Описание:
Improving agricultural water use efficiency (WUE) is vitally important in many parts of the world due to the decreasing availability of water resources and the increasing competition for water between different users. Micro irrigation is an effective tool for conserving water resources. Studies have revealed a significant water savings, ranging from 40% to 70% under drip irrigation compared with surface irrigation. This new volume, Engineering Interventions in Sustainable Trickle Irrigation: Irrigation Requirements and Uniformity, Fertigation, and Crop Performance, presents valuable research that evaluates crop water and fertigation requirements, examines optimum irrigation and fertigation scheduling, and analyzes the performance of agricultural crops under micro irrigation.
With an interdisciplinary perspective, this volume addresses the urgent need to explore and investigates the current shortcomings and challenges of water resources engineering, especially in micro irrigation engineering. The volume discusses crop water requirements, fertigation technology, and performance of agricultural crops under best management practices. The chapter authors present research studies on drip irrigated tomato, chilies, cucumber, eggplant, cabbage, garlic, sugarcane maize, cashew nut, sapota, banana, mango, and blueberries.
Removing the research gap, this volume provides new information that will be valuable to those involved in micro irrigation engineering.

Описание:
Closed circuit trickle irrigation is a form of micro irrigation that increases energy and water efficiency by using closed circuit drip irrigation systems designs. Modifications are made to traditional micro irrigation methods to reduce some of the problems and constraints, such as low compressor water at the end of irrigation lines. This approach has proved successful for the irrigation of fruit trees and some vegetable and field crops. Closed circuits of drip irrigation systems require about half of the water needed by sprinkler or surface irrigation. Lower operating pressures and flow rates result in reduced energy costs, and a higher degree of water control is attainable as well. Plants can be supplied with more precise amounts of water, and disease and insect damage is reduced because plant foliage stays dry. Fertilizers can also be applied through this type of system, which can result in a reduction of fertilizer and fertilizer costs.
This new volume in the Research Advances in Sustainable Micro Irrigation book series presents a diverse collection of research on closed circuit irrigational technology and design and provides studies of its use on such crops as wheat, maize, yellow corn, soybeans, rice, and snap peas.
The book explores:
- Soil moisture and salinity distributions under modified sprinkler irrigation
- Performance of sprinkler irrigation
- Design considerations for closed circuit drip irrigation systems
- Performance of bubbler irrigation
- Energy and water savings of drip irrigation systems
- Automation of mini-sprinkler and drip irrigation systems
- Water and fertilizer use efficiencies for drip irrigated maize
- Evaluation of emitter clogging for drip irrigated systems
This book will be valuable for those interested in irrigation planning and management, namely, researchers, scientists, educators, upper-level students, agricultural extension services, and others.

Описание: Human activity is changing the global environment at an unprecedented rate while humanity faces a range of complex and interrelated challenges to local, regional and global development, human security and politics. Food security ranks high on the science, policy and development agendas. However, most research linking global change and food systems examines the impact of climate change on agricultural production, or the impact of agriculture on land use, pollution and biodiversity, overlooking interactions with other aspects of the food system – such as food processing, packaging, transportation and consumption and employment derived from these activities. This book demonstrates that new threats to food security which arise from environmental change require more than simply a focus on agricultural practices – what is needed is an integrated food system approach. The authors point out that the process of adapting food systems to global environmental change is not simply a search for technological solutions to increase agricultural yields. Tradeoffs across multiple scales among food system outcomes are a prevalent feature of globalized food systems. Within food systems, there are key underexplored areas that are both sensitive to environmental change and crucial to understanding its implications for food security and adaptation strategies. The authors assert that technical prescriptions alone will not efficiently manage the food security challenge. This book is their contribution to a new paradigm, which addresses food systems holistically by engaging researchers in multiple disciplines to understand the causes and drivers of vulnerability.

Описание: In this volume water harvesting is presented as a set of approaches which occupy the intermediate position on the water-management spectrum. It provides lessons to promote sustainable development in Sub-Sarahan Africa, where water is an irregular yet necessary commodity, and its availability a major constraint on agriculture.
