The waterfront community of Sydhavn in Copenhagen, Denmark is architecturally praised, but also criticized for its lack of public green space. Residents in the area have self-organized a community gardening initiative to combat this lack of greenery. The thesis aims to explore this occurrence by providing an analysis of the attitudes and behaviors towards social and environmental aspects of sustainability and individual residents’ resistance or support towards community gardening initiatives. The research design is based on quantitative methods with an exploratory purpose, using an online survey methodology. The main findings show that there is an association among knowledge of sustainability concepts, sustainable attitudes and behaviors, and interest in community gardening participation in the study population. Moreover, individuals who indicate no interest in community gardening lack a desire to join in the future, although they may be encouraged to do so with more education and advertisement. Generally, the study population feels positively towards community gardening and feels there is a need for it in the area. Further research may investigate aspects such as politics and policies related to community gardening and replicate a similar study in a different sociodemographic context to see how the results differ. The results of this study have practical implications for academics, built environment practitioners, and community gardening organizers.
