David Cameron has defended his decision to spend 0.7% of national income on overseas aid as prime minister, calling it "an investment in our own security".

The former Tory prime minister said the debate should not be on whether money is spent on aid - but how it is spent.
Mr Cameron made the comments in an article for the Guardian, in which he revealed he is to chair a high-profile commission on overseas development.
The group will research fragile and conflict situations globally.
Spending on foreign aid rose to about Â£12bn when Mr Cameron was prime minister, and, writing in the Guardian, he said: "My view is clear: aid works."
International Development Secretary Priti Patel has warned that major multinational aid funding may be cut unless it provides better value for money, although the government remains committed to the 0.7% target.
To address concerns about value for money in aid spending at a time of austerity, ministers want to spend more of the money not only relieving poverty but also promoting Britain's strategic interests.
'Mass migration'
BBC diplomatic correspondent James Landale said this Â£700m "empowerment fund" could be used by the Foreign Office and other departments to help developing countries counter the threat of Islamic extremism or the clout of Russia.
In his article, Mr Cameron said that between 2011 and 2015, Britain had helped vaccinate 67 million children, saving at least 1.2 million lives from diseases such as pneumonia and diarrhoea.
"Such financial help doesn't benefit just the countries that receive that aid: money spent on international development is an investment in our own security," he said.
"Because if we don't tackle poverty abroad, the results are visited upon us at home.
"Mass migration, epidemics such as Ebola, climate change and pollution - none of these things respect national borders."
Mr Cameron, who stepped down as prime minister after the UK voted to leave the EU last summer, said he had decided to become unpaid chairman of the new Commission on State Fragility, Growth and Development, with Oxford University and the London School of Economics, to research what made a state fragile.
"As prime minister, I made sure that half Britain's aid spending went to the most fragile states," he said.
"Today, state failure is increasing and nearly half the world's poor people will soon live in fragile states and regions."
'Soft power'
His commission, which will be co-chaired by Donald Kaberuka, the special envoy of the African Union Peace Fund, and Adnan Khan, the International Growth Centre's research and policy director, will be joined by eight commissioners from around the world to address what makes states fragile and keeps them that way.
The group will take evidence from witnesses ranging from military commanders in Afghanistan to aid workers in Syria, in the hope of "generating the most cutting-edge recommendations that governments, donors and NGOs (non government organisations) can put into practice".
This includes looking at the role small, medium and big companies can play - and how governments can create a tax base so they can pay for their own development.
"From defeating fascism and communism to spending 0.7% of our national income on aid - the only major economy to do so - Britain has always led the way when it comes to making this a safer, fairer, more prosperous world," Mr Cameron said.


Britain's Andy Murray fought back to beat Frenchman Richard Gasquet and set up a semi-final against Roger Federer at the Cincinnati Masters.

