Resilience to Earthquakes

In response to the high number of school children killed in school collapses in the recent Sichuan earthquake, Andrew Revkin writes in the New York Times about the challenges of enhancing resilience - even when the problem and solution are well understood - in his article A Move to Turn Schools From Earthquake Death Traps Into Havens:

… The main challenge in bolstering resilience to such geophysical shocks, Ms. Wang, Mr. Tucker and many other experts said, is not the structural engineering. There is no mystery to adding and securing iron rods in concrete, securing floors to beams, boosting the resilience of columns, monitoring the size of gravel mixed with cement.

It is not cost, either. In California, Dr. Tucker notes, the premium for building earthquake resistance into new schools is less than 4 percent. The payoff, beyond saved lives, is significantly lower repair costs after a temblor — 10 to 100 times less than in unimproved buildings. (In poorer countries, the differential in cost could be substantially higher, other experts note, but the payoff, they say, is priceless.)

Rich or poor, the big challenge lies in overcoming social and political hurdles that still give priority to pressing daily problems over foreseeable disasters that may not occur for decades, scores of years, or longer. In some developing countries there is a tendency to ascribe earthquakes and their consequences to fate, but Dr. Tucker and other experts say that lets the authorities off the hook.

“I can’t hold a government responsible for protecting its citizens against a meteorite falling out of the sky,” Dr. Tucker said. “But I can and do hold a government in a country with known seismic risk responsible for protecting its children, who are compelled to attend school, from the school collapsing during an earthquake.”

Dr. Tucker has written or co-written a lengthening string of reports pointing to the building risks worldwide as more populations shift to urban areas, often into shoddy, hastily built structures, with children sent to schools in similar, and often worse, condition.

Arthur Lerner-Lam, who maps disaster risks at Columbia University’s Lamont-Doherty Earth Observatory, agrees that urbanization in earthquake zones is setting the world up for its first true megadisaster — a million-casualty earthquake that many seismologists say is only a matter of time. The greatest risk, he said, lies in a belt from Italy and Turkey through central Asia and the Himalayas into central China.

In such regions, Dr. Tucker said, the best blueprints and materials are no guarantee of safety without adequate building codes, laws, training, inspections and enforcement.

The biggest challenge of all may simply be redefining security, and building societies that demand that government investments match risks, said Fouad Bendimerad, an engineering and risk-management consultant in California and chairman of the Earthquakes and Megacities Initiative.

“The typical government spends around 15 percent of its G.D.P. to defend against exterior military threats that may never occur during the lifetime of generation,” Dr. Bendimerad said. “Why do we want to exonerate governments from dedicating a small portion of that 15 percent to protect against the threats of natural hazards that we know will happen?”

Ecological Economics of the Global Food Trade

From the April 26th New York Times, Environmental Cost of Shipping Groceries Around the World, discusses the complexities of global food trade. Its great efficiency, the hidden subsidies to transport, and the politics of carbon footprint calculations:

Cod caught off Norway is shipped to China to be turned into filets, then shipped back to Norway for sale. Argentine lemons fill supermarket shelves on the Citrus Coast of Spain, as local lemons rot on the ground. Half of Europe’s peas are grown and packaged in Kenya. …

Increasingly efficient global transport networks make it practical to bring food before it spoils from distant places where labor costs are lower. And the penetration of mega-markets in nations from China to Mexico with supply and distribution chains that gird the globe — like Wal-Mart, Carrefour and Tesco — has accelerated the trend.

But the movable feast comes at a cost: pollution — especially carbon dioxide, the main global warming gas — from transporting the food.

Under longstanding trade agreements, fuel for international freight carried by sea and air is not taxed. Now, many economists, environmental advocates and politicians say it is time to make shippers and shoppers pay for the pollution, through taxes or other measures. …

Some of those companies say that they are working to limit greenhouse gases produced by their businesses but that the question is how to do it. They oppose regulation and new taxes and, partly in an effort to head them off, are advocating consumer education instead.

Tesco, for instance, is introducing a labeling system that will let consumers assess a product’s carbon footprint.

Some foods that travel long distances may actually have an environmental advantage over local products, like flowers grown in the tropics instead of in energy-hungry European greenhouses.

“This may be as radical for environmental consuming as putting a calorie count on the side of packages to help people who want to lose weight,” a spokesman for Tesco, Trevor Datson, said. …

Some studies have calculated that as little as 3 percent of emissions from the food sector are caused by transportation. But Mr. Watkiss, the Oxford economist, said the percentage was growing rapidly. Moreover, imported foods generate more emissions than generally acknowledged because they require layers of packaging and, in the case of perishable food, refrigeration. …

The problem is measuring the emissions. The fact that food travels farther does not necessarily mean more energy is used. Some studies have shown that shipping fresh apples, onions and lamb from New Zealand might produce lower emissions than producing the goods in Europe, where — for example — storing apples for months would require refrigeration.

But those studies were done in New Zealand, and the food travel debate is inevitably intertwined with economic interests.

Fish Piracy Feeds the Global Rich

A New York Times article Europe’s Appetite for Seafood Propels Illegal Trade describes how fisheries collapse is leading roving bandits to scoop up the world’s valuable fish leaving little behind for local fishers:

Fish is now the most traded animal commodity on the planet, with about 100 million tons of wild and farmed fish sold each year. Europe has suddenly become the world’s largest market for fish, worth more than 14 billion euros, or about $22 billion a year. Europe’s appetite has grown as its native fish stocks have shrunk so that Europe now needs to import 60 percent of fish sold in the region, according to the European Union.

In Europe, the imbalance between supply and demand has led to a thriving illegal trade. Some 50 percent of the fish sold in the European Union originates in developing nations, and much of it is laundered like contraband, caught and shipped illegally beyond the limits of government quotas or treaties. The smuggling operation is well financed and sophisticated, carried out by large-scale mechanized fishing fleets able to sweep up more fish than ever, chasing threatened stocks from ocean to ocean.
