A spatial framework for targeting urban planning for pollinators and people with local stakeholders: A route to healthy, blossoming communities?

Abstract Pollinators such as bees and hoverflies are essential components of an urban ecosystem, supporting and contributing to the biodiversity, functioning, resilience and visual amenity of green infrastructure. Their urban habitats also deliver health and well‐being benefits to society, by providing important opportunities for accessing nature nearby to the homes of a growing majority of people living in towns and cities. However, many pollinator species are in decline, and the loss, degradation and fragmentation of natural habitats are some of the key drivers of this change. Urban planners and other practitioners need evidence to carefully prioritise where they focus their resources to provide and maintain a high quality, multifunctional green infrastructure network that supports pollinators and people. We provide a modelling framework to inform green infrastructure planning as a nature based solution with social and ecological benefits. We show how habitat suitability models (HSM) incorporating remote sensed vegetation data can provide important information on the influence of urban landcover composition and spatial configuration on species distributions across cities. Using Edinburgh, Scotland, as a case study city, we demonstrate this approach for bumble bees and hoverflies, providing high resolution predictive maps that identify pollinator habitat hotspots and pinch points across the city. By combining this spatial HSM output with health deprivation data, we highlight ‘win‐win’ opportunity areas in most need of improved green infrastructure to support pollinator habitat quality and connectivity, as well as societal health and well‐being. In addition, in collaboration with municipal planners, local stakeholders, and partners from a local greenspace learning alliance, we identified opportunities for citizen engagement activities to encourage interest in wildlife gardening as part of a ‘pollinator pledge’. We conclude that this quantitative, spatially explicit and transferable approach provides a useful decision‐making tool for targeting nature‐based solutions to improve biodiversity and increase environmental stewardship, with the aim of providing a more attractive city to live, work and invest in.

Cultivating nature-based solutions: The governance of communal urban gardens in the European Union

ABSTRACT In many countries in the European Union (EU), the popularity of communal urban gardening (CUG) on allotments and community gardens is on the rise. Given the role of this practice in increasing urban resilience, most notably social resilience, municipalities in the Global North are promoting CUG as a nature‐based solution (NbS). However, the mechanisms by which institutional actors can best support and facilitate CUG are understudied, which could create a gap between aspiration and reality. The aim of this study is therefore to identify what governance arrangements contribute to CUG delivering social resilience. Through the EU GREEN SURGE project, we studied six CUG initiatives from five EU‐countries, representing different planning regimes and traditions. We selected cases taking a locally unique or innovative approach to dealing with urban challenges. A variety of actors associated with each of the cases were interviewed to achieve as complete a picture as possible regarding important governance arrangements. A cross‐case comparison revealed a range of success factors, varying from clearly formulated objectives and regulations, municipal support, financial resources and social capital through to the availability of local food champions and facilitators engaging in community building. Municipalities can support CUG initiatives by moving beyond a rigid focus on top‐down control, while involved citizens can increase the impact of CUG by pursuing political, in addition to hands‐on, activities. We conclude that CUG has clear potential to act as a nature‐based solution if managed with sensitivity to local dynamics and context. HighlightsCommunal urban gardens benefit from combining hands‐on with political activity.The municipality plays a key role in facilitating communal urban gardens.Independent experimentation is key to innovation for communal urban gardens.Success is predicted by a fluent grassroots‐municipality power relationship.

Local government and urban forest governance: insights from Scotland

ABSTRACT While the benefits of urban forests (UFs) are well-researched, less is known about how to steer collective action for conserving and strengthening this resource, and particularly the role of local government. We address this knowledge gap through a study of urban forest governance in Scotland, United Kingdom. Applying a mixed-methods approach including semi-structured interviews, document analysis and surveys, covering 26 out of the total of 32 Scottish local authorities (LAs), we show that UF management by Scottish LAs is largely reactive. This can be explained by limited funding and knowledge of the resource, poor knowledge of the scale and state of the UF, fragmented management structures, and the tendency to perceive trees as a liability as opposed to an asset. However, some LAs successfully resist this trend through city officials acting as frontrunners within their organisations. They do so by championing activities such as investing in tools for socioeconomic valuation of the UF, pursuing grant funding, breaking down silos through organisational reorganisation, preparing city-level trees and woodland strategies, cross-sectoral partnership working and community engagement. Fundamental change, however, relies on the combination of these activities and therefore requires a whole-organisation commitment to UF sustainability across different domains relevant to predicting UF outcomes.

Co-creating urban green infrastructure connecting people and nature: A guiding framework and approach

Urban green infrastructure (UGI) and nature-based solutions are increasingly recognized as instruments to address urban sustainability challenges, yet rely on a good understanding of complex social-ecological system (SES) to function adequately. Adaptive co-management (ACM), engaging a broad variety of stakeholders in collaborative learning, is an effective strategy to improve the resilience of a SES. However, ACM studies have been criticized for neglecting the urban context, while also offering little clarity on process objectives and outcomes. To address these knowledge gaps, while also drawing attention to the important issue of socially inclusive UGI development, we present a guiding framework and approach to encourage the ACM of UGI featuring two main components. Firstly, a Learning Alliance (LA) serves as an instrument for collaborative learning and experimentation across different scales. To facilitate upscaling, we propose to establish a complementary Urban Learning Lab (ULL) to facilitate a regular exchange between the LA and legitimate peripheral networks and stakeholders in the city region. Secondly, a stepwise approach to SES analysis serves to engage a representative group of stakeholders in the LAs and ULLs, and support the processes of setting LA objectives and monitoring of adaptive capacity. We illustrate our approach to the ACM of UGI with a case study of LivadaLAB in Ljubljana, Slovenia. Applying the framework and approach, we demonstrate increased adaptive capacity of the SES around UGI as indicated by: 1) improved overall stakeholder salience, in particular for previously disempowered actor groups, 2) increased number and strength of connections between stakeholders, and 3) the consideration of a broader range of sustainable development objectives by stakeholders in their daily practice.
