Abstract

Twenty-first century is marked by many challenges regarding agro-ecosystems, such as environmental pollutions, scarcity of water, and increased salinization of soil and water. Population bomb (increasing human population) and reduction in land available for cultivation are two threats to agricultural sustainability. In this situation, demand for cultivable land increases. However, environmental degradation factors such as erratic rainfall, extreme temperatures, drought and floods, high winds, and soil salinity have affected the production and cultivation of agricultural crops. Among these, soil salinity is one of the most devastating environmental stresses, which causes major reductions in cultivated land areas, crop productivity, and quality. Soil salinity further impacts the general public, particularly farmers, through its effect on agriculture. Therefore, it is necessary to find the causes of soil salinity and its impact (economic and environmental) on crop production in saline soils given the increasing farming costs. Thus, the main focus of the present chapter is to provide an overview of the past and present studies on salinity and its economic impact on the agricultural system.
