^ There's arguments against the shade approach. One big one is that many shady trees are also tremendously hyperallergenic. Phoenix was once known as a haven for asthmatics and the like but through invasive species--both deliberate and not--we've completely eliminated what could have been a desert paradise if we knew what we were doing then.

The modern attempts at this are indeed short sighted at sparse. I'll never quite understand why shade is so important in Arizona urban projects but no landscape architect ever gets it. Who hires these people?
