A scoping review of the health co-benefits of climate mitigation strategies in South America.

The accelerated production of greenhouse gases (GHG) due to human activity has led to unprecedented global warming, making climate mitigation strategies crucial for minimizing its impacts. South America, a region highly vulnerable to climate change, stands to benefit from implementing such strategies to reduce future risks and generate health co-benefits. This scoping review, aimed to assess the existing evidence on the health benefits of climate mitigation strategies in South American countries. PubMed, Web of Science, and LILACS databases were searched until June 15, 2023. Nine studies published between 2001 and 2021 were analyzed, focusing on Brazil, Chile, and Bolivia. All the studies identified in this review used scenario modeling. They evaluated various GHG emission mitigation strategies, including land management, reducing livestock production, biofuel production, increased active transportation, renewable energy, and waste reduction. Only one study looked at GHG capture and sequestration through afforestation. Given the limited information available, there is a pressing need for more research on the region's potential health, environmental, and economic co-benefits. This review serves as a starting point and suggests that climate mitigation can offer a range of positive co-benefits, such as improved air quality and increased resilience to climate impacts, thereby advancing public health initiatives.
