This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Dryland salinity is becoming a growing problem for Australia, as it impacts upon agriculture, water quality, infrastructure and the environment. In the context of developing a national policy for natural resource management, this report contains the outcomes of the review of the current national policy framework on dryland salinity and outlines new strategic directions. This policy framework recognises that dryland salinity should be addressed in an integrated manner with other land, water and vegetation degradation issues. Rather than in isolation, and at the appropriate catchment and regional scale. While this report can provide a broad approach to addressing dryland salinity, it does not suggest that the dryland salinity problem can be entirely solved or that we have all the knowledge required to develop solutions to the problem. The directions outlined in this document are the result of a fruitful collaboration across jurisdictions, acknowledging that governments and industry must work together in partnership with communities to ensure that the future management of dryland salinity achieves significant positive change.

Abstract: Prepared by the Water Quality and Drainage Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE. Agricultural Salinity Assessment and Management, second edition, considers worldwide salinity and trace element management in irrigated agriculture and water supplies. This updated edition provides a reference to help sustain irrigated agriculture and integrates contemporary concepts and management practices. It covers technical and scientific aspects of agricultural salinity management, as well as environmental, economic, and legal concerns. Topics include: nature and extent of agricultural salinity; diagnosis of salinity problems and selection of control practices; soil response to saline and sodic conditions; plant responses to saline and sodic conditions; long-term regional-scale modeling of soil salinity; case study of San Joaquin Valley, California; institutional and salinity issues on the Upper Rio Grande; and viability of irrigated agriculture with expanding space and time. The second edition of MOP 71 is valuable to water professionals, engineers, scientists, practitioners, and educators interested in developing and managing ever more constrained water supplies worldwide

Human-induced salinisation is a major threat to the world's land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world's population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world's irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.
