The Age of Diversity as Vertovec referred to has been marked not only by the growth of population in the cities but also by the increment of a diverse and ethnically heterogeneous demographic. As urban areas continue to grow rapidly in all regions, this diverse context reconfigures human relations between and within urban societies. Thus, diversity can be seen from two dimensions, one in which a diverse population brings a positive force for an urban economic development or, one dimension in which diversity can be seen as the source of community tensions and challenges for urban development.By bringing urban and migration studies into dialogue, the study through two distinctive methodologies (semi-structured interviews and participant observation), explores Community Gardens as urban spaces in Oslo city and tries to find out if these urban spaces are creating social cohesion in a diverse city.The theoretical framework of this thesis is presented as follows: firstly, the diversity concept which is the lens through which this research is carried out will be discussed. Secondly the concept of social cohesion will be presented followed by the social capital concept. This latter will be used as an analytical tool that helps us to understand the empirical material.Results from this comparative case-study work shows how urban community gardens in Oslo contribute to generate bonding, bridging and linking social capital, thus, helping to build social cohesion. The location, the CG spatial characteristics, and the management of the community gardens seem to be distinctive variables that might contribute to the variation in the composition of these capitals among the case-study gardens.This thesis also suggests directions for future research and inform urban policy about the importance of the inclusive potential of the UCG for the development of a city with a diverse population.
