Advances in Irrigation, Volume 4 covers articles on the development and management of irrigation. The book presents articles on the improved method for distributing water in furrows, termed cablegation; the analysis of drip irrigation design based on the criterion of statistical uniformity; and the spatial distribution of water in sprinkling-irrigation systems. The text also includes articles on the critical evaluation of crop yields as influenced by irrigation uniformity; the concept of evapotranspiration from the scale of a field to the scale of an entire region; as well as the drainage of irrigated lands under sequential water application. Articles on the comparison of several models for the purpose of appraising the effect of irrigation on wheat and barley yields and on the economics of kiwifruit production under irrigation in New Zealand are also encompassed. The book concludes with an article about the modification and testing of a model simulating root and shoot growth as related to soil water dynamics. Agriculturists, agricultural engineers, and hydrologists will find the book invaluable.

Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.

Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.

Water scarcity has become one of the greatest challenges facing humankind today. Its scarcity is compounded by climate change and increasing demand from a growing population. In South Africa, over 60% of the available freshwater resources are used in agriculture, mainly in irrigated agriculture. There is an urgent need to promote sustainable irrigation technologies that optimize food production without increasing water applied and with positive environmental spinoffs. Sustainable irrigation technologies and practices could enhance water use efficiency (WUE) and productivity in agriculture and reduce environmental burdens, including energy use. This chapter highlights some of the innovative irrigation practices and technologies that enhance food production and, at the same time, reduce water use in agriculture. The chapter broadly discusses WUE and water productivity (WP) in irrigated agriculture from engineering and agronomic perspectives. The chapter further highlights some of the environmental impacts of irrigation expansion and the possible solutions. We further provide the importance of accurate spatial information on irrigated areas to inform policy on irrigation expansion. The Water Research Commission (WRC) of South Africa has been spearheading research on the sustainable use of water for the past 50 years as part of its research agenda. In Ting, D. S.-K.; O’Brien, P.

Irrigated agriculture remains the dominant use of freshwater in the United States, although its share of use is declining. Irrigated cropland area has expanded over 40 percent since 1969, while water application rates have declined about 20 percent. The total quantity of irrigation water applied increased about 10 percent since 1969. Nationally, the average variable cost of supplying water for irrigation was about $50 per acre in 2003; however, that amount does not reflect the full value of water. This book presents leading-edge research from around the world on this topic.
