ABSTRACT
Global warming and its impact on malaria incidence is a cause for concern. Malaria, a vector-borne disease, is sensitive to weather and climate conditions. Increased human activities in wetlands make the populations living there particularly vulnerable to climate-related diseases, including malaria.
This study examines malaria incidence and the impact of climate change on the populations living in Bonaberi and Tombel. The observed parasite ratio (PR) is obtained from the national malaria program, while precipitation data is sourced from the Famine Early Warning Systems Network. Temperature data is derived from the ECMWF ERA-Interim reanalysis data. Simulations are performed using the VECTRI model to study the observed and simulated PR in Tombel and Bonaberi and to project the PR for these areas using CORDEX projection data under two representative concentration pathway (RCP) scenarios(RCP2.6 and RCP8.5).
Results show that both Tombel and Bonaberi experienced peaks in PR, with Tombel reaching a PR of 0.8 and Bonaberi showing a slight increase to a PR of 0.9. Future projections indicate a fluctuating increase in PR for Bonaberi, reaching 0.95, and Tombel peaking at 0.9.
