Revival of Ancient Ahar-Pyne System to Combat Drought in South Bihar

To combat the recurring issue of drought in South Bihar, the state government has launched a project to revive the ancient Ahar-Pyne irrigation system. This traditional water harvesting method, which dates back to the Magadhan empire of Chandragupta Maurya, is a network of channels (pynes) that divert river water into large earthen reservoirs (ahars). This is a key strategy for managing the Rivers of Bihar. The system is particularly relevant for districts in the Magadh Division. The system is designed to capture monsoon runoff, recharge groundwater, and provide a reliable source of irrigation for crops during dry spells. Over the centuries, many of these structures fell into disrepair. The revival project involves desilting the channels, strengthening the embankments of the reservoirs, and integrating them with modern water management techniques. This initiative, particularly active in districts like Gaya and Nawada, is expected to significantly improve agricultural productivity and enhance the region's resilience to climate change. It represents a blend of traditional wisdom and modern science to address contemporary environmental challenges, a different approach to managing the Rivers of Bihar.
