What South Korea’s 87% Drop in Aquaculture Heat Losses Really Measures
South Korea reported an 87 percent drop in aquaculture losses from high water temperatures in 2025. But data from major black rockfish farming waters show that local heat exposure, early harvest and emergency releases changed alongside farm protection.

South Korea’s Farmland Census Tests the Future of Farming
The first nationwide farmland census is designed to expose speculation and misuse. But the harder question begins afterward: who will farm the land, under what terms, and whether it can remain productive in an aging, climate-stressed countryside.
