Nagpur, despite its inland location, faces recurrent flooding due to inadequate stormwater infrastructure and encroachments on natural water bodies. This study explores the potential of Sustainable Urban Drainage Systems (SuDS) to mitigate urban flooding in Nagpur by simulating the performance of seven SuDS components—Rain Barrel, Rooftop Disconnection (RD), Green Roof, Pervious Pavement, Bio-retention, Rain Garden, and Infiltration Trench (IT)—individually and in combinations using the Storm Water Management Model (SWMM). A flood-prone sub-catchment in the city, comprising 69% impervious area, was selected for simulation. The study was conducted for five rainfall return periods (2, 5, 10, 25, and 100 years) to test performance under varying intensities. Among the components, RD and IT showed the highest effectiveness, reducing runoff by approximately 57% and 15%, respectively. Their combination (RD + IT) achieved a runoff reduction of nearly 67%. Other combinations, such as RD + Bio-retention and RD + Rain Garden, also performed well (~ 60% and ~ 58% reductions). These decentralized interventions promote groundwater recharge, support water reuse, and offer scalable, low-cost solutions for urban flood management. The findings highlight the applicability of SuDS in dense urban areas of India and underscore their relevance in retrofitting existing drainage networks. This study contributes to the limited empirical research on SuDS in tropical developing countries and offers a practical foundation for integrating such systems into local planning and national disaster resilience strategies.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"49 5","pages":"751 - 758"},"PeriodicalIF":1.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetics plays important role in susceptibility for the disease. India has high burden of NAFLD, however, information on its genetic susceptibility is lacking for Sikkim, a north east Himalayan state of India. We conducted a pilot study to determine the risk of <i>PNPLA3</i> gene polymorphism for NAFLD in this region. In a case control study including 30 cases and 25 controls, DNA was extracted from peripheral blood of the participants. SNP rs738409 [C > G] of <i>PNPLA3</i> was detected by PCR followed by RFLP. Risk of NAFLD was higher in variant homozygotes and heterozygotes in comparison to the wild type homozygotes. Although the increased risk was not statistically significant, a large- scale study is required to find any possible association of this polymorphism with NAFLD in this Himalayan state. In addition to this, high frequency of the variant allele [G] observed in the control group (0.4) warrants further study to explore its putative association with NAFLD in this region.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"49 5","pages":"729 - 731"},"PeriodicalIF":1.1,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
