Wildfire, floods don’t need to turn into disasters: UN risk report

“We can let nature work when we give spaces back to it. We can promote sustainable consumption by being mindful of where our food comes from and where we buy it.

Strong winds and high temperatures have caused wildfires to spread across Athens in Greece. Other common root causes found in the report include inequality of development and livelihood opportunities, human-induced greenhouse gas emissions, and legacies of colonialism. It is root causes like these that can be found in disasters around the globe. 

Connecting the dots

An even deeper dive shows that the drivers of disasters are formed by shared root causes which are more systemic in nature, such as through economic and political systems.
“We can work together to prepare our communities in the event of a disaster,” says O’Connor.  “The point is that we, as individuals, are part of a larger collective action, which goes a long way in creating meaningful positive change. We are all part of the solution”.
However, the solutions are also interconnected, which means that one type of solution can be applied in several contexts to reduce the impact of disasters in different parts of the world. Additionally, there are multiple solutions to address one disaster and they are most powerful when applied in combination with each other.
In three of the events analyzed in the report – the British Columbia Heatwave, the Tonga volcano and tsunami, and Lagos floods, in Nigeria – early warning systems could have reduced fatalities the report finds. 
To connect the dots, the research team of the Interconnected Disaster Risks report looked “below the surface” of each disaster and identified the drivers that allowed them to occur in the first place.

Deforestation can be traced back to placing economic interests over those of the environment and to unsustainable consumption patterns.The latest Interconnected Disaster Risks report, from the UN University Institute for Environment and Human Security (UNU-EHS), finds that many of these disasters shared root causes. At the same time, the study’s authors found that the solutions to preventing or managing them are also closely linked.

‘Let nature work’

For instance, deforestation leads to soil erosion, which in turn makes land highly susceptible to hazards such as landslides, drought, and sandstorms. 
From record-breaking heatwaves in British Columbia, to wildfires in the Mediterranean, floods in Nigeria, and droughts in Taiwan; the period between 2021 and 2022 saw record-breaking catastrophic disasters in all corners of the world.
“We have the right kind of solutions to better prevent and manage hazards, but we need to urgently invest in scaling them up and developing a better understanding of how they can work in combination with each other.” 
Not all solutions will be convenient for everyone. The redistribution of resources among generations, countries, and groups of people with different vulnerabilities, or requesting the inclusion of stakeholders who are rarely heard, will mean that some will need to share their resources more broadly than they currently do.
“Disasters occurring in completely different parts of the world at first appear disconnected from each other. But when you start analyzing them in more detail it quickly becomes clear that they are caused by the same things, for example greenhouse gas emissions or unsustainable consumption,” said Dr. Zita Sebesvari, lead author and deputy director of UNU-EHS.
The “let nature work” solution, for example, draws on the strength of nature to prevent risks and avoid disasters.

The connections do not stop at root causes and drivers either, but also with who and what is at most risk; vulnerable groups, in both human settlements and natural ecosystems, continue to be the hardest hit by disasters.  Strong winds and high temperatures have caused wildfires to spread across Athens in Greece.

‘We are all part of the solution’

Maria Antonia, from Baja California, Mexico, wakes up every day before dawn to catch milkfish, corvina and sierrita. Prescribed burning in forests can reduce the risk of mega-fires in the Mediterranean; restoring urban rivers and streams can reduce the impacts of floods like the one that hit New York in the wake of Hurricane Ida; and investing in boosting early warning systems can improve prediction and communication of risks ahead of time.
The solutions are not limited to governments, policymakers, or the private sector. They can also be carried out at the individual level, the researchers urge.
 “If we don’t want the disasters which we are currently experiencing to become the new normal, we need to recognize that they are interconnected, as are their solutions,” says lead author Dr. Jack O’Connor.
