How a park works in the desert

How do you water a million trees in a desert?
Riyadh gets about 101 mm of rain a year and loses nearly twenty times that to evaporation. The park's answer is a loop of recycled water, deep soil and a very large treatment plant.

A valley where a runway used to be
The park stands on Riyadh's old airfield. Its designers are cutting the flat ground into branching wadis that shade, hold water and carry floods.

Shade, breeze and cool air
A walk through the layers the park uses against Riyadh's heat: shaded paths, planting zones, local-stone walls and a 60,000-tonne district cooling system.
