Alternative = transformative? Investigating drivers of transformation in alternative food networks in Germany

In the hope for more sustainable agriculture and a stronger connection to their food, an increasing number of consumers participate in alternative food networks (AFNs) characterised by short food supply chains. However, it cannot be assumed that AFNs inherently transform the prevailing system and its respective practices around food. Thus, we apply a social innovation perspective to enable a comprehensive analysis of changed values, social practices and relations in AFNs. This article presents whether drivers of transformation occur in three different AFN models (Community Supported Agriculture (CSA), food co‐operatives (food co‐ops) and self‐harvest gardens) and how participants describe and perceive them in each model. Therefore, we conducted interviews with AFN producers and consumers, before applying qualitative content analysis. Interviewees describe a broad variety of transformed values, practices and relations: Especially CSA and food co‐ops bear transformative potential as their members report a strong reconnection of producers and consumers expressed through social interaction and community‐building. Self‐harvest gardeners predominantly seek individual capacity building and to have access to their own garden. We conclude that AFN participation fosters incremental transformation towards more sustainable practices around food and a respective value system, which can be a part of a bigger movement aimed at food system transformation.Federal Ministry of Education and Research http://dx.doi.org/10.13039/501100002347Peer Reviewe

Consumers’ and Stakeholders’ Acceptance of Indoor Agritecture in Shanghai (China)

During recent decades, there has been increasing awareness of the development of “agritecture” (“agri”culture + archi“tecture”) as a means to transform and revolutionize the food supply of future cities. The different forms of agritecture include building-integrated agricultural concepts such as vertical farms or indoor farms. In this way, urban food production could take place in proximity to consumers while employing so-called “urban waste” products (such as wastewater, waste heat, and organic waste) as valuable production inputs. Although scholars frequently highlight the potential of vertical farming and other agritecture approaches for Asian megacities, there is still a lack of academic research and completed projects related to this field in China. This study uses a mixed-methods approach, combining quantitative and qualitative research in the study location of Shanghai, to reveal the social acceptance of indoor agritecture among consumers and experts. First, to explore the perceptions of consumers, a survey of 713 potential consumers was conducted in Shanghai. Second, these surveys were complemented by 20 expert interviews with academics and practitioners from Shanghai to frame the quantitative research results. Our results revealed that the surveyed consumers’ social acceptance of indoor agritecture and the expectations of the experts are high. Additionally, there is already a high level of demand and a potential market for indoor agritecture in Shanghai. This has been confirmed by the ongoing construction of the first moderate-scale vertical farm and several indoor farms, in combination with the increasing existence of edible landscape approaches and rooftop farms. This development can be viewed as the rise of urban agritecture in Shanghai. The interviews revealed that experts raise more doubts about the economic dimension, whereas its social and ecological dimensions and the contextual framework of indoor agritecture are considered to be positive.Peer Reviewe

Assessing motivations and perceptions of stakeholders in urban agriculture: a review and analytical framework

Interest in the adoption of urban agriculture (UA) has grown in recent years. The compatibility of UA with the urban social context, in particular with urban stake- holders' attitudes, is crucial for its successful implementation and represents one of the key factors influencing its development. To this end, a literature review on different approaches to analysing stakeholders' and farmers' perceptions of UA is performed. The paper identifies the main approaches to assessing these aspects and designs an integrated framework to support the development of context-tailored analytical approaches for UA drivers' and stakeholder perceptions. The study aims to address and solve potential conflicts between UA practitioners and urban stake- holders and adapt the implementation of UA to contextual factors. This increases the possibility of developing successful UA strategies that meet the challenges currently facing urban food systems

How Can Innovation in Urban Agriculture Contribute to Sustainability? A Characterization and Evaluation Study from Five Western European Cities

