This study employs a novel biodiversity risk measure, developed through textual analysis, to examine how biodiversity risk affects socially responsible investment (SRI) and commodity markets. Biodiversity-related financial risks, arising from ecosystem degradation, represent an emerging and underexplored dimension of market risk, particularly for investors seeking sustainability-aligned portfolios. Our analysis reveals that both SRI equity and commodity indices consistently exhibit negative time-varying correlations with biodiversity risk, with correlations as low as -0.62 for the FTSE4Good US 100 and -0.53 for the FTSE4Good Global 100. Similarly, commodities like silver, gold, crude oil, and wheat also show negative correlations with biodiversity risk. These findings indicate that neither asset class serves as a reliable hedge against biodiversity-related shocks. Furthermore, biodiversity risk has a significant long-term spillover effect on SRI equity and commodity market returns. As biodiversity risk increases, it strengthens the connectedness between these markets, thereby amplifying the transmission of risk across them. These findings highlight the need for new risk management strategies and regulatory frameworks that account for biodiversity risk, opening new research pathways in finance and environmental sustainability.

Desert ecosystems, as an important part of terrestrial ecosystems, are considered potential hidden carbon sinks in the global carbon cycle. The Gurbantunggut Desert, as China's largest fixed/semi-fixed desert, has received little research on its role in the global carbon cycle and future trends. This study utilizes continuous observational data from the Gurbantunggut Desert from 2018 to 2022 and integrates CMIP6 global climate model scenario data to study the evolution of carbon balance in the desert ecosystem, carbon source/sink functions, and future trends. The result showed that: 1) The CO2 flux in the Gurbantunggut Desert shows Carbon sink during the day and carbon source at night, with an annual cumulative carbon sink duration of over 240 days.2)From 2018 to 2020, the desert ecosystem of the Gurbantunggut Desert functioned as a net CO2 sink.3) Desert ecosystems were subjected to concurrent influences from multiple environmental factors across varying time scales, with photosynthetically active radiation, air temperature, and soil temperature identified as the most influential factors affecting CO2 flux in the Gurbantunggut Desert. 4) The climate of the Gurbantunggut Desert is projected to exhibit a trend of warming and increased humidity in the future. Against the backdrop of future warming and humidification, the Gurbantunggut desert ecosystem is anticipated to exhibit a pronounced carbon sink characteristic.

Balancing the forest protection with local economic development is a pressing challenge and a key focus of current environmental policies. Ecological compensation programs (ECPs) are often employed in natural-resource dependent communities to address this dilemma. However, the impacts of ECP on local livelihoods remain controversial, and the mechanisms driving these outcomes are not fully understood. We investigate the impacts of an ECP on the livelihoods of rural residents, drawing on survey data collected from forest communities in Zhejiang, China. Using the propensity score matching (PSM) method to address potential self-selection bias, our findings reveal that ECP has significant and positive impacts on local livelihoods. This improvement is primarily attributed to increased income from forestry and gardening, alongside greater livelihood diversification. While non-agricultural livelihoods are increasingly important, agriculture remains a vital source of household's income. Additionally, the benefits of ECP are disproportionately enjoyed by wealthier and younger residents as well as those who are not left behind, suggesting a potential exacerbation of inequality among household groups. In light of these findings, we recommend implementing tailored financial assistance, enhancing training opportunities, and creating specialized employment roles for vulnerable groups, thereby supporting their livelihood transitions, advancing social equality and fostering the sustainable conservation of forest ecosystems.

Strengthening the rule of law is the cornerstone of ecological environmental protection. In the context of sustainable development, countries generally recognize the key role of the legal system in the protection of the ecological environment. Based on the perspectives of management, economics, and jurisprudence, this paper explores the impact and internal mechanism of the ecological legal system represented by the environmental protection court on the green innovation of enterprises. The study revealed that the ecological rule of law elevates enterprises’ green innovation. The cost of environmental investment and enterprise strategy adjustment both reinforce the impact of the ecological rule of law on enterprises' green innovation. In the external environment of enterprises, the ecological rule of law on enterprises' green innovation has a more pronounced influence when Officials' appraisal pressure is high, and both the public and the government attach great importance to the environment. Within the internal environment of the enterprise, the ecological rule of law exerts a weaker force on the green innovation of the enterprise when the executives possess a low level of education, exhibits weak environmental awareness, and has a low shareholding ratio. The outcomes of this study might offer valuable insights for policymakers and enterprise managers in implementing environmental policies and in planning long-term green innovation for enterprises. Contribute to the strengthening of the legal system for ecological environmental protection in all countries.

