Instrumento de apoio à tomada de decisão para estratégias locais em programas de habitação de interesse social baseado em princípios da economia circular

Abstract

Unplanned urban growth and escalating climate emergencies pose critical challenges to the promotion of social housing (SH), requiring solutions that integrate social justice and environmental sustainability. This thesis investigated how the principles of the circular economy (CE) can guide the definition of strategies for advancing HIS in Curitiba, Paraná, Brazil, while ensuring their applicability across diverse urban contexts. The research adopted the multipaper approach, that is, peer-reviewed articles were developed and published in highimpact international journals. These publications led to the formulation of a general strategy matrix for SH based on CE principles, comprising 32 strategies organized in thematic clusters. Designed as a decision-support tool, the matrix was applied and validated through a case study in the city of Curitiba, involving key stakeholders from the housing sector. The analysis combined semi-structured interviews and secondary data to assess the technical, legal, economic, and social feasibility of the proposed strategies. The findings revealed that 10 strategies are immediately feasible, while 17 are feasible under specific conditions, such as financial investment or regulatory and cultural adaptations. Furthermore, the research provides concrete tools for assessing the practical feasibility of the previously conditioned strategies. The practical application of the matrix demonstrates its utility as an analytical and decisionmaking instrument, supporting the context-sensitive selection of circular strategies in the field of SH. The research thus fulfilled its objective by providing a validated and replicable methodological contribution towards more sustainable, socially inclusive, and ecologically responsible housing policies.
