Rietvlei Dust Storm -

Dust
storms
from
Rietvlei
during
the
dry
summer
months
is a
frequent
occurrence.
This
usually
leads
to
numerous
complaints
from
affected
residents
and
calls
on
the
City
Council
to
take
urgent
steps
to
prevent
dust
blowing
from
the
vlei.
Summer
dust
storms
are
a
natural
occurrence
on
dry
vleis
in
the
winter
rainfall
area.
The
vleis
dry
up
during
the
summer
months
and
strong
southeasterly
winds
blow
clouds
of
dust
from
the
exposed
areas
of
the
vlei.
This
is
particularly
prevalent
on
the
west
coast,
from
Rietvlei
northwards
to
the
Orange
River
mouth.
Occasionally
this
is
caused
by
man's
activities
- in
some
areas
farmers
used
to
plough
dry
wetlands
and
plant
crops
-
but
this
is
not
so
common
these
days.
The
dust
storm
is
nature's
way
of
redistributing
the
rich
sediments
that
accumulate
during
the
wet
months
onto
the
adjoining
veld.
Most
of
the
westcoast
veld,
particularly
closer
to
the
sea,
is
poor
in
nutrients.
Dust
blowing
from
wetlands
serve
as a
natural
fertiliser;
it
delivers
a
considerable
nutrient
load
to
adjacent
soils.
Dust
blowing
from
Rietvlei
is
not
a
new
occurrence,
there
is
not
much
about
dust
storms
in
historical
records
of
Rietvlei,
but
one
can
safely
assume
that
it
has
been
a
regular
occurrence
for
hundreds
of
years.
In
the
past
it
was
not
regarded
as a
nuisance
to
people,
only
since
the
development
of
Table
View
has
it
become
a
problem.
There
is
nothing
much
the
City
Council
can
do
to
prevent
the
dust
blowing.
Water
is
being
fed
into
the
dry
areas
to
dampen
the
surface,
and
this
does
help
a
bit.
In
the
past
when
water
trucks
were
used
to
spray
the
area,
the
situation
actually
became
worse.
The
trucks
cracked
the
surface
crust
and
more
dust
than
ever
before
came
from
those
areas.
