With resource extraction and transformational development, the hindering effect of land use spatial conflict (LUSC) on mining city development is significant, highlighting the importance of exploring the dynamic mechanism of LUSC for sustainable development. This study integrates the multidimensional attributes of LUSC, constructs a LUSC assessment framework based on “element- pattern-effect”, and proposes theoretical hypotheses on the dynamic mechanism of LUSC. Taking Xintai City, a typical mining city in China, as an example, we analyzed the characteristics of LUSC evolution from 2000 to 2020 and explored the impact mechanism of LUSC by using the SEM model. Results show that the high risk of LUSC in mining cities is clustered in mining-city intertwined zones, and the growth rate of LUSC risk increases significantly with the transition period. The dynamic mechanisms of LUSC in mining cities are mutually driven by natural and anthropogenic factors and are dominated by anthropogenic factors. On the impact pathway, ecological environment, socio-economic environment, and resource extraction have stable and significant direct effects on LUSC. With improvements in technology and policy, the constraints on land use imposed by the natural environment have gradually decreased, and the impacts on LUSC are mostly indirect. This study proposes a research framework for the dynamic mechanism of LUSC in mining cities to provide theoretical guidance and suggestions for promoting urban transformation and development.

The intensifying demand for energy transition minerals (ETMs) has triggered global concern over water-related issues in mining regions. However, localized and generalizable metrics are lacking to help companies and governments manage social licenses to operate (SLO). In this study, we propose an analytical method that combines digital media data from the Global Database of Events, Language, and Tone (GDELT) with high-resolution mining data to analyze social awareness. LightGBM with Shapley additive explanations models are introduced to uncover key factors influencing public sentiment. This approach was applied to analyze media attention and public sentiment on five categories of water issues across 12 mineral types and 511 mines from 2016 to 2023. Our findings show a 40% increase in water-related events linked to ETM mining since 2020. Regions such as East and Southeast Asia, and Central and South America exhibit rising but negative sentiment, while public discontent in Southern Africa remains consistently high. Cobalt, platinum, and vanadium have the most negative sentiment, particularly concerning water quality and pollution. Manganese shows the most negative sentiment due to concerns over drought and desertification. Model results indicate that the Goldstein scale of events, which reflects the magnitude of cooperation or conflict, was the most influential factor in shaping public sentiment. Precipitation has a significant positive impact on sentiment in drought- and flood-related events, while higher runoff improved sentiment in drought events but negatively affected flood- and water quality-related events. Socio-economic factors, such as educational expenditure and unemployment rates, also demonstrated varied effects across categories. Finally, this study introduces the water sentiment index (WSI) as a proxy for water-related SLO concerns, offering a new tool to track social awareness in ETM regions and providing actionable insights for policymakers and stakeholders to mitigate social risks and ensure sustainable mining practices.

Due to the advantages of high energy density, high conversion efficiency, and rapid response speed associated with power lithium batteries, there has been a significant expansion in their use. However, industry forecasts indicate that if large quantities of waste lithium-ion batteries are not managed properly, it could lead to serious environmental pollution issues as these batteries reach the end of their life cycle. Therefore, developing highly efficient and environmentally friendly recycling technologies is urgently needed. This paper proposes a green and efficient selective lithium extraction process integrating leaching technology with electrochemical methods. This approach enables the separation of Li and FePO₄ within an electrolyte through electric field assistance while effectively minimizing waste liquid generation. The effects of various factors on Li and Fe’s leaching rates were investigated using orthogonal and single factor experiments. Under optimal conditions, the leaching rate of Li reached 98.85%, while that for Fe was only 0.22%, resulting in a selectivity ratio (Li/Fe) of 99.78%, which demonstrates successful selective extraction of lithium. Furthermore, we assessed the feasibility of this experiment through potentiometric-pH diagrams. We elucidated its mechanism using XPS, XRD, and SEM. Unlike conventional destructive leaching methods, the Li extraction process facilitated by the electric-field-induced assistance resembles the charging process of LiFePO₄ batteries. Ultimately, Li was recovered as Li₂CO₃, while Fe and P present in the slag were subsequently retrieved as FePO₄ with battery-grade purity through a hydrothermal method. This study presents an environmentally sustainable and economically viable approach for recovering spent LiFePO₄ batteries.

