Water and soil salinity affect food production and food security worldwide. Water salinity is a causal factor for soil salinity. Soil salinity beyond a certain threshold level can be detrimental to crop production. Soil salinization occurs when salt accumulates in the upper layers of soil, and it is generally prevalent in areas where evaporation exceeds precipitation, mostly in water-deficit conditions.
