“…Another major factor limiting agricultural expansion in Mediterranean countries is the diminishing quality of water, e.g., through salinization. In North African countries, higher temperatures are linked to geographical location, leading to a higher evaporation in comparison with European and Middle Eastern regions; this is one of the most important factors increasing the groundwater’s salinity, next to seawater intrusion and geohydrological conditions [ 2 , 3 , 4 ]. Additionally, soil salinity is the second major cause of land degradation after soil erosion and has been a cause of agricultural decline for centuries, causing yield decrease for many crops and leading to desertification [ 5 ].…”

The use of saline water resources in agriculture is becoming a common practice in semi-arid and arid regions such as the Mediterranean. In the SmaCuMed project, the desalination of brackish groundwater (TDS = 2.8 g/L) for the irrigation of Argan trees in Essaouira, Morocco, to 2 g/L and 1 g/L (33% and 66% salt removal, respectively) using low-pressure reverse osmosis (LPRO) (p < 6 bar) and membrane capacitive deionization (MCDI) was tested at pilot scale. MCDI showed 40–70% lower specific energy consumption (SEC) and 10–20% higher water recovery; however, the throughput of LPRO (2.9 m3/h) was up to 1.5 times higher than that of MCDI. In addition, both technologies were successfully powered by PV solar energy with total water costs ranging from EUR 0.82 to EUR 1.34 per m3. In addition, the water quality in terms of sodium adsorption ratio was slightly higher with LPRO resulting in higher concentrations of Ca2+ and Mg2+, due to blending with feed water. In order to evaluate both technologies, additional criteria such as investment and specific water costs, operability and brine disposal have to be considered.

“…These inquiries, often meticulous and enlightening, tend to concentrate on isolated instances, which, while valuable, limit broader understanding. Contrastingly, comprehensive comparative studies that examine groundwater's chemical attributes across multiple coastal aquifers in the region are relatively rare [15], [16], [17], [18], [19], [20].…”

Coastal aquifers, essential for agriculture, domestic, and industrial water supply, face significant sustainability challenges, particularly in Mediterranean regions, due to the adverse effects of human activities, climatic threats, and natural geological conditions causing salinization. This paper synthesizes findings from studies on three Mediterranean coastal aquifers— the Pleistocene aquifer in the Gaza Strip, the karstic aquifer in Bokkoya, and the MioPlio-Quaternary aquifer in Djeffara of Medenine—highlighting the escalating deterioration due to over-exploitation and arid conditions. It compares the methodologies used in these studies, such as statistical analysis, geostatistical modeling, and groundwater quality indices, to assess groundwater quality and address salinization challenges. This review aims to identify methodological limitations and propose strategies to fill research gaps, particularly in combating seawater intrusion, to enhance the sustainable management of these critical water resources.
