Urbanization was once associated with the threat of population decline in bees, but now many cities are using their limited space to boost local agriculture and business. Furthermore, bees travel within a 2-3 kilometer radius to collect nectar from plants and trees. For this reason, only backyard space is required for bee colonies to nest.
In addition to urban hobbyists wanting to develop self-sufficient lifestyles, some businesses, such as restaurants and department stores, have started keeping beehives on their rooftops. This contributes to a sustainable urban economy. Self-harvested honey and other honey-based products can be an appealing attraction to customers. It also promotes the consumption of local produce while reducing the time and cost of food transportation.