Refrigeration has significantly enhanced human well-being but comes with notable environmental impacts, particularly due to ozone-depleting substances and hydrofluorocarbons with high global warming potential. Solar Thermal Adsorption Refrigeration (STAR) has emerged as a promising alternative, especially in rural and off-grid regions where conventional refrigeration systems face energy limitations. This paper provides a comprehensive review of recent advancements in adsorption refrigeration technologies, including novel adsorbents like activated carbon–ethanol, metal–organic frameworks (MOFs), and composite materials designed to overcome critical challenges in heat and mass transfer. A particular emphasis is placed on the size limitations of adsorbers and the thermal efficiency of working pairs. Additionally, we critically analyze the life cycle environmental impacts of adsorption refrigeration systems, evaluating their sustainability compared to conventional vapor compression technologies. Unlike previous reviews, this paper integrates both technological developments and life cycle assessments, offering a unique perspective on STAR’s viability for sustainable refrigeration solutions. Finally, we present two novel bench-scale STAR systems, compare their environmental performance to traditional systems, and highlight key design improvements that address scalability challenges.

The effective management of nitrogen pollution in urban environments presents unique challenges due to the cross-sectoral and cross-media characteristics of nitrogen migration and transformation. Using Macao as a case study, this research dynamically simulates urban nitrogen metabolism from 2000 to 2021 to explore its trends, drivers, and environmental implications. Through Element Flow Analysis, a cross-sectoral and cross-media nitrogen metabolism model was developed to identify critical pathways and key sectors in nitrogen dynamics. Results reveal a significant increase in nitrogen input, output, and environmental load during the study period. The food sector dominated urban nitrogen metabolism, contributing 46.35% of total nitrogen inputs, with an average annual input exceeding 3000 tons. Soil and water bodies experienced cumulative N inputs of approximately 5700 tons and 28000 tons, respectively, while atmospheric nitrogen flows decreased by 10.49%. The study identified insufficient wastewater treatment capacity and pipeline leakage as primary contributors to nitrogen emissions, alongside significant deficiencies in organic waste recovery. Driving force analysis highlights population growth and shifts as dominant factors influencing nitrogen metabolism. Ecological Network Analysis further reveals complex interactions within the nitrogen cycle, emphasizing the need for integrated urban management strategies. This study underscores the urgency of coordinated cross-sectoral and cross-media approaches to mitigate urban nitrogen pollution, providing actionable insights for sustainable urban resource management and policy development.

Climate change and sustainability linkages provide opportunities to develop and implement synergistic strategies for climate actions and achieve Sustainable Development Goals (SDGs). Thus, we synthesize the coverage of SDGs in the IPCC’s fifth and sixth assessment reports at a target level. Based on this reflection, we propose the seventh assessment cycle of the IPCC to cover SDGs holistically, using a systematic approach, breaking the Working Group silos, and contributing to the post-2030 agenda.

The neglected disproportionate contributions of active fires in greenhouse gas emissions globally

The steeply rising greenhouse gas (GHG) emissions poses significant safety hazards to human society and global change, which was generally sourced from fires as well as fossil and bio fuels combustion. Since 2000, global carbon dioxide (CO₂) emissions from active fires have been approximately 25% of those from fossil fuels and land use change. Due to the complicated mechanisms of interactions between active fires and GHG emissions, the size, distribution, and changes of GHG emissions from active fires contributions exist wide differences. The contributions of active fires to GHG emissions and their discrepancies as well as driving mechanisms at the global scale remain poorly understood systematically. Here, we combine GHG emission, active fires, land cover, temperature, and population products (2003–2021) to quantificat the spatio-temporal features of fires-induced GHG emissions and possible drivers. Although the proportions of GHG emissions from active fires showed a descending tendency with fluctuation, the annually totality almost kept increasing since 2003. Among total 9.71 × 10⁵ million tons GHG emissions, active fires released approximately 20% (1.85 × 10⁵ million tons), and shows significant regional variability. Land cover, temperature, and population jointly regulated global disproportionate contributions of active fires in GHG emissions. Most areas, where GHG emissions from active fires obviously exceeded that from fossil and bio fuels combustion, were sparsely populated. Over 43% of GHG emission contributions from active fires were counted in Brazil, the Democratic Republic of Congo, Kazakhstan, Mainland of Southeast Asia, and Australia. Our findings emphasize the crucial contribution of active fires to global carbon emissions, particularly CO₂ emissions. Future efforts on global warming alleviation, carbon neutrality, GHG budgets, and sustainable development should take the impact of fire emissions into account.