The third seed, who saved a match point against Grigor Dimitrov on Thursday, won 4-6 6-1 6-4 on Friday.
Murray said: "I fought and gave everything I had, but thankfully it's just been enough in the last two days."
Federer beat Feliciano Lopez 6-3 6-4, while Novak Djokovic and Alexandr Dolgopolov reached the other semi.
The Scot has now won more matches in 2015 then any other male player, 56, and with the US Open beginning on 31 August, he will be looking for a third Grand Slam title.
Against the dangerous Gasquet, he failed to convert a break point in the eighth game of the opening set and then paid the penalty when his opponent broke his serve in the next game to serve out for the set.
Murray recovered to earn a double break in the second and although he had break points against him in two of his own serve games, he took the set 6-1 in 31 minutes.
He broke Gasquet again to lead 2-1 at the start of the third, but just when he appeared to have broken his opponent's resistance, he was distracted by the lengthening shadows and the spider camera situated above centre court and momentarily lost his composure and then his serve.
The world number two continued to look threatening on the Frenchman's serve and earned three break points in the ninth game. Although Gasquet saved one of them, he double-faulted to give Murray the opportunity he needed to serve for the match.
Murray added: "I was sluggish at the start, but as the match went on I was striking the ball better and was dictating a lot of points without having to do as much running.
"Physically I'm tired and my body hurts, but with the US Open coming up these matches are good for me physically and mentally to get through."
Federer, 34, needed just 61 minutes to see off Lopez, with the Swiss chasing a seventh Cincinnati title.
The world number one looked imperious in his 6-4 6-1 victory over his French Open final conqueror Stan Wawrinka, and will now face qualifier Dolgopolov, who upset world number six Tomas Berdych6-4 6-2.
Djokovic has won every Masters 1000 title except Cincinnati and will become the first player to complete the set of nine if he wins.
"My performance came at the right time against one of my biggest rivals and the guy I lost to last time we played in the finals of the French Open," said the Serb.
"Obviously I approached this match very seriously in trying to prepare myself and get myself in a good position to win."
In the women's quarter-finals, world number one Serena Williams overcame stern opposition from Serb Ana Ivanovic to win 3-6 6-4 6-2.
"I was lethargic in the first set and she played incredibly well; I just had to do better," said the American, playing her final tournament before she tries try to win the calendar Grand Slam at the US Open next month. .
"This was my best performance since (winning) Wimbledon. I hope to take the momentum into the next match."
Williams will next play 14th seed Elina Svitolina, after the Ukrainian beat Czech Lucie Safarova 6-4 2-6 6-0.
Third seed Simona Halep of Romania saw off Russian Anastasia Pavlyuchenkova 7-6 (7-3) 6-2, and Serbia's Jelena Jankovic beat Slovakian qualifier Anna Karolina Schmiedlova 6-4 6-2.


Formula 1 will go ahead with its controversial plan to award double points at the last race of the season.

The proposal - the idea of F1 supremo Bernie Ecclestone - was raised at a meeting of the sport's bosses but no attempt was made to overturn it.
Ecclestone thinks the idea will help keep the championship alive for as long as possible after Sebastian Vettel's recent dominance of the sport.
The Red Bull star has won the drivers' title for the last four years.
Prior to Wednesday's meeting in Geneva, one leading team boss, who wanted to remain anonymous, told BBC Sport that "most participants would agree to ditch" the points proposal if they were given the chance.
If the new system had been in place for the last two decades, three world titles would have been won by another driver.
In 2012, Fernando Alonso would have beaten Sebastian Vettel. In 2008, Felipe Massa (pictured above left) would have denied Lewis Hamilton. And in 2003, Kimi Raikkonen would have edged out Michael Schumacher.

He claimed Ecclestone and the FIA, which governs the sport, had "completely misjudged the predictable negative response from the public".
Ferrari president Luca Di Montezemolo also said last month that he was "not enthusiastic" about the plan, arguing it was "too artificial".
However, none of the teams chose to make a major issue of the plan at the meeting, probably because they felt it was not worth falling out with Ecclestone over.
Team bosses also discussed the introduction of a cost-cap in 2015.
Certain agreements were made, which will now go to a vote of the FIA World Council, the sport's legislative arm, on Thursday, but the teams did not agree on a figure for the upper limit of spending.
That topic will now be discussed at a future meeting.
F1 believes it needs a cost cap for three main reasons:
1) The barrier to entry is too high - it is unlikely any new team would want to enter knowing it would be four to five seconds off the pace with no chance of progress
2) The high costs mean there are no independent engine manufacturers in the sport, which means F1 is beholden to motor manufacturers, which tend to come and go from the sport at will
3) There is too little competition across the grid and an ever-reducing chance of a surprise result, such as a smaller team qualifying on the front row or getting a podium finish.
Introducing a cost cap of, say, £150m, would not reduce the costs of the smaller teams as many are spending less than that.
But it would carve in the region of £100m off the budgets of the top teams, like Red Bull, Ferrari, Mercedes and McLaren.


Woodland in Conwy is "under threat" if a hydro-electric scheme goes ahead, a charity has said.

