Indigenous systems of water governance have long shaped relationships between communities and their environments in the hill regions of Northeast India, where springs are the main source of water for daily livelihoods. In the Jampui Hills of Tripura, the Mizo community has maintained distinctive ways of governing springs and water resources through customary institutions, shared labour, cultural norms, and indigenous ecological knowledge. This paper explores how indigenous governance of water functions among the Mizo of Jampui Hills, paying attention to everyday practices through which access, care, and responsibility are organised at the community level. Drawing on secondary literature, ethnographic writings on Mizo society, and selected government and policy documents, the paper begins by situating indigenous water governance within the ecological and hydrological setting of the Jampui Hills. It highlights the dependence of local communities on spring-based water systems and examines indigenous understandings of springs, including knowledge of seasonal flows, recharge patterns, and the protection of surrounding catchment areas. Such knowledge continues to guide everyday practices of water use and conservation. At the heart of indigenous water governance in Jampui Hills are village-level Mizo institutions and customary authorities that oversee the collective management of springs. Access to water, maintenance of sources, and the resolution of disputes are regulated through shared norms, moral expectations, and cultural beliefs, including taboos against pollution and misuse. Springs are thus treated as communal resources rather than as privately owned assets. Hnatlang (regular collective labour), organised within the village, plays a crucial role in cleaning, protecting, and sustaining water sources, reinforcing a strong sense of shared responsibility. The paper also considers how recent changes in land use and livelihoods, particularly the gradual shift from shifting cultivation to horticulture and other commercial practices, have affected local water systems and increased pressure on springs. These changes are further complicated by climate variability and deforestation, which have altered rainfall patterns and contributed to the drying of once-perennial springs. While various development initiatives have been introduced to address emerging water shortages, indigenous practices of governance continue to play a central role in everyday water management in the Jampui Hills. The paper argues that indigenous governance of water among the Mizo represents a resilient and context-specific approach to water management, rooted in long-standing social relations, cultural values, and ecological knowledge. By giving importance to indigenous practices and perspectives, the study contributes to wider discussions on water governance, commons management, and indigenous knowledge systems. It also highlights the importance of recognising and strengthening community-based approaches to water governance in ecologically fragile hill regions such as Tripura.
