Bees reared in cities are healthier and more productive than their country cousins, a study by French beekeepers' association Unaf has found.
Urban bees enjoy higher temperatures and a wider variety of plant life for pollination, while avoiding ill-effects of pesticides, the study said.
At the same time they can filter out city pollution such as exhaust fumes.
The study prompted Unaf to start a campaign promoting beekeeping in urban parks, on balconies and on roofs.
Beekeepers say urban bees' productivity can be up to four times that of their rural counterparts. . .
