Abstract
India's agriculture, vital for 50% of its workforce and food security for 1.4 billion people, Agrapples with intensifying climate stress. Erratic monsoons, frequent droughts in rainfed areas covering 60% of arable land, and extreme events like cyclones in coastal states have slashed yields by 20-40% in states such as Maharashtra, Rajasthan, and Bihar. Soil degradation—erosion, nutrient depletion, and salinization—affects 120 million hectares, inflating input costs and eroding farm incomes, with smallholders losing up to 30% of net returns annually.
Soil conservation practices offer resilience. Contour bunding and terracing in the Deccan Plateau reduce runoff by 50%, enhancing water retention and boosting sorghum and pearl millet yields by 15-25%. No-till farming with residue retention, promoted under the National Mission for Sustainable Agriculture, preserves soil organic carbon, cutting fertilizer needs by 20% and increasing wheat productivity in Indo-Gangetic plains. Cover cropping with legumes like cowpea fixes nitrogen, suppresses weeds, and curbs erosion in black soils of Vidarbha. Agroforestry integrates trees like neem and gliricidia, providing fodder, fuelwood, and microclimate moderation, as seen in watershed projects doubling incomes in Madhya Pradesh.
Integrated strategies—rainwater harvesting via farm ponds and check dams, alongside balanced nutrient management—yield synergies. In Gujarat's Kachchh district, such interventions raised cotton yields by 30% and farm incomes by 40%. Economic analyses from ICRISAT trials show 20-35% ROI through reduced inputs and premium prices for sustainable produce.
