The study presented here investigates the involvement of adults with intellectual disability in community gardens on the basis of four case studies in Vienna. The issue is, that the potential of and for this group in community gardens is not recognized and realized jet. The following research questions were therefore pursued: How is this group of persons involved in community gardens; what strengths/opportunities and what weaknesses/threats are connected with their involvement; what are the motivations for the participants; and to what extent are the respective goals achieved? The results of the case studies were accomplished through participant observations and qualitative interviews. The data were evaluated through summarizing content analysis according to Mayring (2010). The focus in the literature review is set on the inclusion approach. To identify the contributions by adults with intellectual disability to community gardens, as well as vice versa, collation with theoretical approaches to types of capital (Bourdieu, 2005; Putnam, 2000), community capital (Smit & Bailkey, 2006) and resources (Schubert & Knecht, 2012) proved useful. The results presented contribute to the understanding of the ways in which the process of inclusion of adults with intellectual disability in community gardens, and ultimately in the wider community, is promoted and inhibited. On one hand, this group of persons contributes to the construction of community capital in community garden initiatives through its personal resources. On the other hand, the community capital gained by community garden initiatives also flows back to these people. Other involved persons, participating organizations and the environment contribute also to the generation of environmental resources for adults with intellectual disability and community capital in community gardens.
