Why don’t we go outside? – Perceived constraints for users of urban greenspace in Sweden

Urban greenspace (UGS) is important for human wellbeing, particularly physical and mental health, and is claimed to support social cohesion. However, the expansion and densification of urban centres in recent decades has occurred largely at the expense of UGS. This risks its attractiveness for users. Although recent research has identified various factors that influence the use of UGS in different contexts, few studies have taken an explicit, bottom-up approach to understand which factors constrain willingness to use it. This study analyses responses from an online survey in Sweden (N = 2806) to identify the main constraints to UGS usage, and for whom these are constraints. Respondents could select from 22 different types of constraints – relating to incivilities, management, accessibility and availability, safety, and personal issues. Respondents could also provide comments to identify additional constraints. Incivilities were the most perceived problem. For example, litter was selected by 53% of respondents, while vandalism was selected by 24%. At the same time, many respondents perceived few or no constraints – 59% stated that nothing prevented them from using UGS, while 35% stated that they saw no problems. Safety-related and accessibility/availability constraints were not strongly identified although many respondents commented that UGS in Sweden is inadequate given the large number of users, and that the UGS that people want to use the most is often inaccessible without a car. Multiple binary logistic regression was used to investigate relationships between perceptions of constraints and fourteen predictor variables. Odds ratios were used to determine whether significant (p < 0.05) relationships were meaningful. Our findings show that different groups have starkly divergent perceptions of constraints relating to UGS. Several key factors – including age, self-reported nature-connectedness, distance to UGS, and frequency of use – were associated with a heightened likelihood of perceiving different groups of constraints. However, relationships between constraints and factors relating to environmental justice were not straightforward. These findings indicate the complexity of UGS planning challenges relating to densification, the New Urban Agenda and promotion of societal benefits, and a need to further integrate multiple user perspectives, especially of younger adults and infrequent users.     

What motivations drive foreign gardeners to cultivate? Findings from urban gardening initiatives in Lombard municipalities

This paper examines the motivations that drive foreign gardeners to cultivate a garden in Lombard municipalities.Motivations underlying urban gardening are inspired by social, health, environmental and food-related benefits. Several studies document these benefits with reference to the entire population of gardeners, while ignoring the specific perspective of each social subgroup, mainly because of a lack of data. This scarce knowledge is particularly evident for the subset of foreign gardeners, i.e., migrants moving to Italy for work and/or family reasons who decide to cultivate an urban garden in the municipality of their residence. In turn, this prevents municipalities from adopting urban gardening projects that are consistent with the specific requirements of this group.As the regional government has legally recognized the importance of urban gardens and financed their realization, the Lombard municipalities have promoted many of these practices in their territories over recent years. However, neither the region nor the municipalities have created a database of these practices or collected information on the motivations that lead people in general – and foreign citizens in particular – to cultivate locally.This paper aims to fill that gap by presenting some results gained from the elaboration of two questionnaires sent to both the municipalities and the gardeners themselves.Findings indicate that about 21 % of the responding municipalities promote urban gardening initiatives. Of these municipalities, less than one in five have at least one foreign gardener. Foreign gardeners come mainly from North Africa and Eastern Europe, most of them are over 40 years old, and have usually lived with their families in Lombard municipalities for more than five years. Their motivations consist of a growing interest in participation in local communities, breaching multiple relationships and enforcing participation. Conversely, they attribute little importance to sharing values and strengthening personal and social identities, or to preserving the social ecological memory of ancient practices. Finally, they frequently highlight the contribution of garden cultivation in reducing pollution and in reconnection with food practices, making access to good food a priority.     

Modeling of urban trees’ effects on reducing human exposure to UV radiation in Seoul,Korea

A mathematical model is constructed for quantifying urban trees’ effects on mitigating the intensity of ultraviolet (UV) radiation on the ground within different land use types across a city. The model is based upon local field data, meteorological data and equations designed to predict the reduced UV fraction due to trees at the ground level. Trees in Seoul, Korea (2010), produced average UV protection factors (UPF) for pedestrians in tree shade at solar noon (May to August) of 8.3 for park and cemetery land uses and 3.0 for commercial and transportation land uses. The highest daily UPF was 11.8 in the park and cemetery land uses, which has the highest percent canopy cover. This UV model is being implemented within the i-Tree modeling system to allow cities across the world to estimate tree effects on UV exposure. Understanding the impacts of urban trees on UV exposure can be used in developing landscape design strategies to help protect urban populations from UV exposure and consequent health impacts.     

Critical upscaling. How citizens’ initiatives can contribute to a transition in governance and quality of urban greenspace

Studies show that municipalities often develop a type of urban greenspace that is rather uniform in its shape and use. Citizens’ initiatives develop different types of greenspace. This article uses concepts from transition studies and identifies what happens during a citizens’ initiative in urban greenspace in the Netherlands in terms of transition of municipal management and development and how these initiatives can lead to a change of practices of the municipality. A single, qualitative study of Diepenheim Inside-Out-Forest in the Netherlands as a critical case is presented, based on 8 semi-open interviews. The study gives insight in how the municipality has changed in relation to this one case, and how such transition of ‘regime’ takes place. The study explains how the different benefits that arise in a greenspace development and management initiative relate to the ‘critical knowledge’ and ‘situated knowledge’ of the actors involved and that the quality of urban greenspace is very much the result of that knowledge. ‘Fit and conform’ and ‘stretch and transform’ are usable strategies for the empowerment of such initiatives through sharing of resources, and policy advocacy by ‘critical niche’ innovators.‘Regime’ is not uniquely a feature of the local state but also of market parties and citizens themselves with their own values and routines. A change among all parties seems needed if greenspace is to be developed, managed and used differently.