It is understood proposals for a £12m project at Fairy Glen would mean half an acre of wood is destroyed, Coed Cadw has claimed.
It has asked Snowdonia National Park Authority to reject RWE Innogy's plans.
The scheme would be capable of generating up to 13,000 megawatt hours of electricity each year, enough to supply around 2,700 households.
RWE Innogy revealed the plans three years ago and the authority has been carrying out a consultation.
It would involve getting water from the river above Penmachno bridge and diverting it through more than half a mile (1km) of pipeline around Fairy Glen, before returning it to the river near the River Lledr junction.
Rory Francis from Coed Cadw said: "When woodlands such as this, which are centuries old, are lost they cannot be replaced.
"We urge the Snowdonia National Park planning committee to say no to the  proposal and for the company involved to think again."
RWE Innogy said a consultation had taken place, and that the project had been designed to to minimise any environmental impact.
A spokesman said: "Let's not forget that one of the biggest threats to the environment and wildlife is climate change itself, and so it is important that we are able to deliver projects like this which make an important contribution towards tackling climate change."


A top police officer who exposed a breast and mocked a colleague's "boob job" has been allowed to keep her job.

Assistant Chief Constable Rebekah Sutcliffe, 47, told temporary Supt Sarah Jackson she would "always just be known as the girl who had the tit job".
In December, a disciplinary panel ruled the Greater Manchester Police (GMP) officer had breached standards of professional behaviour.
But Deputy Chief Constable Ian Pilling ruled she could keep her job.
Ms Sutcliffe told Ms Jackson - who has since transferred to Cumbria Police - her "credibility was zero", she was as a "laughing stock" and that she was "silly, vain and frivolous" for going under the knife.
She is alleged to have said: "It does not matter how hard you work now, because you will always just be known as the girl who had the tit job."
She then pulled down the front of her dress to expose her left breast and said: "Look at these, look at these, these are the breasts of someone who has had three children.
"They are ugly, but I don't feel the need to pump myself full of silicone to get self-esteem."
The panel heard Ms Sutcliffe made repeated attempts to apologise to Ms Jackson the following day and told her she "deeply regretted" it.
She later said she was "frazzled" and had been drinking too much to cope with stress in her personal and professional life.
The panel stated her gross misconduct had taken her to the "very" brink of dismissal, but accepted it was out of character and recommended a final written warning.
The officers were attending a Senior Women In Policing conference at Manchester's Hilton Hotel when Ms Sutcliffe verbally attacked her colleague.
Ms Sutcliffe, who was the most senior female GMP officer at the time, had admitted misconduct but denied gross misconduct.
Her counsel, John Beggs QC, had handed the panel more than 200 pages of testimonials, with many officers speaking of Ms Sutcliffe as "inspirational", "visionary" and "a strong leader".
Announcing his decision to follow the panel's recommendation, Mr Pilling said: "Despite being absolutely appalled at her behaviour and all too aware of the damage to public confidence, I do not think I can take a different view without any significant reason to do so."
Following the decision, Ms Sutcliffe expressed "deep regret" about what happened and said the "responsibility for what happened is mine and mine alone".
"I did not mean any of the things that I said and I am dismayed that I was so unkind and unfair," she added.
"I am very grateful that I have been given the opportunity to return to work.
"On my return, I will bring the very best of my abilities to serve policing and the public as well as I am able."
Ian Hopkins, chief constable of GMP, said it had been "an incredibly difficult time" for the police service, where "the events in May... cast a shadow over what was an important event to recognise the contribution of women in policing".
"The details in the report have clearly outlined the panel's position and legally left little alternative but to follow the panel's recommendation."
He added: "ACC Sutcliffe has been given a chance to demonstrate that she is committed to serving the people of Greater Manchester.
"We will now work with her to consider how she best achieves this in support of Greater Manchester Police. "


A "significant fire" which broke out at a recycling centre has continued to blaze throughout the night.

