Abstract
This study aims to analyse the impact of solar and ultraviolet radiations on human health and agricultural productivity in Lagos, Ibadan, and New Richmond. Solar radiation is essential for warmth and photosynthetic activities by plants. However, excessive to both radiations can lead to harmful consequences on both animals and plants. Using wavelet analysis, the study examines patterns and trends in the hourly data of solar radiation as well as ultraviolet radiation from 1st of January, 2000 to 31st of December, 2020. The findings reveal significant correlations between levels of solar radiation and ultraviolet radiation and their health outcomes, such as skin cancer rates and vitamin D synthesis, as well as agricultural impacts like crop productivity and plant health in the study locations. These results highlight the need for tailored health interventions and agricultural practices to mitigate the adverse effects of radiation in the selected locations, such as, avoiding long stay in the sun in Lagos and Ibadan, and introduction of UV radiation enhanced plants in New Richmond.
