“…For example, a large unmet water demand has been projected for future scenarios in the valley of Seybouse in East Algeria (Aoun-Sebaiti et al 2014), and similar conclusions were drawn for Wadi El Natrun in Egypt (Switzman et al 2018). Modelling studies have indicated long-term decline in available water and increasing risk of water shortages -for example, for oases in Morocco (Johannsen et al 2016;Karmaoui et al 2016), the Dakhla oasis in Egypt's Western Desert (Sefelnasr et al 2014) and for the large Upper Mega Aquifer of the Arabian Peninsula (Siebert et al 2016). Mainly due to the risk of water shortages, Souissi et al (2018) classified almost half of all farmers in Tunisia as non-resilient to climate change, especially those relying on tree crops, which limit opportunities for short-term adaptation actions.…”

While global-scale studies provide information for any region, there are numerous studies that focus on sub-continental scales, providing more in-depth analysis and understanding. Regional and local studies are important to detect location-specific trends in desertification and heterogeneous influences of climate change on desertification. However, these regional and local studies use a wide variety of methodologies, making direct comparisons difficult. For details of the methodologies applied by each study refer to the individual papers.Recent work has also found albedo in dryland regions can be associated with soil surface communities of lichens, mosses and cyanobacteria (Rodriguez-Caballero et al. 2018). These communities compose the soil crust in these ecosystems and due to the sparse vegetation cover, directly influence the albedo. These communities are sensitive to climate changes, with field experiments indicating albedo changes greater than 30% are possible. Thus, changes in these communities could trigger surface albedo feedback processes (limited evidence, high agreement) (Rutherford et al. 2017).

“…Deep groundwater resources are a potential unconventional source of water and potable water that can address water scarcity globally (UN-Water, 2020). Fresh and brackish (low salinity) deep groundwater, both from confined and fossil aquifers, have been found onshore and along coastlines down to depths of several kilometers, hosted in both clastic and carbonate aquifers worldwide (Margat & Van der Gun, 2013; Van der Gun, 2022), such as: the Nubian Sandstone Aquifer across Chad, Egypt, Libya, and Sudan, down to 3500 m (Voss and Soliman, 2014;Ruden, 2016); the Upper Mega aquifer system of the Arabian platform, at >400 m of depth (Siebert et al, 2016); the Great Artesian Basin in Australia, down to 2000 m of depth (Habermehl, 2020); Tanzania coastal aquifer at 1000 m of depth (Moe et al, 2017); the Horn of Africa aquifer at >400 m of depth (Quiroga et al, 2022), among others. Many of these large deep groundwater systems are considered as the result of meteoric water recharge during previous geological epochs, e.g.…”

Deep groundwater resources around the world represent an important potential unconventional source of water. Here we document an extensive (17.3 km3) fresh/brackish groundwater body preserved in a deep (between 800 and 2100 m) carbonate platform aquifer in southern Sicily (Italy), by using deep well data and a 3D hydrogeological modelling. We attribute the distribution of this fossil groundwater to topographically-driven meteoric recharge driven by the Messinian sea-level drawdown, which we estimate to have reached 2400 m below present sea level in the eastern Mediterranean Basin. The discovery of such an extensive and deep freshened groundwater has significant implications in terms of resource potential for southern Sicily and other Mediterranean coastal regions, that share similar geological setting and water scarcity issues.
