The cities of Narayanganj in Bangladesh and Bishkek in Kyrghyzstan were selected for the case-studies because they represent two of the most common urban groundwater development environments (Table 1 and socioeconomic situations where water quality deterioration could have serious economic consequences (Morris et al, 1994)). The hydrogeological setting of Narayanganj (deep fluvio-deltaic multi-aquifer)and of Bishkek (on a piedmont/alluvial outwash plain aquifer adjacent to a high mountain region) are both frequently encountered, especially in the South, Central and East Asian regions.
The results of the study can therefore be generalised to numerous other cities of similar type. The cities contrast with each other socio-economically, as Bangladesh is an industrialising developing world economy, while Kyrghyzstan is an excommand economy in transition. There are thus opportunities for lessons to be learnt in the evolution of practical sustainable
development policies in different socioeconomic settings.
