Aspects of Urban Water and Sanitation in the Context of Rapid Urbanization in Developing Asia
Pernia, Ernesto M; Alabastro, Stella LF | September 1997
Abstract
The problem of access to urban water and sanitation services is be-coming all too obvious in developing Asia, especially in the less developed economies. Rapid urbanization in the coming years implies that the prob¬lem can only worsen under a "business-as-usual" sort of policy regime. Clearly, a redoubling of efforts is called for to deal with the situation. This paper attempts to examine some relevant key issues and identify ways of addressing them.
Because access to water and sanitation services is income-elastic, particularly at lower income ranges, rapid and sustained economic growth will be important. Also significantly instrumental will be reduction in popu-lation pressures from a natural increase in and migration to large cities. This is so because of negative congestion effects, and there appears to be no clear economies of scale in the provision of water and sanitation services; on the contrary, there are indications that such services can be supplied less expen-sively in smaller cities and towns.
There is ample scope for private sector provision and/or private fi-nancing of water via appropriate user fees; some cross subsidization scheme can be adopted to deal with equity issues. In the case of sanitation, given the typical public-goods problem, direct government intervention will be needed especially in low-income communities. Government decentralization and devolution appears beneficial for the whole issue of urban infrastruc¬ture and basic services. Local governments should therefore be accorded the necessary institutional and financial support to adequately perform this function. Finally, assistance to private enterprises could be sought from development finance institutions in the form of affordable loans that may be required during the first few years of operation.

Urban Innovations and Best Practices: Retrofitting Sustainable Urban Development Practices: Urban Public Transport
Asian Development Bank (Asian Development Bank, 2010-11-15)Fast-growing cities in developing countries are often plagued by the twin problems of congestion and inadequate public transport systems. In some cases, a Bus Rapid Transit (BRT) system can help to bridge the gap. By using dedicated bus lanes to develop a moderately rapid mass transit system, a BRT system generally requires lower infrastructure investment as compared with a subway or light rail ...Fast-growing cities in developing countries are often plagued by the twin problems of congestion and inadequate public transport systems.

Urban Innovations and Best Practices: Urban Development Policy of India (Part 2) - Corridor Densification by Floor Space Index-linked Land Use Control and Infrastructure Financing Mechanism
Asian Development Bank (Asian Development Bank, 2010-04-15)Cities in India have been the “engine of economic growth.” But realizing future economic growth hinges on whether or not Indian cities can be made more efficient, livable, inclusive, and competitive. To achieve this, it is essential to strengthen urban governance and management through greater decentralization and enhanced accountability, and establish appropriate delivery mechanisms and regulatory ...Cities in India have been the “engine of economic growth.” But realizing future economic growth hinges on whether or not Indian cities can be made more efficient, livable, inclusive, and competitive.

Urban Innovations and Best Practices: Urban Water Supply: Case Study of Public-Private Partnerships (PPPs) in Maanshan
Asian Development Bank (Asian Development Bank, 2010-11-15)Of the 660 large cities in the PRC, more than 400 are expected to face chronic water shortages. This is exacerbated by the (i) uneven distribution of water resources between the north and south regions of the PRC, (ii) industrial pollution contaminating many water sources, (iii) over-extraction, and (iv) relatively inefficient use of available water resources. The public urban water and sewerage ...Of the 660 large cities in the PRC, more than 400 are expected to face chronic water shortages.
