Water Conservation in Arid and Semi-Arid Regions

2017-1-15  Water resources in arid and semi-arid areas are very scarce due to the low rainfall and high evaporation. This complicates the supply of water for domestic, industrial and agricultural uses. Water managers in arid areas must therefore have a very clear understanding of the constraints and opportunities of the available water resource base.
