Panel II: Maryland in a Changing World
Infrastructure
Matthias Ruth, Director, Center for Integrative
Environmental Research
Abstract
Infrastructure systems are often lumpy, their development and
maintenance are costly, and once put in place, they are hard to change. This
holds for the grey structures, such as roads, water and sewer systems,
or energy generation and supply infrastructure. Additional complexities
for development and maintenance arise from the interdependence of these
systems, such as those between energy and water. For example,
electricity generation often requires adequate fresh water supply for
cooling purposes. During periods of low stream flow, electricity
generation may be impaired. Those may also be the periods in
which demand for power is largest – for example, for cooling
and air conditioning, or for water pumping and aeration in water treatment
plants. Other interdependencies are with “green infrastructures”,
for example when urban forestry helps reduce summer time energy demand
but increases likelihood of power interruption during ice and snow
events. The “soft infrastructures” – the institutions
that govern the other systems as if they were largely separable – are
equally interdependent and often hard to change.
This presentation addresses current and likely future challenges
to, and opportunities for infrastructure development, with special
focus on the interdependencies of grey, green and soft infrastructure. Since
changing infrastructures is likely to be slow and expensive, anticipation
of future technological, demographic, economic, and environmental conditions
becomes key to effective infrastructure planning and management. The
case is made that, since these future conditions are highly uncertain
and often full of surprise, a new mind set is necessary for planning
and management, that distinguishes itself from the mechanistic, cause-effect
approaches that characterize infrastructure management today.
