Wu, S., Chen, B., Webster, C. et al. Improved human greenspace exposure equality during 21st century urbanization. Nat Commun

Objective:

  • Generate a global urban greenspace dataset for 1028 large cities

Case:

  • Global cities

Methodology:

  • Population-weighted exposure
  • Gini

Data Source

  • Global urban boundaries
  • Greenspace: Landsat
  • WorldPop
  • NDVI

Findings:

  • Global north cities show a prominently increasing trend in greenspace coverage, including EU, North American, Russia, Austrilia and a few cities of East Asia.
  • Global south cities have a decreasing trend
  • Human exposure to greenspace shows contrasting temporal change trends between global north and global south cities
  • Greenspace exposure inequality has dominantly promoted the improvement
