Today the most substantial threats facing cities relate to impacts of climate change. Extreme temperature such as heat waves and occurrence Urban Heat Island (UHI) phenomena, present main challenges for urban planning design. Climate deterioration exacerbates already existing weaknesses in social systems, which have been created by changes population increases sprawl. Despite numerous attempts researchers assess risks associated with heat-health nexus areas, no common metrics yet defined yet. The objective this study, therefore, is provide an empirical example a flexible replicable methodology estimate micro-scale UHI within context takes into account all relevant elements regarding nexus. For purpose, city Turin has used case study. methodological approach adopted based on risk assessment guidelines suggested approved recent scientific literature. framework presented here quantitative per each census tract interaction three factors: hazard, exposure, vulnerability. Corresponding georeferenced maps indicator provided increase local knowledge spatial distribution vulnerability drivers. proposed related findings represent initial stage investigation This will include participatory processes policymakers health-stakeholders view guiding agenda change adaptation resilience strategies City Turin.
