African communities are among those most profoundly impacted by the climate crisis, even though they have contributed little to climate change (CDP, 2020). This crisis is especially felt by African youth, who are already disadvantaged and marginalized by political and economic conditions. Like elsewhere around the world, the existential threat of the climate crisis has led to a surge in youth-led climate activism in Africa. Nevertheless, less attention is paid to voices originating from the Global South, especially in Africa.This dissertation explores the plight of young African environmental activists in sub-Saharan nations by considering what strategies and tactics they have used to be seen and heard. To do so, it explores the challenges of communicating climate change, by asking how these young activists are attempting to use communication, information, and media tools to confront the region’s unfolding ecological crisis, educate the public, and challenge misconceptions about climate change while elaborating a social movement network across multiple African nations. To pursue this goal, it draws from African media studies (Madrid-Morales et al., 2021; Mano & Milton, 2021; Wasserman, 2018), media activism (Lim, 2018; Rodríguez, 2011), and ecological activism (T. Bosch, 2012; Fonseca & Castro, 2022; Gonzalez et al., 2021; O’Brien et al., 2018; Wolfe, 2008), to conduct a multi-sited ethnography of activists from eight African countries. The study is organized as case studies developed through a combination of in-depth interviews with the activists, analysis of the texts they have produced through digital platforms, and their relationships with their own communities as well as, more broadly, youth-centered climate activist networks emerging in the Global South and elsewhere. The findings indicate that African climate activists evolve through stages leading to their engagement. To speak for the environment and engage their audiences, they educate themselves and learn to creatively employ traditional and new media. In the process, they must also navigate a social and cultural landscape of racism, ageism, tokenism, and political repression through networking, self-care, and ingenuity. Their stories expand current understanding of eco-activism strategies and tactics, such as boycotts, public appearances, and disruptive social media virality, underscoring their place within ecological jeremiads that offer, in turn, new insights into the growing field of African Media Studies. / Media & Communication
