Abstract
Climate change is expected to exacerbate the already serious challenges to human health, food security and economic development, especially in African continent where people are already struggling to meet the challenges posed by existing climate variability. Climate, more especially temperature has a strong and direct influence on development, reproduction and survival of tropic insects such as ‘mosquitoes’. Insect population growth potentials are mainly temperature driven, so a rise in temperature may either increase or decrease insect development, likewise rainfall. This paper highlights the rate of mosquitoes bite as evidence by malaria incidence in the study area, which is attributed to the influence of local climate invariability. The study employed the use of 20 years (1991-2010) climate (rainfall and temperature) data of Orlu from Nigerian Meteorological Agency with 20 years data also on malaria cases in Orlu collected from the health centers in the area. Results of the study show variability in the climate of the area, and further reveal that more than 50% of malaria incidence is caused by temperature increase alone in the area. However, suggestions were made on how to avoid mosquitoes bite and other impacts of climate variability.
