Air–Noise Pollution Linkages: Testing Innovative Community-Based Adaptation and Mitigation Strategies in Kenya
This case study was conducted in healthcare facilities in Kilifi and Nairobi to explore how environmental monitoring can address the mental health needs of vulnerable perinatal adolescents. Outdoor air quality sensors were installed at Kangemi and Kariobangi North health centers in Nairobi, and Mtwapa and Vipingo health centers in Kilifi, as well as in two households of perinatal adolescents. Community health workers collected air quality, noise exposure, and experiential data on stress and mood. Findings revealed site‑specific variations in PM2.5 concentrations, with Kariobangi recording the highest mean (29.45 µg/m³), far exceeding WHO’s 2021 guideline of 5 µg/m³. Noise monitoring showed consistently elevated exposure, with Kangemi averaging 52.2 dB, surpassing WHO’s recommended hospital threshold (less than 35-40 dB). Household monitoring highlighted operational challenges, including sensor deployment constraints and intra‑day variability. The study demonstrates that air and noise monitoring can strengthen health systems and improve patient care, but emphasizes the need for both mitigation (reducing pollution sources) and adaptation (coping strategies) to protect vulnerable populations.
