In demand since time immemorial, increasingly used as intermediate consumption and at the heart of energy and digital transitions, mineral substances are vital to the functioning of economies. While all are important, not all are strategic, and even less so, critical (as lithium). The European Union depends on them. Since 2010, the European Commission has produced statistics evaluating a broad and extensible set of criticality sub-indicators integrated in a two-dimensional matrix (Supply Risk, SR, and Economic Importance, EI) and a list of critical substances based on a combination of SR and EI, updated every 3 years. This article takes a closer look at one of these dimensions, namely the EI one. Our proposed dimension, "Economic effect, EE", integrates cost of using raw materials. Articulated in coherence with EI and assessed over the most recent period, it is compared with EI for lithium. EE suggests a systematically higher criticality than EI. Lithium stands out as 4% more critical. The dynamics of its criticality, on the other hand, is non-monotonic, enriching that of EI. The article also numerically illustrates the prospective use of SR, EI and EE. In addition, an up-to-date overview of lithium (markets, uses, production costs, supply, demand, prices, stocks and trade) has been provided, both for the EU and worldwide.

Rare Earth Elements (REE) are central to the shift towards a green economy because of their unique physicochemical characteristics. These critical materials are both strategic materials that are utilised in wind turbines, solar panels, and electric vehicles among others. Globally, as renewable energy sources are used more frequently, the demand for REEs increases, posing various challenges, especially since China dominates most of the supply chain. This paper examines the REEs and renewable energy consumption in the United States of America (USA), an economic superpower, for the period 1991–2023, using Granger causality tests and other relevant time series techniques. The empirical findings of this paper demonstrate that consumption of REEs causes renewable energy generation, which supports the notion of the centrality of REEs in the development of green energy. Such outcomes underscore the importance of supply chain diversification, the holding of strategic reserves, and the promotion of recycling technologies in order to minimise the risks of supply and ensure a stable transition to clean technologies. These findings can help policymakers design policies for the acquisition of strategic materials and the fostering of sustainable growth of clean energy industries.

Artisanal and small-scale illegal mining, characterized by unregulated and environmentally destructive extraction methods, may pose severe environmental impacts. Heavy metal (HM) contamination from artisanal mining in Southern Hamisana, Sudan, was systematically investigated and evaluated. This study assessed HM concentrations, spatial distribution, sources, contamination levels, and associated health risks in 30 surface soil samples using geochemical analysis, statistical techniques, and risk assessment models. Geochemical analysis revealed mean concentrations of 757, 111, and 27 mg/kg for As, Pb, and Hg, respectively, significantly exceeding global background levels. Pearson correlation and Principal Component Analysis (PCA) were employed to differentiate distinct anthropogenic sources, primarily linked to illegal mining activities, with three components: PC1 (Ni, Cr, Cu); PC2 (As, Hg); and PC3 (Pb, Cd). Pollution indices, including the geoaccumulation index (Igeo) and contamination factor (CF), indicated severe contamination, particularly for As (Igeo up to 5.54, CF up to 108.31) and Hg (Igeo up to 6.28, CF up to 116.25). The ecological risk index (RI) highlighted high ecological risk (RI > 600) for Hg and As, with an average RI value of 1500 and a maximum of 5744 at site G17. Health risk assessments revealed significant non-carcinogenic risks for children, with hazard quotient through ingestion (HQing) values of 3.23E+13 for As and 1.15E+12 for Hg, and carcinogenic risks with total carcinogenic risk (TCR) values of 1.46E+10 for As. This evaluation highlights the urgent need for stringent regulatory frameworks and remediation to counter artisanal mining impacts, offering vital insights for effective management and ecosystem restoration in Southern Hamisana.

This study uses time series analysis of ARDL from 1985 to 2022 to evaluate the impacts of oil extraction volume and Private Participation in Infrastructure (PPI) on China's sustainable economic development. It finds that a 1% increase in oil extraction volume leads to a 0.54% reduction in sustainability in the short term and a 0.41% reduction in the long term. The short-term impact is more pronounced due to immediate environmental costs, though it lessens over time with improved technology and regulations. PPI investments show an insignificant effect on sustainability, likely due to their indirect impact and varying quality. Increased digital device production positively influences sustainability in both the short and long term, while income inequality (GINI index) negatively affects it. In contrast, Small and Medium-sized Enterprises (SMEs) boost sustainability through local economic growth and innovation. Policy recommendations include stricter environmental regulations for oil extraction, promoting digital finance for private investment, tax incentives for green projects, and enhanced ESG reporting.

Illegal gold mining (IGM) is responsible for numerous environmental, social, and economic threats throughout the world. This is also the case in French Guiana (FG), where IGM causes impacts such as deforestation and the contamination of the food chain with methylmercury, among others. Since 2002, to address and mitigate these impacts, the French government has started taking actions and now treats IGM as a real matter of public policy and environmental governance. Despite the growing involvement of various public organizations and scientific communities, numerous challenges linked to the complexity of IGM in the middle of the Amazonian rainforest still result in a gap in applied scientific knowledge partially because of the difficulty to access the field. To improve long-term territorial planning in FG and optimize authority's efforts in terms of risk management, it is first necessary to better characterize and distinguish the different types of IGM practices, to determine their respective impacts on the territory, and to set action priorities. In FG, the existence of an observatory specifically devoted to IGM monitoring represents a unique opportunity to quantitively characterize and classify those activities. This paper presents an in-depth statistical analysis of a georeferenced database provided by this observatory, completed by individual interviews and sites visits. The result is a comprehensive classification of IGM practices in FG into five distinct types of illegal mining sites, based on six criteria (e.g., type of gold deposit, mining techniques), along with their detailed characteristics and inherent variabilities. The proposed classification is structured to distinctly differentiate the nature and the extent of the impacts of these five types of sites. Two of them are particularly detailed in this study, outlining their technical characteristics and their associated variability from site to site. The proposed classification and characterization of IGM in FG are essential for the development of realistic prospective territorial scenarios, and for their impact analysis. Although context-specific, the methodology proposed in this study has the potential to be applied to other countries facing similar IGM related issues, given the presence of equivalent databases or the willingness to create one.

