Mother Language as a Catalyst for Sustainable Development: Focus on SDG 4 (Quality Education) in Bangladesh

Abstract

This paper analyzes the potential role of mother languages in promoting sustainable development, with a special focus on SDG 4 (Quality Education) in Bangladesh. In multilingual contexts like Bangladesh, where diverse mother languages are spoken, these languages are essential for achieving social equity, preserving cultural heritage, and fostering inclusive growth. The study highlights the contributions of mother languages to key sustainable development indicators, including education, economic empowerment, and cultural preservation. Drawing on global and local studies, it illustrates the benefits of integrating mother tongues into educational curricula, financial services, and public sectors. Challenges such as linguistic barriers in policy implementation and resource limitations are addressed, alongside policy recommendations tailored for Bangladesh. Evidence underscores the urgency of promoting mother tongues to boost educational outcomes, enhance economic participation, safeguard cultural identities, and support environmental stewardship. An inclusive approach embedding mother languages in national policies is advocated to realize a sustainable, equitable future for all communities.
