Experimenting for sustainability transitions: A systematic literature review

This review paper systematically queries the Sustainability Transitions literature to unpack the concept of 'experimentation'. We define an experiment as an inclusive, practice-based and challenge-led initiative, which is designed to promote system innovation through social learning under conditions of uncertainty and ambiguity. A distinction is made between various terms (niche experiments, bounded socio-technical experiments, transition experiments, sustainability experiments and grassroots experiments), each with their own theoretical backgrounds and discursive and empirical focal points. Observed patterns and trends in the literature are discussed, as well as promising lines of enquiry for further exploration of- and a reflection on experimenting for sustainability transitions in the context of the welfare state.
