Agriculture in water-limited areas is an integral part of regional and global food security.Indeed,food production has increased dramatically in the arid and semiarid areas thanks to the advances in agronomy,genetics and engineering.Irrigation technology,fertilizers and pesticides,and soil management have revolutionized agriculture in water-limited areas.However,water scarcity remains the greatest challenge for agriculture and usually is also the cause for other socioeconomic and environmental problems.Moreover,water scarcity in an area often coexists with low water use
Agriculture in water-limited areas is an integral part of regional and global food security.Indeed, food production has increased dramatically in the arid and semiarid areas thanks to the advances in agronomy, genetics and engineering. Irrigation technology, fertilizers and pesticides, and soil management have revolutionized agriculture in water-limited areas. Host, water scarcity remains the greatest challenge for agriculture and usually is also the cause for for other socioeconomic and environmental problems. Moreover, water scarcity in an area often coexists with low water use
