    Every continent has reports of pollinator declines in at least one region/ country. The losses of pollination services have been well documented in many specifi c instances; what remains lacking are global assessments of changes in the distribution and levels of pollination services. As the recognized drivers of pollinator losses (changing land-use patterns, pesticide use, diseases, invasive species and climate change) are themselves changing in intensity, the global community is jus tifi ed in taking note and determining the actions that will conserve pollinators. The insidious nature of the loss of ecosystem services- by slow erosion rather than cataclysmic events- demands careful monitoring. Pollinators provide essential services to humans. In several instances, impressive documentation of the market and non-market values derived from pollination services has been made. Despite this, the economic valuation of pollination services has a number of challenges to overcome, many stemming from the gaps in understanding of the actual contribution of pollination to crop production. Developing sound management plans for pollinators will hinge on good taxonomic support. Linked to the taxonomic information about species is other information on biological characteristics (including fl oral relationships and ecological linkages) that are important for adaptive management. New approaches to managing pollinator information should help to overcome the taxonomic impediment, although the focus at present has been on bees, and not on other key pollinator groups.

    Pollinators 2019
    Disappearing pollinators can mean losing some of the nutritious food we need for a healthy diet. The decline of pollinators could have disastrous effects for our future of food. Their absence would jeopardize the three-quarters of the world’s crops that depend at least in part on pollination, including apples, avocadoes, pears and pumpkins. And enhancing pollination isn’t just about mitigating disaster – with improved management, pollination has the potential to increase agricultural yields and quality. Pollinators also play a crucial role in maintaining and enhancing biodiversity thus improving the resilience of plants to climate change and other environmental threats.

    Protection of honeybees and other pollinators: one global study 2021

    Insect populations are declining globally. Most crops rely on insect pollination, putting 23 food security at risk. Honeybees are important pollinators and have been used widely in 24 public awareness campaigns. This study surveyed countries about the status of their 25 pollinators and programmes for monitoring and management. Responses were received 26 from 273 persons from 108 countries. Apis mellifera was reported by nearly all 27 countries. Many countries (72%) routinely collect honeybee data and populations are 28 stable or increasing (77% of countries). Other pollinators receive less attention, 29 although their populations are dwindling in most (70%) countries. Conservation and 30 protection are more commonly practiced for honeybees. Most threats, such as habitat 31 loss and pesticides, are shared by all pollinators. Therefore, conservation measures to 32 decrease these threats would be efficient, provided that competition among species is 33 avoided. Monitoring of pollinator populations should be increased.
