ABSTRACT
There are many pressures on
urban water systems in today’s highly dynamic world. These include the diverse
impacts that are summarized under the term “Global Change”. At the same time,
high demands on water utilities to act sustainably do exist. For this purpose,
the collaborative project “Sustainability Controlling for Urban Water Systems”
(NaCoSi) introduces an innovative approach with which sustainability risks can
be identified and controlled. The sustainability controlling is based on common
process-oriented management systems. The starting point is a system of
sustainability objectives, which were developed together with practice partners
from the German water sector. A method for multidimensional risk identification
is introduced to identify sustainability risks. Complex networks of
cause-effect relationships are disaggregated into unbranched linear causal
chains, which are managed as
records in a risk database. The subsequent analysis of the risk database allows
the examination of cross-linked risks. Severe risk factors, vulnerable
processes and sustainability objectives can thereby be identified and
subsequently analyzed. The sustainability controlling was successfully tested
and improved by an iterative process of case studies in cooperation with
practice partners. The results of the case studies demonstrate the benefit of the
project’s interdisciplinary approach and the applicability of the
sustainability controlling.
