The mining industry (MI) in mineral-rich regions is pivotal for economic growth but is challenged by significant pollution and emissions. This study examines Guangxi, a representative region in China, in light of the country’s “Dual Carbon” goals. We quantified carbon emissions from the MI from 2005 to 2021, employing the generalized Divisia index method (GDIM) to analyze the factors driving these emissions. Additionally, a system dynamics (SD) model was developed, integrating economic, demographic, energy, environmental, and policy variables to assess decarbonization strategies and the potential for carbon decoupling. The key findings include the following: (1) Carbon accounting analysis reveals a rising emission trend in Guangxi’s MI, predominantly driven by electricity consumption, with the non-ferrous metal mining sector contributing the largest share of total emissions. (2) The primary drivers of carbon emissions were identified as economic scale, population intensity, and energy intensity, with periodic fluctuations in sector-specific drivers necessitating coordinated policy adjustments. (3) Scenario analysis showed that the Emission Reduction Scenario (ERS) is the only approach that achieves a carbon peak before 2030, indicating that it is the most effective decarbonization pathway. (4) Between 2022 and 2035, carbon decoupling from total output value is projected to improve under both the Energy-Saving Scenario (ESS) and ERS, achieving strong decoupling, while the resource extraction shows limited decoupling effects often displaying an expansionary connection. This study aims to enhance the understanding and promote the advancement of green and low-carbon development within the MI in mineral-rich regions. Full article

Background: Addressing undernutrition and malnutrition requires a multi-pronged approach targeting different populations with appropriate interventions. Knowledge and perception (K&P) of Individuals and communities about nutrition to human health relationship/continuum is a prerequisite for addressing malnutrition in rural and mountain communities. Assessing K&P is essential for developing strategic interventions to up-scaling K&P of communities and achieving nutrition security. Homestead gardens are a proven intervention for achieving nutrition security for all family members of gardeners. Methods: This paper includes homestead gardeners from the Himalayan Mountain Region (HMR) as respondents. We developed a scale to assess the K&P of respondents, based on ratings from 20 judges. A total of 134 issues/items have been retained in the scale from macronutrients, micronutrients, minerals, and vitamins. A framework has also been developed and adopted for the study. A knowledge and perception index (KPI) has been developed based on the respondents’ responses. We have reviewed and analysed the national policy interventions for augmenting the K&P of the study community to achieve nutrition security. Results: The nutrition K&P of respondents are inadequate and far from the desirable level. Policy review and analysis indicate that the creation of K&P in the community to contribute to self and family nutrition security was previously highly neglected. Conclusions: The policy process of national, state, and county/district-level development sectors in developing countries under the HMR may take the initiative to ensure self-nutrition security by creating K&P of the community on nutrition issues. The designed scale is prudent requires testing and validation for measuring farmers’ K&P on nutrition, which may be adopted in future studies and policymaking not only nationally but also from an international perspective.

The blockchain technology is transforming the mining industry by enabling mineral reserve tokenization, improving security, transparency, and traceability. However, controlling access to sensitive mining data remains a challenge. Existing access control models, such as role-based access control, are too rigid because they assign permissions based on predefined roles rather than real-world conditions like mining licenses, regulatory approvals, or investment status. To address this, this paper explores an attribute-based access control model for blockchain-based mineral tokenization systems. ABAC allows access permissions to be granted dynamically based on multiple attributes rather than fixed roles, making it more adaptable to the mining industry. This paper presents a high-level system design that integrates ABAC with the blockchain using smart contracts to manage access policies and ensure compliance. The proposed model is designed for permissioned blockchain platforms, where access control decisions can be automated and securely recorded. A comparative analysis between ABAC and RBAC highlights how ABAC provides greater flexibility, security, and privacy for mining operations. By introducing ABAC in blockchain-based mineral reserve tokenization, this paper contributes to a more efficient and secure way of managing data access in the mining industry, ensuring that only authorized stakeholders can interact with tokenized mineral assets.

