This report fills a gap-in-knowledge and offers a comprehensive, accessible framework to demonstrate how gender, climate and security are inextricably linked. It also highlights concrete ways to take advantage of these linkages to prevent conflict and foster lasting peace.Women and girls are facing disproportionate economic burdens due to different types of marginalization; gendered expectations can lead men and women to resort to violence when traditional livelihoods fail; and important socio-economic shifts can result from changes to patterns of migration. Research supporting the report shows that in Chad, gender-based violence and structural inequality limit the capacity of communities to adapt to climate shocks. In Sudan, the growing scarcity of fertile land caused by extended droughts and rainfall fluctuation is marked by increases in local conflict between farmers and nomadic groups. Many people – mostly men – have migrated away from local villages in search of alternative livelihoods in large agricultural schemes or in nearby mines, leaving women with greater economic burdens. Other examples highlight climate-related security risks for women in urban areas, especially within informal settlements. Research from Pakistan and Sierra Leone suggest that water shortages, heat waves, and extreme weather events can create new risks of gender-based violence and deepen pervasive inequalities.
