The Design of Nature-Based Solutions: Learning from Practices of Regenerative Transformation

Abstract

Nature-based solutions (NBS) have gained popularity within mainstream sustainability research agendas due to efforts to coordinate global responses to urban sustainability challenges. Their potential is promising: by applying an ecosystem services approach inherent in NBS to urban development, they simultaneously provide social, economic, and environmental benefits, and they help operationalize regenerative urban development. Urban NBS are diverse in scales and forms (from green belts to urban parks at the macro scale or rain gardens at the micro scale). As NBS, these green solutions are portrayed as means to the use of the urban environments’ capacity to deliver ecologically sound and socially desirable outcomes not only with but for nature. Still, at present, urban NBS are often temporary, fragmented, and used in an ad-hoc way. One of their major criticisms is that realizing NBS in practice can be detached from their theoretical promise. As a result, NBS can deliver below their actual potential, limiting their contribution to the challenge of urban transformation. Delivering below potential is intricately connected with the way urban spaces are designated and designed, reflecting user practices, culture, and lifestyle, and the understanding that NBS must serve humans and the natural environment alike. This dissertation explores the mutual interplay between NBS and the ‘designed’ features of the urban environment: how NBS can be amplified through strategic design considerations and enhance the ‘urban’ with human well-being as its integral part. I examine the design of NBS to understand the consequences of applying specific design frameworks and argue that a broad range of design factors affect their application and potential impact on regenerative urban transformation beyond sustainability. I apply Mang and Haggard’s (2016) ‘three lines of work’ tool to construct a holistic design framework that represents critical dimensions that influence the creation and implementation of NBS for urban transformations. It was intended to guide design projects to develop regenerative synergies within their immediate and larger context. The ‘three lines of work’ comprise the ‘spheres of influence’ of a design project exerted across three dimensions: 1) the motivations behind the actions (design approaches), 2) the capacity and capability of the community to deploy the project (design processes), and the contribution to the regenerative capacity of living systems (design outcomes). Through a multidisciplinary case study analysis, the research highlights the role of design in conceptualizing, adopting, and implementing urban NBS and how the critical design dimensions influence these efforts in making their regenerative potentials happen. Qualitative, empirical evidence is gained from nine case studies in three cities (Győr, Hungary; Milan, Italy; and Melbourne, Australia). Through this assessment, I demonstrate the relevance of the interconnected design dimensions for embedding NBS into urban environments, thus, affording a transformed urbanity with different experiences, usages, and actions. Furthermore, by exploring the design framework of NBS, I provide a systematic and critical reflection on current urban design-based placemaking practices. I argue that a radical repurposing of the urban space is necessary where streets, buildings, homes, and open spaces can be redesigned into regenerative, living ecosystems.
