Following recent rains, air quality in Antananarivo has improved, but the respite may be short-lived as weather conditions could trigger new pollution episodes.
Between October 21 and 24, air quality in the capital became unhealthy for the general population. According to the General Directorate of Meteorology, PM2.5 fine particle concentrations reached up to eight times the national standards in areas such as Ampandrianomby, Andraharo, Soanierana, Ambatobe, and Amboditsiry.
Zo Rakotomavo, Director of Hydrometeorological Research and Development, noted that while current levels have dropped to around 15 µg/m³, the outlook remains concerning. Frequent dry spells expected in November and December are likely to cause recurring pollution spikes due to the lack of wind and rain, which prevents the dispersion of pollutants.
The pollution stems from various sources, including vehicle emissions, bush and forest fires, open waste burning, industrial activities like traditional brickmaking, and domestic wood and charcoal cooking. Experts warn that these daily habits make short-term emission reductions difficult.
Health risks associated with this pollution include respiratory and cardiovascular issues, with children, the elderly, and pregnant women being the most vulnerable. The Malagasy Pediatric Society has advised parents to limit outdoor activities and keep windows closed during peak pollution hours.
The Ministry of Environment and Sustainable Development is stepping up prevention efforts, including air quality monitoring, public awareness campaigns, and the promotion of cleaner cooking alternatives like biogas and ecological charcoal. An interministerial working group on air pollution is also set to be revitalized to address the issue across transport and industrial sectors.
