The present review highlights the zooplankton research conducted over the last decade (2014-2024) in the Indian Sundarbans, with a focus on research trends, species distribution, hydrological associations, and long-term monitoring and conservation strategies. The study reveals a surge in zooplankton research after 2019, with an emphasis on both small- and large-scale studies. However, tidal creek/canals remain less explored compared to rivers. A lack of methodological standardization in zooplankton research is evident across the Indian Sundarbans. The Saptamukhi-Thakuran-Matla river stretch exhibited the highest species diversity, with 70 species recorded. Similarly, the tidal creeks and canals of Sagar Island were identified as species-rich habitats, with 63 species reported. Oithona brevicornis was found in seven riverine stretches, while Paracalanus parvus and Labidocera euchaeta were each recorded from six rivers, but Bestiolina similis was mostly reported as the numerically predominant zooplankton species. Salinity emerged as the most influential hydrological factor for zooplankton distribution, followed by dissolved oxygen and water temperature. However, increasing pollution, climate change-induced cyclones, salinization, and human activities are threatening zooplankton communities of the Indian Sundarbans. Furthermore, the review underscores the need for long-term monitoring strategies in the Sundarbans, by addressing the integration of remote sensing method, automated devices, data repositories, and ecological modeling approaches. Additionally, the present review recommends future policies for zooplankton conservation, emphasizing habitat protection, water quality assessment, stakeholder engagement, and securing funding to implement long-term monitoring initiatives.</p>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 2","pages":"217"},"PeriodicalIF":2.9,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143073458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This paper proposes an intuitionistic fuzzy linguistic aggregation method for heterogeneous linguistic assessment information, to solve the multi-index assessment problem containing heterogeneous linguistic information.

Firstly, the multi-granularity heterogeneous linguistic terms are effectively transformed by the defined linguistic scaling function. Secondly, the formula of the deviation coefficient between linguistic terms is given. By fully considering evaluators' risk preferences, the intuitionistic fuzzy linguistic numbers are determined using this formula. Simultaneously, the assessment index's objective weight is obtained based on the distance calculation formula of intuitionistic fuzzy linguistics. Finally, the intuitionistic fuzzy linguistic multi-attribute assessment (IFLMA) method with heterogeneous linguistic assessment information is proposed.

This study pioneers the integration of social-ecological system theory with multi-criteria decision-making methods to innovatively construct a dynamic coupling assessment framework. This framework employs the AHP-DEMATEL method to identify causal relationships and feedback mechanisms between indicators, while utilizing the VIKOR method for comprehensive quantitative risk assessment.

