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 vegetation
Animals 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 )

farmland. It is still affected from the Asian
monsoon.
Thar Desert

• Landscapes: grass spots, few trees, sandy,
hilly, some parts have bunches of plants

affected this desert in any way.
Chihuahuan Desert

• Landscapes: some plants, rugged ground,
some hills, flat other than the few hills, very
little rain fall

tjis could potentially affect the ecosystems in
the desert.
Sonoran Desert
• Location: Northwest Mexico and southwest
U.S
• 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
