The Birds And The Bees (And The Humans, Too)

Ambrose Evans-Pritchard makes the connection between world food shortages and the collapse of the world's honeybee population, something I hadn't even considered.

The bee crisis has been treated as a niche concern until now, but as the UN's index of food prices hits an all time-high in real terms (not just nominal) and grain shortages trigger revolutions in the Middle East, it is becoming urgent to know whether the plight of the honey bee risks further exhausting our already thin margin of food global security.

The agri-business lender Rabobank said the numbers of US bee colonies failing to survive each winter has risen to 30pc to 35pc from an historical norm of 10pc. The rate is 20pc or higher in much of Europe, and the same pattern is emerging in Latin America and Asia.

Albert Einstein, who liked to make bold claims (often wrong), famously said that "if the bee disappeared off the surface of the globe, man would have only four years to live".

Such "apocalyptic scenarios" are overblown, said Rabobank. The staples of corn, wheat, and rice are all pollinated by wind.

However, animal pollination is essential for nuts, melons and berries, and plays varying roles in citrus fruits, apples, onions, broccoli, cabbage, sprouts, courgettes, peppers, aubergines, avocados, cucumbers, coconuts, tomatoes and broad beans, as well as coffee and cocoa.

This is the fastest growing and most valuable part of the global farm economy. Between 80pc and 90pc of pollination comes from domesticated honey bees. Moths and butterflies lack the range to penetrate large fields.

The reservoir of bees is dwindling to the point where ratios are dangerously out of kilter, with the US reaching the "most extreme" imbalance. Pollinated crop output has quadrupled since 1961, yet bee colonies have halved. The bee-per-hectare count has fallen nearly 90pc.

"Farmers have managed to produce with relatively fewer bee colonies up to this point, and there is no evidence of agricultural yields being affected. The question is how much further this situation can be stretched," said the report. 

In other words, the loss of America's bee colonies may not have caused the global food problems we're experiencing in 2011, but it's sure not helping the world recover.  More than ever, US farmers need healthy bees to pollinate crops.  If bees continue to vanish at their current rate, things could get very bad for the country and the world in only a few years.

It seems very few people are concerned about it, and I agree with Pritchard that it needs to change.
