[HGG01-02] Understanding and classifying spatial patterns of global eco-environmental vulnerability
Keywords:global eco-environmental vulnerability, human and nature, environmental sustainability
Anthropogenic processes cause profound changes to natural systems and result in a consistent decline in the quality of eco-environment. In this paper, a framework that aims to qualify eco-environmental vulnerability levels over the global scale has been presented for decision making. The global map of eco-environmental vulnerability was generated by using easily accessible datasets. The vulnerability is classified into six levels consisting of potential, light, slight, medium, heavy, and very heavy. Eco-environmental vulnerability tends to be high and very high in Asia and Africa with leading countries China, India and Ethiopia. Spatial patterns of eco-environmental vulnerability are driven by human and natural disturbances including socioeconomic, natural hazards, hydrometeorology, topography and land resources, among which population growth and natural hazards are the key drivers. PM2.5 that can be considered as a hazardous substance in the human environment and an anthropogenic disturbance associated with nature and human-made influence was selected to validate the global eco-environmental vulnerability map. It is demonstrated that global eco-environmental vulnerability map has high correlation with PM2.5 distribution patterns with correlation coefficient approximately 0.82 based on 100 validating points. Outcomes of this study include the mapping of global eco-environmental vulnerability and eco-protection zones that provide key hotspots of eco-environmental vulnerability at global scale for informing the decision makers and the people to take actions to lessen the disturbances and achieve environmental sustainability
