Overview

Quantifies cropland abandonment rates in the Yangtze River Economic Belt, proposing optimal reuse strategies for underutilized land, suggesting improved food security.

Key Points

  • To quantify cropland abandonment in the Yangtze River Economic Belt and propose optimal reuse strategies.
  • Quantified cropland abandonment from 1990 to 2020 in the Yangtze River Economic Belt.
  • Developed a bottom-up abandonment risk assessment framework.
  • Projected future abandonment scenarios and optimal strategies for cropland reuse.
  • Average annual cropland abandonment rate of 6.48% from 1990 to 2020.
  • Projected potential abandonment of 20,600 km² by 2030, reaching 12.46% of total cropland.
  • Optimal strategy suggests allocating 45.71% of underutilized land to agriculture and 54.19% to ecological uses.
