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.

This book presents systematic scientific appraisal, classification, genesis and viable technologies for reclamation and management of salt-affected soils and marginal quality waters across India and several other countries. Nature, solubility and geo-chemical mobility of salts have been provided as basis for the development of alkali and saline soils and groundwaters under specific agro-hydro-ecological regions. Chemical amendment (gypsum) based reclamation technology of alkali soils and related pre and post-reclamation water, nutrient and crop management interventions, including re-sodification issues have been comprehensively addressed. Features and operational guidelines of surface, subsurface, vertical and bio-drainage systems have been thoroughly discussed; likewise, amelioration of irrigation induced saline soils in inland and coastal regions and preventive measures for control of salinity and waterlogging along with environmental trade-offs. Practical approaches for amelioration and judicious use of saline, alkali, high SAR- saline and waste waters have been synthesized for different cropping and agro- forestry systems. Emerging issues on use of industrial by-products as amendments for alkali soils, physiological aspects of salt resistance, anatomical and biochemical mechanism of submergence tolerance, specific ion effects of poor quality waters, crop diversification, groundwater recharge, rejuvenation of tsunami affected coastal soils, safety against occurrence of poisonous gas in tube well pits, paddy straw burning and others have been adequately deliberated upon. Combining scientific principles with field experiences, the book is expected to serve as a useful knowledge base for research workers, teachers and students of soil science, agronomy, plant breeding, forestry, irrigation engineering, extension workers, environmentalists and planners associated with reclamation and management of salt affected soils and waters on sustainable basis in developing and developed countries.

The GSAS21 was held virtually on the Zoom platform on 20-22 October 2021 and was attended by over 4 000 participants. The objective of the symposium was to combine science, policy, and practice to evaluate the issues related to salt-affected soils and to formulate a strategy for the implementation of Voluntary Guidelines for Sustainable Soil Management in the areas affected by salinity and sodicity. The GSAS21 symposium was structured around three main themes focusing on: 1) Assessment, mapping, and monitoring of salt-affected soils; 2) Integrated soil – water – crop solutions in rehabilitation and management of salt-affected areas; 3) Agenda for action to prevent and rehabilitate salt-affected soils, protect natural saline and sodic soils, and scale-up sustainable soil management practices. The fourth session on testimonies from the field was organized to showcase the good practices illustrating the rehabilitation and sustainable use of salt-affected soils. The symposium included more than 70 oral presentations, presented over 17 hours of parallel sessions. Recordings of the presentations can be accessed via . In addition, 58 posters were open for public voting during the GSAS. Over 67 000 votes have been received which helped identify three winners of the poster session. The posters are available from . The recommendations presented in this document aim to support decision-making and innovative actions to minimize the challenges posed by soil salinity and sodicity, thereby assisting in the augmentation of global food security and ecosystem protection through salt-affected soils management in impacted regions.

In biology, the very big global and thevery small molecular issues currently appear to be in the limelight ofpublic interest and research funding policies. They are in danger of drifting apart from each other. They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due to progressing salinization of arable land is of vital interest for society. Explanations and basic understanding as well as solutions and remedies may finally lie at the molecular level. It is a general approach in science to look for understanding of any system under study at the next finer (or "lower") level of scaling. This in itself shows that we need a whole ladder of levels with increasingly finer steps from the global impact to the molecular bases of SALINITY relations. It is in this vein that the 22 chapters of this book aim at providing an integrated view of SALINITY.
