Book Description
The threats posed by salt-affected soils to global food security are dire. According to the recent Global salt-affected soils map, over 424 million hectares of topsoil (0–30 cm) and 833 million hectares of subsoil (30–100 cm) are currently salt-affected. This practical guide to soil and water management in salt-affected areas provides vital information to farmers dealing with salinity and sodicity issues on their farms and assists them in following suggested practices to mitigate or/and to adapt to these unfavourable conditions without compromising further losses in yields.

Book Description
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.

Book Description
Due to the urgent need to protect communities, ecosystems, and economies from the impacts of a changing climate, adaptation is becoming increasingly relevant. Climate change is already a significant stressor on most global and local value chains and threatens food security. This makes timely implementation of sustainable adaptation actions that catalyse agrifood system resilience indispensable for working towards better nutrition, better environments and better production, leaving no one behind. Recognizing the important role adaptation plays for agrifood systems, and its prominence in the Paris Agreement, the paper presents and reflects on FAO’s repertoire of different adaptation actions and solutions. Complementing the conclusion of the Global Stocktake at COP28, it comprehensively summarizes FAO’s efforts to boost progress in global adaptation actions. The paper (a) emphasizes the importance of bringing agrifood systems into the global adaptation agenda and policy landscape; (b) creates a cross-sectoral portfolio of FAO adaptation solutions covering multiple scales and approaches; (c) gives an insight into FAO's work with partners and Members and presents relevant networks and collaborations. Laying out FAO’s guiding principles according to the FAO Strategy on Climate Change 2022–2031, it underscores FAO’s efforts for transformative action in agrifood systems and demonstrates FAO's people-centered approach to climate change adaptation.

Book Description
The book of proceedings of the joint meeting of the International Network of Salt-Affected Soils (INSAS) and COST Action on the sustainable use of salt-affected lands (SUSTAIN) contains the abstracts of the oral and poster presentations presented during the workshop in Valencia, Spain (27-31 May, 2024). The presentations covered multiple topics related to the management, policy of salt-affected soils as well as crops adapted to these soils. These abstracts describe different approaches that provide insights to managing agriculture in saline conditions and ensuring food security for the world's growing population.

Book Description
How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Book Description
Many fishery biologists and policy makers involved in inland fisheries management and planning are unaware of GIS technology and its potential for fisheries planning and management. The FAO Inland Water Resources and Aquaculture Service (FIRI) has been active for the last 19 years in promoting the use of GIS and remote sensing in fisheries and aquaculture. Promotional activities have been carried out through training, projects, field missions, and oral presentations and publications. However, a manual to use along with GIS software for the fisheries biologists in the field explaining GIS in a way that is understandable to non-GIS users had not been produced until now. This manual was written to overcome this knowledge-gap, it is a "do-it-yourself" manual giving a short introduction to GIS software and its applications in fishery science. The overall objective of this manual is to encourage fishery managers to use this tool (GIS) to foster the sustainable use of natural resources. There are five main sections in the manual: GIS concepts and functions and key tools provided by ArcView 3.x, Geographic coordinate system and map projections, Raster data and analysis, Regression analysis, and Application case studies. All sections are accompanied by exercises that have been designed to illustrate key applications of GIS in inland and marine fisheries management. Also, a custom-designed ArcView grid regression extension is included to show the integration of GIS with surplus production models.
