Despite extensive literature on the socio-cultural services of urban open spaces, the role of food-producing spaces has not received sufficient attention. This hampers advocacy for preserving and growing urban agricultural activities, often dismissed on justifications that their contributions to overall food supply are negligible. To understand how the social benefits of urban agriculture have been measured, we conducted a systematic review of 272 peer-reviewed publications, which drew on insights from urban agriculture sites in 57 different countries. Through content analysis, we investigated socio-cultural benefits in four spheres: engaged and cohesive communities, health and well-being, economic opportunities, and education. The analysis revealed growth in research on the social impacts of gardens and farms, with most studies measuring the effects on community cohesion and engagement, followed by increased availability and consumption of fruits and vegetables associated with reduced food insecurity and better health. Fewer studies assessed the impact of urban farming on educational and economic outcomes. Quantifying the multiple ways in which urban agriculture provides benefits to people will empower planners and the private sector to justify future investments. These findings are also informative for research theorizing cities as socio-ecological systems and broader efforts to measure the benefits of urban agriculture, in its many forms.

Urban allotment gardens (AGs) provide a unique combination of productive and recreational spaces for the inhabitants of European cities. Although the reasons behind the decision to have a plot, as well as the mode of use and gardening practices, are well recognised in the literature, these issues are mainly considered in relation to particular case studies within a single country. The regional diversity of European allotment gardens is still poorly understood, however. This knowledge gap became an incentive for us to carry out the present study. The research was conducted in seven countries: Austria, Estonia, Germany, France, Portugal, Poland and the UK. Surveys were used to assess the motivations of users regarding plot uses and gardening practices. Information was also collected during desk research and study visits, making use of available statistical data. Allotment gardens in Europe are currently very diverse, and vary depending on the historical, legal, economic and social conditions of a given country, and also as determined by geographical location. Three main types of plots were distinguished, for: cultivation, recreation–cultivation, and cultivation–recreation. The recreational use of AGs has replaced their use for food production in countries with a long history of urban gardening. The only exception is the UK. In some countries, the production of food on an AG plot is still its main function; however, the motivations for this are related to better quality and taste (the UK), as well as the economic benefits of self-grown fruits and vegetables (Portugal, Estonia). Among the wide range of motivations for urban gardening in Europe, there is increasing emphasis on active recreation, contact with nature and quality food supply.

The quality of life of big city dwellers depends on the use of green infrastructure. The idea of a compact city, opposed to urban sprawl, can lead to reduced access to green areas and increased demand for cultural services provided through urban green infrastructure. Considering the above, the aim of the paper was to identify the supply of and demand for cultural ecosystem services related to the urban green spaces in densely built-up urban areas. To find out how important the ability to use green areas for dwellers of the densely built-up areas is, the questionnaire interviews with the residents of the area of the Old Town of Poznan were conducted. Questions in the survey concerned the amount of green spaces and their availability, the way of use, types of activity, factors limiting the use and factors encouraging to visit green spaces and the motives for using green areas away from inhabitants' place of residence. Respondents claim that there is not enough greenery, especially associated with housing and street side greenery; the amount of parks (which they use most) is slightly higher, in their opinion. Limitations that influence utilising green spaces concern both greenery itself (e.g. insufficient recreational infrastructure, neglected green areas) as well as respondent's issues (e.g. lack of free time). Improvements to recreational infrastructure and more well-kept green spaces would encourage respondents to utilise it more often. Active participation of inhabitants in developing and maintaining their closest neighbourhood would allow to enlarge green spaces in housing areas and make them more customized to the residents' needs and requirements in terms of functionality and aesthetic.

The aim of the study was to analyse the quality of soil in urban allotment gardens in the context of the production of home-grown vegetables. The study was conducted on six allotment gardens (31 individual plots) in Gorzów Wielkopolski, a medium-sized Polish city with an average level of industrialisation. The following soil characteristics were analysed: pH, electric conductivity, organic matter, organic carbon, humus, total nitrogen, C:N ratio, NH₄⁺-N, NO₃-N⁻, P, K, Ca, Mg, SO₄⁻-S, Cl, Na, Fe, Cu, Zn, Mn, Ni, Cr, Cd, Pb. The analyses showed that the soils were abundant in necessary nutrients for vegetable growing. They had high content of calcium, magnesium, and phosphorus. However, the soil pH in areas of vegetable cropping was too high. The content of toxic heavy metals—cadmium (0.22–0.59 mg∙kg⁻¹ d.m.) and lead (3.46–16.89 mg∙kg⁻¹ d.m.)—was within the acceptable limits. Nevertheless, the chemical analysis of carrots used as test vegetables showed that the permissible limits of cadmium and lead content in their roots were exceeded. The excessive uptake of these toxic metals can be reduced by lowering the soil pH and applying organic carbon to the soil.

Multifunctional allotment gardens are an important part of the green infrastructure of cities. In spite of this, they are given little attention in the plans and policies of cities. One of the major threats to the existence of allotment gardens within the spatial structure of cities is the pressure of investment, which results from an underestimation of the role of gardens. The task of preserving allotment gardens in the ecosystems of cities rests with the local spatial planning. Urban spatial policy towards allotment gardening is exemplified by the case study of Poznan. The bases for the analysis include the study of the conditions and directions of spatial planning, as the spatial policy document that sets forth the city and local spatial development plans, which are Acts of local laws.

Living close to green infrastructure (GI) components might be the dream of many people who are often exposed to cities’ pollution, congestion, or lack of green amenities. Due to its multiple benefits, green infrastructure plays a significant role in driving people’s decisions to leave inner-city areas and move to suburban locations. However, how GI components are used once people move into the suburbs must be better understood. Thus, this study explores residents’ rationales for leaving the inner city and moving to the suburbs and how they use suburban GI components. A survey was undertaken in six suburbs from three European cities: Poznań (Poland), Salzburg (Austria), and Bucharest (Romania). We found that people self-reported that green amenities were the main reason for choosing a suburban residence. Furthermore, those residents who moved to the suburbs were more interested in using their private gardens than larger parks and prefer natural green areas with high potential for recreation to agricultural landscapes for leisure. This study advocates for investment in private green spaces in suburban developments due to their deep interweaving with residents’ leisure preferences.
