Soil salinization is a natural process resulting from the hydrogeological situation of semiarid and arid zones. Human-induced salinization is the result of suboptimal water management, typically the use of saline water and/or rise of saline groundwater. Irrigation is closely linked with salinization and 28percent of the total irrigated land is affected by human-induced salinization (table 4.). Increased soil salt concentration causes yield decline and in extreme situations can result in the cessation of cultivation. There is a long list of possible off-site effects of improperly managed irrigation projects which decline the environmental quality of the areas. The attitude towards the natural salt-affected soils depends on the differences in the need for new croplands worldwide. Where population pressure obliges the cultivation of new croplands or the establishment of new residential areas, the natural salt-affected areas, such as salt-deserts and saline lakes, continental saline and sodic forests, grasslands and marshes, maritime salt marshes and mangroves are threatened.
