Regional Assessment of Population and Warming of a Tropical Country, Nigeria, from 2006 to 2036
Environmental and Earth Sciences Research Journal
This research assessed population variability and prediction of heat island in a tropical country, Nigeria, from 2006 to 2036. Data for heat island were generated from records of the National Population Commission (NPC) using the population mathematical model. With national population growth rate of 2.67 %, Nigeria recorded average heat island of 6.1 ℃ with variation of 0.1 ℃ per decade indicating that heat island is on the increase. The North Central region had heat island variation of 0.3 ℃
... ariation of 0.3 ℃ per decade; North East had heat island of 0.1 ℃, North West 0.1 ℃, South East 0.1 ℃, South-South 0.2 ℃ and South West 0.2 ℃ respectively. The six regions had heat island of 5.4 ℃ to 5.6 ℃ greater than 0.5-2.5 ℃ recommended standard indicating that human comfort has been compromised in Nigeria. Results show that heat island across the regions differ significantly. Also, population density is not associate variable that causes heat island in the regional landmass of Nigeria. It therefore recommends national planners and development practitioners to implement population control and tree planting strategies. The research has contributed to the interactive roles of population and landmass in heat island effects. Therefore, a control of population growth lowers the effect of heat island in Nigeria.
