Part of 1001 Smart Cities — 1,167 documented projects · 🏙️ 10 more in Buenos Aires · 🗳️ Citizen participation guide · 🏛️ Governance projects

From 2017 Buenos Aires ran BA Elige on Consul, the open-source participation platform Madrid released in 2015, letting residents propose and vote on neighbourhood works. The city's own dataset records three editions — 2017, 2018 and 2019 — across which website visits fell from 6.4 million to 1.59 million and winning projects dropped from 443 to 108. Opposition legislators and communal board members argued the programme routed around the comunas, whose consultative councils Ley 1777 gives a role in a budget the city constitution already declares participatory. The platform is now gone: its domain no longer resolves, the last web archive capture is from June 2023, and the city never published a completion record for the projects residents voted for.

Completed 📅 2017–2019

📊 Impact

The one peer-reviewed study of the programme measures what the platform changed about the proposals rather than what got built: analysing the 2018 cycle, Annunziata finds the winning projects tend to be more general than those chosen in face-to-face participatory budgeting, and attributes the shift to the technical possibilities of the institutional design rather than to deliberation among participants. Delivery is unmeasured. The city's own dataset carries no execution or completion field, and the one documented case of a winner not built — a Comuna 5 plaza declared a winner on 21 September 2017 — was removed from the published winners list five days later, the city saying it had no jurisdiction over the land.

🎓 Lesson

A participation platform can document its turnout in fine detail and its delivery not at all — then disappear, taking the record with it.

Analyses the 2018 cycle and finds selected projects 'tend to be more general than in the face-to-face participatory budgeting', attributing the shift to platform design rather than citizen deliberation. Explicitly does NOT measure whether winning projects were built — which is why the entry carries no impact figure.
↗ Nadie Nos Invito — 'Se conocieron las 15 propuestas más votadas del BA Elige y crecen los cuestionamientos'Published 18 July 201718 July 2017. Carries the comunas counterweight: legislator Adrián Camps calls BA Elige 'a way to bypass all the activity of the communes… participatory budgeting managed directly from the executive power without participation of neighbours through communal consultative councils'. Communal representatives Zicolill and Suarez say the mechanism 'can be easily manipulated by political operators'. Supports the bypass claim in the snippet; does not evidence any specific manipulation case, so none is asserted.
