A broad understanding of food systems includes a complex web of activities, outcomes and drivers, encompassing not only the food and agriculture sectors, but also the social norms and cultures in which those activities are embedded. The organic food and farming movement has lately been portrayed as a food system of its own right, since it contains all necessary sub-systems, consisting of food environments, distribution networks, processing, as well as production and supply, all of which are bounded by an organic guarantee system. The underlying hypothesis of this investigation is that drivers in the organic food system operate on a paradigm level that is associated with the codified principles of ecology, health, fairness and care. Personality science suggests that the choice to act in pro-environmental ways is driven by an internalized sense of obligation or personal norms, which justifies our pursuit of seeking key drivers of food systems in the mindset of the actor. Through integrated findings from actor-centered mixed methods grounded theory research involving eleven case territories, this study identified a pattern of global mindset attributes that intuitively drive organic food system actors toward holistic human and sustainable development.

Recent discussion about future energy production promotes the recovery of industrial heat as a potential solution to reduce carbon emissions. Experts call for an expansion of central heating by renewable energy systems to ensure a decarbonization of energy systems. In this context, district heating could play a significant role in city and district planning. Nonetheless, for private households, environmental aspects are only one factor amongst others as, e.g., capital costs, comfort and security. In this study, we focus on private household preferences and willingness-to-pay for district heating and district heating from renewables compared to gas condensing boilers and heat pumps. For the study, we decided to apply a discrete-choice experiment and collected data on attitudes towards sustainability, economic aspects and demands for providers of heat supply as dimensions for a factor and cluster analysis in order to apply a market segmentation. The results show that district heating by renewables is the most preferred heating option for households followed by district heating from fossil fuels, heat pumps and gas boilers. Furthermore, the study offers more profound insight into the willingness-to-pay for each heating option and reports interaction effects for the different market segments that could be identified in the analysis.

Socio-economic viability of urban agriculture (UA) is, especially regarding non-commercially oriented initiatives, at most a generically treated issue in scientific literature. Given a lack of data on yields, labor input, or saved expenditures, only a few studies have described it either from a cost-avoidance or a specific benefit generation perspective. Our hypothesis is that hybrid roles of consumers and producers in urban agriculture challenge the appraisal of socio-economic viability. This paper presents an empirical study from three prevalent urban agriculture models: self-harvesting gardens, intercultural gardens, and community gardens, combining qualitative and quantitative survey data. A multi-value qualitative comparative analysis was applied to grasp the perception of socio-economic viability and its success factors. This allowed us to identify necessary and sufficient conditions for economic and social success. Results give an indication of the existence of different value systems and cost–benefit considerations in different urban agriculture models. A service-focused business relationship between farmers and consumers ensuring self-reliance is important for success for self-harvesting gardens, while self-reliance and sharing components are relevant for intercultural gardens. Community gardening builds upon self-governance ambitions and a rather individually determined success and failure factor pattern beyond explicit production output orientation. It is shown here for the first time with a quantitative approach that participants of urban agriculture models seem to go beyond traditional trade-off considerations and rather adopt a post-productive perception, focusing more on benefits than costs.

Urban agriculture, a dynamic multifunctional phenomenon, affects the spatial diversification of urban land use, its valorization and its governance. Literature acknowledges its contribution to the development of sustainable cities. The dimension and extent of this contribution depends significantly on the particular form and function of urban agriculture. However, the complexity of interests and dimensions is insufficiently covered by theory. This paper proposes a typology for urban agriculture, supporting both theory building and practical decision processes. We reviewed and mapped the diversity of the types of agriculture found along three beneficial dimensions (self-supply, socio-cultural, commercial) for product distribution scale and actors. We distinguish between ideal types, subtypes and mixed types. Our intention is to include a dynamic perspective in the typology of urban agricultural land use because transition processes between types are observable due to the existence of complex motivations and influences. In a pilot study of 52 urban agriculture initiatives in Germany, we tested the validity of the typology and discussed it with stakeholders, proving novelty and relevance for profiling discussions.

Food security is becoming an increasingly relevant topic in the Global North, especially in urban areas. Because such areas do not always have good access to nutritionally adequate food, the question of how to supply them is an urgent priority in order to maintain a healthy population. Urban and peri-urban agriculture, as sources of local fresh food, could play an important role. Whereas some scholars do not differentiate between peri-urban and urban agriculture, seeing them as a single entity, our hypothesis is that they are distinct, and that this has important consequences for food security and other issues. This has knock-on effects for food system planning and has not yet been appropriately analysed. The objectives of this study are to provide a systematic understanding of urban and peri-urban agriculture in the Global North, showing their similarities and differences, and to analyse their impact on urban food security. To this end, an extensive literature review was conducted, resulting in the identification and comparison of their spatial, ecological and socio-economic characteristics. The findings are discussed in terms of their impact on food security in relation to the four levels of the food system: food production, processing, distribution and consumption. The results show that urban and peri-urban agriculture in the Global North indeed differ in most of their characteristics and consequently also in their ability to meet the food needs of urban inhabitants. While urban agriculture still meets food needs mainly at the household level, peri-urban agriculture can provide larger quantities and has broader distribution pathways, giving it a separate status in terms of food security. Nevertheless, both possess (unused) potential, making them valuable for urban food planning, and both face similar threats regarding urbanisation pressures, necessitating adequate planning measures.

Foundations in Germany were examined in the context of environmental issues. Data from environmental foundations show that there is huge difference between private and public foundations concerning financial settings. Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.
