Morning Coffee – Greycells Thursday, 19 March 2026, 10:00–12:00 Club Suisse de la Presse Château de Penthes, Genève (Bus 20 • Parking available)

Hosted by Greycells, with Guest Speaker Diane Henny

Growing the City: How Micro-Forests and Edible Forests Can Regenerate Urban Life

Imagine rooftops turning into jungles, courtyards into tiny forests and office façades producing salad instead of just casting shade. That is exactly what Diane Henny and TSF UrbaNature are doing in Geneva, and Greycells invites you to come and see how.

During this Morning Coffee, Diane will take us on a tour of Miyawaki micro-forests, edible forests and urban agroforestry projects that cool overheated streets, bring back birds and pollinators, grow food close to home and even boost mental well-being. These are not decorative plants in pots, but living infrastructures that store carbon, regenerate soils and turn “empty” roofs, courtyards and schoolyards into vibrant miniature ecosystems.

Diane is a specialist in cultural mediation, psychology and corporate social responsibility, and co-founder and CEO of TSF UrbaNature, a Geneva-based NGO dedicated to regenerating and renaturing urban environments since 2016. Working with the City of Geneva, universities, companies and citizens, TSF UrbaNature transforms rooftops, façades and ground-level spaces into thriving habitats for biodiversity, local food and climate resilience.

Diane will lift the curtain on the governance and partnership models that make these projects possible: how NGOs, public authorities and private actors can team up to redesign the city as a living organism rather than a concrete machine. This is not “just” about planting trees; it is about reimagining urban life, one micro-forest (and one coffee) at a time.

Join us, bring your questions (and your inner gardener), and leave with practical inspiration for how cities can become greener and cooler (and your mornings tastier and pleasanter with Greycells friends - coffee, tea & pastries included). A cash donation from non Greycells members to offset part of the costs would be much appreciated.

We need to know how many people are coming, so please confirm your participation by e-mail at greycells08@gmail.com

March 2026 Greycells Café Morning Rewilding the City from the Rooftop

What if the future of urban resilience is right above us — on our rooftops? In this Café, Diane Henny — permaculture expert, transcultural researcher, and co-founder of Terrasses sans Frontières — invites us to explore how rooftops can be reimagined as living ecosystems. Her work blends environmental know-how with human psychology, showing how green roofs foster biodiversity, social connection, and mental well-being.

Open to All

Greycells Morning Cafés are a quarterly opportunity to mix minds, swap stories, share insights, and build community. Whether you're a member, a guest, or just curious, come as you are—and leave with more than you expected. And of course, coffee and cake—because no matter how long you live, some pleasures should remain timeless.

KNOWLEDGE SHARING

What happens to a lifetime of experience when the job ends?

At Greycells, we believe it shouldn’t be relegated to oblivion — it should be shared.

Our members bring decades of international experience — in diplomacy, development, health, labour relations, climate sciences, trade negotiations, project leadership, and team management. Some are subject-matter experts. Others have mastered the art of connecting across cultures, resolving tensions, and negotiating with insight and humility in complex political settings.

Sharing this knowledge is not about teaching from a podium. It’s about dialogue — offering context, asking the right questions, and guiding emerging leaders as they navigate their own paths. For the mentee, it’s access to hard-earned wisdom. For the mentor, it’s the deep satisfaction of relevance — of seeing one’s lived experience spark meaning again.

At Greycells, knowledge sharing isn’t a transaction. It’s a continuation — of purpose, of service, and of the bonds that make international work more human.

BUILDING BRIDGES

We don’t build physical bridges.

We build human ones — across cultures, generations, expectations. And between local and international Geneva.

As international civil servants, many of us lived and worked in global institutions — sometimes at the centre of big decisions, but often within their own perimeters: defined by protocol, insulated by mission, and distant from local life. Now, in retirement, we find ourselves equals among equals — citizens again — but still often seen as “different.” Building bridges means closing that perception gap.

We bring lived knowledge of cultural nuance, institutional dynamics, and the habits of negotiation — not just across borders, but across mindsets. We’ve learned how to work with difference. Now we help others see that many of those differences are imagined or misunderstood.

Our role is not to impose insight, but to invite exchange — to make experience visible, and to make institutions more relatable. Whether it’s connecting students with Geneva’s multilateral story, collaborating with community initiatives, or joining local conversations as global citizens, our bridge-building is both civic and deeply human.

BELONG AND CONNECT

After a life of purpose and professionalism, what many of us miss most is the meaning — and meaning often returns when we meet others who understand.

Not formal meetings, but encounters: a shared glance of recognition, a conversation where no explanation is needed, a moment where someone just “gets it.”

That’s what Greycells offers: not just activities, but connection.

A way to stay in rhythm with others who’ve lived across borders and mandates, who’ve navigated both institutions and ambiguity — and who now seek companionship, not hierarchy.

You don’t need to prove anything. You don’t need a plan.

You just need the curiosity to be among peers — to share a coffee, a story, a perspective, or a question.

It’s the encounter of kindred spirits: a space of mutual recognition, where experience still finds resonance, and where new friendships grow naturally from shared outlooks.

Belonging doesn’t have to be loud. Sometimes it’s just knowing that when you show up — someone understands.
