“…Low organic carbon and dissolved oxygen contents, low turbidity, and silt density index are other positive characteristics of the abstracted saline or brackish water, which play a role in the selection of these sources to feed RO desalination units over direct seawater intake [51,52]. According to Miller [53] and Stein et al [54], the majority the seawater desalination costs using RO re attributed to the high energy consumption. The total cost and energy consumption of brackish water is less than 50% of the seawater desalination method.…”

Seawater intrusion (SWI) is one of the most challenging and widespread environmental problems that threaten the quality and sustainability of fresh groundwater resources in coastal aquifers. The excessive pumping of groundwater, associated with the lack of natural recharge, has exacerbated the SWI problem in arid and semi-arid regions. Therefore, appropriate management strategies should be implemented in coastal aquifers to control the impacts of SWI problems, considering acceptable limits of economic and environmental costs. The management of coastal aquifers involves the identification of an acceptable ultimate landward extent of the saline water body and the calculation of the amount of seaward discharge of freshwater that is necessary to keep the saline–freshwater interface in a seacoast position. This paper presents a comprehensive review of available hydraulic and physical management strategies that can be used to reduce and control SWI in coastal aquifers. Advantages and disadvantages of the different approaches are presented and discussed.

“…On the other hand, rising sea levels due to global warming have further caused the instability and salinization of aquifers (White et al, 2005;Woodworth et al, 2009;Sanford and Pope, 2010). Under these conditions, even pumping saline groundwater to desalinate the aquifer not only does not solve the problem but also causes a freshwater-saltwater interface to move towards the aquifer (Stein et al, 2019). Therefore, it is necessary to determine the optimal pumping rate, especially in coastal areas, to conserve the strategic freshwater resources of coastal aquifers using a combination of simulation models and optimization techniques.…”

In this study, after simulating five years of saltwater intrusion with SEAWAT package in Astaneh-Kouchesfahan coastal aquifer, Iran, 19 strategies, including managerial, structural, and combined strategies, were investigated to reduce the saltwater intrusion. Since managerial solutions cause users' dissatisfaction and structural solutions increase the costs, two-player game theory was used to identify the most appropriate solution. According to the results obtained from game theory, the two strategies of artificial recharge and underground dam had the greatest impact on preventing the saltwater intrusion with the highest satisfaction of stakeholders, so that they decreased the saltwater intrusion from 740 m by 150 and 300 m, respectively, after five years.Therefore, the combined simulator-optimizer method presented in this study can evaluate various solutions, and the most appropriate solution can be proposed with the lowest cost and maximum satisfaction for the sustainable management of coastal aquifers.

“…Saline-alkali land had seriously affected the arable land area and food security of all countries. Australia (Stein et al 2019), India (De Deckker et al 2019Singh 2018), Egypt (Minhas et al 2019) and other countries had carried out research and obtained good results since the 1930s. Developing strategies to make use of saline land would be crucial for addressing the problem of insufficient cropland and meeting the challenge of providing food security for the projected global population of 9.3 billion people by 2050 (Liu et al, 2021).…”

To further study saline-alkali soil cultivation, the terminal-restriction fragment length polymorphism (T-RFLP) was used to analyze the effects of different salt concentrations on the denitrification functional genes nirS and nosZ after collecting different soil samples and extracting total soil DNA. The results showed that the variation range of nirS gene abundance was concentrated in 14 segments, the nosZ gene abundance was concentrated in 9 segments. The abundance of nirS gene in paddy soil of different concentrations was higher than nosZ, and the activity of the nirS gene was higher. Diversity index analysis showed that sample Ⅰ was significantly different from Ⅲ and Ⅴ in the Shannon index of the nirS. Sample Ⅰ and Ⅳ were significantly different from Ⅲ in Simpson index. Except for the significant difference between Ⅲ and Ⅰ, Ⅱ, Ⅳ, and Ⅴ, there was no difference between the other four samples significant in Pielou index. The difference between sampl Ⅰ and Ⅴ was extremely significant in Brillouin index.The Shannon index, Simpson index and Pielou index of nosZ gene were not significantly different, sample Ⅱ and Ⅲ, Ⅳ, Ⅴ were significantly different in Brillouin index. The diversity of nirS gene was more affected by the salt concentration, and the nirS gene was more widely distributed than nosZ in soil with different salt concentrations. It indicated that nirS -mediated nitrite reductase played an important role in salinity affected soil environment.
