This study examines the extent, origins, and effects of MP pollution in Indian freshwater systems, emphasising essential research areas to mitigate the associated ecological and public health hazards. This study initially examines the present condition of MP contamination in Indian freshwater systems, pinpointing key sources, including urban wastewater, industrial effluents, and agricultural runoff. This article, subsequently analyse current studies regarding the effects of these pollutants on aquatic ecosystems and underscores critical knowledge deficiencies, especially in evaluating MP toxicity and its interactions with other contaminants. Emphasising the necessity for a multidisciplinary approach, we propose targeted research directions: enhancing monitoring methodologies, developing cost-effective remediation strategies, and examining the socioeconomic factors that contribute to the persistence of pollution. The significance of policy interventions and public awareness campaigns in bolstering scientific efforts to alleviate microplastic pollution has been underscored. This thorough analysis provides actionable insights for researchers, policymakers, and environmental stakeholders seeking sustainable solutions to restore the health and resilience of Indian freshwater ecosystems.</div></div>","PeriodicalId":54616,"journal":{"name":"Physics and Chemistry of the Earth","volume":"139 ","pages":"Article 103942"},"PeriodicalIF":3.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ramban District sub-basin in Jammu and Kashmir, identified as the most vulnerable area, encompasses 302 landslides. To ensure a robust susceptibility assessment, Yule's coefficient (Yc) was utilized to examine twelve landslide conditioning factors (LCFs) for LSZ preparation.

RR and TWI demonstrate negligible influence on LSZ across all sampling and resolution. LSZ exhibits considerable variation with resolution in point-based inventory. At higher resolutions (12.5 m and 30 m), raster area coverage is below 50 % of vector coverage. Conversely, at 90 m, raster coverage roughly doubles that of vector data, potentially inflating LSZ results. AUC values are higher for point than for polygon sampling.

The modified Mann-Kendall (MMK) and Sen's Slope methods are used to detect trends in groundwater sustainability over two decades (2003–2023).

These caused an increase in groundwater sustainability ranging from 0.05 to 0.15 per decade in the north, while a decline by −0.005 to 0 per decade in other areas. Rainfall shows positive correlations up to +0.6 with sustainability, while PET shows correlations between −0.3 and −0.6 with sustainability.
