Tom Philpott at Grist has a review of Paul Roberts' new book "The End Of Food" - The Locavore's Dilemma.

In the Middle East, water-poor nations are using petrol profits to buy farmland in economically depressed countries like Pakistan and Sudan. China, with its own farmland under pressure from development and pollution, is using some of its vast export income to snap up land in Africa and Southeast Asia.

Meanwhile, Brazil -- the globe's emerging agricultural powerhouse and an increasingly important food supplier to China -- recently threatened to nationalize its fertilizer deposits. Such a move would rankle huge U.S. grain-trading firms like Cargill and Bunge, which dominate Brazil's ever-expanding fertilizer market.

In other words, food production is rapidly emerging as a key geopolitical issue. As food prices rise along with oil futures and climate change looks set to disrupt global agriculture patterns, we can expect more of the same. Indeed, hardheaded investors -- the kind who made a killing earlier this decade snapping up oil futures -- are increasingly playing the food-as-geopolitics angle. "Big private investors are starting to make bolder and longer-term bets that the world's need for food will greatly increase -- by buying farmland, fertilizer, grain elevators and shipping equipment," The New York Times recently reported.

If food is the new oil, then we're lucky that the ace geopolitical reporter Paul Roberts has turned his attention to the dinner table. His 2004 book The End of Oil crystallized the perils surrounding humanity's reliance on fossil energy. Crude oil prices have doubled and doubled again since Roberts wrote that book, yet it remains a valuable and even timely resource.

Now he's attempted a similar feat with our globe-spanning industrial food system. His new book The End of Food is the kind of work you wish policy makers and presidential candidates were grappling with, but you're pretty sure they're not. It also deserves to be read by food-justice activists, locavores, and other critics of industrial food.

National Geographic has a new article on peak oil, this time from Paul Roberts, called Tapped Out - "World oil demand is surging as supplies approach their limits". NGM has been a longtime follower of the issue over the years, with past features like The End Of Cheap Oil.

The same issue also has a look at Siberian oil and a look at When will the peak hit ?.

In 2000 a Saudi oil geologist named Sadad I. Al Husseini made a startling discovery. Husseini, then head of exploration and production for the state-owned oil company, Saudi Aramco, had long been skeptical of the oil industry's upbeat forecasts for future production. Since the mid-1990s he had been studying data from the 250 or so major oil fields that produce most of the world's oil. He looked at how much crude remained in each one and how rapidly it was being depleted, then added all the new fields that oil companies hoped to bring on line in coming decades. When he tallied the numbers, Husseini says he realized that many oil experts "were either misreading the global reserves and oil-production data or obfuscating it."

Where mainstream forecasts showed output rising steadily each year in a great upward curve that kept up with global demand, Husseini's calculations showed output leveling off, starting as early as 2004. Just as alarming, this production plateau would last 15 years at best, after which the output of conventional oil would begin "a gradual but irreversible decline."

That is hardly the kind of scenario we've come to expect from Saudi Aramco, which sits atop the world's largest proven oil reserves—some 260 billion barrels, or roughly a fifth of the world's known crude—and routinely claims that oil will remain plentiful for many more decades. Indeed, according to an industry source, Saudi oil minister Ali al-Naimi took a dim view of Husseini's report, and in 2004 Husseini retired from Aramco to become an industry consultant. But if he is right, a dramatic shift lies just ahead for a world whose critical systems, from defense to transportation to food production, all run on cheap, abundant oil.
