Marina Silva Wants to Be Brazil's Greenest President

On Sunday, nearly 136 million Brazilians will be heading to the polls to elect a new president, and for a country on the rise with such a wealth of natural beauty, there may be more at stake than just politics. Among the leading candidates, one has put sustainable development at the top of her agenda. Meet Marina Silva -- she wants to be Brazil's Green new president.

It's no surprise that environmental issues are at the heart of Silva's campaign; Born in 1958, she grew up alongside rubber tappers in the Amazon rainforest as one of eleven children. It wasn't until she was orphaned at the age of sixteen that she learned to read and write, getting a job as a housemaid. Eventually she would enroll in university where she developed an interest in politics. In her speeches on the campaign trail, she would refer to education as the "miracle" which helped carry her from poverty.

She got her start in politics in the mid-90s, becoming the first rubber tapper to be elected to the Brazilian senate. Silva, as senator, was a leading proponent for stronger protections of the Amazon rainforest and economic support for the people who live in it, placing special emphasis on sustainable development in the region.

Many of her political stances were shaped by her early mentor, environmental activist Chico Mendes. A rubber tapper by trade, Mendes fought to preserve the rainforest which sustained the profession, opposing development and deforestation from cattle farmers and loggers. In 1988, he was assassinated by a group of ranchers.

When fellow Worker's Party member Lula was elected president in 2003, he appointed Silva as his Environmental Minister, a position she held until 2008. During her tenure as minister, she was no stranger to criticism. Her commitment to the environmental cause frequently stirred ire from members of her own administration, particularly when economic interests threatened the preservation of the Amazon.

Despite the friction she caused in the Lula's cabinet, she became known internationally for her support of the environment. She was named a Champion of the Earth by the United Nations Environment Program in 2007, and has since garnered numerous other awards.

She opposed many projects which would have had detrimental impacts on the environment, like the creation of highways and dams. After a series of disputes with government officials and business leaders, who saw her as an impediment to development in the Amazon, Silva submitted her resignation from the position of Environmental Minister in 2008. To many environmentalists, this weakened the prospect that Brazil would continue to advocate sustainable development over opposing economic interests. "I'd lost the strength to carry on," she would later recall.

"There is no longer a way of thinking about growth for growth's sake," says Silva. "Growth is important, but it needs to be growth with development and sustainability, in all of its senses: social, environmental, economic, cultural."

A year later, Silva left the Worker's Party, citing the party's "conception of development focused on material growth at any cost" as the reason why. In May of 2010, she announced her candidacy for the Presidency as a member of the Green Part, hoping to ride the wave of international popularity she had enjoyed throughout her political career.

During the months preceding election day, Silva has put the concept of sustainable development at the center of her campaign -- though the issue has been largely drowned out by the two leading candidates, Dilma Rousseff and José Serra.

Dilma, as she's commonly referred, served alongside Silva as Lula's Energy Minister. The two were prone to disagree, as Dilma's interests favored exploring energy and water resources despite the impact to the environment. She was later promoted to Chief of Staff where she was a vocal proponent of industrialization, supporting investment in nuclear and hydroelectric power plants which have been contentious issues among environmentalists.

José Serra, a right-leaning centrist and former mayor of São Paulo, shares many of the same "developmentalist" ideals as Dilma. "Rousseff and Serra were molded by the ideas of developmentalism and industrialization, that's why environmental issues do not figure prominently in their campaigns," political scientist Claudio Roberto told IPS.

Since the two leading candidates for president have largely defined the political discourse this election cycle, Silva's environmental agenda has struggled to sway the dialouge. Those watching her campaign have described it as "undefined," though Silva herself has taken aim at the press for not making the environment a bigger issue during debates and interviews with the candidates.

Despite her history of disagreements with Lula's hugely popular administration, Silva has gathered more support than most analysts were anticipating, with 13 percent support -- compared with Dilma's 50% and Serra's 27%. In Brazil, the winning candidate must receive 50 percent or more of the votes to be elected; if no one does, a run-off election is held between the two leaders. If she can overtake Serra at the polls and shave off support from Dilma, it would force a face-off vote.

While it may an uphill battle for Silva to arrive at the Presidential Palace, the candidate is hopeful that, come election day, there will be a "green wave," insisting that her supporters are more numerous than the polls reflect.

"Mobilizing society, constantly struggling for what is best for Brazil in education, health, public safety, economic and social development . This is how the Green Wave just keeps growing , and I will remain in a state of permanent campaign until the final moment," Silva promised.

Air archaeologists isolate 'pure' aerosol particles

EU-funded environmental engineers have isolated aerosol particles in near pristine pre-industrial conditions in the remote Amazonian Basin in Brazil. They claim the findings will help us understand cloud formation, chemical differences between natural and polluted environments, and regional and global climate change. Published in the journal Science, the research is an outcome of the EUCAARI ('European integrated project on aerosol cloud climate and air quality interactions') project, which received EUR 10 million under the 'Sustainable development, global change and ecosystems' Thematic area of the EU's Sixth Framework Programme (FP6).

The air above the Amazon rainforest is cleaner than almost anywhere else on earth, thus allowing the team to measure particles emitted or formed within the rainforest ecosystem that are relatively free from the influence of anthropogenic or human activity. The environmental engineers or 'archeologists of the air' hope the study will further their understanding of cloud formation, which affects levels of precipitation and the ability to grow crops and plants, as well as climate change.

'We basically had two "travel" days worth of pure air movement over 1 600 kilometers before the air came to our measurement site,' said lead author Scot Martin, Gordon McKay Professor of Environmental Chemistry at the Harvard School of Engineering and Applied Sciences (SEAS) in the US.

Professor Martin explained that by 'sampling from a 40-metre high tower and using a range of techniques, the researchers detected and imaged atmospheric particles' and found that 'particles in the submicron size regime most relevant to climate could be traced to the atmospheric oxidation of plant emissions, or so-called secondary organic aerosol droplets'.

He described this as 'a kind of liquid organic particle' and said it was the first time that anyone has ever imaged one of these particles in isolation 'because in the northern Hemisphere and other anthropogenic regions, when you collect a particle it is a mess and filled with soot, nitrates, and other pollutants'.

In the pristine Amazon Basin the researchers were able to detect aerosol particle number concentrations of a mere several hundred per cubic centimetre (cm3) - in heavily industrialised cities, particles concentrations are in the tens of thousands per cm3, making it impossible for climate scientists to measure any net change when additional particles, either natural or artificial, are added.

However, it is essential that scientists manage to measure such changes, as Professor Martin highlighted. 'Those particles are affecting cloud formation and cloud formation is affecting precipitation which is affecting the plants,' he said 'This is what we call the great tropical reactor. Everything is connected and in our research we finally had a real glimpse of natural aerosol-cloud interactions'.

Lead co-author Ulrich Pöschl, a scientist at the Max Planck Institute for Chemistry in Germany, said: 'The new insights and data help us and our colleagues to understand and quantify the interdependence of the cycling of aerosols and water in the unperturbed climate system'. He added that 'a thorough understanding of the unperturbed climate system is a prerequisite for reliable modeling and predictions of anthropogenic perturbations and their effects on global change'.

As the Amazon Basin is going through a period of development, co-author Paulo Artaxo, a professor of physics at the University of São Paulo in Brazil, highlighted that scientists will now have an opportunity to watch the influence of human activity on the atmosphere in real time. 'In Brazil, we now have even more solid science to support sustainable development in the Amazonian region,' he noted.

'Looking ahead, we hope to clarify the mechanisms of how vegetation interacts with the atmosphere and elucidate the main natural feedbacks. Doing so will give us a way to monitor atmospheric change accurately in light of ongoing deforestation.'

Pupils plan to buy a bit of the Amazon rainforest: Schools' mission to protect land

Thursday, September 30, 2010

It may be more than 5,000 miles away, but the heart of a reserve in the Amazon rainforest could soon become the property of the people of Hull.

The pioneering initiative, called One Hull Of A Rainforest, will see the city bid to raise £250,000 to help protect the Maquipucuna Reserve from being developed by the Ecuadorian Government.

The initiative is the brainchild of a handful of Hull primary school teachers who visited the reserve at Easter.

The £250,000 will buy 100 hectares – the equivalent of 100 football pitches.

If bought by a foreign owner, the land would be protected from being developed by the government, therefore protecting hundreds of species.

Natasha Dawson, primary development officer for the Humber Education Business Partnership, organised the trip.

She said: "The teachers were moved by what they saw and decided it would be a great idea to start a charity and call it One Hull Of A Rainforest.

"Initially, the project was to involve primary schools in Hull, who would raise money throughout the year.

"However, secondary schools became interested and organisations, including Hull BID and One Hull, and it has grown from there."

The land would be owned by One Hull Of A Rainforest, but managed and protected by the Maquipucuna foundation.

As such, it would be protected from logging or development.

