What is resilience? Well, there is no simple answer to this. Especially not regarding a city’s ecosystem. The concept, you might say, is in development across different sciences and has recently entered the public governance domain related to society’s social-ecological system.

Can resilience be measured as an indicator of an ecosystem’s state? How are the living and non-living factors of the measured system calculated? Can it create true insight into the tone of the city, society, and nature?

Resilience is the new buzzword among public leaders and managers, but it has played an essential role in natural ecosystems for millions of years. It was launched in 2013 with 100 Resilient Cities as a relatively new concept of thinking and acting from the government’s perspective. But what is it about? The ability to endure stress and still perform, or the capacity to recover after a catastrophe? Maybe both.

The question cannot be answered, or is meaningless, without putting it in the context of resilience of what to what? In our approach, we focus on the resilience of the ecosystem city to specific external factors (abiotic, climate change) or internal factors (biotic, virus attacks) that cause disturbances.

“Resilience has multiple levels of meaning: as a metaphor related to sustainability, as a property of dynamic models, and as a measurable quantity that can be assessed in field studies of socioecological systems (SES). The operational indicators of resilience, however, have received little attention in the literature. To assess a system’s resilience, one must specify which system configuration and which disturbances are of interest.” – Carpenter et al. (2001)

Holling (1973) introduced the term resilience into the ecological literature to help explain the nonlinear dynamics observed in ecosystems. Since then, the concept has diversified in all directions. Resilience is widely interpreted and used; it is a difficult-to-understand concept and, therefore, possibly of limited use for precise diagnosis and related public governance. Like accountability, the new normal, alignment, roadmap, risk, streamlining, and sustainability, it can become a container or a buzzword.

“Resilience,” like love, is difficult to define, yet everyone – from United Nations Secretary-General Ban Ki-moon to government agencies, company boards, and community groups – is talking about how to build or maintain it. So, is resilience a useful concept or a meaningless buzzword? – Brian Walker (2015)

We might return to the forest for the core definition of resilience. It is simple and, therefore, generally applicable.

‘Resilience is the ability to bounce back, basically in the face of disturbance, maintaining functions and structures of the system and recovering from the disturbance.” – Rupert Seidl (2019)

The resilience of the ecosystem city tells the story of the population’s balancing act within its present habitat. Of course, there are many layers of habitats within the city, and some justify zooming in to consider resilience at a lower level. In general, it is like when you plan to invest your money in stocks and funds: past results are no guarantee of future performance.

Resilience is like looking in the mirror: you know where you are and where you come from, not so much where you are going or what will happen. It is hard to predict how future internal and external developments will influence communities’ habitats, whether they will exceed the system’s resilience, and whether the system can adapt to change effectively.

To successfully introduce resilience into public governance, Brian Walker (2017) of the Resilience Alliance underlines the (urgent) need for this—it is wise to start by using it always in the context of the resilience of what to what (Carpenter et al., 2001). Much work remains to bring resilience into the public domain. The first steps are there.

One thing stands out. Measuring resilience can help determine the tone of a city, society, and nature. But it is very complex. For that, it has to develop further towards a more complete and refined concept. The “of what to what” question has to be built in. We are on our way.
