5 pages, India's agrarian economy contributes 21% to the country's GDP and provides employment to 60% of the population. Rainfed agriculture constitutes 67% of the net sown area, contributing 44% of food grains and supporting 40% of the population. To meet the increasing demand for food grains, it is crucial to enhance the productivity of rainfed areas from the current 1 t/ha to 2 t/ha over the next two decades. However, the quality of natural resources in these regions is deteriorating due to overexploitation, and rainfed areas face biophysical and socio-economic constraints affecting crop and livestock productivity.
This paper critically examines economically viable technologies for rainfed agriculture, including soil and rainwater conservation, efficient crops and cropping systems tailored to the growing season, and suitable implements for timely sowing and labor-saving. Sustainable practices such as integrated nutrient and pest management (INM and IPM) are emphasized. Additionally, the paper highlights interventions in dryland technologies to utilize marginal lands through alternative land-use systems like silvopasture, rainfed horticulture, and tree farming, demonstrated on a watershed basis. The integration of livestock with arable farming systems and the incorporation of indigenous knowledge are also discussed. Finally, the paper advocates for the formation of self-help groups, innovative extension tools such as portable rainfall simulators, and focus group discussions to facilitate the adoption of rainfed technologies by farmers. A farming systems approach in rainfed agriculture not only addresses income and employment challenges but also ensures food security.