Other cities globally are already looking to follow Hull's lead and it is hoped eventually all 6,000 hectares of the reserve will be protected.

Nigel Marshall, a teacher at Gillshill Primary School in Cavendish Road, who went on the trip, said: "One Hull Of A Rainforest will provide a wonderful opportunity for the children of Hull to understand the importance of the rainforest to the world we live in."

The fundraising launch will take place at the Freedom Centre in Preston Road, east Hull, on October 15.

Twelve pupils will also have the chance to visit the land they are purchasing to lay a plaque inscribed with the names of all the schools, businesses and other organisations that have fundraised to buy it.

British Missionary and Eco-Activist Fights Expulsion from Peru

September 30, 2010
Source: Environment News Service


Nearly three months after Peru's immigration department informed British educator and Catholic De La Salle brother Paul McAuley that his residency had been revoked, he remains active in the defense of the country's rainforests and native peoples.

Yet despite a court victory and support from local religious and indigenous leaders, various environmental organizations and Amnesty International, McAuley's lawyer said that Peru's Interior Ministry has not abandoned its efforts to deport him.

"The state's persecution of Brother Paul continues," said attorney Rita Ruck, who represents the Catholic Church's apostolic vicariate of Iquitos, the Amazon River port where McAuley lives.

The Immigration Department cancelled McAuley residency in late June on the grounds that he had engaged in politics and activities that threatened the public order.

When the Catholic Church's lawyers appealed the decision, however, the Interior Ministry failed to prove that McAuley had violated immigration law and a judge halted his expulsion.

Ruck explained that since then, local immigration officials have simply refused to renew McAuley's residency card, which expired on September 21. She said that most of the Catholic clergy in Iquitos are foreigners who renew their residency every year, a process that usually takes a few hours.

"They've come up with a hundred excuses not to renew Brother Paul's residency," she said.

Born in Portsmouth, England and educated at Oxford, McAuley taught in rural Nigeria and ran teacher trainings in Rome before moving to Peru in 1990. He helped build and run a school in a shantytown in the desert north of Lima before moving to Iquitos, in Peru's lush northeastern lowlands, in 2000.

McAuley explained that his education work in Iquitos included trips to indigenous communities scattered through the surrounding rainforest, where he witnessed the impact of logging and oil exploitation on the region's natural resources and native peoples.

During the past decade, Peru's government has facilitated an expansion of oil exploration and logging in the country's portion of the Amazon Basin - the second largest slice of that vast wilderness after Brazil's - more than half of which has been divided into oil concessions.

In 2005, McAuley and several former students founded the Red Ambiental Loretano, or Loreto Environmental Network, to educate the region's indigenous inhabitants about threats to their forests, rivers and livelihoods.

Though its focus is environmental education, the organization presented a legal motion that forced the government to release the results of a Ministry of Health study documenting high levels of lead and cadmium in the blood of Indians living along the Corrientes River, into which oil companies dumped contaminated production waters for years.

Another legal case filed by the organization resulted in a ban on logging in the Mazan River Basin, which loggers have since defied.

McAuley said he believes the attempt to deport him stems from his recent efforts to educate local people about the forestry law currently being debated in the Peruvian congress, which he claims would allow the concentration of vast tracts of rain forest in few hands, among other problems.

The administration of President Alan Garcia drafted the law to replace one that was repealed last year following a 10-week indigenous mobilization against nine laws that native leaders said threatened their land rights and natural resources.

That largely peaceful protest turned violent when police stormed a highway blockade in Bagua province, launching two days of bloodshed that left 200 injured and 34 dead.

President Garcia insisted that the laws posed no threat to the Amazon's native peoples and claimed that their leaders had been deceived by outside agitators. Garcia's Chief of Staff, Javier Velasquez, called McAuley an agitator when reporters asked him about the case in July.

McAuley explained that his environmental work grew out of his religious vocation and cited a declaration of the Latin American Bishops Conference that calls upon members of the Catholic Church to help communities that are threatened by the destruction of the natural resources they depend on.

McAuley is one of several Catholic priests and bishops who have been threatened with deportation because of their work on behalf of the environment, or indigenous communities.

Five leaders of Peru's principal Amazonian indigenous organization, the Peruvian Rainforest Inter-Ethnic Development Association, AIDESEP, are also fighting charges of fomenting sedition and riots filed during the last year's protest.

Ruck said she believes Peru's Interior Ministry is working on a second case against McAuley, who received a summons last week. She explained that the summons was a violation of due process, since he hasn't been charged with anything, so she responded by filing another writ of habeas corpus.

Ruck noted that McAuley has received widespread support within the church and the community since his immigration troubles began, citing a march in Iquitos in July that "stretched for 10 city blocks."

Two indigenous groups have offered McAuley sanctuary in their territories to save him from deportation, but he said he wouldn't consider accepting their offers.

"I won't break the law," he said. "What we have been saying all along is that we want the jungle to be treated according to national and international law."

Eyes open in the Amazon

Sep. 20, 2010
Source: NCR Online


IQUITOS, PERU -- On a steamy Sunday afternoon, Br. Paul McAuley huddled in a thatched-roof shelter with a group of college students from remote indigenous communities. The promised government meal subsidy had not arrived, and the students were out of food. There had been no breakfast or lunch that day, and there was no money for dinner.

Their urgent need temporarily eclipsed the threat hanging over McAuley, who has been their adviser, supporter and friend for the past decade. A month earlier, Peruvian immigration officials had announced that they were revoking his visa, accusing him of disturbing the peace. Although he had won a stay, McAuley, a De La Salle brother from England, did not know if he would be around long enough to see the young people graduate.

The students had rallied round, taking to the streets to urge the government to rescind its order.

“We’re standing up for him as we would for another indigenous person,” said Rogelio Necca, 22, a Matsés student. “We don’t want Brother Paul to leave.”

Slight and soft-spoken, with gray hair and glasses, McAuley doesn’t fit the mold of an agitator. But he has a steely resolve that made the desert bloom around a school in a Lima shantytown where he was principal in the 1990s.

In Peru’s Loreto Region, a vast swath of rainforest in the northeastern corner of the country, he is determined to help indigenous communities learn to defend their rights and stave off threats to the forest and rivers on which their lives and livelihoods depend.

And that, apparently, has annoyed some authorities.

“We were doing a campaign slowly and quietly about the dangers of a couple of parts of the [proposed new] forestry law, and I suspect that touched a nerve,” McAuley said.

Peru’s use of its natural resources is contentious. With annual growth of up to 10 percent in the past decade, the country was touted as Latin America’s answer to the Asian tigers. Instead of high-tech industries, however, the export of raw materials drives the economy.

The story is familiar around Iquitos, a once-opulent town carved out of the tropical forest by rubber barons who enslaved or relocated entire populations of indigenous people to work on the plantations. Now timber, oil and gas have replaced rub-ber as the region’s export commodities. Three-quarters of the Peruvian Amazon is divided into concessions that overlap hundreds of indigenous communities.

Indigenous students who arrive in Iquitos -- after growing up in open-sided, thatched-roof dwellings in villages with no electricity, connected only by rivers -- step into an alternate reality.

When he moved to Iquitos from Lima in 2000, McAuley said, “I was totally ignorant of what the jungle was about.” He began working with the young people, helping them organize, find living quarters and negotiate a food subsidy with the regional government and “opening their eyes to the global reality.” He visited their remote communities, learning about the “complete [government] neglect,” pollution from oil drilling and other threats to the forest and rivers on which the indigenous people depend for survival.

It was, he said, “a huge field for education.”

Some students are a two- or three-week trip by river from their homes, without cash for rent, books, photocopies or school supplies. “Their families can’t send them money,” said McAuley, who arranged for about 30 youths to live in traditional-style dwellings on the grounds of a former De La Salle retreat house in Iquitos.

When McAuley founded the Loreto Environmental Network in 2004, his message of environmental stewardship dovetailed with that of indigenous people’s right to territory, culture and livelihood.

A package of presidential decrees issued in 2009, which indigenous leaders said would make it easier for private companies to strip their lands of natural resources, sparked protests that ended with a violent confrontation in Bagua, in north-central Peru, in June 2009, leaving 34 people dead. Two months later, official papers show, immigration authorities decided to revoke McAuley’s residency, but they did not act until June 30, 2010.

McAuley, who was not involved in the events in Bagua, is one of about half a dozen foreign bishops, priests and religious harassed or threatened with jail or expulsion in the past few years. All are active in issues related to communities, extractive industry and the environment.

Amid the uncertainty, McAuley said, his religious life as a brother witnesses to community and solidarity. His troubles also cast his vow of celibacy in a new light.

Without family obligations, he said, “you’re free -- you can take risks that others can’t take. Others can’t speak out. If they do, they’ll lose their jobs and their families will suffer. It makes sense of religious life.”

