Decreasing pollination services are not compensated by intense agriculture
Intensification of agriculture is justified with the growth of human population and food security. On the other hand, a decrease of pollinator diversity and pollination services is observed on local scales. To examine whether these findings scale up on larger scales was examined by a french team (doi:10.1890/130054). They studied data of 54 major crops in France over the past 20 years. They found that the benefits of agricultural intensification decreased with the pollinator dependence of the crop. Intensification failed to increase the yield in pollinator dependent crops and decreased the yield stability over time. The authors conclude that intensification of agriculture must be performed in a sustainable way to maintain ecological services as pollination.
