Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.

"In order to face the challenge of disappointing returns on public investment in irrigation and drainage new solutions have emerged. These solutions are based on widely available technology and new management and governance options. The main message of Re-engaging in Agricultural Water Management is that the irrigation and drainage sector should not continue to be dealt with as a standalone sector, but should be integrated into a broader perspective, one that embraces the objectives of productivity growth, poverty reduction, natural resources management and environmental protection."

In many developing countries, their governments dominate the field of water resources management. Even in “participatory irrigation management” efforts, the governments play a dominant role. As these efforts are rarely based on any internally generated demand from the water users, they usually fail to create viable organizations at the local level. A similar setback can be seen in the more recent institutional reforms in Asia’s water sector, which are promoted by the donor agencies and, national and international development professionals. A survey of experiences in Asian countries shows that no country has successfully completed establishing new water sector policies and laws and river basin organizations, as prescribed. The need to improve current performance of water resources management is widely appreciated.In managing the scarce water resources, a change in attitude and approach is seen to be essential. Participatory learning and action methods conducted in a study of selected river basins in five Asian countries surfaced a distinct need for coordination at the river basin level. They also indicated a clear stakeholder preference for establishing coordinating mechanisms, by way of adapting the existing institutions, as an initial step towards greater stakeholder control of river basin management. Essentially, cost-effective and contextually appropriate institutional arrangements were preferred over the prescribed standard models, in order to meet the varying needs related to integrated water resources management.