Cornwall Fire and Rescue said the fire at St Erth, near Hayle in Cornwall, started at about 20:15 BST and more than 70 firefighters are still fighting it.
Devon and Cornwall Police are also in attendance. There are no reports of any injuries.
A large diesel and oil tank was caught up in the fire, firefighters said.
Latest news on the fire and other stories
Harry Hodgson, who was on a train which pulled into St Erth station, said the "huge black smog" could be seen from a mile away.
"It just erupted and basically took a huge building out within minutes and all of a sudden it was just an uncontrollable inferno, a massive blaze", he said.
Mr Hodgson said "the general mood was excitement" because no one had been injured and people were "enjoying the power and the beauty of the fire".
Great Western Railway said the St Erth station and the St Ives train branch would be closed all day. Disruption is expected on services between Truro and Penzance until the end of service.
People living in the area have been advised to close windows and remain indoors owing to the large plumes of thick, black smoke.


The government has unveiled new tools and advice for farmers as part of a fresh campaign to tackle bovine TB.

A new website has been launched for farmers to find practical advice on dealing with the disease on their land.
A five-point biosecurity action plan and poster campaign are also included in the initiative.
The measures are being promoted by organisations such as Defra, the Animal and Plant Health Agency and the National Farmers' Union.
Recommended actions include asking for a herd's TB history before buying cattle, and taking steps to minimise wildlife access to cattle, their feed and housing.
Speaking at the launch of the campaign at Hartpury College in Gloucestershire, Farming Minister George Eustice said "good progress" is being made to  eradicate TB in England.
However, he said reducing the risk of disease entering a farm is a "crucial element" to end the "devastation" it causes for farmers and rural communities.
"There are simple and practical ways for farmers to reduce risk to their herds and neighbouring businesses from bovine TB which are set out in this new action plan approved by vets and farming experts," he added.
Mr Eustice encouraged all cattle farmers to visit the new website and "think about the actions they could take to make a difference to improving the security of their herd".
Bovine tuberculosis (TB) is an infectious disease of cattle and is caused by the bacterium Mycobacterium bovis (M. bovis), which can also infect and cause TB in badgers, deer and other mammals.
Badgers, which some claim transmit TB to cattle, have been subjected to culls in Somerset and Gloucestershire for three years running. A pilot cull in Dorset is also being held this year.
According to Defra, about 30,000 cattle were slaughtered in Great Britain in 2014 because of bovine TB.


Scotland have appointed American Erik Olson as their new national basketball coach on a two-year contract.

He has been charged with qualification for the Commonwealth Games in 2018 and will work closely with Scotland's only professional team, Glasgow Rocks.
Olson has also been given the task of finding players capable of playing for Scotland and Team GB in the future.
He has previously coached sides in Australia, Iceland and United States and played for Falkirk Fury.
Olson said: "To me, this is not an overnight success story but a story in which we will continue to see high-level players come out of the national team and now Rocks programme for years to come.
"We now have an elite model within Scotland and, with the Rocks partnership, we will be able to directly implement a proper training method to allow not only our young players but also key national team players the environment they need to develop and eventually turn into elite players themselves."
A former shooting guard, Olson helped take Fury to their Scottish Cup title in 2009 before moving to play for Wagga Heat of the Australian Waratah League.
He was awarded Eurobasket Icelandic Coach of the Year in 2015 as his side, FSu Academy Iceland, were crowned play-off champions and won promotion to the Premier League.
Olson has also been involved in the USA Under-18 select squad and the Icelandic national team.


Lord Coe is the right man to lead the crisis-hit IAAF, according to the author of a report claiming "corruption was embedded" within the organisation.

Media playback is not supported on this device
Coe, 59, became boss of the body that governs world athletics last August after eight years as a vice-president.
Since then, the IAAF has come in for heavy criticism, accused of helping cover up systematic doping in Russia.
But Dick Pound, whose report damns IAAF governance, insists he "can't think of anyone better" than Coe to lead it.
"I think it's a fabulous responsibility for the IAAF to seize this opportunity and, under strong leadership, to move forward," said Pound, chairman of the independent World Anti-Doping Agency (Wada) panel which wrote the report.
"There's an enormous amount of reputational recovery that needs to occur here and I can't think of anyone better than Lord Coe to lead that."

