No grain is ever produced without, but too much water tends to spoil the grain". Good management, efficient and effective resources utilization, and operation and maintenance of drainage and irrigation systems within a given watershed are the key essential factors to the success and sustainability of irrigated agriculture. The book on "Managing Drainage and Irrigation" is a compliation of papers closely linked with the experiences during the period 1960 to 1996 (and more particularly 1974 to 1996) of the Command Area Development Authority (CADA) in the development and management of drainage and irrigation system in the Chambal Command Area (CA) in the state of Rajasthan, India. An attempt has been made not only to provide case study of the Chambal CAD Project as regards irrigation, drainage, on farm development and Command Area Development activities, but also to highlight issues of managing drainage and irrigation systems which may provide insight for persons working in the similar projects the word over. This book will be useful as a reference sources to the students, researchers, teacher administrators, managers and policy makers on drainage and irrigation. It should appeal to the technocrat, the social scientists, the bureaucrat manager and the inequisitive citizen.
