Abstract Long-term effects of massive building material use in China, which experienced intense urbanization in the past two decades, remain insufficiently explored. Here, to fill these gaps, we developed a high-resolution time-series database of building material stocks from 2000 to 2019 and found that China held 15% of the global stock, which accounted for 19% of the country’s total carbon emissions.

Abstract The escalating trend of global hillside urban expansion threatens terrestrial biodiversity and undermines global initiatives, including the Sustainable Development Goals and the Global Biodiversity Framework. This study addresses a critical knowledge gap by examining the impacts of hillside urban expansion on terrestrial biodiversity across multiple scales, integrating multi-source high-resolution data with terrestrial vertebrate species datasets.

Urbanization and industrialization represent largely a process of transforming materials from biosphere and lithosphere to anthroposphere. Understanding the patterns of such anthropogenic material stock accumulation is thus a fundamental prerequisite to assess and sustain how humans alter the biophysical movements of resources around Earth. Previous studies on these anthropogenic stocks, however, are often limited to the global and national scales, due to data gaps at higher spatial resolutions.
