Land use sustainability (LUS) has exhibited profound impacts on addressing global change and achieving sustainable development. Although numerous policies have been implemented to improve LUS, their effectiveness remains unclear. This study builds an integrated assessment to model LUS dynamics in China for 2035 under nine scenarios, combining Shared Socio-economic Pathways (SSPs), Representative Concentration Pathways (RCPs), and three land use policy-oriented scenarios: Business As Usual (BAU), Biodiversity and Agricultural Adaptation (BAA), and Chinese Territorial Spatial Planning (TSP). Using the global change analysis model and future land use simulation model, we quantify changes and interactions among Ecological Sustainability (ES), Production Sustainability (PS), and Living Sustainability (LS). Under BAU, ES declines are predominant – with improvements observed in only 5 provinces under SSP126 and SSP245, and 3 provinces under SSP460 – while significant trade-offs emerge between ES-PS and PS-LS, with modest ES-LS synergy. In contrast, BAA outperforms enhancing average LUS, while TSP yields the most optimal outcomes. Specifically, under SSP126-TSP, up to 22 provinces show highest ES and LS, and PS peaks in 24 provinces. Meanwhile, Pearson correlation coefficient between ES-LS synergy reaches 0.46 under SSP126-TSP. Overall, TSP markedly reduces trade-offs and fosters synergies across all dimensions. These findings highlight TSP’s critical role in sustainable land use and provide actionable insights for policymaking to achieve sustainable development goals in China and globally.

Phosphorus (P) is a critical nutrient for food production and population growth, particularly in regions with malnutrition such as Africa. This study estimated P flows across 53 countries in Africa from 2000 to 2020, aiming to understand the historical impacts of P on the African food system. Africa is endowed with substantial P resources, having extracted 125 Mt of P from phosphate rocks between 2000 and 2020, with Morocco accounting for 64% of this total. Despite 79 Mt of P in Africa being exported in terms of either rocks or fertilizers, only 3% of P produced within Africa was traded between African countries during this period. Additionally, 12 Mt of P were utilized for agricultural production. Intensive agricultural practices and inadequate P chemical fertilizer inputs have exacerbated soil P depletion in agricultural land in some African countries, especially Ethiopia. Nearly 20% of the food P is imported from other continents, which indicates a supply-chain P trade tendency of exporting from Africa as low-value rocks and then importing as downstream high-value food. Scenario analyses for the year 2050 suggest that while P demand can be decreased 492 kt through a combination of reducing food loss fraction and improving diet management, only increasing fertilizer P input could eliminate the African future P demand. Therefore, this study highlights the need for closer cooperation among African countries to improve local use of P resources and eliminate hunger within the continent.

Chinese cities face escalating tensions between pollution mitigation and economic equity. Using an environmentally extended multi-regional input–output (EE-MRIO) model, we quantified the carbon and air pollutant footprints of 309 cities from 2012 to 2017 and applied structural decomposition analysis (SDA) to identify key emission drivers. The results indicate that inequality in air pollutant emissions, with a Gini coefficient of 0.31–0.53, is significantly higher than that of CO₂ (0.33–0.41). Developed cities generate 3.1 times more economic output per unit of CO₂ emissions than less developed cities, with the disparity widening over time. While intermediate input optimization contributed to a 1.94 Gt reduction in CO₂ emissions, its benefits were largely concentrated in developed regions and were accompanied by increased emissions of PM

, BC, OC, and CO. Although reductions in emission intensity played a crucial role in mitigating pollutants, they paradoxically contributed to CO₂ growth in energy-intensive cities. Additionally, population growth and per capita final demand were the primary drivers of emission increases, and population growth had a greater impact on developed regions. These findings underscore the need for regionally differentiated policies, including carbon quota reallocation, industrial transformation in energy-dependent cities, and the promotion of green industries in less developed areas, to achieve a balance between environmental sustainability and economic development.

