Based on a series of panel data analyses on Chinese provinces between 2004 and 2015, this study empirically examines the impact of decentralization and interest groups on water policy implementation, leading to three main findings. First, fiscal decentralization has a significant positive effect on policy output as measured using per-capita provincial expenditures on industrial wastewater. But it has no significant influence on policy outcome as measured by per-capita emissions of chemical oxygen demand. Second, while increasing environmental decentralization at the provincial level tends to increase provincial expenditures, wastewater discharge also increases. Third, increased industrial contributions to the provincial economy are associated with increased environmental spending from the province, yet foreign trade and environmental petitions do not have the expected impact. The results suggest that China’s decentralization reforms appear to have increased provincial policy responses without improving the actual environmental outcomes. Experiences from authoritarian China may provide lessons for other countries.","PeriodicalId":48492,"journal":{"name":"Water Economics and Policy","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43026330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the focus has historically been on large-scale dam-based schemes, farmer-managed small-scale irrigation (SSI) has gained increased attention in recent years. Using data from Ethiopia, Tanzania and Ghana, we first examine patterns of adoption of different SSI technologies. Next, we employ hierarchical modelling to examine which variables are associated with observed adoption patterns and cluster effects that explain variation in irrigation adoption. We document significant cross-country variation in adoption patterns and find a positive association between plot-level use of SSI and the intensity of agricultural labor and inorganic fertilizers applied on the plot. Community-level intra-cluster correlation (ICC) is the highest in Tanzania, where gravity-fed irrigation is most common while farm-level ICC is the highest in Ethiopia where motorized technologies are more common. These results suggest the need for localized investments to ease locale-specific potential constraints. For example, easing possible liquidity constraints to acquiring motorized technologies can be more effective in Ethiopia while the construction of dams and improved conveyance systems, as well as the strengthening of community-based irrigation management (e.g., through Water User Associations (WUAs)) can be more effective in Tanzania. Further research is needed to understand pathways for selected plot-level characteristics that affect use of SSI including status of plot ownership and the gender of the plot manager.","PeriodicalId":48492,"journal":{"name":"Water Economics and Policy","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48392021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water in the river has been over-allocated, which has led the Colorado River Delta in Mexico to dry up, thus endangering the indigenous species. The two nations made several temporary, costly allocation agreements to transfer water to the Delta for ecological restoration. However, there is still no long-term economic solution for the Delta, which is what this study aims to address. In this work, I investigate solutions for rerouting water to the Delta that will minimize costs without causing excessive damage to the agrarian economy in the US. The cost of conserving water for the Delta was analyzed using numerical simulations with crop data from the Imperial Irrigation District in California. The objective is to find a policy that would help allocate 100,000 acre-feet per year to the Colorado River Delta at a minimum lifetime cost. Two scenarios are studied that would yield enough water for a sustainable restoration of the ecosystem: fallowing croplands and changing the irrigation system to be more water-efficient. Results indicate that fallowing 20,000 ac of alfalfa would be the least costly way of accumulating this resource at a cost ranging from $5.5 million to $13 million per year for a 31-year time horizon. This paper provides new insight into ways in which the US and Mexico can secure the future of ecosystems like the Colorado River Delta.","PeriodicalId":48492,"journal":{"name":"Water Economics and Policy","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48618514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study identifies the extent of water contamination through standardized laboratory tests from the metropolitan city of Karachi, which is the largest city of Pakistan. Moreover, a household survey data is used to estimate a health production function focusing on waterborne diseases. The study finds the average probability of waterborne diseases and estimates the cost of illness from the sample data. Probability of illness and defensive behavior are proxied by the prevalence of diarrhea and household expenditures on water treatment, respectively. The results show that the likelihood of getting diarrhea is higher among households who make less expenditures on water treatment. Water contamination positively affects and filtration negatively affects the prevalence of diarrhea in the city. Further, the study finds that the total direct monthly health cost of untreated water consumption for the entire population of Karachi is PKR 80.7 million.","PeriodicalId":48492,"journal":{"name":"Water Economics and Policy","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44287747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
