KEEPING ITS HEAD ABOVE WATER
New Orleans faces doomsday scenario

New Orleans is sinking.
And its main buffer from a hurricane, the protective Mississippi River delta, is quickly eroding away, leaving the historic city perilously close to disaster.
So vulnerable, in fact, that earlier this year the Federal Emergency Management Agency ranked the potential damage to New Orleans as among the three likeliest, most castastrophic disasters facing this country.
The other two? A massive earthquake in San Francisco, and, almost prophetically, a terrorist attack on New York City.
The New Orleans hurricane scenario may be the deadliest of all.
In the face of an approaching storm, scientists say, the city's less-than-adequate evacuation routes would strand 250,000 people or more, and probably kill one of 10 left behind as the city drowned under 20 feet of water. Thousands of refugees could land in Houston.
Economically, the toll would be shattering.
Southern Louisiana produces one-third of the country's seafood, one-fifth of its oil and one-quarter of its natural gas. The city's tourism, lifeblood of the French Quarter, would cease to exist. The Big Easy might never recover.
And, given New Orleans' precarious perch, some academics wonder if it should be rebuilt at all.
It's been 36 years since Hurricane Betsy buried New Orleans 8 feet deep. Since then a deteriorating ecosystem and increased development have left the city in an ever more precarious position. Yet the problem went unaddressed for decades by a laissez-faire government, experts said.
"To some extent, I think we've been lulled to sleep," said Marc Levitan, director of Louisiana State University's hurricane center.
Hurricane season ended Friday, and for the second straight year no hurricanes hit the United States. But the season nonetheless continued a long-term trend of more active seasons, forecasters said. Tropical Storm Allison became this country's most destructive tropical storm ever.
Yet despite the damage Allison wrought upon Houston, dropping more than 3 feet of water in some areas, a few days later much of the city returned to normal as bloated bayous drained into the Gulf of Mexico.
The same storm dumped a mere 5 inches on New Orleans, nearly overwhelming the city's pump system. If an Allison-type storm were to strike New Orleans, or a Category 3 storm or greater with at least 111 mph winds, the results would be cataclysmic, New Orleans planners said.
"Any significant water that comes into this city is a dangerous threat," Walter Maestri, Jefferson Parish emergency management director, told Scientific American for an October article.
"Even though I have to plan for it, I don't even want to think about the loss of life a huge hurricane would cause."
New Orleans is essentially a bowl ringed by levees that protect the city from the Mississippi River to its south and Lake Pontchartrain to the north. The bottom of the bowl is 14 feet below sea level, and efforts to keep it dry are only digging a deeper hole.
During routine rainfalls the city's dozens of pumps push water uphill into the lake. This, in turn, draws water from the ground, further drying the ground and sinking it deeper, a problem known as subsidence.
This problem also faces Houston as water wells have sucked the ground dry. Houston's solution is a plan to convert to surface drinking water. For New Orleans, eliminating pumping during a rainfall is not an option, so the city continues to sink.
A big storm, scientists said, would likely block four of five evacuation routes long before it hit. Those left behind would have no power or transportation, and little food or medicine, and no prospects for a return to normal any time soon.
"The bowl would be full," Levitan said. "There's simply no place for the water to drain."
Estimates for pumping the city dry after a huge storm vary from six to 16 weeks. Hundreds of thousands would be homeless, their residences destroyed.
The only solution, scientists, politicians and other Louisiana officials agree, is to take large-scale steps to minimize the risks, such as rebuilding the protective delta.
Every two miles of marsh between New Orleans and the Gulf reduces a storm surge -- which in some cases is 20 feet or higher -- by half a foot.
In 1990, the Breaux Act, named for its author, Sen. John Breaux, D-La., created a task force of several federal agencies to address the severe wetlands loss in coastal Louisiana. The act has brought about $40 million a year for wetland restoration projects, but it hasn't been enough.
"It's kind of been like trying to give aspirin to a cancer patient," said Len Bahr, director of Louisiana Gov. Mike Foster's coastal activities office.
The state loses about 25 square miles of land a year, the equivalent of about one football field every 15 minutes. The fishing industry, without marshes, swamps and fertile wetlands, could lose a projected $37 billion by the year 2050.
University of New Orleans researchers studied the impact of Breaux Act projects on the vanishing wetlands and estimated that only 2 percent of the loss has been averted. Clearly, Bahr said, there is a need for something much bigger. There is some evidence this finally may be happening.
A consortium of local, state and federal agencies is studying a $2 billion to $3 billion plan to divert sediment from the Mississippi River back into the delta. Because the river is leveed all the way to the Gulf, where sediment is dumped into deep water, nothing is left to replenish the receding delta.
Other possible projects include restoration of barrier reefs and perhaps a large gate to prevent Lake Pontchartrain from overflowing and drowning the city.
