When California was strangled by drought, the city of Los Angeles was offering homeowners

cash to replace their lawns with landscaping that was less thirsty,

because water just evaporates from overwatered lawns.

But how much?

So that turned out to be a lot of water.

Diane Pataki, an ecologist at the University of Utah.

Turns out to be 70 billion gallons of water a year.

Pataki and her team got that number using a combination of real-world sensor data and modeling.

And they found that of water wasted specifically in urban landscaping,

lawns were to blame for three quarters of it,

with LA's 6 million trees accounting for the rest.

The study also uncovered something these ecologists were not expecting to study, economic disparity.

The amount of vegetation is really closely related to affluence.

And so in LA, that means that wealthy neighborhoods actually have twice the evapotranspiration

of poor neighborhoods. Meaning low-income neighborhoods not only miss out on the greenery, but also the

natural built-in cooling effect of evapot transpiration. The findings are in the journal Water Resources