This study presents a methodology developed in collaboration with the Colombian National Mining Agency, aimed at enhancing the economic and productive activity of small-scale miners in Colombia through the promotion of associativity. Despite persistent challenges in the formalization and sustainable development of the artisanal mining sector, fostering associative models offers a pathway towards a more sustainable mining industry, aligned with current national policies. The proposed roadmap, designed to achieve this objective, is divided into three sequential phases. The first, the Baseline Survey, focuses on comprehensively understanding the initial socio-economic and operational conditions of mining communities. This is followed by Participatory Strategic Planning, which involves projecting the long-term role and development of mining associative figures. Finally, the Annual Operational Planning and Execution phase concentrates on the concrete implementation of activities designed to achieve sustainable organizational goals. During the design and initial implementation of this roadmap, we found that continuous support and tailored training programs are essential for mining communities. These programs are critical for fostering the development of collective skills and strengthening community ties within mining organizations. The findings highlight that by strengthening collective capabilities and community ties, mining organizations can enhance their self-management capacities and significantly contribute to the economic development of their regions. This approach addresses key challenges in the sector by promoting a more organized and resilient operational framework. The implementation of a participatory methodology, coupled with specific organizational strengthening programs, coordinated execution, and continuous monitoring, provides a viable route towards a more sustainable and formalized small-scale mining sector in Colombia. This roadmap offers a practical framework for fostering self-managed and economically contributing mining organizations. Full article

Electric passenger vehicles are set to dominate the European car market, driven by EU climate policies and the 2035 ban on internal combustion engine production. This study assesses the sustainability of this transition, focusing on global warming potential and Critical Raw Material (CRM) extraction throughout its life cycle. The intensive use of CRMs raises environmental, economic, social, and geopolitical concerns. These materials are scarce and are concentrated in a few politically sensitive regions, leaving the EU highly dependent on external suppliers. The extraction, transport, and refining of CRMs and battery production are high-emission processes that contribute to climate change and pose risks to ecosystems and human health. A Life Cycle Assessment (LCA) was conducted, using OpenLCA software and the Ecoinvent 3.10 database, comparing a Peugeot 308 in its diesel and electric versions. This study adopts a cradle-to-grave approach, analyzing three phases: production, utilization, and end-of-life treatment. Key indicators included Global Warming Potential (GWP100) and Abiotic Resource Depletion Potential (ADP) to assess CO₂ emissions and mineral resource consumption. Technological advancements could mitigate mineral depletion concerns. Li-ion battery recycling is still underdeveloped, but has high recovery potential, with the sector expected to expand significantly. Moreover, repurposing used Li-ion batteries for stationary energy storage in renewable energy systems can extend their lifespan by over a decade, decreasing the demand for new batteries. Such innovations underscore the potential for a more sustainable electric vehicle industry. Full article

Municipal solid waste (MSW) and refuse-derived fuel (RDF) incineration generate over 20 million tons of residues annually in the EU. These include bottom ash (IBA), fly ash (FA), and air pollution control residues (APCr), which pose significant environmental challenges due to their leaching potential and hazardous properties. While these residues contain valuable metals and reactive mineral phases suitable for carbonation or alkaline activation, chemical, techno-economic, and policy barriers have hindered the implementation of sustainable, full-scale management solutions. Accelerated carbonation technology (ACT) offers a promising approach to simultaneously sequester CO₂ and enhance residue stability. This review provides a comprehensive assessment of waste incineration residue carbonation, covering 227 documents ranging from laboratory studies to field applications. The analysis examines reactor designs and process layouts, with a detailed classification based on material characteristics, operating conditions, investigated parameters, and the resulting pollutant stabilization, CO₂ uptake, or product performance. In conclusion, carbonation-based approaches must be seamlessly integrated into broader waste management strategies, including metal recovery and material repurposing. Carbonation should be recognized not only as a CO₂ sequestration process, but also as a binding and stabilization strategy. The most critical barrier remains chemical: the persistent leaching of sulfates, chromium(VI), and antimony(V). We highlight what we refer to as the antimony problem, as this element can become mobilized by up to three orders of magnitude in leachate concentrations. The most pressing research gap hindering industrial deployment is the need to design stabilization approaches specifically tailored to critical anionic species, particularly Sb(V), Cr(VI), and SO₄²⁻.