All are multibillion-dollar projects. A plan to restore the Florida Everglades attracted $4 billion in federal funding, but the state had to match it dollar for dollar. In Louisiana, so far, there's only been a willingness to match 15 or 25 cents.
"Our state still looks for a 100 percent federal bailout, but that's just not going to happen," said University of New Orleans geologist Shea Penland, a delta expert.
"We have an image and credibility problem. We have to convince our country that they need to take us seriously, that they can trust us to do a science-based restoration program."

New Orleans: A Geopolitical Prize
By George Friedman
The American political system was founded in Philadelphia, but the American nation was built on the vast farmlands that stretch from the Alleghenies to the Rockies. That farmland produced the wealth that funded American industrialization: It permitted the formation of a class of small landholders who, amazingly, could produce more than they could consume. They could sell their excess crops in the east and in Europe and save that money, which eventually became the founding capital of American industry.
But it was not the extraordinary land nor the farmers and ranchers who alone set the process in motion. Rather, it was geography -- the extraordinary system of rivers that flowed through the Midwest and allowed them to ship their surplus to the rest of the world. All of the rivers flowed into one -- the Mississippi -- and the Mississippi flowed to the ports in and around one city: New Orleans. It was in New Orleans that the barges from upstream were unloaded and their cargos stored, sold and reloaded on ocean-going vessels. Until last Sunday, New Orleans was, in many ways, the pivot of the American economy.
For that reason, the Battle of New Orleans in January 1815 was a key moment in American history. Even though the battle occurred after the War of 1812 was over, had the British taken New Orleans, we suspect they wouldn't have given it back. Without New Orleans, the entire Louisiana Purchase would have been valueless to the United States. Or, to state it more precisely, the British would control the region because, at the end of the day, the value of the Purchase was the land and the rivers - which all converged on the Mississippi and the ultimate port of New Orleans. The hero of the battle was Andrew Jackson, and when he became president, his obsession with Texas had much to do with keeping the Mexicans away from New Orleans.
During the Cold War, a macabre topic of discussion among bored graduate students who studied such things was this: If the Soviets could destroy one city with a large nuclear device, which would it be? The usual answers were Washington or New York. For me, the answer was simple: New Orleans. If the Mississippi River was shut to traffic, then the foundations of the economy would be shattered. The industrial minerals needed in the factories wouldn't come in, and the agricultural wealth wouldn't flow out. Alternative routes really weren't available. The Germans knew it too: A U-boat campaign occurred near the mouth of the Mississippi during World War II. Both the Germans and Stratfor have stood with Andy Jackson: New Orleans was the prize.
Last Sunday, nature took out New Orleans almost as surely as a nuclear strike. Hurricane Katrina's geopolitical effect was not, in many ways, distinguishable from a mushroom cloud. The key exit from North America was closed. The petrochemical industry, which has become an added value to the region since Jackson's days, was at risk. The navigability of the Mississippi south of New Orleans was a question mark. New Orleans as a city and as a port complex had ceased to exist, and it was not clear that it could recover.
The Ports of South Louisiana and New Orleans, which run north and south of the city, are as important today as at any point during the history of the republic. On its own merit, POSL is the largest port in the United States by tonnage and the fifth-largest in the world. It exports more than 52 million tons a year, of which more than half are agricultural products -- corn, soybeans and so on. A large proportion of U.S. agriculture flows out of the port. Almost as much cargo, nearly 17 million tons, comes in through the port -- including not only crude oil, but chemicals and fertilizers, coal, concrete and so on.
A simple way to think about the New Orleans port complex is that it is where the bulk commodities of agriculture go out to the world and the bulk commodities of industrialism come in. The commodity chain of the global food industry starts here, as does that of American industrialism. If these facilities are gone, more than the price of goods shifts: The very physical structure of the global economy would have to be reshaped. Consider the impact to the U.S. auto industry if steel doesn't come up the river, or the effect on global food supplies if U.S. corn and soybeans don't get to the markets.
The problem is that there are no good shipping alternatives. River transport is cheap, and most of the commodities we are discussing have low value-to-weight ratios. The U.S. transport system was built on the assumption that these commodities would travel to and from New Orleans by barge, where they would be loaded on ships or offloaded. Apart from port capacity elsewhere in the United States, there aren't enough trucks or rail cars to handle the long-distance hauling of these enormous quantities -- assuming for the moment that the economics could be managed, which they can't be.
The focus in the media has been on the oil industry in Louisiana and Mississippi. This is not a trivial question, but in a certain sense, it is dwarfed by the shipping issue. First, Louisiana is the source of about 15 percent of U.S.-produced petroleum, much of it from the Gulf. The local refineries are critical to American infrastructure. Were all of these facilities to be lost, the effect on the price of oil worldwide would be extraordinarily painful. If the river itself became unnavigable or if the ports are no longer functioning, however, the impact to the wider economy would be significantly more severe. In a sense, there is more flexibility in oil than in the physical transport of these other commodities.
