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.

Since the 1950s, intensification and scale enlargement of agriculture have changed agricultural landscapes across Europe. The intensification and scale enlargement of farming was initially driven by the large-scale application of synthetic fertilizers, mechanization and subsidies of the European Common Agricultural Policy (CAP). Then, after the 1990s, a further intensification and scale enlargement, and land abandonment in less favored areas was caused by globalization of commodity markets and CAP reforms. The landscape changes during the past six decades have changed the flows and values of ecosystem services. Here, we have reviewed the literature on agricultural policies and management, landscape structure and composition, and the contribution of ecosystem services to regional competitiveness. The objective was to define an analytical framework to determine and assess ecosystem services at the landscape scale. In contrast to natural ecosystems, ecosystem service flows and values in agricultural landscapes are often a result of interactions between agricultural management and ecological structures. We describe how land management by farmers and other land managers relates to landscape structure and composition. We also examine the influence of commodity markets and policies on the behavior of land managers. Additionally, we studied the influence of consumer demand on flows and values of the ecosystem services that originate from the agricultural landscape.

Peri-urbanisation, as a process of the physical expansion of settlement areas but also socioeconomic transformation, has been recognised as a major spatial development beyond the urban fringes. Agriculture, the main land use actor in the hinterlands of many urban areas is increasingly affected by urban encroachment, responds with adaptation strategies and farming activities to cope with the peri-urban framework conditions. Adaptation pathways encompass specialisation into horticulture as well as enhanced environmental and lifestyle orientation of farming-typical elements of multifunctional agriculture. However, due to the heterogeneity of the periurbanisation processes also differences in farming transition are expected. Based on a differentiation into displaced-urbanisation, ex-urbanisation, anti-urbanisation and hidden-urbanisation as main types of peri-urbanisation, variances of farming responses are elaborated for municipal entities in the Copenhagen region in Denmark using statistical census data. Under consideration of location determinants, regression models have been applied to analyse the interrelationship between different peri-urbanisation processes and multifunctional farming activities. Findings confirm that the differentiation of peri-urban processes is meaningful for the explanation of spatial distribution of farm adaptation strategies, particularly in the case of leisure and environmental oriented farm practices.

Alternative food networks (AFNs) are growing in number and relevance in Germany. Those networks include new models of production and distribution, such as food cooperatives (FoodCoops), self-harvest gardens or community-supported agriculture (CSA) schemes. AFNs, as an alternative to conventional food supply systems, are characterized by a close producer-consumer interaction.They are typically located within urban or peri-urban areas. The study aims to identify the rationale and motivation of urban residents in participating in AFNs and developing a consumer typology.We also assess whether AFNs potentially lead to collective action with societal impact. Therefore, we conducted a qualitative content analysis based on 18 interviews with members of existing AFN projects in three German metropolitan regions. Our results revealed that the willingness of urban consumers to participate in AFNs is driven by a broad range of motives. They include personal desire for high-quality food (in terms of taste or freshness) and health reasons, but also political or environmental motives (opposition to conventional agriculture or short transport distances).Furthermore, consumers often want to support a certain farmer and his/her philosophy or they appreciate the community-building aspect. Three different consumer types were derived from the motive combinations. Many consumers communicated a sense of belonging to a societal movement, however, our study revealed a lack of organization and collective action. Although AFNs can influence the consumption patterns of individuals, their potential to induce social change and to challenge traditional models of consumption in the near future does not appear to be high.