In the last few decades, significant improvements have been made in efficiency and economy to remove contaminants from wastewater using several adsorbents. However, less attention was paid to the regeneration of used adsorbents. Aside from the adsorbent's high adsorption performance, the disposal of spent adsorbents is an environmental concern. Regeneration is an important aspect to stimulate the adsorption efficiency of the spent adsorbent for wastewater treatment. This article reviews the various regeneration techniques like electrochemical regeneration, biological regeneration, thermal regeneration, ultrasound regeneration, and chemical regeneration in detail that have been performed for the renewal of saturated adsorbents. In the ultrasonic regeneration technique, Fe₃O₄-loaded coffee waste hydrochar adsorbent showed 100% regeneration efficiency (RE) after 1.3 h at the power consumption of 300 W/L. Electrochemical regeneration of granular activated carbon, Nyex, graphene and titanium dioxide composite, and Nyex 1000 showed 100% RE after 3, 0.16, 0.12, and 1.5 h, respectively, with electrolyte Na₂SO₄ and NaCl. In the regeneration technique, powdered activated carbon showed 90% RE after 48-72 h. Immobilized fungal biomass (Rhizopus nigricans) adsorbent showed 111-115% RE with base (0.01 N NaOH, NaHCO₃, and Na₂CO₃) solvent. The present study addresses issues including waste generation, adsorbent potential and efficiency, eco-friendly techniques, and the release of adsorbed pollutants in regenerating saturated adsorbents. The mechanisms of adsorbent regeneration were thoroughly examined, highlighting the significance of the regeneration process in adsorption. Furthermore, this review discusses the advantages of hybrid regeneration techniques like microwave-activated ultraviolet-advanced oxidation, electro-peroxide approach, electrochemical and electrothermal methods, and the secondary use of spent adsorbents as catalysts, fertilizer, cementitious materials, secondary adsorbent bio-fuels, etc. Using saturated adsorbents is a practical technology for sustainable wastewater treatment that has the potential to minimize pollution and promote a circular economy. This review concludes with a discussion of the present challenges in the regeneration of the used adsorbents, as well as future directions for ensuring the system's feasibility from an economic and environmental standpoint for use on an industrial scale.</p>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 2","pages":"215"},"PeriodicalIF":2.9,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143062933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This study analyzes changes in forest cover and the evolution of forest spatial configuration using Landsat satellite imagery over the past three decades (1990-2020) in Azad Jammu and Kashmir (AJK), Pakistan. To achieve the objectives, landscape metrics and forest fragmentation analyses were applied. Additionally, a pattern-based spatial analysis was conducted to examine forest cover changes in the study area. Overall, the forest cover change from 1990 to 2020 was 74 km² (- 1.75%), with an average annual forest cover change rate of - 2.5 km² (- 0.06%) for the entire study period. A gradual decline in forest cover was observed between 1990 and 2020, with the most significant decline of - 29.92 km² from 2000 to 2010. The forest fragmentation analysis reveals that the core forest areas (> 500 acres) are increasingly being divided into smaller (< 250 acres) and medium-sized (250-500 acres) patches. Landscape metrics at the class level show that, with a few exceptions, the overall forests in AJK remain connected and aggregated. Based on forest cover and ecoregions in the region, the pattern-based spatial and dissimilarity analysis identifies forest hotspots (areas of gains or losses) and clusters. To conserve, restore, and monitor the forests in the study area, decision-making and policy-making institutions can establish conservation priorities.

Climatic conditions, an acute challenge in sub-Saharan Africa (SSA), where access to mitigation technologies remains limited, have heavily influenced these lands. This study explores GHG contributions from crop production and their devastating and deteriorating impacts on the economy and environment and proposes a sustainable solution. The research design includes the application of various measuring metrics to examine the intensities of climate variabilities using panel data and real-time data from remote sensing (RS). Both sources of data were verified via a blinded comparison of CO&lt;sub&gt;2&lt;/sub&gt;eqKg emitting capacity from leading cropland emitters in SSA, as a method to eliminate flawed data. Estimate stochastic frontier analysis (SFA) was used to compute the recorded data from 1988 to 2022, in combination with QGIS and Google Earth SFA proved to be the most effective model for assessing the impacts of climate change on production since it was invented and introduced by Aigner, Lovell, and Schmidt in 1977. The deployment of the Sentinel-2 satellite has facilitated the capture of real-time images of land use and land cover (LULC), which revealed an annual average crop yield loss of 58% rendering only 0-40% of the cropland effective for potential crop growth. The investigation further showed that among six closely monitored countries, South Africa had the highest CO&lt;sub&gt;2&lt;/sub&gt; equivalent emissions (kg), peaking at 64 kg CO&lt;sub&gt;2&lt;/sub&gt;eq/kg in 1990 and declining to 58 kg CO&lt;sub&gt;2&lt;/sub&gt;eq/kg in 2017. Ethiopia, the second-largest emitter, had a 2007 emission rate of 24 kg CO&lt;sub&gt;2&lt;/sub&gt;eqKg. Nigeria is next, contributing a mean value of 21 kg CO&lt;sub&gt;2&lt;/sub&gt;eq/kg. It was established that in each of the three (3) nations (South Africa, Ethiopia, and Nigeria) defined as heavy emitters in SSA, the annual contribution quota to global GHG emission is far above what is emitted in industrialized nation. The study revealed that an estimated total cropland of 10,881,657.5 square hectares in North Central Tier (NCT) 2 (Nigeria, Niger) and North Central Tier 3 (Sudan, Ethiopia) is considered the hotspot of the GHG emission index in SSA.
