BACKGROUND:
The impact of climate change-related disasters, such as storms and floods, is influenced by the limited capacity of health systems to meet the increased demand for care during emergencies. In this context, the provision of maternal healthcare becomes significantly compromised, increasing the risk of pregnancy complications and unsafe childbirth conditions.

OBJECTIVES:
To identify and map the existing evidence on how climate change affects access to maternal health services within public health systems.

METHODS:
This scoping review is currently in progress and follows the PRISMA-ScR methodological framework. The process includes systematic searches of scientific databases and relevant grey literature. Studies are being selected based on predefined inclusion and exclusion criteria, focusing on access to maternal health services in the context of climate change-related disasters, specifically within public health systems.

RESULTS:
Initial findings reveal disruptions in prenatal, postpartum, and breastfeeding care during extreme weather events. Limited community involvement in decision-making processes may undermine health system resilience. Policy analyses also point to shortcomings in interagency coordination, information dissemination, and timely resource allocation during emergencies.

CONCLUSIONS:
The interaction between environmental disasters and access to maternal health services is complex and multifaceted. Preliminary evidence highlights the need to strengthen public health system preparedness, implement gender-sensitive interventions, and promote more inclusive community participation.

KEY MESSAGE:
Climate-related disasters limit access to maternal healthcare, underscoring the need for resilient and gender-sensitive public health systems. Poster session 1 (Group A)
