For instance, the stepwells or baolis in Gujarat and Rajasthan are architectural marvels designed to access groundwater during dry periods. Similarly, tanks and ponds in South India, like those in Tamil Nadu and Karnataka, served both religious and practical purposes, aiding in irrigation and groundwater recharge. These structures not only provided water for drinking but also became centers for social and cultural activities, emphasizing their significance in daily life. The impact of these water resources on the lives of local communities is profound, supporting their livelihoods, traditional practices, and community sustainability.
Traditional Water Harvesting Structures
1. Johads (Rajasthan)
Johads are earthen check dams constructed to capture and store rainwater, facilitating groundwater recharge. Predominantly found in Rajasthan, these structures have been revived in recent decades, notably by the efforts of NGOs like Tarun Bharat Sangh, leading to increased water availability and agricultural productivity in the region. These initiatives have significantly involved villagers, empowering local communities by providing them access to reliable water sources and enhancing their quality of life.
2. Khadins (Western Rajasthan)
A Khadin is an ingenious construction designed to harvest surface runoff water for agriculture. It involves building a long earthen embankment across the lower hill slopes, allowing water to collect and seep into the soil, making it suitable for cultivation.
3. Baolis and Stepwells (Gujarat, Rajasthan)
These are deep well-like structures with steps leading down to the water, providing water access even during periods of low water levels. Beyond their functional use, many baolis are architectural masterpieces, reflecting the artistry of their time. These ancient stepwells also serve as effective water storage systems, helping recharge groundwater and address modern water crises.
4. Ahar-Pynes (Bihar)
This traditional system involves diversion channels (pynes) that direct water to embanked reservoirs (ahars). It’s an effective method for floodwater harvesting and irrigation in the alluvial plains of Bihar.
5. Zabo System (Nagaland)
The Zabo system, also known as Ruza, is a unique water management practice from Nagaland. It integrates forest conservation, agriculture, and water harvesting, ensuring sustainable water supply and soil fertility.
