This paper quantifies the effects of material price and availability shocks on the power sector across permutations of fossil fuel and electricity capacity cost assumptions. Our findings reveal that extreme price shocks in major metals are the most disruptive to power system development; minor metal disruptions, taken together, can also have an equal impact when strictly unavailable. In response, the system adapts by prolonging the operation of existing capacity rather than investing in new infrastructure, thereby exacerbating reliability, economic, and environmental outcomes. This research underscores the importance of moving beyond traditional, static methods of assessing energy system resilience to a dynamic approach that considers the interactions between material availability, cost, and system evolution. These findings have significant implications for policymakers and industry stakeholders, stressing the need for proactive risk management strategies across supply chains that are often overlooked in planning.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105607"},"PeriodicalIF":10.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170097","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}

One of the key issues is the determination of the optimal cut-off grade that ensures economic viability. Nickel, as one critical commodity in the renewable energy supply chain, adds another layer of complexity, as its prices fluctuate in uncertain market conditions. These price fluctuations further intensify the challenge of selecting the most economically viable cut-off grade. This research develops a cut-off grade optimization model in an open-pit mining of laterite ores, as the main source of nickel commodities. The proposed cut-off grade model considers two product options, i.e. pure nickel and ferronickel. The uncertainty in selling prices is presumed to follow to the Geometric Brownian Motion (GBM) function. The cut-off grade model is mathematically formulated and analytically solved using derivatives analysis to achieve the global optimal solution. There are two scenarios to be analyzed, which include deterministic and stochastic scenarios. Numerical examples indicate that the proposed model can effectively optimize the cut-off grade value to obtain the maximum profit for both scenarios. An analysis of three scenarios—most likely, pessimistic, and optimistic—shows that fluctuations in selling prices significantly affect both profit and Net Present Value, with the effect amplifying at lower optimal cut-off grades. This finding highlights the importance of flexible decision-making in mine planning to maintain financial stability under the presence of market uncertainties.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105630"},"PeriodicalIF":10.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168265","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}

Amidst the global demand for heightened human rights due diligence (HRDD), collaborative and Indigenous-led Human Rights Impact Assessments (HRIA) emerge as a crucial tool to further the implementation of FPIC and HRDD at the corporate level. Given that there is still little literature on such HRIA, our systematisation of Repsol's experience on Wayuu territories in Colombia is a timely contribution to filling some of the practical gaps.

By raising the question of what or who defines what is “appropriate” for artisanal miners, the paper engages critically with the ignored and complicated spatial and temporal dynamics that underpin miners’ decisions regarding technologies and the impact of these choices on the political ecology of artisanal gold mining. Until recently, technologies used by small and artisanal miners have been known to be crude and rudimentary, with deleterious impacts on the natural environment. Hence, the policy drive to formalise illegal miners has emphasised the essence of appropriate technologies, depoliticizing the complex underpinning factors that shape technology adoption and rejection. Thus, the paper focuses on two technologies that have become prevalent in the artisanal mining scene in Ghana, i.e. the Chinese Changfa and the Trommel, to demonstrate the complex and myriad ways miners determine which technology is appropriate. Appropriate technologies, the paper argues, are determined based on a multifaceted combination of socio-political, economic, ecological, biophysical and cultural factors. The paper concludes by discussing the implications of these observations on the formalisation of artisanal miners amid the increasing demand for energy transition minerals in developing economies.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105641"},"PeriodicalIF":10.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137748","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}

It uses empirical data collected in household surveys conducted around Kahuzi-Biega National Park and Itombwe Nature Reserve in the South Kivu province in a hurdle regression model to show that mining is used as both complementary and substitutory to farming. Results indicate that households that use mining to complement their farming activities tend to experience higher food security compared to non-mining households. As the reliance on mining increases, households tend to cultivate less land. These findings can help to inform actions against the prevalent issue of food insecurity in the region, but also point to dilemmas and trade-offs among environmental and development goals.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105613"},"PeriodicalIF":10.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115902","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}

