Chennai, March 11, 2011: Honey bees and other pollinators are under threat with serious implications for biodiversity and food security, according to the report1 published on March 10, 2011 by the United Nations Environment Programme (UNEP) containing the findings and recommendations by a team of researchers including Dr. Neumann, Swiss Bee Research Centre, Dr. Chauzat, French Agency for Environmental and Occupational Health Safety, and Dr. Pettis of the United States Department of Agriculture's Agricultural Research Service.
The Report finds that several factors are responsible for declines in bee populations. These include habitat deterioration, air pollution, crop spraying and the widespread use of insecticides in plant cultivation. Decline in populations of bees would mean that tens of thousands of plant species could be lost in coming years unless conservation efforts are stepped up.
Following is the Press Release dated March 10, 2011 by the UNEP on the occasion of the 'Launch' of the Report.

From Chemicals to Air Pollution, New UNEP Report Points to Multiple Factors Behind Pollinator Losses
Geneva/Nairobi, March 10, 2011: More than a dozen factors, ranging from declines in flowering plants and the use of memory-damaging insecticides to the world-wide spread of pests and air pollution, may be behind the emerging decline of bee colonies across many parts of the globe.
Scientists are warning that without profound changes to the way human beings manage the planet, declines in pollinators needed to feed a growing global population are likely to continue.
- New kinds of virulent fungal pathogens - which can be deadly to bees and other key pollinating insects - are now being detected world-wide, migrating from one region to another as a result of shipments linked to globalization and rapidly growing international trade.
- Meanwhile an estimated 20,000 flowering plant species, upon which many bee species depend for food could be lost over the coming decades unless conservation efforts are stepped up.
- Increasing use of chemicals in agriculture, including systemic insecticides and those used to coat seeds, is being found to be damaging or toxic to bees. Some can, in combination, be even more potent to pollinators, a phenomenon known as the 'cocktail effect'.
- Climate change, left unaddressed, may aggravate the situation, in various ways including by changing the flowering times of plants and shifting rainfall patterns. This may in turn affect the quality and quantity of nectar supplies.
These are among the findings of a new report published today by the UN Environment Programme (UNEP), which has brought together and analyzed the latest science on collapsing bee colonies.
The study, entitled Global Bee Colony Disorders and other Threats to Insect Pollinators, underlines that multiple factors are at work linked with the way humans are rapidly changing the conditions and the ground rules that support life on Earth. It shows humans' large dependency on ecosystem services even for such vital sectors as food production.
It indicates that bees are early warning indicators of wider impacts on animal and plant life and that measures to boost pollinators could not only improve food security but also the fate of many other economically and environmentally important plants and animals.
The authors of the report call for farmers and landowners to be offered incentives to restore pollinator-friendly habitats, including key flowering plants next to crop-producing fields.
More care needs to be taken in he choice, timing and application of insecticides and other chemicals. While managed hives can be moved out of harms way. "Wild populations (of pollinators) are completely vulnerable", says the report.
Achim Steiner, UN Under-Secretary-General and UNEP Executive Director, said: "The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century. 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."
Bees and the Green Economy
Next year nations gather again in Rio de Janeiro, 20 years after the Rio Earth Summit, to evolve international efforts to achieve sustainable development including through accelerating and scaling-up a transition to a low carbon, resource-efficient Green Economy.
Part of that transition should include investing and re-investing in the world's nature-based services generated by forests and fresh waters to flower meadows and coral reefs.
"Rio+20 is an opportunity to move beyond narrow definitions of wealth and to bring the often invisible, multi-trillion dollar services of nature - including pollination from insects such as bees - into national and global accounts," said Mr. Steiner.
"Some countries, such as Brazil and India, have already embarked on that transformation as part of a partnership between UNEP and the World Bank. It is time to widen and embed this work across the global economy in order to tip the scales in favour of management rather than mining of the natural world and that includes the services of pollinators," he added.
The new report on bee colony disorders has been led by researchers Dr. Peter Neumann of the Swiss Bee Research Centre and Dr. Marie-Pierre Chauzat of the French Agency for Environmental and Occupational Health Safety. The team also included Dr. Jeffrey Pettis of the United States Department of Agriculture's Agricultural Research Service.
Dr. Neumann said: "The transformation of the countryside and rural areas in the past half century or so has triggered a decline in wild-living bees and other pollinators. Society is increasingly investing in 'industrial-scale' hives and managed colonies to make up the shortfall and going so far as to truck bees around to farms and fields in order to maintain our food supplies."
"This report underlines that a variety of factors are making these man-made colonies increasingly vulnerable to decline and collapse. We need to better manage the landscape beyond, in order to cost-effectively recover wild bee populations to far healthier and more sustainable levels," he added.
