This study examined how seed systems in Kenya, Tanzania, and Uganda support farmers' access to climate-adapted seeds and information, while also considering gender roles and institutional dynamics. Both men and women face climate challenges and prefer early-maturing, heat-tolerant, pest-resistant varieties, but women rely more heavily on informal seed sources. Only a small percentage of farmers interact with formal seed experts, highlighting the importance of strengthening both formal and informal networks. The study calls for inclusive, gender-responsive interventions to enhance seed systems and support equitable climate-change adaptation.
