Hamburg's agriculture is an example of local sustainability challenges in the food system: Despite urban utopias, technological visions, civil society initiatives and demands for regional, environmentally friendly, sustainable production and marketing in the agricultural sector, the potential of urban agriculture has not yet been used as a momentum for innovative business concepts, sustainable lifestyles, contributions to climate and environmental goals and regional economic dynamics of a sustainable agriculture and food industry in the city-regional area (Feldmann et. al. 2023). The surrounding farms have been supplying the growing metropolis with agricultural products for centuries, in particular vegetables, ornamental plants and cut flowers from the Vier- und Marschlanden and fruit from the Altes Land. Despite this tradition on the one hand and many visions and experiments in the field of urban gardening on the other, local agriculture in Hamburg is coming under increasing pressure: population growth requires more housing to be built, sometimes on land previously used for agriculture, such as in Oberbillwerder or the new garden city of Öjendorf. Experts agree that the connections between city dwellers interested in gardening and commercial horticulture must be established and strengthened in order to shape the field of tension between urbanization, regionality and relocalization, health awareness, urban gardening and digitalization with innovative, integrative and sustainable concepts of urban agriculture.
The project aims to establish an innovation area for urban agriculture as part of the urban development of the Neue Gartenstadt Öjendorf on land previously used for agriculture in Hamburg. Together with our cooperation partners HafenCity University Hamburg and the Julius Kühn Institute, our department is developing a conceptual framework for the participatory development and testing of plausible business scenarios for various innovation models for horticultural production, value creation and marketing. The aim is to help integrate the wide variety of forms of urban agriculture in a context-specific manner into a viable, transferable demonstration model and development process for urban agriculture.
