Based on international best practices and legal requirements for mine closure, an Integrated Mine Closure Planning Adherence Index (IMCPAI) was developed and applied to 8 closure plans from iron mines located in Brazil. The IMCPAI is a weighted checklist comprising 21 requirements, distributed across four categories: (i) knowledge base, (ii) integrated mine closure planning, (iii) stakeholder engagement and economic and social transition, and (iv) execution of closure actions. The performance of each category was evaluated, and the respective adherence level was calculated. The majority of the mines demonstrated a moderate adherence to IMCP evaluated. The integrated closure planning category achieved the best overall performance, suggesting a significant gap between theoretical principles and practical application of mine closure on the other analyzed categories. The IMCPAI proposed in the present study has the potential to enhance the quality of mine closure plans.

In Ghana, for example, mining-related environmental challenges led to a total ban on ASM activities in 2017. In light of this, the government of Ghana launched a programme dubbed the ‘Community Mining Scheme’ (CMS), premised on multi-stakeholder cooperation, as an alternative to illegal mining. Recently, however, the new (NDC led) government has disbanded the scheme, proposing to replace it with a new scheme – mining cooperatives – which are also expected to be operationalised by local mining communities and other stakeholders. Thus, this study employs a stakeholder analysis framework to examine the roles and agency of the various stakeholders expected to operationalise the framework and structure of the new scheme. We delineate ways by which mining authorities can tap into the synergies of the various stakeholders in order to achieve sustainable mining practices. We conclude by encouraging future research to go further to place the CMS discussion more accurately into the context of how far the project grew, and possibly explore the challenges that confronted the project, so as to provide insights that could either help reshape policy or refine ideas about the new ‘mining cooperatives’ scheme.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105610"},"PeriodicalIF":10.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912200","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}

The study employs the system Generalized Method of Moments and establishes three main results. First, military spending is negatively affected by coal, forest, mineral, and natural gas rents but positively affected by oil rents. Second, institutional quality plays a role in the link between NRR and military spending, mainly through corruption. Third, robustness checks indicate that all these results are sensitive to country characteristics but robust to the instrumental variable two-stage least squares and Driscoll and Kraay's fixed effects methods. Additionally, the use of forest and natural gas rent to finance military spending is driven by several factors, including cross-border conflicts, economic risk, ethnic tensions, military involvement in politics, external debt risk, and inflation risk. Therefore, reforms of military institutions in SSA are essential, and they should consider respect for universal standards of public spending and the fight against corruption. In this sense, the preparation and execution of military expenditures must be subject to administrative, parliamentary, and jurisdictional controls. Creating anti-corruption units within the ministries responsible for Defence and Security is strongly encouraged. Besides, diplomatic efforts in conflict resolution, economic development measures, and risk management policies could help reassess priorities regarding defence spending.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105609"},"PeriodicalIF":10.2,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908272","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}

So-called “conflict minerals”— typically tin, tantalum, tungsten, and gold (3TG) associated with Democratic Republic of Congo — have been a target for responsible sourcing since 2008. As production of most raw materials has increased, there is need to pay attention to sourcing from conflict-affected or high-risk areas which poses various risks and consequences. To support sustainable and responsible use, companies seek to identify and manage potential risks. Existing tools and initiatives are limited in supporting companies' sustainability goals, as many are generic or are not publicly accessible. This article introduces an open-access tool that provides a product focus, the ConflictRisk method, which assesses the risks associated with sourcing raw materials from conflict-affected and high-risk areas at the country level using publicly available data. Building upon the existing GeoPolRisk framework, this method replaces the governance indicator with the INFORM Risk Index, which provides a direct measure of armed conflict. The ConflictRisk method was demonstrated in a case study considering 52 raw materials imported into the United States, and revealing risks even for materials sourced from outside traditionally recognized high-risk areas. Differences between the ConflictRisk method and existing frameworks, such as the European Union's conflict mineral regulations, underscore the value of a quantitative assessment. The article also presents a framework for integrating the ConflictRisk method into Life Cycle Sustainability Assessment to characterize the impacts of conflict risks. Limitations of the method include its reliance on national-level data, which can restrict the granularity of conflict risk evaluations at the sub-national level. The study also emphasizes the need for comprehensive supply chain analysis and further research to refine the integration of conflict risk into broader sustainability assessments.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105605"},"PeriodicalIF":10.2,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902448","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}

While conceptually distinct, in practice these licences interact. Communities and protest movements which bestow or withdraw social licence may also exert pressure on regulators, or influence economic licences through boycott and divestment campaigns. In this paper, we examine the pressures which affect business risk through the multiple dimensions of the “licence to operate,” in the case of federally regulated mines in Australia. Studying 409 mining applications that were under regulatory review, approved, or withdrawn between 2000 and 2020, we use competing risk hazard models and linear regressions to examine how measures of business risk (longer times in review and more conditions) and choices to withdraw are affected by: the attributes of the mine, competing rights claims and land-uses, levels of oppositional mobilization, changes in political parties in power, and market prices. We found that new projects, and those that triggered an independent assessment of their impact on water, were likely to experience longer reviews. Mines where agriculture was the competing land use also faced longer reviews, and mine proponents were more likely to withdraw their proposal. Contrary to our expectations, the mobilization of opposition to a mine was associated with faster time to approval, but also a higher number of conditions.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105578"},"PeriodicalIF":10.2,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898601","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}
