Introduction:

Global honey bee colony disorder and other threats to insect pollinators

By UNEP Division of Early Warning Assessment, 2010.

This bulletin published by UNEP considers the latest scientific findings and analyses possible answers to the threats faced by insect pollinators. It asks the question: Has a ‘pollinator crisis’ really been occurring during recent decades, or are these concerns just another sign of global biodiversity decline? As the bee group is the most important pollinator worldwide, this bulletin focuses on the instability of wild and managed bee populations, the driving forces, potential mitigating measures and recommendations. Currently available global data and knowledge on the decline of pollinators are not sufficiently conclusive to demonstrate that there is a worldwide pollinator and related crop production crisis. Data indicate that global agriculture has become increasingly pollinator dependant over the last 50 years and pollination is not just a free service but one that requires investment and stewardship to protect and sustain it.
