The results of the Assessment will enable farming communities, governments and donors to make better-quality investment and management decisions to meet food and environmental security objectives in the near future and over the next 25 years. The Research Report Series captures results of collaborative research conducted under the Assessment. It also includes reports contributed by individual scientists and organizations that significantly advance knowledge on key Assessment questions. Each report undergoes a rigorous peer-review process. The research presented in the series feeds into the Assessment’s primary output—a “State of the World” report and set of options backed by hundreds of leading water and development professionals and water users. Reports in this series may be copied freely and cited with due acknowledgement. Electronic copies of reports can be downloaded from the Assessment website (www.iwmi.org/assessment). If you are interested in submitting a report for inclusion in the series, please see the submission guidelines available on the Assessment website or send a written request to: Sepali Goonaratne, P.O.

Comprehensive Assessment Research Report 10 Cities versus Agriculture: Revisiting Intersectoral Water Transfers, Potential Gains and Conflicts François Molle and Jeremy Berkoff Comprehensive Assessment of Water Management in Agriculture i The Comprehensive Assessment (www.iwmi.cgiar.org/assessment) is organized through the CGIAR’s Systemwide Initiative on Water Management (SWIM), which is convened by the International Water Management Institute. The Assessment is carried out with inputs from over 100 national and international development and research organizations—including CGIAR Centers and FAO. Financial support for the Assessment comes from a range of donors, including core support from the Governments of the Netherlands, Switzerland and the World Bank in support of Systemwide Programs. Project-specific support comes from the Governments of Austria, Japan, Sweden (through the Swedish Water House) and Taiwan; Challenge Program on Water and Food (CPWF); CGIAR Gender and Diversity Program; EU support to the ISIIMM Project; FAO; the OPEC Fund and the Rockefeller Foundation; and Oxfam Novib. Cosponsors of the Assessment are the: Consultative Group on International Agricultural Research (CGIAR), Convention on Biological Diversity (CBD), Food and Agriculture Organization (FAO) and the Ramsar Convention. The authors: François Molle is a Principal Researcher at the International Water Management Institute, Colombo, Sri Lanka, seconded from the Institut de Recherche pour le Développement (IRD), France and Jeremy Berkoff is an Independent Economist/Water Resources Consultant.

Moving water Problems of urban water scarcity are away from agriculture to uses with higher sometimes compounded by the physical economic value is one of the main measures environment (arid climate) or by the location of widely seen as desirable. Sectoral “allocation cities in upper catchments where no large stress” is often identified as resulting from four streams are available nearby. However, most different observations: a) agriculture gets the large cities in the developing world tend to have “lion’s share” of all diverted water resources; b) deficient-to-poor water supply and sanitation agriculture is not only the main water user but facilities, even if there is abundant water in their also an activity that incurs by far the largest surroundings. As shown by the debate on wastage; c) cities are “thirsty” ; and d) water financing of water-supply infrastructure, the main productivity in nonagricultural sectors is far higher issue is “where to find the money?” rather than than in agriculture. This apparent misallocation is “where to find the water?” It is shown that urban often attributed to the failure of the government to water supply is a reflection of the local political allocate water rationally. economy where the “threat from below” (voice of This report revisits this commonly-accepted civil society, popular unrest, epidemics, etc.,) the wisdom and examines the nature of urban water financial and political benefits accruing to the scarcity, the relative importance of both physical elites and decision makers, and the possibility to and economic scarcity, and how cities secure tap financial resources (through privileged funds for the development of their water relations with the central government or infrastructure (or fail to do so).
