“…Soil salinity has severe effects on plant growth and development and plant productivity in arid and semiarid regions worldwide ( Kochian et al, 2015 ; Krasensky & Jonak, 2012 ; Ryu & Cho, 2015 ). The increase in soil salinity and acidification is due to poor irrigation practices, improper fertilizer application, industrial pollution, and seawater intrusion caused by global warming ( Gaudio et al, 2015 ; Ding et al, 2020 ). In particular, growers are advised to apply large amounts of chemical fertilizers for high yields during long-term vegetable production processes.…”

We investigated the effects of low pH on the photosynthesis, chlorophyll fluorescence, and mineral contents of the leaves of ginger plants under salt stress. This experiment involved four treatments: T1 (pH 6, 0 salinity), T2 (pH 4, 0 salinity), T3 (pH 6, 100 mmol L−1 salinity) and T4 (pH 4, 100 mmol L−1 salinity). This study showed that photosynthesis (Pn, Gs, WUE and Tr) and chlorophyll fluorescence (qP, Φ PSII, and Fv/Fm) significantly decreased under salt stress; however, all the parameters of the ginger plants under the low-pH treatment and salt stress recovered. Moreover, low pH reduced the content of Na and enhanced the contents of K, Mg, Fe and Zn in the leaves of ginger plants under salt stress. Taken together, these results suggest that low pH improves photosynthesis efficiency and nutrient acquisition and reduces the absorption of Na, which could enhance the salt tolerance of ginger.

Organic agricultural practices are sustainable alternatives to chemical methods. This article highlights the major challenges faced by environmentalists, social workers in popularizing organic agriculture as well as its positive field application. The primary soil parameters (pH, alkalinity, electrical conductivity, soil, organic carbon, soil texture, and available N, P and K) are compared between global coastal agricultural soils. Organic farming practices adopted in different regions were also focused in this article. Sundarbans is the world’s largest contiguous mangrove ecosystem, largest delta, abode of mangrove dwelling tigers and Indian part is the home of 4.6 million natural disaster vulnerable populations. This work showcases success story of organic farming by 84 families of Indian Sundarbans since 2012, with use of vermicompost, biopesticides (neem oil) and natural microbe augmentations (Trichoderma sp), as a part of a socio-environmental intervention project. This intervention resulted in increased yield in both kharif season (10-12%) and rabi season (5-10%) by 2017.

“…Another cluster of papers pertaining to this group tackled the saltwater intrusion delineation by using GIS weighting and rating methods, in which simple overlay maps methods are employed to estimate the vulnerability of a given coastal aquifer to salinization such as the GALDIT method (GALDIT is the acronym formed from the highlighted letters of the parameters used) [130][131][132][133][134][135], even with modifications to account for surfacegroundwater interactions [136], or by using GIS and water quality index interpolation methods to propose maps of vulnerability to salinization [137][138][139][140][141][142][143]. The main advantage of these methods is the relative easiness to handle high amount of data (i.e., spatially continuous precipitation and evapotranspiration data, land use maps, etc.…”

The Issue of Groundwater Salinization in Coastal Areas of the Mediterranean Region: A Review

The Mediterranean area is undergoing intensive demographic, social, cultural, economic, and environmental changes. This generates multiple environmental pressures such as increased demand for water resources, generation of pollution related to wastewater discharge, and land consumption. In the Mediterranean area, recent climate change studies forecast large impacts on the hydrologic cycle. Thus, in the next years, surface and ground-water resources will be gradually more stressed, especially in coastal areas. In this review paper, the historical and geographical distribution of peer-review studies and the main mechanisms that promote aquifer salinization in the Mediterranean area are critically discussed, providing the state of the art on topics such as actual saltwater wedge characterization, paleo-salinities in coastal areas, water-rock interactions, geophysical techniques aimed at delineating the areal and vertical extent of saltwater intrusion, management of groundwater overexploitation using numerical models and GIS mapping techniques for aquifer vulnerability to salinization. Each of the above-mentioned approaches has potential advantages and drawbacks; thus, the best tactic to tackle coastal aquifer management is to employ a combination of approaches. Finally, the number of studies focusing on predictions of climate change effects on coastal aquifers are growing but are still very limited and surely need further research.
