Public Health Expert and planetary researcher Oluwole Ajayi has called for immediate action in response to the growing threat of disease proliferation exacerbated by climate change.

With over 8 years of professional experience in the field, Ajayi, who is currently pursuing a Master of Arts degree in International Development from Clark University, Worcester, USA, and holds a Bachelor of Science degree in Applied Biochemistry and Postgraduate Diploma in Clinical Biochemistry from the Federal University of Technology, Akure, in an interview with newsmen highlighted the critical intersection between climate change and public health.

“The adverse effects of climate change have not only been seen in environmental impact such as flooding, poor crop yield and insect resistance, but also have implications for vector-borne disease propagation. What this means is that diseases will mutate and become harder to treat as a result of the mutation in the vectors that carry these diseases.

“A close example is the increasing rise of antimicrobial resistance because the microbes that cause the diseases that these drugs are supposed to treat have been mutated in the vectors that bear them.” He explained.

Ajayi who has had notable success in delivering interventions to rural communities in Nigeria further notes that “The goal is not only to acknowledge that these things are our current realities, but to collaborate to drive urgent targeted interventions and climate action to mitigate these impacts one community at a time”.

In his research on “Application of satellite imagery for vector-borne disease monitoring in sub-Saharan Africa: An overview”, Ajayi discusses the application of satellite imagery (also known as remote sensing) data for vector-borne disease monitoring in sub-Saharan Africa, highlighting the diseases that are prevalent in the region and the effectiveness of remote sensing data to monitor the spread and prevalence of these disease conditions including filariasis, dengue fever, malaria, leishmaniasis and African trypanosomiasis commonly known as sleeping sickness.

“This research also explored the current applications of remote sensing and GIS (geospatial information systems) to enhance understanding of the role of environmental conditions in influencing vectors of infectious disease and the propagation of disease transmission as well as vector-borne disease surveillance, prevention and control.

“The results of the study revealed that remote sensing, GIS and statistics in disease mapping and epidemiology have significantly advanced the capabilities to monitor and predict the spread of vector-borne diseases in sub-Saharan Africa especially in “developing near real-time monitoring spatial models that can predict temporal and spatial patterns of vector-borne diseases and transmission risk accurately.” and “give epidemiologists a fresh viewpoint when it comes to identifying the environmental causes of the diseases in question.”

Ajayi’s research spotlight the crucial role of satellite imagery and geospatial technologies in providing timely and accurate data for effective disease surveillance and control. This data-driven approach not only enhances our understanding of how climate-driven environmental factors influence disease propagation but also bolster proactive measures to mitigate the impact of these diseases on vulnerable populations.

As climate change continues to reshape ecosystems and disease landscapes, Oluwole Ajayi remains committed in his call for concerted action towards improving health outcomes, the imperative of forward-looking policies and community engagement to safeguard public health in an increasingly volatile climate as well as the application of technology to address public health challenges in resource-limited settings.
