Loss of wild pollinators could threaten food security

The loss of wild pollinators from agricultural landscapes could threaten global crop yields, a study has found.

Led by Lucas Garibaldi, an assistant professor at the National University of Río Negro in Argentina, a team of researchers compared fields containing many wild pollinators — mostly insects — with those containing few. They studied 41 crop systems across all continents except Antarctica to understand how the loss of wild pollinators impacts crop production.