Proton pump inhibitors (PPIs) are widely prescribed medications primarily used to treat gastroesophageal reflux disease, peptic ulcer disease, and upper gastrointestinal bleeding. Despite clear therapeutic benefits in appropriate contexts, widespread overprescribing and extended use without clear indications have prompted significant concerns about associated risks. Accumulating evidence, predominantly from observational studies, suggests that long-term PPI use may lead to complications such as vitamin and mineral deficiencies, increased risks of infections, dysbiosis, renal dysfunction, bone fractures, cardiovascular disease, and certain malignancies. This narrative review not only synthesizes the current evidence surrounding PPI-related harms and existing deprescribing guidelines but also offers a novel perspective on how stewardship principles can be applied to promote responsible PPI prescribing. In particular, we propose a stewardship-oriented deprescribing framework rooted in implementation science, focusing on provider behavior, patient engagement, and health system-level integration. Recognizing these potential harms, evidence-based deprescribing strategies such as tapering, intermittent dosing, and transitions to alternative therapies are critical to mitigate unnecessary patient exposure. Effective implementation of deprescribing requires addressing patient, provider, and institutional barriers through educational initiatives, policy support, and structured monitoring. By promoting judicious PPI prescribing and proactive stewardship practices, clinicians can significantly reduce medication-related harm and improve patient safety. Full article

Donkey milk has received increasing attention in recent years due to its unique nutritional composition and potential biological activities. This comprehensive review analyzed the main nutritional components of donkey milk, including proteins, lipids, carbohydrates, vitamins, and minerals, while also examining its significant biological activities such as antioxidant, antimicrobial, immunomodulatory, and anti-inflammatory properties. The protein profile of donkey milk is notable for its high proportion of whey proteins (55–65%), resembling human milk more closely than cow milk. Its relatively low-fat content (approximately 1.29%) with higher proportions of unsaturated fatty acids provides nutritional advantages for specific dietary needs. The carbohydrate content, primarily lactose, contributes to energy provision and calcium absorption. Donkey milk is also distinguished by its rich vitamin profile, particularly vitamin C (about 4.75 times higher than cow milk), and essential minerals including calcium, phosphorus, and zinc. The biological activities of donkey milk extend to various applications in infant nutrition, particularly for children with cow milk protein allergies, potential medical treatments for infections and inflammatory conditions, and cosmetic formulations. Despite these promising attributes, the donkey milk industry faces challenges including low milk yield, lack of standardized production methods, and quality control measures. The sustainable development of the donkey milk industry requires comprehensive approaches to resource protection, technological innovation, brand building, and supportive policies to realize its full potential in contributing to human health and economic development.

Climate change, driven by rising atmospheric concentrations of greenhouse gases (GHGs) such as CO₂, poses the most pressing environmental challenges today. Soil carbon (C) sequestration emerges as a crucial strategy to mitigate this issue by capturing atmospheric CO₂ and storing it in soil organic carbon (SOC), thereby reducing GHG levels and enhancing soil health. Although soil is the largest terrestrial C sink, capable of storing between 1500–2400 petagrams (Pg) of C, the practical potential for SOC sequestration through regenerative practices is still widely debated. This review examines the biotic, abiotic, structural, physical, and chemical limitations that constrain soil C sequestration, along with the human dimensions that influence these processes. It explores the role of plant physiology, root architecture, microbial interactions, and environmental factors in determining the efficacy of SOC sequestration. Furthermore, it discusses the potential innovative strategies, including photosynthetic modifications, root system engineering, microbial bioengineering, and the application of advanced materials such as C-capturing minerals, poly-carboxylic compounds, and nanomaterials, to enhance C capture and storage in soils. By providing a comprehensive understanding of these factors, this review aims to inform future research and policy development, offering pathways to optimize soil C sequestration as a viable tool for climate change mitigation.