Pound's 89-page report concluded that corruption within the IAAF "cannot be blamed on a small number of miscreants".
It was also particularly scathing of former IAAF president Lamine Diack, who stood down and was replaced by Coe after 16 years in charge.
It concluded the Senegalese was "responsible for organising and enabling the conspiracy and corruption that took place in the IAAF".
The report also claimed the IAAF Council, which included Coe, "could not have been unaware of the extent of doping in athletics".
Coe, a former British MP, was present at Pound's news conference, having insisted on Wednesday there had been no cover-up.
He also said he had no intention of standing down.
Following the report's publication, Coe admitted: "I know how serious this is. We are a failed organisation.
"I'm sorry if my language has in any way demonstrated a sort of a lack of understanding about the depth of this."
He told BBC Sport that the IAAF - the International Association of Athletics Federations - would "redouble our efforts, to be clear to people we are not in denial".
And Coe re-emphasised: "My responsibility is to absorb the lessons of the past and to shape the future. The changes I am making will do that. The road back to trust is going to be a long one."
Diack is firmly in the line of fire. The report also concluded he:
This section of the report is particularly scathing:
"The corruption that occurred within the IAAF was not at the level of some foreign currency trader in a bank carrying out unauthorised transactions, without the knowledge or permission of the responsible bank officers.
"Here it started with the president of the organisation. It involved the treasurer of the organisation. It involved the personal counsel of the president, acting on instructions of the president. It involved two of the sons of the president. It involved the director of the medical and anti-doping department of the IAAF.
"The corruption was embedded in the organisation. It cannot be ignored or dismissed as attributable to the odd renegade acting on his own.
"The IAAF allowed the conduct to occur and must accept its responsibility. Continued denial will simply make it more difficult to make genuine progress."
BBC sports editor Dan Roan quizzed the former boss of Wada.

It was already reeling from a number of damaging revelations and was strongly criticised for its failure to tackle doping.
In fact, it was only after Pound accused Russia of systematic doping practises in the first part of his report last November that the IAAF stepped in and banned Russian athletes from competition.
Pound said: "The commission has been troubled by the apparent unwillingness of the IAAF to acknowledge that the conduct does indeed reflect on the IAAF and that it must assume its responsibilities for what went wrong."
Worse could follow for the IAAF, too. French police have issued a 'wanted' notice via Interpol for Papa Massata Diack, the son of the former IAAF president Lamine, on charges of corruption and money-laundering.
On the day of his election in August, Coe said suggestions his organisation was complicit in a doping scandal were "just inaccurate".
Thursday's allegations call into question that argument.
They also add to the pressure on a man who has been a key figure within the IAAF since 2007, when he was made a vice-president.
The report says Coe's right-hand man Nick Davies, who stepped aside from his position as the association's chief of staff last month, was "well aware of Russian 'skeletons' in the cupboard".
Coe, who led London's successful staging of the 2012 Olympics and Paralympics, became IAAF president last year.
In an IAAF statement hours after the report was published, it said it "fully acknowledges and accepts the extreme gravity of the commission's findings".
In the statement, Coe said he "cannot change the past", but would "not repeat its mistakes".
Coe has again come out out fighting, as he did following part one of the Wada report - and he still has his backers. There's Pound, for a start, as well as Brendan Foster - the British former long-distance runner - who said his close friend was still the right man to lead the IAAF.
"He's hurting with all this," said the former British middle-distance runner, prior to Thursday's announcement. "But Seb Coe is determined like no-one else can be determined. He's going to change this thing."
Michele Verroken, the former head of anti-doping at UK Sport, is also backing Coe to lead the IAAF out of trouble.
"If not Seb, who?" she asked. "Quite honestly, he is very capable of doing this. It's a matter of whether he gets the support to do it."
IAAF ambassador Kajsa Bergqvist, Sweden's world and European champion and an Olympic bronze medallist, said she met Diack 15 to 20 times and that he "was always a person probably more interested in the power his office gave him than he was in the sport itself".
Wada president Craig Reedie called the actions "criminal" and "hugely disturbing", while sports minister Tracey Crouch said the findings of the report were "extremely alarming".
Former Great Britain athletes Roger Black and Kriss Akabusi both said there were no major surprises in the report, and backed Coe, as did marathon world record holder Paula Radcliffe.
She said: "To single out Seb that he had an inclination of what was going on - I don't believe he did. I believe he had heard rumours, knew things needed to change, which is why put he put himself on the line and ran for presidency.
"If we attack and attack, then he might say 'it is not worth it'. It is then athletics' loss."
However, Akabusi described the IAAF president as "naive" for not being aware of the scale of Russian doping.
"He was a world-class athlete and he's going to need to be a world-class administrator and politician now," said Akabusi.
Meanwhile, Russia sports minister Vitaly Mutko called the report "absurd", claiming it was "almost accusing" the nation's president Vladimir Putin "of doping".
BBC Radio 5 live athletics correspondent Mike Costello:
"Lord Coe's reputation is on the line, especially with what he's been saying about Lamine Diack being the 'spiritual leader' of the sport.
"Time after time he said there was no cover-up, but of course there was a cover-up, Wada chairman Dick Pound said today.
"There has to be some guilt by association for Coe. Yet within athletics there is a feeling that if not Seb Coe then who else?"
BBC Radio 5 live sports news correspondent Richard Conway:
"Athletics is still in a grip of a huge crisis and the report shows deep-rooted corruption within the IAAF.
"Lord Coe says he is the right man to lead the organisation but given the report said the ruling council, which Coe was a member of, could not have been unaware of doping problems, that is going to be a significant issue for him.
"Yet that backing from Wada chairman Dick Pound is crucial because without it Coe would be facing a tougher task to keep his role as IAAF president.
"Now he has a bit of political capital to take forward."


