Modèle d'infrastructure de données spatiales des actions vertes et bleues pour l'adaptation de l'habitat social fondée sur les écosystèmes en Argentine

This initiative focuses on the development of a Spatial Data Infrastructure (SDI) model of green-blue actions for Ecosystem-based Adaptation (EbA), aimed at improving the social habitat of vulnerable communities in Argentina by providing inputs to social housing programs, plans and projects. The model will be implemented in three selected focus sites, chosen to represent diverse environmental and social conditions across the country.

Social housing policies in Argentina have historically relied on standardized, one-size-fits-all approaches, often overlooking regional and even local differences in climate, topography, ecosystems, and local practices and behavior. In response, this initiative shifts the focus from “housing” to the broader concept of “habitat”, understood as a socio-ecological system embedded in its local context.

The proposed approach integrates social, environmental, and spatial dimensions through a framework that combines analysis of socio-ecological systems, identification of local challenges and existing adaptive capacities, and assessment of major climate impacts.

This framework is complemented by the development of a technical database of green-blue infrastructure actions to implement EbA initiatives that evaluates their environmental, social, and economic benefits.

Both components are then articulated within a Spatial Data Infrastructure (SDI) model tailored to each focus site, enabling context-specific responses, while maintaining a consistent methodological framework across regions and ecosystems.

The results will be made openly available to communities and decision-makers, supporting participatory validation processes, knowledge transfer, and fostering capacity building. The initiative will be delivered through an open-source, user-friendly map platform designed to be accessible to a wide range of stakeholders, irrespective of their level of technical expertise, contributing to climate change adaptation and mitigation, as well as to the improvement of ecosystem health conditions.

Expected Key Milestones:

Milestone 1: Development of a baseline report that comprises the assessment of key social challenges (particularly climate vulnerability and housing demand), the definition of criteria for the selection of three socio-ecological units (focus sites), identification and characterization of the three focus sites through maps, figures, and descriptions, the analysis of occupation patterns, as well as a policy review of existing social housing programs with a focus on social and environmental features in the sites.

Milestone 2: Development of a Climate Impact Chain through the identification of hazard, exposure, and sensitivity indicators to assess vulnerability and associated risks, the evaluation of technical knowledge and skills, and social and institutional capacities for adaptation, the quantification and interrelation of variables, and the categorization of risk levels across the three focus sites.

Milestone 3: Development of a green-blue infrastructure model for Ecosystem-based Adaptation based on a comprehensive review of national and international literature, including the identification of benefits of each measure/solution pursuant to the climate impact chain, the analysis of economic and financial variables such as investment levels, funding types, and co-benefits, and the integration of these variables into an exhaustive matrix.

Milestone 4: Development of a Spatial Data Infrastructure (SDI) model integrating climate change variables, social challenges, and green-blue infrastructure measures into a structured data matrix to support analysis and decision-making. The SDI will consist of an open-source, user-friendly map platform designed to be accessible to and applicable by a wide range of stakeholders, regardless of their level of technical expertise

Milestone 5: Dissemination of results to key stakeholders through outreach oriented collaborative activities and communications, and elaboration of the final report.
