Cities Reimagined

Reimagining Ghent: From grey to green.

What does it really take to bring nature back into a dense and growing city?

In this episode, we return to Ghent and the European Urban Initiative project REWILD. The project is not simply about removing asphalt or adding more greenery. It is an attempt to change the rules, routines and relationships that have made soil sealing the default way of building cities.

Johannes speaks with members of the REWILD project about the project’s first year of experimentation. They discuss working with residents and businesses, creating space for nature on public and private land, and addressing the institutional barriers hidden beneath Ghent’s ambitions.

Because breaking up the asphalt may be the easy part. Lasting change also means questioning established standards, balancing competing interests and finding ways to turn individual experiments into a new way of working across the city.

In this episode:

• Why is desealing much more than a technical challenge?
• Which rules and routines prevent cities from making space for nature?
• How can residents and businesses become part of urban rewilding?
• What can cities learn from small experiments in streets, courtyards and brownfields?
• How can REWILD help make desealing the new normal across Ghent?

What happens when a city looks beneath its streets for answers to the climate crisis?

Bruges may be famous for its canals, but water did much more than create the city’s postcard views. It helped turn medieval Bruges into one of Europe’s largest and most internationally connected cities.

Beneath today’s streets, parts of that historic water system still survive. Ancient pipes continue to carry water. Medieval wells are rediscovered during construction work. One was found when the city tried to plant a tree.

Could this forgotten infrastructure help Bruges prepare for drought, heavy rainfall and a changing climate?

For this episode, I sit beside the canals with Ilse Vansevenant and city archaeologist Frederic Roelens from the City of Bruges. Tourist boats pass as we explore a water story spanning more than 700 years.

We talk about the network that once supplied “medieval Manhattan” with fresh water, why residents knew exactly which well provided the best water for peas or tea, and how one of these wells could soon help people water their plants again.

But this is not only a story about the past. Ilse explains how sensors are helping the city understand groundwater, water quality and the needs of individual trees. Together, we explore what happens when archaeology, climate adaptation and new technology meet.

In this episode:

• How can a seemingly water-rich city prepare for both drought and flooding?
• What can Bruges’ medieval water infrastructure teach us about climate resilience?
• Could ancient underground water pipes be brought back into use?
• How can sensors reveal when individual trees need water?
• How can archaeology become an opportunity for urban innovation?
• Why are citizen ownership and experimentation essential for living with water?

What turns a space into a place?

Vivian is an urban planner, geographer and board member of Placemaking Europe. For her, placemaking is more than activating a square or adding colourful furniture. It is a mindset that brings communities, public authorities and professionals together to rethink how shared places are used, experienced and cared for.

What happens when a city turns back towards the water? And what do we lose when public space becomes too controlled, too polished or too predictable?

With Vivian, I talk about Thessaloniki’s rediscovered waterfront, hidden water beneath Athens and why a little friction and chaos might actually be good for urban life.

We also get into the bigger questions: climate change, privatisation, democracy and the pressure on the people trying to change cities. Because placemaking is not only about transforming places. It is also about how we relate to them, to each other and to ourselves.

IN THIS EPISODE:

• Why placemaking is about more than attractive public spaces

• How cities can reconnect people with water and nature

• Why friction and messiness are part of healthy urban life

• How public space supports participation and democracy • Why placemakers also need places of care

Reimagining urban swimming

What does it take to transform a former industrial dock into a place where people can safely swim?

In this episode of Cities Reimagined, Johannes visits the Keerdok in Mechelen, Belgium. Once dominated by warehouses, parking and industrial activity, the area is being transformed into a new urban neighbourhood that opens the city towards the water as part of the 'Water as the Source of Urban Public Space' Innovative Action funded by the European Urban Initiatives.

He speaks with Sander Belmans from De Vlaamse Waterweg and An Schepers and Barbara Enckels from the City of Mechelen about the long process behind the city’s open-water swimming zone.

After five years of temporary experiments, Mechelen is now preparing a permanent swimming facility at the Keerdok. The new design will combine swimming infrastructure, public space, shade, greenery and floating habitats for animals and plants.

If you have ever been to Bruges, or seen it in films or photos, chances are you have noticed at least one of the following: canals, swans, water, tourist boats. What often goes unnoticed is that Bruges, and the wider region of Flanders in Belgium, regularly suffers from droughts.

In this episode, we meet Astrid Stroobandt from the City of Bruges and Simon Thys from the non-profit organisation Waterland, who are currently running the Blue4Green project, an Innovative Action funded by the European Urban Initiative. Astrid and Simon explain how the project aims to change the city’s relationship with water in multiple ways, and how children’s dreams can inspire change just as much as data and technological innovation. We also hear how the city is experimenting with medieval infrastructure as water buffers, and how green and blue algae are cutting summer fun short.

I have to start with an apology. To the guest of this episode, Kristijan Radojcic. After we had this conversation in a wild hotel room with tacky wallpaper in Wroclaw, Poland, the raw version of the recording was sitting unedited on my notebook for much too long.

Finally, I am more than happy to share this episode with you, where Kris takes on a deep dive into his childhood in Slovenia and how a trip to Southeast Asia changed everything.

If you are around urban EU programmes, you might have bumped into Kris on various occasions as he is working with URBACT, a programme that helps cities to develop an integrated set of actions for sustainable change. He and his family live in Paris.

Connect with Kristijan and Johannes on LinkedIn and take a look at URBACT.

Why does neighbourhood-level community matter for urban resilience?

Do you remember the first time you learned how to ride a bike? Chances are that you do, and if you kept on kicking those pedals, you might have some fond memories about the (daily) adventures with your bicycle. But… although biking ticks almost all boxes when it comes to urban sustainability, health, livability, affordability and accessibility, our cities still do not unfold the full potential of how urban biking can make our neighbourhoods better places.

My guest today, Josip Rotar from the Maribor Cycling Network, is one of those who pushed for change in the city. Find out how advocacy for urban biking led Josip to take a political role and why urban biking is competing with the SUV of your neighbourhood (or your own?).

Urban rewilding is more than planting trees. It’s about reshaping cities by de-sealing land and inviting nature back in. In this episode, we head to Ghent to explore REWILD, a bold project funded by the European Urban Initiative that breaks up concrete, engages residents, and creates space for ecosystems. With Linde Vertriest and Annelies Sevenant, we talk about the barriers and challenges and touch upon the 1 Mio dollar question: what does it take to rewild a city?
