To keep the earth a liveable planet and to stop climate change, system changes are needed . Getting people moving and empowering them to act sustainably is therefore crucial. Also ensuring an inclusive approach so that sustainable behavior change is possible for everyone! Important models addressing this urgent matter are Kate Raworth’s Doughnut Economics and Marleen Stikker’s Public Stack.

You can attend this event physically or online. When making your reservation, choose between a physical spot or an online reservation.

But how do we make ideas like the Doughnut model and Stacktivism possible in Amsterdam, the Netherlands and beyond? Regenerative, Circular and sustainable cities require that we understand “Ownership” differently. This requires for new ways of imagining, questioning, and connecting. Which methods do we need to redesign our current processes and economic models?

In this program Marleen Stikker and Kate Raworth will give you insights to their models, and will reflect on some great innovative initiatives/ projects/ ideas that we discuss with other speakers. We invite you to join this session and see if we all can come-up with ideas to redesign ownership!

Lyongo Juliana fell in love with Architecture when he was a student in Architectural Engineering at TU/Eindhoven. During his Architect in Residency at ARCAM Architecture Centre Amsterdam, he investigated the degree of diversity and inclusiveness of architecture in Amsterdam. The outcome of his research: ‘We need to pay more attention to the end-user, regardless of ethnicity.’
Last year Lyongo was the first fellow of the Designing Cities for All project.

Sascha Glasl studied architecture at RWTH Aachen, graduated cum laude in 2007 and co-founded Space&Matter in Amsterdam in 2009 at the height of the economic crisis, creating projects when opportunities were scarce. Equally passionate about strategic design, innovative concepts and democratic development processes, Sascha focuses on implementing the principles of the Doughnut economy in the built environment. He initiated De Ceuvel and SWEETS Hotel, and played a leading role in shaping the plan for Schoonschip. He is currently exploring how Community Land Trusts in particular can accelerate this transition and focused on creating a comprehensive ecosystem that can increase the scale and impact of these past projects and achieve circular area development.
