Development of IO-based model for supply chain risk analysis focusing on Disaster risk at mining sites
Abstract
The large-scale development and diffusion of climate change mitigation technologies is urgently required in our society. These technologies have heightened the need for mineral resources and have shown various negative impacts to the global environment. Behind the supply chain (SC) of mineral resources, mining activities and resource development have resulted in such social risks as human rights abuses and illegal mining. Additionally, environmental risks such as loss of diversity and land-use change around mines is commonplace internationally.However, the impact of these risk factors on the industrial structure of each country through the SC is not fully understood. For this reason, it was not possible to discuss measures to minimize the impact of SC risks in concrete terms.
The aim of our research is to develop a new model that can analyze mineral resource SC risks that affect the flow of resources in each country and industry through the international SC.
We analyzed the relationship between tailings dam failures in the mining sites and the economic activity during 2010-2020. The results showed that the 5 deaths were associated with the 100 billion dollars of economic activity of the Japanese automobile industry.
