Public health approaches to ‘Leave No One Behind’ in heatwave resilience: insights from the UK

Heatwaves pose significant threats to vulnerable populations, making resilience efforts crucial. This study aims to explore stakeholders' perspectives on heatwave resilience from a public health perspective, with a specific focus on operationalising the commitment to 'Leave No One Behind' (LNOB) as outlined in the United Nations 2030 Agenda for Sustainable Development. In-depth qualitative interviews were conducted with key stakeholders from national and local government, industry and business, academia, and civil society organizations. Interviews examined stakeholders' understanding of the progress and challenges associated with fulfilling the commitment of LNOB in the context of heat resilience from a public health perspective, in England, UK. Content analysis of interview transcripts was undertaken. Stakeholders emphasize the importance of equity, inclusivity, and public health priorities in heatwave resilience efforts while specifically addressing the commitment to LNOB. Disparities in vulnerability due to socioeconomic factors, challenges in identifying and supporting vulnerable populations, progress made in addressing heatwave resilience, and the role of government and society in improving resilience efforts were emphasized. Stakeholders highlighted the need for targeted interventions, strengthened community support networks, and policy changes to address systemic inequalities and promote inclusivity in resilience strategies. Stakeholders' perspectives underscore the importance of aligning heatwave resilience efforts with global goals, particularly in promoting public health equity and inclusivity. By addressing the challenges identified and implementing the recommendations for improvement, policymakers and practitioners should work towards more equitable and inclusive resilience strategies to safeguard public health during heatwaves.