Brazilian police say they are hunting a gang of mostly blonde young women who have committed a series of kidnaps and robberies in Sao Paulo.

The criminals have been targeting wealthy women in shopping centres, Sao Paulo's anti-kidnap police unit says.
The victims are followed to their cars, where they are robbed and held captive at gunpoint while the gang uses their credit cards to make luxury purchases.
Police said the "blonde gang" consisted of young, educated, middle-class women.
Sao Paulo civil police anti-kidnap division chief Joaquim Dias Alves told BBC Mundo: "One or two speak more than one language, and some have been educated overseas.
"They are really pretty girls, well-dressed and made up," he said.
The gang tend to target women who look similar to them, so they can assume the victim's identity while they use their credit cards.
They are thought to have been operating for three years, and to have robbed at least 50 people.
Police say they have begun to break up the gang, with three suspects arrested, including one man.
So-called "express kidnappings" - where victims are held for a few hours while their bank accounts and credit cards are drained - are a common crime in Latin America.


Tony Blair has declined an invitation to answer questions about why Colonel Muammar Gadaffi was never asked by the government to compensate victims of IRA attacks carried out with weapons supplied by Tripoli.

In December, the former prime minister wrote to the Northern Ireland Affairs Committee.
He said "any attempt to implicate me in deliberately trying to stop IRA victims receiving compensation is utterly without foundation  and wrong".
The chair of the committee, Conservative MP Laurence Robertson, then invited Mr Blair to appear in person to answer further questions about the issue.
However on Friday, Mr Blair's office said he "does not believe that appearing before the committee, simply to repeat what he has already said, would do anything to further the cause of the victims and their families."
In his December letter, Mr Blair said the issue of compensation for IRA victims was never raised with him, as far as he is aware.
The DUP's Gavin Robinson accused Mr Blair of snubbing victims.
"There are other mechanisms which the committee can use to compel witnesses to appear and I believe that strong consideration must be given as to how we proceed," he said.
The United States negotiated a significant financial package for victims of the Pan Am jet brought down over Lockerbie and those killed in a Berlin disco bombing, which was blamed on Libyan agents.
Mr Blair said he understood "why victims of IRA terrorism should have wanted their claims raised at the same time as the settlement of the Lockerbie compensation in 2008".
However, he said that "for the Americans, this was never going to be part of any settlement since they were focused on US citizens affected by Lockerbie and the Berlin discotheque bombing".
Mr Blair said he "never tried to get the Americans to exclude the claims of IRA victims" and he "did not raise the issue with President Bush".
He pointed out that when the compensation was under discussion in 2008 he was no longer in government.
The former Labour leader said "any attempt to implicate me in deliberately trying to stop IRA victims receiving compensation is utterly without foundation and wrong".


