This paper introduces the notion of community gardens as multipurpose, technological systems with dynamic boundaries. It also strives to revise the notion of food security and health in regards to such systems. This is a cross-cultural project where twelve community gardens located in urban regions within three different countries were examined. This paper explores common tendencies rather than diversities or differences. The paper describes a behavioural chain that depends on various factors and affects various types of health. It is suggested that a community garden has the potential to serve as a link between the past and the present. While a community garden may provide food, it is suggested that it may also encourage social interactions, knowledge sharing, and relaxation. The cultivation of food occurs, but it may not always be the sole purpose.
