 The ecological vulnerability of global protected areas is linked to the 2030 United Nations Sustainable Development Goals, and a novel degree of ecological vulnerability index was developed based on Big Earth data to assess this vulnerability in case studies of international union for conservation of nature par in various basins. The spatial pattern of ecological vulnerability in these areas was relatively stable between 2001 and 2015, with the Caspian Sea Basin and protected landscape seascape showing high vulnerability while the Black Sea Basin and wilderness areas showed low vulnerability. Big Earth data shows great vitality in piecological vulnerability assessment and strengthening international cooperation is important to address environmental and resource challenges in these important international basins.
