Long-term anthropogenic land use has profoundly transformed natural environments and impacted climate systems through biogeochemical and biogeophysical processes. Reconstructing historical land-use data is critical for evaluating these effects. However, global studies have precision issues in detailing the peninsula's historical land use. This study reconstructed the temporal dynamics of cropland across the Korean Peninsula over the past millennium, focusing on provincial areas for 1069, 1420, 1590, 1630, 1940, and 2000 AD, using both historical and modern data, and compared the results with the Historical Database of the Global Environment (HYDE). Cropland area trends show a 204.24% increase from 1069 to 1590, a 27.22% decrease from 1590 to 1630, a 74.09% increase from 1630 to 1940, and an 8.23% decrease from 1940 to 2000. Cropland coverage in North and South Korea increased from 1069 to 1940, then diverged, with a decrease in the South and an increase in the North until 2000. Southern and western provinces, with better agricultural conditions, had the highest cropland coverage, exceeding 20%. Social factors like dynastic changes, wars, agricultural policies, and urbanization influenced these changes. Our analysis suggests that the HYDE dataset significantly underestimates cropland on the peninsula, and regional studies could improve global dataset accuracy. |
