The U.S. Army Corps of Engineers, through its civil works program, can take pride in its contributions throughout our nation's history to the development of waterways infrastructure, navigation, flood damage reduction, water resources development and protection, and environmental restoration. Many projects that have been pioneering in their concept and bold in their execution were made possible by the creativity and dedication of outstanding scientists, engineers, and builders. The Corps has always had review processes for evaluation of its planning studies and projects, with the focus often being largely on the technical aspects. In recent years, however, increased consideration of such factors as environmental impacts, economic evaluations, political pressures, and new paradigms about flood control and management has engendered increased criticism and concern that some of the Corps' studies may have led to conclusions, recommendations, and project decisions that are not adequately supported by the assumptions and analyses that were used. The focus of the report is on review of Corps of Engineers studies, with careful attention given to the need for independent, external reviews by panels of well-qualified and impartial experts for large, complex, and sensitive projects.

The book includes seventeen excellent researched and documented papers that reflect the diversity of thought, ideas and experiences related to IWRM. They draw from an extensive, inclusive and geographically representative range of theoretical propositions and practical examples. These include the implementation status of the IWRM concept at local, basin, regional and national levels; its appropriateness for the twenty-first century; main implementation gaps from the institutional, legal, policy, governance, management and technical viewpoints; the likelihood that IWRM’s entrenchment in laws, regulations and policies has led to smoother implementation and the reasons why that has been the case; reflexions on whether the attention given to IWRM is pushing other alternatives to the policy periphery; and the new conceptual constructions that can be put forward for discussion in the international arena. For the development and water communities it is imperative to debate and reach towards more illustrative conclusions regarding whether the promotion of the IWRM concept and its actual implementation status have been beneficial for development and how the notion could evolve to achieve this end. In-depth objective and constructive discussions, arguments, proposals and ideas are put forward for analysis by all interested parties. The book has the objective of fostering scholarly exchange, encouraging intellectual debate and promoting the advancement of knowledge and understanding of IWRM as a concept, as a goal per se and as a strategy towards development goals. This book was published as a special issue of the International Journal of Water Resources Development.

This report calls on policy makers to recognise the issues at stake in water resource management in agriculture and gives them the tools to do so, offering a wealth of information on recent trends and the outlook for water resource use in agriculture.
