Awa men are skilled hunters who hand-make their own bows and arrows. Awa tribespeople depend on the forest for their hunter-gatherer lifestyle.

A new international campaign hopes to save a group of people who have been dubbed "the most threatened tribe in the world" — the Awa tribe of Brazil — from encroaching outsiders who are gobbling up their land.

The Awa live in the Brazilian state of Maranhao on lands set aside for their hunter-gatherer lifestyle. But according to the tribal advocacy group Survival International, which is leading the new campaign, the tribe is increasingly under threat by illegal settlement and logging on their lands. One reserve set aside for the tribe, the Awa Territory, is one-third deforested, its trees stripped by illegal logging operations, some with sawmills operating only miles from Awa land.

"When the forest is destroyed, they either flee or they simply die," said Survival's field director Fiona Watson, who has worked with and interviewed many of the 360 surviving Awa who are in contact with society. On her last visit, she told LiveScience, "They were saying to me, 'We're suffering from hunger now.'" [ Photos: One-of-a-Kind Places on Earth ]

Tribal life under threat
The issue of indigenous people's land rights is an international one. Survival International estimates more than 150 million tribal people currently live in 60 countries worldwide. The most voiceless of these are uncontacted tribes, people who live without interaction with the outside world.

Uncontacted tribespeople are often romanticized as "primitive" people who aren't aware of the outside world, which is a myth, according to Survival. In fact, many are purposefully avoiding society after deadly run-ins with civilization in the past. Not only do clashes between native peoples and settlers sometimes result in violence, uncontacted people lack immunity to common diseases and can be felled by a simple flu virus.

Survival estimates that there are about 100 uncontacted Awa in addition to the 360 or so who have semi-settled in villages on their legally protected land. After first contact with the Awa in 1973, the Brazilian government has opened up the region where the tribe has long roamed. After iron ore was discovered in the area, the European Community and the World Bank even helped fund a railway and other developments in the region.

"This acts like a magnet for settlers to pour in, and ranchers, so Awa land started to be invaded," Watson said.

Land rights battle
The Awa's right to their land was formally recognized in 2005, making mining and other activities by outsiders illegal; but satellite photos of the forest reveal that these rights are not being honored. Illegal logging has left the scar of deforestation on the land. This is especially devastating to the Awa, who depend on the forest for their survival, Watson said.

"When you talk to the Awa, it's just so clear how much the forest means to them," she said. "They just get everything from it."

That includes food — babacu nuts and acai berries as well as fresh meat — and medicines and supplies, such as the resin of the macaranduba tree, which is used to make torches. [ See Video of Awa Life ]

As the forest vanishes, the Awa are trapped in a legal battle to save it. In 2009, a federal judge ruled that illegal settlers had to leave the Awa territories within 180 days. A legal appeal by one of the largest cattle ranchers in the region delayed the ruling. In December 2011, a second federal judge ruled that colonists and ranchers had to leave the land by December 2012. Survival fears that continued legal wrangling will delay these departures, too. If the case continues in the legal system, it could take 20 or 30 years for the Brazilian Supreme Court to decide it. By that time, it will be too late for the Awa.

"Time is not on their side," Watson said.

Violence and protection
In addition, reports from Awa tribe members and from the Brazilian Indian affairs office FUNAI suggest that this land controversy can all too easily turn deadly. In 1988, for example, townspeople in west Bahia, Brazil, met a lone native man who turned out to be of the Awa tribe. The man, Karapiru, had been living alone in the forest since 1975, when ranchers killed his daughter and wounded him and his son. The ranchers had taken his son, leaving Karapiru to believe him dead.

"It's a violent part of the Amazon," Watson said. "You have bows and arrows against guns."

Other tribes have also been haunted by violent clashes. In August 2011, FUNAI officials were alarmed to find evidence of a fight between drug traffickers and uncontacted native people, who went missing after the violence. 

Watson and her colleagues are hoping that their new campaign will put pressure on Brazil to honor the Awa's legal right to their land and provide the funding needed to enforce the protected areas' borders.

