Based on the experiences of the socio-urban integration of Villa 20, this article suggests that upgrading processes are inherently complex and challenge traditional public policy implementation practices. The case presented demonstrates that, when complex urban problems are addressed through citizen participation, they contribute to improving urban governance, providing comprehensive responses, and may ensure the long-term sustainability of the introduced changes. Incorporating a climate resilience lens into the upgrading processes of informal settlements has not been a priority in government-led programmes to date. However, when these processes have at their core a deep participatory and collaborative approach, they offer a window of opportunity not only to transform government practices and policies, but also to influence urban designs, bring technological innovation, support alternative construction practices, and adopt a more sustainable and inclusive urban development pathway.
El trabajo analiza algunas perspectivas conceptuales que atraviesan la definición del espacio público urbano. Se identifican y definen con la finalidad de realizar una propuesta desde la cual estudiar, interpretar, explicar y operar en el espacio público. En esta dirección, se aborda una revisión del concepto de “penumbra”, el cual nos permite plantear una mirada integral y compleja de la problemática del espacio público en el contexto urbano. Se explora el caso de los “habitantes de la calle” y se analizan algunas dinámicas sociales que construyen y son construidas en el espacio público, para finalmente reflexionar acerca del rol de la academia en el diseño y la implementación de políticas públicas urbanas relacionadas con el espacio público.
In recent decades, informal settlement upgrading and housing deficit in Latin America has been addressed through a variety of urban programs, usually structured around physical-spatial and social actions with an emphasis on the provision of basic infrastructure and services, improved accessibility and connectivity and new housing, mostly done by conventional means. In general, they fail to incorporate new frameworks that provide solutions with strong environmental roots, such as Nature-based Solutions (NbS), Blue-Green Infrastructure (BGI) or Ecosystem-based Adaptation (EbA). This article explores the potentiality of NbS/BGI in contributing to solve structural problems in marginal urban areas, the mindshifts and actor coalitions needed to support this and how it may promote equity and justice. This is analyzed in a particular setting: Villa 20, an informal settlement in the City of Buenos Aires that is undergoing a participatory urban upgrading process with a strong participatory platform made up of multiple spaces and devices for consensual decision-making on re-urbanization aspects. In Villa 20, several interrelated projects and programs are focusing on sustainability. In particular, the Transformative Urban Coalitions (TUC) of the International Climate Initiative (IKI) is connecting decarbonization with urban inequalities and urban justice. The article reflects on some of the initial outcomes of the TUC program that builds upon the ongoing participatory upgrading process. To discuss the links between the use of NbS, mindshifts and transformative urban coalitions we look into the social setting, methods and tools that promote mindset shift. We explore initial mindset changes in government teams; community leaders; and participants of an Urban Lab and the building up of a new transformative actor coalition. With this, we aim to better understand the possibilities and potential implications of implementing NbS in marginalized social contexts, contributing both to closing the knowledge gap and re-thinking future policies and programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
