14 Pages, iZindaba Zokudla (IZ) is a multistakeholder engagement project that aims to create opportunities for urban agriculture in a sustainable food system in Johannesburg. IZ implements the Farmers’ Lab, a social lab used as a transitional mechanism in a larger transition to sustainability. To move the South African urban food system to an ecologically sound, economically productive, and socially equitable system, significant stakeholder integration is needed, and the iZindaba Zokudla Farmers’ Lab provides that. This reflective essay presents a history of the project (2013 until now) detailing the project’s creation of an ecosystem based on social labs that facilitate innovation in the food system. Emergent entrepreneurs and others use the social labs and their activities, as well as stakeholder engagement in their enterprise development, and these Labs have created opportunities for applied and other research in the university. This has brought innovation and change to agroecological practice in Johannesburg. This reflective essay article situates IZ within the broader evolutionary change in South Africa and considers how conversations about food lead to the creation of sustainable food systems.

14pgs, Urban agriculture (UA) can be used as an action to promote sustainability in cities and inform public health policies for urban populations. Despite this growing recognition, its implementation still presents challenges in countries in the Global North and Global South. Background: In this context, this systematic review aims to identify the development of frameworks for the implementation of UA as a sustainable action and its main opportunities and shortcomings in meeting urban socio-environmental demands. Methods: In this review, using the PRISMA protocol, we evaluated 26 studies on the interplay between UA and sustainability surveyed on the Web of Science to provide an overview of the state of the art. Conclusions: In summary, it was possible to identify many key challenges in UA adoption, which regard air and soil contamination, availability of green areas, layout of urban infrastructure, food distribution, among others. Due to numerous socio-economic and environmental contextual factors in cities, especially when comparing realities of the Global North and Global South, there is a need to develop a model that can be adaptable to these different contexts. Thus, it is recognized that the concept of sustainability does not present a universal understanding and that in its search it could be argued that one of the most important gaps is still to address social issues in relation to environmental ones.
8pgs, The global trend of urbanization coupled with an increasing awareness of the importance of food systems resilience, has led to an increasing interest in urban agriculture to sustainably feed the rapidly growing urban population and mitigate against food supply chain disruptions. While home and community gardens have been long studied, there has been relatively little empirical research focused specifically on commercial urban agriculture (CUA) operations. The purpose of this study was to characterize commercial urban farms, and to identify their primary barriers to business development and expansion, their perceptions of future opportunities, and their specific informational needs. Because CUA has received relatively less attention in previous empirical research, a qualitative approach was used for this needs assessment to collect rich, contextualized information to help differentiate the specific barriers, opportunities and needs of CUA operations as opposed to their rural counterparts. We conducted semi-structured interviews (n = 29) of CUA producers in Florida. These interviews revealed that CUA operations face many of the same barriers that are common to establishing and growing small farms, with additional barriers due to local government regulations and tensions associated with farming on land that is not traditionally used for agriculture. Despite these difficulties, CUA operators believe their urban location is a key benefit to their operation and they see a variety of opportunities for future business and market expansion.
17pgs, There is a lack of data on resources used and food produced at urban farms. This hampers attempts to quantify the environmental impacts of urban agriculture or craft policies for sustainable food production in cities. To address this gap, we used a citizen science approach to collect data from 72 urban agriculture sites, representing three types of spaces (urban farms, collective gardens, individual gardens), in five countries (France, Germany, Poland, United Kingdom, and United States). We answered three key questions about urban agriculture with this unprecedented dataset: (1) What are its land, water, nutrient, and energy demands? (2) How productive is it relative to conventional agriculture and across types of farms? and (3) What are its contributions to local biodiversity? We found that participant farms used dozens of inputs, most of which were organic (e.g., manure for fertilizers). Farms required on average 71.6 L of irrigation water, 5.5 L of compost, and 0.53 m2 of land per kilogram of harvested food. Irrigation was lower in individual gardens and higher in sites using drip irrigation. While extremely variable, yields at well-managed urban farms can exceed those of conventional counterparts. Although farm type did not predict yield, our cluster analysis demonstrated that individually managed leisure gardens had lower yields than other farms and gardens. Farms in our sample contributed significantly to local biodiversity, with an average of 20 different crops per farm not including ornamental plants. Aside from clarifying important trends in resource use at urban farms using a robust and open dataset, this study also raises numerous questions about how crop selection and growing practices influence the environmental impacts of growing food in cities. We conclude with a research agenda to tackle these and other pressing questions on resource use at urban farms.
21pgs, The concept of a regenerative city goes far beyond a sustainable one. The regenerative approach is to think of urban green space as a productive landscape, a source of food, and a support for biodiversity. In this approach, the so-called urban wastelands have a positive significance. Urban agriculture (UA) has become a commonly discussed topic in recent years with respect to sustainable development. Therefore, the combination of urban fabric and local food production is crucial for ecological reasons. The key issues are the reduction of food miles and the demand for processed food, the production of which strains the natural environment. At the same time, UA enables regeneration and restoration. An original methodological approach was used in the study following the mixed-method research concept: literature survey, case studies, and comparative analysis of objects. A review of UA architecture (UAA) projects was carried out to supplement the knowledge acquired during the bibliometric analysis. In sum, 25 existing projects, including allotment gardens, community gardens, and urban farms in the global north, were compared in this study. As a result of the analyses carried out, the breakdown of urban agriculture was developed into the following categories: (i) architectural–urban, (ii) ecological, (iii) social, and (iv) economic, including the impact of UA on physical activity and social interaction. UA is also a factor shaping the urban landscape. In conclusion, agrarian practice in urban environments has led to the creation of a new type of space, known as UAA. Production in the context of UA exceeds private goods, such as food produced for sale or for individual use. Additional goods include public goods. The review shows that UA fulfills economic, social, and environmental functions, thus falling under the concept of sustainable development.
