The Global Pollination Crisis

The Global Pollination Crisis

(p.620) Chapter 29 The Global Pollination Crisis
Pollination and Floral Ecology

Pat Willmer

Princeton University Press

This chapter focuses on the global pollination crisis. For nearly three decades now there has been evidence of declines in pollinators worldwide, and the problems were explicitly recognized in the United Nations Sao Paulo declaration (1998–1999). However, the ecosystem-level effects of this pollinator decline remain unclear. Therefore long-term data collections are needed to track the changes and to understand their underlying causes with a view to finding sustainable solutions. This chapter examines the needs for assessment of pollinator declines, along with some of the key threats to pollinators and to pollination services including: habitat degradation and destruction; habitat fragmentation; intensive agriculture; increasing prevalence of fires in areas where human impacts are substantial; introduced animal species and pollinators; invasive plant species and changing floras; diseases and other natural threats to key pollinators; and climate change.

Keywords:   pollinator, pollinator declines, pollination crisis, habitat degradation, habitat fragmentation, intensive agriculture, invasive plant species, disease, climate change, fire
