According to Forbes, the smart-city model is hitting its limits as a new paradigm called regenerative urbanism emerges to redefine how developers, investors, and civic leaders measure value. The approach treats cities as living ecosystems that can heal nature, rebuild communities, and sustain long-term value, with Tokyo Tatemono and the Future Food Institute launching a Regenerative Cities Manifesto that calls for cities to unite urban and rural systems across six domains of renewal. The built environment accounts for nearly 40% of global emissions and more than $300 trillion in asset value, while UN-Habitat’s World Cities Report 2024 estimated cities will need $4.5-5.4 trillion annually through 2030 to build climate-resilient infrastructure. This philosophical shift from sustainability to regeneration represents a fundamental rethinking of urban development priorities.

The Limits of Technological Solutionism
The smart city movement, which dominated urban planning for two decades, operated on a flawed premise: that complex urban challenges could be solved through data collection and system optimization. This technological solutionism failed to account for the organic, unpredictable nature of human communities and ecological systems. Cities aren’t machines that can be fine-tuned for efficiency—they’re complex adaptive systems where interventions often produce unintended consequences. The 2025 study in Nature Humanities and Social Sciences Communications revealing China’s mixed results with smart-city policies demonstrates this fundamental limitation. When you treat people as data points rather than participants, you create efficient but sterile environments that lack the social cohesion necessary for true resilience.
The Implementation Gap: Why Regeneration Is Harder Than It Sounds
While the philosophy of regenerative urbanism is compelling, the practical implementation faces significant structural barriers that the source article only hints at. Most city governments operate in departmental silos with separate budgets, mandates, and success metrics. Regeneration requires cross-departmental collaboration that most municipal structures actively discourage. The funding mechanisms for traditional development—which prioritize clear ROI timelines and measurable outputs—are poorly suited to regenerative projects where benefits may take decades to materialize and are difficult to quantify. Even the UN-Habitat’s estimated $4.5-5.4 trillion annual need for climate-resilient infrastructure assumes we can simply scale existing approaches rather than fundamentally rethinking how we finance and govern cities.
The Century-Scale Investment Dilemma
Tokyo Tatemono’s claim of planning investments on “century-scale horizons” represents both the promise and the peril of regenerative urbanism. While visionary, this approach conflicts with the quarterly earnings pressures facing most publicly-traded companies and the political cycles that constrain municipal leaders. The $6 trillion in sustainable finance instruments mentioned represents progress, but most green bonds still fund incremental improvements rather than truly regenerative systems. The real test will be whether institutional investors—who control the majority of real estate capital—can be persuaded to accept lower short-term returns for uncertain long-term benefits. The regenerative design frameworks being developed by firms like Arup provide useful tools, but they don’t solve the fundamental misalignment between regenerative timelines and conventional investment horizons.
The Cultural Work of Regeneration
The most challenging aspect of regenerative urbanism isn’t technical or financial—it’s cultural. As Sara Roversi correctly notes, “Regeneration starts with relationships.” This requires a fundamental shift in how we conceive of urban citizenship, moving from consumers of city services to stewards of urban ecosystems. The Kyobashi Living Lab’s focus on food as a connector represents an interesting approach, but scaling this from pilot projects to city-wide transformation demands changes in education, governance, and social norms that typically take generations. The success of initiatives like Amsterdam’s adoption of Doughnut Economics principles suggests this is possible, but these remain exceptions rather than the rule.
A Realistic Path Forward
The transition from smart to regenerative cities won’t happen through manifesto declarations alone. It requires new governance models that break down departmental silos, innovative financing mechanisms that align with long time horizons, and metrics that capture regeneration’s full value beyond conventional economic indicators. The $2.3 trillion market valuation for urban regeneration by 2033 suggests commercial potential, but this growth could easily be co-opted by greenwashing if clear standards aren’t established. The most promising aspect of this movement is its recognition that cities must work with, rather than against, natural systems—but turning this philosophy into practice will require overcoming decades of entrenched thinking and institutional inertia.
