Friends of the Earth discuss bees here.

An extract from the link above: You can make a huge difference where you live by doing a few simple things.
Planting flowers rich in nectar will really help bees find the food they need. Choosing local, British honey will lend your support to our honey bees and their beekeepers. Encouraging your friends and neighbours to do the same will help create bee-friendly communities.
Bees are crucial in the countryside but they’re essential in the city too. A wild window box in the middle of the urban jungle has great value. A whole building covered in window boxes is even more useful and looks fantastic.