The environmental impacts of consumption behavior are not evenly distributed across different groups. Here, we develop an analytical framework by integrating input–output analysis, Lorenz curves drawing, spatial disequilibrium decomposition, and geographic transfer identification, enabling quantify the disparities in environmental responsibilities between urban and rural residents’ consumption behaviors. This framework is applied to China, the most populous country globally, for case study integrating three key dimensions: water consumption, fossil energy usage, and carbon emissions. The water resource, energy, and climate responsibilities associated with the urban residents’ consumption behavior were 2.68–2.92, 3.08–3.40, and 3.12–3.46 times that of rural residents in the three investigable years. Rural per capita consumption environmental footprints were less than half of urban residents. Provinces representing 20% of China’s urban and rural population generate 27%–36% of the country’s blue water, fossil energy, and carbon footprints. The spatial disequilibrium of residents’ consumption environmental responsibilities is significant but shows a weakening trend. Coastal developed regions tend to be net inflow areas of embodied water, fossil energy, and carbon dioxide, transferring embodied environmental pressures to inland regions. A progressive consumption footprint tax policy that considers contribution to economic growth is a potential approach for redistributing the consumption responsibilities between urban and rural residents.

Electron transport derived from microbial self-generation or consumption is a fundamental oxidation–reduction force for matter transformation and energy communication. The most abundant quantity and species of microorganisms are present in soil, and the ecological functions of microbial electron transfer coupled with soil evolution processes as well as the main element cycles have received increasing attention. Developing soil bioelectrochemical system (BES) is a convenient and efficient approach for the sustainable management of soil environment. In this review, the effects of element transformations, including carbon, nitrogen, iron, and sulfur, were examined, with a primary focus on the efficiency of a soil BES in monitoring biocurrent conduction. Moreover, the factors affecting the soil BES were summarized from the perspective of physical, chemical and biological processes. The ecological functions of soil biocurrent conduction for removing pollutants, amending alkaline acidification, desalination, detoxifying heavy metals, reducing methane emissions, and increasing soil fertility were subsequently reviewed. Finally, knowledge gaps and perspectives involving the identification of electroactive microorganisms, electron transport pathways, the regulation of element cycles, and key applications of soil BES were proposed. Overall, soil BES would provide versatile support to improve the environmental control approach and agricultural sustainability.

Studying the water-emissions-food nexus (WEF Nexus) is crucial for the sustainability of agricultural economic systems. The multi-regional input–output (MRIO) model provides insights for water-emissions-food integrated collaborative management. This study develops a detailed agriculture-oriented MRIO model based on the RAS method, which disaggregates the agricultural sector into 12 sub-sectors. The water consumption and greenhouse gas (GHG) emissions are allocated to the entire supply chain to identify the key regions and routes of the WEF Nexus in China for 2017. Then the environmental output level of the agricultural sector and its sub-sectors is analyzed using productivity indicators. Results demonstrate that the agricultural sector exhibits a strongly connected WEF Nexus (coefficient of 0.87), particularly in Coastal and Southwest regions. The synergistic relationship between water and emissions suggests significant opportunities for implementing integrated management strategies. 73.3% of virtual water and 71.7% of embodied emissions are concentrated in downstream non-agricultural sectors of supply chains, highlighting the substantial impact of trade transmission on the environment. The water and emissions productivity in the agricultural sector are spatially aligned except in the Central and Southwest regions. As significant agricultural output regions, Northeast and Central regions have lower water or emissions productivity, making sustainable agricultural development more challenging. Therefore, practical measures should focus on promoting technological innovation and its adoption to enhance water use efficiency and reduce GHG emissions in agricultural production.
