Dogs and Demons   ::   Керр Алекс

Since 1990 more than 70 major dams have fallen across America, and dozens more are scheduled to be dismantled. Meanwhile, Japan's Construction Ministry plans to add 500 new dams to the more than 2,800 that have already been built.

To see at close hand how the construction frenzy affects one small mountain village, let us take a short journey to Iya Valley, a picturesque fastness of canyons and peaks in the center of the southern island of Shikoku. When I bought an old thatch-roofed farmhouse in Iya in 1971, people considered this region so remote that they called it the Tibet of Japan. Villa gers subsisted on crops such as buckwheat and tobacco, as well as forestry.

Over the next twenty-five years, young people fled Iya for the prosperous cities, and local agriculture collapsed. With its dramatic landscape and a romantic history going back to the civil wars of the twelfth century, Iya had a golden opportunity to revive its local economy with tourism and resorts in the 1980s. Yet in a pattern that repeats itself in countless regions across Japan, Iya failed to develop this potential. The reason was that the village suddenly found itself awash with cash: money that flowed from building dams and roads, paid for by a national policy to prop up rural economies by subsidizing civil-engineering works. Beginning in the 1960s, a tidal wave of construction money crashed over Iya, sweeping away every other industry. By 1997, my neighbors had all become construction workers.

Most foreigners and even many Japanese harbor a pleasing fantasy of life in the Japanese village. While driving past quaint farmhouses or perusing lovely photographs of rice paddies, it's tempting to imagine what bucolic country life must be: oneness with the seasons, the yearly round of planting and harvesting, and so forth. However, when you actually live in the countryside you soon learn that the uniform of the Japanese farmer is no longer a straw raincoat and a hoe but a hard hat and a cement shovel. In 1972, for example, my neighbor Mrs. Ото farmed tea, potatoes, corn, cucumbers, and mulberry for silkworms. In 2000, her fields lie fallow as she dons her hard hat every day to commute by van to construction sites, where her job is to scrape aluminum molds for concrete used to build retaining walls. In Iya Valley, it makes no sense to ask someone, «What line of work are you in?» Everyone lives off doboku, « construction.»

More than 90 percent of all the money flowing into Iya now comes from road- and dam-building projects funded by the Construction, Transport, and Agriculture ministries. This means that no environmental initiative can possibly make headway, for

Iya has become addicted to dams and roads. Stop building them, and Mrs. Ото and most of the other villagers are out of work. Without the daily pouring of concrete, the village dies.

The most remarkable paradox is that Iya doesn't need these roads and dams; it builds them only because it must spend the construction subsidies or lose the money. After decades of building to no particular purpose, the legacy is visible everywhere, with hardly a single hillside standing free of giant slabs of cement built to prevent «landslide damage,» even though many of these are located miles from any human habitation. Forestry roads honeycomb the mountains, though the forestry industry collapsed thirty years ago. Concrete embankments line Iya River and most of its tributaries, whose beds run dry a large part of the year because of the numerous dams siphoning water to electric power plants. The future? Although traffic is so sparse in Iya that in some places spiderwebs grow across the roads, the prefectural government devoted the 1990s to blasting a highway right through the cliffs lining the upper half of the valley, concreting over the few scenic corners that are left.

If this is what happened to the «Tibet of Japan,» one can well imagine the fate that has befallen more accessible rural areas. To support the construction industry, the government annually pours hundreds of billions of dollars into civil-engineering projects-dams, seashore- and river-erosion control, flood control, road building, and the like. Dozens of government agencies owe their existence solely to thinking up new ways of sculpting the earth. Planned spending on public works for the decade 1995-2005 will come to an astronomical ¥630 trillion (about $6.2 trillion), three to four times more than what the United States, with twenty times the land area and more than double the population, will spend on public construction in the same period. In this respect, Japan has become a huge social-welfare state, channeling hundreds of billions of dollars through public works to low-skilled workers every year.

It is not only the rivers and valleys that have suffered. The seaside reveals the greatest tragedy: by 1993, 55 percent of the entire coast of Japan had been lined with cement slabs and giant concrete tetrapods. An article in a December 1994 issue of the popular weekly Shukan Post illustrated a ravaged coastline in Okinawa, commenting, «The seashore has hardened into concrete, and the scenery of unending gray tetrapods piled on top of one another is what you can see everywhere in Japan. It has changed into something irritating and ordinary. When you look at this seashore, you can't tell whether it is the coast of Shonan, the coast of Chiba, or the coast of Okinawa.»

Tetrapods may be an unfamiliar word to readers who have not visited Japan and seen them lined up by the hundreds along bays and beaches. They look like oversize jacks with four concrete legs, some weighing as much as fifty tons. Tetrapods, which are supposed to retard beach erosion, are big business. So profitable are they to bureaucrats that three different ministries – of Transport, of Agriculture, Forestry, and Fisheries, and of Construction – annually spend ¥500 billion each, sprinkling tetrapods along the coast, like three giants throwing jacks, with the shore as their playing board. These projects are mostly unnecessary or worse than unnecessary. It turns out that wave action on tetrapods wears the sand away faster and causes greater erosion than would be the case if the beaches had been left alone.

It took some decades for this lesson to sink in, but in the 1980s American states, beginning with Maine, began one by one to prohibit the hard stabilization of the shoreline; in 1988, South Carolina mandated not only a halt to new construction but removal of all existing armoring within forty years. In Japan, however, armoring of the seacoasts is increasing.
