This study uses annual maximum streamflow data from 17 hydrologic stations along west-flowing rivers in Kerala, India, for Non-Stationary (NS) FFA. The Generalized Extreme Value model with a linear temporal location parameter worked effectively for five stations. Kidangoor and Pattazhy stations must account for non-stationarity for longer return periods (RPs) (>50 years), whereas Neeleeswaram and Perumannu stations must for shorter RPs (<50 years). An extensive study was conducted for Neeleswaram station (Periyar basin) by simulating NS models incorporating four large-scale climate oscillations as covariates. The stationary assumption underestimated flood return levels of 2-year RP by about 61% which increases the flood risk leading to failure of hydraulic infrastructures. It was observed that the best fitted climate-based NS model achieves stationary return level of 150-years RP at 25-years RP itself. The study proved that the climate-based NS models captured the 2018 August Floods in Periyar basin better than stationary and time-based models. The regional variability in FF curve behaviour concludes that NSFFA for Kerala cannot be generalised and must be done at a local-scale.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"19 ","pages":"Article 100137"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49020411","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 systematic bibliographic review manually screened 47 articles under four categories, including Water and health; Climate and water; Climate and health; and Climate, water, and health, from 2010 to 2022. This research is critical for ensuring the availability of safe drinkable water and public health adaptation to climate change in Bangladesh. The findings revealed that cholera, infant diarrhea, pneumonia, dengue, and malaria are prevalent in the vulnerable groups. The present number and distribution of regional healthcare centers demonstrates potable water procedures and medical centers are insufficient relative to demands. Overall, this study revealed several techniques that help guarantee safe potable water, including holding rainwater, pond sand filters, and drinkable water supply. A knowledge-based approach was used to propound an adaptation framework for tackling the impact of changing climate, especially on safe water availability and public health, and also identified six research gaps. This research serves as a roadmap for future scholars, academicians, practitioners, and policymakers and indicates the need for more progress in the database on national climate change research.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"18 ","pages":"Article 100133"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47535622","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}

Impacts can be found in the health sector, where labor productivity can be affected, in agriculture, where the quality and quantity of food produced can be reduced, and in tourism, real estate, aquaculture/fisheries and other sectors which rely on environmental quality and ecosystem services. Despite these well-known impacts, finding economy-wide effects of water quality on economic activity can be elusive. In this paper we attempt to fill this gap by using new data on economic activity and water quality for 17 countries from 1990 to 2014 and a panel fixed-effect model that accounts for endogeneity between pollution and economic growth through the direction of streamflow. We find that when rivers become very heavily polluted, regions downstream see reductions in economic growth, losing between 1.4 and 2.5 percent of economic growth, depending on development level and the level of pollution. These losses imply that in many places, the costs of environmental degradation are severely under-estimated and pollution is well above efficient levels.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"17 ","pages":"Article 100130"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45578814","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}
