A recent study employing the Revised Universal Soil Loss Equation (RUSLE) has uncovered alarming trends in soil erosion across India, shedding light on significant challenges to agricultural productivity and environmental sustainability.
The study’s findings reveal widespread soil degradation, with approximately 30% of the country’s landmass experiencing “minor” erosion and an additional 3% facing “catastrophic” topsoil loss. Identified hotspots for soil erosion, such as the Brahmaputra Valley in Assam and Odisha, underscore the severity of the issue, emphasising the urgent need for intervention.
Soil erosion, influenced by natural processes and human activities, poses a multifaceted threat to soil health and agricultural viability. Factors such as deforestation, poor agricultural practices, overgrazing, and construction disrupt the delicate balance of soil structure, leading to the detachment and transportation of soil particles. In India, low organic carbon content, nutrient deficiencies, water management issues, and socioeconomic factors exacerbate soil erosion, perpetuating the cycle of degradation. The decline in organic carbon content and nutrient deficiencies, compounded by water management challenges, presents significant hurdles to soil health. The reliance on chemical fertilisers further accelerates soil degradation, compromising fertility and agricultural productivity. Socioeconomic factors like land fragmentation and economic constraints hinder the adoption of sustainable soil management practices, exacerbating the problem.
To combat soil erosion and degradation, the Indian government has launched various initiatives under the National Mission for Sustainable Agriculture (NMSA). These initiatives, including the Soil Health Card Scheme, Paramparagat Krishi Vikas Yojana (PKVY), Neem Coating of Urea, and Nutrient-Based Subsidy (NBS) Scheme, aim to promote sustainable farming practices, reduce fertiliser wastage, and enhance soil health and productivity. Addressing soil erosion requires collaborative efforts from government bodies, farmers, and environmental organisations. By implementing proactive measures and adopting sustainable land management practices, stakeholders can mitigate the adverse effects of soil erosion, ensuring the long-term health and productivity of India’s soils and safeguarding agricultural sustainability and environmental stability.
