We are adding 73m mouths a year. The global population will grow from 6.5bn to 9.5bn before peaking near mid-century.
Asia’s bourgeoisie is switching to an animal-based diet. If they follow the Japanese, protein-intake will rise by nine times. It takes 8.3 grams of corn feed to produce a 1g of beef, or 3.1g for pork.
China’s meat demand has risen to 50kg per capita from 20kg in 1980, but this has been gradual. The FAO insists that this dietary shift is “not the cause of the sudden food price spike that began in 2005″.

Is there any more land? Yes, in Russia, Ukraine, and Kazakhstan, where acreage planted has fallen 12pc since Soviet days. Existing grain yields are 2.4 tonnes per hectare in Ukraine, 1.8 in Russia, and 1.11 in Kazakhstan, com-pared with 6.39 in the US. Investment would do wonders here. But the structure is chaotic.
Brazil has the world’s biggest reserves of “potential arable land” with 483m hectares (it currently cultivates 67m), and Colombia has 62m – both offering biannual harvests.

Food export controls have been imposed by Russia, China, India, Vietnam, Argentina, and Serbia. We are disturbingly close to a chain reaction that could shatter our assumptions about food security.
The Philippines – a country with ample foreign reserves of $36bn (Britain has $27bn) – last week had to enlist its embassies to hunt for grain supplies after China withheld shipments. Washington stepped in, pledging “absolutely” to cover Philippine grain needs. A new Cold War is taking shape, around energy and food.
The world intelligentsia has been asleep at the wheel. While we rage over global warming, global hunger has swept in under the radar screen.
