Africa > Landscape and climate
Landscape and climate
Climate:
Africa has several different climates. You mostly can recognize a
climate on the landscape. In the middle of Africa it is very humid and
hot. In the north it is very dry and hot. In fact, there are many
differences.
The savannahs are sometimes hot and dry,
sometimes very humid. A farmer goes to places where
the temperature, the soil and the landscape is good enough for grocery.
Some areas, like deserts or steppes are not good enough for agriculture. At
the left you see a map of Africa. The dark green parts are the
areas where you can find rain forests. The light green areas are
savannahs.
North and South of the savannahs are the steppes (purple) and the yellow
parts are desert areas. Finally, the blue areas are areas where you can
find a mixture of some climates (mostly caused by the present of the
oceans) Rain
forest:
Tropical rainforests are mostly densely overgrown with all kinds of
trees. We read that there are more than 100 different kind of trees!
Some of the trees grow higher than 40 meters.
There is rainfall each day and the temperature is mostly very high.
To cultivate the soil is difficult. Not all areas are useful for
agriculture. If a farmer cannot use his ground anymore, then he moves on
to another place in the forest, put it on fire to create open fields and
then they will use it for agriculture for a couple of years. The ashes
of the burned trees are a kind of muck, but after some years, the fields
are useless. Which means that the farmer has to move on again.
This is not good for the rain forest; the rain forest in increasing
dramatically... it will have much consequences for human being, since
the tropical forests are the lungs of planet Earth!
Savannah:
The steppe and the savannah look alike. In fact, the only big difference
between them is that savannahs have grasslands with here and there
trees, and steppes are dry areas with here and there some grass.
Sometimes it is hard to say if the area is a steppe or already a desert.
Savannah areas mostly have two rain seasons: the long rains and the
short rains. During the months between the rain seasons it can become
very hot and dry. Farmers in these areas mostly use all the things they
have on their fields for themselves. If they are lucky, they have enough
to sell on the markets. Comparing to other areas, the savannahs are the
best places to have agriculture.
Steppe and desert:
Steppes can be found around deserts. The two well known deserts in
Africa are Kalahari desert and the Sahara. The steppe grass can survive
dry seasons for a long time. You will not find much trees on steppe
areas. The wet season is only a short season. So, even the fact that the
soil is suitable for agriculture, it is hard to survive in this area
because of the lack of enough water.
Cattle holders mostly go from one place to another, trying to find
enough grass and water for the animals.
Deserts are bad places to live, since there are no trees, no grass,
almost no water. Animals are good to have in the
steppe and savannah, since you can use them for working on the fields.
Most work on the fields is done by animals. The farmers mostly use a
simple plough. To conclude: it is not easy to
be a farmer in Africa: soil is not good enough in many places, problems
with enough water, not enough food for animals.
