CA22144 - Sustainable use of salt-affected lands (SUSTAIN)

Salinisation, the accumulation of water-soluble salts in the soil, is one of the major causes of soil degradation affecting 833 million hectares of land and 1.5 billion inhabitants worldwide. However, these lands can be used by applying saline agriculture, involving soil, water and salt-tolerant crop management methods. Cultivation of salt-affected lands aids in addressing food and water security in the times of progressing climate change and population growth. As a result, there is an urgent need to create a network of research and practice and foster the sustainable use of salt-affected lands. 

This COST Action aims to build a global transdisciplinary network of scientific experts and engaged stakeholders in the field of salinity research in the context of food security, sustainability and the intensifying climate crisis. Our activities will focus on: (i) understanding responses to heterogeneous soil salinity and other combined stresses in the soil-rhizosphere-plant continuum; (ii) building a knowledge-base to improve water and soil management, and crop production on salt-affected lands; (iii) showcasing the total value of salt-affected lands and saline landscapes; (iv) connecting various stakeholders involved in saline agriculture; and (v) developing targeted policy frameworks for the proper salinisation management, bringing saline agriculture as a complementary component in the European food security agenda for coastal and inland salt-affected lands. Mutual knowledge exchange and sharing best practices will contribute to more sustainable use of salt-affected lands and enhance the resilience of the landscape as a whole.
