Analysis reveals shifting impacts on cultivated land in urbanizing China, suggesting a need for aligned food security governance and land use strategies.

Key Points

This research aims to clarify the mechanisms between population dynamics, cultivated land, and food systems in the context of rapid urbanization in China.
Estimation of cultivated land pressure index at regional, provincial, and prefecture-city scales from 2000 to 2024.
Utilized the Kaya identity and logarithmic decomposition to analyze contributions to changes in cultivated land pressure.
Focused on data from five eastern provinces: Beijing, Tianjin, Hebei, Shandong, and Henan.
Cultivated land pressure exhibited an initial increase, followed by decline and stabilization across the regions studied.
Regional differences revealed distinct patterns of production-consumption differentiation between megacities and major grain-producing areas.
Improvements in cultivated land use efficiency were found to alleviate pressure but showed weakened effects in recent years.
