The availability of freshwater for agricultural use is declining in many areas of the world. This is the reason for the increasing use of lower quality or of saline water for crop production. Prolonged use of saline water severely affects the irrigated soils, which contributes to the global land degradation process and has direct impact on biomass production. For this reason, reduction of the spread of salinization, revitalization of salinized areas and introduction of salt tolerant high-yielding crops are important issues. The potential role of halophytes in the management of salinity problems of arid lands is investigated at length nowadays; some of these have produced promising forage crops. This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline habitats.
