Sahara is one of largest desert on the world and the largest in Africa. On the world map, Sahara extend over 3,500,000 square miles from the Red Sea side to the Africa’s Atlantic Ocean and cover parts of countries like Mauritania, Morocco, Niger, Algeria, Chad, Egypt, Libya, Mali, Western Sahara, Sudan and Tunisia. Sahara found along the Tropic of Cancer, between 15 and 30 degrees north of the Equator that reason created Sahara desert. Sahara is most severe climate on the world and features a hot desert climate on Koppen climate classification. Typically, the landscape experiences hot and extremely dry. The average temperature is over 30 degrees Celsius but during the summer, daytime temperature can soar over 50 degrees Celsius and the highest

The reason for desertification is an advanced stage of land degradation and “The diminution or destruction of the biological potential of the land, which can lead ultimately to desert-like conditions” (UN Secretariat 1977). It occurs when temperature hot and dry for long time in arid, semi-arid, ore dry sub-humid areas, which the land’s productivity becomes “dead” soil. Besides that, human activities and climatic variation are contributing to desertification. Many countries depend on agricultural activities that make soils become damaged when the farmer neglect or reduce fallow period. That reason, it makes soils to lose organic matter, less plant growth and decreasing vegetation cover as an effect. The climate is directly affected to desertification. The high and sustained temperatures for long time with infrequent and irregular rainfall. It leads to drought with the effect that vegetation has difficulty to live. Some researchers consider human to be the contributor to desertification processes, and climate factors playing a relative minor supporting role. According Le Houerou, “on its edges the Sahara is mainly made by man, climate being only a supporting factor" (quoted in Rapp, 1974,
