Eric Cheung: An ancient aquatic system older than the pyramids has been revealed by the Australian bushfires
Extensive water
channels built by indigenous Australians thousands of years ago to trap and
harvest eels for food have been revealed after wildfires burned away thick
vegetation in the state of Victoria. The Budj Bim Cultural
Landscape, consisting of channels, weirs and dams built from volcanic rocks, is
one of the world's most extensive and oldest aquaculture systems, according
to UNESCO.
Constructed by the Gunditjmara people more than 6,600 years ago, it is older than Egypt's pyramids. While the aquatic
system was known to archaeologists - it was added to
UNESCO's World Heritage List last July -- additional
sections were revealed by the fires that have ripped through the state in
December. Gunditjmara representative
Denis Rose, project manager at non-profit group Gunditj Mirring Traditional
Owners Aboriginal Corporation, told CNN that the system was significantly
bigger than what was previously recorded.
"When we returned
to the area, we found a channel hidden in the grass and other vegetation. It
was about 25 meters (82 feet) in length, which was a fairly substantial
size," Rose said. He said other new
structures resembling channels and ponds were now visible in the burnt
landscape. "It was a surprise continually finding new ones that the fires
revealed," he added.
According to the
Aboriginal Corporation's website,
the aquaculture system -- which is part of the Budj Bim National Park -- it was
built by the indigenous population using the abundant volcanic rocks from a
now-dormant volcano in the area....
