An Australian engineer is hoping to use drones to plant 1 billion trees every year to fight an unfolding global catastrophe.
Deforestation and forest degradation make up 17 per cent of the world's carbon emissions — more than the entire world's transportation sector, according to the United Nations.
Burned or cleared forests release their stored carbon dioxide into the atmosphere, and land restoration experts say technology must play a big part in addressing the problem.
Dr Susan Graham has helped build a drone system that can scan the land, identify ideal places to grow trees, and then fire germinated seeds into the soil.
Drones can plant in areas previously impossible to reach, like steep hills.
The planet loses 15 billion trees every year and much of it is cleared for farmland to feed the world's booming population, but it's feared this could be exacerbating climate change.
"Although we plant about 9 billion trees every year, that leaves a net loss of 6 billion trees," Dr Graham said. "The rate of replanting is just too slow."
Now based in Oxford in the United Kingdom, she is working with an international team including an ex-NASA engineer who worked on the search for life on Mars.
Their company, BioCarbon Engineering, is backed by one of the world's largest drone makers.

Industrial-scale reforestation
Bulldozers and tractors can clear land rapidly — and replanting efforts haven't caught up.
Dr Graham is hoping to change that with a system that plants at "10 times the rate of hand planting and at 20 per cent of the cost", she said.
BioCarbon Engineering's CEO Lauren Fletcher said the drone could currently carry 150 seed pods at a time.
"We're firing at one a second, which means a pair of operators will be able to plant nearly 100,000 trees per day — 60 teams like this will get us to a billion trees a year," he said.
Mr Fletcher worked at NASA for two decades on projects including the International Space Station and with robotic technologies used in the exploration of Mars.
"I worked specifically on the intersection between biology and engineering on the life-sciences programs on the Space Station, so this has given me a lot of knowledge of how you take smart, cutting-edge engineering systems and apply it to a biological system," he said.
The firing drone follows a pre-set planting pattern determined from an algorithm, which uses information from a separate scanning drone.

To work out the best possible place to plant, the team uses the drone to map the area, looking to create a 3D model of the land.
"The data gets downloaded and we've developed the algorithms that use that data to make smart decisions about exactly where to plant and how to manage that ecosystem," Dr Graham said.

Opportunities to rehabilitate abandoned mines
The team has tested its drone technology around the world and was recently in Dungog, in the New South Wales Hunter region.
This involved trialling their seed-spreading drone to rehabilitate land once used by coal mines.
This drone — while not as efficient as the firing drone — spreads seeds over a far wider area.
"Coal mines have an enormous amount of land that they need to restore, both on the active mine site, once they've recreated a land form, as well as their offset areas ... around the mines," Dr Graham said.

"We've had quite a lot of interest in Australia and they see such a benefit in terms of saving cost, saving time, and being able to a better job of restoring their ecosystems, and getting data to actually show what they've done."
In Dungog, it was tested to see how it performed on a steep hillside.
"Tractors find it very difficult over steep and undulating land," Dr Graham said. "It becomes very dangerous to get a tractor onto a steep hillside.
"However, a drone doesn't matter, it's already in the air, it's already flying the shape of the land."

Finding solutions for depleting farmland
Global research organisation World Resources Institute (WRI) has warned that the amount of arable land is declining.
WRI's Sofia Faruqi said this needed to be turned around in order to produce enough food for everyone on the planet.
"The way we plant trees today is very similar to how we planted them hundreds of years ago," she said.
"So there's major room for innovation in increasing the success rate of tree planting and also in improving the maintenance and monitoring of the restored land."

Ms Faruqi said around the world there was an area the size of Latin America waiting to be restored — unlocking potentially "massive" benefits.
"People often see planting trees as a feel-good activity but in fact restoration of degraded land has very tangible benefits for all humans," she said.
"Restoring land can provide food for 200 million people. This is because planting trees adds vital nutrients and organic matter into the soil.
"Many of the world's biggest cities rely on forests for their water supply; for example in the US, more than half of drinking water originates in forests, which act like giant sponges.
"Finally ... trees are essential to fight climate change [because] half of a tree's weight is carbon and essentially the trees will dig carbon out of the atmosphere where it's dangerous, and they'll bring it into the soil where it promotes life and vitality."
She added it was important to experiment with technologies such as seed-planting drones to work out the best way to restore land in a cost-effective way.

