to just 5.1 kilograms, signalling diminishing returns on fertiliser use.
- This decline is a direct consequence of deteriorating soil health, making it increasingly difficult to achieve high yields.
- Environmental Impact
- The environmental costs of India’s current agricultural practices are profound.
- The use of synthetic fertilisers contributes to approximately 25 million tonnes of greenhouse gas emissions annually, costing the country an additional ₹14,813 crore ($1.75 billion).
- These emissions exacerbate global warming and threaten the long-term sustainability of agriculture.
- Furthermore, intensive farming practices deplete natural resources such as groundwater and reduce biodiversity, compounding the ecological crisis.
- Food Security Risk
- If the current trends persist, India could face food shortages as early as 2035.
- This risk is driven by a combination of factors: the growing population, increased food demand, declining soil productivity, and the adverse impacts of climate change.
- Without immediate intervention to address these issues, India’s ability to feed its citizens will be severely compromised.
- Social and Health Costs
- Beyond the economic and environmental impacts, intensive agriculture poses significant social and health challenges.
- The widespread use of chemical inputs has led to contamination of water and food supplies, adversely affecting public health.
- Additionally, the heavy financial reliance on synthetic inputs traps farmers in a cycle of debt, contributing to rural distress and social inequities.
Necessary Steps to Address these Challenges
- A Shift Towards Sustainable Agriculture
- To address these challenges, India must transition to a climate-resilient, nature-based agricultural model.
- Such a system prioritises ecological intensification over traditional intensification, reducing dependence on synthetic inputs while enhancing soil health, biodiversity, and overall productivity.
- Regenerative farming, rooted in the principles of agroecology, emerges as a promising alternative.
- This approach reduces input costs, conserves natural resources, and boosts farm productivity, while also promoting the well-being of farmers and consumers alike.
- Mainstreaming Regenerative Practices
- The Prime Minister’s National Mission on Natural Farming serves as a critical step toward safeguarding Indian agriculture.
- By mainstreaming regenerative practices, India can ensure food, nutritional, and ecological security.
- Studies have demonstrated that community-managed natural farming not only improves agricultural output but also builds social capital, enhances the health of farming communities, and fosters environmental sustainability.
- The Need for Evidence and Policy Reform
- For India to fully embrace regenerative farming, intensive and longitudinal research is necessary across all 15 agro-climatic zones.
- Such studies will provide scientific evidence of the benefits of regenerative practices, helping to create awareness and inform policy frameworks.
- Disseminating this evidence will also strengthen political will, creating the development of large-scale models for adopting sustainable agriculture.
- Agroecological principles must guide this transformation and these include biological pest control, nutrient cycling, soil health enhancement, and biodiversity conservation.
- A knowledge-intensive approach, supported by participatory and decentralised pedagogies, will empower farmers to implement these practices effectively.
Way Forward
- A Radical Transformation in Agriculture
- India’s vision of achieving net zero status by 2070 aligns with the goals of redesigning its agricultural systems.
- By focusing on regenerative farming and ecological intensification, India can mitigate the risks of climate change, reduce hidden costs of agriculture, and ensure long-term food security.
- A radical transformation of the agricultural paradigm, underpinned by robust evidence and policy support, is essential to secure the nation's nutritional and ecological future.
- Building a Scientific and Policy Framework
- Redesigning Indian agriculture requires a comprehensive strategy grounded in scientific evidence and participatory approaches.
- Intensive field research across India’s 15 agro-climatic zones is essential to validate the benefits of regenerative farming and generate localised solutions.
- Public dissemination of this evidence can foster awareness, political will, and policy support for scaling up sustainable practices.
- Moreover, knowledge-intensive systems supported by decentralised pedagogies can empower farmers with the skills and resources to adopt agroecological principles.
Conclusion
- India stands at a crossroads in its agricultural journey and the current model of intensive agriculture is unsustainable and poses significant risks to food security, ecological balance, and economic stability.
- A radical shift towards regenerative and ecological farming is the need of the hour because regenerative farming holds the key to balancing productivity with environmental stewardship.
- By embracing this transformation, India can ensure its agricultural system remains resilient, productive, and sustainable, securing a healthier and more prosperous future for its people and the planet.
