Regulation and Private Participation in the Water and Sanitation Sector (TAC Background Papers No.1)

Judith A. Rees   Th. 808

Private sector participation is widely perceived to be the solution to the failure of many publicly owned and managed water utilities to operate efficiently and make the investments required to meet community needs. However, there are no guarantees that privatisation will actually yield the desired performence improvements. Simply converting a public sector monopoly into a private one provides no competitive incentives for the utility to operate efficiently, make appropriate investments or respond to consumer demands. Likewise, privatisation per se need do little to improve sector performance if governments are unwiling or unable to tackle such underlying problems as over-manning, uneconomic water pricing policies, financing the provision of public and merit goods, and restricting over-intrusive political intervention.
 
Given the characteristics of the water and sanitation sector it is inevitable that some form of continued public regulation of the private companies will be necessary. The regulatory burden can be reduced by adopting a competitive form of privatisation, choosing a more competitive sector structure and devising an appropriate regulatory regime. However, it has to be recognised that there will be a trade-off between making a venture attractive to private firms and introducing a notionally ’ideal’ regulatory system. Regulation in practice is a much about creating the conditions under which private firms can operate effectively and efficiently as it is about protecting specific customer and public interests.

 

Water as a Social and Economic Good: How to Put the Principle into Practice (TAC Background Papers No.2)

Peter Rogers, Ramesh Bhatia & Annette Huber   Th. 802

Agenda 21 and  the Dublin Principles put the concept of water as an economic good on the global agenda, and they have received wide acceptance by the world’s water professionals. However, there is substansial confusion about the exact meaning of some of the articulated principles. In particular, it is not clear to many non-economists what is implied by the statement that water is an ”economic good“ or an ”economic and social good“. This paper addresses this lack of understanding by formulating the concept of water as an economic good and explaining, in practical terms, the economic tools that can be used to effect the environmentally, socially, and economically efficient use of water.
 
The potential role of economic tools in providing socially acceptable public decisions is not widely appreciated, particularly in many highly regulated situations. Furthermore, this paper suggests, contrary to the public perception, that with the improvement of the use of economic tools, the role for government regulation in managing water as an economic good is increased, not decreased.
 
The paper is divided into three sections following this introduction: Section I presents the general principles and methodologies for estimating costs and values in the water sector. In section II, some illustrative estimates of costs and values in urban, industrial, and agricultural sectors are presented based on available adta. Section III provides summary of results and conclusions.
 

”...Integrated Water Resources Management (IWRM) and Water Efficiency Plans by 2005“ Why, What and How? (TAC Background Papers No.10)

Torkil Jonch-Clausen   Th. 1.237

This document has been written to support reform processes in water resources management and development, incipient or well underway, and to guide the development towards Integrated Water Resources Management (IWRM) as proposed in the Plan of Implementation of the World Summit for Sustainable Development (WSSD) in Johannesburg in 2002. Article 26 of this states that countries should ”Develop IWRM and water effiency plans by 2005, with support to developing countries....“. This guidance document discusses what these plans are all about under the overall umbrella of IWRM. Focus is on IWRM. The ”water efficiency plan“ is considered as an important component of IWRM, and hence as an integral part of the IWRM plan. As discussed in the document IWRM is a cyclic and long term ”process“. Hence, the ”IWRM plan“ can be seen as a milestone in this process, where the status of the process is documented.

Exploring the Links Between International Business and Poverty Reduction: A Case Study of Unilever in Indonesia

Jason Clay   Th. 1.325

Foreign direct investment is recognised to be important for economic development, in  terms of wealth creation, employment, skills development, and technology transfer. But there is an on-going debate about the extent to which these contributions translate into real benefits for people living in poverty.
 
