International and Intra-national Exploration
Publication Year: 2010
Published by: NUS Press Pte Ltd
This monograph is the result of the collective efforts of four full time researchers of the Institute of Water Policy (IWP). It is motivated by the fact that water is central to economic and human development and its availability and access ought to be measured and monitored — an issue that has become even more crucial in the context of the Millennium Development Goals. ...
1. Introduction and Motivation
The Index of Drinking Water Adequacy (IDWA), as its name implies, is a monitoring tool devised to assess and benchmark countries’ performance in providing adequate drinking water to their citizens. IDWA is inspired by the lack of an adequate indicator for monitoring access to drinking water of adequate quantity and quality. ...
2. Drinking Water Adequacy Differentials in Asia
An Index of Drinking Water Adequacy (referred to as IDWA-I in this paper) was first proposed in 2007 for 23 member countries of the Asian Development Bank (ADB), and formed part of the Asian Water and Development Outlook (AWDO), 2007 brought out by the ADB. IDWA-I was obtained by averaging 5 separate component indicators...
3. Global Situation on Drinking Water Adequacy
This paper provides estimates of the Index of Drinking Water Adequacy (IDWA) for 144 countries for the most recent year for which component indicators are available. Inter-correlations between IDWA and selected human development and governance indicators are explored and implications noted. ...
4. Among the Indian States
IDWA was first introduced in the Asian Water and Development Outlook, 2007, a report issued by the Asian Development Bank. The computation of the index (more recently christened IDWA-I) calls for data on 5 different parameters: resources, capacity, access, quality and use. For 28 Indian states, we could manage...
5. Across the Chinese Provinces
In this paper, we explore the measurement of drinking water adequacy in the provinces of China, following the earlier investigations pertaining to Asian nations and Indian states. Inter- provincial differences in IDWA in China are no less pronounced than in India, a fact that underscores the importance of working for narrowing the differentials. ...
6. Data on Drinking Water Access: The Case of Vietnam
The Index of Drinking Water Adequacy (IDWA) is based on averaging five component indexes of which one key component refers to “access”. Access data are used widely in the Millennium Development Goals (MDGs) and are based on the estimates reported in the database from the Joint Monitoring Program for Water Supply and Sanitation (JMP). ...
7. Concluding Notes
The “concluding notes” are explicitly and implicitly suggested by the papers in this monograph. They refer to the need for data monitoring and possible and desirable fine-tuning of the MDG. At the end of this short note, two key messages are placed prominently to draw the attention of all concerned. ...
