Book Description
One irrigation subsector goal of the Asian Development Bank is to produce more food with less water. Estimates suggest that food production in the developing world must double by. By that year, urban and industrial water demand will have increased from 20% of total regional demand to 40% (about 80% of that water demand is for irrigation). This publication helps define core support areas in the irrigation subsector and set the course for country partnership strategy investments in irrigation for lending and nonlending assistance. See how this guidance note can assist and strengthen the preparation of projects that increase food productivity and security, use water within the resource availability limits, and produce long-term benefits.

Book Description
Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p productivity in rice-based systems.

Book Description
Modernizing irrigation systems in Central Asia could increase the productivity of the irrigation sector to meet growing food and export demand, while also improving farmers’ livelihoods. It could ensure greater irrigation efficiency and crop productivity amid growing water scarcity in the region and deliver cost-effective and reliable irrigation services to farmers. In addition, modernized systems could contribute to national development objectives such as climate resilient economic growth, food security and poverty reduction. This publication, geared to policy-makers, sector managers and technical experts, draws on the findings of a study carried out by an FAO team through the World Bank’s regional assistance programme “Exposure and Practical In-Roads to Modernizing Irrigation in Central Asia”. It is part of the Directions in Investment series under the FAO Investment Centre's Knowledge for Investment (K4I) programme.

Book Description
This document on consumption-based water management (CBWM) distils and expands on the findings of an expert consultation hosted by FAO and the China Institute of Water Resources and Hydropower Research (IWHR). The meeting brought together Chinese and international experts to discuss the technical, governance and broader dimensions of managing consumptive water use, and to understand the implications of more than ten years’ pilot experience in China and its potential for application in a broader range of climatic, political administrative and socioeconomic contexts. The document provides contextual information on CBWM, introduces technical basis for CBWM, takes a closer look at law, policy, and governance and their the relevance in implementing CBWM, and step-by-step detail on implementation of CBWM. Finally, the document argues that the implementation of CBWM requires preliminary steps in developing water accounts, water rights, water allocation processes and associated institutional arrangements, all of which are very relevant and immediately necessary in most countries in Asia.

Book Description
Make the best use of available water for your crops! Water Use in Crop Production explores innovative methods that determine how much water certain crops need, in certain climates, in order to ensure adequate plant growth and help eliminate water waste. Through this informative book, agronomists, growers, researchers, and graduate students will find methods and techniques for effective water management that will save money and conserve water. Water Use in Crop Production will enable you enhance crop quality and quantity and save one of the earth's most important resource. Comprehensive and thorough, this essential book combines two vital needs, food and water, and examines what must be done in order to keep up with the ever-growing human population. Explaining conservation techniques used in Argentina, Australia, Israel, Morocco, New Zealand, the Philippines, Spain, and the United States, Water Use in Crop Production will help you achieve this goal as it discusses water management measures including: avoiding excessive deep percolation reducing runoff lessening water evaporation through methods such as reducing the capillary water flow to the surface of the soil determining the rates at which water is demanded and can be supplied in a specific area to create a plan for limiting water loss studying the root structure of plants to calculate how much water they need using deficit irrigation to help plants save water for future use evaluating citrus water use through the Penman-Monteith model Containing charts, tables, and examples of the concepts it discusses, this book is the culmination of the latest studies on water storage. Water Use in Crop Production provides you with reliable strategies and methods that will help you lessen water expenditures and improve the vitality of crops anywhere in the world.
