Budgeting, i.e., the allocation of money or other sparse resources to specific projects, is one of the key decisions any political body or organization has to take. Participatory budgeting was developed in the 1990s in Porto Alegre, Brazil, as a method for making such decisions in a more democratic way, by putting the selection of projects to be funded to a vote. It has found rapid adoption worldwide, in particular at the municipal level. Nevertheless, it is still a comparatively new tool for democratic decision-making and many questions about its benefits and drawbacks as well as the best way to implement it remain open. Our meet-up offers a chance to discuss these questions with leading researchers from various disciplines and with practitioners that bring participatory budgeting to life in their municipality.
