This
event
will
be
offered
online.
Societies
have
increasingly
influenced
the
frequency
and
severity
of
hydrological
drought
over
the
past
centuries
by:
i)
building
dams
and
reservoirs
to
secure
water
supply;
ii)
diverting
water
flows
to
supply
cities,
industries
and
agriculture;
and
iii)
changing
river
basin
characteristics
through
deforestation,
urbanization
and
drainage
of
wetlands.
While
societies
influence
hydrological
droughts,
drought
occurrences
(and
risks)
influence
societies.
Adaptive
responses
include
migration
fromdrought-affected
areas
or
changes
in
water
allocation
and
governance.
In
this
talk,
I
present
case
studies,
global
analyses
and
models
to
show
how
these
sociohydrological
feedbacks
can
generate
legacy
risks
or
social
inequalities
and
thus
challenge
the
development
of
sustainable
policies
of
disaster
risk
reduction
and
water
management.
