“…Compared with the concentrations of PTEs in agricultural soil of Wuwei and Jiuquan cities in the Hexi Corridor 62 , 63 , the concentrations of Cu, Ni, Pb and V elements in agricultural soil of the four oases in the study area were lower. Similarly, the concentrations of Cu, V and Zn in the study area were much lower than the corresponding concentrations in the agricultural soil of the Bahariya Oasis, Egypt 64 .…”

As rapidly developing area of intensive agriculture during the past half century, the oases in the source region of the Tarim River have encountered serious environmental challenges. Therefore, a comparative analysis of soil pollution characteristics and source-specific risks in different oases is an important measure to prevent and control soil pollution and provide guidance for extensive resource management in this area. In this study, the concentration of potential toxic elements (PTEs) was analyzed by collecting soil samples from the four oases in the source region of the Tarim River. The cumulative frequency curve method, pollution index method, positive matrix factorization (PMF) model, geographical detector method and health risk assessment model were used to analyze the pollution status and source-specific risk of potential toxic elements in different oases. The results showed that Cd was the most prominent PTE in the oasis agricultural soil in the source region of the Tarim River. Especially in Hotan Oasis, where 81.25% of the soil samples were moderately contaminated and 18.75% were highly contaminated with Cd. The PTEs in the Hotan Oasis corresponded to a moderate level of risk to the ecological environment, and the noncarcinogenic risk of soil PTEs in the four oases to local children exceeded the threshold (TH > 1), while the carcinogenic risk to local residents was acceptable (1E−06 < TCR < 1E−04). The research results suggested that the Hotan Oasis should be the key area for soil pollution control in the source region of the Tarim River, and agricultural activities and natural sources, industrial sources, and atmospheric dust fall are the priority sources that should be controlled in the Aksu Oasis, Kashgar Oasis and Yarkant River Oasis, respectively. The results of this study provide important decision-making support for the protection and management of regional agricultural soil and the environment.

“…Pollution seems to be another important threat (8.1%), but it is localized only in specific situations, such as in the costal oases of Gabes (Tunisia) that is considered a pollution hotspot in the Mediterranean area due to the emissions of the phosphate treatment complex of Gabès-Ghannouche (Alaya-Ltifi and Selmi 2014), or in the Bahariya Oasis (Egypt) due to near iron ore mines (Baghdady et al 2018).…”

Traditional oases in Northern Africa as multifunctional agroforestry systems: a systematic literature review of the provided Ecosystem Services and of the main vulnerabilities

Traditional oases represent unique forms of adaptation to extreme environmental conditions, developed through the centuries by local farmers to support their livelihood, combining different crops (date palms, fruit trees, vegetables and fodder) with livestock breeding. Despite their social, economic and cultural importance, these agroforestry systems are currently facing multiple socio-environmental threats. The aim of the paper is to investigate the variety of Ecosystem Services (ES) and the main threats related to traditional oases in Northern Africa through a systematic literature review. The search returned 257 relevant papers published from 2005 to March 2022, mostly focusing on Tunisian oases (37%), followed by Algerian (23%), Moroccan (19%), Egyptian (17%), and Libyan (4%). Provisioning Services, in particular Genetic diversity, agrobiodiversity and biodiversity, are the most cited ES (36% of the papers) followed by Cultural Services, mainly represented by Traditional knowledge systems, cultural heritage and sense of place (17%), while Regulating Services are less considered. Results highlighted that water related issues (desertification, drought, salinization or overexploitation) represent the main threat, followed by decrease of agrobiodiversity, primarily due to the spread of monocultures of commercial date varieties, and by social transformations (depopulation, traditional knowledge and cultural heritage loss). The literature review proved that traditional oases are still crucial for the livelihood of local communities since they still provide many ES. Local experiences related to sustainable development and tourism, or innovative solutions to valorize local products and byproducts, could be important for replication in other traditional oases to contribute to the wellbeing of local communities and to the preservation of these agroecosystems.

“…Bahariya Oasis is a roughly oval valley representing the Bahariya depression which covers an area of about 2000km², 94km in length× 42km width, (Svoboda, 2004;Baghdady et al, 2018); with an elevation at base varying between 120 and 130m above sea level (Svoboda, 2004). The floor of Bahariya depression includes springs, lakes, Sabkhas (saline lands in the deepest areas in the depression), human settlements with cultivated areas, other settlements (e.g., El-Harra, El-Heiz, El-Qasr Mandisha, Qebala), and numerous fossil deposits (Refai et al, 2002;Svoboda, 2004;Baghdady et al 2018). The depression is surrounded by high scarps (ca.…”

T WO species of Bryaceae are recent records for the bryoflora of Egypt from Bahariya Oasis (Western Desert): Bryum klinggraeffi Schimp. and B. valparaisense Thér. In addition, Bryum dichotomum Hedw. is recorded for the first time from the study area. Thus the number of mosses known from Egypt becomes188 and from Bahariya oasis 14. The two recently recorded species are described and illustrated and details are given of the collection sites and habitats. Notes are also given on their wider distributions along with some floristic remarks.
