Human interaction in the sahara desert

By Brooks Hays 0 The Sahara was once green, and new research suggests human activities may have delayed its transition to desert by years. The influence of hunter-gatherers and pastoralists may explain the delay in desertification.

Now, in vast portions of the Sahara, merely rock, sand and sparse vegetation are found. The remnant large mammal fauna is highly threatened by ongoing over-hunting. There is also an intense pressure on any remaining populations of large mammals adapted to desert conditions.

The populations of all such species have been greatly reduced by hunting for food, and also through hunting for sport and recreation. The addax Addax nsaomaculatus is now critically threatened with extinction, mainly due to intense over-hunting, and most of the other desert-adapted antelopes that may still occur in the ecoregion are endangered.

People use the Sahara to build homes, out of the sand, and to create communities within the Sahara. The Sahara is a vast area of largely undisturbed habitat, principally sand and rock, but with small areas of permanent vegetation. The most degradation is found where water oases, etc is present.

Here, habitats may be heavily altered by human activities. Previously existing tree cover has often been removed for fuel and fodder by nomadic pastoralists and traders.

From a conservation perspective, the Sahara Desert is not well protected. Yet, this may be due to the low population and impracticality of defining borders over this vast area. Fewer than two million inhabitants reside throughout the entire Sahara Desert.

The majority are nomads, predominantly the Tuareg, Tibbu, and Moors. They survive by nomadic pastoralism, hunting, and trading. Most of these people are found in the desert margins and they do not often spend much time in the central hyper-arid portion.

The ephemeral habitats of the Sahara, which only develop following rainfall, are not highly threatened by human activities. The more persistent pressures are found in ar eas of permanent water oasesor in areas where water comes close to the surface. Here, the local pressure on natural resources can be intense.

In recent years development projects have started in the deserts of Algeria and Tunisia using irrigated water pumped from underground aquifers. These schemes often lead to soil degradation and salinization because of "drainage" problems.

Zellaf Nature Reserve in Libya!!!Thats what I would call human environmental interactions in the Sahara Desert . How do you get out of the Sahara Desert? Ha-ha, not easy, but if you knew where your relative position was the best thing would probably to head towards the coast (which ever was the closest).

Human and Environment Interaction Adapted - Egyptians wore thick, loose clothes which would keep them cool in the Sahara's scorching heat. They also rode camels so that they could survive trips which would have them cross the entire desert.

It is desert due to lack of water, lack of farmable land, the type of flora and fauna that live there, climate, and vast amounts of sand. It gets very hot in the day and cold at night. It .

Desertification of the Sahel

Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities.

Desertification is a significant global ecological and environmental problem. resulting from human interaction either by deforestation or by the over grazing of farm animals.

Case study: Las Vegas and the Mojave Desert

As the plant life is destroyed, winds blow the fertile soil away, thus spreading the desert. The Sahara Desert in Africa is spreading about 50 miles a year due to this process.

In North Africa. Ouarzazateis a desert town in Southern Morocco that is known for having dry, clean air because of its mountain ranges and proximity to the Sahara desert. For this reason, as recent news suggests, Morocco’s King Mohammed VI has decided to build a desert palace here.
