This study analyzed LDN dynamics in Alawuha Watershed, Ethiopia, using remote sensing data of these indicators within Google Earth Engine (GEE) platform to identify areas requiring intervention. The study used Landsat 5 TM and 8 OLI imagery (2000–2023) for land use/land cover (LULC) change analysis with the Random Forest algorithm, MODIS Net primary productivity (NPP) data (2001–2023) for land productivity, and gridded SOC data to map SOC distribution. The spatial distribution of NPP trends was analyzed using the Theil-Sen slope estimator in GEE, and the modified Mann-Kendall (MK) trend test in RStudio was applied to analyze mean annual NPP trends. The \"one out, all out\" principle was used to evaluate the overall LDN status. Results revealed an increase in forest cover (+1.95 % annually) and built-up areas (+11.77 % annually) from 2000 to 2023, while farmland declined at an annual rate of −1.23 %, mainly due to urbanization. The spatial distribution of the NPP trends showed productivity gains in the western and southern regions (+35.85 gC/m²/year) but declines in the northeastern region (−10.99 gC/m²/year) and lower SOC, signaling localized degradation. The MK test confirmed a significant increase in mean annual NPP (tau = 0.3913, <em>p</em> = 0.00078) at (α=0.05), with a Sen’s slope of 7.51 gC/m²/year, showing overall productivity improvement. These findings support LDN targets and provide insights for sustainable land management and restoration policies.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"20 ","pages":"Article 101202"},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223341","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}

This study explores the potential of trout skins as a raw material to produce ecological leather and evaluates the biodegradability of the co-digestion of its effluents with the byproducts of the same fish. The biodegradability of the three substrates S1, S2 and S3 was 67.54 %, 41.95 % and 37.69 % respectively, while the experimental methanogenic potential was 318 Nml/g VS, 249 Nml/g VS and 217 Nml/gVS respectively. Four kinetic models were used to calculate the theoretical methanogenic potential of the three substrates: Logistic function, Modified Gompertz, Transference function and First order. The methane yield nearest to the experimental findings is that predicted by Logistic function, for S1 the yield was 314.92 Nml/g VS with a percentage error equal to 1.03 %, for S2 the yield was 249.38 Nml/g VS ( % error = 0.16 %), and for S3 the yield was 218.57 Nml/g VS ( % error = 0.75 %). Also, the results predicted by the Modified Gompertz model were close to experimental results. This confirms that the best models for estimating the methane yield from the co-digestion of trout byproducts and tannery effluent are the Modified Gompertz and Logistic function models.

The transition was enabled through the integration of real-time hydroclimatic monitoring, development of tailored rainfall and river level indicators, and collaborative governance involving academia, communities and local authorities. Key indicators such as A25, A10_min, P10Level, and i_med have enhanced predictive capacity, though limited historical event data constrain full validation and efficiency assessment. Lessons learned emphasize the importance of adapting international alert protocols to local dynamics, improving real-time data coverage, and strengthening community participation. The study also highlights institutional and governance challenges, including short lead times, limited forecasting tools, and the absence of comprehensive disaster databases.

This study evaluates the effectiveness and efficiency of CR quantification under the Carbon Removals and Carbon Farming (CRCF) Regulation, using Baden-Württemberg (Germany) as a case study. We designed a hypothetical agroforestry system for valuable timber production compliant with the CRCF requirements, modelling potential GHG emission reductions and the benefit-potential ratio (share of the CRCF-compliant net CR benefit within the total GHG emission mitigation potential). The results revealed a significant shortfall between the total GHG mitigation potential (350 kt CO₂eq) and the actual net CR benefit (205 kt CO₂eq), representing only 5 % of BW’s agricultural emissions. The benefit-potential ratio was at most 59 %, with abatement costs ranging from €59 to €153 t CO₂eq^-1. Conservative estimates to improve reliability further lowered the ratio to 24 %, pushing costs to €244 t CO₂eq^-1. While agroforestry does manifest regional CR generation potential, it is unlikely to contribute significantly to large-scale CR under the current CRCF framework, as both flaws within its quantification base and the inherent properties of nature-based CR limit its effectiveness. Although transferability is restricted by focusing on valuable timber production in BW, our results highlighted the need for harmonized emission factors, system boundary definitions (particularly indirect land use change), and a clear distinction between CR (e.g., from carbon sequestration in soils) and reduced soil emissions. We advocate balancing the use of agroforestry with more durable CR strategies and imposing caps on nature-based CR contributions to ensure robust climate action.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"20 ","pages":"Article 101201"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185203","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}

Fifty-six encounters resulted in attacks by bears that injured 59 people, with a fatality rate of 8.47 %. Victims of bear attacks frequently had serious injuries, especially to the head and neck areas of the body. Serious injuries were more likely to occur to lone individuals than to people who were in groups of two or more.

