Its environment is hot, dry, dusty harmattan winds occur in the north, drought and desertification affecting much of the south, and subject to plagues of locusts.

"Erased/deleted old title which did not make sense within body of essay" The Middle East is a region in Southwest Asia that includes the countries of Saudi Arabia, Yemen, Oman, U.A.E., Kuwait, Iraq, Jordan, Israel, Lebanon, Syria, Cyprus, Turkey, Iran, and Afghanistan. The aspects that make up all that is geography in the Middle East include physical geography, economic geography, religion, and human history. The Middle East is known for its physical geography, being the largest area of dry climate in the world. Southwest Asia is mostly desert and steppe climate because of subtropical high pressure over the area which keeps the region dry and the air warm. Some places around the Mediterranean Sea have a Mediterranean climate.
These two deserts are a natural detriment to the African continent because they make it difficult to reach the inland where most of the people live. Although Africa is relatively close to Europe, travel by land over the Sahara desert is very prohibitive. Another topographical feature that also isolates the central region of Africa is the coastline. Africa has a regular coastline characterized by few indentations. Because of the smooth coastline, natural harbors were non-existent.
The Negev desert is characterized by its lengthy, waterless summer with rain events occurring during the colder months of the year. Hendrik Bruins adds in his article, “Ancient Desert Agriculture in the Negev and Climate-Zone Boundary Changes During Average, Wet and Drought Years”, that: The amount of average annual rainfall ranges from 300 mm in the northern Negev to only 25 mm in the southern Negev…Cereal food crops like wheat and barley require at least 250-300 mm to obtain a reasonable yield. Fruit trees, including grape vines, olives and pomegranates need more than 400 mm of precipitation. Therefore, most of the Negev is too dry for agriculture based only on rainfall. In short, agriculture reliant purely on levels of sufficient rainfall was destined for failure in the Negev desert region, which is characterized by its low precipitation and high evaporation.
