Book (stand-alone)Thematic 1: Farmers’ guidelines on soil and water management in salt-affected areas 2023
Also available in:
No results found.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. -

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. -

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.
