SYSTEMIC RISKS AND EMERGING
FUTURE CHALLENGES
Theory is our roadmap. It helps
make complex situations clear.
Towards a renewal of theory for
the 21st century: we cannot
afford to allow theory
to lag behind events
and developments.
Systematic risk refers to the possible
breakdown of an entire system rather than
merely the failure of some of its parts.
Existential risk refers to the likelihood of a
disaster that threatens the existence of all or
a significant part of the human race.
The system is... Example of catalytic disaster
Substituted
Economic catastrophe after an enormous
natural or anthropogenic event
Threshold of economic sustainability
Redirected Indian Ocean tsunami, 2004 (?)
Threshold of political and public tolerance
Static Earthquakes: Sichuan 2008, Nepal 2015
Threshold of sustained political and public attention
In decline No significant major events

Intersectionality - borrowed (with
apologies) from studies of race and
culture
Intersection of:
• forms of disaster causality
• different kinds of disaster and crisis
• disaster and its context
• disaster and social circumstances
Where are our standards and moral principles?
• human rights - in retreat
• democracy - threatened by authoritarianism
• identity - acquires new meaning
• sovereignty - in a globalised world, needs to be
redefined
• mobility - no longer containable
• welfare - undefined, undefinable?
• hegemony (proxy wars) - destructive free-for-all
• legality - under threat by anomie (nihilism)

Anomie (Durkheim 1893) is a condition

a breakdown of standards
and values or from
a lack of purpose
or ideals.

CONCLUSIONS
Conclusions:-
• participatory democracy is the key to
disaster risk reduction and it must be
founded on human rights
• inequality and inequity often result from
poor human rights and may be diagnostic
of inability to act
• the foundation of rights is shifting as the
world goes rapidly through
momentous changes
Foresight, planning and communication are
the keys to success in disaster reduction:-
• foresight must examine future outcomes
with creativity and intelligence
• planning must follow quality standards
(which have yet to be established)
• communication must be clear, consistent
and trustworthy
LIFE SAVING
RESPONSE
• search and rescue
• crisis evacuation
• medical surge capacity
• intensive care capacity
• epidemiology and
disease prevention
DAMAGE
LIMITATION
• infrastructure
protection
• impact reduction
measures
• bracing of damaged
structures
LAUNCHING
RECOVERY
• route clearance
• infrastructure repair
• debris management
