摘要

Economic globalization, while fostering widespread economic development, has concurrently intensified water scarcity risks (WSR), particularly for water-intensive sectors like mining and quarrying. Assessing water scarcity risk induced by local water scarcity in mining and quarrying, along with their propagation to downstream region-sectors via supply chains, is of critical importance. Despite its significance, this aspect remains unclear in current discourse. To understand the transmission of WSR in mining and quarrying, this study begins by evaluating LWSR, incorporating considerations for local sustainable water management requirement. Subsequently, we investigate its transmitted based on multi-regional input-output model. Results reveal that the LWSR in mining and quarrying sector amounted to $62 billion in 2020, potentially causing an additional loss of $265 billion through domestic and international trade systems. Notably, the petroleum, chemical, and non-metallic mineral products sector emerges as the highest contributor to the transmission of water scarcity risk. Crucially, results of this study reveal inequality in how water scarcity risk spreads across countries situated in different geographical regions and income groups, providing insights for policymakers to shape inclusive policies for mitigating water scarcity risk.
