India’s agrarian foundation rests upon its soil and water resources, both of which are increasingly threatened by overexploitation and climate variability. Integrated Water Management (IWM), particularly through watershed development programs, offers a holistic and sustainable response. This article examines how IWM - through rainwater harvesting, soil conservation, afforestation, and community involvement—has revitalized degraded lands and enhanced agricultural productivity. Drawing from successful interventions across drought-prone regions, the analysis demonstrates significant gains in water availability, crop yields, and rural livelihoods. The paper underscores the urgency of mainstreaming IWM to secure India's ecological and socio-economic future.
