Despite a robust array of policy frameworks addressing sanitation, waste management and pollution control, Nigeria continues to grapple with systemic environmental health crises. This paper contends that the primary impediment to policy success is not a lack of regulatory structure, but a “communicative rift”, a failure of top-down, technocratic dissemination to resonate with Nigeria’s linguistically and culturally diverse populace. Through a critical analysis of urban centers including Lagos, Port Harcourt and Aba, and other urban centres, the study demonstrates how the marginalization of indigenous knowledge and local languages results in poor policy appraisal and stagnant behavioural change. The research proposes vernacular radio broadcasting as a pivotal strategic asset for environmental governance. By situating radio within the theoretical frameworks of participatory communication and cultural preservation, the paper argues that indigenous-language media can bridge the gap between abstract policy and everyday ecological practice. While highlighting the potential for increased community agency, the study also addresses critical barriers, including the politicization of airwaves, infrastructure limitations and the necessity for professional capacity building. The paper concludes by advocating for a paradigm shift in Nigerian environmental policy, one that transitions from informational “publicity” to a participatory model that centers culture and language. It recommends the formal integration of vernacular broadcasters as strategic policy partners to ensure sustainable, community-led environmental health outcomes.