At the time, Japan had relied primarily on China for its imports of rare earth metals, raising speculations that China would impose a targeted retaliation against Japan and cause a significant increase in rare earth metal prices for Japan. Contrary to this forecast, this research shows that the dispute did not lead to a targeted impact on Japan; rather, China's decisions during the time of the dispute ultimately led to a global spike in the price of rare earth metals. Additionally, our empirical analysis suggests that international cooperation, particularly the WTO verdict in 2014, played a critical role in stabilizing prices and mitigating the initial price shocks caused by the dispute. Since then, Japan and other importers of rare earth metals have begun shifting their strategies of procuring rare earth metals by lowering their reliance on China. However, their strategies have not ultimately led to a successful diversification as importers still rely heavily on a select few source countries of rare earth metals, mainly China and Vietnam. Further, China retains its dominance as the primary processor of rare earth metals, leveraging protectionist-like policies to control global supply. As such, skewed market power over a single or limited suppliers of rare earth metal still poses substantial trade risks to importers. This paper presents strategies for importing nations of rare metal earth metals to better mitigate such risks.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105631"},"PeriodicalIF":10.2,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105633","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}

This study outlines a methodological framework for quantifying the intranational risk profile of critical mineral sectors and compares them with the sector's international potential for leverage. The four intranational factors of concentration, synchronization, private sector involvement, and regulatory obstacles were analyzed across multiple scales in order to determine an intranational risk score that quantifies the resilience or fragility of the critical mineral sector in question. Network analysis was also separately conducted to identify the most important entities operating across all critical mineral sectors. Finally, this study assessed the critical mineral sector's global share of reserves and production to determine an international risk score that quantifies the country's critical mineral sector's leverage potential. A case study of India showed that two critical mineral sectors with high leverage potential, chromite and barite, were respectively intranationally resilient and fragile. Of the remaining sectors with minimal leverage, five sectors such as aluminum were intranationally resilient and may serve as viable mitigation options for future critical mineral supply. Three sectors such as titanium were intranationally fragile, but recent regulatory developments may both decrease intranational risk and increase international risk, potentially making them major critical mineral sectors in the future.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105625"},"PeriodicalIF":10.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105632","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}

This study employs the autoregressive distributed lag model (ARDL) to estimate the underlying long-run and short-run relationships between the variables. The study uses three proxies of governance quality, namely autocracy, executive recruitment, and democracy, and estimates three regression models. Furthermore, interaction terms are included to explore how different forms of governance quality influence the economic impact of natural resources. The results confirmed a long-run equilibrium relationship among the variables included in the estimated models. The results further show that the impact of natural resource rents on economic growth depends on the model specification. It is also time-variant, depending on whether the model is estimated in the short run or the long run. Overall, our results do not support the existence of the resource-curse phenomenon in Zambia, regardless of the time frame considered. Instead, the results indicate that natural resources have the potential to spur economic growth in the short run when both executive recruitment and democracy are used as governance proxies, and in the long run when democracy is used. The results also show that governance modulates the impact of natural resource rents on economic growth, but only when proxied by democracy. However, the findings vary depending on the timeframe. While democracy positively influences growth through natural resources in the long run, it has adverse effects in the short run. The results of the study suggest that policymakers in Zambia should enact cautious measures that encourage responsible approaches to utilizing natural resource rents to foster sustainable economic growth. This involves using natural resource rents to boost human and physical capital, as well as diversify the economy.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105603"},"PeriodicalIF":10.2,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083859","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}

Methodologically, the method of moments quantile regression approach was employed in deriving the study's main inferences. Also, the dynamic common correlated estimation technique was applied for robustness. Empirically, the paper demonstrated that in African economies with relatively high levels of energy poverty intensity, resource endowments have a weak effect in propelling the former. However, natural resource rents are more important to exacerbate energy poverty in African countries with relatively more moderate energy poverty severity than those with low intensity. As a national-level economic factor, while income has an insignificant effect irrespective of energy poverty intensity in the African economies, public outlay substantially aggravates across all energy poverty intensity classifications by the same magnitude. However, infrastructure development reduced energy poverty more in economies with relatively low energy poverty severity, followed by moderate and high-intensity nations. Also, population growth's adverse impact was most dominant in the low-energy-poverty-intense countries, followed by the medium- and high-energy-poverty-severe economies.
