Pertinence of Consolidation or Relocation of Buildings in Settlements in Lambaré, Paraguay.

Abstract

One of the fundamental issues in neighborhood improvement processes refers to the tension that exists between consolidating housing generation efforts driven by the communities, and the sometimes imperative need to suggest the relocation in proximity of housing that faces high degrees of precariousness or exposure to environmental risks. This article discusses how methodologies based on the use of free software and collaborative methods make it possible to elaborate base cartographies and highly detailed characterizations of precarious settlements, from which it is feasible to point out which buildings of a community have greater potential for in situ consolidation, versus those that have a profile that indicates the need for relocation. In this way, the article aims to provide a replicable method that contributes to the work of academics, communities and local governments involved in slum upgrading projects.