Many refugee camps exist for decades but associated infrastructure needs are only planned for the very short term, including provision of power. This study advocates a shift in approach to sustainable electrification of essential services in refugee camps for lighting, refrigeration, health, water, education, alongside camp operations. Qualitative and quantitative surveys were conducted in refugee camps in Uganda and Bangladesh which assessed the electrical supply needs across such categories. A range of solar photovoltaic (PV) power systems (Solar Home Systems, AC/DC mini grids) and their emission mitigation potential were modelled based on survey data. Proposed designs were compared with presently-used diesel systems in terms of applicability, environmental impact and economics. Results indicate significant cost savings are achievable through the PV systems deployment for different areas in two major refugee camps. Estimated savings range from USD31,000–140,000 and USD166,000–653,000 for five-year and twenty-year project lifetimes respectively. These savings apply to sub-areas of much larger camps, with potential savings increasing substantially if scaled to the whole camp. Results indicate that PV-battery systems were more cost-effective than diesel, even for five-year projects, with investments recoverable in second year of operation. Furthermore, replacing the existing 50 kW diesel generator in Bidi-bidi camp with a 40kWp PV-battery system would result in a reduction of 2.4 MtCO2e over a 20-year project lifetime. Adopting presented approaches will enhance humanitarian service provisions, reducing both cost and emissions. These findings are applicable to many refugee camps in Africa and Asia that have similar solar resource and lack of grid access.

Urban environments are usually polluted by anthropogenic activities like traffic, a major source of potentially toxic elements (PTEs), and ornamental plant species may reduce contamination by trapping traffic-related air pollutants in their leaves. The purpose of this study was tested the trapping pollutant capacity of four species commonly used in green areas of Seville city (SW Spain) to better choose species in urban green planning. Composition of particulate matter (PM) obtained from foliar surfaces (sPM) and wax-included (wPM) was determined by EDX-SEM analysis in samples from different city locations. Concentration of different PTEs (Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn), by microwave induced-plasma optical emission spectroscopy (MP-AES) were also analyzed in unwashed leaves of one of the selected species (Citrus aurantium) since it is the most cultivated species in Seville. Results showed that Nerium oleander was the plant species which trapped best superficial total and coarse PM. This capacity was enhanced by the presence of a waxy-cuticle and by cuticle thickness but not by leaf hairs. The only species unable to trap fine particles was Bougainvillea glabra. The most representative sPM on leaf surfaces from all species was the largest fraction (59–75%), followed by coarse (25–37%) and fine fractions (2.2–4.4%). In the wax PM, 48% of coarse particles were found in Citrus aurantium. Particulate matter deposited on surface foliage in general did not vary seasonally, while the large fraction of wPM in summer was significantly higher than in winter. The seasonal differences also existed in the level of PTE (Cd, Fe, Ni and V) in leaves. This work indicates that the leaf traits should be taken into account to evaluate the pollutants caption capacity, especially when planning of recreational green urban areas. Particulate matter composition was different according to the pollution sources and mostly contained Al, C, Ca, Fe, K, and Mg, but potentially toxic elements such as Si, As, Cr, Cu and Zn just accounted for 0.11–1.95% of the total elemental content.

The Eastern Boundary Upwelling Systems (EBUS) sustains some of the most productive marine systems on Earth. Within each of these systems, the upwelling process exhibits spatial and temporal variation resulting in marked differences in upwelling intensity and seasonality along extensive coastlines. The study of this variation is well needed, given the magnitude of the services provided by upwelling, and the impending impacts of global warming on EBUS. The critical link between the physical variability associated with upwelling intensity and its consequences on socio-ecological variables remain severely understudied. This study aimed to address such a gap by exploring the influence of coastal upwelling intensity on socio-ecological attributes of co-management units named Marine Exploitation Areas for Benthic Resources (MEABRs), along one the most productive ecosystems of the world: The southern Humboldt Current system. We evaluated the non-linear influence of upwelling on 1) the harvest of economically important resources, 2) the number of exploited species, 3) number and gender distribution of fishers involved, and 4) fishery activities. Our data indicated that on the one hand the annual harvest of commercial species, and all the exploited resources combined, were consistently higher in MEABRs associated with intermediate to high upwelling intensities. On the other hand, the harvest of kelp, the number of species harvested, and the number of fishers per MEABR increased towards low upwelling intensities, showing signals of fishery diversification. Interestingly, representation of female fishers increased towards high upwelling intensities, suggesting that multiple factors account for the variation in this, and other socio-ecological variables examined. Our study provides first-hand information about harvest levels and the allocation of fishery activities and gender distribution when MEABRs associated with different upwelling intensities are compared. Such information will assist in the identification of ecological and social vulnerabilities in a global warming scenario.

