TLDR/Summary

• I attended the 2025 European Urban Resilience Forum in Rotterdam and learned the following:
• There is a resilience blind spot: European cities excel at climate adaptation but miss the bigger picture—climate change is just one of 14 global systemic stresses that could cascade into catastrophic failures.
• Cities like Rotterdam have made advances: Treating cities like accident patients, monitoring vital systems (electricity, water, transport, communications) through cross-sector teams that meet fortnightly, building relationships and understanding system interdependencies.
• War is a resilience killer: Geopolitical conflicts from Ukraine to India-Pakistan tensions are overwhelming political bandwidth needed for long-term resilience planning, diverting resources from preparation to immediate survival.
• New Zealand’s unique challenge: Our geographic isolation could be either shield or vulnerability—New Zealand needs resilience systems that preserve urban functions when global supply chains collapse, not just protection from local weather events.
• We must move beyond simple climate thinking: Nuclear conflict, extreme pandemics, and system-wide failures don’t respect borders—urban resilience must address the full spectrum of global catastrophic risk.
• The bottom line: New Zealand must ensure cities can maintain basic human needs (water, food, energy, communications) post-catastrophe, turning our remoteness into strength rather than weakness.
• A Judging Panel at the Forum concurred that pilot projects are over—we need systematic approaches that seek to change the mechanics of cities.
• Action needs to include cooperation among organisations. At home this might mean NEMA working seriously with the Infrastructure Commission, overseen by Chief Risk or Resilience Officers to build resilient solutions ahead of time.

Introduction

I attended the European Urban Resilience Forum (Rotterdam, June 25-27), which brought together city leaders, policy makers, and resilience practitioners grappling with an uncomfortable reality: traditional approaches to climate adaptation may no longer be sufficient in an era of converging and interacting global risks.

Rotterdam’s vice-mayor discussed life six metres below sea level, while Greek innovation seeks to detect wildfires using AI-enabled drones, and Ukrainian municipal officials are balancing climate action against the immediate demands and effects of war. Discussions at the Forum revealed both the promise and limitations of current resilience thinking.

While many European cities are pioneering innovative climate adaptation approaches, there was also a critical blind spot that New Zealand, given its unique geography and vulnerabilities, cannot afford to ignore: the need to build resilience not just to local climate impacts, but to the full spectrum of global catastrophic and systemic risk and the various cascading and interacting effects that could reshape our world.

The State of Play: Europe’s Resilience Foundations

The Forum’s opening session, featuring a video message from Kamal Kishore of the United Nations Office for Disaster Risk Reduction, established the context that while disaster-related deaths have declined decade on decade, exposure to droughts and seismic risks continues to rise across Europe’s increasingly urbanised landscape. The message was clear, cities house 70% of Europe’s population and face disproportionate climate impacts, but this concentration also presents an opportunity for disproportionate positive impact through targeted urban resilience investments.

Rotterdam’s vice-mayor delivered practical wisdom: we need to make cities green. At six meters below sea level, Rotterdam has learned that green infrastructure—water buffers, reduced concrete, car-free spaces—isn’t just about aesthetics. It’s about heat stress relief, flood management, and public health.

The city’s Roofscape Rotterdam tool allows users to map how 18 square kilometres of roof space could contribute to energy, water management, and other resilience goals, exemplifying the kind of bold and systematic thinking needed.

Our own food system research has recently argued for discussions about land use policy in the context of urban and near urban agriculture for resilience. Similar interactive tools could encourage the public to explore and debate optimal land use policy in New Zealand to balance resilience and development.

A recurring theme at the Forum was multilevel governance with risk ownership at every scale, supported by central government. European officials consistently emphasised the need to move beyond viewing resilience as a cost, instead acknowledging it as essential infrastructure investment that protects people, economies, and existing assets, with figures suggesting every dollar spent on resilience prevents ten dollars in future harm.

The Collaboration Imperative

Although collaboration was spoken of across many contexts, the most innovative and actioned insights came from Rotterdam’s Maarten Nypels who oversees the Vital Urban Systems programme. Maarten articulated both the theoretical and practical dimensions of addressing our current predicament. He observed that “most crises are manmade”, a point that aligns with metacrisis thinking I’ve outlined in my recent blogs. He noted that humanity needs to understand how we created global and systemic vulnerabilities before we can address them effectively. This was a perspective missing from many reactive resilience solutions.

One of Maarten’s practical solutions is transformative: treat a city like an accident patient whose vital signs need constant monitoring. Rotterdam’s Vital Systems resilience program brings together experts responsible for electricity, water, transport, communications, and data systems in iterative fashion. Meeting fortnightly for three hours, these professionals developed deep understanding of system interdependencies and potential cascading failures, understanding each other’s systems. More importantly, they built the relationships and communication channels that enable rapid coordinated response when crises hit.

This model addresses a fundamental challenge in resilience building: breaking down silos and addressing resilience with cross-cutting approaches, agnostic to the specific hazards, whether climate change or otherwise.

Lessons about the Hurricane Katrina recovery efforts presented by Cedric Grant reinforced this. As a Director of recovery, he provided key learnings such as New Orleans developing five microgrid electrical systems to prevent future total power loss, and collaborating with global experts from the Netherlands on flood protection, but also the learning that childcare availability determines whether people can report to work during recovery. The social infrastructure proved as critical as the physical.