The Yellow River Delta, characterized by intense land-sea interactions, has a highly sensitive and fragile environment. Livestock residue, transported through runoff and infiltration, exacerbates soil and water contamination, posing a threat to offshore waters. Thus, mitigating the environmental risks associated with livestock residue in the delta is urgent. This study integrated field measurements and model analysis to provide new insights into livestock residue pollution control. It examined discharge characteristics in soil and aquatic environments and assessed the spatial distribution of pollution potential. In the Yellow River Delta, total nitrogen and total phosphorus levels in livestock residue exceeded the Ministry of Ecology and Environment’s limits by 3–6 times and 7.2 times, respectively. Large-scale breeding primarily reduced pollutant loads by increasing flushing. Shortening the distance between farms and rivers, along with adopting wet cleaning methods, mitigated nitrogen, phosphorus, and organic matter pollution risks. Compared to anaerobic digestion, aerobic composting reduced pollutant levels in manure but increased organic matter in slurry. Soil pollution was severe near farms, with total nitrogen and organic matter concentrations 2.0 and 2.1 times higher than those along the vertical transect from farms to rivers, while water pollution was relatively benign. High-risk non-point source pollution areas were concentrated in the northwest and south of the Yellow River Delta. Even low-risk waterways, such as the Yellow River and Xianxian Ditch, posed potential threats to the Bohai Sea. Optimizing breeding scale, flushing intensity, manure cleaning and treatment methods, and farm-river distances can effectively reduce pollution risks.

Since China’s import ban, there has been a stimulated global interest in the international trade of plastic wastes, but with a limited focus on the impact of such downstream events on the trade of primary plastics. Thus, this study focuses on analyzing the global trade of primary plastics from 1988 to 2022 to understand the effects of different events on the trade and offer policy implications. Specifically, we reconstruct relevant trade data from the UN Comtrade database using a rigorous method to handle data reporting issues in the database. The results show that the cumulative global trade of primary plastics reached 3,411 megatonnes over the past 35 years. The global trade boosted after 2017 as a result of China’s increasing import to mitigate the raw material shortages brought by its import ban of plastic wastes. A first negative growth of the global primary plastic trade in a decade showed up in 2022 due to China’s shrinking demand. This study also offers a detailed analysis about the current policy landscape, urgently calling for a well-designed policy framework aiming at sustainability throughout the entire plastic life cycle.

Since 2007, cities have accommodated more than half of the global population. Their growth has led to significant environmental modifications and at least some degradation of the natural environment, with significant consumption of imported resources, waste generation and pollutant emissions. This on the one hand leads to a special importance of cities for planetary health, and on the other hand underlines the necessity of integrated approaches in environmental resources management for improving urban planetary health. However, the role of integrative approaches, such as the Resource Nexus, in urban planetary health remains insufficiently explored. This study addresses this gap by conducting a semi-systematic literature review, following the PRISMA guidelines to select and document the current state of knowledge on urban planetary health and the role of the Resource Nexus approach for sustainability transformations in this context. Based on 57 papers, a qualitative text analysis was conducted through the lens of the Resource Nexus framework. It was found that all key environmental resources are covered regarding their role for urban planetary health, with climate, food, biota, land, and water identified as the most critical elements for enhancing planetary health. Moreover, the analysed literature shows that despite the many challenges, urban areas offer a multitude of opportunities for societal, political, and economic interventions that can benefit environmental and human health. Maximizing synergies and minimizing trade-offs requires addressing both challenges and opportunities. This often involves making multiple changes at both the urban societal and governance levels. These changes create a systemic shift, moving away from prioritizing economic prosperity and towards a focus on planetary health.

Global food trade has been growing and diverse with environmental burden shifting across the trade bilateral partners. However, the temporal evolution of the environmental impacts and resources degradations embedded in food trade remains unclear for the recent decades. This study analyzes China’s food supply and trade relationships of 71 food items with 174 countries and territories from 2010 to 2020, examining the associated water, land, carbon footprint (WF, LF and CF) based on the bottom-up method, as well as the corresponding virtual water, land, carbon flows and resources saving. Results show that WF and LF of Chinese food consumption increased while CF decreased over the period. National net virtual water, land and carbon imports more than doubled, mainly due to the import of legumes and nuts from Latin America. Trade conserved 56.6 Mha/yr of land but consumed 30 Gm³/yr of water and raised net carbon emissions by 56 Mt/yr in 2020. This analysis shows a crucial view on the non-negligible role of a certain country’s food trade network changes on global environmental degradations though worldwide food productivity improvements.