World's Biggest Coal Company Closes 37 Mines As Solar Power's Influence Grows

The IndependentHarriet Agerholm

Plummeting price of renewable energy puts pressure on fossil fuel firms
India has announced it will not build any more coal plants after 2022 Getty
The largest coal mining company in the world has announced it will close 37 mines because they are no longer economically viable.
Coal India, which produces around 82 per cent of India's coal, said the mines would be decommissioned by March 2018.
The closures, of around 9 per cent of the state-run firm's sites, will reportedly save around 8,000,000,000 rupees (£98m).
India's solar sector has received heavy international investment, and the plummeting price of solar electricity has increased pressure on fossil fuel companies in the country.
The government has announced it will not build any more coal plants after 2022 and predicts renewables will generate 57 per cent of its power by 2027 – a pledge far outstripping its commitment in the Paris climate change agreement.
Plans for nearly 14 gigawatts of coal-fired power stations – about the same as the total amount in the UK – were scrapped in May, signalling a seismic shift in the India's energy market.
Analyst Tim Buckley said the move away from the dirtiest fossil fuel and towards solar in the country would have “profound” implications on global energy markets.
“Measures taken by the Indian government to improve energy efficiency coupled with ambitious renewable energy targets and the plummeting cost of solar has had an impact on existing as well as proposed coal fired power plants, rendering an increasing number as financially unviable," he said.
“India’s solar tariffs have literally been free falling in recent months.”
A report in February by Delhi-based research group, The Energy and Resources Institute (TERI), found that if the cost of renewable energy continued to fall at the same rate, India could phase out coal completely by 2050.

Final Chapter In Adani Loan Deal

Saturday Paper - Karen Middleton

While the dealings of the government's Northern Australia Infrastructure Facility remain shrouded in secrecy, pressure mounts over funding for the Adani rail line.

