Effect of income, industry structure and environmental regulation on the ecological impacts of mining: An analysis for Guangxi Province in China.

Mineral resource extraction is often accompanied by severe environmental pollution and ecological damage, hindering mining economies from achieving sustainable development. This paper aims to promote the goal of cleaner production in extractive industries from the perspective of environmental management through a more accurate understanding of how human activities affect the extractive industries. This requires more granular data for environmental damage in mining. The article proposes an ecological threat assessment framework for mining to support sustainable processes in the extractive industry. It integrates biophysical variables, technical indicators, and human activity data. The study is based on data at the mine level with 17 indicators used to evaluate the ecological impact of 13960 mines in Guangxi, China, from 2008-to 2018 in four dimensions: economic and technical indicators of mines themselves, surrounding economic activity, geological and environmental vulnerability, and ecological status of mining sites. Data from multiple sources were used to assess, map, and monitor ecological impacts in mining areas, such as high-resolution satellite images, interview data, environmental assessment reports, and mining rights data. We evaluated the ecological impact level of each mine and the extent to which spatial heterogeneity of regional economic and environmental preferences affected the degree of ecological impact. The results show that growth in population income has changed environmental preferences and driven down environmental disturbances in mines. Reduced dependence of regional economies on the industrial sector has also contributed to environmental improvements. In addition, increasing environmental regulation has limited the ecological impacts of mining, but these environmental regulation impacts are regionally heterogeneous. The effect of laws and rules is lower in cities and regions dependent on mineral resources, where resource extraction companies have more bargaining power. The results of this study will inform environmental management in the mining sector and support sustainable development in the region. [Display omitted] [ABSTRACT FROM AUTHOR]
