| Soils are key components of drylands, supporting these highly vulnerable ecosystems that cover almost half of global land surface and are home to more than one third of the global population. The latest climatic data available indicate that aridity has increased globally in the last seven decades, and drylands are expected to further expand because of global warming. In this communication, we will present an updated description of the major physical and chemical properties of dryland soils, with special emphasis on organic and inorganic C contents. For this purpose, we used the WISE30sec geo-database, which to the best of our knowledge represents the most recent and detailed global soil inventory currently available. We found that dryland soils store about 650 Pg of organic C and 1200 Pg of inorganic C to 2 m. This information is essential and highly needed to face the challenges of increased population, food security, land degradation, and climate change in global drylands. | |
