Desertification has become a major issue in Africa,
specifically in sub-Saharan Africa. The area most at risk is the Sahel, the area that borders the
southern edge of the Sahara. This region serves as a “transition” between the
desert and savanna the
grasslands that dominate much of sub-Saharan Africa. The centrally-located tropical rainforest region is
not immediately affected by the threat of desertification.
The term
“desertification” refers to the growing size of deserts, but in this case the Sahara. There are many causes of
desertification: some are naturally occurring while others are caused by
humans. The most common natural cause is drought,
which is something you might associate with the desert itself. However, this
situation can cause great harm to soil, making it unusable and causing<span> erosion</span> by wind or human
activity.
As far as human activity goes, there are number of them that cause
desertification. Cattle ranching- a common occupation in much of rural Africa-
can cause overgrazing.
Additionally, the need for more and more food to feed people in and outside of
Africa results in over-farming.
In both cases, these practices cause soil to become more exposed to the sun and the increasingly dry weather. As the
soil loses nutrients and is loosened by other forces, it ceases to be able to
grow any plant life, creating a situation in which the desert may slowly begin
to creep into an area.
The effects of desertification can be catastrophic. Starvation is the most common
effect, and one that is not quickly or easily solved. Soil that is unusable can
take many generations to replenish.
Similarly, ending or slowing down desertification is cannot be done with a
single effort. Military
campaigns are being undertaken in Africa, encouraging the use of beneficial
practices such as crop rotation
and smarter ranching
practices in order to prevent further soil depletion.
A <u>seasonal</u> worker is someone who travels from one area to another picking crops that are in season and that location
<u>Explanation</u>:
A person is said to be a worker if he/she does specific work in a specified way. A seasonal worker is a person who is hired for working in the particular season. This seasonal worker does not work for the whole year. Farming workers are hired as the seasonal workers during farming or planting or picking crops.
The seasonal workers generally travel from one place to another to pick crops that are in the season. They are particular about the location too. There are some species that are famous in specific location.
When connecting past and present issues, it is best to follow a series of steps seen as
1. Identify common issues in the past and the present.
2. Research supporting evidence.
3. Validate the outcomes of the two events. Option C
4. Make connections.
5. Draw conclusions.
<h3>What an
event?</h3>
Generally, something that takes place or occurs, especially anything significant; an occurrence; an incidence
The "event" that was recorded in history was the result of a process that had more or less arbitrary limitations placed on its scope and its subject matter. There is a beginning, a middle, and an end to every occurrence.