Compared to rural agriculture, urban agriculture (UA) has some distinct features (e.g., the limited land access, alternative growing media, unique legal environments or the non-production-related missions) that encourage the development of new practices, i.e., \u201cnovelties\u201d or \u201cinnovations\u201d. This paper aims to (1) identify the \u201ctriggers\u201d for novelty production in UA; (2) characterize the different kinds of novelties applied in UA; (3) evaluate the \u201cinnovativeness\u201d of those social, environmental and economic novelties; and, (4) estimate the links between novelties and sustainability. The study was based on the evaluation of 11 case studies in four Western European countries (Italy, Germany, France and Spain). The results show that the trigger and origin of new activities can often be traced back to specific problems that initiators were intended to address or solve. In total, we found 147 novelties produced in the 11 case studies. More novelties are produced in the environmental and social dimensions of sustainability than in the economic. In most cases, external stakeholders played an important role in supporting the projects. The analysis further suggests that innovativeness enhances the overall sustainability in urban agriculture projects

Moreover, cities have to become or remain livable for their inhabitants and offer social and economic opportunities. Thus, reconnecting food production and cities offers promising potential. The diffusion of urban farming reflects a rising awareness of how food and farming can shape our cities. A growing number of urban farming projects exist in and on urban buildings, including open rooftop farms, rooftop greenhouses and indoor farming. These projects are characterized by the non-use of land or acreage for farming activities. We use the term ‘Zero-Acreage Farming’ (ZFarming) to represent these farms. The objective of this paper is to: (1) illustrate and systemize present practices of ZFarming and (2) discuss specific novelties of ZFarming in the wider context of urban agriculture. We analyzed 73 ZFarms in cities of North America, Asia, Australia and Europe using a set of criteria, and developed a typology of ZFarming, complemented by in-depth interviews with pioneers in rooftop farming in New York. The results illustrate that ZFarming generates innovative practices that may contribute to a sustainable urban agriculture. Besides growing food, it produces a range of non-food and non-market goods. It involves new opportunities for resource efficiency, new farming technologies, specific implementation processes and networks, new patterns of food supply and new urban spaces

An Aggregated Stakeholder Perspective on Potential Benefits and Challenges

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). They 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

"We have been part of the response": The Effects of COVID-19 on Community and Allotment Gardens in the Global North

This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). https://creativecommons.org/licenses/by/4.0/Throughout history, urban agriculture practitioners have adapted to various challenges by continuing to provide food and social benefits. Urban gardens and farms have also responded to sudden political, economic, ecological, and social crises: wartime food shortages; urban disinvestment and property abandonment; earthquakes and floods; climate-change induced weather events; and global economic disruptions. This paper examines the effects on, and responses by, urban farms and gardens to the COVID-19 pandemic. The paper is based on data collected in the summer of 2020 at the onset of the pandemic when cities were struggling with appropriate responses to curb its spread. It builds on an international research project (FEW-meter) that developed a methodology to measure material and social benefits of urban agriculture (UA) in five countries (France, Germany, Poland, UK and USA) over two growing seasons, from a Food-Energy-Water nexus perspective. We surveyed project partners to ascertain the effects of COVID-19 on those gardens and farms and we interviewed policy stakeholders in each country to investigate the wider impacts of the pandemic on UA. We report the results with respect to five key areas: (1) garden accessibility and service provision during the pandemic; (2) adjustments to operational arrangements; (3) effects on production; (4) support for urban farms and gardens through the pandemic; and (5) thoughts about the future of urban agriculture in the recovery period and beyond. The paper shows that the pandemic resulted in multiple challenges to gardens and farms including the loss of ability to provide support services, lost income, and reductions in output because of reduced labor supply. But COVID-19 also created several opportunities: new markets to sell food locally; more time available to gardeners to work in their allotments; and increased community cohesion as neighboring gardeners looked out for one another. By illustrating the range of challenges faced by the pandemic, and strategies to address challenges used by different farms and gardens, the paper illustrates how gardens in this pandemic have adapted to become more resilient and suggests lessons for pandemic recovery and longer-term planning to enable UA to respond to future public health and other crises.Peer reviewe
