Adapting to salinity
Adapting to salinity has several gradations. The most common form is to select more salt tolerant crop varieties. When salinity effects become more severe, a shift to different crops occurs. In cereal production it is common to see a shift from wheat to barley. Another common shift is from vegetables to cotton. When salinity increases to levels where cash crop production is limited, a shift occurs to grasses and halophytes, usually in combination with an increased attention to livestock production. Other forms of adaptation are the shift from agriculture to industry, or rural population moving away to cities to find alternative forms of income.
