Summary
This modelling study quantifies the global health burden and economic costs of insufficient pollination in agriculture. The authors estimate that inadequate pollinator populations cause 3–5% annual losses in fruit, vegetable, and nut production globally, resulting in approximately 427,000 excess deaths annually from lost healthy food consumption and associated non-communicable diseases. The analysis reveals unequal impacts: low-income countries experience concentrated production losses whilst disease burden falls disproportionately on middle- and high-income countries with higher baseline rates of chronic disease.
UK applicability
The UK's horticultural sector, particularly soft fruit and vegetable production, depends substantially on animal pollination; findings highlight risks from pollinator decline in domestic and imported supply chains. UK policy frameworks addressing pesticide use and habitat management for pollinators may benefit from evidence on health returns from pollinator conservation.
Key measures
Pollinator-related crop yield gap; lost consumption of pollination-dependent foods by country and region; excess annual deaths; economic value of crop production losses
Outcomes reported
The study modelled global impacts of insufficient pollination on human health and economic crop value, quantifying crop yield losses and excess mortality attributable to reduced consumption of pollination-dependent foods. Country-level and regional analyses were conducted, with case studies from Honduras, Nepal, and Nigeria.
