This review evaluates the importance of animal pollination for global crop production, using primary data from 200 countries. It finds that 87 out of 137 leading global food crops depend on animal pollination, while 28 do not. However, globally, 60% of production comes from crops that do not rely on animal pollination, 35% from those that do, and 5% are unevaluated. The study also assesses the level of dependence on animal-mediated pollination for crops directly consumed by humans, finding that 13 crops are essential, 30 highly dependent, 27 moderately dependent, 21 slightly dependent, 7 unimportant, and 9 of unknown significance. The review highlights the negative impacts of agricultural intensification on wild bee communities and their role in maintaining pollination services at the landscape scale. It recommends landscape management practices to enhance wild pollinator densities, such as increasing nesting opportunities, providing floral resources, enhancing habitat connectivity, and reducing pesticide use. The review underscores the need for more research on crop pollination and better coordination of efforts to sustain crop production and biodiversity.This review evaluates the importance of animal pollination for global crop production, using primary data from 200 countries.
