The CPUL concept
A Continuous Productive Urban Landscape (CPUL) is an urban (green) infrastructure linking food-producing sites of varying scales and operating types with other (green) open spaces across towns or cities thereby connecting those parcels of land to the citizens, to other food system activities and ultimately to the rural landscape. Bohn & Viljoen (2005)
The CPUL City concept describes an urban future based on the planned and designed introduction of Continuous Productive Urban Landscapes – interconnected food-productive landscapes defined by urban agriculture – into existing and emerging cities. CPUL City is an environmental design strategy and has fundamental physical and social implications. It follows a systemic approach and proposes that urban agriculture can contribute to more sustainable and resilient food systems while also adding beneficially to the spatial and socioeconomical quality of the urban realm.
A CPUL facilitates activities across all parts of the urban food system. It will not meet all of a city’s food needs, but it could meet about a third in fruit and vegetable requirements. Viljoen & Bohn (2000)
