11.3.3 Spatial vs temporal scale of community resilience
Resilience can be considered as a dynamic quantity that changes over time
and across space. It can be applied to engineering, economic, social and
institutional infrastructure, and it can be used for various geographic scales.
The fi rst step to quantify
R
is to defi ne the
spatial scale
(e.g. building, struc-
ture, community, city, region) of the problem of interest (Fig. 11.2). It is
important to mention that the entire recovery process is affected by the
spatial scale
of the disaster. Huge disasters will need a longer recovery
process. The
spatial scale
will also be used to defi ne the performance mea-
sures for the global functionality of the system. The second step is to defi ne
