Book Description
Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.

Book Description
This policy guide is drawn from the results of the FAO Project “Strengthening Agricultural Water Efficiency and Productivity at the African and Global Level” funded by the Swiss Agency for Development and cooperation (SDC). The long term vision of the project was that the in-country findings and processes which are of common nature can be synthesized and scaled up to other countries in a regional cooperation process and globally. This will eventually lead to the increase of investment in Agricultural Water Management (AWM) in the targeted countries – and beyond – that is socially equitable, profitable at the farm level, economically viable, environmentally neutral or positive, and sustainable. The Guide focuses on the specific component of Enhancing Water Use Efficiency at small scale irrigation as one of the major outputs of the project. While creating and implementing Water Use Efficiency (WUE) measures at field level, existing policy frameworks were mapped and analyzed, and recommendations were defined as scalable policy instruments with the aim to demonstrate case-specific experiences to the collectively agreed goal of using water resources efficiently.

Book Description
Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.

Book Description
This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Book Description
Between the years 2000 and 2025 the world?s population is expected to rise from six billion to about 8 billion. At the present time, irrigated agriculture provides one third of world food output. So the advance of the irrigated sector on a global scale is a vital part of the development of the human race's capacity to feed itself. This requires many skills, including an economic understanding of the role of water in the irrigation and drainage of farmland. The purpose of this book is to provide a text in securing such an understanding that will assist both students and professionals in the fields of agriculture, development studies, geography, hydrology and planning. As an introduction to the subject, no prior knowledge of economic theory is assumed. The scope of the book is wide both in its analysis and its geographical coverage. A general introduction to irrigation and to economics is followed by a treatment of farmer’s need for irrigation water and the costs they face in accessing it. Three chapters cover the supply-side: infrastructure, operation and maintenance. An introduction is next given to the economic evaluation of irrigation and drainage projects continuing with a consideration of water allocation between sectors at the regional level. The book ends with a summary of the analysis as well as sixteen proposals for policy development. The approach is to make it possible for readers from a variety of backgrounds to readily access the subject matter. Each chapter begins with general, analytic themes and is followed by one or two detailed case studies drawn from Australia, Brazil, England, India, the Mediterranean, Mexico, Pakistan, Palestine, the Philippines and the USA. The desire is to continually interrelate theory and fieldwork in an argument that is clearly expressed, well-structured and as easy to read as the subject permits. The book is the first of its kind published since 1981.

Book Description
The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts have
