Traditional Water Storage and Conservation Methods in North East India – A Review
Summary
This review explores ancient and traditional water storage and conservation methods in North East India, highlighting region-specific techniques adapted to high rainfall and steep topography. Traditional systems like Apatani in Arunachal Pradesh integrate terraced plots with bamboo frames for multipurpose water management, combining irrigation, soil erosion control, and paddy-fish culture. Assam’s Dong and Jampois systems channel river water through canals and sub-channels for agriculture. Manipur employs Khong ponds and lakes, while Meghalaya uses bamboo drip irrigation and rooftop harvesting. Mizoram’s Ruza method stores water in rocks, and Nagaland’s Zabo and Cheo-ozihi systems impound runoff and channelize rivers through bamboo pipes. Sikkim’s Khola and Simsaar structures, along with Tripura’s bamboo drip irrigation, reflect indigenous innovations. These methods emphasize sustainability, community participation, and adaptation to local geomorphology, offering lessons for modern water scarcity challenges. The study underscores the historical significance of such practices, rooted in ancient civilizations like the Indus Valley, which developed advanced plumbing and sewage systems.

Conclusion
This document highlights the historical and traditional water conservation methods in North East India, emphasizing their relevance to modern challenges. It details indigenous techniques like Apatani's terraced farming in Arunachal Pradesh, Assam's Dong-Bandh system, and Meghalaya's bamboo drip irrigation, showcasing region-specific adaptations to geography and rainfall. The review also connects these practices to broader historical contexts, including ancient Indian civilizations like the Indus Valley, which pioneered advanced water management and sanitation. By documenting these methods, the study underscores their potential for addressing contemporary water scarcity and erratic monsoons, advocating for the revival and integration of traditional knowledge into modern water policies. The implications suggest that preserving such heritage can enhance water security, support sustainable agriculture, and foster community resilience in the face of climate variability.