The head teacher of a school where a pupil died after a wall fell on her has told an inquiry there had been a proposal to remove the structure before the accident.

Stephen Kelly said the work did not go ahead because of a lack of funds.
Keane Wallis-Bennett, 12, died at Liberton High School in April 2014.
But Mr Kelly told a fatal accident inquiry there had been no concerns over the wall and the proposal to remove it was part of a refurbishment programme.
Earlier, a teacher told the inquiry no one had reported concerns about the structure to her.
Mhairi Henderson said she had never seen anything about the fabric of the building that caused her concern.
She said she could not recall any pupil saying the modesty wall was wobbly.
The hearing in Edinburgh has previously heard of the moments after the wall collapsed and crushed Keane to death.
In a statement read to the inquiry on Tuesday, PE teacher Kerry Sweeney said she heard a bang from a girls' changing room.
She said she heard pupils shouting and saw panic on their faces. She described how she found a wall on top of Keane.
She said the pupil was lifeless, not conscious or breathing.
Both Ms Sweeney and head of PE Stuart Robertson said no-one had previously reported any problems with the modesty wall.
In her opening remarks on Monday, Sheriff Principal Mhairi Stephen said the two-week inquiry would focus on why the wall collapsed, why it collapsed when it did and the property maintenance regime at the school.
The inquiry at Edinburgh Sheriff Court continues.


Two young boys were left home alone in Bradford with just a pan of soup to eat when their mother went on a two-day trip to Paris, a court has heard.

The brothers, aged six and 11, were found by police after the younger boy told his teacher his mum was in France.
The single mother had taken the trip to make arrangements for her wedding to a man she met online.
She was sentenced to six months in jail, suspended for a year after admitting two charges of child neglect.
Bradford Crown Court heard earlier the woman, who cannot be named for legal reasons, went to Manchester Airport in March and boarded a flight to Paris leaving the youngsters "home alone".
Prosecutor Philip Adams told the court she intended to fly back the next day, but would not have arrived home until about midnight.
The court was told the younger boy's school tried unsuccessfully to contact his mother before his older brother turned up to collect him.
He was allowed to go with his brother, but the school alerted police and the boys were placed in overnight accommodation.
Their mother was arrested the following day when she returned.
She told police she had travelled to Paris to make arrangements to marry and had initially wanted the boys to stay with a friend.
She said she was then "persuaded" by her older son that he and his brother would be fine at home.
Defending her, Tom Rushbrooke said she realised that she had made a "terrible mistake", and in all other respects was a caring mother.
Sentencing her, Judge Robert Bartfield told her she had put them "in significant danger".
However, he said the case was different from those where people went on holiday leaving small children behind, and fortunately no harm was done.
Judge Bartfield said as the boys had only recently been returned to their mother, this had persuaded him not to impose an immediate jail sentence.
The court also heard that she still hoped to go ahead with her wedding.


Two Welshmen have received knighthoods in the Queen's Birthday Honours.

