Bees boost crops and could steady food prices

Supporting and enhancing pollinators could help stabilize the production of important crops like oilseeds and fruit, reducing the sort of uncertainty that causes food price spikes, new research has shown.
Scientists at the University of Reading analyzed years of data on the poorly understood effect of pollinators on crop yield stability. They found there was 32% less variation in the yields of plants visited by bees and other pollinators than those grown in the absence of pollinators.
The study, published in the journal Ecology Letters, suggests that pollinators can help to mitigate supply issues and market shocks that cause global price spikes, like those being seen this year, by holding food supplies steady.
The publication marked the start of Bees’ Needs Week 2022 (18-24 July), a UK Government-led campaign championing pollinators and their benefits.
Dr. Jake Bishop, a crop science researcher at the University of Reading, who led the study, said: “Our findings suggest that preserving pollinators provides a double benefit, reducing fluctuations in food supplies as well as boosting supplies in the first place.
“Stable and predictable production of nutritious food is a necessity for farmers and for global food security. We are seeing right now that instability or shocks across the food system can lead to dramatic increases in food price.
“The research has revealed another reason why pollinators are so important to our planet, and to so many families who are struggling to feed themselves with sufficient, safe, and nutritious food.
“Pollinators are particularly important in the production of fruit and vegetable crops. Around half of the experiments we analyzed were testing the effect of real pollinator populations in real crop fields so our results illustrate the benefits that pollinators are currently providing.”
Raised and stable baseline
While the benefits of pollinators to crop yield are well known, their effect on crop stability was poorly understood until now.
The new research combined the results of more than 200 previous experiments which compared the yield of crop plants with and without insect pollination. The study focused on three globally important and representative crop species: faba bean, oilseed rape, and apples.
The study tested the effects of pollination on yield stability within individual plants and fields as well as across larger spaces. Insect pollination consistently made yields more similar between flowers on a plant, between individual plants, areas within fields, or between fields.
