The Leeds Africa Climate Hackathon aimed to generate user-relevant narratives of possible future climate in East and West Africa relevant to hydroelectric power generation and agriculture respectively. Here we discuss how the virtual hackathon was organised, present the results, and examine the lessons learned from running such a hackathon. We found East African hydroelectric power generation will need to store more water during heavier rain events and cope with longer drought periods in future. Agriculture in Ghana will face a much greater possibility of severe droughts by mid-century especially if 1.5 degC global warming targets are not met.
