The climate crisis and health in humanitarian settings

MSF Scientific Days in Latin America 2024 focused on two thematic areas:

Climate Emergency in the Americas: What Are We Seeing as a Medical Humanitarian Organization and How Are We Responding?

• MSF has long responded to health crises aggravated by the climate emergency —such as disease outbreaks, food insecurity, and displacement—and these events are intensifying in severity and frequency. This session presented examples of how MSF is adapting to address climate-related emergencies in the region, and explored strategies for future humanitarian action.

Mental Health and Psychosocial Support Interventions in Violence, Migration, and Indigenous Health Projects

• This session explored the complexities of providing mental health and psychosocial support (MHPSS) in some of the region’s most challenging settings. It focused on interventions in areas affected by violence, the mental health impact on migrants, and the unique needs of indigenous populations. The discussion highlighted innovative strategies, culturally sensitive approaches, and the importance of integrating MHPSS into healthcare projects in these complex settings.

Globally, the number of older people is rapidly increasing, with those aged 60+ expected to more than double by 2050—yet in humanitarian crises, they remain one of the most neglected groups. Older adults often face higher risks due to chronic illnesses, mobility issues, and limited access to appropriate care, especially in low-resource or emergency settings. Despite these needs, humanitarian responses rarely prioritize them, and data on their health and mortality are often lacking.

This collection reflects MSF’s ongoing examination of its own data and practices to identify pathways toward more age-inclusive services in humanitarian crises. It includes analysis of data from MSF-supported mental health services, inpatient departments, and sexual violence services, and further offers several calls to action and reflections on why older people remain overlooked in humanitarian crises. However, MSF also acknowledges major challenges remain, including inadequate age-inclusive services, data gaps, and the need for more geriatric expertise.
