This is an in-depth study of the methods of water harvesting and conservation systems in medieval Mewar (800-1700). What use was made of collected and conserved water is extensively examined in the light of extant structures (dams, wells, step wells and tanks) supplemented by contemporary documents, historical epics, inscriptions, letters, revenue records and so on. The techniques to extract underground and use of surface water for religious as well as secular purposes such as drinking and irrigation are examined by the author. The volume also questions the statements of the British and Indian authors about the non-use of waterbodies for irrigation in medieval times, which were constructed by Sisodia rulers. The volume also delves deep into the methods of water harvesting and conservation in the urban sector. It details the efforts of the Sisodia rulers in this area to provide drinking water to the city-dwellers, besides highlighting their concern for environmental issues. This well researched study enhances our understanding of the methods of harvesting rain water and the techniques of extracting underground water and would be indispensable to researchers working on agrarian economy and environment in the Indian subcontinent.
