About 35 percent of global food production depends on the services of pollinating insects. Tropical fruits such as mango, spice plants and medicinal plant species, numerous crops such as cotton and some 80 percent of wild plants all require pollination.

A workshop on pollinators was held at COP 9 in Bonn. The outcomes of the workshop have now been published as part of the BfN-Skripten publication series: Caring for Pollinators – Safeguarding Agro-Biodiversity and Wild Plant Diversity. The book brings together the presentations and posters from the workshop in revised and extended form and provides information about the main producing countries and groups of pollinator species. Profiles of the main pollinator groups summarise the available knowledge on the biology of pollinators and the ecological services they provide. This is the only generally available, up-to-date publication on the subject.
