An IBA [International Building Exhibition], Germany's most influential urban regeneration tool, is currently facilitating 'innovative, knowledge-based' urban development in the City of Heidelberg. One of its 'urban laboratories' is the Urban Agriculture Park which provides a prototype for planning and designing urbanisation in an agricultural setting.

Bohn&Viljoen acted as productive urban landscape and urban agricultural experts to the project and, for the IBA, led the participatory design process with local initiative Interessengruppe Heidelberg engaging local residents, farmers, council administrators and politicians, community gardeners and local institutions.
