Is “the lawn” the final American frontier?
Sometimes I think that the old man across the street who sits on a huge mower to mow a relatively small lawn every five days or so is longing to be a farmer. I feel for him, and for the rest of us who must put up with the awful noise, made even worse, in the fall, by his leaf blower. P.S. No wonder he’s deaf!
Meanwhile, in our little two-house ecopod, we’ve removed the front lawn of one house in favor of berry and nut-bearing bushes and turned most of the back yard of the other house into a chicken yard. Still not sure what to do with the other front yard, or the strips between streets and GANG garden. We mow them both with a hand mower.
The study comes as Californians wrestle with how to care for their lawns in the midst of a four-year drought.

Americans’ lawns now cover an area three times larger than any irrigated crop in the U.S.
According to a new study from NASA scientists in collaboration with researchers in the Mountain West, there is now an estimated total of 163,812 square kilometers, or more than 63,000 square miles, of lawn in America — about the size of Texas. Here’s the map:
The study was not about the growth of lawns, however. Instead, it focused on their impact on the environment and water resources. The researchers found that well manicured lawns can act as carbon sinks — meaning they would help mitigate climate change by removing carbon dioxide from the atmosphere.
However, maintaining a well-manicured lawn uses up to 900 liters of water per person per day and reduces sequestration effectiveness by up to 35 percent by adding emissions from fertilization and the operation of mowing equipment.
“If the entire turf surface was well watered following commonly recommended schedules there would. . . be an enormous pressure on the U.S. water resources, especially when considering that drinking water is usually sprinkled,” the researchers found. “At the time of this writing, in most regions outdoor water use already reaches 50-75 percent of the total residential use.”
The study comes as Californians wrestle with how to care for their lawns in the midst of a four-year drought. Southern California’s water district has begun a “cash for grass” system that’s proven highly effective, with all $340 million initially set aside to convince homeowners to replace lawns with desert landscaping getting used up.
And Los Angeles city officials have begun sending out complaints to the “top 1 percent of water users” urging them to change their watering habits.
“It was a wake-up call,” Warren Dern, a Sherman Oaks resident with a 7,000-square-foot lawn,told the L.A. Times’ Matt Stevens in June. “I was like, ‘Wow, maybe we’re part of the problem.’”
The NASA researchers did not address the drought in their paper, but did find that it will likely be some time before we see a significant decrease in lawn acreage.
“Because of demographic growth and because more and more people are moving towards the warmer regions of the country the potential exists for the amount of water used for turf grasses to increase,” they write.
And Euromonitor’s Ryan Tuttle has projected U.S. lawnmower growth is on track to recapture its pre-recession levels thanks to the housing recovery and what he said was a “continued emphasis on a well-manicured yard.”
While the overall volume of mowers could come down moving forward thanks to younger adults’ preference for living in denser areas, as long as there are “older and better funded consumers” in the market sales will continue to be steady.
