Urban Ecology and Transformation of Technical Infrastructure

There is a need to rethink technical infrastructure for energy and water provision and for handling sewage and solic waste due to environmental problems related to the current large-scale systems. From the authors point of view this includes a shift towards combining bottom-up strategies with top-down strategies instead of seeing such strategies as incompatible. Today´s planning practice and the momentum of the established systems require new forums for stratgic debates if urban ecology is to be included in future network management. A methodolgy is presented for structuring a debate on future sustainable systems, which includes new actors with very different viewpoints on network management in the debate on the transformation process.
