South Asias story has always been shaped by water. From the great river basins that sustain billions of lives to the seasonal monsoons that define agricultural cycles, water is at the heart of the regions development, culture, and survival. Yet today, South Asia faces an unprecedented water crisis. Rapid population growth, competing demands from industrial, agricultural, and domestic sectors, and the growing impacts of climate change have created complex challenges around water availability, security, quality, equity, and conflict. These challenges do not respect national borders and demand regional, interdisciplinary, and collaborative responses. It was against this backdrop that SaciWATERs, the South Asia Consortium for Interdisciplinary Water Resources Studies, was established following the 2000 World Water Forum at The Hague. Founded on the theme of water for food and rural development, SaciWATERs set out to bring a new paradigm to water resources management in South Asia, one grounded in interdisciplinary research, gender sensitivity, and community centered action. Based in Hyderabad, India, SaciWATERs brings together accomplished scholars, researchers, and activists from Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. Through education, research, and advocacy, we generate new knowledge and build the capacity of a new generation of water professionals equipped to address South Asias most pressing water challenges.
