Sudan

Sudan is in north eastern Africa and is suffering greatly from desertification. The land in Sudan lacks water and the forestation is diminishing. The lack of water is due to the climate and weather of this area and the deforestation is being caused in part by Darfur. The rainfall in Sudan is very low, some areas only get up to 24 millimeters of rain each year. The least rainfall is in the northern part of Sudan and this is where desertification is the biggest problem. In southern Sudan there is more rainfall so desertification is less of an issue, but the desert is encroaching on healthy land.
Darfur is causing camps to be created throughout Sudan, this is causing many people to be in one area all at one time. The grazing of livestock, farming, and collection of firewood in these areas contribute a considerable amount to the deforestation and loss of vegetation. Sudan is suffering from desertification, but the desertification in Sudan is stemming from another problem that they are faced with, Darfur. In order to prevent, and hopefully decrease desertification, political and social problems within Sudan must be addressed first.

TUNISIA DESERTIFICATION

Nick Brown

One major problem throughout Northern Africa is desertification, Tunisia having one of the worst overall soil conditions of all. Poor farming techniques such as overgrazing, deforestation, soil erosion, and a limited supply of natural sources of freshwater are all contributing to the problem of desertification. Agricultural land is growing extinct, not only because of desertification, but also because of increased salinity and siltation due to increased erosion of soil. Desertification and Tunisia’s failure to dispose of toxic and hazardous materials now endanger the health of its human population. Extinction is a common factor in the country of Tunisia not just in terms of plants and agricultural crop, but animals and humans. (see Threatened/Extinct species data tables) Living conditions are so bad currently, that animals don’t have a supporting environment and humans can barely get by. (soil erosion is leading to increased siltation and salinization of Tunisia's freshwater supply) Also, like many countries, Tunisia has fallen far short of the ideal global total of ten percent of its land under some sort of environmental protection, protecting less than half a percent of its land.
