Book Description
A global estimate of the potential for rain-fed agriculture could provide an answer to the question “How much irrigation is required?” Global studies done to date have relied on course resolution climate data (0.5-1 degree arc). In this study a high-resolution climate dataset (10-minute arc) was combined with a soil water storage capacity map and a dynamic water and crop model to estimate the potential for rain-fed agriculture. The methodology applied here, based ona high-resolution climate dataset, allows analyses on a global scale without losing the smaller regional-scale issues.

Book Description
Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.

Book Description
First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Book Description
The supply and management of fresh water for the world’s billions of inhabitants is likely to be one of the most daunting challenges of the coming century. For countries that share river basins with others, questions of how best to use and protect precious water resources always become entangled in complex political, legal, environmental, and economic considerations. This book focuses on the issues that face all international river basins by examining in detail the Nile Basin and the ten countries that lay claim to its waters. John Waterbury applies collective action theory and international relations theory to the challenges of the ten Nile nations. Confronting issues ranging from food security and famine prevention to political stability, these countries have yet to arrive at a comprehensive understanding of how to manage the Nile’s resources. Waterbury proposes a series of steps leading to the formulation of environmentally sound policies and regulations by individual states, the establishment of accords among groups of states, and the critical participation of third-party sources of funding like the World Bank. He concludes that if there is to be a solution to the dilemmas of the Nile Basin countries, it must be based upon contractual understandings, brokered by third-party funders, and based on the national interests of each basin state. “This excellent book makes a significant contribution to the rational discussion of Nile conflicts and should be helpful to many of the other 282 international river basins facing similar problems.”—Peter P. Rogers, Harvard University

Book Description
While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Book Description
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.

Book Description
This is the first report to systematically evaluate and quantify the economic potential of Area C, which constitutes approximately 61 percent of the West Bank. The report reveals that lifting the restrictions on economic activity in Area C could have a large positive impact on Palestinian GDP, public finances, and employment prospects. Among other things, access to economic activity in Area C is expected to be a key prerequisite for building a sustainable Palestinian economy. However, full potential of the Area C could be materialized only if other restrictions on free movement of goods, labor and capital are removed and the overall business environment in Palestinian territories has become more attractive. The economic significance of Area C lies in that it is the only contiguous territory in the West Bank, which renders it indispensable to connective infrastructure development across the West Bank, and a relative abundance of natural resources situated therein. Area C offers large potential for the development of several sectors of the Palestinian economy: agriculture, stone and mineral processing, cosmetics, construction, tourism, and telecommunications. The report shows that access to economic activity in Area C could increase the Palestinian GDP by as much as 35 percent, the majority of this impact would stem from agriculture and Dead Sea minerals processing industries, as well as the multiplier effect, which has been estimated at 1.5. Although the importance of building connective infrastructure through Area C is discussed in the report, the quantification of this impact is beyond the scope of this report. An increase in GDP of 35 percent, although thought to be a conservative estimate, would be expected to result in at least $800 million increase in tax revenues for the Palestinian authority, which would drastically reduce its dependence on donor aid for financing chronic budget deficits.