This paper compares the key elements of vulnerability and threat assessments for microbial contaminants for two Canadian provinces. Drinking water intakes of two municipalities in Quebec and Ontario, Canada, located on opposite sides of a large transboundary river impacted by Combined Sewer Overflow (CSO) discharges were used as a case study to evaluate the two provincial approaches. Québec’s vulnerability classification for microbial contaminants is data driven based on regulatory monitoring (concentrations of <em>Escherichia coli</em>) at the drinking water intake) while that of Ontario’s is model driven and dependent on the physical and hydraulic characteristics of zones around an intake. To establish a quantitative criterion to compare these two threat assessment frameworks, the impacts of a series of CSO events upstream of the drinking water intakes were simulated using a calibrated hydrodynamic and water quality model. Corresponding enteric pathogen concentrations in the intakes were estimated and used as input for Quantitative Microbial Risk Assessment (QMRA) to calculate treatment requirement levels to meet human health targets. Unlike Ontario’s threat assessment approach, Quebec’s approach provides an opportunity to investigate the effectiveness of risk reduction strategies such as an adjustment of the frequency of CSO events or corrective actions to improve treatment. Considering the influence of CSO events on log removal requirements to remain compliant with human health targets permitted the differentiation of CSO risk levels for threat prioritization.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"20 ","pages":"Article 101193"},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205335","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}

Weather conditions and emission sources affect their composition. PM_2.5 samples are collected from Lumphini and Thonburirom Parks in Bangkok from January 30 to February 8, 2024, and analysed its chemical components and the oxidative potential (OP) using the dithiothreitol (DTT) assay. A correlation analysis was conducted to assess the contributions of PM_2.5 components to and its OP in both parks. The enrichment factor and principal component analysis (PCA) were used to identify potential sources, while multiple linear regression (MLR) analysis quantified their contributions. Additionally, the study investigates the cancer and non-cancer risks associated with heavy metals. Lumphini Park has a mean PM_2.5 concentration slightly higher than Thonburirom Park. Both parks show a higher concentration of organic carbon (OC) in their PM_2.5 levels. Additionally, Thonburirom Park exhibits a higher volume-normalized OP (DTT_v) of PM_2.5 than Lumphini Park, suggesting that inhaling PM_2.5 may induce redox activity and oxidative stress. In Lumphini Park, DTT_v strongly correlate with OC, elemental carbon (EC), and metals, while in Thonburirom Park, it correlates with metals and secondary organic carbon (SOC). PCA identifies primary sources of PM_2.5 as mixed combustion sources (including vehicle emissions and biomass burning), industrial emissions, secondary aerosol (SA) formation, and road dust resuspension. The MLR analysis indicates that mixed combustion sources dominate PM_2.5 concentration in Lumphini Park, while Thonburirom Park is primarily affected by industrial emissions and SA formation. Cr is notably enriched in both parks, indicating significant anthropogenic sources. Furthermore, both parks exceed the acceptable cancer risk threshold of 1 × 10⁻⁶ for Cr, indicating an increased cancer risk for adults and children. This study presents the first-ever analysis of OP of PM_2.5 and its potential sources in urban parks of Bangkok. Average PM_2.5 concentration in both parks exceed WHO standards but remain within Pollution Control Department (PCD) thresholds. Notably, the DTT activity of PM_2.5 is higher in Thonburirom Park than in Lumphini Park. Further studies are required to identify PM_2.5 and its OP sources using more advance receptor models.

Additionally, the study sought to evaluate the well-being of residents currently residing in these coastal communities and its significant determinants. The study employed mixed methods. In-depth interviews with six community leaders and twelve residents, along with documentary reviews, were conducted to analyze the process of aquaculture-related livelihood changes. Subsequently, questionnaire surveys with 177 residents were administered in July 2024. Chronological analysis based on documentary reviews and in-depth interviews was conducted to examine changes in livelihood strategies over time, from 1967 to the present (2024). Multiple logistic regression analyses were performed to test the association between residents’ well-being and relevant factors, including livelihood-related variables, socio-demographic characteristics, and individual resilience to undesirable events. The results demonstrated that, due to changes in environmental quality (e.g., contaminated water resources, soil pollution, the introduction of invasive species, and loss of mangrove forests) and the occurrence of environmental hazards (e.g., heavy rainfall, high water temperatures, sea-level rise, and land erosion), communities’ natural assets deteriorated. Several households shifted their livelihood strategies from pure aquaculture to partial aquaculture or non-aquaculture livelihoods. Some households maintained pure aquaculture livelihoods by adopting adaptation strategies in aquaculture practices but were largely unsuccessful in coping with environmental hazards. The results of the multiple logistic regression analysis revealed that residents with pure aquaculture livelihoods were more likely to experience low levels of well-being. Furthermore, low well-being was also associated with larger family sizes, low household incomes, and low levels of financial, environmental, and social resilience to undesirable shocks. Therefore, it could be suggested that, amid environmental crises in the area, livelihood diversification is essential for pure-fishery households, particularly those with larger family sizes. Building financial, social, and environmental resilience should also be promoted to enhance residents’ well-being.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"20 ","pages":"Article 101187"},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138121","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}
