All statistical evidence confirms that agriculture is the key sector for water management, now and in the next decades. Nevertheless, the rural water development sector fails at present to get priority, compared to other competing sectors, in international fora. Strong and new arguments are needed to bring rural water back "on line." Agriculture policies and investments will need to become more strategic. They will have to unlock the potential of agricultural water management practices to raise productivity, spread equitable access to water, and conserve the natural productivity of water resources base.

Water Productivity and Food Security: Global Trends and Regional Patterns, Volume Three reviews the need for water productivity improvements in agriculture, addressing three distinct questions pertaining to agricultural water productivity improvement in developing countries, including what are the regions where water is a limiting factor for raising agricultural outputs and water productivity improvements, what are the technological measures in irrigation that can raise agricultural water productivity and result in water saving at various scales, and what opportunities exist in the developing economies of South Asia and Africa for raising water productivity and improving water economy at basin scale. This book provides a framework to characterize river basins based on water availability, water supplies, water uses and water demands to ascertain the need and measures available for improving crop water productivity that would be effective at various scales, i.e., plant-level, plot-level, irrigation system level and basin level. This is an essential reference for anyone interested in water management and agriculture. - Presents clear explanations of the physical and technical measures that can be adopted to improve productivity of water in agricultural production under different basin conditions - Offers physical strategies for improving water productivity in agriculture in different agroecological regions, along with the institutional and policy measures that affect them - Includes methodologies for assessing the food security challenges of individual nations using empirical analysis and global datasets

With Africa's water resources constantly threatened by an increasing population and the resultant rise in water demand, together with the stresses of water use for various activities, desertification, climate change, and other interventions in the water cycle by man, it is vital that the water resources in arid and semi-arid regions are developed a

The degradation of land and water resources as a result of agricultural activity has had an enormous impact on human societies and economies. It is predicted that, by 2025, most developing countries will face physical or economic water scarcity, compounded by land degradation. In order to alleviate this problem, an advanced understanding of the state of our water resources and the relationships between land use, water management and social systems is needed. Conserving Land, Protecting Water includes an overview of global patterns of land and water degradation and discusses new insights drawn from successful case studies on reversing soil and water degradation and their impact on food and environmental security.

Globalization of Water is a first-of-its-kind review of the critical relationship between globalization and sustainable water management. It explores the impact of international trade on local water depletion and pollution and identifies “water dependent” nations. Examines the critical link between water management and international trade, considering how local water depletion and pollution are often closely tied to the structure of the global economy Offers a consumer-based indicator of each nation’s water use: the water footprint Questions whether trade can enhance global water use efficiency, or whether it simply shifts the environmental burden to a distant location Highlights the hidden link between national consumption and the use of water resources across the globe, identifying the threats facing ‘water dependent’ countries worldwide Provides a state-of-the-art review and in-depth data source for a new field of knowledge

Located in a narrow grassland corridor between the semi-desert and a mountain range in Northwest China, the research area Urumqi Region is despite its semi-arid climate in a relatively favourable hydrological situation. The nearby mountains provide water for settlements and agriculture, making human development possible in the first place. Due to the development of agriculture, population and economy during the last sixty years and the increasing water consumption, a demand- and population-driven water scarcity exists today and is expected to aggravate. At the same time, the effects of climate change and land use transformations on the hydrological system and the water availability are uncertain. This study evaluates the recent and future situation by combining a hydrological water balance model for the simulation of the water supply based on scenarios of climate and land use change with a socio-economic model for projecting the future water demand including predicted growth of population and economy.

This book presents papers from an international conference, held in Bonn, Germany in February 2005, that dealt with integrated water resources management in industrialized and developing countries. The papers detail such emerging concepts as blue and green water, virtual water, the water footprints of nations, multi-agent modeling, linkages between water and biodiversity, and social learning and adaptive management.
