From the perspective of the versatility of irrigation water, irrigation benefits are classified as internal or external; the degree of benefit is measured using the proportion of irrigation water per cubic metre of internal and external benefits. This is used as an allocation coefficient to reasonably share prices based on farmers’ water price tolerance, build agricultural water price apportionment and sharing models, and calculate the range of water prices borne by farmers and the government in the Baojixia Irrigation District in the Shaanxi Province of China. Results showed that the apportionment coefficients of farmers and government were 0.85 and 0.15, respectively. For grain crops, the farmers' price range was 0.115–0.508 yuan/m3, while that of the government was 0.516–0.909 yuan/m3; for cash crops, these values were 0.566–3.009 and 0.154–0.458 yuan/m3, respectively.

However, few studies have analysed the impact of vegetation changes on water consumption from the perspective of natural and artificial vegetation to scientifically propose that there is a moderate threshold in vegetation restoration. Taking the Ziya River Basin as an example, the daily meteorological data of 11 meteorological stations from 2001 to 2015 were used to calculate the water consumption of vegetation based on the Penman–Monteith model. The results showed that from 2001 to 2015, the vegetation coverage increased. The total water consumption increased from 2001 (2.60 × 1,010 m3) to 2005 (2.65 × 1,010 m3) and decreased from 2005 (2.65 × 1,010 m3) to 2015 (2.40 × 1,010 m3). The water consumption per unit area in descending order was mixed forests (660 mm, annual average), croplands (640 mm), closed shrublands (581 mm), deciduous broadleaf forests (528 mm), grasslands (514 mm), savannas (459 mm), and woody savannas (454 mm). Finally, the regression equation between vegetation coverage change and water consumption was y = 0.377x + 84.516, which showed that there was a proportional relationship. Therefore, attention should be given to balancing local water allocation during vegetation restoration. The results can provide a reference for vegetation restoration policies","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43082825","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 study, we propose the extended linear expenditure system-water price tolerance index (ELES-WPTI) model that combines the ELES model and the WPTI method for water pricing, Firstly, the ELES model is used to estimate the price elasticity of water demand and the basic demand for farmers of different income levels. Secondly, the WPTI method is used to simulate and analyze the affordability of farmers of different income levels for agricultural water under the dynamic change of water price standards. Finally, the ELES-WPTI model is applied to the Yinda-Jihuang (YJ) Project, China, to determine the appropriate agricultural water price. The results reveal that the farmers in the DH district have is slightly higher affordability for water price than that in HL District. As water consumption should account for less than 15% of the total production cost and 10% of the net income, the affordable water price is determined to be 237 $/hm² in the DH district and 205 $/hm² in the HL district, respectively.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46475911","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}

It is often assumed that people who reside in a riverine area have adapted to flood pulses. However, in most cases, household-level risk reduction strategies are inadequate for ensuring a livelihood resilient to floods. The objective of this study was to investigate the determinants of households' decisions on coping strategies in the Manafwa catchment, Eastern Uganda. The study was based on a field survey of 210 households supplemented with focused group discussions (6) and key informant interviews (4) conducted in the Butaleja district in March 2019. The study used the protection motivation theory framework and applied the multivariate probit model. The most common short-term coping strategy was building temporary embankments (37%), whereas afforestation (44%) was the most common long-term solution deployed. The determinants that consistently and significantly influenced the choice of coping strategies adopted were: family size, number of adult males in the family, location of the house within the floodplain and time of residence in the affected area (P > 0.05). For policy purposes, this study recommends that the relevant stakeholder interventions should consider these determinants, in order to enhance the adaptive capacity of rural households to flooding.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45005574","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}

Despite a relatively low public profile, it affected approximately 20% of households in England and Wales in 2020. Currently, as many as 34% of bill payers report struggling to pay fairly frequently. This comprehensive review examines definitions, prevalence and manifestations of water poverty through an analysis of 354 grey and academic documents, dating between 1985 and 2022. Synthesising the literature revealed how water poverty is a structurally-produced problem, reflecting trends in sector governance and wider societal processes. In the 1980 and 1990s, water poverty was characterised by household disconnections, as defaulting customers were considered a drain on the financial health of newly privatised utilities. Owing to civil society opposition, by 2000 water poverty became a technocratic problem of affordability and debt. Despite certain legal protections for vulnerable households, structural drivers of water poverty continued unresolved and rates continued to rise, peaking in 2013/2014. Contemporary discourse emphasises extending availability, accessibility and flexibility of support, but structural drivers remain hidden. It is, therefore, highly questionable whether the water sector in England and Wales can fulfil its commitment to ending water poverty by 2030.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48485440","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}

We found that in 72% of the springs of semi-urban areas, the discharge rate has been decreasing over the past decade. In addition, the springs of such areas were exposed to higher contamination of biological pollutants compared with the rural areas. Synthesis of spring research in Nepal shows that springs of Nepal are degrading at an alarming rate where 16% had already dried up and about 60% have declining discharge, mainly due to declining rainfall, haphazard infrastructure development, and excessive spring resource exploitation. In response to the degrading springs and water crisis, several initiatives have been made, yet, they are scattered, focused on limited springs, and not adequate to curb the current rate of spring degradation. We argue that the existing policies that are intended to operate in a top-down approach at the basin and watershed level are not effective in addressing local water issues at the springshed level.","PeriodicalId":49370,"journal":{"name":"Water Policy","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44469462","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}