Efforts to recycle waste from the dimensional stone industry are vital due to its environmental impacts, hindered by limited inclusion rates and complex processing needs in current practices. Given the increasing demand for geotechnical fill materials and the depletion of natural soils, sustainable alternatives are necessary. The beneficial use (BU) of Dimensional Stone Processing Industry Wastes (DSPIWs) in geotechnical fills offers a novel solution, yet lacks a comprehensive evaluation. Following the USEPA approach, this study assesses the suitability of DSPIWs—specifically slurry generated in granite, sandstone, and marble processing—for geotechnical fills, examining their potential, relevant lifecycle stages, compatibility with geotechnical fill requirements, environmental concerns, and cost implications. Geotechnical investigations reveal that DSPIWs are non-plastic and non-swelling, with grain size distribution and hydraulic conductivity akin to silty sands. Maximum Dry Density ranges from 1.58 to 1.84 g/cm³ with minimal water-induced variation, and internal friction angles of 44.8° for granite, 40.2° for sandstone, and 36.5° for marble ensure high stability. Electrochemical analysis shows low leachability risks, with pH levels between 7.5 and 8.1 and electrical resistivity above 6200 Ω-cm. Heavy metal concentration in percolation-based leaching tests remains within allowable limits. A cost analysis of a typical embankment section using DSPIWs as fill material reveals a substantial cost reduction of nearly 52 percent compared to using natural soil. Considering the non-hazardous nature of DSPIWs, their compliance with geotechnical fill requirements, minimal environmental and health risks, and economic benefits, this study endorses their BU in geotechnical fills to cater waste disposal problem and advance resource conservation.

The effects of environmental regulation (ER) or resource dependence (RD) on innovation and entrepreneurship have received much attention. However, few studies systematically explore the relationship between ER, RD, and innovation and entrepreneurship within the same framework. This paper aspires to fill this gap in the literature. Using data of 274 Chinese prefecture-level cities from 2009 to 2020, we assess the effects of ER and RD on innovation and entrepreneurship vitality (IEV) through ordinary least squares model and panel threshold regression model. The results show that ER imposes a significant positive effect on IEV under relatively weak RD. Furthermore, ER imposes a significant negative effect on IEV under strong RD. The resource curse also exists in the field of urban innovation and entrepreneurship. Our findings have important implications for the government to implement differentiated ER policies and decrease the city's dependence on natural resources to better promote the development of urban innovation and entrepreneurship.

Over the years, countries across the world have made significant discoveries of various forms of natural resources. The most important, valuable, and problematic of all these discovered resources is arguably oil. This paper investigates the impact that the oil discovery in Ghana in 2007 and its subsequent production has had on the economic growth as well as the unemployment rate of the country. Using the synthetic control method for comparative case studies approach, we exploit the quasi-experimental nature of the discovery which was due to an exogenous shock.

The pivotal role of resource commodities in economic development has heightened attention to price volatility and the resultant price bubble phenomenon. The Generalized Supremum Augmented Dickey-Fuller (GSADF) method is employed to identify explosive episodes in four resource commodities—crude oil, copper, soybeans, and cotton. Furthermore, a rare-event logit model is used to examine the factors influencing these boom-bust episodes. The empirical results reveal multiple price bubbles across the four resource commodity markets from January 1980 to July 2022. The risk of market bubbles is highest in copper, followed by crude oil, cotton, and soybeans. Results for the driving forces of bubbles show that the exuberance and collapse of bubble behavior can be attributed to microeconomic factors and geopolitics. Specifically, global economic expansion and dollar depreciation significantly increase the likelihood of price bubbles. Geopolitical risk exerts a significant influence on price bubbles, which are more likely to be propagated through specific geopolitical acts (GPA) than through geopolitical threats (GPT). Our findings shed new light on the nature and formation of bubbles in the resource commodity markets, providing valuable guidance for policymakers and investors in making informed decisions regarding price management and investment strategies.

Our findings shed new light on the nature and formation of bubbles in the resource commodity markets, providing valuable guidance for policymakers and investors in making informed decisions regarding price management and investment strategies.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"101 ","pages":"Article 105478"},"PeriodicalIF":10.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macroeconomic factors such as coal prices affect corporate decision making. With a set of 39,795 observations of firm-year data, encompassing 30 provinces and spanning the years 2005–2022, this paper estimates the impact of coal price shocks to corporate risk-taking of listed companies in China. The empirical results show that coal prices change negatively affect corporate risk-taking due to internal risk aversion. Further analysis shows that this effect is asymmetric between positive and negative shocks, and is more significant among higher coal dependence provinces. External factors such as economic policy uncertainty further reduce risk-taking. This study provides both macro and micro perspective analysis of corporate risk-taking and coal prices influences, contributing to the policy references for corporate strategic choices and coal price adjustments in the process of energy transition of China.
