The term "resilient" has become so popular that we sometimes wonder what it actually means. After appearing discreetly in the field of physics, it is becoming very popular in psychology and personal development. It refers to the qualities of a person who has emerged from great hardship, transformed but not destroyed. Resilience factors include those elements of the environment that enable a person to bounce back or avoid collapse.
But now the metaphor is spreading everywhere: a company can be resilient, a human group and, why not, a city? One might be inclined to be wary.
On January 21 and 22, POPSU organized a symposium to identify avenues for reflection and action. The following article presents a small part of these contributions. In addition to its interesting content, this remote colloquium also impressed by the quality of the images and the fluidity of the transitions.
In the closing remarks of the first day, Cynthia Fleury takes a few seconds to clarify and justify this semantic borrowing. The term "resilience" in this context is a metaphor for approaching the question of large cities and metropolises in an emotional and sensitive way, enabling us to start thinking about what we have an intuition for, what we feel, but cannot yet model.
The commons are those riches that belong to us all, and which must therefore be shared and managed by all. C. Fleury proposes a broad vision. Some commons are negative. For example, waste management must be a collective responsibility. Finally, she evokes the "undercommons". The term designates the bond between people who have been denied access to a resource, and who unite, not on the basis of common ownership, but by the fact that they belong to the community of those who have been excluded.
Alternative communities in collective housing outside any legal framework, or rural areas that have passed through disaster, are human groups forced to invent new organizations, which could well inspire big cities.
Resilience is also based on initiatives, principles of action and shared experience. Cynthia Fleury cites just a few.
1. Soft mobility is a different way of getting around, but also of living together. It's all about low-carbon transport. They include bicycles and energy-efficient public transport, as well as rollerblades, scooters and other equipment that pedestrians in big cities don't find particularly gentle!
2. Positive-energy architecture
3. Green and blue networks. This term describes a continuity of green or wet surfaces, which reconcile a pleasant living environment with the preservation of species. They can exist within an urban framework, or extend over larger areas between towns. The aim is to enable species to live, feed, hide, nest and so on. This approach is the subject of a mooc offered by Tela Botanica in February 2021.
The term is chilling, but the reality is no less so. Collapse modeling determines the point at which a resource is no longer available in sufficient quantity to ensure its equitable distribution. While some authors claim that, faced with this adversity, humans are inventing solutions and sharing rules, Cynthia Fleury believes that the social contract is in jeopardy.
Cynthia Fleury makes the link between the city, the metropolis and the notion of capability, as developed by Amartya Sen and above all Martha Nussbaum.
The list is ambitious. For cities to be resilient, they need to develop resilience factors around individuals.
Rob Hopkins is the initiator of the Transition Towns movement. He proposes a "sundial" of imagination applied to the city. Imagination is the most important ability in the face of a changing and uncertain environment, but it is a collective imagination that unfolds in an urban theater. Imagination therefore needs to be democratized.
The axes of the dial are :
Sabine Barles is a professor at Panthéon-Sorbonne University. She moderated a fascinating round-table discussion on the subject of sobriety. In her opening remarks, she reminded us that sobriety means bringing together extraction, production, consumption and waste treatment.
Gilles Billen, Director of Research at the Université Pierrre et Marie Curie, reminds us that for a long time, Paris lived on food production that extended 150 km around it. Nowadays, the food we eat in our metropolises comes from all over the world. The carbon footprint is enormous. Relocating and reducing animal protein consumption are serious options for the 2050 horizon.
For her part, architect Nicola Delon informs us that most of the waste in a city like Paris comes from construction and public works. Concrete depletes sand reserves and the reinforcements that support it corrode. Concrete's image of solidity and durability is misleading, and restoring buildings based on this material is costly. Nicola Delon proposes a return to bio-sourced materials, such as wood and earth.
Patrick Boucheron provides a historical perspective. A specialist in the Middle Ages, Italian cities and the history of power, he gives us three versions of urban structures, which can shed light on the problems of contemporary metropolises.
Florence is a powerful and attractive city, with a high concentration of power figures. "It dominates its rivals Siena and Pisa, but does not crush them," says the historian. It's a model of intercommunality: all the cities interact, but none is powerful enough to stifle the others.
Naples, on the other hand, appears according to Boucheron as a voracious, predatory capital that cannibalizes its neighbors to the point where none can claim to be its rival.
Another model exists. That of Northern Italy. Milan is a metropolis that organizes its domination in a structured way.
According to Patrick Boucheron, "for a long time, Italy was a country of cities, and because it was a country of cities, it was resistant to the nationalization of power". Centuries later, metropolises still appear as spaces of resistance, of counter-power to the State.
In the United States, when the head of state was denying global warming, the major metropolises proved capable of inventing solutions and mobilizing jointly.
These few insights, which do not capture the richness of the two-day conference, call for a multi-disciplinary analysis of resilience. They also show that there is still room for optimism, for action and for the commitment of players from different horizons.
Researchers, politicians and technicians have been able to tackle the issues in a spirit of listening and imagination.

The confirmation bias that prevents us from thinking
Those of you who follow public debates, particularly online, will have noticed that things sometimes flare up very quickly. Arguments are met with insults, and facts are criticized as false. So what's going on? Scientists know what's going on, and it's not a pretty picture: we have biases and fundamental opinions that are extremely difficult to change.
Convincing parents of new pedagogical and technological approaches
When the time comes to integrate a new teaching approach or technological tools, it's important not only to enlist the support of the school management, but also that of the students' parents. Indeed, the latter can quickly rise to the barricades if they feel that their child is a didactic lab rat. To avoid confrontation, teachers need to make their project clear from the outset.
Why bother teaching cursive handwriting?
In an age when most written communication takes place on digital media, it seems odd to continue teaching children to write in cursive or script. At a time when Americans are gradually abandoning this form of teaching, why should handwriting be retained in schools? For many reasons, say researchers and education experts.
When language and politics don't mix
Are language, nation, culture and politics related? Can one change one's language to enhance one's self-worth? How has the impact of colonialism affected the cultural and linguistic identity of nations?
