The Sahel Region is at risk of environmental damage
called desertification. This is the process whereby
the land turns to desert.

of these
Strategies?
1.
‘Magic Stones’ aka Low Stone Walls
2.
Planting trees – e.g. Acacia Gum Trees
Others…..
3. National Parks and Reserves
4. Water and Soil Management
One management strategy used to reduce the risk of
desertification is the method called
‘Magic Stones’
.
Lines of low stone walls have been built by local
communities along contour lines using stones from
the surrounding area. When the rain comes, the
walls trap the water, also preventing the soil from
being washed away. Moisture is therefore held in
the soil.
This management strategy is very
important
. Not only has it helped to
reduce
desertification by preventing soil erosion
, but it is
also very
sustainable
as it
uses appropriate
technology
. In areas of the
Sahel
where it has been
implemented, farmers have been able to increase
their crop yields by up to 50%.
This means that
there is enough food to feed the population in the
region,
therefore
preventing
food insecurity
and
famine from occurring.
A second management strategy used in areas of the
Sahel
which is also very important,
is the
planting of
trees
. In particular, in Senegal, they have planted
Acacia Gum trees
.
Planting the trees reverses
desertification by preventing soil erosion
. The tree
roots binds the soil together and the leaves and
branches provide shade for plants and animals. The
trees also provide an income for local people,
nutrients for other plants and crops to grow, as well
as providing fodder for livestock. This strategy has
therefore
been very important
for reducing the
effects of desertification by protecting the
environment,
but also in
supporting local
communities as well. This strategy is also very
sustainable.
Decide on the PE/PEE/PEEL paragraphs for a geography exam question discussing the effects of tectonic hazards in contrasting areas of wealth. Learn how to structure your answer, identify key words, and craft effective paragraphs to score well. Use examples like the Haiti earthquake to explain why impacts vary between Low Income Countries (LICs) and High Income Countries (HICs).
