Abstract:

The world’s growing population and growing need for food have increased attention to urban agriculture around the world. Most crops grown in urban environments need bees for pollination. However, little is known about bee populations in urban areas and little attention has been paid to the function of these pollinators in cities. Therefore, studying the ecology of pollinating bees in urban gardens and green roofs contributes greatly to urban agriculture. In the present study, the results of 106 articles related to the presence of bees in gardens and urban farms were summarized in three general sections. The first part deals with issues such as the diversity of bees in urban gardens, the predominant species in these areas, their body size, nesting type, and origin, being specialist or general, social or solitary. The second part examines the diversity of host plants in urban gardens and farms, their origin, and attractiveness for bees. The third section examines the effects of landscape and local variables effects on the presence of bees in urban farms and gardens. Our data showed that the relationships between bees and urban gardens are complex and in most cases, the results of these studies are contradictory. In the first part of the results, our data showed that urban environments, especially urban gardens, contain a high diversity of bees, which provides a good opportunity for urban agriculture. The results of the second part showed that no general conclusion could be considered about the effects of host plant origin on pollinator augment. In the third section, most studies emphasized the negative role of urbanization on the presence of bees. On the other hand, many studies have shown that the presence of green spaces or other farms and gardens around the studied gardens had a positive effect on the presence of pollinators
