Implication

Randomized trial evaluates the impact of population aging and land use on agricultural sustainability in China, suggesting integrative policies are essential.

Key Points

  • This study aims to enhance agricultural sustainability by integrating demographic and land-use factors into a unified model.
  • Developed a multidimensional assessment model combining system dynamics and energy value analysis.
  • Analyzed population structure evolution, land-use patterns, and agricultural production systems.
  • Focused on China as a case study with projections until 2050.
  • Projected a 62.7% decline in agricultural labor intensity and a 12.76% increase in capital intensity by 2050.
  • Observed cropland fragmentation increase from 0.45 in 2006 to 0.58 in 2020, indicating intensifying land use pressures.
  • Predicted a potential trend toward land consolidation around 2040 due to rural-urban migration.
