This study compares and contrasts machine learning approaches to benchmark best practices for the Rwandan context and to evaluate the added value of advanced statistical methods for air quality monitoring in data-scarce settings. We forecast fine particulate matter (PM2.5) concentrations across five provinces in Rwanda, using multi-year meteorological and air quality data to identify context-specific patterns. This work establishes a methodological foundation for context-optimized early warning systems and informs policy interventions to improve air quality management in Rwanda. By rigorously testing machine learning capabilities against regional constraints, we demonstrate how machine learning can reduce population exposure to pollution, quantify attribution gaps in under-monitored regions, and improve sustainable environmental governance in resource-limited settings. The results indicate significant seasonal variability, with higher PM2.5 levels during dry seasons than wet seasons. Our evaluation demonstrates that machine learning models can capture complex, non-linear relationships between environmental variables and pollution trends, although performance varies between algorithms. Limitations remain, including the integration of real-time data streams and localized variables such as industrial emissions, road traffic, and agricultural practices. |  |\n| Keywords:\u003Cbr>Air qua","cbCaiqYs7ad6vgKK","https://ap.wps.com/l/cbCaiqYs7ad6vgKK","pdf",12458299,1,18,"English","en",105,"# Introduction\n## Air pollution as a global health risk\n## Policy and mitigation efforts\n# Methods and Modeling\n## Forecasting PM2.5 using multi-year data\n## Benchmarking machine learning approaches\n# Results and Implications\n## Capturing non-linear relationships and seasonal variability\n## Limitations and future needs","[{\"question\":\"What problem does the study address?\",\"answer\":\"The study addresses the challenge of accurately forecasting air quality to support public health and environmental management.\"},{\"question\":\"How is PM2.5 forecasting performed in the study?\",\"answer\":\"It forecasts fine particulate matter (PM2.5) concentrations across five provinces using multi-year meteorological and air-quality data.\"},{\"question\":\"What are the main findings about model performance?\",\"answer\":\"Machine learning models can capture complex, non-linear environmental relationships and reveal significant seasonal variability, though performance differs by algorithm;
