Book Description
With the strong competition that is arising for water resources the modernisation of irrigation systems is becoming a critical issue. One of the alternatives to modernisation is the use of pressurised systems to replace part of the existing networks. This publication analyses the performance of pressurised irrigation systems operating on demand, and provides revised criteria for the design of such irrigation networks. For this purpose, new approaches and a computer program have been developed. The program has been tested in several field situations in the Mediterranean Basin and has demonstrated its usefulness not only by quickly identifying weak points in irrigation networks but also by identifying the power requirements of pumping stations needed to satisfy varying demand situations.

Book Description
FAO's Irrigation and Drainage Paper No. [Author] 63 introduced the MASSCOTE methodology in 2007, tailored for modernizing large-scale canal irrigation systems. [Author] With global interest shifting towards pressurized pipe systems, particularly in water-scarce regions, the need for a similar methodology became apparent. [Author] Pressurized systems offer advantages like on-demand irrigation, reduced water wastage, and environmental impact. [Author] However, they require complex management due to changing water demands. [Author] To address this, FAO developed the MASSPRES approach, building on MASSCOTE's principles. [Author] MASSPRES aims to assess and enhance the performance of pressurized irrigation schemes, introducing steps like the Rapid Appraisal Procedure (RAP) for system mapping. [Author] It offers innovative methods for evaluating pressures and discharges at farm hydrants under various operating conditions, replacing earlier statistical analysis approaches. [Author] MASSPRES incorporates indicators for capacity, reliability, distribution equity, sensitivity to change, and perturbation risks into user-friendly software. [Author] Practical examples from Egypt, Italy, Spain, and Tunisia showcase its effectiveness. [Author] As governments seek to improve water and food production amidst increasing water scarcity, adopting technologies like pressurized irrigation becomes crucial. [Author] MASSPRES provides a systematic framework for both upgrading existing systems and designing future ones, addressing the complexities of managing pressurized irrigation efficiently. [Author]

Book Description
The book Irrigation Systems and Practices in Challenging Environments is divided into two interesting sections, with the first section titled Agricultural Water Productivity in Stressed Environments, which consists of nine chapters technically crafted by experts in their own right in their fields of expertise. Topics range from effects of irrigation on the physiology of plants, deficit irrigation practices and the genetic manipulation, to creating drought tolerant variety and a host of interesting topics to cater for the those interested in the plant water soil atmosphere relationships and agronomic practices relevant in many challenging environments, more so with the onslaught of global warming, climate change and the accompanying agro-meteorological impacts. The second section, with eight chapters, deals with systems of irrigation practices around the world, covering different climate zones apart from showing casing practices for sustainable irrigation practices and more efficient ways of conveying irrigation waters - the life blood of agriculture, undoubtedly the most important sector in the world.

Book Description
In a worldwide context of ever-growing competition for water and land, climate change, droughts and man-made water scarcity, and less-participatory water governance, agriculture faces the great challenge of producing enough food for a continually increasing population. In this line, this book provides a broad overview of innovation issues in the complex water–agriculture–food nexus, thus also relative to their interconnections and dependences. Issues refer to different spatial scales, from the field or the farm to the irrigation system or the river basin. Multidisciplinary approaches are used when analyzing the relationships between water, agriculture, and food security. The covered issues are quite diverse and include: innovation in crop evapotranspiration, crop coefficients and modeling; updates in research relative to crop water use and saving; irrigation scheduling and systems design; simulation models to support water and agricultural decisions; issues to cope with water scarcity and climate change; advances in water resource quality and sustainable uses; new tools for mapping and use of remote sensing information; and fostering a participative and inclusive governance of water for food security and population welfare. This book brings together a variety of contributions by leading international experts, professionals, and scholars in those diverse fields. It represents a major synthesis and state-of-the-art on various subjects, thus providing a valuable and updated resource for all researchers, professionals, policymakers, and post-graduate students interested in the complex world of the water–agriculture–food nexus.

Book Description
Irrigation is becoming an activity of precision, where combining information collected from various sources is necessary to optimally manage resources. New management strategies, such as big data techniques, sensors, artificial intelligence, unmanned aerial vehicles (UAV), and new technologies in general, are becoming more relevant every day. As such, modeling techniques, both at the water distribution network and the farm levels, will be essential to gather information from various sources and offer useful recommendations for decision-making processes. In this book, 10 high quality papers were selected that cover a wide range of issues that are relevant to the different aspects related to irrigation management: water source and distribution network, plot irrigation systems, and crop water management.

Book Description
The agricultural industry is dealing with enormous challenges across the globe, including the limited availability of arable lands and fresh water, as well as the effect of climate change. Machinery plays a crucial role in agriculture and farming systems, in order to feed the world’s growing population. In the last decade, we have witnessed major advances in agricultural machinery and technologies, particularly as manufacturers and researchers develop and apply various novel ways of automation as well as the data and information gathering and analyzing capabilities of their machinery. This book presents the state-of-the-art information on the important innovations in the agricultural and horticultural industry. It reviews and presents different novel technologies and implementation of these technologies to optimize farming processes and food production. There are four sections, each addressing a specific area of development. Section I discusses the recent development of farm machinery and technology. Section II focuses on water and irrigation engineering. Section III covers harvesting and post-harvest technology. Section IV describes computer modelling and simulation. Each section highlights current industry trends and latest research progress. This book is ideal for those working in or are associated with the fields of agriculture, agri-food chain and technology development and promotion.

Book Description
In recent decades, the intensification of unpredictable events including the Covid-19 outbreak, Brexit, trade warfare, religion-inspired terrorism and civil wars, and climate change has resulted in serious loss of human lives and property, a decrease in biodiversity and natural hazards (with long-term negative impacts on environment), and impeded social and economic development. Economics and Engineering of Unpredictable Events: Modelling, Planning and Policies provides an integrated view of the management of unpredictable events incorporating three major perspectives: economic management, environmental planning and engineering models. Contributors from economics, planning, regional science, and engineering address key questions including; How resilient are human societies and their habitats? What should societies do to shift from being vulnerable to being more resilient? And what role should planning and policies play to protect communities and the natural environment? The chapters cover academic debates, conceptual reflections, case studies, methods, and strategy development with particular reference to mitigation and adaptation in face of unpredictable events. This book is of particular interest to readers of economic policy, urban and regional planning and engineering.
