Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI’s long-term research goal: to determine the extent and depth of water scarcity, its consequences for individual countries and what can be done about it.

A review of global water demand projections (WDPs) show substantial over- or under-estimation. The pre-1990 WDPs, with population as the main driver of change, over-projected current water use by 20 to 130%. The post-1990 WDPs, with sophisticated modeling frameworks, show substantial underestimation under the ‘business-as-usual’ scenarios and are more downward biased under sustainable scenarios. Overall, the value of long-term country-level projections in global WDPs is inadequate for local water resource planning. To increase the accuracy and value of global WDPs, future WDPs should take into account the spatial variation and influence of rapidly changing key exogenous and endogenous drivers of water demand in different sectors across and within countries, and provide a sensitivity analysis of projections.

More than a billion people cannot get safe drinking water; half the world's population does not have adequate sanitation; within a generation over three billion will be suffering from water stress. This text analyzes the issues in this crisis of management and shows how water can be used effectively and productively. The key to sustainable water resources is an integrated approach. The authors assert that careful planning and concerted action can make the fundamental changes needed and that the implications of not dealing with the crisis are immense. The book comes with a CD ROM containing background research and scenarios.

This compendium of entries provides thematic and country perspectives to create a picture of the concerns of modern economics in Africa, with contributions from more than 100 leading economic analysts of Africa.

Provides the tools that allow companies to understand the fundamental concepts of water resource management and to take proper action towards sustainable development Businesses, communities, and ecosystems everywhere depend on clean freshwater to survive and prosper. When the same source of water is shared for economic, social, and environmental causes it becomes the responsibility of every sector to develop a sustainable water strategy beneficial for all. This book offers a water resource management plan for industries that is directly implementable and consistent with the Water Framework Directives of different countries with a special emphasis on developing countries—a plan that is economically efficient, socially equitable, and environmentally sustainable. Industrial Water Resource Management, Challenges and Opportunities for Efficient Water Stewardship offers explicit technical and investment solutions, socioeconomic and legal instruments, and recommendations for institutional restructuring. Written by a leading world expert in the field, it covers a wide range of topics including: ● Source water assessment and protection ● Water audit, industrial water footprint assessment—an evaluation of tools and methodologies ● Corporate water disclosure methods and tools ● Water stewardship by the industries ● Stakeholder collaboration and engagement ● New technologies enabling companies to better manage water resources Given the well-known challenge of managing natural resources in a way that maximizes and sustains social welfare, this book provides an invaluable point of reference for applied researchers and policy makers working in water resources management.
