Is Your City on the Climate Disaster Risk Map?

Natural disasters related to climate are no longer abnormal occurrences. From record heatwaves spreading throughout Europe to flooding throughout Asia, cities are becoming more vulnerable with the climate agenda in action. With these disasters becoming more frequent and violent, a very special tool is being employed by experts to assess the risk levels in an area.

One useful mechanism is a risk map for climate disasters. The map uses scientific information about rising temperatures, increases in sea level, storms that behave differently, droughts, and other perils to highlight different kinds of cities that might be the most dangerous to life in the years ahead. Think about how much better positioned governments, planners, and even people would be with a more definitive outlook on the vulnerability of their home cities.

At present, it may never be more critical to keep these cities tracked on the risk map. Rapid urban expansions are happening, with millions of people living in areas highly exposed to floods, extreme heat, or storms. Knowing whether your city is on this map is the first step to being prepared along the lines of what lies in the days ahead.

What is a Climate Disaster Risk Map?

A climate disaster risk map is similar to a hazard map that depicts areas of the world most likely to be affected by extreme weather events. The map combines our knowledge about global temperature rises, higher storms, floods, droughts, and sea level rise from aerial photographs and maps produced from seismic data.

Scientists, government, and international institutions analyze the varying levels of risk and create the maps in order to provide residents with transparent visualizations of areas of vulnerability. Risk maps are not just about forecasting disaster but are also intended to help cities or communities be better prepared.

For instance, if a city is plotted in a high risk zone, decision makers may work to improve infrastructure, drainage, and emergency planning along with citizens using this knowledge to remain aware of their situation and make better decisions.

Key Factors That Put Cities in Danger

Not all cities are equally at risk. Some may always be subject to threats given the geography or the risks that local building codes allow. Here are a few key factors that define a city's risk:

• Geography - Coastal cities or cities on a shallow river delta or earthquake fault line are highly susceptible to floods and storms or earthquakes respectively. Low-lying coastal cities are experiencing sea level rise challenges, whereas inland cities with little to no rainfall are facing drought challenges.
• Population density - The higher the population density, the more difficult evacuation for people in a disaster and getting help before it's too late. Cities at risk in urban areas can have higher loss of life and property.
• Weaknesses in Infrastructure - Cities with bad drainage, weak structures, and transportation limitations are not ready for disaster. Building infrastructure, building structures for recovery means recovery happens quicker.
• Social economic factors - Poverty, lack of health care and weak governance make cities vulnerable. Cities with fewer resources often struggle the most post disaster.

Examples of Cities at High Risk Global Climate Disasters

Certain cities already firmly occupy the top ranks of global climate disaster risk maps because of their geography and or the rapidity of their development. These are some examples of those cities:

• Mumbai, India – Weighing in as a megacity on the coast with millions of people - Mumbai is particularly vulnerable to rising sea levels, flooding, and extreme storms.
• Jakarta, Indonesia – Potentially the fastest sinking city in the world, sinking and flooding occur regularly in Jakarta.
• Miami, USA – Sea level rising and strong hurricanes will continue to make Miami one of the most climate endangered areas in North America.
• Dhaka, Bangladesh – Dhaka has extreme population density as well as periodic flooding, it will be especially impacted by the effects of climate change.
• Los Angeles, USA – Los Angeles is going to have chronic risk from things like wildfires, driven by longer heatwaves.
• Athens, Greece – Athens will increasingly suffer longer summers and heat to an insupportable degree in Europe, where already many weather stations report high ranges in temperature.

How to Know if Your City is on the Risk Map

So you may be asking, how do I know if my city is at risk? Here are several ways to find out:

• World reports and studies – Global organizations (UN, World Bank, IPCC) were ranking all cities in relation to disaster risk in their global reports.
• Government websites - Several countries and other political entities have now launched websites about climate and disasters, to inform the citizens about local risk maps, weather alerts and guidance.
• News and research stories – National and international media outlets frequently report which cities are most at risk.
• Everyday signals - You may not even need to refer to the reports. If you have extreme flooding, increasingly strong storms, hot summers, drought months with water shortages, your hometown city is already on the risk map.

Conclusion

And it follows, with the impact of climate change, disasters will occur more rapidly, more devastatingly and less predictably. Any city would never have true safety again. Some cities are more vulnerable due to geographical features, existing infrastructure, or population increase in urban areas, however, all cities need to prepare for what is to come.

Knowing whether or not your city is on the climate disaster risk map is the first step. The next step is to take action; pushing for better planning from our leaders, supporting environmentally sustainable policies, and being prepared personally and communally. Together these steps will minimize damage and prepare our cities for a changing world.
