In the north of India, the mountainous state Uttarakhand is one of the worst sufferers of recurrent FF causing enormous loss to the forest ecosystem goods and services (FES). Hitherto, the monetary loss estimation based on the norms of Forest Deptt. considers only timber, resin and tree regeneration, grossly undermining the other important tangible benefits of forest ecosystems making compensation policy ambiguous. We devised simple methodology to estimate the quantities and monetary value of various forest ecosystem goods (FEGs) lost to FF on per ha forest area basis across three major forest types of Uttarakhand. Study involved a total of 5040 sample plots (840 for trees, 1680 for shrubs and 2520 for herbs) across the 42 study sites (burnt forest and adjacent unburnt control forest) considering severity of FF, slope, aspect and altitude of the forests, classified using Moderate Resolution Imaging Spectroradiometer (MODIS), Simple Network Paging Protocol (SNPP) and Visible Infrared Imaging Radiometer Suite (VIIRS) satellite data. Monetary loss value of the FEGs thus estimated (mean= Indian Rupee (INR) 1,30,387 ha⁻¹; range= INR 9,595–3,52,752 ha⁻¹) using the Market Price Method for marketed goods and stakeholder’s Contingent Valuation Method for non-marketed goods was found highest for timber (59 % of the total loss), tree regeneration (15 %), fuelwood (8 %), wild edibles (7 %), leaf litter (4 %), resin (3 %), fodder (2 %) and MAPs (1 %). Moderate fire accrued significantly (<em>P</em> &lt; 0.049) greater loss than the low severity fire, and the loss was positively related to altitude (<em>P</em> &lt; 0.048), slope (<em>P</em> &lt; 0.039) and aspect (<em>P</em> &lt; 0.041) of the forests. Thus, the monetary loss due to FF we estimated was 65–90 times greater than it was reported so far in Uttarakhand. We recorded some benefits associated with the FF such as better growth of grasses, plant species richness and yield of a few wild edibles. This pioneering study carried out under the restrictions of Covid-19 will redirect the attention of policy makers, forest managers, the media, and society toward the economic and ecological consequences of FF, and calls for detailed studies to better understand the loss of FES to FF.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"21 ","pages":"Article 100651"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144481648","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}

Artificial destratification technologies have emerged as potential solutions to mitigate these effects and improve water quality. This systematic review examines 194 studies from databases such as Web of Science, Scopus, MDPI, and ASCE, covering research from 1990 to 2024. The review evaluates various destratification methods, including mechanical mixers, bubble aerators, floating intakes, suspended curtains, multi-level offtakes (MLOs), and gradual entrainment level inverters (GELs), for their effectiveness in improving oxygenation and reducing nutrient buildup. It highlights that bubble aerators perform best in smaller water bodies, while mechanical mixers, though less common, offer cost-effective solutions for larger systems. However, mixers alone show limited effectiveness in large reservoirs, and their combination with bubble aerators can enhance system performance at increased operational costs. This review fills a critical gap in the literature by synthesizing available data on destratification technologies and their role in restoring ecological balance in stratified waters.

This study investigates the interrelationships among climatic, geographic, soil, and anthropogenic factors influencing drought risk in the Upper Phetchaburi River Basin. Ten key drought risk factors—precipitation, aridity index, slope, elevation, soil texture, drainage, fertility, erosion, land use, and land cover—were spatially analyzed using Agglomerative Hierarchical Clustering and Pearson Product-Moment Correlation. The analysis revealed both direct and inverse relationships among these variables, underscoring the compounded effects of climate, land use, and soil dynamics on drought vulnerability. A particularly strong correlation between climatic and anthropogenic variables suggests a spatial-temporal alignment that intensifies drought conditions. Additional significant correlations—including precipitation–aridity index, aridity index–land use, and slope–soil fertility—further emphasize the integrated nature of environmental processes regulating drought susceptibility. Clustering analysis identified three distinct groups: (1) precipitation, aridity index, and soil erosion, illustrating how reductions in precipitation and aridity index accelerate soil degradation; (2) soil properties—texture, drainage, and fertility—are crucial in highlighting their roles in water retention, nutrient availability, and vegetation resilience, particularly in slope terrain; and (3) elevation, land use, and land cover, demonstrating the combined effects of topography and anthropogenic activities on drought dynamics. These findings underscore the urgent need for sustainable land management, targeted ecosystem restoration, and climate-adaptive policies to mitigate drought risks.

In river corridors, riparian vegetation has been identified as a potential natural barrier for plastic particles while transported downstream. Knowledge of the trapping dynamics appears fundamental for understanding the role of riparian barriers in mitigating plastic pollution. However, to date the effects of the foliage distributions of riparian flexible plants and of turbulence on the plastic particle retention dynamics have not yet been studied. This work aims to fill these knowledge gaps including also the influence of the particle characteristics (i.e., density, size, and shape) and of the vegetation structure (i.e., number of branches and leaves). Laboratory experiments were performed in steady flow conditions over a fixed dune bed, using just submerged flexible foliated plastic plants. Results show that particle retention is highly influenced by density and shape. Among the tested disk-shaped particles, those with higher density (1.4 g/cm³) exhibited retention rates up to 93 %, largely at the channel bed structures. At equal density (1.04 g/cm³), irregular-shaped particles were retained at nearly twice the rate of disk-shaped ones (20 % vs. 9–10 %), with vertical dispersion influenced by turbulence. Turbulent Kinetic Energy (TKE), expressed as dimensionless TKE/U² values, showed a non-linear relationship with retention: values below ∼0.0015 were associated with enhanced trapping, while higher turbulence reduced retention, likely by promoting resuspension and weakening particle adhesion. Vertical profiles of TKE/U² varied with leaf configuration, suggesting that vegetation structure modulates turbulence intensity along the canopy. These findings provide a quantitative framework to evaluate microplastic trapping efficiency in vegetated riparian zones, offering insights into natural and engineered nature-based solutions for mitigation of plastic pollution in aquatic systems.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"21 ","pages":"Article 100645"},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144243013","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}

Existing ammonia emissions modelling does not consider how national scale net zero land-use targets are spatially distributed which means these onward impacts may not be adequately assessed. Using England as a case study area, we employed spatial land allocation (LA) modelling to apply these measures on suitable land. We then used emissions modelling to estimate the resulting changes to livestock and chemical fertiliser ammonia emissions at a 5 km grid resolution. To assess the effect of LA modelling on results, we also carried out non-land allocation (NLA) modelling which did not consider the suitability of land, instead distributing the measures uniformly across all agricultural land. The resulting total reductions due to LA modelling of measures was 15.9 kt-NH₃, or 10.5 % of total livestock and chemical fertiliser emissions in England. The NLA approach resulted in similar total reductions, but their distribution was markedly different, particularly for peatland restoration and afforestation measures.
