ArticleJournal 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. -

Managing salt-affected soils for a sustainable future
2023Also available in:
No results found.The proceedings of the second meeting of the International Network of Salt-Affected Soils (INSAS) contain the abstracts of the papers presented during the workshop in Tashkent (22–26 May, 2023). The papers provide the up-to-date scientific knowledge and practical solutions for four topics: (1) mapping, assessing and monitoring of salt-affected soils; (2) sustainable management of salt-affected soils: practices and policy; (3) halophyte and saline agriculture and its effect on soil health; (4) integrated soil and water management under saline/sodic conditions.Under the first topic, modern techniques (geophysics, remote sensing, NIR spectroscopy) for mapping and monitroing of salt-affected soils as wel as mapping of environmental susceptibility to soil salinization in dry regions were presented. Under the second topic, different approaches to reclaim saline and sodic soils and improve seed germination including the use of different organic and inorganic amendments, organic biostimulants, biochar and phytoremediation were discussed. Moreover, biodiversity of salt-affected soils and its change along salinity gradient as well as the impact of soil enzymes on the structure and function of soil microbial communities and how soil degradation is associated with specific soil microbiota were reported. Policy gaps on addressing soil salinity were analyzed and further steps how to integrate agenda on SAS into existing agricultural policies were proposed. The results of Participatory Rural Appraisal approach to survey among farmers were provided. Under the third topic, the results on testing different conventional and non-conventional crops in field trials on salt-affected soils irrigated by fresh and saline water were reported. The influence of soil properties on growing halophytes was considered. Under the fourth topic, the ways to optimize the use of poor-quality irrigation water in agriculture were discussed. Some studies reported about the results of modeling of salt and water transport in soils for estimation of leaching requirement or root zone soil salinity. Several studies reported about the negative aspects of using brackish water leading to secondary soil salinization and sodification. For salt-affected areas with groundwater use for irrigation, the approach combining the Food Systems Approach and integrated water resources management was proposed to address the interdependent challenges of food and water security. -
Book (stand-alone)Technical studyImpact of shrimp farming on arable land and rehabilitation of resultant salt-affected soils/integrated soil management for sustainable use of salt-affected soils 2000
Also available in:
No results found.The development of agricultural technologies and a better appreciation of the existing but under-utilised knowledge of resource management will be crucial in meeting the ecological needs and in achieving the anticipated food demands of the growing population in the future. The greatest challenge for the coming decades lies in the fact that the production environments are unstable and degrading. Land degradation is proceeding so fast that unless policies and approaches change, many countries will not be able to achieve sustainable agriculture in the foreseeable future. Soil salinization has been identified as a major process of land degradation. The greatest technical causes of decreasing production on many irrigated projects particularly in arid-semi-arid areas, or failure of large areas in rainfed agriculture, are waterlogging, salinization and sodication.

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -
Brochure, flyer, fact-sheetBrochureGlobal map of salt-affected soils
GSASmap v1.0
2021Also available in:
No results found.Naturally saline or sodic soils host valuable ecosystems, including a range of rare plants, that are adapted to extreme conditions. However, salt-affected soils may develop quickly in response to human activities. Soils may thus become affected by salinity and sodicity due to inappropriate management or through saline water intrusion from sea, river, or groundwater and undergo a rapid decline of health, losing their capacity for biomass production, natural filtration, carbon sequestration, and other necessary ecosystem functions. The Global map of salt-affected soils (GSASmap) is an important tool for identifying salt-affected soils where sustainable soil management practices should be adopted to halt salinization and a foundation for launching a monitoring framework to track soil salinization and sodification and move into early detection and management. -
Book (stand-alone)Technical bookGlobal Soil Organic Carbon Map (GSOCmap) Version 1.5
Technical report
2020Also available in:
No results found.GSOCmap is the first global soil organic carbon map ever produced through a consultative and participatory process involving member countries, which makes this map totally new and unique. In fact, the map was prepared by member countries, under the guidance of the Intergovernmental Technical Panel on Soils and the Global Soil Partnership Secretariat. Countries agreed on the methodology to produce the map and were trained on modern tools and methodologies to develop national maps. The Global Soil Partnership then gathered all national maps to produce the final product, ensuring a thorough harmonization process. This technical report is a companion report to the GSOCmap V1.5. It presents methodologies and process of compiling the Global Soil Organic Carbon Map.
