This book was released on 2011-06-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: In South Africa, water is a relative scarce resource that is distributed unevenly geographically and saisonally as well as socially. The Middle Olifants sub-basin of South Africa was chosen as study area, because it is characterized as a very water scarce region -it is counted as the third most stressed basin in South Africa -with a poor and predominantly rural population. Households in former-homeland areas are still disadvantaged and lack access to su?cient and reliable water services. Current water use in the basin leads to overuse of the resource at the expense of domestic and environmental water needs. For an e?ective water management that is able to address the South African policy objectives of e?ciency in water use, equity in access and bene?ts as well as long-term sustainability, economic valuation of the di?erent water uses is required. In order to assist policy-makers in reaching these goals, this study contributes to the existing knowledge by providing information on the economic value of water in domestic uses. For this purpose, two separate choice experiments were designed to detect preferences and ‘Willingness to pay’ for di?erent water service levels and water sources. Results of a household survey of 475 households provide a clear picture of the di?erent water sources and service levels received by households in the Middle Olifants. Sampled households using basic water sources such as Public taps, Yard connections or Boreholes consume on aver¬age only 18.68 liter per person per day, while households with private taps inside their houses consume 78 liter per person per day. To analyze preferences for water services at the house¬hold level and to detect households’ ‘Willingness to pay’ for improved service levels, choice experiments were carried out in four villages and one town. Data analysis indicates the pres¬ence of preference heterogeneity and, hence, a latent class model was applied, readily dividing households into homogeneous groups according to their preferences. Several distinct classes of households could be found di?ering signi?cantly in terms of socio-economic characteristics, particularly household income, current water consumption and service levels as well as atti¬tudes towards pricing of water and satisfaction with current water service levels. ‘Willingness to pay’-estimates of single water service characteristics of all groups indicate that households are willing to pay higher prices for a better and more reliable water provision. But the amount of money households are willing to spend di?ers among groups. Price sensitivity was found to be strongly linked to income. With increasing income, price sensitivity of households decreases. This information is helpful for policy-makers to enable the design of water services in the Mid¬dle Olifants according to preferences of local households. The increase in ‘Willingness to pay’ with increasing income shows that subsidies either as income subsidies or lower water tari?s may be useful tools to allow low-income households to pay water bills.

Book excerpt: Using household survey data, this study investigates preferences for domestic water services in the Middle Olifants sub-basin of South Africa. Water is a relatively scarce resource in South Africa that is distributed unevenly both geographically and seasonally as well as socio-politically. For a water management addressing the policy objectives of efficiency in use, equity in access and benefits and long-term sustainability, economic valuation of the different water uses is required. In order to detect households' preferences, a choice experiment of the various water services was conducted. Results suggested the presence of preference heterogeneity and therefore, a latent class model was applied, dividing households into homogeneous groups according to their preferences. Four distinct groups of households could be identified which differ significantly in terms of their socio-economic characteristics, their attitudes toward pricing of water and their satisfaction with current water service levels. Willingness to pay (WTP) estimates of different water service characteristics in all groups indicate that households are willing to pay higher prices for a better and more reliable water services provision. But the amount households are willing to pay differs among the groups. This information is helpful for policy-makers to enable the design of water services in the Middle Olifants according to preferences of local households. Besides, WTP estimation can provide a basis for setting water tariffs.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using data gathered from the National Treasury of South Africa, we examine the structure of water supply costs and tariffs of Water Service Authorities (WSAs) in the Middle Olifants sub-basin of South Africa. Using the translog cost function method, the marginal cost of water supply and economies of scale are estimated. Comparison of tariffs and marginal costs show that the estimated marginal cost is higher than the actual tariff paid by consumers. This implies that WSAs in the Middle Olifants are not charging enough to recover the costs of the water services. Thus, among other things, pricing of water at its marginal cost would partly assist in solving the cost recovery problem. Raised tariffs would in turn contribute to improved efficiency of water use. As evidenced by estimation results of returns to scale (greater than one), merger of WSAs would be economically advantageous. Hence, reversing the process of transferring water services' authority to 'local' municipality level and thus up-scaling WSAs into the 'district' municipality level is an important policy option for improving water services efficiency in the Middle Olifants sub-basin of South Africa.

