This study explores the environmental organizing of the youth in Mathare and its potential to transcend hustle into climate activism. It examines how the intervention of global climate actors and their agendas influence the youth's work. By building an empirical case through the stories and evolution of the youth, using observer participation and participant observation, the research analyzes potential pathways and possibilities for Mathare’s youth groups. Embedded in the discourse of hustle and climate adaptation in informal settlements, this paper argues that the youth's work is transitioning from opportunism to visionary practice. As the youth navigate their precarious employment situations and struggle to find identity and community through hustling, the paper explores their potential to expand their vision and scope, and to collectivize towards climate adaptation, is enabled by opportunities presented by global climate efforts. Finally, the paper invites further research on the potential of youth activism to contribute to effective climate adaptation.