"It's a very simple, direct message to the Minister of Justice," Watson said. "The land belongs to the Awa."

Explainer: Tales of seven cities, lost and found

  • Science / AAAS

    The Lost City of Z, a fabled metropolis of unimagined riches deep in the Amazon rain forest, has eluded explorers for centuries. But recently documented traces of a well-planned constellation of walled settlements arranged around central plazas and linked together with arrow-straight roads in the Upper Xingu region of the Brazilian Amazon may be the civilization that gave birth to the legend, scientists say. This image shows the charred remains of a house in the region that was uncovered as part of an archaeological project led by the University of Florida's Michael Heckenberger.

  • Atlantis legend inspires hotel chain

    Joel Ryan  /  AP

    According to the Greek philosopher Plato, Atlantis was a powerful society that disappeared under the sea in a torrent of earthquakes after it failed to take the city of Athens. Some scholars consider Plato's account as purely fictional; others have scoured the world for evidence of its existence. One disputed theory holds that Atlantis was on a portion of the Mediterranean island Cyprus that was submerged during an earthquake thousands of years ago. The mythical allure of the lost city has spawned a luxury hotel chain. In this image, fireworks explode over the opening of the Atlantis resort in Dubai.

  • What happened to the lost colony of the Americas?

    Gerry Broome  /  AP

    Sometime in the late 1580s, 117 English colonists disappeared while attempting to become the first to settle the New World. Their settlement on what would become Roanoke Island, N.C., was found abandoned in 1590. To this day, scientists, scholars and the plain curious can't agree on what happened. Some people believe the colonists assimilated with neighboring Native Americans; others think they were either killed by their neighbors or sunk at sea while trying to flee. In the image shown here, Frank Ray, a member of the Lost Colony Center for Science and Research looks for clues that could help solve the mystery.

  • Lost city of Ubar found


    From about 2,800 BC to AD 300, the city of Ubar in the Arabian Desert served as an outpost for the lucrative trade in frankincense, a sweet-smelling gum resin. Then, according to myth, the city sank in the sand, lost forever. And so it was until archaeologists armed with everything from ancient texts to remote-sensing technology on the space shuttle went looking for the lost city. The diffuse reddish streaks in this radar image from the space shuttle show ancient paths leading to and around the ancient site, which had literally sunk into an underground water hole. Ubar's discovery is an example of scientific sleuthing verifying ancient lore.

  • Lost city of the Incas remains a mystery

    Giulio Magli

    In 1911, U.S. explorer Hiram Bingham scrambled up a steep mountain side in southern Peru and encountered an ancient city of sorts beneath the undergrowth. The site, Machu Picchu, is popularly known as the Lost City of the Incas. What exactly the city was, however, remains a mystery. Scholars have variously theorized it was the birthplace of the Incas, a private estate, and a spiritual destination. Prior to Bingham's encounter, the city was lost to the jungle for about 500 years.

  • Itil, lost capital of Khazars, found?

    The excavated buildings shown here south of Moscow, Russia, may be remains of Itil, the capital city of the Khazars, a Russian scientist has reported. The Khazars ruled the steppes from Northern China to the Black Sea between the seventh and 10th centuries. Once conquered by the Russians, Itil disappeared without a trace. Some scholars believe it was swamped by the nearby rising Caspian Sea in the 14th century. Scientist Dmitry Vasiley at Astrakhan State University believes these flamed brick buildings are part of what was once Itil.

  • Layers of Troy found in Turkey

    Homer's epic poem the "Illiad" famously describes a war in the city of Troy, replete with tales about the heroic Greek warrior Achilles and a wooden horse. Questions about whether the city really existed appeared resolved in the 1800s when journalists, archaeologists and others zeroed in on a site and excavated the ancient city. The so-called archaeological Troy consists of nine cities built on top of one another and denoted with Roman numerals. Scholars believe Troy VI and Troy VII correspond with the city described in the Iliad. This image from the movie "Troy," which was based on the Iliad, shows the famous Trojan horse.
