Climate change due to global warming has far major impacts on the increasing salinity not only in the oceans (https://www.google.se/amp/s/amp.theguardian.com/environment/2008/oct/27/climate-change-water?client=safari) but also on land-water resources on planet Earth (http://www.sciencedirect.com/science/article/pii/S2210600611000086).
Such impacts will further accelerate the degradation of freshwater resources on land with major negative impacts on agriculture and health of humans. Increasing salinity of natural drinking water sources has been reported as one of the many problems that affect low-income countries around the world. Yet, this has not been fully explored. This problem is exacerbated by rising sea-levels, owing to climate change, and other contributing factors, like changes in decreasing fresh water flow from rivers due to construction of dams for hydroelectric power generation, waste from desalination plants and increased shrimp farming along the coastal areas. In some countries, desalination plants are used to partly remove salt and other minerals from water sources, but this is unlikely to be a sustainable option for low-income countries affected by high salinity (http://www.sciencedirect.com/science/article/pii/S2210600611000086).
Climate change will make seas more salty where “the rich will be more richer”, i.e. wet regions will become wetter and dry regions will become much drier. For example the Mediterranean area will become drier, increasing “aridity” and enhanced salinity in the water.
Soil salinization in irrigated areas is a degradation process that harms both crop productivity and environment. Climate change in the Mediterranean region will be accompanied by changes in the precipitation patterns and increases in the average temperatures. These new conditions could affect the soil salt build-up due to a decrease in the salt leaching ability of rainfall and because of an increase of the evapotranspiration due to the increase of temperature (https://www.researchgate.net/file.PostFileLoader.html?id=5794725f5b49523fe643b8e1&assetKey=AS%3A387281023193089%401469346399460).
