    The book of proceedings of the GSAS21 contains the papers presented during the

    Global Symposium on Salt-affected Soils

    that was held on 20-22 October 2022. The papers provide the up-to-date scientific knowledge and practical solutions for mapping, assessment, rehabilitation and sustainable management of saline and sodic soils as well as policy recommendations on actions needed to manage salt-affected soils, prevent soil degradation, and to upscale good practices and technologies on these soils.

    Salinization is the most severe threat to soils in the NENA region after soil erosion. Indeed, more than 11 percent of the region’s soils are affected by various levels of soil salinization Salinity has direct effects on the growth and development of plants. Sodic conditions may cause important deterioration of the soil physical properties, indirectly affecting crop growth via increased surface crusting, poor water infiltration, and reduced root zone aeration. The Voluntary Guidelines for Sustainable Soil Management (VGSSM) provide recommendations on how to prevent the development of salt-affected soils. If soils are already degraded and prevention is no longer an option, excess salts can be removed from the soil surface and the root zone using a variety of techniques. Under all conditions, the sustainable management of soil resources is key in preventing and combating salinization.
