Forming the 10th volume from this successful international conference series, this book presents the work of scientists, practitioners and other experts regarding recent technological and scientific developments associated with the management of surface and sub-surface water resources.

The performance of the International Food Policy Research Institute’s (IFPRI’s) research program that focuses on water resource issues is reviewed for the period 1994–2010 around the three themes that constitute the program: global modeling, river basin modeling, and institutions. The IFPRI water team has been involved in leading-edge research in a number of dimensions: it has focused on analysis at varying geographic scales; the work has been truly interdisciplinary by engaging economics with biophysical science and other social sciences; and research outputs have been innovative in advancing institutional analysis and water pricing and in policy measures addressing the complexities of water supply management. In the research tasks, IFPRI’s water team actively collaborated with a wide range of researchers from within the CGIAR network, national research institutes, and universities. Within the team, a largely stable group of leaders has been responsible for the professional development of a substantial cohort of junior staff who have moved onto successful careers elsewhere. The output of the program has been prolific and prominent in academic, policy, and development communities. The approach taken is to review selected publications from the themes; assess the quality of the journals in which papers have been published; and evaluate the performance, on average, of researchers in the program. In addition, surveys of stakeholders were carried out, and three specific projects were subjected to detailed review. The assessment demonstrated the high regard in which the program research outputs and researchers are held. The IFPRI water team has been remarkably productive throughout the 16 years considered, working on issues that are of high relevance to policy and producing work that has largely been cutting edge. However, impacts generated by individual projects were not consistently or readily identifiable. To maximize the benefits of this performance and to overcome challenges associated with securing more outcomes, this report recommends that a more coordinated approach be taken to develop the research project portfolio. This would involve better targeting of projects to policy objectives through a more systematic review of research demand forces and improved integration of research work with policy development processes. The latter in particular requires the development of a sense of research project “ownership” within the policy circles the research is designed to influence. More effort in the development of in-country research partnerships can aid this process as local researchers can act as “champions” within local policy circles. Where government agencies have a research function, their integration into the partnerships is recommended. Avoidance of completing research projects in a “policy vacuum” is critical but requires both advanced planning of each research project as well as constant adaptation of the work plan to (often rapidly) evolving policy contexts. To achieve project impacts beyond the immediacy of the specific case study context, a more targeted and coordinated publication strategy should be developed in light of changing publication technology. Project webpages within the IFPRI website, with readily downloadable reports, are useful during the implementation of each project and more formal papers should be targeted for publication in high-impact factor technical journals with parallel papers prepared for more policy-oriented journals that have high circulations.

Over the past few years on-site sanitation has been widely promoted as a solution which can be quickly implemented to address sanitation issues, and it is gaining traction. As such, treatment of the contents emptied from on-site containments has become a pressing issue. While dedicated treatment facilities for this purpose have been advocated, co-treating these wastes in sewage treatment facilities is a promising option, which many countries have implemented or are exploring. This option maximises the utilisation of city infrastructure. In cases where the existing sewage treatment facilities are underutilised, co-treatment presents a ready solution for managing fecal sludge and septage. In spite of co-treatment being a well-known practice in many countries, it remains clouded in uncertainty, especially regarding the technical advisability, and potential risks of co-treating fecal sludge or septage in sewage treatment plants. Planners and decision-makers are often very apprehensive in considering co-treatment. As a result, the opportunity to better utilise available infrastructure for co-treatment of sludge is often being missed. Meanwhile, there are also many cases where co-treatment has been tried, either successfully or otherwise, but it has not been possible to draw conclusions from these, to guide the way forward. This guide book explores some of the basic principles behind sewage treatment, and how it may be impacted by co-treatment of wastes from on-site containments, to try to throw some light on how co-treatment could be considered, in an incremental manner, recognising risks and mitigating them. It is intended to facilitate a better understanding among planners, engineers, decision makers and technical practitioners and to help them evaluate and consider the option of co-treatment.

Economical, Political, and Social Issues in Water Resources provides a fully comprehensive and interdisciplinary overview of all three factors in their relation to water resources. Economic issues consist of Water accounting, Water economy, Water pricing, Water market, Water bank and bourse. Political issues consist of Water power and hydrogemistry, Water diplomacy and hydropolitics, Water rights and water laws, Water governance and policy, Shared water resources management, Water management systems, and social issues consist of Water and culture, civilization and history, Water quality, hygiene, and health, Water and society. This book familiarizes researchers with all aspects of the field, which can lead to optimized and multidimensional water resources management. Some of abovementioned issues are new, so the other aim of this book is to identify them in order to researchers can easily find them and use them in their studies. - Includes diverse case studies from around the world - Presents contributions from global and diverse contributors with interdisciplinary backgrounds, including water engineers, scientists, planners the economic, political and social issues surrounding water - Contains in-depth definitions and concepts of each topic

This cutting-edge Handbook provides a global perspective on the current issues affecting water politics and governance. Focusing in particular on the policy-making process and the power dynamics that it involves, it showcases the emerging diversity of objectives, instruments and governance approaches in the field of water resources.
