Bee colony collapse, once limited to Europe and America, is now being seen in Asia and Africa. alamyBy Michael McCarthy, Environment Editor

The mysterious collapse of honey-bee colonies is becoming a global phenomenon, scientists working for the United Nations have revealed. Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are also now being observed in China and Japan and there are the first signs of African collapses from Egypt, according to the report from the United Nations Environment Programme (UNEP). The authors, who include some of the world’s leading honey-bee experts, issue a stark warning about the disappearance of bees, which are increasingly important as crop pollinators around the globe. Without profound changes to the way human beings manage the planet, they say, declines in pollinators needed to feed a growing global population are likely to continue. The scientists warn that a number of factors may now be coming together to hit bee colonies around the world, ranging from declines in flowering plants and the use of damaging insecticides, to the worldwide spread of pests and air pollution. They call for farmers and landowners to be offered incentives to restore pollinator-friendly habitats, including key flowering plants near crop-producing fields and stress that more care needs to be taken in the choice, timing and application of insecticides and other chemicals. While managed hives can be moved out of harm’s way, “wild populations (of pollinators) are completely vulnerable”, says the report. “The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century,” said Achim Steiner, UN Under-Secretary-General and UNEP Executive Director. “The fact is that of the 100 crop species that provide 90 per cent of the world’s food, over 70 are pollinated by bees. “Human beings have fabricated the illusion that in the 21st century they have the technological prowess to be independent of nature. “Bees underline the reality that we are more, not less, dependent on nature’s services in a world of close to seven billion people.” …
