Attaining sustainable development in Nigeria: the role of solid waste, urbanization and pollution in reducing under-five mortality.

The United Nations, through its subsidiary agency United Nations Children's Fund (UNICEF), has put in such resources to curb infant mortality in pursuit of the Sustainable development goals (SDG). Nevertheless, the issue of under-five mortality is still persistent in so many developing countries, especially in sub-Saharan Africa. Therefore, this study investigated the long-term and short-term impacts of solid waste, urbanization, and pollution on under-five mortality, employing the Autoregressive distributed lag (ARDL) and the dynamic Autoregressive distributed lag (DARDL) models for the empirical investigations and robustness checks, respectively.
