Summary

This global modelling study quantifies the human health burden of pollinator decline by estimating yield losses in fruits, vegetables, nuts and legumes due to inadequate pollination, and translating these losses into dietary risk and mortality outcomes across countries. The authors employed climate-zonation approaches and comparative risk assessment to show that insufficient pollination contributes to substantial preventable mortality, with impacts distributed unequally between lower-income (production) and higher-income (consumption/mortality) countries. The work integrates agricultural, economic, and epidemiological models to demonstrate that pollinator conservation has direct and measurable consequences for human nutrition and disease burden.

UK applicability

The United Kingdom produces and imports pollinator-dependent fruits, vegetables and nuts; whilst the study's production impacts may be concentrated in lower-income regions, UK consumers and food security would benefit from improved global pollinator health. The findings support UK policy arguments for domestic and international pollinator protection through agricultural reform and land management.

Key measures

Yield gaps for animal-pollinated foods; proportion of gap attributable to insufficient pollinators; changes in food production, trade, and consumption; excess deaths by country; economic value of lost crop production

Outcomes reported

The study modelled the global health burden attributable to insufficient pollination of crops. It estimated excess annual mortality from reduced consumption of pollinator-dependent foods and quantified economic losses in case-study countries.