The Blind Spot: Systemic risk and polycrisis

The Forum included a session on the current global polycrisis, in which panellists acknowledged the need for holistic approaches, but the discussion fell short of addressing the full spectrum of systemic and global catastrophic risk.

Climate change dominated discussions, despite being just one of 14 global systemic stresses. The holistic agenda needs to encompass disaster risk reduction, systemic risk (system-wide failures), polycrisis (interacting and cascading risks), the underlying stresses generating these risks, and the underlying drivers of humanity’s current predicament. These drivers include human behaviour, and evolutionary and game-theoretic processes subsumed under the moniker of ‘metacrisis’, just as Maarten alluded.

The narrow focus on climate mitigation and adaptation becomes particularly problematic when considering New Zealand’s unique position. A recent Cambridge Centre for the Study of Existential Risk (CSER) paper highlighted the crucial intersection between global systemic risk and global catastrophic risk. Nuclear war, extreme pandemics, and supervolcano eruptions don’t just interact with existing vulnerabilities—their effects can amplify through global systems to produce catastrophic outcomes. These systems include many that are not traditionally considered in climate change mitigation and adaptation thinking.

For New Zealand, this intersection is critical. Our geographic isolation, which provides some protection from certain risks (eg pandemics), also creates unique vulnerabilities.

At the Forum, war emerged repeatedly as a barrier to resilience building, not just in Ukraine, but as a persistent drain on political attention and resources. Politicians are overwhelmed by war considerations across multiple theatres. This must be curtailed if humanity is to ensure resilience to the systemic and catastrophic risk we have created. War is accelerating humanity’s race to the bottom.  

Lessons for New Zealand Urban Resilience Policy

New Zealand needs to consider the full and real consequences of escalating global war, potential global systemic failures, and the other varied hazards, vulnerabilities, amplifying and latent factors that contribute to global catastrophic risk, especially from the perspective of a remote island nation.

As well as asking how our cities can resist the effects of flooding, cyclones, and heat, while reducing emissions, we also need to be investing in ways to prevent disruption due to lack of industrial inputs like fuel, fertiliser and imported spare parts. We should design our vital systems to be self-contained, diverse, and resilient. We need to anticipate the demands of communications in the event of catastrophic internet failure, how to transport and process food with limited liquid fuel, and how to mitigate harmful mis- and dis-information, and a host of other system wide risks.

New Zealand’s resilience planning must extend beyond climate adaptation and economic resilience to address global catastrophic risks. This means ensuring that vital urban systems—electricity, energy, food supply, transport of critical goods—can operate at minimum levels post-catastrophe. It’s more than planting trees or providing heat shelters; it’s about maintaining basic human needs (like water, food, shelter, energy, transport, communications) when global systems fail. Action such as that which Rotterdam is taking, described by Maarten Nypels, was one of the few examples of genuine resilience building across risks that I heard at the Forum.

New Zealand’s new Space Weather plan, developed by NEMA, exemplifies this challenge. The plan focuses on response but it needs integration with the likes of the Infrastructure Commission’s long-term infrastructure plan to ensure that we’re not stuck in cycles of response and recovery, but rather we build out resilient solutions ahead of time. In London response and recovery teams are now co-located with resilience and prevention teams. NEMA must work with the Infrastructure Commission, and consider systemic risk beyond climate adaptation.

Our own report Aotearoa NZ, Global Catastrophe, and Resilience Options lays out one possible vision of extreme risk governance and relevant investment options.

To achieve this upstream investment, finance sessions at the Forum emphasised that investors need detailed plans and predictable contexts. Cities will only be resilient if they’re resilient to the spectrum of Anthropocene risk. For New Zealand, this means building resilience systems that work whether the challenge is climate change, pandemics, or potential Northern Hemisphere nuclear conflict. It means ensuring our remote location becomes a strength rather than a vulnerability.

The conference’s emphasis on Chief Resilience Officers and acceleration of implementation has particular relevance for New Zealand and resonates with much of our previous work, such as our call for a Parliamentary Commissioner for Extreme Risks. Our cities need systematic approaches to resilience that acknowledge our unique vulnerabilities while learning from innovations in Europe and elsewhere.

Judges dispensing sustainability awards at the Forum were clear, that the time of pilot projects is over. Winning entries were visionary, and aimed at changing the mechanics of cities fundamentally.

Conclusions

Much was said and shared at the European Urban Resilience Forum, and I have necessarily focused on just a few themes, namely the need to incorporate an understanding of global systemic and global catastrophic risk in urban resilience programmes.

The Forum demonstrated that the solutions exist, but we need the political will to implement them at scale. For New Zealand, the imperative is clear: we must build resilience systems that address not just the climate crisis, but the full spectrum of global catastrophic risks that could affect our remote island nation.

Perhaps most striking for New Zealand observers is how geopolitical instability emerged as a defining constraint on resilience planning. Ukrainian representatives highlighted the cruel paradox of needing to build climate resilience while resources are diverted to immediate survival. This reality check extends beyond Ukraine—panellists repeatedly noted how global conflicts from Israel and Gaza to Iran to India-Pakistan tensions are overwhelming political bandwidth needed for long-term resilience planning.

For New Zealand, this raises fundamental questions about how our geographic remoteness might be both shield and vulnerability in an era where Northern Hemisphere conflicts, extreme pandemics, or other global catastrophic risks could profoundly impact our resilience assumptions and supply chains. A new wave of resilience action needs to address global systemic and catastrophic risk.
