Overall Human Influence

• Many types of human activities affect Desert biome

If you run vehicles over desert you can scar soil and it can be scared for many years

Car tracks can kill vegetationAnimals that rely on desert can be harmed

Atacama Desert

• Location: Northwest Chile • Landscape: Dry, Mountains, sandy, rocky,

some valleys • Human impact: This desert has a hand

sculpture (finished in 1992) which COULD lead to destrohind ecosystems

Patagoian Desert

• Location: Argentina and a little in Chile• Landscape: 7months winter 5months summer,

rocky, valleys, cliffs, streams, sandy• Human Influence: Some humans have lived

here mostly to herd goats and sheep. Also for oil, gas, and coal. About 5% of Argentina's population takes over 28% of the territory of the desert.

Kalahari Desert

• Location: Southern Africa • Landscapes: Sandy, rains ( frequently in winter

and little in summer ) Total= 100-200 mm. per year

• Human Influence: Tourism can often get in the way of daily routines and animal ecosystems. In the end it only has minimal impact.

Aribian Desert

• Location: Egypt and Iraq• Landscapes: sand dunes, some cliffs• Human Impact: Humans haven't really

affected this desert. Although the demand for more shopping malls around it could end up affecting the desert.

Taklamakan- Gobi Desert

• Location: Middle of Russia • Landscapes: high mountain ranges, sandy

( partly ), mostly lowlands ( besides the mountains )

some parts have bunches of plants • Human Influence: Humans have not really

affected this desert in any way.

Chihuahuan Desert

some hills, flat other than the few hills, very little rain fall

• Human Influence: Jas many human activities, tjis could potentially affect the ecosystems in the desert.

Sonoran Desert

• Landscapes: very full of plants, hills, boulders, and sand/rock mixed ground.

• Human Influence: There were native tribes in the pre-colonial times who lived in and around this desert. It has destroyed the desert with over harvested plants

Tanami Desert

• Location: Northern Australia • Landscapes: very little plant life, sandy, muddy

( in some areas ), hilly ( UP AND DOWN)• Human Influences: It ahs been unfavorable to

humans living in these areas. But the human activities can still bring harm to the ecosystem's.

Sahara Desert

• Location: Sudan and Libya • Landscapes: somewhat flat, has some dents in

the ground, rivers, some plant life• Human Impact: humans have been living in
