\n\n<\/span>Challenges of Soil Degradation in India<\/strong><\/span><\/span><\/h2>\nIndia’s agricultural sustainability is under threat due to deteriorating soil health. Studies indicate that only less than 5% of Indian soils possess high nitrogen levels, and just 20% have adequate organic carbon. The existing fertilizer subsidy system, which disproportionately favours urea, has caused imbalanced nutrient application, with excessive nitrogen and insufficient phosphorus and potassium use. This imbalance not only hampers agricultural productivity but also exacerbates environmental degradation.<\/span><\/p>\nTo secure long-term soil health and agricultural sustainability, comprehensive systemic reforms in fertilizer policies and nutrient management are urgently required.<\/span><\/p>\nCurrent Status of Soil Degradation in India<\/strong><\/span><\/h3>\n\n- Extent of Degradation:
\n<\/strong>According to the Desertification and Land Degradation Atlas of India (SAC 2021), 97.85 million hectares, or 29.77% of India’s geographical area, experienced land degradation during 2018-19.<\/span><\/li>\n- Geographic Spread and Severity:<\/span>
\nThe most affected regions are semi-arid and dry sub-humid areas, with states like Rajasthan, Maharashtra, Gujarat, and Telengana witnessing significant degradation.<\/span><\/li>\n- Rajasthan accounts for over 21 million hectares of degraded land, mainly due to wind erosion in its arid zones.<\/span><\/li>\n
- Desertification has intensified, with 83.69 million hectares now classified as drylands undergoing desertification\u2014a net increase of over 1 million hectares since 2003-05.<\/span><\/li>\n<\/ul>\n
Issues Leading to Soil Degradation in India<\/strong><\/span><\/h3>\n\n- Unsustainable Agricultural Practices:
\n<\/strong>India’s heavy reliance on intensive farming methods, such as excessive use of chemical fertilizers, pesticides, and mono cropping, has caused severe nutrient depletion and soil acidification.<\/span><\/li>\n<\/ol>\nFor instance, states like Punjab and Haryana are experiencing declining organic carbon levels due to the legacy of high-yield cropping from the Green Revolution.<\/span><\/p>\nAdditionally, organochlorine insecticides like DDT and HCH make up over 70% of pesticides used in India, further exacerbating soil degradation.<\/span><\/p>\n\n- Deforestation and Urbanization:
\n<\/strong>Rapid deforestation for agriculture, infrastructure development, and urban expansion has significantly accelerated soil erosion and reduced water retention.<\/span><\/li>\n<\/ol>\nFrom 2013 to 2023, 95% of India’s tree cover loss occurred in natural forests.<\/span><\/p>\nFor example, the Western Ghats, a global biodiversity hotspot, lost 5% of its evergreen forest cover, impacting local soil fertility.<\/span><\/p>\n\n- Overgrazing and Unsustainable Livestock Management:
\n<\/strong>Unregulated grazing in arid and semi-arid regions, such as Rajasthan and Gujarat, has led to vegetation loss and topsoil erosion.<\/span><\/li>\n<\/ol>\nWith over 535 million livestock, India’s grazing lands are under immense pressure, exceeding their sustainable carrying capacity and resulting in denuded plant cover.<\/span><\/p>\n\n- Water Mismanagement and Irrigation Practices:
\n<\/strong>Excessive groundwater extraction and inefficient irrigation methods like flood irrigation have led to soil salinization and water logging.<\/span><\/li>\n<\/ol>\nAround 6.74 million hectares in India are affected by salinity, with Punjab experiencing degradation in nearly 50% of its land due to over-irrigation.<\/span><\/p>\nEstimates suggest that by 2050, up to 50% of India\u2019s arable land could become salt-affected.<\/span><\/p>\n\n- Industrial Pollution and Mining Activities:<\/strong><\/span>
