Climate Change is among the greatest threats to health in the 21st century, requiring urgent scale-up of adaptation interventions. We aim to summarize adaptation interventions that were funded by the Belmont Forum and the European Union, the largest global funders of climate change and health research. A systematic search was conducted (updated February 2023) to identify articles on adaptation interventions for health within this funding network. Data extracted included study characteristics, types of interventions, and study outcomes. Results were synthesised narratively within the PRISMA-ScR guidelines. 197 articles were screened, with 37 reporting on adaptation interventions. The majority of interventions focused on the general population (n=17), with few studies examining high-risk populations such as pregnant women and children (n=4) or migrants (n=0). Targeted interventions were mostly aimed at behaviour change (n=8) and health system strengthening (n=6), while interventions with mitigation co-benefits such as nature-based solutions (n=1) or the built environment (n=0) were limited. The most studied climate change hazard was extreme heat (n=26). Several studies reported promising findings, principally on interventions to counter heat impacts in workers and pregnant women, and improving risk awareness in communities. These findings provide a platform on which to expand research and public health interventions towards safeguarding public health from the effects of climate change.
