6a)Soil can be defined as the organic
and inorganic materials on the surface
of the earth that provide the medium
for plant growth.
6bii Clay soils with 25-40% clay
These soils have a good ability to
transport water by
capillary action from deep layers but
the rate is slow, so plant water
requirements are not met through
capillary water.
2 These soils are darker in colour and
soil aggregation is more distinct.
a) *Causes of Desert Encroachment*
1. Human activities: such activities
such as over-grazing, over-cultivation,
bush burning, and excessive cutting of
firewood greatly reduce the vegetative
cover and expose the land to drought
and desertification. Examples of areas
with desert encroachment are the
Sahelian zones of Nest Africa,
Ethiopia, Somalia and Sudan.
2. Change in Weather: The frequent
and prolonged dry weather increases
the aridity of affected areas.
3. The southward movement of the dry
sub-tropical high pressure belt results
in severe drought in semi-arid regions.
b) *Effects of Desert Encroachment*
1. Large scale disruption of socio-
economic life arising from crop failure
and shortage of water and pasture for
2. Widespread malnutrition and
diseases such as kwashiokor and
3. Migration of people from drought
areas to more humid areas.
4. Large refugee population, that are
made up of victims of drought and
social insecurity in the semi-arid
5. Disruption of ecological balance and
loss of vegetation, soil and water
c) *Preventive Measures of Desert
1. Conservation of existing vegetation
through legislation against
indiscriminate exploitation and felling
of forests and trees.
2. Legislation and strong control
against bush burning.
3. Improved grazing practices.
4. Establishment of shelter belts to
protect the soil and arrest the effect of
5. Afforestation programs.
6. Integrated rural development.
Factors that affect Mass Movement
It is very clear, that mass movement
or mass wasting is movement of
weathered material with the aid of
gravity, there are many factors that
affect this movement. I shall tell you
about 6 main factors as follows:
1. Where permeable rocks alternate
with impermeable rocks, the
permeable rocks are more more prone
to mass wasting than the impermeable
2. Mass movement is pronounced in
areas with steep slopes where the
weathered layer is deep and the
weathered materials are loose.
Naturally, the rate of movement of
weathered materials is faster on steep
slopes than on gentle slopes.
3. Mass movement is encouraged if
there are earthquakes and volcanic
4. Areas with a high annual range of
temperature and a high frequency of
freezing and thawing will encourage
soil creep while areas with a high
temperature and occasional torrential
rainfall encourage mudflow.
5. Mass movement is also encouraged
if there is no vegetation.
6. The activities of man like mining
and herding of animals encourage the
production of mass movement or mass
wasting. This are the factors that
affect Mass movement or wasting.
