Analyzing Australia’s 2019 Wildfires in the Northern Territory and Surrounding Syndey Region
Introduction
Devastating wildfires have a long history in Australia, and as the country’s environment worsens with them, the danger of flames is only going to grow worse. Australian wildfires continue to devastate the nation’s natural environment, threaten its indigenous species, and endanger the health of its citizens. Our project explores the connection between how the 2019 Australian wildfires affected different regions of the country.
We delve into whether the Aboriginal and Torres Strait groups were affected in an inequitable manner by these fires compared to individuals in urban areas. Using the data and imagery drawn from satellites by LANCE FIRMS operated by NASA’s Earth Science Data and Information System (ESDIS), we focus specifically on the Northern Territory (NT) and greater Sydney area. We will analyze health impacts bared by environmental factors. The original source that motivated this data set is “Australia fires: Misleading maps and pictures go viral” by BBC News reporter Georgina Rannard which displays maps and pictures of Australia’s unprecedented bushfires that have spread rapidly and widely on social media.
Through our research we argue that Indigenous versus non-Indigenous demographics have a noticeable impact on overall health impacts as one group is more exposed than the other to harmful emissions from these wildfires. For example, according to the Australian Bureau of Statistics, lower respiratory disease is a leading cause of death in Aboriginal and Torres Strait Islander people within the Northern territory. The number of total deaths are nearly doubled versus in the urban population within New South Wales. We incorporated data from the Australian Bureau of Statistics to examine the health impacts due to the fires. By narrowing our focus on the representation of percentage share of total deaths that chronic lower respiratory diseases had in 2017, 2019, and 2021, we are able to clearly identify that there is a clear unequal divide between populations.. These statistics are relevant for our argument to show that the Aboriginal and Torres Strait groups were affected in an inequitable manner by these fires compared to individuals in urban areas.

1st Research Question
How did the 2019 Australian wildfires affect different regions (Northern territory vs greater Sydney area) and people of the country from a lens of the health impacts bared by environmental factors?
2nd Research Question
Were Aboriginal and Torres Strait communities affected in an inequitable manner by these fires compared to individuals in urban areas?
Literature Review
Our review of the literature revealed that academics concur that wildfires have a major impact on public health. Known as the “Black Summer,” the Australian wildfires of 2019 caused severe respiratory problems, mental health issues, and worsened pre-existing medical disorders, according to the Integrated Environmental Assessment and Management series (Dickman 2021). This was especially detrimental, leading to a rise in hospital admissions for cardiovascular and respiratory ailments. Studies done by the International Journal of Environmental Research and Public Health on air quality and health show that the kind and degree of health effects differed by location (Nguyen 2021). Smoke pollution caused acute respiratory problems and significant air pollution in the Greater Sydney Area. On the other hand, although the Northern Territory was similarly impacted by smoking, it had to deal with other issues like damaged infrastructure and restricted access to healthcare. A study done by the Australian Institute of Health and Wealthfare found how a significant portion of hospital budgets for Aboriginal people is allocated towards treating environmental determinants because of gastrointestinal and respiratory diseases and illnesses (Australian Institute of Health and Welfare 2021). Not only does this signify a current problem to address as the fires in recent years have been particularly damaging but it also undermines recent legislation and aid that has not been thorough enough to help these impacted groups.
Multiple studies have consistently shown that exposure to wildfire smoke is linked to respiratory morbidity. In addition to its fatal effects, bushfire smoke has also been related to increased risks of hospitalization and emergency department visits due to respiratory diseases such as asthma, chronic obstructive pulmonary disease, and respiratory infections. Increasing evidence also suggests bushfire smoke might increase cardiovascular morbidity, psychological disorders, adverse birth outcomes, and eye irritation (Yu 2020). Because Indigenous people in the bushfire-affected area have younger population profiles, more than one-tenth of children in the bushfire-affected area are Indigenous, raising the diverse effects of bushfires on infants and children in particular. While most of the literature reaches the same conclusion that the Aboriginal and Torres Strait people were more affected in Northern Territory than those in New South Wales, there are some discrepancies. For example, studies on the Northern Territory are less extensive than those on the Greater Sydney Area, which has drawn a lot of attention because of its economic significance and high population density. The impact of the flames on more rural and isolated places may have been underestimated as a result of this disparity (Nguyen 2021). Academics concur that improved emergency response and healthcare infrastructure are essential, particularly in rural and isolated locations. The fires brought to light weaknesses in the current systems that must be fixed in order to better handle emergencies in the future.