In an attempt to evaluate the impacts of international business on people living in poverty, two organisations with very different aims and perspectives – Unilever (a major company operating in some of the poorest countries in the world) and Oxfam (an international development and humanitarian organisation) – collaborated on an ambitious research project. The research considered the impacts of Unilever Indonesia across the entire business value chain, from producers and suppliers, through the company’s core business operations, to its distributors, retailers, and consumers. This report presents the findings of the research. It is a contribution to the debates among the wider business community, governments, civil-society organisations, and academics who seek to understand how the wealth, employment, and products that a large compay creates could bring increased benefits to people living in poverty.

Endemic Arsenicosis: A Clinical Diagnostic Manual with Photo Illustrations (Sino-English bilingual version)

Sun Guifan, dkk    Th. 870

This manual has been prepared to serve as a reference resource for medical officers, health workers and programme officers to use for clinical diagnosis of arsenicosis caused by chronic arsenic poisoning from drinking water or contaminated food due to coal burning. It also is intended for use in the training of medical professionals and health workers.
 
This manual is the first publication on clinical diagnosis of skin lesions of arsenicosis. Medical professionals have yet to establish a clear case definition of arsenicosis. However, a group of arsenicosis experts in the People’s Republic of China developed guidelines for clinical identification based on their decades of field experiences dealing with chronic arsenic poisoning. China’s Ministry of Health recently approved those guidelines.
 
Adopting the Chinese classification, this manual presents symptoms of skin lesions of arsenicosis, along with photos to illustrate its stage-by stage manifestation, that are based on cases in affected areas in China. Some variation of symptoms between areas does occur. For instance, ”black foot disease“ is associated with the consumption of drinking water containing high levels of arsenic and humic substances having fluorescent matter but was found only in Taiwan province in the 1950s. So far, it has not been identified in any other affected area in China (This manual does not include symptoms of black foot disease). Generally, however, skin lesions of arsenicosis in the forms of hyperkeratosis, hyper-pigmentation and hypo-pigmentation commonly are diagnosed in patients suffering from chronic arsenic poisoning due to the consumption of water, food or inhaling air containing high levels of arsenic. It is these symptoms taht are the focus of this manual.
 
For readers’ convenience, this manual has been published in separate English and Chinese versions.

Predicting The Global Extent of Arsenic Pollution of Groundwater and Its Potential Impact on Human Health

Peter Ravenscroft   Th. 873

Natural arsenic pollution of groundwater and surface water affects more than 140 million people in at least 70 countries worldwide. In half the countries where arsenic pollution is now known, it was discovered within the last ten years, and it is almost certain that it will be found in many more. The objective of this study is to predict the other countries and regions in which there is a significant risk of finding arsenic pollution.
 
By examining known arsenic occurences, their geochemistry, and their climatic and geological associations, it has proved possible to develop a set of predictive rules that have been embodied in a GIS model. This model not only predicts the locations where there is a risk that groundwater is polluted by arsenic, it also estimates the population of the ’at risk’ regions, and hence provides a basis for predicting the size of the population which may be exposed to drinking arsenic above the WHO guideline value and/or local standards. The GIS model does not predict all known forms of natural arsenic pollution, but based on known occurrences, is expected to predict more than 90% of them.
 
The GIS model has been applied to the whole world, and this report provides maps of the at risk areas and listings of the at-risk population in each country. The model successfully predicts the vast majority of the major known cases of pollution. The model predicts a risk of arsenic pollution in 54 countries where pollution is known to occur, and also in a further 53 countries where it is not known. Nine countries, with large at-risk populations but no reported cases of pollution, have been selected for more detailed mapping. These countries were chosen to represent a range of conditions and include four in Asia (Indonesia, the Philippines, Iraq, and Uzbekistan), two in South America (Colombia and Venezuela) and three in Africa (Ethiopia, Sudan and Marocco).
 
Where a risk of arsenic pollution is predicted, relevant courses of action are recommended. In countries where arsenic is a familiar problem, it may be sufficient to provide guidance for additional surveys. Where arsenic pollution is predicted but not known, a second tier of desk study is recommended to evaluate the model predictions in the light of national data sets and, provisionally, to identify areas, personnel and testing protocols for field surveys.
