Marracuene, Mozambique -- When Preciosa Mondlane looked up from the wreckage of her flooded home in January, she saw a machine circling overhead. "I had no idea what they were there for," she says. "Were they here to help us, or for something else entirely?"
They were there for her. The drone hovering above Ricatla was a visible sign of a partnership initiative among the African Development Bank, Korea, and the Government of Mozambique -- the reason her district emerged from its worst flood in decades without losing a single life.
The rains began in January and did not stop -- weeks of relentless downpour across Maputo and Gaza provinces left the ground no chance to drain. In Marracuene, a district just north of the capital, where the Incomáti River had stayed within its floodplain for as long as anyone could remember, the old line between water and land simply disappeared.
Preciosa held out as long as she could. "I stayed put, clinging to the hope that the water wouldn't dare reach us," she remembers. It came anyway -- "mercilessly" -- swallowing her front door and everything behind it. She took shelter with a neighbour, grateful and humbled: "Even with all the generosity in the world, nothing replaces your own home," she said.
Mayor Ahmad Shafee Sidat surveyed what had become the town's new geography. "All this area you can see down there -- all that green -- was completely underwater, with water levels rising higher than half the height of the houses," he says. "Farmland, everything, turned into a river."
A bet placed before the rains
The drones that appeared over the flood were no accident of timing. Since April 2025, the Drone-Based Disaster Management Project --financed through the Korea-Africa Economic Cooperation (KOAFEC) Trust Fund -- had been building the country's own capability, with a deliberate ambition: not to fly machines over a disaster, but to ensure that the people in a disaster's path had the tools and training to respond themselves.
The Bank's project manager, Lhoucine El Khili, puts it plainly: the goal was never just handing over technology, but transferring the knowledge to use it -- and to keep using it long after the initial support ends.
In barely a year, the project delivered nine drone systems with LiDAR sensors, simulators, unmanned surface vessels and data platforms -- and, more importantly, a cohort of thirty specialists from across government: the weather service, the water directorate, the mapping and roads agencies, and the national disaster institute. None had ever flown a drone.
"Before this project, I had absolutely no experience with drones," says Kátia Manjate, one of the new pilots. Under Korean instructors, she learned to run the entire pipeline, "from data collection all the way to the final product... the processing and understanding what results we can draw from it all." Trainer SunHo Sin watched the same transformation unfold across the whole cohort -- strangers from different ministries learning together how to fly.
Ten of the 30 were being groomed to become instructors. On paper, emergency operations were scheduled to begin in March 2026, following graduation.
The water arrived first.
The final exam nobody scheduled
At the government's request, the half-trained cohort was deployed months ahead of schedule -- effectively taking their final exam in the very disaster the programme was built for. Drones bought as classroom equipment became overnight tools for locating stranded families, mapping washed-out roads, and streaming live imagery to rescue teams who had no other way to see what the water had done.
It was an improvisation no one had planned. It worked. As one Bank representative later put it, that was the moment the project's success became clear: not in a classroom, but in the sky above people who needed to be found.
"Drones are not just equipment," says Rômulo Corrêa, the African Development Bank's Country Manager for Mozambique. "They are tools that help emergency teams arrive faster. They are eyes on the ground when access is difficult. They are critical information that allows action at the right moment. Ultimately, they are instruments in service of people."
The proof is in the district's ledger. "We faced something that had never happened before in Marracuene," Mayor Sidat says. "We managed to record not a single loss of life from the floods." He calls it "a victory" -- and credits the Bank and its partners directly.
What the partnership leaves behind
In July, all 30 pilots graduated with national certification -- ten of them were licensed to train others. What Mozambique has now, 18 months after the first lesson, is not a donated fleet but a standing national capability: technicians from the National Institute of Meteorology (INAM), the agency for disaster risk management (INGD), the Centre for Cartography and Remote Sensing (CENACARTA), the roads administration, and the water directorate, all folded into the country's technical council for disaster response.
For pilot Hermelinda Nhamuche, whose mapping now feeds directly into search and rescue, the project changed her own trajectory too: "I began to fall in love with this world of piloting drones, because it's incredibly important for us, as a society that's growing technologically."
Councilwoman Márcia Moiane noted that the significance extends well beyond this flood. "This project marks a major leap forward -- not only in technology but also in how we respond to emergencies. It means we can act faster and smarter, saving more lives."
In Marracuene, the river no longer respects the old boundaries. But thanks to a partnership that bet on people before the crisis hit, those watching it -- trained, equipped and airborne -- will be ready earlier than ever the next time the water forgets where it is supposed to stop.
