Nepal is currently utilizing unmanned aircraft to navigate destroyed infrastructure and deliver emergency aid following catastrophic flash floods. these drones are operating in regions such as Nuwakot and Dhading to locate survivors and retrieve deceased victims from areas ground crews cannot reach.
From the 2015 Earthquake to Today's Flood Response
The deployment of unmanned aircraft in Nepal is not a new experiment but an evolution of a strategy born from tragedy. According to the report, international relief agencies first introduced drone technology to Nepal following the 7.8-magnitude earthquake in 2015, which caused widespread destruction in Kathmandu and surrounding regions. At that time, the focus was primarily on damage assessment and searching for survivors among the rubble.
Since that disaster, the role of drones has shifted from simple observation to active logistics. In the current flood crisis, the technoloogy has transitioned into an "indispensable part of the humanitarian toolkit," particularly for the rugged, mountainous terrain of Nepal where landslides frequently erase the only existing access roads. This progression reflects a global trend where drones are moving from military and surveillance roles into specialized humanitarian logistics.
The DJI FlyCart 100's 85-Kilogram Payload
The current operation relies heavily on specific industrial hardware to overcome the geography of the flood-hit districts. An eight-member drone team is utilizing the DJI FlyCart 100, a Chinese-made heavy-lift cargo drone. As reported, this specific model is capable of transporting logistics weighing up to 85 kilogrammes over a range of 4 kilometres, allowing it to ferry food and medicine to isolated villages that are otherwise cut off from the rest of the country.
Beyond cargo, the mission employs thermal drones designed to detect heat signatures of living people. This capability is critical in the search for the nearly 4,000 individuals currently listed as missing. By scanning inaccessible slopes and debris fields, these thermal sensors provide a layer of intelligence that ground-based search-and-rescue teams in Nepal simply cannot match given the unstable terrain.
Searching the Upper Trishuli-1 Hydropower Tunnel
One of the most harrowing applications of this technology is occurring at the Upper Trishuli-1 hydropower project. drone operators have flown unmanned aircraft inside the project's tunnels, where scores of workers are believed to be trapped following the flash floods. in these confined, dangerous spaces, drones serve as the only eyes for rescuers, providing real-time data on the condition of the tunnel and the location of potential survivors.
The grim reality of the disaster was most visible in Dhading, where residents witnessed a drone transporting a human body from a region too dangerous for rescuers to enter on foot. This use of drones for body recovery highlights a shift in humanitarian operations: when the risk to rescuers becomes too high, unmanned systems are now the primary means of providing closure to families.
The Gap Between 1.6 Million Affected and Limited Payload
Despite the technological success, the scale of the disaster in Nepal dwarfs the current drone capacity. With approximately 1.6 million people affected and nearly 1,100 confirmed dead, the limited payload and range of the DJI FlyCart 100 mean that drones can only provide targeted relief rather than a systemic solution. The report notes that operators still struggle with weather conditions and payload restrictions that limit the volume of aid delivered.
Several critical questions remain unanswered regarding the long-term coordination of these efforts. It is unclear which specific international or government agencies are funding the procurement of the DJI fleet, and the report does not specify how the Nepalese government plans to integrate this technology into a permanent disaster response framework. Furthermore, while the report mentions "restrictions" in weatheer, it does not detail how the team intends to operate if the monsoon rains intensify, which typically grounds most small-to-medium unmanned aircraft.
