“…Growing interest of consumers, inhabitants, and local stakeholders provide urban market opportunities [20,52]. Direct sale is a common strategy to create added value within densely populated areas [20,55]. Consumers are willing to pay higher prices for locally and transparently grown food [12,56].…”

“…Consumers are willing to pay higher prices for locally and transparently grown food [12,56]. Thus, urban farmers progressively apply direct sale due to nearby urban consumer potentials, newly emerging and intensifying urban demands for regional food of high quality, higher turnovers, and reduced vulnerability to macroeconomic fluctuations [3,[8][9][10]52,55,57]. Direct sale arrangements enable higher margins due to better control over prices, but demand also financial resources, knowledge, and additional labor force.…”

Consumer-oriented diversification activities, such as direct sale ("deepening") as well as tourism services and care farming ("broadening"), are common business strategies of farms within urban areas. This empirical study investigates determinants of urban farming's diversification decisions by analyzing a dataset of 123 farmers in German Ruhr Metropolis. Binary logit models are used here as econometric method to determine characteristics influencing the decision to diversify. Farm characteristics, which encourage the implementation of "deepening" strategies, are: larger farm sizes, high-value production, organic farming, and livestock production. By contrast, the consumer-oriented "broadening" strategies tourism services and care farming prevail on smaller farms and on farms with horses and higher grassland shares. Agricultural extension services increase the odds to diversify. The results of the conducted binary logistic regressions show increasing odds and predicted probabilities for "deepening" and "broadening" activities when approaching the city. Farms' location advantages close to cities can be used best when applying consumer-oriented "deepening" or "broadening" strategies; namely, direct sale or other short supply chains, tourism services, and care farming. Viable business strategies of urban farming support a forward-looking integration into urban economy, society, and decision-making.

“…Scholars from various disciplines and throughout the world have addressed how urban production can serve as a new framework to change the common practice of food production, food processing, food transport and consumption [3,[7][8][9][10][11][12][13]. The underlying principle of the productive urban city can even contain a shift of common conceptions when it reaches a point where "rural" and "urban" categories themselves no longer clearly denote legible spatial units any longer [14] and cities are being defined as "Continuous Productive Urban Landscapes" [7].…”

Zero-Acreage Farming in the City of Berlin: An Aggregated Stakeholder Perspective on Potential Benefits and Challenges

et al. 2015

How can buildings be combined with agricultural production and what are the major potential benefits and challenges for the introduction of zero-acreage farming (ZFarming) in Berlin from the relevant stakeholders' perspectives? These questions were explored through a series of interviews and stakeholder workshops held between 2011 and 2013. The aim was to identify the most suitable building-integrated farming model for the Berlin metropolitan area and to develop guidelines for the model's successful and sustainable implementation through a stakeholder-driven approach. This paper provides an aggregated synthesis of the outcomes derived from the qualitative interviews and stakeholder workshops. As the results reveal, the stakeholders perceive potential benefits and challenges related to the issue of ZFarming in all dimensions (economic, social, environmental and political). OPEN ACCESSSustainability 2015, 7 4512They largely agreed on the importance of focusing on local resources, using energy-efficient production-including social and educational aspects-and developing new market structures when introducing ZFarming to the city of Berlin. The stakeholders identified urban rooftop greenhouses (RTG) as the most promising farming model for Berlin. In a joint collaboration of all stakeholders, a manual for RTG was developed within the participatory innovation process that addresses the identified problems and challenges associated with future implementation and governance of RTG in Berlin and beyond.

“…Worldwide urbanization is increasing rapidly, especially in developing countries representing a rate of 3.6 % per year from 1950 until 2005 compared with industrialized countries which only had a growth rate of 1.4 % (Aubry et al 2012). In 2008, the global urban population overtook the rural population for the first time in history.…”

Global food production faces great challenges in the future. With a future world population of 9.6 billion by 2050, rising urbanization, decreasing arable land, and weather extremes due to climate change, global agriculture is under pressure. While today over 50 % of the world population live in cities, by 2030, the number will rise to 70 %. In addition, global emissions have to be kept in mind. Currently, agriculture accounts for around 20-30 % of global greenhouse gas emissions. Shifting food production to locations with high demands reduces emissions and mitigates climate change. Urban horticulture increases global food production by exploiting new locations for cultivation. However, higher land prices and urban pollution constrain urban horticulture. In this paper, we review different urban cultivation systems throughout the world. Our main findings from ecological, economical, and social aspects are: (1) Urban horticulture activities are increasing globally with at least 100 million people involved worldwide. With potential yields of up to 50 kg per m 2 per year and more, vegetable production is the most significant component of urban food production which contributes to global food security. (2) Organoponic and other low-input systems will continue to play an important role for a sustainable and secure food production in the future. (3) Despite the resource efficiency of indoor farming systems, they are still very expensive. (4) Integrating urban horticulture into educational and social programs improves nutrition and food security. Overlaying these, new technologies in horticultural research need to be adopted for urban horticulture to increase future efficiency and productivity. To enhance sustainability, urban horticulture has to be integrated into the urban planning process and supported through policies. However, future food production should not be "local at any price," but rather committed to increase sustainability.