Effective management of terrestrial ecosystems is crucial for mitigating climate change, especially in regions like Guizhou Province, where significant carbon sequestration potential is challenged by urbanization and ecological initiatives. This study simulates the spatiotemporal dynamics of carbon storage in Guizhou under multiple land use and land cover (LULC) scenarios and explores their ecological and economic impacts. Specifically, LULC and ecosystem service data were applied to assess carbon storage and habitat quality from 1990 to 2020. LULC projections from 2030 to 2060, incorporating habitat quality constraints, were generated to assess carbon storage and its economic value. The results show that Guizhou’s carbon storage increased from 3423.13 Tg to 3475.42 Tg, with forest restoration increasing it by 301.62 Tg and agricultural expansion reducing it by 218.63 Tg. Projections indicate continued growth under the current trend, with 125.19 Tg of carbon sequestration valued at 11.29 billion Chinese Yuan by 2060. Ecological initiatives could accelerate these benefits, while urban expansion may limit them. Carbon storage in different sequences of development scenarios was similar, suggesting that later development strategies can partially offset earlier differences resulting from varying priorities. Nevertheless, it remains essential to consider the sequence effects on other ecosystem services and socioeconomic factors. These findings highlight the importance of ecological engineering and reveal the flexibility in balancing ecological goals with urban development, providing guidance for long-term integrated planning to achieve sustainable development. This study provides a methodological basis for carbon storage research, supporting regional land management practices in the context of carbon neutrality.

Projections indicate continued growth under the current trend, with 125.19 Tg of carbon sequestration valued at 11.29 billion Chinese Yuan by 2060. Ecological initiatives could accelerate these benefits, while urban expansion may limit them. Carbon storage in different sequences of development scenarios was similar, suggesting that later development strategies can partially offset earlier differences resulting from varying priorities. Nevertheless, it remains essential to consider the sequence effects on other ecosystem services and socioeconomic factors. These findings highlight the importance of ecological engineering and reveal the flexibility in balancing ecological goals with urban development, providing guidance for long-term integrated planning to achieve sustainable development. This study provides a methodological basis for carbon storage research, supporting regional land management practices in the context of carbon neutrality.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"21 ","pages":"Article 100223"},"PeriodicalIF":12.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Globally, vegetation establishment is an important approach for controlling soil erosion, which induces land degradation. However, the understanding of the effects of tree species diversity on soil erodibility across spatial scales remains incomplete. This study employed the Universal Soil Loss Equation model to quantify soil erodibility and aligned it with tree species diversity data obtained from the Global Forest Biodiversity Initiative database. Our findings revealed a global decrease in soil erodibility with increases in tree species diversity, though this relationship varies among biomes and ecoregions. Specifically, soil erodibility decreased with increasing tree species diversity in 6 of the 11 biomes and 54.90% of the ecoregions analyzed. Comprehensive analyses revealed that increased productivity, NDVI, and basal area mediated this reduction in erodibility across both groups. In ecoregions where tree species diversity was negatively correlated with soil erodibility, lower precipitation during the driest month and quarter, higher precipitation seasonality, lower silt content, and higher elevation were observed compared with those of the ecoregions with positive correlations between tree species diversity and soil erodibility. Among ecoregions characterized by clay content > 18.3% and silt content < 40%, 79.55% exhibited a reduction in soil erodibility as tree species diversity increased. These findings highlight the inherent spatial variability and mechanistic complexity of biodiversity-soil erodibility relationships, underscoring the need for targeted, soil-specific restoration strategies.

Pedestrians are particularly vulnerable to air pollution due to their proximity to pollutant sources and elevated respiratory rates during physical activity, amplifying cumulative health risks. However, existing studies focus on concentration- or residence-based exposure assessment, overlooking the dynamic interaction between pollution patterns and pedestrian activity. This study therefore introduces a novel methodological framework to assess pedestrian-specific exposure to PM2.5 in diverse urban environments. Applied to New York City, the framework leverages graph-based machine learning to predict street-level PM2.5 concentrations from vehicle-sensed pollution data, while estimating high-resolution pedestrian volume derived from street view imagery and ground-truth count data. The results reveal significant divergences between traditional exposure assessments and pedestrian-specific exposure patterns, uncovering previously overlooked high-risk zones. High-exposure hotspots are not limited to areas with elevated pollution levels but also include locations where moderate pollution coincides with high pedestrian activity. This study also explores the spatial relationship between exposure patterns and urban vegetation coverage, providing actionable insights for targeted interventions. By bridging the gap between pollution dynamics and pedestrian activity, this research provides urban planners and policymakers with new insights for developing pedestrian-centered air quality management strategies, contributing to healthier and more sustainable urban environments.
