Book Synopsis Drip Irrigation for Agriculture by : Jean-Philippe Venot
Download or read book Drip Irrigation for Agriculture written by Jean-Philippe Venot and published by Routledge. This book was released on 2017-07-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving the efficiency of water use in agriculture is increasingly essential to maintain the profitability and sustainability of farms. This involves applying only the minimum necessary irrigation water to maintain or improve the yield of individual plants. Improving cotton yield involves management of flower/fruit production in relation to vegetative growth. The cotton industry represents a signicant proportion of agricultural production and water use in Australia. Irrigation control strategies can be used to improve site-specific irrigation. These control strategies generally require weather, plant and/or soil data to determine irrigation volumes and/or timing that improve crop water use efficiency while maintaining or improving crop yield. In this dissertation the difficulties in applying standard control theory to irrigation control are reviewed, in particular that the system, the growing crop, varies with time and does not have fully-defined dynamics. Hence, as the plant response and environmental conditions fluctuate throughout the season, control strategies which accommodate temporal and spatial variability in the field and which locally modify the control actions (irrigation amounts) need to be `adaptive'. Such irrigation control systems may then be implemented on large mobile irrigation machines, both `lateral move' and `centre pivot' configurations, to provide automatic machine operation. This dissertation presents the specification and creation of a simulation framework `VARIwise' to aid the development, evaluation and management of spatially and temporally varied site-specific irrigation control strategies. The cotton model OZCOT has been integrated into VARIwise to provide feedback data in the control strategy simulations. VARIwise can accommodate sub-field scale variations in all input parameters using a 1 m2 cell size, and permits application of differing control strategies within the field, as well as differing irrigation amounts down to this scale. An automatic model calibration procedure was developed for VARIwise to enable realtime input of field data into the framework. The model calibration procedure was accurately implemented with measured field data and the calibrated model was then used to evaluate the effect of using different types of data in an irrigation control system. With the field data collected, the model was most effectively calibrated using the full set of plant, soil and weather data, while either weather-and-plant or soil-and-plant input provided adequate inputs to the control system if only two inputs were available. A literature review of control systems identified three adaptive control strategies that are applicable to irrigation, namely: (i) Iterative Learning Control (ILC) which involves applying irrigation volumes to cells in the field calculated by comparing the desired and measured value of the input variable for control (e.g. soil moisture deficit); (ii) iterative hill climbing control which involves applying test irrigation volumes to test cells in the field to determine the application that produced the best crop response and applying that volume to the remainder of the field; and (iii) Model Predictive Control (MPC) which involves using a calibrated crop model to evaluate various irrigation applications and timings to determine which irrigation decision to implement. The three control strategies were implemented and simulated in VARIwise to evaluate their respective robustness to limitations in data availability and system constraints. These strategies effectively adapted to temporal changes in weather conditions and spatially variable soil properties. For the set of field conditions simulated in VARIwise, the ILC, iterative hill climbing and MPC controllers produced their highest yield and water use efficiency with soil data, weather-and-plant data, and the full data input, respectively. MPC was most sensitive to spatially sparse input data but performed well with spatially variable rainfall and limited machine capacity. ILC was least sensitive to spatially sparse input data and variable rainfall, whilst iterative hill climbing control was most sensitive to spatially sparse input data and variable rainfall. Hence, in situations of high data input MPC should be implemented, whilst in situations of low data input ILC should be implemented. Iterative hill climbing control was most sensitive to limited irrigation machine capacity. It is further concluded that cotton yield and irrigation water use efficiency may be significantly improved using adaptive control systems; and that adaptive control systems can adjust the irrigation application and improve the irrigation performance despite various data availability limitations and irrigation hardware constraints.

Available in PDF, EPUB and Kindle. Book excerpt: Many countries around the world are struggling with the challenges of water scarcity, including water for crops. Micro irrigation methods are an effective means to make the most efficient use of available water. This volume, Micro Irrigation Scheduling and Practices, continues the efforts of the book series Innovations and Challenges in Micro Irrigation to provide informative and comprehensive knowledge on micro irrigation methods and practices. This new book presents some of the latest information and research on micro irrigation and covers the area of performance, practices, and design, focusing particularly on the performance of vegetable, fruit and row crops in conjunction with different scheduling and practices. Irrigation scheduling is an important water management strategy, and this book addresses scheduling methods and issues. Design aspects of micro irrigation systems have also been discussed in the book. The authors present their research and studies on scheduling practices and design micro irrigation systems with a variety of fruits and vegetables, including peppers, chili, watermelon, oranges, banana, litchi, rice, sugarcane, sorghum, and marigolds. Micro Irrigation Scheduling and Practices will serve as a valuable reference for researchers, water resources professionals, agricultural extension agencies, farmers, and faculty and students.
