How Much Water Does It Take to Grow Grass In The Desert?

As a non-food and fiber crop, lawns provide the public with benefits to urban life that are less tangible, such as mitigation of heat island effects, dust and erosion control, shade, providing a cool and safe surface for all sorts of exercise and athletic activities, and space for outdoor social gatherings. Despite the economic and social importance and continued public demand for green areas, turfgrass water consumption is a major point of political debate, particularly in arid and semi-arid regions where it is estimated that over 50% of summer urban domestic water use goes to outdoor watering. However, research has shown that turfgrass is irrigated well beyond what is necessary to survive and perform as expected. All aspects of estimating true turfgrass irrigation water requirement will be covered and measures for water conservation will be discussed.
