Irrigation management for agriculture and rural development has a long history in South Asia, yet today it asserts a critical paradox: new scarcities are emerging, but irrigated agriculture still contributes vitally to food security and agro-industries. This collection of case studies from India and Nepal shows how irrigation management operates across complex dynamics of ecology, technology, and society, documenting interdisciplinary research approaches to study these.

Irrigation management for agriculture and rural development has a long history in South Asia, yet today it asserts a critical paradox: new scarcities are emerging, but irrigated agriculture still contributes vitally to food security and agro-industries. This collection of case studies from India and Nepal shows how irrigation management operates across complex dynamics of ecology, technology, and society, documenting interdisciplinary research approaches to study these. It takes the reader through irrigation technologies developed in different agro-ecological zones: large-scale public canal systems in semi-arid zones; small-scale farmer-managed canal systems in hill environments, ponds, and tank irrigation systems; and groundwater-based systems developed from borewells and in conjunctive use settings. It also includes a study of micro-hydel systems developed alongside irrigation. The case studies analyse these technologies in relation to processes of change through public policy and local action. They examine the design choices of irrigation agencies and farmers in irrigation provision, and show the forces of agrarian change acting on water access, property rights, and water institutions. Some review recent state policies for reforming irrigation management that introduce new organizational forms, but also promote markets and cost recovery. In this way, the volume documents the wider development policies acting onto irrigation management. The volume offers new scientific understanding of the complex interrelationships between water as a crucial resource in irrigation-based livelihoods, and the technologies and institutions that regulate its use. For emerging questions of equitable access to water and water productivity in South Asia, such interrelated understanding of technology and institutional choices is fundamental.
