An indigenous leader whose body was found deep in the Amazon rainforest in northern Brazil last month drowned, officials said Friday, after an autopsy found no signs of violence.

Tribal leaders had blamed Emyra Waiapi's death on "non-indigenous people" after finding his remains in a river on July 23 -- several days before heavily armed miners allegedly overran a village in the same remote area.

But an autopsy "found no traumatic injuries" that could have caused his death, according to preliminary results released by the attorney general's office in Amapa state.

It is likely that the man drowned accidentally sometime between July 21 and 23, said investigators, who are still waiting for toxicology results.

The tribal leader's death had caused international outcry, with the UN human rights chief linking the incident to President Jair Bolsonaro's pro-mining policies.

Rich in gold, manganese, iron and copper, the Waiapi's territory has faced growing pressure from miners, ranchers and loggers under Bolsonaro, who came to power in January promising to open up the Amazon to development.

The Waiapi's territory is one of hundreds Brazil's government has demarcated since the 1980s for the exclusive use of its 800,000 indigenous inhabitants. Access by outsiders is strictly regulated.

Deforestation in the Amazon has soared in recent months compared with a year earlier, according to official figures which Bolsonaro has dismissed as lies.

The rapid pace of clearing has strained relations between Brazil and Europe, which has been a strong critic of the forest destruction.

Norway on Thursday joined Germany in halting Amazon protection subsidies, accusing Brazil of turning its back on the fight against deforestation.

Bolsonaro retorted that Norway should send the money to German Chancellor Angela Merkel so "she can reforest Germany."

Trans-Brazil trail raises hopes for future of Atlantic Forest
Rio De Janeiro (AFP) Aug 16, 2019 - Luiz Pedreira walks with other hikers beneath the Atlantic Forest's thick canopy in Brazil, where an 8,000-kilometre (5,000-mile) trail stretching the full length of the country is being opened up.

He says he hopes that the creation of the trail, one of the world's longest, will raise awareness about the fragility of the forest -- long devastated by loggers and farmers, and now facing a renewed threat under President Jair Bolsonaro.

"If you don't know something, you don't value it," says Pedreira.

Inspired by long-distance tracks such as Canada's 24,000-kilometer Great Trail, the project will connect paths from the southern town of Chui on Brazil's border with Uruguay, to Oiapoque on its northern frontier with French Guiana.

The result will be a continuous coastal corridor for humans and animals.

Work is already under way on the trail, which has the backing of Brazil's environment and tourism ministries, but it could take years to complete.

"If you know something, if you are always in the forest, you will value it more," Pedreira tells AFP as he stands near a cliff offering 180-degree views of the heavily forested mountains and granite monoliths that divide Rio de Janeiro's neighborhoods.

"It allows people to connect to the forest."

- Tourist draw -

Ranked by WWF as the second most diverse ecosystem on the planet after the Amazon, the Atlantic Forest -- or Mata Atlantica in Portuguese -- is teeming with thousands of plant and animal species.

When the Portuguese first arrived in Brazil in the early 16th century, the forest covered more than 1.3 million square kilometers (500,000 square miles) -- an area roughly twice the size of France.

Since then, however, nearly 90 percent of it has disappeared -- destroyed over centuries to make way for coffee plantations, sugar cane fields, mining, cattle grazing or cities.

While the rate of deforestation has slowed in recent years, according to SOS Mata Atlantica Foundation, there are fears that Bolsonaro's anti-environment rhetoric will reverse that trend.

Deforestation in the Amazon -- a rainforest seen as crucial to keeping climate change in check -- soared 278 percent year-on-year in July, according to the National Institute for Space Research (INPE).

That follows a 90 percent increase in June compared to the year prior -- figures Bolsonaro has called "lies" and which prompted the recent sacking of INPE chief Ricardo Galvao.

"Unfortunately, this government isn't very good for the environment," French businessman and long-time Rio resident Yves Lahure told AFP after finishing a six-hour hike on a trail that will form part of the coastal track.

But history shows the forest can be revived.

Much of the Atlantic Forest that envelops Rio was felled for coffee plantations in the 19th century, says Horacio Ragucci, president of the Brazilian Excursionist Center, as he leads a group along a dirt path made by slaves.

A water crisis forced then Brazilian emperor Dom Pedro II to seize the land and reforest it, creating what is today Tijuca National Park.

Ragucci says the number of people visiting the forest has increased over the past 10 years, many motivated to find a scenic spot to snap a selfie.

"Today, groups meet on Facebook and gather 50 people to do a trail," Ragucci tells AFP.

Brazil's authorities hope the long-distance track will draw more foreign travellers to the country -- already a tourist hotspot -- to generate much-needed revenue and jobs.

"While the US receives 307 million visitors to its parks every year, earning $17 billion, Brazil receives just over 10 million visitors and makes two billion reais ($500 million)," former tourism minister Vinicius Lummertz has lamented.

"This data makes no sense -- we need to take action."

The trajectory of the trail is still being finalized, as authorities try to persuade private landholders in the forest to allow hikers, runners and mountain bikers to pass through their properties.

- 'Delight itself' -

"If I could do it every week, I would," says Andreza Albuquerque, as she and a group of hikers take a break during their walk, their sweaty backs to the trees as they gaze over the sprawling city and Atlantic Ocean below.

"When Monday comes around, you start work with a totally different energy."

Nearly 200 years ago, British naturalist Charles Darwin expressed similar sentiments after visiting the Atlantic Forest for the first time.

"Delight itself, however, is a weak term to express the feelings of a naturalist who, for the first time, has wandered by himself in a Brazilian forest," Darwin wrote in his diary in 1832.

Lahure says he supports the idea of a trans-Brazil trail, though he worries the forest could one day attract too many nature lovers.

"We have a city of six million people," Lahure says, referring to Rio.

"If everyone comes to Tijuca forest, it will be finished."

Mexican start-up fights air pollution with artificial trees
Puebla, Mexico (AFP) Aug 15, 2019
Trees are one of the best things we have to clean the Earth's air, but they have certain drawbacks: they need time and space to grow. Enter the BioUrban, an artificial tree that sucks up as much air pollution as 368 real trees. Designed by a Mexican start-up, the towering metal structure uses microalgae to clean carbon dioxide and other contaminants from the air, returning pure oxygen to the environment. Measuring 4.2 meters (nearly 14 feet) tall and nearly three meters wide, the device look ... read more
