ArticleIntegrated soil-water-crop management in salt-affected areas 2023
Also available in:
No results found.Salt-affected soils, which includes both saline and sodic soils, are found in various regions around the world, on all continents and are present under a wide range of climatic conditions. Soil salinization and sodification are significant processes of degradation that pose a serious threat to soils and their ecosystem services. They negatively impact plant growth, limit crop productivity and are considered major challenges for agricultural production, food security, and sustainability in these areas. Efforts are being made worldwide to address the issues related to salt-affected soils including the implementation of improved irrigation practices to minimize salt accumulation. Overall, the management of salt-affected soils is crucial for ensuring the long-term sustainability of agricultural systems and the protection of ecosystems in arid and semi-arid regions. -
Book (stand-alone)Global status of salt-affected soils
Main report
2024Also available in:
No results found.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. -
Book (stand-alone)Salt-affected soils: threats and potentials
Proceedings of the joint meeeting of INSAS and SUSTAIN – Valencia, Spain | May 27–31, 2024
2024Also available in:
No results found.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.