Nevertheless, when the deportation threat arose, two women offered to marry him so he could qualify for permanent residency. “I said, ‘It’s a lovely gesture, but it will get me in trouble with my community,’ ” he laughed.

Born in Portsmouth, England, in 1947, the son of an Irish naval officer, McAuley was drawn to the De La Salle Brothers’ community life and teaching vocation. After a stint teaching elementary school and a few years in Nigeria -- where he found himself helping with C-sections at a makeshift hospital -- he moved to the De La Salle house in Rome.

Though far from the grass roots, he encountered the wave of theology and Christian community sweeping from Latin America.

“I understood how we are called to be on the borderline between what we do very well [in teaching] and opening up the next stage -- something that would push education a bit further, overcoming limitations that we’d always accepted,” he said.

In 1990, McAuley traded Rome for a shantytown in the Lima desert, becoming principal of a school where the classrooms were built of straw mats. Determined to create a healthy environment, he made the school an oasis, with trees and a hydroponic garden.

Now, despite the troubles and setbacks, the Amazon has captured McAuley’s heart.

“The frustration makes me work harder,” he said. “I try to be creative, I try to be positive, I try to infect others with my concerns.” And he remains committed to the students. “While there’s one of them that needs help to get through the university and survive,” he said, “it’s worth it.”

Amazon Road Workers Find Ancient Earth Carvings

Road workers in Brazil were preparing to pave a highway through the Amazon rainforest recently, when they made an important archeological discovery -- a series of enormous earth carvings, barely perceptible from the ground. Known as geoglyphs by researchers, these complex geometric designs are thought to have been crafted by ancient civilizations centuries earlier, though their purpose, to this day, remains a mystery.

According to Globo Amazônia, these latest geoglyphs were reported by road technicians who were conducting a geographical survey prior to the paving of highway BR-429, a road which cuts through the state of Rondonia in the Brazilian Amazon. Because the carvings are usually quite large, frequently measuring over a mile, they are notoriously difficult to see from ground-level -- so an archaeologist was called in to confirm the discovery.

Francis Pugliese, from Brazil's National Institute of Historical and Artistic Heritage, believes the latest finds are only the tip of the iceberg. "Surely there's more," he said. "It would be necessary to use other technology to locate them."

To date, some 300 geoglyphs have been recorded in the Brazilian Amazon, thanks largely in part to the advances in satellite imagining. Using tools like Google Earth, archaeologists can easily scour the landscape for the sprawling geometric carvings. Deforestation and development in the rainforest, too, has made it possible to find many geoglyphs that would otherwise be hidden from view.

Even though the first geoglyphs were discovered in the region in the 1970s, archaeologists still aren't sure about how they were made or what purpose they served for the people that carved them into the Earth some 700 years ago. Still, the presence of these large-scale geometric figures would seem to indicate that the ancient cultures of the Amazon were far more advanced than previously thought.

Teen evangelists: next stop Iraq

It’s just after 6am and the sun is not yet up. Two hundred children stand in a clearing, surrounded by a dense jungle of palm trees on an island off the Florida coast. A girl of about 15 climbs a stepladder in the middle of the group and everyone bows their heads. 'We pray the Lord will keep us safe today,’ she says.

The children divide into smaller groups and disappear into the forest where, one at a time, they embark on an army-style obstacle course that involves crawling through painted steel tunnels, scrambling over a 20ft mountain of tyres, climbing over huge wooden walls emblazoned with the words 'doubt’, 'anxiety’ and 'confusion’, and then attempting to put large wooden boxes, painted with the books of the Bible, in chronological order.

'Judges, Ruth, where’s 2nd Chronicles?’ shouts a staff member named Linda Maher. 'Psalms. Ecclesiastes!’

This is Teen Missions International, affectionately known as 'The Lord’s Boot Camp’, a sprawling 250-acre slice of jungle on Merritt Island, 45 minutes east of Orlando. Each summer, hundreds of children between the ages of four and 18 descend on this place to sleep in tents, wash themselves and their clothes in muddy lake water (there is no running water or electricity), endure swarms of bloodthirsty mosquitoes, tackle obstacle courses, and – most importantly – learn to evangelise.

Once boot camp is over, the children are flown to far-flung corners of the globe to begin their work as Christian missionaries where they will help build schools and churches, and attempt to convert the people who live there. 'This is not pamper camp,’ Teen Missions’ 82-year-old founder Bob Bland once told an American television crew. 'If you’re looking for pamper camp, that’s down the road.’

Bland set up Teen Missions 40 years ago and in that time 40,000 youngsters have come through here. At the end of this week, the teams will head to places like the Amazon rainforest, Belize, Uganda and Malawi to begin evangelising, work with Aids orphans or expand existing mission buildings.

Eighty million Americans identify themselves as Evangelical Christians, making them the largest religious group in the United States, and while some say missionaries have been a force for good, providing much-needed medical care and education as well as championing the rights of indigenous people, others say the spread of Christianity reeks of colonialism and has obliterated native traditions. But that hasn’t stopped the Teenvangelists – this new breed of young, passionate American bent on spreading their old-time religion.

Bland is unapologetic about the potentially thorny issue of trying to convert people. Evangelism is the underpinning of everything that happens at Teen Missions, although he says there is more than one way to preach the gospel: it’s not just bible thumping, he insists. 'They show by example; by helping people.’

Occasionally, though, spreading the word can be met with hostility: at one of the first boot camps in Indonesia, Bland says the team had rocks thrown at them. 'Some people are anti-whatever,’ he says. 'But now we are operating six Bible schools there, so in time they see you’re real and doing something good. You can’t force anyone to be anything.’

Bland and his team will certainly have their work cut out for them next year, when they plan to visit what could be their most hostile country yet: Iraq.

Back at boot camp, a group is attempting to cross the Slough – a stagnant man-made swamp. 'Praise the Lord,’ one boy yells as he swings across and emerges, wet and muddy, from the smelly water. A girl, Ashley, looks apprehensive as she gets to the edge, grabs hold of the rope and swings but slips, emerging a second later from the water, crying.

'Whoa, you walked across the water,’ another boy yells to his friend as he makes it across.

The Lord’s Boot Camp is nothing if not authentic: on more than one occasion I’m told that if the children can survive this they can survive anything the developing world can throw at them. It’s hot (a scorching 97F/36C while I’m there), humid and a 13ft alligator was removed from the lake that doubles as the children’s swimming pool last summer (there are rumours that smaller ones still lurk under the water). The snapping turtles, however, are still very much there.

Home for the two weeks they’re here is in tents, pitched on wooden pallets and covered with pegged-down sheets of black tarpaulin. There are makeshift washing lines suspended between trees and each child is issued with a five-gallon bucket to collect lake water to flush the lavatories, clean their clothes and themselves.

Teams are given points each day depending on how clean their camp site is: the group that wins the most gets to swim in a bona fide swimming pool (not the lake). Those that lose have to wear placards that say 'I live like a pig’ around their necks and clean the lavatories.

The main gathering area is a huge 'big top’ tent where rallies are held each evening, at which the children sing, pray and listen to sermons. Overlooking that is the 30ft-high prayer tower, which looks not unlike a prison watchtower. Here, for 12 hours each day, children spend one-hour shifts sitting in the top, praying over photos of their fellow missionaries.

Nearby, a group of younger children wearing pyjama bottoms, hard hats and work boots are learning to mix concrete in a clearing among the palms. One of the girls in the group, May Wadman, is just nine years old. She is tiny, wears thick-lensed glasses and her hair sticks to her face with sweat. She has never been out of the US before and tells me she’s excited about going to Malawi.

Her friend, Elena Demos, an 11 year-old from West Springfield, Massachusetts, went there last year. 'We planted fruit and vegetables for the kids at the orphanage, hung out with street children and taught them stories from the Bible,’ she says. 'We made their day.’

Teen Missions estimates that scores of its campers have gone on to become full-time missionaries or work for the church in some capacity.

The main purpose of boot camp, though, is to learn evangelism techniques to employ in the field. Classes take place daily in an office building near the estate entrance. It’s seen better days – there are damp brown patches on the ceiling and peeling paper on the walls. It is, however, the only chance during camp that the children get a break from the intense heat.

Before they begin, a girl leads the group in prayer. 'Please Lord, help us turn the world more Christian,’ she says, before they pair off and practise evangelising.

Sixteen-year-old John Givens says his tactic is usually to sit down and talk to someone as if he’s getting to know them. 'We’re taught to ask big questions,’ he says, 'like: “Do you think you’re a good person?” Then you say: “Good people can’t get into heaven.”’

According to Teen Missions, they’re not good enough.

'I then pull the Ten Commandments on them,’ continues John. 'I tell them that if they tell a lie it’s the same thing as murder in God’s eyes.’

