2008–2012 · The installation
The Unidade de Polícia Pacificadora model was pioneered at Santa Marta favela in November 2008. The model: Rio state-police BOPE (special operations) units would enter a favela, secure it from trafficking-organization control, and then install a permanent community-policing UPP with regular officers who lived and worked in the neighborhood. Cantagalo- Pavão-Pavãozinho-Vietnã was designated for UPP on 23 December 2009.
The early years were genuinely transformative. By mid-2012 Pavão-Pavãozinho's recorded unemployment had dropped to approximately 5% (from much higher baselines); residents reported freedom of movement they hadn't had in decades; municipal services (garbage collection, water, electricity) reached the upper reaches of the favela for the first time; community tourism initiatives launched. The federal government's 2011 Plano de Aceleração do Crescimento (Growth Acceleration Plan) directed substantial infrastructure investment into the pacified favelas, including the Plano Inclinado project.
2013–2016 · The high water
The Rio 2016 Olympics preparation drove a massive round of UPP expansion through 2013–2015; by the Games, 37 UPPs covered approximately 1.5 million Rio residents. International coverage of the program was broadly positive through this period. Academic analysis was more mixed — scholars pointed to uneven enforcement, tensions with residents' customary autonomy, and specific incidents of police violence (notably the April 2014 killing of dancer Douglas Rafael da Silva Pereira in Pavão-Pavãozinho) that triggered community protests.
2017–present · Decline
Rio's fiscal crisis of 2016–2018 — a state-level budget collapse driven by falling oil royalties, the 2016 impeachment of Dilma Rousseff, and the federal austerity that followed — led to severe cuts to the UPP program. Officers went unpaid for months at a time in 2017–2018; posts were reduced in staffing; some were abandoned entirely. Trafficking organizations returned to de facto administration of several favelas. As of 2026 the UPP in Cantagalo-Pavão-Pavãozinho-Vietnã is nominally operational but substantially degraded; the exact status fluctuates and residents report effective conditions that vary by street and by week. The community is safer than it was in 2008 but meaningfully less safe than it was in 2012.
The honest frame: the UPP program was an unfinished experiment. It produced real short-term gains in specific communities; it depended on funding and political will the Rio state could not sustain past its first decade; its long-term legacy is ambiguous. The community's own assessment varies sharply by age, by position, and by which week you ask.
