This report examines how climate change is exacerbating security risks across the OSCE region through gendered and intersectional pathways. Drawing on policy mapping and stakeholder interviews, it shows that climate-related security risks are highly context-specific but share common structural drivers—including inequality, weak institutions and political marginalization. Gender, age, class, disability and rural–urban divides shape differentiated vulnerabilities, yet remain insufficiently addressed in climate and security policy frameworks. The report highlights the critical role of women- and youth-led initiatives in driving local adaptation and resilience, while underscoring the need for stronger institutional support. It identifies entry points for more gender-responsive climate-security policies—including inclusive participation, strengthened evidence bases, investment in community resilience and livelihoods, protection of environmental rights defenders, and enhanced cross-border cooperation across the OSCE region.
