The climate crisis repeatedly exposes existing weaknesses in democratic practice.On the one hand, groups that are most affected by the consequences of climate change are often underrepresented in the prevailing political and planning practice. On the other hand, social inequality and the exclusion of people from political decision-making processes increases the loss of trust in political decision-makers and institutions. The new project GUMPI aims to explore possible applications of Citizen Social Science (CSS) in urban development, especially regarding the potential of involving usually underrepresented groups.
