Los Angeles Isn’t London, and Other Things that are Wrong with California

Recently I was browsing Imgur and came across a set of images depicting the current drought conditions in California.
When I looked through the comments, I saw a few gems:
“See this?…See this? This is why I think lawns should be illegal in drought areas. You want a lawn? Move to East…”
“Hey let’s build golf courses in the desert!”
“A**holes need to realize that lush green lawns work in the SE, not SW. Sauce: I’m a f***ing city planner.”
Which reminded me of something that bothers me about California: that 38 million people live in an area that can probably sustainably support something more like one million, and lawns are just one example of cultural artifacts that have made it to California that were based on an entirely different climate. Let me explain:Well, yes, but so what? Well, some cultural features, including the lawn and the detached home, are cultural aspects that arose in England, partially because of its climate, and got appropriated to California in such a way that the environment had to be altered to support it.
The lawn became popular among the English nobility in the late Middle Ages. It arose there because England’s wet weather and moderate temperatures made it ideal for keeping grass green without the need to water, and because before the invention of the mower in 1830 one needed an army of peasants to trim the lawn with scythes. The lawn quickly dispersed to Ireland, France, and the Low Countries, other places with a suitable climate.
When the lawn hopped the pond with the earliest English colonizers of the Americas, it fared decently in the Northeast, which despite having a humid continental climate rather than England’s oceanic, still had sufficient rain and temperatures, although the winters were usually cold enough for the grass to go dormant. Some New England towns had lawns that were commonly owned and maintained, leading to the New England Common. But at this point the lawn could barely even survive in the American South, where higher temperatures made it too warm to keep the grass from turning brown.
The lawnmower was what made the lawn accessible to the land-owning middle class. They became more common with the implementation of the 40-hour work week, and lawn care was promoted as a form of relaxation during the Depression. It was only through irrigation that the lawn was able to leave the Northeast, and even then, only due to massive inputs of fertilizer that it was able to take root in the arid soils of the American Southwest.
Let’s take a closer look at climate. Here is a map of the oceanic climate, where the lawn originated:
These climates are most present in northern Europe, southern Chile and Argentina, southeast Australia, and New Zealand. It is truly barely present in North America, only making an appearance on the wet coasts of the Pacific Northwest around Seattle and Vancouver. Notably, it is not present in California. Let’s look at California’s climate map:
The Mediterranean climate, unsurprisingly, covers much of the Mediterranean, and as far east as Iran. Desert climates, largely uninhabited, cover much of northern Africa, the Middle East, central Asia, and Australia. Semi-arid climates generally ring the desert areas. So maybe a Mediterranean or Middle-Eastern home might be a better model for California. How would that compare to the English-based model of today?
Traditional Mediterranean and Arab cultures both used courtyard houses. Exterior walls in these cultures were often plain or even drab, with much more of the focus being on the interior courtyard. By having a smaller landscaped area and using native plants rather than ones introduced from a wetter climate, a household could cut its water use dramatically. The courtyard house also takes advantage of microclimates, shared walls, shading, and the solar chimney effect to naturally ventilate the house and use less energy than the detached home.
There are many issues facing California: over-development in both the housing and agriculture industries; over-reliance on cars for transportation; and despite their issues, an ever-increasing demand from new residents for housing and services. But one way they can begin to address issues related to water use and sustainability is to adopt a climatically appropriate housing model. Los Angeles isn’t London, so why should it build houses and lawns as if it was?
