“…The EC and TDS generally showed lower values in the dry than in the wet season. This might be mainly due to the increase in rainwater and concomitant ion dilutions in the wet season as supported by the previous works [ 87 , 88 ]. The nitrate levels during the rainy period showed an increment especially, in springs near settlements and shallow wells.…”

“…The Daihai Lake Basin includes a large farmland area (Supplementary Figure 1 in Supplementary material) 10.3389/fevo.2022.1005289 (Liang et al, 2021), and the water resources in the basin play an important role in agricultural development. Excessive salinity in irrigation water can cause soil salinisation, whereas high Na concentrations can cause soil alkalinisation, compaction, and reduced permeability (Abbasnia et al, 2018;Bouimouass et al, 2022). Therefore, EC, SAR, Na%, and PI were used to comprehensively evaluate the suitability of water for agricultural irrigation.…”

“…The main hydrochemical process can be further determined by calculating the ratio of cations to anions in water (Yang et al, 2016;Bouimouass et al, 2022). For example, during the dissolution of halite, the ratio of Na + to Cl − is 1:1 (Xiao et al, 2014;Ren et al, 2020).…”

Understanding the water quality and its influencing factors of different water bodies is essential for managing water resources in closed inland lake basins in semi-arid regions. However, generally, groundwater or surface water is assessed separately, and the differences among different water bodies are neglected. This study assessed the water quality and its influencing factors of different water bodies in the Daihai Lake Basin (a closed inland lake basin in a semi-arid region) by analysing the hydrochemical data of groundwater, and spring, river, and lake waters in the dry and wet seasons. The dominant hydrochemical type of groundwater (81.48%), spring water (80%), and river water (83.33%) was HCO3–Ca•Mg, while that of lake water was Cl-Na (100%). Groundwater, spring water, and river water were suitable for drinking and agricultural irrigation; however, the groundwater quality was worse in the wet season than in the dry season. Na+ and Cl– majorly affected the lake water quality. The mean NO3– concentration in groundwater was 28.39 mg/L, and its non-carcinogenic hazard quotient indicated that high risk areas were mainly distributed in Tiancheng and northern Maihutu. The hydrochemical compositions of groundwater, spring water, and river water were mainly influenced by rock (silicate and carbonate) weathering and cation exchange, and agricultural activities were the main sources of groundwater NO3–. Moreover, the lake hydrochemical composition was mainly affected by evaporation and halite dissolution. Thus, groundwater NO3– pollution and lake water salinisation should be prioritised. These findings provide a more thorough understanding of water quality and its influencing factors in the closed inland lake basin in the semi-arid region, and can be used to develop the protection of ecosystems and water resources management strategies in the Daihai Lake Basin.

“…Traditional resources management in oases have favored practices that maintain agricultural biodiversity (Aksoy & Oz, 2020) and ecosystem rehabilitation (Madejón et al, 2011). It reinforces the connectivity of green landscapes (Skokanová et al, 2020) and sustains groundwater (Bouimouass et al, 2022). Such agrosytems in oases facilitate trans-Saharan trade and allowed the development of cities and historic business centers of visible cultural influence such as Tombouctou and Sijilmassa.…”

The study apprehends modern versus traditional land-use changes in the Moroccan oases. The traditional local knowledge and land-use that ensured ecological equilibrium for centuries is decreasing. Modern entrepreneuship practices are increasing and have risky environmental impacts. By using the spatial and factor analyses, we confirm the spatial disparities in the region and distinguish four different groups of communes (in high mountain communes, traditional agriculture favors resources’ conservation; downstream communes experience greater changes and ecological ruptures). The recommendations of the study include the need to rethink adopted development models and elaborate new actions that respect local specificities, consider environmental equilibrium and rehabilitate local ecosystems.
