As the urban population grows worldwide and cities are becoming increasingly unequal and segregated, Urban Commons emerge as a potential driver of inclusion and resilience for city dwellers. According to Feinberg et al. (2021), Urban Commons can promote social, environmental, and economic resilience, and Park et al. (2020) suggest they can act as a haven for the excluded. Commons could, therefore, become a policy alternative to address the grand urban challenges of the 21st Century. However, it is still unclear whether the benefits of Urban Commons are ultimately accessible to the culturally and socioeconomically vulnerable. For instance, in a literature review study, Huron (2017) found significant uncertainties in how Urban Commons relate to feminism, race, gender, and ethnicity – factors that could constitute immaterial barriers of access, following Vrasti & Dayal’s (2017) terminology. In fact, while several studies have investigated the commons’ role in promoting urban justice, explorations of whether access to the commons itself is just have been neglected. This master’s thesis explores what constitutes material and immaterial barriers to accessing Urban Commons to understand whether these initiatives can work, policy-wise, as a driver of social inclusion. 29 Urban Commons in Amsterdam were selected as a case study. A quantitative geo-spatial analysis was conducted to evaluate the material accessibility to each initiative. In parallel, commoners were surveyed about their perception of immaterial barriers and benefits of commoning. Finally, a representative of the municipality of Amsterdam was interviewed to assess the potential challenges and benefits of policies involving Urban Commons. Concurring with Park et al. (2020), the case study findings suggest commons could indeed promote social inclusion. Moreover, it was also found that the excluded could face, in addition to the initially proposed material and immaterial walls, an ecosystem barrier to access commons. Yet this could be addressed from a policy standpoint with the development of a commons ecosystem that is capable of scaling the benefits of commoning across an entire city. The results have academic and societal relevance. This study provides a new theoretical framework to research the factors influencing access to commons and also contributes to literature with a unique city-wide case study. It can also function as a reference for policy-makers who wish to learn about the commons landscape in Amsterdam and who interested in understanding the factors that contribute to participation in a commons.
