This book is the latest in a long line of Economic Commission for Latin America and the Caribbean studies on water resources in Latin America and the Caribbean which focus on questions relating to the management of water resource systems.

Approximately 80 per cent of the population of Latin America is concentrated in urban centres. Pressure on water resources and water management in cities therefore provide major challenges. Despite the importance of the issues, there has been little systematic coverage of the topic in book form. This work fills a gap in the literature by providing both thematic overviews and case study chapters. It reviews key aspects of why water matters in cities and presents case studies on topics such as groundwater management, green growth and water services, inequalities in water supply, the financing of water services and flood management. Detailed examples are described from Argentina, Brazil, Colombia, Ecuador, Mexico and Peru, and there is also a chapter comparing lessons which might be learnt from US cities. Contributing authors are drawn from both within and outside the region, including from the Inter-American Development Bank, OECD and World Bank to set the issues in a global context.

Climate change is the defining development challenge of our time. More than a global environmental issue, climate change and variability threaten to reverse recent progress in poverty reduction and economic growth. Both now and over the long run, climate change and variability threatens human and social development by restricting the fulfillment of human potential and by disempowering people and communities in reducing their livelihoods options. Communities across Latin America and the Caribbean are already experiencing adverse consequences from climate change and variability. Precipitation has increased in the southeastern part of South America, and now often comes in the form of sudden deluges, leading to flooding and soil erosion that endanger people s lives and livelihoods. Southwestern parts of South America and western Central America are seeing a decrease in precipitation and an increase in droughts. Increasing heat and drought in Northeast Brazil threaten the livelihoods of already-marginal smallholders, and may turn parts of the eastern Amazon rainforest into savannah. The Andean inter-tropical glaciers are shrinking and expected to disappear altogether within the next 20-40 years, with significant consequences for water availability. These environmental changes will impact local livelihoods in unprecedented ways. Poverty, inequality, water access, health, and migration are and will be measurably affected by climate change. Using an innovative research methodology, this study finds quantitative evidence of large variations in impacts across regions. Many already poor regions are becoming poorer; traditional livelihoods are being challenged in unprecedented ways; water scarcity is increasing, particularly in poor arid areas; human health is deteriorating; and climate-induced migration is already taking place and may increase. Successfully reducing social vulnerability to climate change and variability requires action and commitment at multiple levels. This volume offers key operational recommendations at the government, community, and household levels with particular emphasis placed on enhancing good governance and technical capacity in the public sector, building social capital in local communities, and protecting the asset base of poor households.

Integrated water resources management advocates a coordinated approach for managing water resources in a way that balances social and economic needs with concern for the environment. While potentially useful, integrated water management is also controversial. Supporters believe that the multi-dimensional nature of water can only be understood and managed from a holistic perspective, while critics often argue that integrated water management lacks suffi ciently well-defi ned rules for its practical implementation. This book, written by academics, users and practitioners, provides a down-to-earth approach to the ideal of integrated water resources management, drawing from conceptual frameworks and real-life practice to identify the key aspects that are yet to be resolved. As such, it examines the role of water accounting, food trade, environmental externalities and intangible values as key aspects whose consideration may help the water management community move forward. Overall, integrated water resources management is perceived to be a useful utopia, whose value lies more in the steps that need to be taken to make it a reality than in achieving its ever-elusive end goal.
