Rewilding the City: Urban Design for Climate Resilience

The Tålö Park project in Malmö, Sweden, completed in 2020, exemplifies urban design embracing climate resilience through rewilding. Designed by SLA, the park rewrites the blueprint for flood-prone areas, combining nature-based solutions with human-centred public space. During peak rainfall, the park collects and stores up to one million litres of rainwater. At other times, it serves as a biodiverse recreational area, inviting residents into a lush urban haven.

This dual functionality reflects a trend in urban design where ecological restoration principles are applied to public spaces. Rewilding encourages natural systems to thrive in their complexity. For cities facing severe climate challenges, rewilding offers environmental and social benefits. By creating spaces that manage urban heat, mitigate flooding, and support biodiversity, designers craft environments that engage communities and redefine well-being.

The urgency to reimagine public spaces has escalated. The Intergovernmental Panel on Climate Change (IPCC) emphasizes that urban areas are at the frontline of climate adaptation. In their 2022 report, the panel identified urban green spaces as critical for managing extreme weather events. Beyond technical functions, these spaces reshape how people interact with their cities. Monika Ständers, a Berlin-based urban ecologist, stated, "The success of rewilding depends as much on social acceptance as on ecological outcomes. People have to see themselves in these spaces—not as passive users, but as participants in a living system."

Examples proliferate globally. In Singapore, the Bishan-Ang Mo Kio Park, redeveloped in 2012 by Ramboll Studio Dreiseitl, replaced a straight concrete canal with a sinuous naturalised river. This project improved flood resilience while creating a biodiverse urban park. In New York City, the Big U proposal by Bjarke Ingels Group envisions a coastal protection system that doubles as a series of interconnected parks, blending climate adaptation with public utility.

These designs contrast sharply with 20th-century urban planning traditions that prioritized cars and concrete over ecological health. They reflect a shift in values—away from domination and towards integration. However, this integration faces obstacles. Funding remains a challenge, particularly in cities where budgets are tight and priorities skew towards short-term gains. Rewilding often conflicts with entrenched zoning laws and perceptions of urban "tidiness."

Maintenance politics complicate the issue. In European cities, wilder landscapes encounter resistance from residents accustomed to manicured lawns. Ständers noted, "People often equate neatness with safety and disorder with neglect." Yet, studies show that biodiverse landscapes can improve mental health and foster social cohesion. A 2021 study published in Nature Sustainability found that urban parks with high biodiversity were rated as more restorative by visitors than those with low biodiversity.

Designers addressing these barriers are experimenting with participatory approaches. The Meadow Project in Sheffield, UK, completed in 2019, involved local residents in planting wildflower meadows in underutilised areas. This co-creation model improved ecological outcomes and strengthened community ties. Rachel Moore, the project's lead designer, stated, "When people are part of the process, they’re more likely to value the result. The meadow isn’t just a design; it’s a collective effort."

Yet, for every success story, there are cautionary tales. The High Line in New York City, often cited as a model for green urbanism, has faced criticism for gentrifying surrounding neighbourhoods. As rents soared, many longtime residents were displaced, raising questions about who these spaces serve. This underscores the need for equity to be central to rewilding efforts. Without careful planning, climate-resilient design can inadvertently exacerbate social inequalities.

In Berlin, a more inclusive example is emerging in the Tempelhofer Feld redevelopment. The former airport, now a public park, has resisted calls for intensive commercial development. City planners are committed to preserving its open character while introducing climate-adaptive features like native plantings and rainwater harvesting systems. This project illustrates how rewilding can align with environmental and social goals when handled collaboratively.

The implications of this shift in urban design extend beyond individual projects. As cities face climate change, rewilding offers a framework that is scalable and adaptable. It calls for collaboration among architects, ecologists, policymakers, and communities—stakeholders who historically operated in silos. This integrated approach is vital for addressing the complexities of urban resilience in the 21st century.

But will rewilding become a widespread paradigm, or remain limited to affluent cities? The answer depends on how cities value resilience—as a cost or an investment. It hinges on public imagination—whether urban residents can embrace wilder visions of their spaces. Ständers remarked, "The city of the future isn’t just built; it’s grown."

For planners and designers, the challenge is clear. Rewilding is not a panacea, but it is a powerful tool for reshaping urban life in the face of climate change. Thoughtfully done, it can transform public spaces into ecosystems where people and nature thrive together. SLA’s Tålö Park demonstrates that these futures are already taking root.