The instructor asks the class if it’s getting easier to articulate their faith. 'Are you fumbling for the right words or the right verses?’ he says. 'Just remember, the best philanthropist in the world doesn’t qualify for eternal life. That includes Gandhi and, what’s her name, Mother Teresa. Not good enough.’ Wow. What chance do the rest of us have?

John, from New Jersey, is the youngest of five children and grew up in a large Christian family. He tells me he’s finding the camp tough. 'It’s physically and mentally challenging. The first few days were awful. I’m a clean person but I haven’t taken a bath for two weeks. It’s hot and humid. I barely get any sleep – I have to lie on my shirt or I’ll stick to my mattress. We bathe with a bucket of lake water – I have found dead fish in my clothes. But it’s a personal challenge and I will finish it,’ he says.

I ask whether he’d send his children here in future. 'If they were p---ing me off,’ he says, laughing.

Amber Tuttle admits Teen Missions isn’t for everyone. Together with her husband, Brian, Tuttle – a pretty woman in her mid-thirties – is leading a group to Peru. 'There may be some here who say they’ll never come back, that’s fine,’ she says. 'It may be a one-time experience, but for some it changes the course of their life.’

Tuttle first heard about Teen Missions in a Christian radio broadcast when she was 11. Three years later she went on her first camp – to Mexico’s Yucatan peninsula. 'Two miles from where we were staying was poverty like I’d never seen,’ she says. 'The church was literally made of twigs and cardboard, and we tore it down and built a concrete block church.’

Tuttle met Brian on another mission trip – to Canada – in 1990, they married and now have three children: Wes, 15, Seth, 13 and Emily, 11. In 2008, the couple decided they wanted to become full-time missionaries. They sold their home and moved into a trailer down the road from the base on Merritt Island, and asked family, friends and their local church to sponsor them. They receive around $2,000 a month to live on.

'We’ll see where the Lord leads us,’ Tuttle says. 'It was hard for Brian as the man. He had a good job, we were out of debt, we had a nice little home, a car, and it was hard to let go of that.’

Bob Bland can be seen most days during boot camp, riding around on his old bicycle. Dressed in a purple polo shirt and jeans, he is tanned, has smartly combed white hair and speaks with a strong Southern drawl. He also looks a lot younger than his 82 years.

Born in Ohio into a farming family, he initially trained as a plumber and carpenter before deciding to go to Bible college. He then worked at a youth ministry for six years, came up with the idea for Teen Missions and bought some land bordering Nasa's Cape Canaveral space centre from the Girl Scouts organisation.

'We didn’t have boot camp to begin with,’ Bland explains. 'We just took ’em into the field. But then the Peru trip happened and everything that could go wrong went wrong.’

'Peru’ has become legend at Teen Missions. Bland says the trip there in the early Seventies was a disaster that involved, among other things, rebellious campers, cancelled flights, getting stuck in the Amazon, near-drownings and deadly snakes. 'Kids could have lost their lives on that trip,’ he tells me. 'So many bad things happened. We needed some training and discipline.’

I ask Bland whether some of the children are really cut out for mixing cement and building schools – especially the younger ones like nine-year-old May, who I’d met earlier, or Elena, whose shovel was taller than she was. But when it comes to Teen Missions, I quickly discover Bland is particularly evangelistic.

'At boot camp we unplug ’em,’ he says. 'There’s so much noise in their lives they can’t hear anything. They got so much junk – iPods and they’re texting and… here it’s all gone. You smuggle a Pepsi in here, you can sell it for 50 bucks on the spot. A lot of kids grow up at boot camp.’

One major criticism levelled at short-term mission trips – let alone ones that involve children as young as nine – is that they really don’t make much impact in the places they go; that the trips are designed to help the missionaries, not the people native to those countries.

Take the Haiti trip next summer, for example. The promotional blurb reads: 'Looking for an unforgettable missions trip in one of the poorest countries in the world?’ That project involves working on a church building and clearing rubble from the pastor’s house.

Bland admits that although they do build schools, churches and orphanages, the main work of Teen Missions is to change the lives of the children that are going on these trips. 'In our leader training seminar, the first thing we tell them is we’re building kids, not buildings,’ he says.

'Are they helping? Yeah, they’re helping, but who are they helping? Are they helping the people there? No, not very much… If it’s a two-week deal it’s pretty much a touristy thing because you’ve got to see the sights and by the time you do that you’re gone. But it does help get them to see there’s another world they’ve never been to, especially if it’s a Third World country. They don’t forget that.’

What about the conflict between the spread of Christianity and local cultures? 'The missionary Marilyn Laszlo, a big name in Christian circles, was just here giving a talk to the kids,’ Bland says. 'She was along the Sepik river in New Guinea and the people there were burying people alive. Are we changing that culture? Yeah – you better believe it.’

I’d earlier asked a group of girls heading to Samoa if they knew much about the island. 'We’re not told much about the countries we go to unless we research it ourselves,’ they said.

Soon, Bland is flying to Iraqi Kurdistan to lay the foundations for a mission trip there next June. The person leading that expedition will be Margaret Watsa, a Canadian who used to teach in England. She’ll be teaching phonetics. 'God has made it very clear to me there is a plan and that I’m part of that plan,’ Watsa tells me. 'I think if I’m supposed to be doing this, he’ll either protect me from harm or it’s his plan that something should happen… I believe my life is in God’s hands.’ Two children have already signed up for the Iraq trip, but Bland says he won’t decide whether it’ll go ahead until he gets back from his recce.

The final evening at boot camp, before the teams fly off to their respective countries to begin the Lord’s work, is known as Commissioning Night. During the day there has been hammering, the clunking of metal and the roar of tractor engines as the children and their team leaders help take down their tents and dismantle the camp.

Several weeks’ worth of dust and forest debris is blown and swept from paths, and teams march around the site carrying buckets, shovels and bags. 'One more day, one more day,’ they shout as they gather in the big top for the final ceremony.

Just outside the marquee, the forest is alive with the shrill hum of crickets. Standing by the obstacle course, kicking dirt up against the 30ft-high boards that, earlier in the week, hundreds of children had leapt over at an ungodly hour, are two boys: Peter Vance, 16, from Massachusetts, and his new friend Austin Carver, 15, from Pennsylvania, are flying to Madagascar in the morning.

Neither of them has enjoyed his time here. Peter says his parents gave him an ultimatum: stay at state school and come to Teen Missions for the summer, or go to a tiny Christian school in the autumn. Teen Missions was the lesser of two evils. 'I grew up as a missionary kid in Uzbekistan for 14 years,’ he says. 'This isn’t such a bad place but the worst thing is not having any technology. I miss my iPod, logging on to Facebook, my Xbox. I miss playing and watching sports.’

Austin is less diplomatic. 'They try to force Jesus on you in every physical way,’ he says. 'We go to church every single day but they only call it church on Sunday. I won’t come back. I want to form a band – I play bass. The music sucks here. My parents paid $5,000 for me to do this.

'Dude, if Pete wasn’t here I don’t know what I’d have done – you’d have seen me hanging from the prayer tower.’

Air archaeologists isolate 'pure' aerosol particles

EU-funded environmental engineers have isolated aerosol particles in near pristine pre-industrial conditions in the remote Amazonian Basin in Brazil. They claim the findings will help us understand cloud formation, chemical differences between natural and polluted environments, and regional and global climate change. Published in the journal Science, the research is an outcome of the EUCAARI ('European integrated project on aerosol cloud climate and air quality interactions') project, which received EUR 10 million under the 'Sustainable development, global change and ecosystems' Thematic area of the EU's Sixth Framework Programme (FP6).

The air above the Amazon rainforest is cleaner than almost anywhere else on earth, thus allowing the team to measure particles emitted or formed within the rainforest ecosystem that are relatively free from the influence of anthropogenic or human activity. The environmental engineers or 'archeologists of the air' hope the study will further their understanding of cloud formation, which affects levels of precipitation and the ability to grow crops and plants, as well as climate change.

'We basically had two "travel" days worth of pure air movement over 1 600 kilometers before the air came to our measurement site,' said lead author Scot Martin, Gordon McKay Professor of Environmental Chemistry at the Harvard School of Engineering and Applied Sciences (SEAS) in the US.

Professor Martin explained that by 'sampling from a 40-metre high tower and using a range of techniques, the researchers detected and imaged atmospheric particles' and found that 'particles in the submicron size regime most relevant to climate could be traced to the atmospheric oxidation of plant emissions, or so-called secondary organic aerosol droplets'.

He described this as 'a kind of liquid organic particle' and said it was the first time that anyone has ever imaged one of these particles in isolation 'because in the northern Hemisphere and other anthropogenic regions, when you collect a particle it is a mess and filled with soot, nitrates, and other pollutants'.

In the pristine Amazon Basin the researchers were able to detect aerosol particle number concentrations of a mere several hundred per cubic metre (cm3) - in heavily industrialised cities, particles concentrations are in the tens of thousands per cm3, making it impossible for climate scientists to measure any net change when additional particles, either natural or artificial, are added.

