Abstract
Ensuring good quality of health and longevity became a topical for policymakers and academicians. Various determinants, including socio-economic factors, have been discussed in the literature. Nevertheless, the empirical studies on this issue are scanty in least-developed countries like Somalia where the health indicators are poor. In this regard, this undertaking examines the impacts of renewable energy, urbanization, environmental pollution, and economic growth on life expectancy in Somalia for the period straddling 1990–2016. The study uses a novelty machine learning method — Kernel regularized least square (KRLS) method. The empirical results indicated that renewable energy, economic growth, and urbanization are statistically significant; whereas, environmental pollution is statistically insignificant. Renewable energy, economic growth, and urbanization exert positive effects on life expectancy in Somalia and have increasing marginal effects. Besides, bidirectional causality between renewable energy and life expectancy, life expectancy and economic growth, and environmental pollution and life expectancy are established. Moreover, unidirectional causality from urbanization to life expectancy is also observed. The study suggests that a budgetary revision be made to sort out health-related concerns resulting from a lack of healthcare services and poor sanitation for improving the longevity of the people. Additionally, investments in clean energy are necessary as will improve health outcomes without compromising economic growth and life expectancy.
