New Report Issues Dire Warning About Global Decline in Pollinators
'Their health is directly linked to our own well-being.'
Feb 26, 2016
Pollinators worldwide, from bees and butterflies to beetles and bats, face a grim state of affairs.
Climate change and land use changes drive many pollinator species toward extinction, including 16 percent of vertebrate pollinators. A new report shows that over 40 percent of invertebrate pollinators, like bees and butterflies, may be threatened locally.
This all adds up to very bad news for humans, the report details, as it poses risks to the global food supply.
The assessment released Friday is from the four-year-old Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), a UN-formed body similar to the Intergovernmental Panel on Climate Change (IPCC). IPBES came to its first-ever analysis based on existing scientific studies.
"Pollinators are important contributors to world food production and nutritional security," said Vera Lucia Imperatriz-Fonseca, co-chair of the assessment and senior professor at the University of Sao Paulo. "Their health is directly linked to our well-being."
IPBES describes their critical role as three-quarters of the "leading types of global food crops" rely at least in part on pollination by some of the 20,000 species of wild bees or other pollinators. In terms of monetary impact, that translates to as much as $577 billion worth of annual global food production.
"Without pollinators, many of us would no longer be able to enjoy coffee, chocolate, and apples, among many other foods that are part of our daily lives," said Simon Potts, Ph.D., the other co-chair and professor of biodiversity and Ecosystem Services at the University of Reading in the UK.
In addition to climate change and changes in land use, the report cites the decline of practices based on indigenous and local knowledge and insecticides like neonicotinoids as contributing to the decline of pollinators.
Some strategies for protecting pollinators include promoting sustainable agriculture, reducing pesticide exposure, and increasing diversity in pollinator habitats.
As far as a real impact from the group's report, Dave Goulson, author, bumblebee expert, and professor of biology at the University of Sussex, is skeptical.
"I would question whether any practical on-the-ground action to help pollinators will happen due to this document. We are in the midst of the sixth global mass extinction event, and we sit around spending thousands of hours writing documents about biodiversity. Still, we do not take action to address the fundamental issues causing this ecological catastrophe," Nature reports him as saying.
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, The U.S. is on a fast track to authoritarianism like nothing I've ever seen. Meanwhile, corporate news outlets are utterly capitulating to Trump, twisting their coverage to avoid drawing his ire while lining up to stuff cash in his pockets. That's why I believe that Common Dreams is doing the best and most consequential reporting that we've ever done. Our small but mighty team is a progressive reporting powerhouse, covering the news every day that the corporate media never will. Our mission has always been simple: To inform. To inspire. And to ignite change for the common good. Now here's the key piece that I want all our readers to understand: None of this would be possible without your financial support. That's not just some fundraising cliche. It's the absolute and literal truth. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. Will you donate now to help power the nonprofit, independent reporting of Common Dreams? Thank you for being a vital member of our community. Together, we can keep independent journalism alive when it’s needed most. - Craig Brown, Co-founder |
