Porto Alegre invented participatory budgeting in 1989, and hundreds of cities copied it — which makes it the rare atlas city best known abroad for something it has spent two decades dismantling at home. Its assemblies stopped taking new demands after 2016 and were revived in 2022 on a reserve the city council sets rather than the citizens.
