Unmanned aerial vehicles (UAVs), with their ability to provide real-time data, high-resolution imagery and rapid assessment capabilities, are fast becoming indispensable tools for effectively and efficiently managing disasters, says specialty insurance company iTOO Special Risks drone expert Kopano Tholo.
He notes that using drones for disaster management is becoming increasingly common in South Africa where they are used to assess infrastructure damage and areas affected by disasters – such as chemical spills, floods and wildfires – by analysing crucial data for emergency response planning.
Tholo notes that UAVs play an important role in creating two- and three-dimensional maps through aerial reconnaissance – especially in inaccessible areas – making it easy for rescuers to identify potential hazards and plan for relief.
“Drones equipped with high-resolution cameras and sensors rapidly capture detailed images and data, creating accurate maps of areas affected by disasters. This quick assessment helps authorities identify the most impacted zones, plan rescue operations, and allocate resources efficiently,” he says.
Drones are also beneficial for search-and-rescue missions, as they can cover large distances over short periods of time as opposed to traditional, manual search mission processes, which often require the deployment of teams of people searching on foot.
Additionally, drones that are equipped with thermal imaging cameras can detect heat signatures from people trapped under debris or lost in remote locations, even in low-light conditions, which greatly enhances the likelihood of promptly locating and rescuing survivors.
Further, drones can also be deployed to monitor ongoing hazards, providing real-time data on their progression. This information is critical for implementing containment strategies, evacuating at-risk populations and preventing further damage.
“Post-disaster, drones can inspect critical infrastructure such as bridges, roads and power lines to assess damage and prioritise repairs. This accelerates the restoration of essential services and aids in the recovery process,” he adds.
Given their crucial role in disaster management efforts, the drone market is likely to see exponential growth in the future – especially in a country like South Africa where floods and wildfires frequently plague certain areas.
“As South Africa continues to face various natural and human-made disasters, the role of drones in mitigating their impact and saving lives cannot be overstated and, as their use continues to grow, ensuring proper drone insurance becomes essential to mitigate risks and protect operators and the public,” Tholo concludes.