While federal politicians shouted and shivered through the last subzero sitting week of this parliamentary session in Canberra, arguing among other things about how best to keep on the nation's lights and heaters, another cohort with a keen interest in energy policy was gathering in warmer climes to the north.
Among those addressing the annual Developing Northern Australia conference, held this year in Cairns, was Sharon Warburton, the chairwoman of the somewhat opaque Northern Australia Infrastructure Facility, known as the NAIF.
The NAIF is a $5 billion-government-owned lender, set up to make concessionary loans to companies planning infrastructure projects in northern Australia that are of demonstrated public benefit and would not otherwise be able to proceed.
For its purposes, the area defined as northern Australia reaches below the Tropic of Capricorn, from south of Carnarvon in the west, across the whole Northern Territory, to just south of Gladstone in Queensland.
In its first year of operation, the NAIF has developed a reputation for secrecy, relying heavily on commercial-in-confidence to refuse to reveal beyond the most basic detail who has applied, for how much and how assessments are progressing.
The NAIF has not yet lent any money. But Warburton is hinting that it's close to a decision on at least one application, the one that's attracted the most controversy and has become an open secret: the request from Indian mining conglomerate Adani for $1 billion to fund a railway line to support its proposed Carmichael coalmine in Queensland's Galilee Basin.
"We know there is a lot of interest in NAIF and the Adani rail project," Warburton told the conference on Monday. "I can confirm we are in our due diligence phase on that project."
That translates as the final stage of assessment, with three other applications apparently also reaching finality. But, Warburton said, she could not say any more about Adani than that.
BRENDAN PEARSON WELCOMED WHAT HE SAYS IS A MOVE TOWARDS "A MORE RATIONAL DEBATE ON THE ROLE THAT COAL CAN PLAY".
"Put yourself in that position," she explained. "Would you expect people you were negotiating with to discuss publicly any of those details?"
Opponents of what would be oneof the world's biggest thermal coalmines are answering her rhetorical question with a "yes".
The proposed Adani Carmichael mine development has struck repeated setbacks, not least that it has struggled to secure financial backing. All of Australia's biggest banks have declined to invest, most recently Westpac, whose decision prompted Adani to accuse it of "choosing to bow to environmental activists".
More than a dozen other banks abroad have also shunned the project, on the grounds that low coal prices and an increasing focus on sustainable energy sources make coal an unattractive investment.
But Adani's Australian spokesman, Ron Watson, says the company is currently in "negotiations and discussions" with a potential overseas financier.
"The length of those discussions will take as long as they're going to take," Watson said.
He said the company was prepared for the NAIF to also take as long as it needed.
"If we have to wait, we have to wait. Patience, grasshopper, so to speak."
Resources and Northern Australia Minister Matt Canavan lashed out again this week at what he suggested was ideological prejudice against coal.
"There is a whole, in my view, ignorant and ill-informed campaign against fossil fuels and mining more generally across our country, and that puts at great risk our wealth because so much of our wealth comes from our natural resources," Canavan told Sky News on Thursday.
This week, the government reaffirmed its desire to build a "high energy, low emissions", or HELE, coal-fired power station to address future baseload power issues, accepting all but one of the recommendations in the recent energy report by Chief Scientist Alan Finkel.
The recommendation not accepted in its current form was the central one, the adoption of a clean energy target that would reward non-polluting forms of energy, but which Finkel recommended setting at an emissions threshold that would rule out even HELE coal-fired plants.
The Minerals Council of Australia chief executive Brendan Pearson welcomed what he says is a move towards "a more rational debate on the role that coal can play".
"Let the best energy source win," Pearson said.
Greens senator Larissa Waters said clean coal was "a lie".
"This is straight from the big tobacco playbook," Waters said. "Remember 'light' cigarettes? To meet the commitment under the Paris Agreement to keep global warming to safe levels, we need to reach zero pollution in the electricity sector transitioning away from coal. Building more coal-fired power stations is simply incompatible with the science."
Environmental activists continue to mount a strenuous campaign against any kind of coal-fired power and the Adani mine development in particular, on the grounds that it represents an investment in a backwards-looking energy source that will add to Australia's greenhouse gas emissions and damage the Great Barrier Reef.
The mine's backers argue it will provide a much-needed economic boost to central Queensland and – most importantly – jobs, although the company's original estimate of 10,000 has now been scaled back to about 1400.
Adani also has investments in massive solar farms in India and has proposed investing in solar energy in Australia, in both Queensland's Bowen Basin and in South Australia.
The company has sent mixed messages on whether it needs the NAIF loan to proceed, initially saying it wasn't essential and then saying it was, a distinction crucial to NAIF's considerations.
Details of any NAIF decision will only be published after it has been finalised and within 30 days of being taken.
Larissa Waters and Labor senator Murray Watt succeeded last week in establishing a senate inquiry into the NAIF, and Waters is pushing to have Adani called before it.
In recent senate budget estimates committee hearings, Labor and the Greens attempted to extract information on the status of the NAIF's deliberations in general and the fate of Adani's bid in particular.
As part of its processes, the NAIF must consult with Infrastructure Australia on projects it proposes to fund.
Greens leader Richard Di Natale asked Infrastructure Australia chief executive Philip Davies whether it had received a submission on the Adani rail line, as per the requirement that it must assess all projects seeking more than $100 million.
Davies said it had not.
Di Natale asked if the rail line was on IA's list of infrastructure priorities.
"That is not something that we have currently identified, no," Davies said, confirming that it had not conducted any cost–benefit analysis of the project.
Davies said neither the NAIF nor the Export Finance and Insurance Corporation, which acts on its behalf, had consulted with IA about the Adani project, nor any project in detail.
Adani faces local competition for a NAIF loan to build a rail line. Australian rail freight giant Aurizon has also applied.
Watt has been demanding information on how the NAIF will make its assessments.
"Regional Australia desperately needs new projects and new jobs, so we support the NAIF," Watt told The Saturday Paper. "But people need to have confidence that $5 billion in taxpayers' money will be spent independently and impartially."
