Abstract: This policy brief explores the gendered dimensions of the climate-conflict nexus in arid and semi-arid cross-border regions of the Horn of Africa, specifically Mandera Triangle (Kenya?Ethiopia?Somalia) and the southwest Ethiopia?northwest Kenya borderlands. Through 47 key informant interviews and 20 focus group discussions, the study identifies four pathways through which climate change exacerbates resource-based conflict: (1) scarcity-driven competition over water and pasture, (2) shifting transhumance routes increasing intergroup tensions, (3) climate-induced migration enabling land grabbing, and (4) livelihood disruption prompting cross-border incursions. The research highlights the active?though often overlooked?roles of women in conflict and natural resource dynamics, including incitement, provisioning, and adaptation. It underscores how climate-induced conflict is altering gender norms, creating both burdens and opportunities for women in leadership and decision-making. The brief calls for gender-transformative, cross-sectoral programming and deeper integration of gender into climate-conflict frameworks.
