Threats Rising Due To Climate Change
By Michael Kimmelman, New York Times
With climate change, the Java Sea is rising and weather here is becoming more extreme. Earlier this month another freakish storm briefly turned Jakarta’s streets into rivers and brought this vast area of nearly 30 million residents to a virtual halt.
One local climate researcher, Irvan Pulungan, an adviser to the city’s governor, fears that temperatures may rise several degrees Fahrenheit, and the sea level as much as three feet in the region, over the coming century. That, alone, spells potential disaster for this teeming metropolis.
But global warming turned out not to be the only culprit behind the historic floods that overran Rasdiono’s bodega and much of the rest of Jakarta in 2007. The problem, it turned out, was that the city itself is sinking.
In fact, Jakarta is sinking faster than any other big city on the planet, faster, even, than climate change is causing the sea to rise — so surreally fast that rivers sometimes flow upstream, ordinary rains regularly swamp neighborhoods and buildings slowly disappear underground, swallowed by the earth. The main cause: Jakartans are digging illegal wells, drip by drip draining the underground aquifers on which the city rests — like deflating a giant cushion underneath it. About 40 percent of Jakarta now lies below sea level.
Coastal districts, like Muara Baru, near the Blessed Bodega, have sunk as much as 14 feet in recent years. Not long ago I drove around northern Jakarta and saw teenagers fishing in the abandoned shell of a half-submerged factory. The banks of a murky canal lapped at the trestle of a railway bridge, which, until recently, had arched high over it.
Climate change acts here as it does elsewhere, exacerbating scores of other ills. And in Jakarta’s case, a tsunami of human-made troubles — runaway development, a near-total lack of planning, next to no sewers and only a limited network of reliable, piped-in drinking water — poses an imminent threat to the city’s survival.
Sinking buildings, sprawl, polluted air and some of the worst traffic jams in the world are symptoms of other deeply rooted troubles. Distrust of government is a national condition. Conflicts between Islamic extremists and secular Indonesians, Muslims and ethnic Chinese have blocked progress, helped bring down reform-minded leaders and complicated everything that happens here, or doesn’t happen, to stop the city from sinking.
“Nobody here believes in the greater good, because there is so much corruption, so much posturing about serving the public when what gets done only serves private interests,” as Sidney Jones, the director of the local Institute for Policy Analysis of Conflict, put it. “There is no trust.”
Hydrologists say the city has only a decade to halt its sinking. If it can’t, northern Jakarta, with its millions of residents, will end up underwater, along with much of the nation’s economy. Eventually, barring wholesale change and an infrastructural revolution, Jakarta won’t be able to build walls high enough to hold back the rivers, canals and the rising Java Sea.
And even then, of course, if it does manage to heal its self-inflicted wounds, it still has to cope with all the mounting threats from climate change.
As far the eye can see, 21st-century Jakarta is a smoggy tangle of freeways and skyscrapers. Spread along the northwestern coast of Java, this capital of the nation with the world’s largest Muslim population used to be a soggy, bug-infested trading port for the Hindu kingdom of Sunda before local sultans took it over in 1527.
Dutch colonists arrived a century later, establishing a base for the East India territories. Imagining a tropical Amsterdam, they laid out streets and canals to try to cope with water pouring in from the south, out of the forests and mountains, where rain falls nearly 300 days out of the year. Thirteen rivers feed into the city.
After independence in 1945, the city began to sprawl. Today, it is virtually impossible to walk around. Parks are rarer than Javan rhinos. A trip to the nearest botanical garden requires the better part of a day in bumper-to-bumper traffic.
“Living here, we don’t have other places to go,” said Yudi and Titi, a young professional couple who one recent Sunday had made the roughly hour’s round trip from western Jakarta to the center of the city just to spend a few minutes walking up and down a chaotic, multi-lane freeway briefly closed to traffic. “Without cars, at least you can breathe for a few minutes,” Titi said.
The most urgent problems are in North Jakarta, a coastal mash-up of ports, nautically themed high-rises, aged fish markets, abject slums, power plants, giant air-conditioned malls and the congested remnants of the colonial Dutch settlement, with its decrepit squares and streets of crumbling warehouses and dusty museums.
Some of the world’s most polluted canals and rivers weave a spider’s web through the area.
It is where the city is sinking fastest.
That’s because, after decades of reckless growth and negligent leadership, crises have lined up here like dominoes.
Jakarta’s developers and others illegally dig untold numbers of wells because water is piped to less than half the population at what published reports say are extortionate costs by private companies awarded government concessions.
The aquifers aren’t being replenished, despite heavy rains and the abundance of rivers, because more than 97 percent of Jakarta is now smothered by concrete and asphalt. Open fields that once absorbed rain have been paved over. Shores of mangroves that used to help relieve swollen rivers and canals during monsoons have been overtaken by shantytowns and apartment towers.
There is always tension between immediate needs and long-term plans. It’s a similar story in other sinking giants like Mexico City. Here, all of the construction, combined with the draining of the aquifers, is causing the rock and sediment on which Jakarta rests to pancake.
