Salt-affected soils such as saline or sodic soils are distributed in all continents at various levels of problem intensity. They are soils with high amounts of soluble salts and/or sodium ions. An updated information of their distribution and drivers is a first step towards their sustainable management. This book provides technical guidelines and approach for developing a harmonized multiscale soil information of salt-affected soils. The book is organized into three sections covering seven chapters. The sections are sequentially arranged but independently designed to benefit focused readership who may want to go straight to any section. Section 1 gives the background information. It has three chapters covering existing literature on the characteristics and mapping methods for salt problems in the soil. It is intended to illustrate the basic concepts, linkage of the characteristics of salt-affected soils with input data requirements for their mapping, existing classification methods, and global distribution of these soils. Section 2 covers the methodological procedures for developing multiscale spatial information of salt-affected soils. It has two chapters describing requirements, input data preparation, and the procedural steps for developing spatial information of salt-affected soils. It outlines how data from different sources and characteristics are harmonized and integrated to produce information of salt-affected soils. Section 3 covers information sharing and resources mobilization when developing information on salt-affected soils. It gives the guidelines for preparing spatial maps and steps for value-addition to benefit end-users of the information. It also contains a generic training program for building technical capacity for mapping salt-affected

Salt-affected soils, characterized by high soluble salts (saline) or exchangeable sodium (sodic), impact plant growth and occur globally, especially in arid and coastal regions. Salinization stems from natural causes (e.g. climate change, sea level rise) and human actions (e.g. poor irrigation practices, excessive water use). FAO’s Global Map of Salt-Affected Soils reveals that over 1 381 million hectares, 10.7 percent of global land, are affected, with Australia, Argentina and Kazakhstan among the most impacted countries. Increasing aridity and water demand amplify soil degradation risks, particularly in developing regions.Climate change and water scarcity threaten agricultural productivity, with substantial crop yield losses observed in saline areas. Halophytes and salt-tolerant crops provide a foundation for saline agriculture, yet many salt-affected soils remain unprotected and inadequately regulated. FAO’s INSAS (International Network of Salt-Affected Soils) underscores the need for updated data, harmonized salinity measurements, and sustainable management practices, with enhanced training and policy frameworks.Mitigation strategies like improved drainage, soil amendments, and the cultivation of salt-tolerant plants are recommended. Key recommendations include scaling sustainable practices, investing in salt-tolerant crop markets, improving data collection and water quality monitoring, conserving ecosystems, and fostering cross-sector collaboration. Such integrated efforts aim to boost food production and resilience in affected regions while protecting vital ecosystems.

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.

This book presents recent research work on Biosaline Agriculture presented during First International Forum on Biosaline Agriculture in Laayoune, Morocco from May 3rd to May 4th 2019. The aim of this book is to showcase the global potential of Biosaline agriculture, provide an update on the development of recent innovations in the field of Biosaline agriculture, the best management practices to safely use brackish and saline water, highlight the use of non-conventional water in marginal environment production and the current advanced technologies of desalination of brackish and seawater. The different chapters will also discuss solutions that are adapted to local conditions as part of a sustainable development perspective. The book provides up-to-date technical and scientific data on growing crops under marginal environment so as to encourage the dissemination of this knowledge in the best practices to increase the productivity in Biosaline agriculture, in view of the potential to contribute to food security. The book is expected to stimulate interest in the non-conventional water resources and crops among junior and senior researchers and among those who are increasingly focused on exploiting marginal environments. It will also be of interest to decision-makers and the public and private sectors to jointly address the issues of food security especially of the poor and vulnerable people living in marginal environments worldwide by providing innovative technology transfer.

This document was generated under the Technical Cooperation Project TCP/RAB/3802 “Capacity development for the sustainable management of soil resources in the NENA region to achieve the Sustainable Development Goals (SDGs)” and it was formulated to address the regional and national prerequisites to raise awareness on the importance of soils in the NENA region and to conserve and manage them sustainably. Soil degradation by salinity, sodicity and erosion and the resulting loss in soil functions represent a growing threat in NENA that increasingly threatens food security in the region. The two-year TCP/RAB/3802 project started in October 2020. The project ultimately involved 11 countries in NENA, (Hashemite Kingdom of Jordan, Islamic Republic of Iran, Kingdom of Morocco, the Lebanese Republic, Republic of Iraq, Republic of Sudan, Republic of Tunisia, Republic of Yemen, Palestine, Sultanate of Oman and Syrian Arab Republic) and focused on (1) enhancing the understanding of soil characteristics/challenges and management practices, (2) strengthening national capacities for the implementation of normative tools on sustainable soil management (SSM), and (3) strengthening regional and interregional collaboration on SSM.
