Background of the Study
Climate change and air pollution are intertwined global challenges that significantly affect human health. In Oyo State, rising temperatures, altered wind patterns, and increased industrial activities contribute to worsening air quality, thereby heightening the prevalence of air pollution-related illnesses such as asthma, bronchitis, and cardiovascular diseases (Adeyemi, 2023). The exacerbation of air pollution by climatic factors is particularly concerning in urban and peri-urban areas of Oyo State, where rapid urbanization and industrial growth have led to increased emissions of pollutants such as particulate matter (PM₂.₅), nitrogen oxides, and sulfur dioxide (Olatunde, 2024).
The interaction between climate change and air quality is complex. Higher temperatures can increase the rate of photochemical reactions in the atmosphere, leading to the formation of ground-level ozone, a known respiratory irritant. Moreover, climatic conditions such as stagnant air masses during heat waves hinder the dispersion of pollutants, causing them to accumulate in densely populated areas. These environmental changes have direct implications for public health, with vulnerable populations—especially children, the elderly, and those with pre-existing conditions—experiencing heightened risks of respiratory and cardiovascular illnesses (Balogun, 2023).
In Oyo State, where economic development and urban sprawl are accelerating, understanding the impact of climate change on air quality and related health outcomes is crucial for effective public health planning. Integrating meteorological data with health surveillance records can provide valuable insights into the temporal and spatial trends of air pollution-related diseases. This study aims to explore the nexus between climate change, air pollution, and public health in Oyo State, offering evidence-based recommendations to mitigate adverse health effects and improve air quality management (Fashola, 2024).
Statement of the Problem
Air pollution in Oyo State has become a critical public health issue exacerbated by the influences of climate change. Increasing ambient temperatures and altered weather patterns have led to poorer air quality, contributing to a rise in respiratory and cardiovascular illnesses. Despite the growing body of evidence linking climate change to adverse air quality, there is limited region-specific research that quantifies these impacts in Oyo State (Soyinka, 2023).
Urban areas in Oyo State are experiencing intensified air pollution due to rapid industrialization and increased vehicular emissions. During periods of high temperature and stagnant weather conditions, pollutant levels can reach dangerous levels, posing significant health risks. Vulnerable groups, including children, the elderly, and individuals with pre-existing respiratory conditions, are particularly affected. The current public health infrastructure is struggling to cope with the rising incidence of air pollution-related illnesses, and there is a lack of targeted interventions that address the unique climatic influences on air quality.
This study seeks to investigate the extent to which climate change exacerbates air pollution and contributes to health complications in Oyo State. By analyzing air quality data alongside health records, the research aims to identify critical periods and regions where interventions are most needed. The findings will support the development of adaptive strategies that can mitigate the health impacts of poor air quality in the context of climate change, ultimately informing policy and public health initiatives.
Objectives of the Study
1. To assess the impact of climate change on air quality and the prevalence of air pollution-related illnesses in Oyo State.
2. To analyze the relationship between climatic factors (e.g., temperature, wind patterns) and pollutant concentrations.
3. To propose adaptive public health interventions to mitigate air pollution-related health risks.
Research Questions
1. How does climate change affect air quality in Oyo State?
2. What is the relationship between climatic variables and the incidence of air pollution-related illnesses?
3. What adaptive interventions can reduce the health risks associated with air pollution?
Research Hypotheses
1. Rising temperatures due to climate change are significantly associated with deteriorating air quality in Oyo State.
2. Poor air quality, influenced by climatic conditions, is positively correlated with an increased prevalence of respiratory and cardiovascular illnesses.
3. Adaptive public health interventions can significantly reduce the incidence of air pollution-related diseases.
Scope and Limitations of the Study
The study focuses on urban and peri-urban areas in Oyo State. Data will be collected from air quality monitoring stations, hospital records, and meteorological databases. Limitations include potential data gaps in historical air quality records and confounding factors from industrial emissions.
