FOREWORD The water challenges and issues faced by Spain are At the request of the Government of Spain, the World unique in Europe but are highly relevant to the rest of Bank provided technical expert assistance for the policy the world. Precipitation is highly variable in space and and technical content of the Water Tribune and time, with regions where it rains more than 2,000 mm identified key representative participants from client per year, while others, such as Almeria, host one of the countries for two Technical Visits and 14 Global few deserts in Europe. This climatic variability has been Development Learning Network (GDLN) sessions overcome by building innovative water infrastructure guided by the World Bank Institute that took place and by establishing highly advanced and specialized throughout the three months of the World Water Expo. Hydrographic Confederations (Confederaciones The inclusion of the two technical visits was considered Hidrográficas), which are the oldest river basin very timely to learn from Spain’s rich water resources management authorities in the world. An example of management experience. In both technical visits, such infrastructure works includes the 2,000-year-old participants toured the Ebro Hydrographic Confederation Cornalvo reservoir, which is still in operation. As for the (CHE), where one of the highlights was to learn about institutions, special mention should be made of the the operation of the Automatic Hydrological Information Irrigation Associations, some of which have existed for System that the CHE has put in place. The Canal de more than a thousand years, and the Hydrographic Isabel II in Madrid, one of the oldest utilities in the world, Confederations, which are the oldest river basin was also visited in one of the tours, providing the management authorities in the world. participants with an array of technological and organizational insights; unlike many utilities, the Canal The city of Zaragoza, located by the Ebro River, was an manages the full water cycle. The second visit allowed ideal setting for Expo Zaragoza 2008, the international the group to see examples of conjunctive use of exhibition organized by the Government of Spain from desalinated water with groundwater in Almeria in June 14 through September 14, 2008. Like no other, southern Spain. Highlights of the visit were the water this 700 million Euro event was fully dedicated to water metering and remote management systems in irrigated and sustainable development and was set to attract areas under greenhouses, the organization of water user about 6 million visitors, 20 percent of whom were associations, and the operation of a desalination plant. expected to be from other countries. In one of its key components, the Water Tribune, relevant world national The “Spanish Model” offers many worthwhile and international water professionals from governments, experiences that are highly relevant and applicable to academia, civil society, and the private sector met to the realities faced by many developing countries. We discuss sustainable initiatives and solutions to the many are thus pleased to present this report, which challenges facing water management around the globe. summarizes relevant aspects of the water knowledge shared by Spanish water experts and those from the Bank’s client countries during the Water Tribune and the technical visits.
