The Monstrous
‘Western Invention’
Landmine
Kills Innocents &
Remain Hard to
Detect.

A metal detector is
the most common
device used for
searching landmines,
which litter the
soil in
approximately 90
countries. Many of
these countries are
located in the
tropics where
intensively
weathered soils are
prevalent.
These tropical
soils have certain
properties that can
limit the
performance of metal
detectors due to
soil magnetic
susceptibility. This
problem is enhanced
by the spread of
minimum-metal mines,
according to
ScienceDaily.
Magnetic properties
of soils are caused
by ferrimagnetic
minerals, such as
magnetite and
maghemite. The
negative effects can
result in a
reduction of
detector sensitivity
or cause false
alarms.
To overcome these
problems, the metal
detectors have been
continuously
re-hauled over the
years but only now
has taken the
geoscientific
research of soil
into account. The
knowledge of soil
magnetic properties
may allow detectors
to be adapted to
meet the local
conditions.
Geoscientists at the
Leibniz Institute
for Applied
Geosciences and the
Federal Institute
for Geosciences and
Natural Resources in
Hannover, Germany
conducted a study on
the magnetic
susceptibility of
tropical soils using
the soil archive of
the Federal Agency.
The magnetic
susceptibility of
more than 500 soil
samples from the
entire tropical belt
was analyzed with
the goal of
classifying their
impact on landmine
detection.
The study revealed
that the problem of
soil influence can
occur quite
frequently. More
than one-third of
the measured soil
samples may generate
severe or very
severe limitations
when using metal
detectors.
Soils were grouped
according to their
parent rocks. On
average
susceptibility of
soils with basaltic
origin were higher
than those of other
origin. However, the
variability within
the different groups
is high.
This provides
evidence that
besides origin,
additional
influences on soil
susceptibility such
as soil development
are likely to exist.
Basic
Landmine Facts
In 2005 the Landmine
Monitor identified
at least 84
countries and eight
areas contaminated
with landmines and
unexploded ordnance
(UXO); 54 of the
affected countries
are States Parties
to the Ottawa
Treaty.
As of 2005, more
than 200,000 square
kilometers are
suspected to be
contaminated by
landmines and UXO.
Since May 2004 three
governments have
been confirmed to
use antipersonnel
landmines: Myanmar
(Burma), Nepal, and
Russia. Nepal has
since stopped by
mid-2006.
The use of
antipersonnel mines
and mine-like
improvised explosive
devices (IEDs) by
Non-State Armed
Groups (NSAGs) have
been reported in six
States Parties to
the Ottawa Treaty
(Burundi, Colombia,
Iraq, Philippines,
Turkey and Uganda)
and in seven
non-States Parties
(Myanmar, Georgia,
India, Nepal,
Pakistan, Somalia
and Russia).
There are 13
countries that
continue to produce
antipersonnel
landmines: Myanmar,
China, Cuba, India,
Iran, North Korea,
South Korea, Nepal,
Pakistan, Russia,
Singapore, United
States, and Vietnam.
Since the mid-1990s
there has been a de
facto ban on the
transfer or export
of antipersonnel
mines. There have
been no documented
state-to-state
transfers since
then. It is believed
that the trade of
antipersonnel mines
has dwindled to a
very low level of
illicit trafficking
and unacknowledged
trade.
Prior
to the Ottawa
Treaty, 131 states
possessed
stockpiles,
estimated at over
260 million
antipersonnel mines.
The Landmine Monitor
now estimates that
54 countries have
stockpiles, totaling
180 million
antipersonnel mines.
