Innovative forms of green urban architecture aim to combine food, production, and design to produce food on a larger scale in and on buildings in urban areas. It includes rooftop gardens, rooftop greenhouses, indoor farms, and other building-related forms. This study uses the framework of sustainability to understand the role of ZFarming in future urban food production and to review the major benefits and limitations. The results are based on an analysis of 96 documents published in accessible international resources. The (...) analysis shows that ZFarming has multiple functions and produces a range of non-food and non-market goods that may have positive impacts on the urban setting. It promises environmental benefits resulting from the saving and recycling of resources and reduced food miles. Social advantages include improving community food security, the provision of educational facilities, linking consumers to food production, and serving as a design inspiration. In economic terms it provides potential public benefits and commodity outputs. However, managing ZFarming faces several challenges. For some applications, the required technologies are known but have not been used or combined in that way before; others will need entirely new materials or cultivation techniques. Further critical aspects are the problem of high investment costs, exclusionary effects, and a lack of acceptance. In conclusion, ZFarming is seen as an outside-the-box solution which has some potential in generating win–win scenarios in cities. Nevertheless, ZFarming practices are not in and of themselves sustainable and need to be managed properly. (shrink)

Rooftop gardens, rooftop greenhouses and indoor farms have been established or planned by activists and private companies in Berlin. These projects promise to produce a range of goods that could have positive impacts on the urban setting but also carry a number of risks and uncertainties. In this early innovation phase, the relevant stakeholders’ perceptions and social acceptance of ZFarming represent important preconditions for success or failure of the further diffusion of this practice. We used the framework of acceptance to (...) investigate the stakeholders’ attitudes and to identify the key factors that might hinder or promote the introduction of ZFarming. The results are based on an analysis of 38 qualitative interviews conducted with key stakeholders in Berlin. As the results show, major perceived benefits of ZFarming include improved consumer awareness, education, and the creation of experimental spaces. Stakeholders further perceive opportunities for resource savings, new business models, repurposing of abandoned buildings and improved aesthetics. Major perceived risks are associated with growing techniques that are considered “unnatural”, health risks, conflicts with images of traditional agriculture, the rejection of animal production in urban areas, the risk of projects being too expensive and too complex or being implemented too early, i.e. before the mechanisms are fully understood. The analysis further reveals which contextual factors—political, legal, market-related, spatial or societal—might negatively or positively influence ZFarming acceptance. (shrink)

Plant-based milk alternatives–or mylks–have surged in popularity over the past ten years. We consider the politics and consumer subjectivities fostered by mylks as part of the broader trend towards ‘plant-based’ food. We demonstrate how mylk companies inherit and strategically deploy positive framings of milk as wholesome and convenient, as well as negative framings of dairy as environmentally damaging and cruel, to position plant-based as the ‘better’ alternative. By navigating this affective landscape, brands attempt to make mylk as simultaneously palatable and (...) disruptive to the status quo. We examine the politics of mylks through the concept of palatable disruption, where people are encouraged to care about the environment, health, and animal welfare enough to adopt mylks but to ultimately remain consumers of a commodity food. By encouraging consumers to reach for “plant-based” as a way to cope with environmental catastrophe and a life out of balance, mylks promote a neoliberal ethic: they individualize systemic problems and further entrench market mechanisms as solutions, thereby reinforcing the political economy of industrial agriculture. In conclusion, we reflect on the limits of the current plant-based trend for transitioning to more just and sustainable food production and consumption. (shrink)
