With the prevalence of smartphones, new ways of engaging citizens and stakeholders in urban planning and governance are emerging. The technologies in smartphones allow citizens to act as sensors of their environment, producing and sharing rich spatial data useful for new types of collaborative governance set-ups. Data derived from Volunteered Geographic Information (VGI) can support accessible, transparent, democratic, inclusive, and locally-based governance situations of interest to planners, citizens, politicians, and scientists. However, there are still uncertainties about how to actually conduct this in practice. This study explores how social media VGI can be used to document spatial tendencies regarding citizens’ uses and perceptions of urban nature with relevance for urban green space governance. Via the hashtag #sharingcph, created by the City of Copenhagen in 2014, VGI data consisting of geo-referenced images were collected from Instagram, categorised according to their content and analysed according to their spatial distribution patterns. The results show specific spatial distributions of the images and main hotspots. Many possibilities and much potential of using VGI for generating, sharing, visualising and communicating knowledge about citizens’ spatial uses and preferences exist, but as a tool to support scientific and democratic interaction, VGI data is challenged by practical, technical and ethical concerns. More research is needed in order to better understand the usefulness and application of this rich data source to governance.

Green (and blue) spaces receive attention as important components of cities that can help to mitigate the effects of climate change, support biodiversity and improve public health. Green space planning aims to transform cities towards urban sustainability and resilience. In a longitudinal study, representatives from eleven European municipalities that had previously been interviewed in 2014 were re-interviewed in 2020–2021 on changes in urban greening and related practices. The interviewees reported mainly advancements in dealing with ecological issues, such as new plans, strategies, regulations or funding programmes for climate adaptation or biodiversity support, as well as some progress in co-governance with non-governmental stakeholders. Promising developments include breaking professional silos by creating new units that can better deal with complex urban issues. In a few cases, high-level local politicians induced profound changes. These changes stimulated the development of new planning and governance cultures, resulting in more co-creation of urban green spaces. However, from a transformation studies perspective, incremental strategies dominate, and even when municipal representatives are aware that substantive changes are needed, they often lack the means to act. For more radical system change, significant extra efforts are needed.

Nature-based therapy can be considered an umbrella term for a diverse range of psychotherapeutic and allied practices which integrate experiences and activities in nature as therapeutic means. The objective of this article is to describe the theoretical framework for nature-based therapy in a university-founded healing forest garden near Copenhagen, Denmark. The garden will offer a 10-week treatment for people who are on sick leave with stress-related illness. This article focuses on clarifying the integration between the psychotherapeutic and gardening aspects of the nature-based therapy. The psychotherapeutic aspects are based on mindfulness and an acceptance therapy, while the gardening aspects are highly inspired by permacultural principles and methods.

In the unfolding reality of advanced internet-based communication tools, the possibilities and implications for citizens’ e-engagement is revealing. The paper introduces different examples of e-tools used in participatory urban green infrastructure governance. E-tools here includes various location-based service apps, and volunteered geographic information stemming from social media activities, as well as public participation geographic information system approaches. Through an analytical framework describing five categories, we discuss the different scopes and possibilities, as well as general barriers and problems to participatory e-tools. We suggest some basic premises for the application of e-tools in urban green infrastructure governance and discussed future development of this field. E-tools can allow interaction between citizens, public authorities, and other stakeholders; however, research on the implications of such location-based governance is needed to make full use of the rapid on-going development of such information and communication technologies, and to avoid possible pitfalls. We suggest that future research into this area of environmental–social–technical solutions should test, discuss, and develop frameworks and standards, for the use of different e-tools in combination with offline approaches.
