Impacts of salinization caused by sea level rise on the biological processes of coastal soils - A review

Abstract: Soil salinization caused by sea level rise threatens coastal agricultural soils and geochemically important wetlands worldwide. The aim of this review is to outline expected changes in soil biological activity by discussing the combined effects of salt stress and flooding on plants productivity and soil microbial communities, which determine consequences on fluxes of C, N and P. Finally, it outlines the expected repercussions on greenhouse gases emissions. The prediction of outcomes is made difficult by the co… Show more

“…Exceeding these tolerances can lead to osmotic stress, affecting their ability to maintain proper internal balance. Changes in salinity can also impact the distribution and abundance of different species, potentially leading to shifts in the composition of aquatic communities [29,31,32]. In situations where aquatic life and soil composition are adversely affected, this would have an impact on food availability considering that fish serve as a major food source in these communities [27,29,30,33].…”

“…Saltwater intrusion into freshwater wetlands will become increasingly widespread and severe with climate change and will have many ramifications for wetland plant, animal, and microbial communities, with important implications for biogeochemical export (e.g. of nitrogen) and greenhouse gas emissions [ 10 , 19 , 83 ]. Sulfate is often cited as a key regulator of saltwater intrusion effects on methane emissions [ 14 , 15 , 18 , 24 , 84 ], but its role has not been explicitly tested.…”

“…The salinity stress that can reduce crop growth is stress on soil salinity. Salinity stress in coastal land is affected by high salt concentrations in the soil due to salt accumulation (Mazhar, 2022). Salinization of the soil causes an increase in soil osmotic pressure and interferes with the absorption of water and nutrients in crops (Machado et al, 2017).…”
