Hazard Breakdown
Climate Hazard Breakdown for Maningrida
Flood
Maningrida faces a high risk of flooding due to its low-lying coastal location and proximity to rivers. Intense rainfall events can lead to riverine and flash flooding, impacting residential and commercial areas.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfires in Maningrida is moderate, with the surrounding savanna grasslands and woodlands posing a potential fire hazard during the dry season. Changes in temperature and rainfall patterns could exacerbate fire risk.
Key drivers:
- ·Increased temperatures
- ·Prolonged dry periods
Heat
Maningrida experiences high temperatures and humidity, particularly during the wet season. Climate change is expected to increase the frequency and intensity of heatwaves, posing health risks to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As a coastal community, Maningrida is vulnerable to the impacts of sea level rise and coastal erosion. Rising sea levels can inundate low-lying areas, damage infrastructure, and displace communities.
Key drivers:
- ·Sea level rise
- ·Increased storm surge
Wind
Notable wind risk — tropical cyclone winds
Storm
Notable storm risk — cyclones and monsoonal storms
Social
Moderate social stability — remote communities
Energy
Elevated energy costs — year-round cooling

Learn moreAbout Maningrida's Climate Risk Profile
Maningrida, located on the coast of Arnhem Land in the Northern Territory, is highly vulnerable to the impacts of climate change. The community's low-lying coastal location makes it particularly susceptible to flooding from intense rainfall events and rising sea levels. The combination of these factors poses a significant threat to the town's infrastructure, housing, and cultural heritage.
Bushfire risk is also a concern, with the surrounding savanna grasslands and woodlands prone to fires during the dry season. Changes in temperature and rainfall patterns could increase the frequency and intensity of bushfires, threatening lives and property. The region already experiences high temperatures and humidity, and climate change is expected to exacerbate heatwave conditions, posing health risks to vulnerable populations.
Sea level rise is a major threat to Maningrida, with the potential to inundate low-lying areas, erode coastlines, and damage critical infrastructure. The community needs to implement adaptation measures to protect itself from these impacts. These measures may include building seawalls, improving drainage infrastructure, and relocating vulnerable assets.
Addressing climate change in Maningrida requires a collaborative effort involving the local community, government agencies, and other stakeholders. By working together, the community can build resilience to climate change and ensure a sustainable future for generations to come.