However, it is essential that scientists manage to measure such changes, as Professor Martin highlighted. 'Those particles are affecting cloud formation and cloud formation is affecting precipitation which is affecting the plants,' he said 'This is what we call the great tropical reactor. Everything is connected and in our research we finally had a real glimpse of natural aerosol-cloud interactions'.

Lead co-author Ulrich Pöschl, a scientist at the Max Plank Institute for Chemistry in Germany, said: 'The new insights and data help us and our colleagues to understand and quantify the interdependence of the cycling of aerosols and water in the unperturbed climate system'. He added that 'a thorough understanding of the unperturbed climate system is a prerequisite for reliable modeling and predictions of anthropogenic perturbations and their effects on global change'.

As the Amazon Basin is going through a period of development, co-author Paulo Artaxo, a professor of physics at the University of São Paulo in Brazil, highlighted that scientists will now have an opportunity to watch the influence of human activity on the atmosphere in real time. 'In Brazil, we now have even more solid science to support sustainable development in the Amazonian region,' he noted.

'Looking ahead, we hope to clarify the mechanisms of how vegetation interacts with the atmosphere and elucidate the main natural feedbacks. Doing so will give us a way to monitor atmospheric change accurately in light of ongoing deforestation.'

Oil: Can Ecuador see past the black stuff?

Tuesday 28 September

One of the most extraordinary people I have met in 10 days of travelling around Peru and Ecuador has been Alberto Acosta. He's head of Ecuador's leading research group now, but until 2007 was the second most powerful man in the country after the president, Rafael Correa. He was not only charged with masterminding the new constitition but was head of the assembly, or parliament, a founder of the ruling political party and minister of energy of the country that depends on oil.

But Acosta will go down in history as the world's only serving oil minister to have ever proposed leaving a country's black stuff in the ground. That's like Dracula renouncing blood, or a sports minister saying it's better to play hide and seek than football. It just does not happen.

He is the architect of the Ecuadorean government's plan to guarantee to leave 965m barrels of oil in the Yasuni national park in eastern Ecuador if the world contributes $100m in the next year and eventually around $3.6bn. The revolutionary economic idea to earn money by not exploiting a resource has been endorsed by the government and will be administered by the UN Development Programme.

Acosta was accused of being crazy by some of his cabinet peers, but is clearly anything but. He's an old oil man, a trained economist and he argues vehemently that it makes political, economic and ecological sense to leave the oil in the ground. He calculates that if the Yasuni oil is drilled, it will earn Ecuador around $7bn. But against that must be put the incalulable cost of climate pollution, of trashing the Amazon rainforest, and of the conflict and devastation it will cause in one of the most diverse regions of the world. In addition, two uncontacted tribes believed to be in the vicinity of the exploration block where the oil has been found will almost certainly be made extinct.

Acosta's thinking is not new but part of a growing body of global evidence for the phenomenom called "resource curse". This is the idea that mineral and oil-rich developing countries stay poor, foster corruption, encourage dictators and trash the environment. From Nigeria to Sudan, and Equatorial Guinea to Gabon, oil has distorted economies and led to trouble and human rights abuses. As the Venezuelan Juan Pablo Alfonso, one of the Opec founders, said: "You will see: oil will bring us ruin … oil is the devil's excrement."

Acosta has written about this in his bestseller La Maldición de la Abundancia (The Curse of Plenty) and he is adamant that Ecuador is in danger of going the same way. "Yes, oil is very important to Ecuador," he told us. "But abundance is bad. We have extracted 4.5bn barrels so far, which provided us with $130bn. We've consumed half our oil and we have about half left. But while it has developed our infrastructure, we have not developed [as a country], or gained full advantage from it. Oil has brought us conflict and [billions of dollars of] environmental destruction; we are transforming the Amazon into a country where climate fluctuations will be terrible. Oil has not solved the problems. We must have a less extractive economy.

"What we need to do in the medium to long-term is overcome this economic model of accumulation. We need another way to organise the economy, which is not so dependent on the exploitation of natural resources. We need to move from an extractive economic model, to one based in the knowledge, and forces, and needs of human beings, individual and collective. We also need another way of inserting ourselves into the world market that is more intelligent than simply providing raw materials.

"In reality, we've been living off the rent of nature. In the last few decades, since the 1970s, Ecuador has had as its principal source of revenue the exploitation of oil – the extraction of crude oil and the export of oil into the international market. Ecuador needs to break with the extreme concentration of assets and income, and change the pattern. We need to achieve equality if there is to be justice and freedom.

"I could see the [oil] monster from the inside. Ecuador is the producer of flowers, oil and bananas but it has never developed. Perhaps we are poor because of our resources. We should be an intelligent country. We cannot live without nature but nature can live without us. We must change our model of life. What about [Yasuni becoming] a sanctuary for nature, for humanity?"

The race is now on. If Ecuador attracts $100m for Yasuni within the year, the oil will not be extracted. If it does not, then almost certainly President Correa, Acosta's old friend, will almost certainly say that he has no option but to send in a Chinese oil company to extract it. It will be the end of the two uncontacted tribes and a vast swathe of the most diverse forest in the world.

Above all, however, it will be a tragedy for the world because the only country which has had the chance to reject the extractive development path and demonstrate what is possible, will have blown it.

Future looks bleak for the Amazon rainforest

Monday, 27 September 2010
Source: Colombia Reports


With 2,000 square kilometers of forest destroyed every year, the future of the Amazon rainforest in Colombia appears bleak, reports Colombian newspaper El Espectador.

The forest, known as the "lungs of the world," is home to 79 endangered species and 44 indigenous cultures threatened by migration. The spraying of chemicals to stop coca production has also destroyed a great deal of flora. Drug trafficking, urbanization, mining, changes in farming techniques, and timber production have all been fingered as causes of deforestation, and the threat appears to be growing, according to the newspaper.

El Espectador called on the Colombian people and government to "stop giving away the Amazon," which it says will disappear by 2030 if nothing is done to stop deforestation. The Amazon covers 35% of Colombia's territory, and accounts for 61% of the country's forest.

"Amazonas 2030" is an organization comprised of media companies, civil society groups, and businesses which coordinate to monitor and evaluate changes in the rainforest. Wendy Arenas, director of Alisas, a member organization of Amazonas 2030, argued that the issue must be prioritized, "Now is the time for someone to ask the government about the Amazon."

El Espectador praised the work of the organization, but said there was a need for an increased respect for the rainforest among Colombian people, and for more decisive action by the government.

Savannah being destroyed by farming

In its drive to become the world leader in agriculture, Brazil is sacrificing a vast stretch of savannah

IN THE waters around the Amazonian port of Santarém fishing is just a matter of casting one’s net and hauling in another bounteous catch from the world’s mightiest river.

Even so, times are hard for local fisherman Anselmo Cardoso who now rarely goes out and when he does often has to dump his catch because he cannot find a buyer, despite slashing prices down to his costs.

“There are just too many people these days trying to live off fishing. Many who had to give up logging took it up because in these waters it is easy,” he says.

Cardoso should know as he is one of this new generation of fishermen. For 25 years he ran a restaurant serving up hearty portions of fish stew, rice and manioc to loggers on Marajó, an island half the size of Ireland in the mouth of the Amazon, several days’ boat journey downriver.

“But then the government came and ended the logging industry. First they shut down the illegal lumber mills and then they stopped renewing environmental permits for most of the legal ones,” he says.

“Overnight they ended the whole timber culture.”

He headed back to his hometown and invested his savings in a new boat, the Halley II , but too many others left jobless by the logging crackdown had the same idea.

“It is right to protect the rainforest but we are in this richest of regions and we live in poverty,” he says ruefully.

Stories such as Cardoso’s heard across the Brazilian Amazon are testimony to a dramatic turn in the region’s history. For decades a great migratory wave of miners, loggers and farmers cleared large swathes of the world’s biggest rainforest giving birth to wild boom towns and sparking international fears that the destruction of the world’s green lung would accelerate global warming.

But three years ago the government of President Luiz Inácio Lula da Silva called a halt. The rate of deforestation has collapsed while the amount of timber extracted from the region has halved in the last five years.

“It is early in this process and there are still regions of concern but there are reasons to be optimistic,” says Raquel Carvalho of Greenpeace’s Amazon campaign.

Despite the cautious optimism about the Amazon’s prospects, many environmentalists are still reluctant to give Lula’s government a green seal of approval. The reason lies to the south of the rainforest in a region called the cerrado – the Brazilian savannah.

Covering over a fifth of the country, this vast region is being destroyed at over twice the rate of the Amazon by the inexorable expansion of Brazil’s world-beating agricultural industry. In the cerrado the agribusiness sector faces few of the environmental restrictions now in place to protect the rainforest.

