| Zusammenfassung |
The essential services that support urban living are complex and
interdependent, and their disruption in disasters directly affects society.
Yet there are few empirical studies to inform our understanding of the
vulnerabilities and resilience of complex infrastructure systems in
disasters.
This research takes a systems thinking approach to explore the dynamic
behaviour of a network of essential services, in the presence and absence of
volcanic ashfall hazards in Montserrat, West Indies. Adopting a case study
methodology and qualitative methods to gather empirical data, we centre the
study on the healthcare system and its interconnected network of essential
services. We identify different types of relationship between sectors and
develop a new interdependence classification system for analysis.
Relationships are further categorised by hazard conditions, for use in
extensive risk contexts.
During heightened volcanic activity, relationships between systems transform
in both number and type: connections increase across the network by 41%,
and adapt to increase cooperation and information sharing. Interconnections
add capacities to the network, increasing the resilience of prioritised
sectors. This in-depth and context-specific approach provides a new
methodology for studying the dynamics of infrastructure interdependence in an
extensive risk context, and can be adapted for use in other hazard contexts. |
