South Korean beekeeper calculates the costs of climate change

Park Gyeong Je began tending beehives nearly five decades ago. He did it as a way to earn a living because he enjoyed spending time in the nature. He is now questioning how long he and other farmers will be able to survive due to the changing climate.

The 65-year old runs a beekeeping business in South Korea's Sancheong County, but is also a migratory apiarist, which means he crosses the country with his beehives, chasing seasonal flower blooms. The 'climate change' is causing temperatures to rise, which in turn shortens the seasons. This causes flowers to bloom sooner and for shorter periods. Strong winds have been brought on by the weather changes, making it harder for bees to return to their hives. The bee population has also been affected by new diseases and mites. Farmers feel the seasons directly. "City people do not notice seasons. Park said as he cared for his beehives, "Now it feels like there's only winter and summer left." In 1979, he had eight hives. He now has around 110. Together, the beehives house approximately 8.8 million bees.

Park stated that climate change has made it very difficult for beekeeping farmers.

GLOBAL WORRIES Studies show that climate change is harming bees worldwide, affecting honey production, and many outdoor and indoor crops such as tomatoes, apples, and strawberries, which rely on the insects to pollinate. Yeh Sang Wook, professor of climate and energy systems at Ewha Womans University Seoul, said that a decline in bee populations will affect the food supply. "The fundamental substructure that makes up our natural world, the ecosystem, is in a way being destroyed." According to United Nations data, China was the largest producer of honey in 2018. It was followed by Turkey and Argentina. Honey's taste is a result of the floral nectars that bees collect.

South Korea produces a lot of honey from black locust, which has a mild floral taste. However, there are other varieties, such as chestnut, which has a less sweet, earthier flavour. According to the World Integrated Trade Solution platform, 8.55 metric tonnes of natural honey were exported in 2024.

According to Ministry of Agriculture statistics, the number of beehives used for migratory honeybeekeeping has decreased from 813 279 in 2014 to 813 279 in 2023.

According to the National Institute of Forest Science, the total bee forage in South Korea in 2020 was 146,000 hectares (360,00 acres), which is about 70% less than in the 1970s and 1980s. Researchers from Kangwon National University warned that in January they had conducted a "pilot study" which showed that the pollination activities of South Korean bees would drop by 53.5% on average between 2040-2060, compared to their current levels.

South Korea is joining other countries such as Germany and Greece in launching new urban projects that will boost bees. These include rooftop gardens. South Korea Rural Development Administration (an agency within the Agriculture Ministry) said it planned to introduce smart beekeeping technologies, as well as breed stronger honeybees to withstand climate changes.

More needs to be done

Park transports his bees across the country, stacked in three trucks and one van. He travels mostly at night while the bees are sleeping.

He said that beekeepers share information on where flowers are blooming and where conditions are favorable to determine the best honey-making route.

In the past, there were large climate differences between the southern and central regions. This made it very easy to produce honey. "Global warming has caused flowers to bloom at the same time across the country," he said.

Park releases bees after obtaining the consent of the neighbours. He wears a mesh veil on his hat as he watches them extract nectar from the flowers to bring back to their hives to turn into honey. Park used to travel four times across South Korea in order to collect black locust nectar, but due to premature blooming now only makes two trips and honey is produced for one or two months.

He said that honey production has dropped by 70% compared to 1990s and early 2000s. In the past, it took 20 to 23 day and we harvested eight to nine times. We can only harvest 4 or 5 times.

Park expressed his hope that institutions such as South Korea's agriculture ministry would research and develop technology to improve bee survival during winter and to better manage temperature differences.

The ministry announced that it would invest a total amount of 48,6 billion won (about $32.3 million) in research to restore bee health through 2030.

Park is determined to continue. He plans to expand his beekeeping business by installing smart farming systems, including cameras in the hives that provide real-time updates about the growth of the bee colonies.

He is also training his second daughter to eventually take over the beekeeping business.

As long as I am healthy, I'll keep beekeeping till the day I die. "Even if I died and was born again as a person, I'd still want to become a beekeeper," Park added.