By law, landowners in the Amazon must preserve between 50 and 80 per cent of their property as native forest. In the cerrado this requirement is no higher than 35 per cent and often as low as 20 per cent.

While Lula’s government has clamped down on large-scale farming in the Amazon it has provided cheap credit, technical expertise and other incentives for those pushing ever deeper into the cerrado.

Brazil’s government has sought to reassure the international community that the Amazon will not be affected by the country’s rise to become the world’s leading agricultural superpower by pointing out the expansion of the farming frontier is occurring in the cerrado. But this brings little reassurance to those worried about Brazil’s carbon emissions, largely the result of deforestation.

“The importance of the cerrado as a carbon store is greatly underestimated because much of it is underground,” says Isabel Figueiredo of the Institute of Society, Population and Nature, a Brazilian organisation campaigning to protect the cerrado.

“The native flora has very deep roots. As the cerrado is being cleared at over twice the rate of the rainforest it is possible that carbon emissions from its destruction are equal to or greater than those in the Amazon.”

And what happens in the cerrado will, environmentalists warn, have a negative impact even on a preserved rainforest. With the savannah’s scrub forest and thick grasses being cleared to make way for soy, cotton and eucalyptus plantations the soil’s ability to absorb water and hold it is being compromised causing flooding in the rainy season and increasing drought in the dry months with dire consequences.

“The levels of humidity in the air in the cerrado are important for rainfall in the Amazon. Deforestation in the cerrado will affect the amount of rain in the rainforest. Also, important tributaries of the Amazon river rise in the cerrado and if you have less water flowing into the Amazon you will obviously affect the rainforest,” warns Figueiredo.

The rapid expansion of agriculture into the cerrado under the Lula administration has disappointed not just environmentalists but also land reform campaigners. In opposition Lula’s Workers Party vowed to tackle the country’s unequal land settlement, winning it the backing of the country’s land reform campaign, the biggest social movement in South America.

But in power the hopes of land reformers have been disappointed with the progress of settling the landless peasant little improved under the Lula administration.

“We had hoped for a country where land would not just be a commodity but would also have a social function. But Lula’s agricultural policy has not been for peasants but instead about producing grains for export,” says Dirceu Fumagalli, national co-ordinator of the Pastoral Land Commission, a land reform organisation linked to the Catholic Church.

The expansion of agriculture into the cerrado has largely come in the shape of huge holdings often made up of thousands of hectares owned by investors from other regions in Brazil who provide limited local employment. While the Lula administration has directed more money to assist traditional family farming the amount is just one-fifteenth of that handed over to the agribusiness sector, says Fumagalli.

Rural regions are overrepresented in Brazil’s congress and the farming caucus is powerful. Flush with funds from the farming boom it expects to be further strengthened in Sunday’s election leaving environmental campaigners worried about renewed assaults on the few restrictions in place to protect regions like the cerrado.

Of the three leading candidates running to replace Lula only Marina Silva has placed the environment at the heart of her election campaign by calling for a rethink of Brazil’s agricultural policy. But at 10 per cent in the polls she has little chance of winning.

The two frontrunners, Dilma Rousseff of the Workers’ Party and José Serra of the opposition Social Democrats, are both development-minded economists who analysts say are unlikely to impede the expansion of one of Brazil’s main export industries.

So while recent years have seen great strides in preserving the rainforest the prospects are bleak for the cerrado with some estimates predicting Brazil’s native savannah will have largely been replaced by agriculture by 2030.

“The rainforest awakens the imagination of people while the threat to the cerrado is little reported,” says Figueiredo.

“It is very difficult to be the cerrado in a country that has the Amazon rainforest.”

The Team kit used by Team Sky during the Tour of Britain, alongside Bradley Wiggin's Pinnarello Dogma, is to be auctioned off with all proceeds going to the Sky and WWF chairty link up - Sky Rainforest Rescue.

At this year’s Tour of Britain, Team Sky the UK’s only Pro Tour Cycling Team changed their colours from blue to green to raise awareness of Sky Rainforest Rescue – a three year partnership between Sky and WWF to help save a billion trees in the Amazon rainforest. The Team Sky Rainforest Rescue kit used by the team during the race is now being auctioned off on Going Going Bike.

100 per cent of all winning bids will go directly to Sky Rainforest Rescue as Going Going Bike have waived any charges.

Further to this Sky will match every donation made £1 for £1, to help reach the combined campaign total of £4million.

Deforestation is now responsible for roughly 15 per cent of global greenhouse gas emissions and an area the size of three football pitches is destroyed every minute in the Amazon.

As well as Bradley’s limited addition Team Sky Rainforest Rescue bike, with limited edition green apparel and accessories, including a bespoke Bradley Wiggins Prologo saddle, a Kask helmet, a signed adidas jersey, an adidas cap and two Elite Gatorade bottles, you can also bid for other replica items of kit worn by the whole team. This includes green Oakley Jawbone sunglasses, Kask helmet and adidas jerseys. None of these items are available to buy in the shops.

You've discovered a whacky wood-eating catfish? So what's new?

Monday 27 September 2010
Source: guardian.co.uk


The press has recently been abuzz with news of a newly discovered species of catfish that eats wood, of all things. But since at least the 1990s, scientists have known that some catfish species consume wood. The news stories I have read haven't done a particularly good job of describing why journalists are so intrigued by this discovery, beyond the obvious twist: a fish that eats wood.

But these fish are popular pets: If you look at the tropical fishes available for sale in your local pet shop, then you have probably seen at least one of the dozen or so species that are placed into the genus, Panaque. (For example, today in my local pet shop, there were three Panaque species - all coyly hiding under submerged bits of wood, so I couldn't get a decent photograph to share with you.)

The wood-eating Royal Panaque, Panaque nigrolineatus, is a popular aquarium fish. [Image: Akwa02/Wikipedia; 8 July 2005]

Panaque are medium to large freshwater fish that are placed in the taxonomic family Loricariidae, a large group of catfishes that are united by several common characteristics: their powerful suckermouths and the tough plates covering their bodies. Whilst Loricariidae are found throughout tropical and subtropical rivers in Central and South America, the Panaque, which are the wood-eating specialists in the family, appear to be limited to the Magdalena, Orinoco and Amazon River basins.

These fish go by a number of names. The genus name "Panaque" (pronounced "pan ack" in Britain and Europe, and as either "pan aki" or "pan a kay" in America), is the Latinisation of a native Venezuelan name for these fish. The local indigenous people, the Sharanahua, call it Ishgunmahuan - "large armored catfish."

Indeed, the Sharanahua are quite familiar with this new Panaque species, because it is a popular item on the menu.

The fish, which can reach 70cm (2ft 3in) in length, can be located by characteristic rasping sounds produced when they chew on submerged wood.

A smiling Dr Paulo Petry holds his big fish, Panaque species, netted in summer 2010 by Peruvian biologist Roberto Quispe at the confluence of the Alto Purús and Curanja Rivers on the Fitzgerald Arch, a remote region of the Peruvian Amazon. [Image courtesy of Paulo Petry].

"They seem to be really tough to find and catch. You have to catch them with gill nets or cast nets, or shoot them," explained Paulo Petry, who is formally describing the new species for science based on three individual fish that he and his colleague, Peruvian biologist Roberto Quispe, captured.

"Since they eat wood, you're not going to catch them with a line."

Dr Petry, a zoology professor at Harvard University is also the Nature Conservancy's freshwater specialist for Latin America. During this past summer, Dr Petry was part of a scientific expedition to one of the remotest places on the Amazon River; the Fitzgerald Arch, located in Peru. The trip was sponsored by the US National Science Foundation and took place between 21 July and 3 August.

"Right now, it's fairly isolated there," said Dr Petry. "There are just two flights a month there from [the] Peruvian Air Force to provide supplies. The other way to get in is by river, which is a very long way. We chartered a flight in there, flying over the most pristine rainforest you will ever see."

Even though this species of Panaque had been previously known only from dried pieces of several specimens that the locals captured, this was the first time that live specimens had been captured and studied by scientists.

"The particular specimens that we captured are the first that are fresh specimens, so we have the entire fish from which to take tissue samples," said Dr Petry, thereby allowing scientists to formally describe the species.

"The formal complete description of this species will be published in December in the Copeia magazine," Dr Petry added.

That description will no doubt carefully document one of the features that is unique to the Panaque: their teeth.

Even though it is common for the 700+ species of armoured catfishes to suck organic material -- such as insect larvae, algae, microbes and detritus -- from the surfaces of submerged objects, actually ingesting wood is apparently unique to Panaque. Thus, these fish evolved special "spoon-shaped teeth" especially for this job (see electron micrographs in top right and lower left panels in the figure below).


But how did such a unique diet evolve in fish? Xylivory -- wood-eating -- likely evolved due to competition with other catfish species for food in the Amazon Basin rivers, said the researchers.