Waste pile substrates from Fe mining may carry potentially toxic elements (PTE). Rehabilitation efforts must maintain soil vegetation cover effectively, avoiding the dispersion of particulate matter and reducing the risk to the environment and human health. Therefore, this study aims to evaluate the pseudo-total and extractable contents, perform chemical fractionation, and assess the bioaccessibility and risk of PTE in waste piles of Fe mining in the Eastern Amazon. Soils were sampled from waste piles in different stages of environmental rehabilitation and from non-rehabilitated and native forest areas. The waste materials exhibit mean pseudo-total concentrations of Zn, Ni, Cr, and Cu that exceed the Brazilian soil quality threshold. However, they do not surpass reference values for human health safety. In addition, these elements are predominantly associated with the residual fraction, suggesting low availability. Among the 11 PTE evaluated, only Al, Cu, Fe, Mn, and Zn presented concentrations that were bioaccessible to the gastrointestinal tract. At the same time, Al, Fe, and Mn showed lung bioaccessibility. Soil properties limiting PTE extractability and bioaccessibility include pH and base saturation. Considering only elements above threshold levels, no environmental risk was observed, and the human health risk was considered insignificant for adult oral and inhalation exposure routes. Finally, the results show that high pseudo-total PTE contents in the analyzed Fe waste piles do not necessarily indicate high risks. However, substrate properties should be monitored over time to better understand their potential impacts and the main factors influencing their bioavailability.

Soil properties limiting PTE extractability and bioaccessibility include pH and base saturation. Considering only elements above threshold levels, no environmental risk was observed, and the human health risk was considered insignificant for adult oral and inhalation exposure routes. Finally, the results show that high pseudo-total PTE contents in the analyzed Fe waste piles do not necessarily indicate high risks. However, substrate properties should be monitored over time to better understand their potential impacts and the main factors influencing their bioavailability.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"374 ","pages":"Article 124059"},"PeriodicalIF":8.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142969149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As global phosphorus (P) stores rapidly decline, P fed algal blooms continue to threaten critical freshwater resources across the globe. In the Midwestern United States (US), particularly the Corn Belt, biorefineries could play a key role in addressing this issue. By recovering P from the byproducts of ethanol production these facilities could reduce the P content of distillers grain feed, thereby reducing P excreted in manures. This process could potentially divert P away from concentrated animal feeding operations (CAFOs) and toward renewable P (rP) fertilizer production utilizing the recovered P. To foster the inclusion of P recovery incentives in state nutrient reduction strategies, this study elucidates the cascading benefits of rP recovery from corn biorefineries in watersheds across six Upper Midwestern states. Incentivizing P recovery in watersheds that contain both biorefineries and CAFOs could foster the production of 107,500 metric tons (MT) rP fertilizer while diverting 26,800 MT P from CAFO wastes each year, nearly double the estimated P reduction potential for municipal wastewater in the analysis region. These estimates can inform nutrient reduction analysts and policymakers in determining P load reduction potential. To further guide incentive strategies, four priority watersheds are highlighted to illustrate P reduction and circularity typologies across the region.

Through a natural experiment setting in Hong Kong, this study examines the effects of financial incentives and nudges on consumer choices among three types of coffee cups: bring-your-own-cup (BYOC), shop-provided reusable cups, and disposable cups. Our dataset comprises 223 structured observations of coffee shops with 522 data points. The financial incentive—a direct price instrument set as a discount—is offered exclusively to customers who bring their own cups, while shop-provided (reusable) cups are not eligible. The results indicate that a financial incentive is not associated with a positive change in the behavior of the rewarded consumers: In this study, the discount does not significantly encourage consumers to bring their own cups. However, we find negative effects related to the choice of cup by consumers not rewarded by the incentive: A negative spillover effect emerges: consumers who have not brought their cups and thus who do not qualify for the discount are more likely to choose disposable cups. These findings highlight the limited effectiveness of financial incentives and nudges in reducing disposable cup usage and suggest the need for broader strategies to encourage sustainable consumption.
