In this article, I discuss São Paulo's legal apparatus in respect of environmental noise. I begin by situating my analysis within broader citizenship issues. I then focus on three debates on noise control in the city. The first two debates involve noise ordinances created in the 1990s and enforced by São Paulo's Programa de Silêncio Urbano (Urban Silence Programme, PSIU). The first revolves around the evangelical lawmakers’ attempts to exclude, minimize or hinder the impact of a noise ordinance on religious services. The second debate focuses on an ordinance that required bars without acoustic insulation to close at 1 am – a demand that faced strong opposition from businesses involved in the night-time economy. The third debate describes the recent attempt of a group of acoustic engineers to lobby the city administration for the systematic mapping of traffic noise. I contend that environmental noise is a fruitful point of entry to investigate how the state mediates universal equality and individual freedom, welfare principles and economic gain.

This article argues that the prepaid energy system put into operation in Medellín and across Colombia worked as an expression of ‘energopower’; that is, energy as a means to govern societies. The article uses press archives and company statements, official statistics and group interviews to show how energopower operates in Medellín along three lines: that Empresas Públicas de Medellín, the city's public utility company, encouraged disconnected and displaced people as new buyers of prepaid energy services instead of citizens entitled to those services; that the implementation of the prepaid energy system coincided with the vertiginous capitalisation that allowed the city to fund its ‘Social Urbanism’ and EPM to expand operations across Colombia and other countries in Latin America; and, that prepaid electricity as a tool of energopower subjugated displaced and disconnected populations to new forms of affordability that prompted barrio women to understand and oppose its disciplining methods of domination.

In this article we argue that the pacification of strategic Rio de Janeiro favelas is a case of what David Harvey calls accumulation by dispossession, allowing for capital accumulation at multiple scales. Drawing on multi-year participant observation, we seek to show the particular form that this process takes as it works through Rio's social and spatial structures. Unlike the mass removals of the 1960s and 1970s, favela families have more recently been displaced through a process of thinning, in the context of a neoliberal development programme centred on a series of mega-events. Removal is carried out through a combination of threats, promises, disinformation, and the intentional generation of insecurity that together constitute a form of psychological terror.