Ecophysiologist Donovan German, who did not participate in the expedition, provided additional insight. Dr German is a postdoctoral researcher at the University of California at Irvine, but while a graduate student in biology at the University of Florida, he studied the digestive physiology of wood-eating catfish.

These fish are not strong swimmers so they have to attach themselves to a solid object with their powerful sucking mouth to avoid being washed downstream.

"There're not a lot of rocks in the Amazonian Basin, where these fishes live," explained Dr German. "There's mud and water, and the one consistent substrate at the bottom is wood. It's [also] the one place where fish can go to get food off a surface."

But are Panaque species true xylivores -- are they actually digesting the wood they consume, as do beavers, porcupines and termites?

The same question occurred to Dr German while he was in graduate school. To better understand the structure and function of the gastrointestinal (GI) tracts of wood-eating catfishes, Mr German conducted a series of comparisons between the intestinal structure of wild-caught Panaque and a closely-related species detritus-feeding fish that does not consume wood.

In short, Mr German found that Panaque digestive tracts are similar in shape and size to those of detritivorous fish. Panaque had none of the special anatomical features that other wood-eating animals possess for providing a home for beneficial bacteria that break down wood so the fish may then absorb the nutrients. [DOI: 10.1007/s00360-009-0381-1]

"People think they must have an amazing consortium of microbes in their guts to help the fish digest wood, but that isn't really what I've found," Dr German pointed out.

Earlier work that attempted to isolate gut microbes and identify digestive enzymes that break down various components of wood provided ambiguous results. [DOI: 10.1111/j.1095-8649.1999.tb00858.x]

The other key factor suggesting that Panaque probably do not digest wood is their rapid gut transit time, which reduces the numbers of wood-digesting bacteria that can reside in their intestinal tract.

"The fish pass wood through their guts in less than four hours, which is incredibly fast for an animal that supposedly digests wood," remarked Dr German.

Wood-digesting animals typically retain wood in their GI-tracts for longer than 24 hours.

At this time, it is thought that wood-eating catfish are not digesting wood at all but, by chewing up rotting wood into tiny pieces, they are digesting the organic matter, microbes, and microbial byproducts that reside in the spaces between wood fibers. The wood itself is excreted as waste.

"The amazing microbes are in the river, on the wood itself."

Due to their feeding behavior, Panaque catfishes appear to play a valuable role in the ecology of the Amazonian rainforest. By reducing large chunks of wood into microscopic fragments they are speeding up the process of decay and carbon recycling within the environment.

According to Dr Petry, these fish are found in an area that is filled-to-bursting with biodiversity -- a poorly-known area that is under threat from development.

"There are several proposed infrastructure development projects and roads -- with them will come lumber extraction, cattle ranching and slash-and-burn agriculture," stated Dr Petry. He also noted that on average, over 100 new fish species are discovered every year in South America. This year alone, 69 new species have been described thus far.

"These numbers show very clearly that we are far from knowing the number of freshwater species in South America."

This makes me wonder how many species will disappear before we even know they are there? And how will this loss of biodiversity affect these ecosystems?

From tree choppers to tree huggers Global effort is saving forests, but not fast enough

September 27, 2010
Source: Edmonton Journal

The summer dry season, now drawing to an end, is when the Amazon rainforest gets cut and burned. The smoke this causes can often be seen from space. But not this year. Brazil's deforestation rate has dropped astoundingly fast. In 2004, some 2.8 million hectares of the Amazon were razed; last year only around 750,000 hectares were. This progress is not isolated. Many of the world's biggest clearers of trees have started to hug them. In the past decade, according to the UN, nearly eight million hectares of forest a year were allowed to regrow or were planted anew.

This was mostly in richer places, such as North America and Europe, where dwindling rural populations have taken the pressure off forestland. But a couple of big poorer countries, notably China, have launched huge tree-planting schemes in a bid to prevent deforestation-related environmental disasters. Even in tropical countries, where most deforestation takes place, Brazil is not alone in becoming more reluctant to chop down trees.

The progress in recent years shows mankind isn't doomed to strip the planet of its forest cover. But the transition from tree chopper to tree hugger isn't happening fast enough. In the past decade, the UN says, 13 million hectares of forest -- an area the size of England -- was converted each year to other uses, mostly agriculture. If the world is to keep the protective covering that helps it breathe, waters its crops, keeps it cool and nurtures its biodiversity, it will have to move fast.

For at least 10,000 years, since the ice last retreated and forests took back the Earth, people have destroyed them. In medieval Europe, an exploding population and hard-working monks put paid to perhaps half its temperate oak and beech woods -- usually to clear space for crops. Some 100 million hectares of American forests went in the 19th century, an arboreal slaughter reinforced by a belief in the godliness of "improving" the land. That spirit survives. It is no coincidence that George W. Bush, one of America's more God-fearing presidents, relaxed by clearing brush.

In most rich countries the pressure on forests has eased. But in many tropical ones -- home to around half the remaining forest, including the planet's rainforest girdle -- the demand for land is growing as populations rise. In Congo, which has more rainforest than any country except Brazil, the clearance is mostly driven by smallholders, whose number is about to double. Rising global demand for food and biofuels adds to the heat. So will climate change. That may already be happening in Canada, where recent warm winters have unleashed a plague of pine beetles, and in Australia, whose forests have been devastated by drought and forest fires.

Clearing forests may enrich those who are doing it, but over the long run it impoverishes the planet as a whole. Rainforests are an important prop to continental water cycles. Losing the Amazon rainforest could reduce rainfall across the Americas, with potentially dire consequences for farmers as far away as Texas. By regulating run-off, trees help guarantee water supplies and prevent natural disasters, like landslides and floods. Losing the rainforest would mean losing millions of species; forests contain 80 per cent of terrestrial biodiversity.

And for those concerned about climate change, forests contain twice as much carbon as the atmosphere, in plant matter and the soils they cover. When they are razed and their soils disturbed, most of it is emitted. If the Amazon went up in smoke, it would spew out more than a decade's worth of fossil-fuel emissions.

Economic development both causes deforestation and slows it. In the early stages of development people destroy forests for a meagre living. Globalization is speeding up the process by boosting the demand for agricultural goods produced in tropical countries. At the same time, as people in emerging countries become more prosperous, they start thinking about issues beyond their family's welfare; their governments begin to pass and slowly enforce laws to conserve the environment. Trade can also allow the greener concerns of rich-world consumers to influence developing-world producers.

The transition from clearing to protecting, however, is occurring too slowly. The main international effort to speed it up is an idea known as REDD (Reducing Emissions from Deforestation and Forest Degradation), which pays people in developing countries to leave trees standing. This is not an outlandish concept. It is increasingly common for governments and companies to pay for forest and other ecosystem services. To protect its watershed, New York pays farmers in the Catskills not to develop their land. REDD aspires to do this on a much larger scale.

The only notable success of the Copenhagen climate-change conference last year was a commitment to pursue these schemes. Half a dozen rich countries, including Norway, America and Britain, have promised $4.5 billion for starters. The difficulties are immense. REDD projects will be effective only in places where the government sort of works, and the tropical countries with the most important forests include some of the world's worst-run places. Yet with sufficient attention to monitoring, verification and, crucially, making sure the cash goes to the people who can actually protect the forest, REDD could work. That will cost much more than has so far been pledged.

The most obvious source of extra cash is the carbon market, or preferably a carbon tax. Since saving forests is often the cheapest way to tackle carbon emissions, funding it this way makes sense. With global climate-change negotiations foundering, the prospects of raising cash for REDD that way look poor. But the money must be found from somewhere. Without a serious effort to solve this problem, the risk from climate change will be vastly increased and the planet will lose one of its most valuable and beautiful assets. That would be a tragedy.

Is Brazil’s Sustainable Development Really Sustainable?

September 26, 2010

Sustainable development seems to have left the realms of institutional debate in Brazil and has emerged into a reality for businesses to remain competitive in their markets.

It is also being used as a tool to stimulate the country’s economic growth.

A notable example of this is hydroelectricity, as the country has strived for many years to generate electricity in innovative ways, rather than relying on the use of fossil fuels. Companies are also voluntarily signing up and engaging in Brazil’s GHG Protocol Program with a view to reduce carbon emissions and businesses large and small are leading on sustainable business practices.

While Brazil has received a lot of respect for this forward thinking approach to sustainability, they have also been heavily criticized for hydro projects since the 1980s; in recent months the target has notably been the decision to move forward with the plan to build 3 dams on the Xingu River, which lies in the Amazon Basin.

The most infamous now and the principle one, ‘Belo Monte’, will continue Brazil’s provision of hydroelectric energy, but will also potentially turn tributaries of the world's largest river into 'an endless series of stagnant reservoirs', explains the new short film released by Amazon Watch and International Rivers, narrated by Sigourney Weaver. The film is made via a Google Earth 3-D tour and reveals the potential impact of the dam, as well as the consequences for the indigenous peoples in the area.

