- The Sahara was a lush meadow dotted with Lakes 6 000-16 000 yearsago
- An archaeologist claims that human colonization caused the Saharadry up
- He said that the producers changed the flora of the desert and its exposed soil cultures
- The sunlight bouncing off the ground warmed up the atmosphere and dry the rain
But there are a few thousand years, it was grass and dotted with Lakes.
An archaeologist is now suggesting that humans triggered radical transformation of the desert, claiming that farmers set off a chain of events that pushed the region to the dry and arid State.
The Sahara desert is known today as a vast arid plain exposed to punish the temperatures and precipitation bit.
But there are a few thousand years, it was grass and dotted with Lakes.
An archaeologist is now suggesting that humans triggered radical transformation of the desert, claiming that farmers set off a chain of events that pushed the region to the dry and arid State.
The desert was green during the "African humid period", in which West Africa became much wetter than it is today through a series of monsoons.
Africa has gone through several of these periods of 'big wet' 9 million years.
African - about 16 000 to 6 000 years - wet period was the most recent of the continent.
Current theories suggest that an orbital axis 'wobble' in land 20,000 years the African humid period ended, but expert Dr. Wright is not convinced.
He thinks that the producers of human cultures has changed the landscape and this caused the desert to dry up.
Luscious green pastures of the Sahara began to dry up at the time that displaced people in the area 8,000 years ago, bringing with them agriculture.
In 1,000 years, it was transformed into the arid desert seen today.
Dr. David Wright of Seoul National University said that the producersof crops has caused this change.
His research shows that, as human communities spread throughout the region they veiled landscape to take account of crops and livestock.
Farmers have increased plant species that left the Saharan soil exposed.
They also brought animals who ate vegetation, discovering more ground.
As the light of the Sun reflected from the bare ground he heats the Saharan air.
In addition to farmers moving into the area, the ground was discovered, leading to additional warming of the air.
This reduced rainfall and created ideal weather conditions for the maquis vegetation.
Finally precipitation disappeared, killed a large part of the flora of the Sahara and leaving behind only a few hardy desert plants, says Dr. Wright.

A GREEN SAHARA?
The Sahara desert is showing signs of ancient rivers and traces of plants and animals deeply under its sands - the plain evidence more green past.The desert was green during the "African humid period", in which West Africa became much wetter than it is today through a series of monsoons.

The desert was green during the "African humid period", in which West Africa became much wetter than it is today through a series of monsoons.
Africa has gone through several of these periods of 'big wet' 9 million years.
The Sahara is the world's largest desert, stretching across 10 different African countries - an area over 3.5 million square miles (nine million square km)

He thinks that the producers of human cultures has changed the landscape and this caused the desert to dry up.
"In East Asia there are theories of Neolithic populations long-established how changed the landscape so profoundly the monsoon stopped penetrate to the Interior," he said.
Sahara is the biggest desert of the world, which extends over 10 African countries - an area of more than 3.5 million miles square (9 million km²).
The average rainfall varies with the largest part of the desert see less 0.79 inches (20mm) annually.
In the United Kingdom, the average annual rainfall is more than 44 times that 33.7 inches (85cm), with U.S. average annual rainfall up to 30 inches (76 cm).
But there are a few thousands of years weather of the desert have been very different.

"It was 10 times as wet as it is today," said Dr. Jessica Tierney of the University of Arizona, a paleoclimatologist and a Sahara expert not involved in the research of Dr. Wright.
But human colonization of space time-luscious finally forced the man to leave.
"It seems that this 1000 years dry period caused people to leave," said Dr. Tierney.
"What's interesting is people who came after the drought period were different - most were the cattle."
"This dry period between two different cultures.
"There is a context of climate for this change of occupation and lifestyle in Western Sahara".
Dr. Wright now plans to gather evidence in support of his theory.
"There are Lakes everywhere in the Sahara at this time, and they will have the records of the changing vegetation," said.
"We must dig in these ancient lake beds to get the records of vegetation, look at archaeology and see what people were doing there."
