Sustainable Diversified Economy (SDE) is significant in realizing sustainable economic growth in Nigeria. Information and Communication Technologies (ICTs) have made landmark innovational trends in empowering diversified economy globally. Despite these global impacts of ICT on diversified economy, numerous investigations have shown that poor sustainability of ICT in Nigeria has hindered economic diversification. SDE which is the pivot for economic growth, has remained relatively low or unnourished due to: corrupt policies and practices, ignorance, illiteracy, and bad economy that plagued sustainable ICT innovations. In this study, the authors explored a narrative review that focused on the theoretical underpinnings of vast works of literature that revealed significant information on impact of sustainable ICT on sustainable diversified economy, analysis, and synthesis of prior research, and its adoption and sustainability in Nigeria. The authors also used some keywords such as “ICT and SDE”, “ICT and diversified economy”, “Trends for ICT”, and so on, to extract peer-reviewed articles within the last five years from electronic databases. The result of this study revealed that strict adherence to policies, laws and guidelines on the adoption and sustainability of ICT coupled with good formulation and communication of same, are the major impact of sustainable ICT that can leverage SDE in Nigeria. Result from this study may increase understanding, minimize corrupt practices and encourage trust in ICT innovations, ICT adoption, acceptance and sustainability that can positively impact SDE and economic growth in Nigerian.
