In rapidly growing cities the evolution of utility and communication infrastructures has enabled the creation of ‘premium networked spaces’ exclusively for wealthier groups thus deepening already large social inequalities. By the same token, in a context of spatially concentrated income-earning opportunities and other urban functions, as well as limited purchasing power, accessibility to adequate means of connectivity with the rest of the urban fabric can be a determining factor in overcoming conditions of poverty for residents in physically marginal areas. Within the framework of the splintering urbanism thesis, and using the case study of Soacha, a municipality adjacent to Bogotá, Colombia's capital city, we examine the apparent mismatch between the growth of low-income informal settlements in peripheral locations and the development of transport networks in the period 2000–2010. Our aim is to identify the effects on social and spatial marginalisation of an uneven provision of material infrastructures and services for mobility. We identify central elements in the structure of the networks of connectivity between Bogotá and Soacha, highlighting the main gaps that lead to a fragmented set of connections. We develop a set of criteria for planners and policy makers searching for a more informed analysis of transport supply and policy development practice for poor peripheral populations in similar regions and contexts.

With the consolidation of democratic governments in the 1980s and 1990s, wholesale evictions of entire neighbourhoods ceased to be a solution to urban problems in Latin America. This paper discusses an example of a new generation of municipal programmes aimed at physically upgrading informal settlements while integrating them both physically and socially into the fabric of the city. In Medellín, a city with a recent history of violence and social inequality, the audacious use of well-established ski-slope aerial cable-car technology in dense and hilly low-income informal settlements was followed by major neighbourhood upgrading comprising new social housing, schools and other social infrastructure, as well as support to micro-enterprises. Although lack of mobility contributes to social inequality and poverty, the paper argues that the introduction of quick-fix highly visible transport technology on its own is unlikely to help reduce poverty. Although urban upgrading programmes and the symbolic value of cable-car systems have instilled among the local population a feeling of inclusion and integration into the ‘modern’ city, they can also be understood as mechanisms for the ‘normalisation’ of informal sectors of the city.

During the past decade, the political culture of Bogota's citizens has undergone a major transformation. Whilst during decades the inhabitants of the Colombian capital could barely hope to be taken into account by the city's mayors in their administration, today most citizens will expect to see the effect of their vote and at least some of their aspirations in the actions of the head of the local government. In this article we review the work of the city's mayors in the four decades between 1961 and 2000. Our aim is to reflect on the main factors that helped shape the administration of the 21 mayors who held office during that period. [ABSTRACT FROM AUTHOR]
