The purpose of this project is to map regions impacted by high heat against vulnerable populations affected by high heat across WA. We are developing targeted strategies, actions and resources to enable communities, including government agencies, and those most vulnerable to better prepare for high heat-related consequences to their health and well-being. We are working closely with communities across our three pilot sites to develop heat interventions, as well as working with the Department of Communities and Department of Health to develop an interactive heat vulnerability map.