Mining activities in Pakistan’s mineral-rich provinces threaten freshwater security through groundwater depletion, contamination, and flood-induced pollution. This study develops an Inclusive Disaster Risk Reduction (IDRR) framework integrating governance, social, environmental, and technical (GSET) dimensions to holistically assess mining-induced water hazards across Balochistan, Khyber Pakhtunkhwa, and Punjab. Using GIS-based spatial risk mapping with multi-layer hydrological modeling, we combine computational analysis and participatory validation to identify vulnerability hotspots and prioritize high-risk mines. Community workshops involving women water collectors, indigenous leaders, and local experts enhanced map accuracy by translating indigenous knowledge into spatially referenced mitigation plans and integrating gender-sensitive metrics to address gendered water access disparities. Key findings reveal severe groundwater depletion, acid mine drainage, and gendered burdens near Saindak and Cherat mines. Multi-sectoral engagements secured corporate commitments for water stewardship and policy advances in inclusive governance. The framework employs four priority-ranked risk categories (Governance-Economic 15%, Social-Community 30%, Environmental 40%, Technical-Geological 15%) derived via local stakeholder collaboration, enabling context-specific interventions. Despite data limitations, the GIS-driven methodology provides a scalable model for regions facing socio-environmental vulnerabilities. The results demonstrate how community participation directly shaped village-level water management alongside GSET analysis to craft equitable risk reduction strategies. Spatially explicit risk maps guided infrastructure upgrades and zoning regulations, advancing SDG 6 and 13 progress in Pakistan. This work underscores the value of inclusive, weighted frameworks for sustainable mining–water nexus management in Pakistan and analogous contexts. Full article

Pineapple (Ananas comosus) is an important crop worldwide, due to its nutritional properties. It is well known as a rich source of vitamins (A, C, and D) and various minerals that are vital in human diets. The aim of this review was to explore the economic viability of organic fertilizers that improve growth, yield, and quality during pineapple production in Africa. This study was conducted through a comprehensive analysis of the literature from peer-reviewed journals. It was reviewed that organic fertilization is a general agricultural approach that prioritizes environmental sustainability, biodiversity, and soil health through the avoidance of chemicals, including inorganic fertilizers. It was also found that organic fertilizers can effectively improve growth performance, yield, and the quality of the pineapple fruit to levels comparable to those of the fruit grown using inorganic fertilizers. Subsistence and smallholder farmers have adopted organic fertilization more than commercial farmers. Various challenges, including high certification costs, limited market access, high operating costs, inadequate farmer training, and limited knowledge on producing fruit using organic fertilizers, have been reviewed. The potential for higher market prices for organically produced fruit was noted, together with the challenges. Despite higher market prices and environmental benefits from organic fertilization, the economic viability of organic fertilizers for pineapple production is constrained by other factors, such as pest management difficulties, as the policies of conservation agriculture limit the use of chemical pesticides or the introduction of alien species as biocontrol agents.

Seafood waste is often landfilled and/or discarded into water, raising microbiological pollution and environment policy concerns. Repurposing this low-cost biomass collected at point-source processing centers can help reduce greenhouse gas emissions and support industrial progress in developing economies. Safe alternative methods to utilize seafood waste were investigated. Hydrothermal carbonization-enriched shrimp shell waste was converted into higher-value products, such as sprayable fertilizer and dry biochar fertilizer pellets. Environment friendly sprayable fertilizer from shrimp and crab shell waste as an inexpensive carbon fixer is a potential solution. An average spray coverage area of 0.12 m² from only 300 mL of 1:10 shrimp shell waste to water mixture is reported. Characterization using N:P:K ratios from elemental analysis showed crustacean shell waste to comprise long-term organic carbon fixers in the soil with minor mineral enrichment, demonstrating potential for long-term soil care. Additionally, hydrothermally carbonized mineral rich shrimp shell and untreated crab shell waste were pelletized to test their friability and feasibility in transportation. Such a bio-investigation to promote economic goals for sustainability can improve biomass waste handling locally. Full article

