Overview

Analysis reveals significant urban-rural differences in cropland loss due to construction land expansion, highlighting implications for food security and sustainability.

Key Points

  • Cropland in urban areas decreased by 44.14%, while rural areas saw a decrease of only 5.97%, indicating severe urban pressure.
  • Construction land increased by 2.61 times in urban areas compared to 90.14% in rural areas, underlining the disparity in development.
  • Geographic Information System (GIS) analysis over 30 years shows that urban cropland conversion to construction land is more pronounced in southern Jiangsu.
  • Differentiated land management policies are necessary to address the significant urban-rural land use changes and ensure agricultural sustainability.
