Reclaiming the Tongue of Leadership: Indigenous Language Systems as Catalysts for Societal Transformation in Post-2030 Africa

Abstract

Africa’s development trajectory into and beyond 2030 hinges on an underexplored resource: its indigenous language systems. While global sustainability frameworks such as the United Nations Sustainable Development Goals (SDGs) and the African Union’s Agenda 2063 champion inclusive governance and cultural heritage, their implementation strategies consistently overlook the communicative power embedded in Africa’s over 2,000 indigenous languages. The primary argument is that indigenous language systems are not merely heritage artefacts but dynamic tools for leadership communication. Their deliberate integration into governance, institutional policy, and community mobilisation can catalyse transformative societal change across the continent. Using a multi-sited applied linguistics framework, data were collected across multilingual Kenyan communities, including data from 364 participants in an investigation of Dholuo-mediated health communication in Homa Bay County and data on indigenous language use in economic transactions in Kisii and Migori counties. The findings showed an association between mother-tongue communication and higher levels of civic engagement, greater policy compliance, and stronger collective agency. Dholuo oral leadership registers, corporate naming practices in indigenous languages, and multilingual institutional communication policies were also examined to determine how they reinforced or eroded community authority structures. Theoretically anchored in Ngũgĩ wa Thiong’o’s decolonisation of the mind, Hymes’ ethnography of communication, and African Ubuntu philosophy, the Sustainable Indigenous Leadership Communication (SILC) Model is proposed as a framework that positions mother-tongue-led discourse as foundational to post-2030 African governance. The model integrates language revitalisation with digital innovation, including natural language processing (NLP) infrastructure for low-resource African languages, to support inclusive, artificial intelligence (AI)-driven leadership communication. Reimagining Africa’s sustainable future requires centring indigenous voices, moving beyond the translation of external frameworks into local languages to the reclamation of indigenous epistemic systems as the medium and message of leadership. Policy recommendations target universities, governments, and regional bodies committed to language-inclusive development agendas.
