Water is the most limiting factor for irrigated agriculture in arid and semi-arid areas of European Mediterranean countries. In this book, the authors' explore the different mechanisms and robust tools to monitor plant-water status, with the aim of keeping crops within a certain threshold of moderate-to-mild water stress. Other chapters include research on agricultural techniques in semi-arid environments that would benefit the surrounding environment and impact soil management. The third chapter includes site-specific documentation of landforms developed in the Ejina Basin in Central Asia and its implications for late quaternary landscape evolution and palaeoenvironmental change. The fourth chapter focuses on the links between economic value addition, demographics, personal income and entrepreneurship in selected South African towns. The last chapter reviews thirty years of ecological monitoring in Algerian arid rangelands.

Today's irrigation management faces challenges and competition with other sectors (ie: household, industry, and environmental), quality degradation, and uncertain climatic conditions. To cope with these situations, the irrigation managers need precise estimation/determination of irrigation needs for crops, advance/water-saving techniques for water application, water conservation approaches, economic considerations in irrigation, and potentials for using marginal quality water in irrigation (such as saline water, and waste-water). This book focuses on all of the above issues: starting with irrigation management strategies for field crops -- to suitability of saline and waste-water as irrigation water. The book is useful to identify the need and adopt emerging technologies for irrigation management, as well as to identify appropriate methodologies for social, economic, and environmental benefits of improved irrigation management.

Agricultural water management includes many topics: farm-level and regional water management, irrigation, drainage, and salinity management of cultivated areas, collection and storage of rainfall in relation to soil properties and vegetation; the role of groundwater and surface water in nutrient cycling, exploitation and protection of water resources, control of flooding, erosion, and desertification. This book presents leading-edge research from around the world.

Today, John Deere is remembered-some say mistakenly-as the inventor of the steel plow. Who was this legendary man and how did he create the internationally renowned company that still bears his name? He began as a debt-stricken blacksmith who, fleeing debt in New England in the 1830s, set up shop in a little town on the Illinois frontier. There, in response to farmers' struggles, he designed a new plow that cut through the impervious prairie sod and lay open the rich, heavy soil for planting. The demand for his polished steel plow convinced him to specialize in farm implements. In the decades before the Civil War, John Deere envisioned a company supplying midwestern farmers with reliable, affordable equipment. He used only high quality, imported steel and resisted pressure to raise prices. At the same time, he won respectful affection from his employees by working alongside them on the shop floor. Upon taking the helm in the 1860s, John's only surviving son, Charles, expanded the Moline factories to increase production, started branch houses in major midwestern cities to speed distribution, and began to transform the company into a modern corporation. The transformation didn't come without difficulties however: Charles found himself battling the Grange, facing threats of labor unions and strikes led by his own employees, and enduring patent suits and blatant thefts of product designs and advertising.

Egyptian agriculture is uniquely dependent on water, with over 95 per cent of agricultural production originating from land irrigated by the Nile. The improvement of irrigation systems and better control over water by farmers is therefore crucial to the drive to raise productivity in the current ocntext of scarce water resources, rich but underutilized land and changes in the institutional environment of the economy after "liberalization." This text evaluates the ambitious state-of-the-art Irrigation Improvement Project (IIP) and should be of interest to all those concerned with issues of water and development in the Middle East.

A Gottingen thesis studying Iron Age sickles and scythes and other reaping equipment from Northern Europe and Scandinavia. Catalogue includes 405 examples. To determine the precise function of various tools the author made replicas and tried them out. Discussion shows how changing tool types reflect changing farming patterns. 246S 583, 1993)

With a roster of international contributors, this volume offers an abundance of solutions to address agricultural water management challenges in today's water-scarce areas of the world. The authors present studies on farmer-friendly irrigation scheduling methods, model-based analysis of crop water requirements, ways to optimize surface irrigation systems, and hydraulic design and management of surface water systems. The book goes on to highlight ways to improve soil properties by taking into account spatial, temporal, and spectral variability in soil properties. The volume also covers various innovative research studies on soil and water productivity of vegetable cultivation under water-stressed areas, application of coir geotextiles, and the role of biofertilizers in controlling soil degradation and maintaining fertile topsoil. Crop management strategies to enhance the efficient use of marginal and saline lands for nonconventional crops are also discussed. The book is divided into four sections, covering: engineering interventions in irrigation management technological interventions in management of soil properties technological inventions for soil and water conservation crop management for non-conventional use This volume will serve as an invaluable resource for academicians, researchers, engineers, agronomists, extension officers, students, and farmers in the broad discipline of agricultural and biological engineering.

Micro Irrigation Management: Technological Advances and Their Applications, the fifth book in the Innovations and Challenges in Micro Irrigation book series, is a valuable reference volume on micro irrigation and water management for professional training institutes, technical agricultural centers, irrigation centers, agricultural extension service, and other agencies who work with micro irrigation programs. With an international focus, this new book focuses on applications of solar energy in micro irrigation and other important technological advances. It includes case studies and illustrative examples on drip irrigation design.

In most developing countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in large scale water pollution and the use of very poor quality water for crop irrigation especially in the vicinity of urban centres. This can create significant risks to public health, particularly where crops are eaten raw. Wastewater Irrigation and Health approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings. The book therefore complements other books on the topic of wastewater which focus on high-end treatment options and the use of treated wastewater. This book moves the debate forward by covering also the common reality of untreated wastewater, greywater and excreta use. It presents the state-of-the-art on quantitative risk assessment and low-cost options for health risk reduction, from treatment to on-farm and off-farm measures, in support of the multiple barrier approach of the 2006 guidelines for safe wastewater irrigation published by the World Health Organization. The 38 authors and co-authors are international key experts in the field of wastewater irrigation representing a mix of agronomists, engineers, social scientists and public health experts from Africa, Asia, Europe, North America and Australia. The chapters highlight experiences across the developing world with reference to various case studies from sub-Saharan Africa, Asia, Mexico and the Middle East. The book also addresses options for resource recovery and wastewater governance, thus clearly establishes a connection between agriculture, health and sanitation, which is often the missing link in the current discussion on 'making wastewater an asset'.
