Ranchi, Sept. 19: Jharkhand receives a good rainfall but in the absence of a water conservation system, the water drains out. Hence, water conservation methods, like rainwater harvesting, are needed to increase awareness among masses. These points came to the fore during a seminar on the status of water conservation and its importance in agriculture today. The two-day seminar began at Indian Natural Resins and Gums Institute, Namkom, on the eve of its 85th foundation day. Bangali Baboo, the institute director, pointed out that around 26 lakh hectares in the state are lying neglected, which can be utilised for cultivation.
