Millions In China Live In Energy Efficient Caves

Hugh Pickens writes "Barbara Demick reports in the LA Times that more than 30 million Chinese people live in caves, many of them in Shaanxi province, where the Loess plateau, with its distinctive cliffs of yellow, porous soil, makes digging easy and cave dwelling a reasonable option. The better caves protrude from mountains and are reinforced with brick masonry. Some are connected laterally so a family can have several chambers. Electricity and even running water can be brought in. 'Most aren't so fancy, but I've seen some really beautiful caves: high ceilings and spacious with a nice yard out front where you can exercise and sit in the sun,' says Ren, who works as a driver in the Shaanxi provincial capital, Xian. 'It's cool in the summer and warm in the winter. It's quiet and safe.' In recent years, architects have been reappraising the cave in environmental terms, and they like what they see. 'It is energy efficient. The farmers can save their arable land for planting if they build their houses in the slope. It doesn't take much money or skill to build,' says Liu Jiaping, director of the Green Architecture Research Center in Xian and perhaps the leading expert on cave living. Liu helped design and develop a modernized version of traditional cave dwellings that in 2006 was a finalist for a World Habitat Award, sponsored by a British foundation dedicated to sustainable housing. Meanwhile, a thriving market around Yanan means a cave with three rooms and a bathroom (a total of 750 square feet) can be advertised for sale at $46,000. 'Life is easy and comfortable here. I don't need to climb stairs. I have everything I need,' says 76-year-old Ma Liangshui. 'I've lived all my life in caves, and I can't imagine anything different.'"

      Will advanced civilizations one day find our remains and conclude we were cave dwellers?

      That's already a reasonably common observation in our current civilization (which sometimes characterizes itself as "advanced"). I've seen any number of descriptions of houses as artificial caves. This especially applies to houses made of brick or concrete materials, which are really just artificial stones. If you're living in an area that's mostly flat terrain, making your own mini-hills with a door in the side can be very practical. And we even make "hive" dwelling, which we call apartment building.

      Recently, there have been a number of articles published about the old middle-eastern house construction, that amounts to thick (1 meter or so) outer walls, typically of cheap mud-hay mixtures, covered with a layer of stucco for a harder, waterproof outer shell. The thicker the walls are, the better insulation they provide, and the more stable the internal temperature is. There are old and new "hacienda" style houses in the southwestern US built like this (and fakes that are made with thin stucco-covered walls that don't work nearly as well). It's not unusual for people to observe that this type of house is really an artificial hill constructed around a "cave".

      It's not much of a stretch to call most of our houses "cave dwellings". The difference is mostly a matter of terminology, not function. Pretending that we're "modern" is all well and good, but does somewhat mask the fact that the connections between our dwellings and our ancestors' caves is fairly clear once you get past the pretense that they're something totally different.

      That makes it sound as if cave dwelling was the norm for humans in the Pleistocene. Actually the reason prehistoric people seemed to dwell in caves is because all the above ground structures they resided in disintegrated in short order, which only makes sense when you think about it. Cave dwelling likely was the exception to the rule, given how uncommon suitable caves are in the first place - the loess plateau in China is the largest of its kind in the world, so it's not surprising to see people take advantage of its properties.

      Humans have never been cave dwellers. They just happened to live in caves, too. That we find traces of human settlement in caves is a selection bias -- outside of caves, the evidence has been washed away. It was never a predominant form of settlement.

    why is it that arable land counts for so little in western (at least north american) societies? isn't it a bit of a shame we devote so much land to lawns, rather than something productive? yes, I know: the crops that could be grown are not worth the cost of maintaining them. but why is that? is food too cheap, or labor too expensive? is it a distortion caused by exchange rates?

    I wouldn't mind a part-cave house, especially since a cave would presumably be near some sort of elevation (hillside, escarpment). I think everyone values a bit of a view, some sunlit rooms, etc. but one-story houses on flat plots of land are pretty boring once they scale past a cottage.

      is food too cheap, or labor too expensive

      For many people, I think the calculus goes something like this for, say, growing tomatoes:

      Spend anything from $10-40 per plant in potting soil, pots, cages, seedlings, etc.
      Devote a couple hours of labor, per plant, over the entire growing season to coax them into being productive
      Be inundated with tomatoes for all of three weeks at the height of summer, at the same time when...
      Their grocery store sells tomatoes for $2/lb. all year 'round

      I personally don't take this view. I enjoy my garden, even the modest amount of labor it requires. It's productive enough to do better-than-breakeven on cost, especially when I amortize the upfront costs over many years. Plus, although I wouldn't boast that, say, my tomatoes are world-class, they are a damn sight better than what the grocery store offers. I don't eat much out-of-season, so having fresh tomatoes in January just seems silly.

    Buildings are generally engineered to stay up in earthquakes. The worst earthquake *ever* was in Shaanxi, 1556. It killed over 800,000, because so many people were living in caves (which collapsed). It was estimated to be magnitude 8, about the same size as the 2008 Sichuan quake (which killed about 70,000 people, despite the higher population, and some buildings being badly made).

    With 30 million people living in caves, you don't need a huge proportion to collapse for it to be an unbelievably horrific disaster. It's happened before. It can happen again. And it's no longer the 1500s, when there weren't as many lives at risk, no-one had the knowledge or resources to mitigate against it, peasants were expect to die unnatural deaths anyway. A large quake near Manila might be worse (due to the density, potential for a stronger quake due to it being on a bigger fault, and tsunami potential) but it's it's one of the worst predictable (as in - it could happen, so people should be planning on what to do to prevent too many deaths) disasters that can occur in the world.
