Modern drones stand to offer support in combating forest fires and disaster relief operations in and around the southern Cape coast.
In the midst of the worst wildfire to strike the southern Cape coast, South Africa in over 150 years, drones slowly started coming into play as a local firefighting and disaster management tool. Firefighters issued a call for drones equipped with heat mapping capabilities, which would allow them to identify hot spots at the greatest risk of flare-ups – a task virtually impossible for ground crews working in blinding smoke and dense undergrowth. Drones were also harnessed by civilians who filmed the devastation in Knysna and Plettenberg Bay, allowing homeowners around the country and the rest of the world to witness the destruction and confirm whether their own properties were damaged or not.
In years to come, we can expect to see unmanned aerial vehicles (UAVs) or drones taking on an increasingly important role in firefighting and disaster management, says specialist drone firm Airborne Drones South Africa.
JJ Rebello, Foreign Government Relations Manager at Airborne Drones South Africa, says drones will not only improve the effectiveness of firefighting efforts; they will also reduce the risk to human life during firefighting operations and stand to limit damage to assets by enabling firefighters to work proactively, rather than reactively.
“Commercial drones can withstand temperature extremes from below 5 degrees Centigrade, up to 50 degrees Centigrade, and they can be flown to an altitude of 4500 metres, making it possible for firefighters to deploy drones over areas where fires are active. With the use of advanced thermal imaging cameras transmitting data to command centres, they can identify people or animals, even where visibility is limited by darkness, smoke or vegetation, so allowing emergency teams to pinpoint exactly where assistance is needed. Thermal imaging cameras also support proactive firefighting measures, by mapping hotspots where flare-ups could occur.”
Rebello notes that in the security industry, it is estimated that a drone can take the place of 12 foot soldiers. “The same might apply in disaster management,” he says. “Sending in technology reduces risk to human life and allows resources to be deployed only where assistance is needed.”
Drones equipped with Light Detection and Ranging (Lidar) technology support the three-dimensional modelling of forest structures and surface topography, which allows for the development of fire behaviour models, fuel maps and prescribed burn plans. Drones are already being harnessed internationally to monitor and improve planned burns and provide real-time maps of fire progress.
For insurance purposes, drones also offer access to structures that are cut off from road traffic or too high to allow easy access, so supporting claims investigations and processing after disasters. Drone mapping allows insurance firms to rapidly document the scene without intruding on clean-up operations or exposing investigators to potentially hazardous materials; as well as providing data on risk factors associated with the damage.
“Drone technology is proving increasingly important in supporting pre-emptive approaches to fire and natural disaster risk management, as well as for disaster relief support,” says Rebello.

Notre Dame, Scoop Makhathini, GoT, top week in search
From fire disaster to social media disaster, the top Google searches this week covered a wide gamut of themes.
Paris and the whole world looked on in shock as the 856-year-old medieval Catholic cathedral crumbled into ash. The tragic infernal destruction of this tourist attraction of historical and religious significance led South Africans to generate more than 200 000 search queries for “Notre Dame Cathedral” on Monday. Authorities are investigating the cause of the fire that razed the architectural icon.
In other top trending searches on Google this week, radio presenter Siyabonga Ngwekazi, AKA Scoop Makhathini, went viral when it appeared he had taken to Twitter to expose his girlfriend, Akhona Carpede, for cheating on him. Scoop has since come out to say that he was not responsible for the bitter rant and that his account was hacked. “Scoop Makhathini” generated more than 20 000 search queries on Wednesday.
Fans generated more than 20 000 search queries for “Sam Smith” on Tuesday ahead of the the British superstar’s Cape Town performance at the Grand West Casino. Smith ended up cutting his performance short that night due to vocal strain.
Local Game of Thrones superfans were beside themselves on Sunday, searching the internet high and low for the first episode of the American fantasy drama’s eighth season. “Game of Thrones, season 8, episode 1” generated more than 100 000 queries on Google Search on the weekend.
As the festivities kicked off in California with headliners such as Childish Gambino and Ariana Grande, South Africans generated more than 2 000 search queries for “Coachella” on Saturday.
South Africans generated more than 5 000 search queries for “Wendy Williams” on Friday as it emerged that the American talk show host had filed for divorce from her husband Kevin Hunter after 21 years of marriage. Hunter has long been rumored to have been cheating on Williams, which reportedly finally led to the divorce.
Search trends information is gleaned from data collated by Google based on what South Africans have been searching for and asking Google. Google processes more than 40 000 search queries every second. This translates to more than a billion searches per day and 1.2 trillion searches per year worldwide.

5G smartphones to hit 5M sales in 2019
According to the latest research from Strategy Analytics, global smartphone shipments will reach a modest 5 million units in 2019. Early 5G smartphone models will be expensive and available in limited volumes. Samsung, LG and Huawei will be the early 5G smartphone leaders this year, followed by Apple next year.
Ken Hyers, Director at Strategy Analytics, said, “We forecast global 5G smartphone shipments will reach a modest 5 million units in 2019. Less than 1 percent of all smartphones shipped worldwide will be 5G-enabled this year. Global 5G smartphone shipments are tiny for now, due to expensive device pricing, component bottlenecks, and restricted availability of active 5G networks.”
Ville Petteri-Ukonaho, senior analyst at Strategy Analytics, added, “Samsung will be the early 5G smartphone leader in the first half of 2019, due to initial launches across South Korea and the United States. We predict LG, Huawei, Xiaomi, Motorola and others will follow later in the year, followed by Apple iPhone with its first 5G model during the second half of 2020. The iPhone looks set to be at least a year behind Samsung in the 5G smartphone race and Apple must be careful not to fall too far behind.”
Neil Mawston, executive director at Strategy Analytics, added, “The short-term outlook for 5G smartphones is weak, but the long-term opportunity remains huge. We forecast 1 billion 5G smartphones to ship worldwide per year by 2025. The introduction of 5G networks, by carriers like Verizon or China Mobile, opens up high-speed, ultra-low-latency services such as 8K video, streaming games, and augmented reality for business. The next big question for the mobile industry is how much extra consumers are really willing to pay, if anything, for those emerging 5G smartphones and services.”
