1.

the
more
we
know,
the
more
we
lose….
2.
DRR

necessary,

limited.
3.

a

4.
But
not
only
a
quesLon
of
informaLon
and
knowledge
as
such….
THE
challenges….

3. 1. The more we know, the more we lose?
Assessments on disaster frequencies and losses
look paradoxical (White et al. 2001): « the more we know, the more we lose…. »
Papers on resilience in peer-review journals.
(Kuhlicke, 2011)
A. The more we know
B. The more we lose???
Yet, C….
How to reduce losses even more?

Where
do
we
find
the

areas?

8. Insights
• How
to
reduce
more
informaLon
fragmentaLon
on
DRR
between
insLtuLons
and
stakeholders?
• How
prevenLng
more
disasters
with
local
stakeholders?
• “Increasing
the
quality
and
coverage
of
data
is
seen
as
central
to
operaLonalising
DRR
policies,
but
success
does
not,
however,
hinge
simply
on
the
provision
of
more
accurate
and
comprehensive
data”