For the European Union in the field of raw material policy, it is primarily important to ensure reliable, seamless, and unrestricted access to raw materials in all EU countries. An important aspect in assessing the European Union’s raw material policy is a detailed analysis of selected significant raw materials. This paper focuses on raw material policy within the European Union (EU). Specifically, it examines five types of raw materials: critical raw materials, metal ores, non-metallic minerals, fossil energy materials, and biomass. The research is oriented to analyzing the materials from the perspectives of consumption, mining, export, and import. The objective is to assess the European Union’s (EU) raw material policy by employing specific tools and statistical methodologies to analyze individual data. We aimed to assess the European Union (EU) raw material policy using selected statistical methods such as regression and correlation analysis, multivariate analysis, and pairwise correlation to reveal and describe the relationships between variables. Based on the examination of import and export data, it is evident that imports are on the rise while exports are declining. This trend underscores the EU’s continued reliance on raw materials sourced from other global regions. The results show that domestic production and consumption are sufficient; on the other hand, the EU remains dependent on imports of critical raw materials. The results are useful for the development of future EU raw material policy. Full article

Mineral elements are essential for human health. Our previous study identified distinct clusters of health-related mineral elements in surface soil among different regions and demonstrated an association between these clusters and health profiles in the USA. The present study further explores the relationship between these mineral clusters and mortality from detailed specific types of cancers and cardiovascular diseases by using county-level data from 3080 counties across the USA. Utilizing multivariate regression models with adjustment for socio-demographic and geographical factors, our analysis of county-level data revealed that residents in the regions of ‘infertile’ cluster have higher mortality rates for most types of cancers (18/29) and cardiovascular conditions (4/10) compared with people who live elsewhere. Notably, this relationship is pronounced for several specific leading causes of death such as tracheal, bronchus, lung cancer (regression coefficient (99.5% CIs), 6.29 (4.46, 8.13)), prostate cancer (1.06 (0.53, 1.6)), cerebrovascular disease (3.15 (1.74, 4.55)), and hypertensive heart disease (1.23 (0.23, 2.23)). Our findings highlight the critical role of soil minerals in human health and underscore the need for integrating geochemical data in public health strategies and environmental management policies.

The global shift toward green technologies presents a dual challenge: surging demand for clean technology products and an increasing reliance on critical raw materials (CRMs). While the existing literature has largely concentrated on economic, geopolitical, or general governance perspectives, scant attention has been devoted to the legal, institutional, and justice dimensions of mineral resource governance. This article addresses this gap by examining the European Union’s evolving policy framework—particularly the Critical Raw Materials (CRM) Act—and its implications for Romania’s national regulatory landscape. Employing a mixed-method approach that combines a systematic literature review and a SWOT analysis, this study assesses Romania’s capacity to align its mineral governance with the EU’s objectives for supply security, environmental sustainability, and strategic autonomy. Its findings underscore the urgent need for Romania to streamline its regulatory frameworks, enhance institutional coherence, clarify property rights, and reform licensing and fiscal regimes to attract investment and ensure legal predictability. Advancing green mining technologies, recycling initiatives, and sustainability-focused innovations is also vital for aligning national practices with the EU’s environmental and economic goals. By foregrounding issues of transparency, good governance, and procedural justice, this article offers new insights into how national and supranational governance structures intersect in the context of the green transition. This study provides valuable recommendations for policymakers, industry actors, and scholars seeking to strengthen Romania’s position within the EU’s broader resource security and sustainable development strategies.
