Susceptibility of Terrestrial Ecosystems to Degradation
The Interactive Effects of Land Use and Climate Change

The desiccation of salt lakes, driven by both climate change and unbalanced water use by agricultural sectors in arid and semiarid regions, is increasingly leading to the formation of new dust sources around the world. The detachment and wind transport of saline aerosols not only influence cloud formation at higher altitudes but also reduce soil fertility when deposited on agricultural lands, thereby threatening food security. This project focuses on the role of fine aerosol particles, originating from both degraded saline agricultural lands and the dried bed of Urmia Lake (northwest Iran), in cloud formation. It aims to develop a proposal to enhance soil organic matterβ€”a key indicator of soil qualityβ€”in a semi-arid context, emphasizing regenerative land management practices.
