The material in this podcast looks at sustainability in a context of grassroots innovation and degrowth. Grassroots innovations are community-driven approaches to sustainability, while degrowth promotes the transformation of societies and economies to ensure environmental justice and a good life for all. In this podcast we discuss with Ruby van der Wekken, a member of the global justice movement. She has experience of being involved in many different community-based grassroots innovations, such as the Finnish Time Bank. During the last years, she is engaged in running the cooperative OmaMaa in Tuusula. In the podcast, Ruby talks about how she started working in grassroots innovations, about OmaMaa and its strategic partnerships, and about future opportunities and challenges. More information about the OmaMaa co-operative can be found here: https://www.omamaa.fi/in-english/ This podcast was produced as a final group assignment in the course Sustainable Organising in Times of Crises at Hanken School of Economics in the spring of 2024.
