A team of archaeologists in Bolivia said they have discovered tombs containing over a hundred bundles of artifacts and human remains dating more than 500 years old that belonged to an indigenous civilization that once inhabited the region.
Bolivia’s Ministry of Cultures and Tourism authorized the dig more than three months ago after a mining project discovered archaeological remains in the area.
Archaeologists found the tombs, which they say may have belonged to the Pacajes people, in an underground burial chamber located some 30 kilometers (18.6 miles) southwest of Bolivia’s capital La Paz.
“Inside the cemetery we found two special tombs, one of which had about 108 individuals inside. They were badly deteriorated, but we were able to recover objects the individuals were buried with,” said archaeologist Wanderson Esquerdo.
While two of the tombs had been ransacked, the others remained intact, he said.
To reach the tombs, scientists had to lower themselves through a circular chimney just 70 cm (27.5 inches) in diameter and 3 meters (9 feet) deep.
In addition to human remains, the largest tomb contained metal objects as well as ceramic and wooden dishes.
“There are objects that are clearly attributed to the Inca culture, and others that are not Inca, but rather Aymara,” Esquerdo said.
The indigenous Aymara kingdom of Pacajes flourished in the Bolivian highlands until it was conquered by the Incan empire in the mid-15th century, according to archaeologists, who believe the Pacajes people may have not been wiped out by the Incan conquest, but could have fallen victim to some type of epidemic.
The discovery is “unique and unprecedented,” said Wilma Alanoca, Bolivia’s Minister of Culture and Tourism.
After the archaeological dig began last June, archaeologists said microorganisms wreaked havoc on the bodies’ soft tissue, quickly decomposing the remains. Excessive humidity and high salinity inside the chamber also deteriorated many of the buried objects, according to the dig team. (VOA)
High up in the Bolivian cloud forest, a woman tends to her bees, smoker in hand, working from hive to hive under a canopy of leaves to delicately gather panels of honeycomb. It’s a bucolic scene that experts say won’t last, for the bees are dying.
The culprit — as in so many other cases across the world — is pesticide. The difference in Bolivia is that pesticide use, along with the coca plantations it is being used to protect, is on the rise.
Environmentalists and beekeepers like Rene Villca say the bee population is being decimated by massive and intensive use of chemical pesticides to protect the region’s biggest cash crop.
Here in the idyllic Nor Yungas region north of the cloud-high capital La Paz, the pesticides are taking a toll on Villca’s hives.
“Of the 20 hives I have, 10 are producing normally and 10 are not.”
On another part of the mountain where Nancy Carlo Estrada tends to her bees, a canopy of protective netting around her head, Exalto Mamami wades through a waist-high coca plantation, pumping out liquid pesticide from a canister on his back, face covered with a long cloth against harmful blowback from the spray.
He is all too aware of the pesticide’s toxicity, but has other priorities.
“We use pesticides because the pests eat through the coca leaves and this affects our income. The plants can dry out and that way we as coca farmers lose out economically,” said Mamani.
The sale of coca leaves — the base component of cocaine — is legal in this part of Bolivia. They are sold openly for traditional use in the local towns. It is chewed, used for making teas, and in religious and cultural ceremonies.
According to the latest survey by the U.N. Office on Drugs and Crime, Bolivia has 24,500 hectares under coca cultivation, an increase of 7.0 percent in a year. The government is collaborating with the UNODC in alternate development programs but despite this, between 35 and 48 percent is destined for cocaine production.
Coca cultivation expanding
On the steep slopes of the region’s valleys, the lush forest is pockmarked with small plots of coca arranged in terraces.
“The area of coca cultivation has expanded and the native forest has been reduced to alarming levels,” said Miguel Limachi, an entomologist at La Paz’s San Andres University.
Limachi says the expansion of coca cultivation has helped to destroy other plants that provide a natural defense against the coca-leaf pests, particularly the Tussock Moth.
In other parts of the Andes, the pale moth has been used as a biological weapon against coca cultivation.
“A monoculture is more at risk from pests or fungi because there is no longer native vegetation — there are no natural controllers,” Limachi explained. “And then more pesticides are used in higher concentrations.”
Harmful organophosphates in the pesticides mean the bees — “a social insect and extremely organized,” according to Limachi — become disorganized, and less able to feed and care for larvae.
In recent years across the globe, bees have been mysteriously dying off from “colony collapse disorder” blamed party on pesticides, but also on mites, viruses and fungi.
The danger of increased pesticide use in the Bolivian highlands is that they “remain in the soil, on the surface of the plants and obviously contaminate all the organisms present — both the growers themselves, their children and their families, and the wildlife,” Limachi told AFP.
Pesticides are also used to protect other crops in the country such as coffee plantations and some tropical fruits.
‘Growers have no choice’
For Exalto Mamani, there is no other option but to use pesticides.
“Many of the coca growers are aware that we are affecting the environment with these chemicals, but we have no other alternative because the coca supports us and gives us the economy to support our family,” he said.
He says climate change has meant coca leaf pests are on the increase.
Limachi agrees that climate change has played a role in reducing bee populations.
“Very dry years and other years that have too much rain change the availability of flowers from which the bees use to feed the hives,” he said.
“Electromagnetic pollution, the emission of cellular waves, microwaves, radios, television…all that can affect their communication and the operation of the hive because they interrupt processes such as food collection, care of the larvae or cleanliness of the colony,” said Limachi.
On the lush steep slopes around Coroico, beekeeper Villca has no doubt about the immediate threat to his bees.
“We hope that the coca producers realize the value of this golden insect,” he said. (VOA)
