ABSTRACT
It is estimated that 15% of the world’s food is produced within a variety of landscapes generally classified as ‘urban’ (Armar-Klemesu 2000). Urban agriculture is especially common in developing countries (van Veenhuizen 2000). However, crops are increasingly grown in industrialized nations as well, predominantly in community, residential and rooftop gardens (Lawson 2005). Vegetables and fruits grown in gardens and other urban green spaces provide food security for those living in poverty (Brown and Jameton 2000) and nutrition for many who live in neighborhoods that lack affordable sources of fresh produce (Horowitz et al. 2004).
