Nature-based innovation systems

Transitions literature regards technologies as critical components in shifting systems towards sustainability, which has informed the development of the technology-oriented Technological Innovation System (TIS) framework. The emerging discourse on nature-based solutions (NBS) – multifunctional nature-integrated spatial planning and design innovations – raises the question to what extent TIS can account for the development and diffusion of NBS. Following a literature review, we present the Nature-Based Innovation System (NBIS) framework delineating critical factors for urban nature-based innovation. We find both commonalities and differences between TIS and NBIS, suggesting that the roles of place-based dynamics, agency and governance structure are more central to nature-based innovation, and market formation is more central to technological innovation. This has implications for the study of sustainability transitions, which has likely underplayed the potential of innovations at the nexus of socio-technical and socio-ecological systems. Future research is needed to refine the NBIS framework, for example by studying evolutionary developmental trajectories

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

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

Planning multifunctional green infrastructure for compact cities:What is the state of practice?

Urban green infrastructure planning aims to develop green space networks on limited space in compact cities. Multifunctionality is considered key to achieving this goal as it supports planning practice that considers the ability of green spaces to provide multiple benefits concurrently. However, multifunctionality is an elusive concept and little information is available on how it is perceived and actioned by planners. Therefore, this paper will examine the application of the multifunctionality concept in urban planning based on a semi-quantitative study, including interviews with chief planners and analyses of planning documents, in 20 European cities as well as three qualitative good practice case studies. The semi-quantitative study revealed a broad awareness of the variety of social and ecological functions provided by green spaces in planning. Yet, the analysed strategic plans contained little information on how to enhance multifunctionality. Regardless of the lack of details, cities facing growth were more likely to consider promoting multifunctionality as a planning aim. The qualitative case studies in Germany (Berlin), the United Kingdom (Edinburgh) and Denmark (Aarhus) provided a detailed insight into how multifunctionality is handled on different spatial scales and revealed great differences from academic multifunctionality approaches that were developed in the context of ecosystem service assessments. The approaches applied in practice include audits based on indicators for multiple green space functions or the purposive design and management of multifunctional parks. Based on the findings, we arrive at five recommendations for promoting multifunctional urban green infrastructure in densifying urban areas: 1) undertake systematic spatial assessments of all urban green (and blue) spaces and their social, ecological and economic functions; 2) include standards and guidelines for multifunctionality in city-wide strategic planning; 3) encourage design and management for multifunctionality at the site-level while considering that not all sites must deliver the same set of functions. Further, spatial assessment, strategic planning and site design need to 4) consider synergies, trade-offs and the capacity of urban green spaces to provide functions as part of the wider green infrastructure network; and 5) largely benefit from cooperation between different sectors and public departments. These recommendations can also be instructive for research on ecosystem service assessments in order to develop approaches that more strongly correspond to the demands of planning practice

The long-term prospects of citizens managing urban green space : From place making to place-keeping?

This paper discusses the long-term management or ‘place-keeping’ of urban green space by citizens and highlights enabling and constraining factors that play a crucial role in this continuity. While authorities have historically been in charge of managing public green spaces, there is an increased involvement of citizens in green space management. It is therefore relevant to study how citizens can contribute towards place-keeping and realize a continuity in managing and conserving the qualities of urban green spaces. We contribute to these debates by looking at three European cases characterized by long-term involvement of citizens in place-keeping. We conducted document analysis and interviewing of key informants to study green space management over time. Our analysis highlights what factors have contributed towards the continuity ofthis management, but also shows challenges and difficulties which citizens have experienced. Based on our fieldwork, we identify three factors of particular relevance for the continuity of place-keeping involving citizens. We found that long-term continuity is supported by a degree of formalization: established rules and procedures within groups provide stability to citizens. We also highlight the importance of adaptive capacity: citizens need to be able to adapt to contextual changes in order to cope with external political, socio-economic and cultural developments over time. The supporting role of authorities was also key in legitimizing and supporting placekeeping by citizens. Authorities can support place-keeping by citizens by providing security via stable policies,formally protecting the involved spaces, allowing long-term management contracts and contributing resources

How ‘just’ is hybrid governance of urban nature-based solutions?

Hybrid (or multi-actor) governance has been identified as a key opportunity for upscaling urban nature-based solutions (referred to as urban NBS), representing a demand-driven and cost-effective realization of urban green infrastructure. However it is unclear how such hybrid governance affects the justice outcomes of urban NBS. Through six in-depth cases of urban NBS we show that hybrid governance can lead to both improvements and deterioration of distributional, procedural and recognition justice, depending on the hybrid governance choices. By exploring the tensions between these justice impacts we formulate three main policy implications for hybrid governance settings: the need for transparent decision-making on the distribution of costs and benefits; safeguarding public control over the urban NBS and the use of scientific expertise in combination with bottom-up consultation procedures to recognize both current and future voices

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

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
