Climate change, environmental degradation and socio-economic uncertainties pose significant challenges to agricultural sustainability, particularly for rural populations dependent on farming. Monoculture systems, adopted to meet the rising food demand, have aggravated soil and water degradation, biodiversity loss and increased greenhouse gas emissions. Crop diversification has emerged as a sustainable strategy to enhance resilience, productivity and livelihood security. Practices such as crop rotation, intercropping, mixed cropping, and the use of regionally adapted varieties, legumes and perennials reduce production risks, improve soil health, lower pest and disease incidence, enhance resilience to climatic extremes and stabilise farm income. In India, where agriculture is largely rainfed and constrained by fragmented landholdings, declining resources and market imperfections, diversification provides a pathway to balance food security with environmental sustainability. Shifting from low-value, resource-intensive crops to high-value, climate-resilient and market-oriented crops through horizontal and vertical diversification can improve productivity, profitability and nutritional security. However, adoption is limited by inadequate infrastructure, poor access to inputs and technology, weak market linkages and policy barriers, which must be addressed through supportive policies, targeted investments, strengthened value chains and farmer-participatory approaches.