This book was released on 2007-01-01 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a valuable new tool for water management water resource accounting which significantly advances the economic analysis of water. Water resource accounts integrate detailed information about water supply and use with national income accounts to show the economic use of water, costs and tariffs paid, and the economic value of water for different economic uses. Based on the UN s handbook for environmental accounting, this book describes the implementation and policy application of water accounts in three African countries Botswana, Namibia and South Africa and discusses how they have been used by water managers. The book compares water use across the three countries, explaining the differences in water resources and water policy. In addition to the comprehensive outline of physical and monetary water accounts for each country, the authors provide an extensive discussion of water valuation as well as addressing a number of issues of regional importance, including water accounting for an international river basin and the impact of trade on each country s water use. By demonstrating the usefulness of water resource accounts, this book makes a major contribution to the literature on water economics and management, sustainable development, and to the development of environmental accounting in general. The Economics of Water Management in Southern Africa will appeal to a wide readership including: environmental and development economists NGOs concerned with sustainable development environmental advocacy groups professionals (economists and environmentalists) working in Africa on water and sustainable development issues water professionals national accounts experts and statisticians.

This book was released on 2005 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water pricing (in its broad sense, which means water tariff setting and subsidies), water services sectors organisations and costs generated by infrastructures are key factor for enhancing livelihood in developing countries. Some key objectives of any water pricing policies can be identified : cost-recovery, economise efficiency, economic affordability, equity, justified need, no perverse incentive, low administrative costs. This study explores in what extent water pricing policies implemented in the Olifants River Basin, South African respond to these various objectives. This study is also interested in costs generated by domestic water networks in the same area. The present study introduces the South African context of domestic water services, strongly marked by a decentralisation willing. It also presents the Olifants River Basin in a physical and socio-economic point review. To plant the problem, it also develops water pricing policies related economic issues in developing countries in general, and in South Africa in particular. In the third place, it presents the methodology adopted to answer the research questions. At least, results in term of water sector organisation, of presentation and evaluation of the water pricing policies implemented in the study area and of the conditions of networks in the same area are presented.

This book was released on 2007 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were estimated for each sector and the economic cost of failing to provide water was predicted. For the future scenarios, the impact of infrastructure development and water conservation measures were assessed. The study illustrates how a relatively simple model can provide useful insight for resource planning and management.

Available in PDF, EPUB and Kindle. Book excerpt: The deterioration of water quality threatens the functioning of ecosystems and the sustainability of socioeconomic growth and development more especially for a water-stressed country like South Africa (SA). The Olifants river basin, which is one of the nine water management areas in SA, faces serious water scarcity, with declining surface and groundwater quality due to pollution from mining activities, irrigation agriculture, and industrial waste disposal. This has led to great competition for water among different economic sectors and between upstream and downstream users. As a result, the government has implemented a series of pollution control measures with the view to mitigating pollution and water shortage in the basin. This study developed and used a regional, environmental, computable general equilibrium (CGE) model to assess the environmental, economic, and social impacts of protecting the basin"Ë−s water resources. To calibrate the model, the study also constructed an environmental social accounting matrix (ESAM) using the framework of an environmentally extended SAM. Results of the environmental and economic impacts of taxing water pollution suggest that internalising the negative externality of water pollution in the Olifants river basin will effectively reduce pollution discharge (i.e., achieve its environmental goals). This, however, comes at some costs to the regional economy of the basin. The economic burden of the tax happens to be fairly small though, due to the small relative share of the water pollution supply and abatement costs in total production costs. Furthermore, recycling the tax revenue through income transfers to households or a subsidy to pollution abatement mitigates the adverse economic impacts. Results of the distributional impacts of taxing water pollution in the basin indicate that the water pollution tax is progressive (inequity and poverty-reducing) on the income side as the poorest and vulnerable derive lower shares of their income from capital, which bears the biggest burden of the tax. On the expenditure side, however, the tax is regressive (inequity and poverty increasing), due to the higher share of pollution-intensive goods in poor households"Ë−expenditure. The net effect of the tax is, however, not pro-poor. Recycling the tax revenue through a subsidy to pollution abatement sectors reduces the adverse effect of the tax on household welfare whereas uniform direct lump-sum transfers to households"Ë−income results in a progressive outcome. This study has demonstrated the importance of using an integrated framework that allows non-linear substitution possibilities and endogenous price determination to account for both the direct and indirect costs of water quality management policies. The findings should, however, be viewed with caution due to some limitations inherent in basic assumptions of this study. Firstly, demand for pollution abatement services by production sectors, is specified in a simple way using exogenously determined clean-up rates and the assumption that unit costs of pollution abatement are fixed. Secondly, this study did not account for the economic benefits from water quality improvements as well as from technological advancements that lead to reduced pollution intensities.
