In this paper, we study institutions and processes using Amartya Sen's conception of justice. We review the outcomes by assessing agencies, actions and processes involved in the implementation of the SBM-R programme. The findings are analysed using the Sanitation Well-being Framework. Sanitation well-being is achieved when an individual is able to experience the sanitation life cycle stages of acceptance, construction, utilisation and maintenance of safe disposal, which are part of the framework. The capability factors grouped under personal, cultural, structural, environmental and service elements of the framework determine the sanitation environment facilitated by the state. Failure in experiencing one of the life stages leads to slippage in sanitation, where people resume open defecation, despite possessing toilets. The paper presents a review of literature on the political, technological and structural issues in programme implementation, followed by an analysis of 42 interviews and 12 focused group discussions of state and non-state actors conducted in rural Shravasti, Uttar Pradesh, India. We found that slippage is prevalent in the field site and identified 26 capability factors (expansion and constraints) that led to slippage in sanitation.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43081428","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}

In addition, one of the main regions in China for grain production is the Yellow River Basin. Based on this, we utilize a Difference-in-Difference (DID) empirical technique to assess the impact of the agricultural water-saving policy on food security using data from prefectures in China's Yellow River Basin from 2000 to 2020. According to the estimated results, grain production has greatly increased as a result of the agricultural water-saving policy. This conclusion still holds when other water-related policies are considered. The agricultural water-saving policy may enhance other input factors in grain production by assuring water demand, which is one possible mechanism of the influence. The empirical results show that the policy indeed increases the water productivity in agricultural production, which will ensure the effective water utilization in agricultural production, and the grain sown area, which is the most important production factor in agriculture. In heterogeneity analysis, the impact of the policy on food security is the largest in the lower reach, followed by the middle reach and the smallest in the upper reach in the Yellow River Basin.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43721484","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}

The current study presents an approach for addressing the challenges in UWI, specifically in water supply and sewerage. The article argues a need for a paradigm shift that simultaneously includes the sustainability and resilience aspects throughout the life cycle of UWI. The article further highlights the issues in the prevailing approach of centralized infrastructure and demonstrates the necessity of moving away from such an approach and shifting towards decentralized infrastructure. Understanding the factors accelerating decentralization to attain a paradigm shift to decentralization is necessary. Hence, the study first identifies the drivers of decentralization. Secondly, the need for an appropriate scale to be considered while implementing decentralized UWI is highlighted in this study. Furthermore, the effect of the scale of infrastructure is discussed through the trade-offs between life-cycle costs, ease of governance, resilience and recycling benefits. The approach of scaled decentralization outlined in the study will be useful for developing countries to plan new infrastructure and also for developed countries to replace the ageing UWI to create future sustainable and resilient urban systems","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47991217","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}

Practitioners have been seeking methods to determine the ecological flow of rivers or lakes and how to ensure its implementation. Taking the Dingnan River watershed as a case, drawing on the experience of ‘Hedging rule’, the ‘Determination-Assessment-Reduction’ for the ecological flow nexus approach (the D-A-R approach) is introduced, which includes the determination of the annual ecological flow process through the river section, the assessment of water scarcity degree of the watershed and various water reduction strategies, respectively, and respond to the three scenarios of ‘general type, saving type and constrained type’ during the gap period. The results show that it is possible to use the D-A-R approach to proactively and dynamically adjust the ecological flow according to the probability estimate of that amount of water inflow per month, which the adjusted ecological flow threshold can better adapt to water scarcity at different levels and alleviate the contradiction among domestic, production and ecological water in the watershed during the dry period.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46821326","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}

In this work, a high-precision hydrodynamic model was used to evaluate the construction effect of each LID facility scheme. And the fitted functional relationship was used to describe the law between the LID facility construction area and the construction effect. Finally, a genetic algorithm was used to automatically optimize the best LID facility construction scheme. Applying this method to the actual urban LID facility planning and construction, the optimal solution law is that the construction effect of single and combined LID facilities increases with the increase of construction cost. In the same low-cost construction scheme, the construction effect of combined LID facilities will be lower than that of single LID facilities, but with the continuous increase of construction cost, the construction effect of combined LID facilities will eventually be better than that of single LID facilities.

The study of water cycle health evaluation has provided guidance to urban planning, development, and resource management. In this study, a water cycle health evaluation method based on EFAST-Cloud model is proposed, and Henan Province of China is selected as a typical study area. The water cycle health status is evaluated from four dimensions of water ecology, water quality, water abundance, and water utilization. The evaluation results are compared with those of fuzzy comprehensive evaluation as well. It is shown that the established EFAST-Cloud model results of assessment are consistent with the Fuzzy comprehensive evaluation method, while it has the advantage of being able to evaluate the proportion of each grade in detail by reflecting the randomness and fuzziness of the evaluation. According to the statistical data from 2007 to 2018, the whole area is in a sub-healthy state. During the 12-year period, the health status of the water cycle has been improved year by year.
