One well-known project was a canal 1,400 km long across the drought-plagued Yellow Earth Plateau in the northwest. It had to cross 800 mountains and valleys and the 170,000 laborers had to dig caves to sleep in, and forage for herbs to eke out their meager food. Months into the project, tunnels which they had already started digging, by hand, were abandoned in favor of culverts. After more months, this approach in turn was abandoned, and some of the tunnels reinstated. The project went on in this way for three years, during which at least 2,000 laborers died, and was then abandoned. The official account admitted that not one plot of land had benefited.
Most of the projects turned out to be a stupendous waste. Many had to be abandoned halfway: out of the over 500 large reservoirs (100 million cubic meters capacity or more), 200 had already been abandoned by late 1959. Many others collapsed during Mao’s lifetime. The worst dam disaster in human history happened in 1975 in Mao’s model province of Henan, when scores of reservoirs built during the Leap crumbled in a storm, drowning an estimated 230,000–240,000 people (official death toll: 85,600). Other Mao-era follies went on killing people long after his death, and as of 1999, no fewer than 33,000 were considered a risk to human life. The dams also uprooted untold millions from their homes, and more than two decades later there were still 10.2 million “reservoir displaced persons.”
MAO INFLICTED MANY other half-baked schemes on the peasants, like forcing them to dig up soil by hand to a depth of half a meter. “Use the human wave tactic, and turn every field over,” he ordered. Grossly excessive close planting was another. Close planting needed fertilizer, but Mao refused the requisite investments, and in late 1958 he actually ordered: “Reduce chemical fertiliser imports.” On another occasion he said: “Turn China into a country of pigs … so there will be lots of manure … and more than enough meat, which can be exported in exchange for iron and steel.” But he did not say where the feed was to come from for these pigs. In fact, under Mao’s stewardship the number of pigs fell by no less than 48 percent between 1957 and 1961.
Over the centuries, Chinese peasants had applied their ingenuity to find every possible substance that could be used as fertilizer. In urban areas, every spot where human waste was dumped was allocated to a particular village, and peasants coming in before dawn to collect this waste with their special oblong barrels on carts were a feature of life. Human waste was so precious that frequent fights broke out between people from different villages over poaching, using their long-handled ladles. Desperate to find new sources for fertilizer, people started to mix human and animal manure with the thatched roofs and earth walls of old houses, into which smoke and grease had seeped. Millions of peasant houses were torn down to feed into manure pits, known as “shit lakes and piss seas.”
One day it hit Mao that a good way to keep food safe would be to get rid of sparrows, as they ate grain. He designated sparrows as one of “Four Pests” to be eliminated, along with rats, mosquitoes and flies, and mobilized the entire population to wave sticks and brooms and make a giant din to scare sparrows off landing so that they would fall from fatigue and be caught and killed by the crowds. There was much to be said for eradicating the other three, which were genuine pests, though one side-effect was that whatever slight privacy people had once had in performing their bodily functions disappeared, as eager fly-collectors loitered in droves at public lavatories. But the case for eliminating sparrows was not so clear-cut, as sparrows got rid of many pests, as well as eating grain — and, needless to say, many other birds died in the killing spree. Pests once kept down by sparrows and other birds now flourished, with catastrophic results. Pleas from scientists that the ecological balance would be upset were ignored.
It was not long before a request from the Chinese government marked “Top Secret” reached the Soviet embassy in Peking. In the name of socialist internationalism, it read, please send us 200,000 sparrows from the Soviet Far East as soon as possible. Mao had to accept that his anti-sparrow drive was counter-productive, and it gradually petered out.
The “Four Pests” campaign was a sort of Maoist DIY substitute for a health service, as it was labor-intensive and investment-free. Mao had wanted to get rid of dogs, which consumed food, but relented, when he was advised that peasants needed them to guard their houses when they were out at work.
