Book Description
This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.

Book Description
The role of irrigation in gearing agriculture development towards a broader economic growth is undeniable. Accordingly, irrigation is growing into key operational strategy for governments and their agencies to increase agricultural productivity, thus combatting food insecurity and boosting overall growth. While agriculture absorbs rural workforce, generates income and increases food security, it has become the most important driver in freshwater exploitation. The rapid expansion of water demand leads to the generalized phenomena of imbalance between water supply and water demand. This increasing pressure on water resources urges enhancing Water Use Efficiency. Enhancing Water Use Efficiency requires actions at all levels, from agricultural practitioners to scheme managers, and up to the policy-makers. The objective of this Field Guide is to show practical measures to improve Water Use Efficiency in small-scale agriculture based on case studies from Burkina Faso, Morocco and Uganda. The Book not only presents applicable Water Use Efficiency measures, but also guide the readers through their real-term implementation. While the Guide provides complete set of instructions to improve Water Use Efficiency in order to reach optimal irrigation practices, the successful outcome still depends on the farmers’ willingness to embrace and adopt the recommended measures. The Guide holds in evidence that farmers are often constrained by available resources to improve their practices in terms of budget, inputs or labour. In order to take these issues into account, the recommendations are limited on practical measures, which can be followed by farmers without requiring additional resources.

Book Description
This policy guide is drawn from the results of the FAO Project “Strengthening Agricultural Water Efficiency and Productivity at the African and Global Level” funded by the Swiss Agency for Development and cooperation (SDC). The long term vision of the project was that the in-country findings and processes which are of common nature can be synthesized and scaled up to other countries in a regional cooperation process and globally. This will eventually lead to the increase of investment in Agricultural Water Management (AWM) in the targeted countries – and beyond – that is socially equitable, profitable at the farm level, economically viable, environmentally neutral or positive, and sustainable. The Guide focuses on the specific component of Enhancing Water Use Efficiency at small scale irrigation as one of the major outputs of the project. While creating and implementing Water Use Efficiency (WUE) measures at field level, existing policy frameworks were mapped and analyzed, and recommendations were defined as scalable policy instruments with the aim to demonstrate case-specific experiences to the collectively agreed goal of using water resources efficiently.

Book Description
Management Strategies for Water Use Efficiency and Micro Irrigated Crops presents new research and technologies for making better use of water resources for agricultural purposes. The chapters focus on better management to improve allocation and irrigation water efficiency and look at performance factors as well. Chapters look at irrigation technology, environmental conditions, and scheduling of water application. One section of the book focuses on water management in the cultivation of sugarcane, a very important industrial crop used in many fields. Other sections are devoted to principles and challenging technologies, water use efficiency for drip-irrigated crops, performance of fertigated rice under micro irrigation, and evaluation of performance of drip-irrigated crops. This valuable book is a must for those struggling to find ways to address the need to maintain efficient crop production in the midst of water shortages. With chapters from hands-on experts in the field, the book will be an invaluable reference and guide to effective micro irrigation methods.

Book Description
This book is in the nature of a primer, providing a basic review and analysis of the principles governing soil-crop-water-climate relationships, irrigation and the efficient utilization of water in arid and semiarid regions. It presents a critique of traditional and of current irrigation concepts and practices, pointing out the needs and potentialities for improving the efficiency of land and water use in developing countries. Starting from a basic analysis of the environmental, physiological and agronomic factors affecting irrigation, the book contrasts historical and modern approaches to management. It then describes methods of scheduling irrigation and of measuring irrigation water, and compares alternative irrigation systems. It also specifies the requirements and methods of drainage and salinity control. Finally, this book discusses some of the human considerations involved in the vital task of developing sound, appropriate and sustainable irrigation systems.

Book Description
An irrigation system is a method used to supply water to crops or landscapes in a controlled manner, typically to assist with crop growth or maintain landscapes. There are various types of irrigation systems, including drip irrigation, sprinkler systems, and flood irrigation, each with its own advantages and applications. The significance of irrigation management cannot be overstated. It plays a pivotal role in agricultural success, environmental protection, and water conservation. By managing irrigation systems effectively, farmers can optimize water usage, reduce expenses, and enhance crop yields. Furthermore, efficient irrigation practices aid in conserving water resources, mitigating soil erosion, and alleviating the impacts of droughts and water scarcity.

Book Description
For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).
