The Saharan Desert

  1. 1. Anosh Ali &Rodrigo Mojarro
  2. 2.  The Sahara desert is the second biggest desert after Antarctica. It is 9400000 square kilometers long covering most of North Africa. It stretches from the Red Sea including parts of the Mediterranean coast to the even the Atlantic Ocean.
  3. 3.  Historically, thousands of years ago people lived on the edge of the desert. The Sahara was much wetter than it is now.• Over 30000 petrogphys of river animals like crocodiles have been found. Also have found many fossils of dinosaurs.
  4. 4.  Modern day the Sahara is not full of vegetation like it once Due to a climate change the savannah changed into the sandy desert we now see. • Some Mediterranean plants grow here such as the olive tree.• The region has been this way for about 4200 years.
  5. 5.  Not much of the desert has been changed besides small cities and settlements usually by oasis. However, the local pressure on natural resources can be intense. The remaining populations of large mammals have been greatly reduced by hunting for food and recreation
  6. 6. • There are many big animals that are edible such as camels ostrich antelope and dorcas gazelle.• Some of these animals can live without drinking water for over a year. • Lack of illness, crime, pollution, predators • Beautiful • Solar energy
  7. 7. • The prospects for the Sahara arenot to bad, however.• With continued hunting in regionsof the Sahara, the populations ofcertain animals that inhabit it maydecrease in the future.• The Sahara will have less trees dueto increased deforestation andvegetation will also decrease due topastoralism.• However in the next centuries dueto climate change the Sahara willwarm up to about 5-6 degrees.• Evaporation in the ocean will causethe Sahara to become a savanna andwith more rainfall in the future itwill become greener and have morevegetation.
  8. 8.  The Sahara overall is not heavily protected because many people do not live within its range and the people who do inhabit it are nomadic. The Banc d’ Arguin National Park and Reserve Integrale de Cap Blanc of the Atlantic Coastal desert in Mauritania are protected areas. Both of these protected areas are degraded due to drought, overgrazing, and hunting. The Ahaggar National Park and Parc National de Tassili N’ajjer are also protected areas from the Montane Xeric woodlands. These areas have minor woodcutting and poaching problems. These areas however are strongly protected due to tourism.
  9. 9.  What can be done to maintain balance between the Saharan desert and humans is a strict law that would reduce the hunting of animals. There should also be a restriction that would limit the amount of trees being cut as deforestation is increasing in the area.
