Abstract

In rainfed regions of India, where agriculture is largely reliant on rainfall. Soil erosion, water scarcity and land degradation pose threats to the viability of agricultural enterprises in rainfed areas, which comprise over 39.11 lakh ha, or 58.21 % of the net planted area. Soil water conservation is a tailored-made land management strategy that encompasses increased water availability in the soil matrix. This process involves minimizing evaporative losses, improving water infiltration and promoting retention of available moisture to support plant growth and ecosystem stability. By maintaining optimal soil moisture levels, these practices contribute significantly to agricultural resilience, especially in arid and semi-arid regions, while simultaneously mitigating the adverse effects of drought and water stress on crop productivity. This paper emphasizes the necessity of tailored conservation strategies to address the unique challenges posed by erratic rainfall patterns and fragile ecosystems. It discusses the critical significance of soil water conservation in enhancing soil health, supporting agricultural productivity and fostering environmental sustainability in regions prone to drought. Techniques such as subsoiling, conservation tillage, contour cultivation and various mulching methods are elaborated, highlighting their effectiveness in improving soil moisture retention, reducing erosion and promoting crop resilience. The integration of innovative practices such as crop rotation, intercropping and the use of soil amendments also shows promise in enhancing moisture conservation and agricultural yields. Furthermore, the document emphasizes the necessity of these practices in the wake of climate change, advocating for future advancements that combine traditional knowledge with cutting-edge technology. By integrating these soil and water conservation measures, the research advocates for sustainable agricultural practices that not only enhance productivity but also protect environmental integrity in rainfed regions of India. Overall, it underscores the imperative of sustainable agricultural practices in ensuring food security and ecological balance.
