South Korea is facing its worst heatwave in years, prompting President Lee Jae Myung to declare it a national disaster. With temperatures reaching a staggering 42.5°C in Yangsan, the death toll has risen to 21 as authorities scramble to protect vulnerable populations, particularly elderly farmers.23
To combat the extreme heat, North Gyeongsang Province has deployed drones equipped with loudspeakers and thermal imaging cameras to warn farmers to take breaks and avoid prolonged exposure. These drones can travel up to 5 kilometers and broadcast messages like "Do not work for long hours" and "There is a heatwave alert, so be careful."4
The province, which accounts for 16.7% of South Korean farming households, has a significant elderly population, with 59.2% of farmers aged 65 and older. The heatwave has already led to a 30% decrease in crop yields compared to last year, raising concerns about food security.7

In addition to the human toll, the heat has devastated livestock, with approximately 17,140 animals reported dead. The situation is dire, as the Interior and Safety Ministry reported 2,220 cases of heat-related illnesses since mid-May, with 19 fatalities attributed to the heat.
As the crisis unfolds, local leaders are also broadcasting heat warnings, but many farmers remain unaware while working in the fields. The use of drones represents a significant technological advancement in addressing this public health emergency.8
“North Gyeongsang Province, which accounts for 16.7% of South Korea's farming households, uses drones with thermal cameras to broadcast alerts to elderly farmers, who make up 59.2% of the province's farming population. The heatwave has also killed about 17,140 livestock and 160,000 farmed fish since mid-May.”
