CAGAYAN DE ORO CITY — Northern Mindanao is grappling with severely degraded air quality as smoke from wildfires across Kalimantan, Indonesia drifts into Philippine airspace, creating acutely unhealthy conditions for residents across the region.

The Department of Environment and Natural Resources-Environmental Management Bureau (DENR-EMB-10) regional office has been actively tracking the worsening air conditions, with particulate matter concentrations climbing to concerning levels throughout Northern Mindanao. The transboundary pollution represents a recurring challenge for the region during fire seasons in neighboring Indonesian provinces.

The hazardous air quality poses health risks to vulnerable populations, including children, the elderly, and those with respiratory conditions. Authorities have recommended that residents limit outdoor activities and use protective masks when venturing outside.

Environmental officials continue monitoring real-time air quality data as the region awaits improvements in conditions, which typically depend on shifts in wind patterns and suppression efforts on wildfires across the border.
