This article estimates the benefits of potable water quality improvements in Kajang Municipality in the state of Selangor, Malaysia, using the avertive cost method. Households were willing to pay MYR 322 annually to improve potable water quality. This represents about 80% of their average annual water bill. The present value of aggregate benefits over a period of 30 years at various social discount rates ranged from MYR 301 million to MYR 768 million. These estimates can be used as a reference for public investment criteria. The findings suggest that there is merit in an upward revision of water tariffs if they provide improvements in water quality.  相似文献

Abstract

Agriculture is the largest user of water in Turkey with 75 percent of the total consumption. Turkey has developed 50 percent of total irrigable land so far. Water is a limiting factor for agriculture throughout much of Turkey. The amount and distribution of precipitation is quite uneven. Turkey, like many countries today, faces challenges in efficiently developing and managing its agricultural water resources while trying to protect water quality and the environment. However, Turkey has some difficulties and problems on water use for agriculture. Current institutional framework and legal regulation, monitoring and evaluation activities are investigated, and agricultural water use and irrigation development are studied. Problems with the lack of data on environmental effects of irrigation and water pricing are underlined. Evaluation of the current situation ends in the conclusion that Turkey needs a comprehensive monitoring and evaluation system both at basin and scheme level, and rehabilitation of irrigation systems for efficient water use in agriculture.  相似文献

Hydrochemistry of 27 elements and 8 anions in tropical surface waters of the Terengganu River (Malaysia) was investigated. Dissolved elemental concentrations changed significantly with distance along the flow path depending on redox and pH, often reflecting natural enrichment. High nitrate concentration is probably associated with untreated waste water input, agricultural runoff, and atmospheric input. Overall, the quality of water was found to be acceptable with the exception of a few sites. Dilution effects, water residence times and the weathering of local mineral deposits exert major control over hydrochemistry.  相似文献

Bolivia is one of the countries on the American continent with the lowest rates of access to water, a situation that has caused confrontation between civil society and water utility managers in some cities. This research describes the water access scenario in Sucre, the capital of Bolivia, together with the key challenges faced by the company that manages the water services in the city. The case of Sucre is an example of how poor water governance can generate inefficiencies in the management of the service. Taking this into consideration, policy and institutional reforms are recommended to facilitate decision making aimed at improving the current situation of access to water.  相似文献

Water Crisis     
Asit K. Biswas 《国际水》2013,38(4):363-367
Abstract

Water crisis was not considered seriously at the Dublin and Rio conferences. It was put on the world agenda primarily by the Stockholm Water Symposia. Water management is likely to change more during the next twenty years compared to the past 2,000 years. The paper reviews the global water situtation based on the latest data available. In terms of water availability, it concludes that one can now be cautiously optimistic of the global water future. If there is to be a crisis, it is likely to be for two reasons: water quality and lack of investments. Neither of these two issues are receiving adquate attention at present. The roles IWRA can play in the future are briefly outlined.  相似文献

This paper reviews water pricing reform in China after 1980, including framework, process, forces and considerations. China collects a water resources fee, a water supply tariff for hydraulic engineering, an urban water supply tariff, a wastewater collection and treatment tariff, and a pollutant discharge fee. The reform has been an exploration process. In theory, a comprehensive, systematic and advanced policy and framework have been developed. However, in practice, the reforms fluctuate among economic, social and environmental targets; do not comply with the reform objectives; and are heavily affected by external social and economic factors rather than by internal factors.  相似文献

Abstract

Water is vital for the survival and development of every community or society. The health of a given community is reflected to a large extent in the water quality of the community's available water resources. In Ghana, efforts have been made since colonial days to supply both the urban and the rural communities with potable water to enhance the rapid socio-economic development of the country. It is economically viable due to the remoteness of most of the rural communities to supply them with potable water from local sources such as groundwater. The urban water supply systems are mainly based on surface water sources. With the ever-expanding population, there is a need to improve freshwater resources conservation and management in order to avoid impending shortages. To ensure the total coverage of all rural and urban communities by the year 2020, a huge capital outlay of $1 billion and 51.5 billion, respectively, is needed. Most of these funds are expected to come from the private sector, both local and foreign, with the Government making some substantial contribution.  相似文献

Abstract

India’s public irrigation sector is one of the largest in the world in terms of number of large reservoirs, total storage capacity and irrigated area. But poor financial performance has been threatening its sustainability. Hence, many changes have been introduced in the area of water pricing over the years. But studies that focus on the issue of financial recovery are scanty. Analysis presented in the article shows that despite a substantial increase in area under irrigation, there has been a consistent decline in revenue generated from irrigation fee collection across states. The recovery rate of irrigation fees has been better in less developed states than in more developed states.  相似文献

Abstract

In certain circles, demand management is seen as one and the same thing as economic pricing. This thinking is stimulated by the Dublin principle that water should be considered an economic good. But is this reasoning correct? Is economic pricing an adequate means to reach more desirable levels of demand? There is considerable misunderstanding about what the concept of water as an economic good implies. In this paper it is argued that water pricing should primarily serve the purpose of financial sustainability through cost recovery. Moreover, in water pricing, adequate attention should be given to equity considerations through, for example, increasing block tariffs. Instead of economic pricing there is a need for defining a reasonable price, which provides full cost recovery but which safeguards ecological requirements and access to safe water for the poor. Giving a reasonable price to water has the additional benefit that it sends out a clear signal to the users that water should be used wisely, but the prime target of water pricing remains cost recovery. A major argument of neoclassical economists is that economic pricing of water will facilitate the re-allocation of water from sectors with lower added value (such as agriculture) to sectors with a higher added value (such as urban water use). However, the value of alternative uses of irrigation water is often grossly over-estimated. Adequate and effective regulations may suffice in order to achieve the optimal allocation of water resources.  相似文献

Marginal cost pricing of running water and sewerage services haslong been the default recommendation of economists and natural resource specialists to firms and local governments. However, optimal water rate calculation considering the optimal number ofmeters has not been thoroughly treated in the literature. The socially optimal number of meters crucially depends on the price of water charged by the Water Company. This is because whether or not metering is justified in economic terms will depend on the decline in water consumption and therefore in water production costs. This paper combines the optimal pricing and theoptimal metering issues in one optimization problem. Both in a centralized and in a decentralized way, the optimal number of meters is determined simultaneously with the optimal per unit water rate. The Rateable Value System (RV) (i.e. the Status Quo or benchmark regime) is confronted with Universal Metering (UM),Optimal Metering (OM) and Decentralized Metering (DM) in terms of optimal water rates and the socially optimal number of meters.Except for RV, the results of (UM), (OM) and (DM) all suggest that price should be set equal to marginal cost and that the optimal number of meters will be determined by a functional form combining water, metering costs and water demand characteristics. Conclusions and policy recommendations are drawn from the theoretical analysis.  相似文献

Difficulties in monitoring groundwater extraction cause groundwater regulations to fail worldwide. In two counties in north-west China local water authorities have installed smart card machines to monitor and regulate farmers’ groundwater use. Data from a household survey and in-depth interviews are used to evaluate the effectiveness of the different regulatory institutions implemented with help of the smart card machines. In the given context, groundwater quota is more effective in curbing farmers’ groundwater use than the tiered groundwater pricing. The study shows that the usefulness of smart card machines depends on their embedding in the societal context and related regulatory institutions.  相似文献
