Buried infrastructure in shrinking cities
This paper deals with the impact of shrinking cities on buried infrastructure. Demographic trends indicate a long-term decline in population and employment all over Europe, particularly in rural areas and smaller towns. In larger cities, some quarters will be affected as well. Different spatial patterns of urban shrinkage are presented.
Ultimately, the diminishing population leads to perforated urban areas. There are little chances for densification around centres and along axes of infrastructure. New building activities will continue on a smaller scale than today.
Due to the thinning-out and expansion of the urban area, the demand for infrastructural services will change in time and space. Parts of buried infrastructures will become over-sized, a few of them even obsolete. However, most of them are still needed in the context of the distribution network. This process of shrinking demand for infrastructural services is accentuated by the decline of demand per capita, due to more economical and efficient use of water and energy in accordance with the objectives of sustainability.
Consequently, the specific costs for the provision of infrastructural services increase. Another driving factor for increasing costs of infrastructural services is the need for infrastructure rehabilitation which, on the other hand, provides an opportunity for down-sizing the system and adapting it in a sustainable way to the emerging pattern of demand. |