“Their way of life will disappear," said the actress.

Hydroelectricity provides 80 per cent of the power that Brazil generates and Belo Monte will generate a further 11,000 MW and will be the third largest dam in the world, adding almost 20 per cent to Brazil’s electric power capacity. Indigenous tribes, as well as environmentalists, have protested strongly against the project for over 30 years. Belo Monte’s reservoirs threaten to flood 668 square kilometers, push more than 20,000 people out of their homes and reduce the flow of the Xingu to merely a trickle during parts of the year. Water supplies will be put at risk; endangering people and animal species, as fish migrations will be blocked causing devastating consequences for the local fisheries that depend on the river for their subsistence and the aquatic creatures within the river that depend on it for the survival of their species.

It is difficult to comprehend how unrest around such a massive project could be disregarded, enough so that the project has been allowed to proceed to this stage, for such a long stretch of time. As far back as 1989, a Kayapó woman warrior held her machete to the face of José Antônio Muniz Lopes, who was the president of the state electricity company that holds the contract today, Eletrobrás. Her drastic measures were emphasis of the indigenous tribes’ fear around the dam being built and those fears have continued and have grown to this day and are now supported by many environmental organizations, as well as the Brazilian people.

It is hard to imagine the extent of the damage building the dam will do when you haven’t stood yourself in the Amazon and seen her beauty and magnitude and seen how the people and the animals live interdependent with her forest’s lush green; words fail to encapsulate it also. Thousands of tiny and large rivers run through the forest and water is a major part of the ecosystem itself which is why if the Belo Monte project is undertaken, it will be a disaster. Building this series of dams is considered to be a key turning point for the Amazon and not in a positive way – it will be the end of life as they know it now for the thousands of people and species living there and the beginning of many more projects like Belo Monte as Brazil tries to meet the energy demands of its country in an economic way. The flooding of the forest to accommodate the dam will provoke a massive release of methane from the vegetation rotting beneath it, millions of years worth of a stored greenhouse gas 25 times more potent thanCO2 and the risk of malaria in surrounding areas will increase also as the insects are attracted to the stagnant water. If past experience of dam projects in the Amazon is any model, Belo Monte will give local people no other choice but to join the many loggers already active in the Amazon, as they can no longer earn income from fishing or their traditional livelihoods like hunting, which will contribute to further large-scale devastating deforestation.

This development cannot be considered sustainable if you add to this the introduction of electricity grids, transmission lines and access roads that will put further pressure on this precious rainforest.

The Amazon’s lesser known sister forest, the Atlantic has already suffered similar destruction, caused by human development, in fact there is only 7% of this precious forest left. In spite of this, it is one of the five richest forests in the world as well as being one of the most highly threatened. What makes the Atlantic forest so special is its biodiversity – in terms of plants and birds and animals, especially primates and amphibians. It is distinguished from many other forests by the high levels of endemicity – species that are only here, and nowhere else. It has maybe 20,000 plant species of which about 6,000 are endemic, for example, of the Atlantic forest’s 25 primate species, 20 are endemic and 14 threatened with extinction. As for its struggle for existence, it didn’t really become a cause until about 30 years ago, long after people had been expressing concern about the destruction of the Amazon. Many people simply didn’t see it, because it didn’t feature in the news: there was not a lot of research on what it holds, even now, and around it being the biggest center of population in Brazil – nearly all of its people live in the Atlantic Forest. Two people in particular are battling hard for its survival.

Robin Le Breton and his wife, Binka, are well accustomed with the notion of ‘sustainable development’. They are Directors of a Research Center in a little town called Rosário da Limeira, in the south-east of the state of Minas Gerais.

I spent a month working with Robin and Binka in January this year, within the beautiful Brazilian Atlantic Rainforest, known locally as the Mata Atlântica and every day since my thoughts around the subject of what can be considered sustainable have dramatically changed. The environment in which they live is typical of many others throughout this breathtaking forest, degraded through the development of agriculture to meet the country and the world’s needs for coffee, amongst other things.

Their research focuses on two things: sustainable land management technology to ensure the future of this forest and its people and the development of alternative products from the forest’s land that can generate income for them and provide an incentive for forest conservation in Brazil.

The Belo Monte dam does not directly impact upon the Atlantic rainforest, but the whole subject does give rise to questions regarding the sustainability of this form of generating electricity and I wanted to know what this incredible couple, who have devoted the last 10 years of their life working to protect what is left of the Atlantic think about hydroelectricity.

Do they feel that it is sustainable? Or, is it an example of a positive idea born out of needing to do things in a different way, which hasn’t been thought through thoroughly enough. Or are there wider implications, considering the project is being driven by the Brazilian Government.

I also wanted to know what he thought the impact of climate change would be upon the long term future of the dams, considering our unpredictable climate and the predicted population rise anticipated for the years to come. The Intergovernmental Panel on Climate Change (IPCC) has predicted a devastating range of impacts from climate change upon Brazil, including an increase in the intensity and number of extreme weather events. The region’s huge geographical diversity means that patterns of vulnerability to climate change are extremely varied, which admittedly also makes modeling difficult, but the possibility of less rain can’t be ruled out and would affect Brazil’s capability to generate electricity via hydropower and would also impact supplies of drinking water compared with demand. Will all the destruction planned for the short-term prove to be a waste in the long-term?

Ice retreat threatens Arctic mammals

As the Arctic melts due to climate change, its iconic marine mammals are feeling the heat. The Arctic Ocean held less sea ice in June of this year than any previous June on record. For the last four summers, the ice melt has exceeded what even pessimistic climate models predicted only a few years ago.

Yet ice and its inhabitants define this region: take away the ice, take away the Arctic. Without wildlife conservation measures and a serious attempt to address climate change, the adverse impacts will only grow.

Between 1979 and 2000, the Arctic held an average of seven million square kilometers of sea ice even in late summer. In 2007, only 4.3 million square kilometers of ice remained, meaning that 40 percent of this habitat was lost. By comparison, about 20 per cent of the Amazon rainforest has been destroyed by clear-cutting—an environmental tragedy that has been widely covered.

Changes this large impose consequences. Since prehistoric times, up to 250,000 walrus have moved northward each summer into the Chukchi Sea, following retreating sea ice. There, off the northern coast of Alaska, walrus feed on clams in the seabed, resting on ice between their dives. Female walrus nurse their young on the ice floes. When the ice rapidly disappeared there during the summer of 2007, thousands of walrus were forced onto land where they risked trampling deaths, predation by bears and depletion of food sources.

As an occasional occurrence, this might not be cause for alarm. A few dozen walrus have often come ashore in Alaska. Along the Russian coast of the Chukchi Sea, thousands of walrus congregate on beaches in late summer before heading south to the Bering Sea. But the conditions in today’s Arctic are prompting a major ecological shift and walrus face new pressures as they try to adapt.

Meanwhile, rapidly melting sea ice is opening the region to increased industrial activities, including oil and gas development and more ship traffic, which in turn have the potential to further stress marine mammals. The United States has halted commercial fishing in its Arctic waters for the foreseeable future as a precautionary measure. But commercial shipping plus offshore oil and gas activities are likely to spur extensive coastal infrastructure development and introduce oil rigs to waters where walrus feed. These human impacts must be minimized if walrus are to survive and flourish.

In the eastern Canadian Arctic, the narwhal’s future is just as uncertain. Long a source of fascination, Europeans once thought that the creature’s long spiral tooth protruding from the front of its head was like the horn of the unicorn. Instead, scientists discovered that the tooth is an extraordinary sensor for temperature, salinity and other ocean conditions and may help with navigation and feeding. Today, up to 60,000 narwhal, or 85 per cent of the world’s population, migrate in summer through Lancaster Sound, at the eastern entrance to the Northwest Passage. They spend winters feeding on Greenland halibut more than a kilometre below the surface of Baffin Bay.

As sea ice retreats and takes longer to re-freeze each fall, narwhal will also have to respond. Scientists have rated it as the marine mammal most vulnerable to the loss of sea ice. As with walrus, however, habitat changes are not the only risks for narwhal. Increased commercial fishing in Baffin Bay could reduce the species’ food sources as well.

The development of a sound, fishery-related ecosystem management plan will allow these marine mammals every chance to adapt as best they can. The Canadian government’s promise to create a national marine conservation area in Lancaster Sound also is a crucial step toward helping protect narwhal.

Losing sea ice not only impacts high-profile animals such as walrus and narwhal. Many species have adapted to live only in the Arctic, supporting a food web that begins with tiny algae growing under and in the ice. Conservation measures that encompass wildlife, fishing, shipping and drilling are needed now in Arctic waters, lest its ecology becomes a historical artifact rather than a vital part of our global heritage. And ultimately, if the loss of sea ice is to be slowed or reversed, the human causes of climate change must be addressed. An Arctic without ice deprives not just the narwhal and walrus, but all of us.
