This subject identifies a number of critical issues affecting irrigation in a semi-arid environment: irrigation water (sources, variability, and management) and drought (climate variability, change and adaptation mechanisms). Critical environmental issues arising from irrigation: drainage through the soil profile, the accumulation of salt and the effects on river and land systems.