There is clearly good news as information comes in. By all accounts, the Louisiana Offshore Oil Port, which services supertankers in the Gulf, is intact. Port Fourchon, which is the center of extraction operations in the Gulf, has sustained damage but is recoverable. The status of the oil platforms is unclear and it is not known what the underwater systems look like, but on the surface, the damage - though not trivial -- is manageable.
The news on the river is also far better than would have been expected on Sunday. The river has not changed its course. No major levees containing the river have burst. The Mississippi apparently has not silted up to such an extent that massive dredging would be required to render it navigable. Even the port facilities, although apparently damaged in many places and destroyed in few, are still there. The river, as transport corridor, has not been lost.
What has been lost is the city of New Orleans and many of the residential suburban areas around it. The population has fled, leaving behind a relatively small number of people in desperate straits. Some are dead, others are dying, and the magnitude of the situation dwarfs the resources required to ameliorate their condition. But it is not the population that is trapped in New Orleans that is of geopolitical significance: It is the population that has left and has nowhere to return to.
The oil fields, pipelines and ports required a skilled workforce in order to operate. That workforce requires homes. They require stores to buy food and other supplies. Hospitals and doctors. Schools for their children. In other words, in order to operate the facilities critical to the United States, you need a workforce to do it -- and that workforce is gone. Unlike in other disasters, that workforce cannot return to the region because they have no place to live. New Orleans is gone, and the metropolitan area surrounding New Orleans is either gone or so badly damaged that it will not be inhabitable for a long time.
It is possible to jury-rig around this problem for a short time. But the fact is that those who have left the area have gone to live with relatives and friends. Those who had the ability to leave also had networks of relationships and resources to manage their exile. But those resources are not infinite -- and as it becomes apparent that these people will not be returning to New Orleans any time soon, they will be enrolling their children in new schools, finding new jobs, finding new accommodations. If they have any insurance money coming, they will collect it. If they have none, then -- whatever emotional connections they may have to their home -- their economic connection to it has been severed. In a very short time, these people will be making decisions that will start to reshape population and workforce patterns in the region.
A city is a complex and ongoing process - one that requires physical infrastructure to support the people who live in it and people to operate that physical infrastructure. We don't simply mean power plants or sewage treatment facilities, although they are critical. Someone has to be able to sell a bottle of milk or a new shirt. Someone has to be able to repair a car or do surgery. And the people who do those things, along with the infrastructure that supports them, are gone -- and they are not coming back anytime soon.
It is in this sense, then, that it seems almost as if a nuclear weapon went off in New Orleans. The people mostly have fled rather than died, but they are gone. Not all of the facilities are destroyed, but most are. It appears to us that New Orleans and its environs have passed the point of recoverability. The area can recover, to be sure, but only with the commitment of massive resources from outside -- and those resources would always be at risk to another Katrina.
The displacement of population is the crisis that New Orleans faces. It is also a national crisis, because the largest port in the United States cannot function without a city around it. The physical and business processes of a port cannot occur in a ghost town, and right now, that is what New Orleans is. It is not about the facilities, and it is not about the oil. It is about the loss of a city's population and the paralysis of the largest port in the United States.
Let's go back to the beginning. The United States historically has depended on the Mississippi and its tributaries for transport. Barges navigate the river. Ships go on the ocean. The barges must offload to the ships and vice versa. There must be a facility to empower this exchange. It is also the facility where goods are stored in transit. Without this port, the river can't be used. Protecting that port has been, from the time of the Louisiana Purchase, a fundamental national security issue for the United States.
Katrina has taken out the port -- not by destroying the facilities, but by rendering the area uninhabited and potentially uninhabitable. That means that even if the Mississippi remains navigable, the absence of a port near the mouth of the river makes the Mississippi enormously less useful than it was. For these reasons, the United States has lost not only its biggest port complex, but also the utility of its river transport system -- the foundation of the entire American transport system. There are some substitutes, but none with sufficient capacity to solve the problem.
It follows from this that the port will have to be revived and, one would assume, the city as well. The ports around New Orleans are located as far north as they can be and still be accessed by ocean-going vessels. The need for ships to be able to pass each other in the waterways, which narrow to the north, adds to the problem. Besides, the Highway 190 bridge in Baton Rouge blocks the river going north. New Orleans is where it is for a reason: The United States needs a city right there.
New Orleans is not optional for the United States' commercial infrastructure. It is a terrible place for a city to be located, but exactly the place where a city must exist. With that as a given, a city will return there because the alternatives are too devastating. The harvest is coming, and that means that the port will have to be opened soon. As in Iraq, premiums will be paid to people prepared to endure the hardships of working in New Orleans. But in the end, the city will return because it has to.
Geopolitics is the stuff of permanent geographical realities and the way they interact with political life. Geopolitics created New Orleans. Geopolitics caused American presidents to obsess over its safety. And geopolitics will force the city's resurrection, even if it is in the worst imaginable place.