\nHeavy metals, chemicals, and pollutants from industries and mining activities are contaminating soil ecosystems, especially in states like Odisha and Jharkhand.<\/span><\/li>\n<\/ol>\nFor instance, toxic waste from coal mining and fly ash dumps has rendered vast areas unproductive.<\/span><\/p>\nThe Sterlite Copper plant in Tamil Nadu caused severe soil and water contamination through the discharge of harmful chemicals.<\/span><\/p>\n\n- Climate Change and Extreme Weather Events:
\n<\/strong>Erratic weather patterns caused by climate change, including floods and droughts, have worsened soil erosion and nutrient loss.<\/span><\/li>\n<\/ol>\nThe 2023 Himachal Pradesh floods led to extensive topsoil loss in agricultural zones.<\/span><\/p>\nProjections indicate that areas with high or very high soil erosion rates will increase from 35.3% to 40.3% by the end of the century.<\/span><\/p>\n\n- Shifting Cultivation and Slash-and-Burn Practices:
\n<\/strong>In north eastern states like Nagaland and Manipur, slash-and-burn practices degrade soil fertility by destroying organic matter.<\/span><\/li>\n<\/ol>\nA total of 4,925 km\u00b2 in Northeast India has been identified as jhuming hotspots, with over 62% in Arunachal Pradesh, Assam, and Mizoram, leading to extensive erosion and biodiversity loss.<\/span><\/p>\n\n- Unregulated Construction and Infrastructure Projects:<\/strong><\/span>
\nLarge-scale construction for roads, dams, and urbanization strips topsoil and disrupts natural drainage systems.<\/span><\/li>\n<\/ol>\nFor example, the construction of the Char Dham Highway in Uttarakhand has resulted in over 300 landslides, causing significant soil instability.<\/span><\/p>\n\n- Invasive Species:<\/strong><\/span>
\nInvasive plants like Lantana camara are depleting soil nutrients and disrupting native biodiversity.<\/span><\/li>\n<\/ol>\nRecent studies show that invasive species are present in 22% of natural areas and could threaten up to 66% of these areas in the future<\/span><\/p>\n![\"https:\/\/triumphias.com\/sociology-offline.php\"](\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2024\/11\/WhatsApp-Image-2024-11-28-at-16.08.34-1-104x150.jpeg\") <\/p>\n
Indian Government Initiatives Related to Soil Conservation Remain Partially Effective<\/strong><\/span><\/h3>\n\n- Fragmented Policy Framework:<\/strong><\/span>
\nIndia’s soil conservation efforts are divided across multiple ministries and schemes, resulting in a lack of coordination and unified focus.<\/span><\/li>\n<\/ol>\nFor example, the Soil Health Card Scheme operates independently of complementary programs like the Pradhan Mantri Krishi Sinchayee Yojana (irrigation) and MNREGA (land restoration).<\/span><\/p>\nThis siloed approach hinders a holistic strategy for soil management.<\/span><\/p>\n\n- Inadequate Implementation and Monitoring:
\n<\/strong>Although initiatives like the Soil Health Card Scheme and Paramparagat Krishi Vikas Yojana (PKVY) aim to improve soil health, their on-ground implementation faces challenges.<\/span><\/li>\n<\/ol>\nAs of 2022, only 33% of farmers reportedly follow soil health recommendations.<\/span><\/p>\nAdditionally, insufficient accountability and the absence of real-time feedback mechanisms reduce the effectiveness of these schemes.<\/span><\/p>\n\n- Neglect of Regional Specificity:
\n<\/strong>Many soil conservation programs adopt a generic approach and fail to address region-specific challenges, such as:<\/span><\/li>\n<\/ol>\n\n- Desertification in Rajasthan,<\/span><\/li>\n
- Salinity in Gujarat, and<\/span><\/li>\n
- Waterlogging in Punjab.<\/span>
\nThis “one-size-fits-all” approach diminishes the impact of these programs on diverse soil conditions.
\n<\/span>4. Weak Linkages Between Research and Implementation:
\n<\/strong>India’s research outputs from institutions like ICAR and IITs are not adequately translated into practical solutions for farmers.<\/span><\/li>\n- Technologies like biochar and microbial fertilizers remain underutilized due to a lack of government support for commercialization and field-level adoption.<\/span><\/li>\n
