Pollinators are crucial for the production of many global food crops, with 87 of the leading crops depending on animal pollination, while 28 do not. However, global production data show that 60% of food comes from crops not relying on pollinators, 35% from pollinator-dependent crops, and 5% are unassessed. The study found that 13 crops are essential for pollinators, 30 are highly dependent, 27 moderately, 21 slightly, 7 unimportant, and 9 unknown. Agricultural intensification threatens wild bee communities and their pollination services. Case studies across four continents show that wild bees are vital for pollination, and their decline could jeopardize crop diversity and production. The review emphasizes the need for landscape management to support wild pollinators, including habitat conservation, floral resources, and reduced pesticide use. Research is needed to better understand pollinator requirements and the impact of pollinator loss on crop production. The study highlights the importance of pollinators in global food systems and the risks of relying solely on managed honeybees. Effective management practices are essential to ensure pollination services for future crop production.Pollinators are crucial for the production of many global food crops, with 87 of the leading crops depending on animal pollination, while 28 do not.
