Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.

The use of urban wastewater in agriculture is receiving renewed attention, with the increasing scarcity of fresh water resources in many arid and semi-arid regions of the world. Wastewater is a low-cost alternative to conventional irrigation water, although it may carry health and environmental risks. This book critically reviews experience worldwide of these issues. Emphasis is placed on untreated wastewater use by means of field-based case studies from Asia, Africa, the Middle East and Latin America. It brings together a range of perspectives including economic, health, agronomic, environmental, institutional, and policy dimensions.

Irrigation came to the arid West in a wave of optimism about the power of water to make the desert bloom. Mark Fiege’s fascinating and innovative study of irrigation in southern Idaho’s Snake River valley describes a complex interplay of human and natural systems. Using vast quantities of labor, irrigators built dams, excavated canals, laid out farms, and brought millions of acres into cultivation. But at each step, nature rebounded and compromised the intended agricultural order. The result was a new and richly textured landscape made of layer upon layer of technology and intractable natural forces—one that engineers and farmers did not control with the precision they had anticipated. Irrigated Eden vividly portrays how human actions inadvertently helped to create a strange and sometimes baffling ecology.

Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

A practical, bipartisan call to action from the world’s leading thinkers on the environment and sustainability Sustainability has emerged as a global priority over the past several years. The 2015 Paris Agreement on climate change and the adoption of the seventeen Sustainable Development Goals through the United Nations have highlighted the need to address critical challenges such as the buildup of greenhouse gases in the atmosphere, water shortages, and air pollution. But in the United States, partisan divides, regional disputes, and deep disagreements over core principles have made it nearly impossible to chart a course toward a sustainable future. This timely new book, edited by celebrated scholar Daniel C. Esty, offers fresh thinking and forward-looking solutions from environmental thought leaders across the political spectrum. The book’s forty essays cover such subjects as ecology, environmental justice, Big Data, public health, and climate change, all with an emphasis on sustainability. The book focuses on moving toward sustainability through actionable, bipartisan approaches based on rigorous analytical research.

This book targets the issue of water scarcity in Egypt as a typical example of the world water crisis. Today, the available water resource is facing its limit because of rapid increase in water demand as a result of population growth and changes in peoples’ life-style. The basic idea to solve the problem of water scarcity is that the irrigation sector, the biggest user of water, should increase water use efficiency. However, the real problem is how this can be achieved in view of the crucial need for water in this sector. This book addresses this challenge through case studies from the Nile delta in Egypt. The water problem in the Nile delta, the major source for water in Egypt, is discussed in this book from all its various aspects. This book covers the situation before and after the advent of the Aswan High Dam, so that the reader understands the entire development. Another special feature are the extensive and scientific descriptions of contemporary topics in water and agriculture, especially from the viewpoint of water saving and sustainability. These descriptions are based on field experiments and surveys in a six-year international research project. Topics of this book are local, but their implications are global.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

This book deals with past legacies and emerging challenges associated with agriculture production, water and environmental management, and local and national development. It offers a critical interpretation of the tensions associated with the failures of mainstream regulatory regimes and the impacts of global agri-food chains. The various chapters include conceptual and empirical material from research carried out in Brazil, India and Europe. The assessment takes into account the dilemmas faced by farmers, companies, policy-makers and the international community related to growing food demand, water scarcity and environmental degradation. The book also questions most government reactions to those problems that tend to reproduce old, productivist approaches and are normally under the powerful influence of global corporations, mega-supermarkets and investment funds. Its overall message is that the trajectory of agriculture, rural development and environmental management are integral elements of the broader search for justice and novel socio-ecological thinking.