In his sights in particular is NAIF director Karla Way-McPhail, who is chief executive of two companies that service the mining industry.
Minister Matt Canavan confirmed to a senate estimates hearing this month that Way-McPhail, who has spoken out in support of opening up the Galilee, was a friend whom he had recommended for the board.
"She is a successful businesswoman in my area of the world," Canavan said, noting both lived in Yeppoon. "… She is a very well-regarded individual in the community and brings a lot of business expertise, particularly from Northern Australia, to the board."
NAIF chief executive Laurie Walker declined to tell the senate estimates committee whether Way-McPhail or any other NAIF director had recused themselves from any discussions on the grounds of a potential conflict of interest. Walker said that was "not information that I think is appropriate to disclose".
She said more than six conflicts had been declared.
"All I can say is that I am comfortable that the board members understand their obligations and have complied with them," she told the senators.
Deputy Prime Minister Barnaby Joyce said recently that he would investigate any alleged conflicts of interest. But Canavan said he was unaware of any such investigation.
Karla Way-McPhail was one of two of the seven NAIF directors who did not attend this week's Cairns conference.
The Greens' main focus has been on the suitability of the loan applicant rather than the assessors.
Larissa Waters wants the government to insert a "suitable person" test into the NAIF's process for assessing loan bids, arguing she believes it would rule out Adani.
The Greens also want the environmental history test strengthened within environmental law and are calling for Adani's approvals for the Carmichael project to be reviewed on the basis of "revelations about their environmental and corporate history" in activities overseas.
Waters has produced a private member's bill to reflect the concerns but the government is not obliged to bring it forward for a vote.
The Queensland Resources Council insists that, notwithstanding the NAIF decision, the development can and should now go ahead.
"There is a high degree of confidence that the Adani mine will now proceed with the resolution of the native title issues," the council's chief executive and former federal minister Ian Macfarlane told The Saturday Paper.
But despite Adani having announced with flourish recently that it had taken the final decision to proceed, others argue there are still obstacles to be cleared.
Tim Buckley, a director at the Institute for Energy Economics and Financial Analysis, believes it is not viable without massive taxpayer subsidies.
"The green light that Adani made such a fuss about a couple of weeks ago was actually just a sham," Buckley told The Saturday Paper.
He has written a paper suggesting "defer, delay and pray" appear to be the company's unspoken watchwords.
Adani's Ron Watson said the project was absolutely viable.
"If it's not viable, what is [Buckley] worried about?" Watson asked. "We will go away. We will slip away into the darkness."
But he said far from doing that, Adani had already invested $3.3 billion in Australia alongside $40 billion in integrated baseload and solar investments across Asia. Adani was aiming to become Australia's biggest solar producer within a decade and to invest in agribusiness too.
While the Queensland government has promised a royalties concession if the development goes ahead, it has also decided not to process the NAIF loan if approved – something that may require federal legislation to circumvent.
And for the Carmichael mine to proceed, the company must have concluded an Indigenous land use agreement, or ILUA, with the area's native title holders.
Last week, the federal government and Labor combined to pass legislation to reverse a Federal Court ruling that all members of a registered native title claimant group in any relevant area were required to sign an ILUA for it to have force.
The move affected agreements well beyond the Adani ILUA and was welcomed by some Indigenous groups and opposed by others.
That followed Prime Minister Malcolm Turnbull's promise to Adani owner Gautam Adani during a meeting in India earlier this year that he would fix the native title problems that were preventing the development from proceeding,
But the Wangan and Jagalingou traditional owners are challenging the ILUA on three other grounds. The court hearing has been set down for next year.
OPPONENTS OF THE MINE ARE GEARING UP TO ARGUE THAT SUCH GLOBAL BAD PUBLICITY SHOULD BE GROUNDS FOR REFUSAL.
Originally, Adani had said it expected to achieve financial close on its Carmichael project by December this year. But recently that date was revised to March – the same month the court is due to hear the ILUA challenge.
What is not clear is whether there is a NAIF deadline by which an applicant must prove it has fulfilled all requirements, or whether an application can remain live for as long as that takes.
This week, Adani announced a new jobs portal for anyone interested in working on the project once it proceeds and is hiring senior executives, with plans to begin surveying and pre-construction in September.
"Adani has said that they are seeking to make financial close by later this year or early next year, and that would be the timing of any NAIF loan," Matt Canavan said.
In the latest public criticism of the whole proposal, an international group of high-profile conservationists wrote to Malcolm Turnbull late this week urging the government not to proceed.
The Ocean Elders, which include ocean explorer Jean-Michel Cousteau, marine biologist Dr Sylvia Earle, businessman Richard Branson and Jordan's Queen Noor, wrote that the mine would worsen damage to the Great Barrier Reef that Australia, as its custodian, had a global obligation to protect.
The group's spokeswoman, marine biologist Earle, told ABC Radio that Australia should reject fossil fuels and hence the Carmichael mine, despite its advanced state of official approval.
"It's never too late as long as the people and as long as rational individuals with power can change course, now that we know what we know," Earle said.
A prime ministerial spokesman declined to comment on the letter.
One of the conditions of the NAIF approving a loan is that it must not be likely to "cause damage to the Commonwealth Government's reputation or that of a relevant State or Territory government".
Opponents of the mine are gearing up to argue that such global bad publicity should be grounds for refusal.
In her speech to the Cairns conference, Sharon Warburton said the NAIF must both reflect government policy and be independent of it.
"First NAIF must align with Commonwealth policy, and that is a whole-of-government position, remembering it is taxpayer funds we are deploying," Warburton said. "Secondly – importantly – we cannot lend funds if all regulation at both a Commonwealth and state level are not in place.
"The other tremendously important parameter under which we operate is that it was set up to be an independent body making decisions independently of all outside influence."
Given the attempts at influence being made on all sides of the argument, that may prove to be a challenge.
