"This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is an important source for irrigated agriculture as it generally furnishes reliable and flexible inputs of water. To this extent, groundwater is instrumental in managing risk and optimizing food production. However, this reliance upon shallow aquifer systems for irrigation has turned to dependency. Competition for groundwater is intense both between neighbouring users and among economic sectors. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management."--Preface.

This book provides an overview, by leading world experts, on key issues in global water and food security. The book is divided in a series of over-arching themes and sections. The first part of the book provides an overview of water and food security. The second and third sections look at global trade and virtual water trade, and provide some specific examples on the application of the water footprint at different scales. The fourth section sets the context into wider debates related to global sustainable production and consumption. The last section of the book addresses the role of the silent groundwater revolution to help address water and food security; the water/energy nexus, and the potential for generating ́new ́ water.

If irrigated production is to make a significant contribution to food security and economic growth in Sub Saharan Africa, it will have to be re-structured across the region as a whole. This is the main conclusion of a study undertaken by FAO to analyse the drivers of demand for irrigated production in Sub-Saharan Africa (SSA). Steeply rising commercial food import bills for staple crops across SSA are indicative of the level demand that is not being met from domestic production. The increase of area under equipped/spate irrigation for the whole of Africa over the last ten years amounts to 1.27 million ha, which is equal to about 127 000 ha a year. This rate of growth has proved too low to have an impact on food import bills and buffer regional food security. However, within subregional trading groups there is scope for consolidation of market supply. Irrigated production opportunities in SSA could be realised where natural resources and markets coincide, but only through a great deal more attention to costs of production, price formation, effective water allocation mechanisms, economically efficient water use and strong, responsive institutions.--Publisher's description.

The impacts of climate change on the global hydrological cycle are expected to vary the patterns of demand and supply of water for agriculture--the dominant use of freshwater. This report summarizes knowledge of the anticipated impacts of climate change on water availability for agriculture and examines the implications for local and national food security. It analyzes expected impact of climate change on a set of major agricultural systems at risk and makes the case for immediate implementation of "no-regrets" strategies which have both positive development outcomes and make agricultural systems resilient. It is hoped that policy makers and planners can use this report to frame their adaptation responses when considering both the water variable in agriculture and the competing demands from other users.

The quality and availability of fresh water are of critical importance to human and ecosystem health. Given its central role in the functioning of all living systems, water is arguably the most important of all natural resources. Produced biennially, The World's Water provides a timely examination of the key issues surrounding freshwater resources and their use. Each new volume identifies and explains the most significant current trends worldwide, and offers the best data available on a variety of water-related topics. This 2004-2005 edition of The World's Water features overview chapters on: conservation and efficiency as key tools for meeting freshwater needs; bottled water quality, costs, and trends; United Nations millennium development goals; groundwater issues; case studies of water privatization; the economic value of water; California water policy and climate change. The World's Water is the most comprehensive and up-to-date source of information and analysis on freshwater resources and the political, economic, scientific, and technological issues associated with them. It is an essential reference for water resource professionals in government agencies and nongovernmental organ-izations, researchers, students, and anyone concerned with water and its use.

The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 22 countries of the Southern and Eastern Asia region, and it analyzes the changes that have occurred in the ten years since the first survey. Following the AQUASTAT methodology, the survey relied as much as possible on country-based statistics and information.

The Pacific developing member countries (DMCs) of the Asian Development Bank (ADB) are a diverse array of countries with widely varying topographies, cultures and economies, fragile natural resource environments, and prosperity, stability, and security that can be compromised by the impacts and consequences of climate change. The Pacific island governments view climate change as a priority issue, especially in terms of its potential impacts on food security, and need clear directions in addressing both issues. This report describes the present state of food security and its contributing factors in the Pacific region, assesses its prospects amid the growing threats and likely impacts of climate change, and presents potential areas for more active assistance, investments, and interventions from ADB and other development partners. While technical and policy measures to ensure food security amid the ensuing climate change are numerous, interrelated, and complex, the successful implementation of programs and projects calls for simple and flexible designs that carefully consider the capabilities of relevant stakeholders at the regional, national, and local levels.

In recent times, the coalescence of different pressure has put a major strain on water supply globally. The level of water abstraction is reaching its natural limits, and this calls for a dramatic shift in water utilization concepts. This publication addresses the economic and financial issues and the methodology and procedures involved in the analysis of water recycling projects as part of a comprehensive water planning process. The issue is dealt within the wider context of water resources and covers human health, water quality, acceptability, institutional constraints, and other factors, all of which have economic implications and affect the feasibility of reuse schemes. The recycling of urban wastewater is a key link in integrated water resource management (IWRM) that can fulfill several different, but interrelated objectives. These are expressed as win-win propositions, delivering simultaneous benefits to farmers, cities and natural environmental systems, part of solutions to the urgent global problems of food, clean water, the safe disposal of waters and the protection of the vital aquatic ecosystems.--Publisher's description.
