Record fires in southern Australia have blazed over 6 million hectares of mostly eucalyptus forest over the past two months, killing at least 24 people and more than a billion animals.
The fires have forced many people to flee their homes for safety and clouded the air with toxic pollutants. Two datasets on Resource Watch can help us track the toll of the wildfires in near-real time:
Wildfires create smoke plumes made up of several hazardous pollutants including dust and fine particulate matter. Fine particulate matter (PM 2.5) is an easily inhalable air pollutant 2.5 micrometers in diameter, four times smaller than dust or pollen. Levels of PM 2.5, which is linked to heart and lung disease and asthma, reached hazardous levels in many locations across southern Australia over the past two weeks.
Air quality data from Open AQ shows PM 2.5 concentrations from three sensors in Australia’s capital city, Canberra, averaged 438 micrograms per cubic meter in the first six days of January. For reference, 250 micrograms is considered hazardous to human health. The average concentration on New Year’s Day was 792 micrograms per cubic meter. Data from Open AQ updates daily on Resource Watch.
About 90,000 people have been displaced by the wildfires since September, according to data from the Internal Displacement Monitoring Center, a non-profit that tracks where natural disasters or conflicts force people to leave their homes. More than 86,000 people have been displaced over the past 30 days alone (shown in map below), according to the data collected from government authorities, international organizations, news media outlets and other entities. The Internal Displacement Monitoring Center only tracks the displacement of residents, not visitors or tourists.
For comparison, in 2018, 11,000 people were displaced in Australia from natural disasters during the entire year. According to a recent report by the World Bank, more prevalent natural disasters caused by climate change could push tens of millions of people to migrate within their countries by 2050.
