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
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
At last, integrated management of drought on farms is dealt with in one comprehensive book. Although drought is a highly variable, near-universal natural phenomenon which has repercussions on a country's water and food supplies and many other sectors of the economy, there are many ways of avoiding, resisting and mitigating the effects of drought. Pro-active preparedness entails using the principles of risk management to upgrade the drought resistance of a farm systematically, and to have auxiliary contingency plans at the ready for use during unusually long droughts. The book provides tools for these strategies as it covers the management of water, soils, crops, rangeland, fodder and livestock, and many other drought-related topics. Audience: This book will be an important source of information for university and college staff and students in agricultural sciences, water and land use, environmental management, geography and risk management, and also farmers, agricultural advisors and policy makers.

Book Description
Englische Version: Water shortages caused by persistent and severe droughts and changes in rainfall patterns are expected to be more frequent and intense due to climate change, increasing water competition and posing food production at risk. Therefore, sustainable and resilient food systems are needed to meet the demand of a growing population. Plant production and animal husbandry account for 72% of the water withdrawn worldwide. Most water consumed in livestock production is for animal feed production. Water is also needed to provide drinking water and to clean and cool the stables. In this context, increasing agriculture and livestock water productivity (WP) is crucial, along with integrated management and governance of water resources. WP describes the ratio of output (e.g. kg milk) to water input (e.g. m3 evapotranspiration). Water input includes direct (e.g. water intake) and indirect (e.g., water for purchased feed) water use. WP calculations are used primarily in evaluating agricultural measures to improve rainfall and technical WP in livestock and crop production. Consistent methods are needed to increase WP and also to reduce the water-related environmental impact of livestock systems. Recently, the Food and Agriculture Organization of the United Nations (FAO), through the Livestock Environmental Assessment and Performance (LEAP) Partnership, launched reference guidelines for assessing water use in livestock production systems and supply chains. The FAO LEAP guidelines aim to understand the water flows on a farm scale and evaluate the contribution of livestock activities to water scarcity, supporting the identification of opportunities to reduce the potential water use impacts in this sector. This cumulative thesis presents the results of the first application of the FAO LEAP guidelines on farms located in Brazil. Three original publications were published in peer-reviewed journals.
