Irrigation is the dominant consumer of fresh water world-wide, accounting for as much as 80% of use in many water-short countries. Two issues dominate the problems in water resources management generally, and especially the management of irrigation systems: scarcity of water to meet competing demands, and scarcity of funds to finance operation, maintenance and renewal of existing facilities. Various international conferences, donor policies and academic papers have pointed to the contribution that appropriate irrigation service charging systems can make to both problems. This book is unique in that it connects policy objectives in water pricing with the practicalities of a setting up an irrigation water charging systems. It discusses the different types of water charging systems as well as the basis for quantifying and calculating the charges in the real world. Based on practical experiences in a range of countries , it also looks at possibilities for cost rationalizations and developing a broad range of revenue streams. The book concludes with a systematic explanation on how to design an irrigation water charging system - looking at assessment, billing and improving collection performance. - E-bokEngelska, 2016

Climate change and declining water resources threaten food production systems worldwide, increasing the need for efficient agricultural processes. The Shanxi Province of the People''s Republic of China has been experiencing declining groundwater tables since 1956. This publication provides examples of how the Asian Development Bank''s development support met the rising challenges in water security, food production, and climate change faced by communities in the Shanxi Province. It describes initiatives in four counties in the Shanxi Province selected as pilot areas, where traditional farmers learned modern methods of groundwater use and management. As a result, options for more sustainable use of groundwater were introduced, while farm labor was reduced, crop yields increased, and water was used more efficiently. - E-bokEngelska, 2026

A case for Re-allocation of Irrigation WaterWater allocation means formal and informal system that determines who is able to use water resources, when, where and how much. The irrigation systems designed in the whole world have become too old with respect to water distribution i.e., water sharing among the stakeholders and the necessary knowledge and tools of calculation in this regard has increased many times than at the time of irrigation system designing. Moreover, groundwater use has become very important in irrigation and depth to groundwater has also variably increased many times, especially in cities which mainly depend on groundwater for their water supply. Also, the groundwater is a by-product of surface water supply including irrigation and rainfall. Therefore, re-allocation of irrigation water is necessary now.This book is particularly for researchers, operators, policy makers, consultants and students. It demonstrates re-allocation application for Bari Doab in Pakistan and it also presents the need for improvement in irrigation water allocations amongst canals in Lower Indus. It demonstrates that Rice Command takes more water than required resulting in waterlogging and emphasis for re-allocation for its solution along with drainage. Overall the book emphasizes on required re-allocation for improved water governance for agriculture and other uses, particularly domestic uses have become necessary to fulfill with passage of time due to urbanization. Presently, in many cases over the world, formal water re-allocation is not a topic of discussion and practices are accepted as they are, with no plans to improve.Moreover shape files of irrigation channels, their command areas, salinity measured in 1981and 2002-04, texture of the soils lying on Pakistani side of IBIS and shape files pertaining to Indian boundary of the IBIS and rectified jpg of canal system in India, along with rivers and boundary of Indus Basin are shared herewith in zipped folders in the form of link at the end of page 3 in chapter 1.
