I just stumbled on a very cool tool from the folks at ESRI using U.S. government Landsat imagery (yay public goods! background here) allowing you to look at vegetation change over time. Here’s a graphic look at water use in Albuquerque 1990-2010. The bits in green are places where vegetation has increased. The bits in that reddish colour (magenta?) show where vegetation has decreased. It’s outdoor water conservation, visualized:
This covers a time period during which per capita water use has decline from ~250 gallons per person per day to something around 150. The green patch in the upper right is an area of affluent sub-urban sprawl since 1990. The reddish blotch in the center is the already developed area of town (the “northeast heights” for ABQ folks). Fewer trees and lawns.
