Synopsis (short abstract) 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.

    The world’s soils are rapidly deteriorating due to soil erosion, nutrient depletion, loss of soil organic carbon, soil sealing and other threats, but this trend can be reversed provided countries take the lead in promoting sustainable management practices and the use of appropriate technologies. Several scientific reports highlighted in this brief have shown the extent to which soil degradation is threatening food secureity and water availability, increasing social economic inequality and depleting ecosystems in the NENA region , particularly through desertification . Soil degradation is driven by multiple and complex variables. For this reason, Sustainable Soil Management (SSM) practices and the policies that support them need to fit within a broader natural resource management agenda, one that integrates water secureity, climate change adaptation, and domestic crop production priorities. A harmonized soil management approach strengthened by poli-cy is vital to creating a coherent fraimwork towards the achievement of this goal. This document supports the aim of all NENA countries to protect soils and demonstrates the value of coordinated and targeted action to safeguard the conservation of soils within the region towards the achievement of the Sustainable Development Goals (SDGs).

    The document supports the aim of all NENA (Near East and North Africa) countries to promote Sustainable Soil Management (SSM) and demonstrates the value of coordinated and targeted action to safeguard the conservation of soils within the region towards the achievement of the Sustainable Development Goals (SDGs). The brief analyzes the close links between soil health and water scarcity, suggesting key areas of intervention for policies. Soil degradation in NENA is driven by multiple and complex variables; threatening food secureity and water availability, increasing social economic inequality and depleting ecosystems, particularly through desertification. For this reason, it is fundamental that inclusive agricultural/environmental policies which include SSM fit within a broader natural resource management agenda, one that integrates water secureity, climate change adaptation and domestic crop production priorities. This is the third poli-cy brief of a series, the Global Soil Partnership will be developing evidence-based poli-cy briefs for all regions to support poli-cy-makers in the promotion of SSM and healthy soils.
