THE ECONOMIC WEEKLY May 9, 1953 Water Resources of and their Utilisation D N Nagar

Today, the threat of famine looms large over wide tract a of division which fall between Jai­ pur in the east and in the west. The only district which is immune is Ganganagar, which is irrigated by the canals constructed by the late Maharaja Gangasingh Even in this granary of Rajasthan, two tehsils have been declared scarcity stricken by the Rajasthan Government. rThe following account of the scarce water resources and the possibilities of their fruit fill utilisation will throw light on the causes of recurring scarcity and also indicate the lines on which remedial mea­ sures should be sought, •
