Failure to increase the provision of sanitation services is primarily a governance problem, but general governance initiatives will not be effective without practical measures to strengthen regulation and specifically address corruption. Zambia has developed an impressive regulatory framework including plans to cover non-sewered sanitation, however, this regulatory framework requires further strengthening especially in terms of the capacity of regulators.","PeriodicalId":393895,"journal":{"name":"Water Science Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129059613","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}

Hundreds of large dams (≥ 100 metres) have been constructed since 2000, with hundreds more under construction. Analysing the physical attributes of these dams presents a concerning image. While these dams create expansive reservoirs with larger surface areas, their storage capacity/volume is limited: they have inefficient surface area-to-volume ratios ('S2VR'). The unprecedented size of these dams, along with the expansive surface area of their reservoirs, indicates severe environmental costs. These costs include damaging river ecosystems, mainly through ecological disturbances to the aquatic ecosystem; and greenhouse gas emissions (GHG). Other ecological costs that come with the larger S2VR include a problematic high evaporation rate and compromising the biodiversity of a wider area. Thus, the safety and environmental aspects of these ecologically damaging and unsustainable large dams should be robustly scrutinised.","PeriodicalId":393895,"journal":{"name":"Water Science Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122225935","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}