Rugby legend Gareth Edwards, from Bridgend, was awarded the honour for services to sport and charitable services.
Classical composer Karl Jenkins, from Gower, was honoured for services to composing and crossing musical genres.
Actor and singer Michael Ball, who has a Welsh mother and says he considers himself "Wenglish", was appointed OBE for services to musical theatre.
Jenkins, the composer of The Armed Man: A Mass for Peace and Adiemus, is the first Welsh-born composer to be honoured with a knighthood.
He said he was "delighted by this great honour and the recognition of my music, and am grateful and humbled that my works have been able to reach out to so many performers and listeners around the globe".
Ball said it was "one of the biggest thrills I've had so far in my career and in my life".
He said: "I'm incredibly grateful and incredibly humbled, well, not over-humbled because I'm going to show off about it."
Steven Moffat, producer of Cardiff-filmed Doctor Who, was appointed OBE for services to drama.
BBC Wales Director, Rhodri Talfan Davies, said: "We're thrilled to see Steven's creative brilliance being recognised today.
"Not only has he enthralled countless millions of viewers across the world, he has helped rocket-boost the Welsh creative sector, inspiring a new generation of talent here in Wales to make their mark on the global stage."
Moffat said: "I'm not the least bit cynical, or the least bit trying to be cool about it. I'm just really, really happy."
Elsewhere in Wales, foster carers Steve and Wendy Taylor, from Swansea, who have looked after more than 1,000 youngsters over 31 years, were both appointed MBE.
Mrs Taylor said: "Fostering is a tremendously rewarding role and we hope other people will hear our story and come forward to care for teenagers in particular too."
Bookbinder Trevor Lloyd, from Knighton in Powys, who was appointed MBE, said he was "delighted" to have his work recognised and that he was "absolutely hooked" on bookbinding from the moment he was introduced to the craft 35 years ago.
Mountain Rescue leader John Hulse, from Conwy, was also among those named in the Honours for his work with Ogwen Valley Mountain Rescue.


The owner of a security firm hired by Donald Trump's Aberdeenshire golf business has been jailed for four years over a £400,000 VAT fraud.

Kevin McKay, of Aberdeen, charged his clients VAT but lied on his HMRC tax returns.
He claimed his company IPPS was making less than 10% of its actual sales.
The security guard then transferred large sums of money from his business bank to his personal account then sent money abroad.
More than £100,000 was switched to a Romanian bank in September 2010 after accumulating in his savings account over several weeks.
During his trial at Aberdeen Sheriff Court, McKay claimed to have looked after pop star Britney Spears and members of the Saudi royal family during his career as a bodyguard.
The court heard IPPS security guards provided mobile patrols at President Trump's golf course on the Menie Estate in Aberdeenshire.
A total of 136 visits were listed on an invoice between 2008 and 2009.
Other invoices from other firms showed that incorrect figures were submitted for some quarters to HMRC.
The court heard McKay's ex-wife Susan was initially charged with an offence relating to the reckless submission of VAT returns, but the case against her was later dropped.
Last month, a jury of nine men and six women found McKay guilty of being concerned in the fraudulent evasion of VAT worth £419,799 between August 2008 and May 2014.
He was also found guilty, following a six-day trial, of removing criminal property from Scotland by transferring £100,473.98 into a Romanian bank account.
The account belonged to the mother of a woman McKay was in a relationship with.
McKay was sentenced to three years in prison for the VAT fraud with an additional year in prison for removing criminal property abroad.
Cheryl Burr, assistant director of HMRC's fraud investigation service, HMRC: "Tax evasion robs the public purse of vital funds.
"The vast majority play by the rules and pay their dues, but some like McKay attempt to undermine the system by evading VAT to line their own pockets and gain an unfair advantage over legitimate businesses. Our actions put a stop to that."


A Japanese mountaineer who has previously lost nine fingers to frostbite is nearing the final stage of an attempt to climb Mount Everest.

Latest contact suggests that Nobukazu Kuriki, 33, has reached the South Col, where he will rest before a final push later on Saturday to reach the summit.
Mr Kuriki is the first person to attempt the climb since Nepal's devastating earthquake in April.
It will be his fifth try at reaching the summit in the past six years.
Mr Kuriki is expected to rest on the South Col for about seven to eight hours before attempting the final leg of the climb.
It is not uncommon for climbers to set out for the summit late at night to reach the top around dawn, Ang Tsering, the president of the Nepalese Mountaineering Association, told the BBC.
Tackling the final stretch overnight allows climbers to reach the summit and descend in daylight, and the lack of heating from the Sun can mean lower winds.
"We are very much hoping he will be successful and come back OK," Mr Tsering said.
Mr Kuriki, who arrived in Nepal more than a month ago to begin acclimatising, is so far the only person scheduled to climb Everest during the challenging autumn season.
He is following the same route used by Edmund Hillary and Tenzing Norgay when they became the first people to reach the summit in 1953.
Mr Kuriki prefers to climb in winter, alone and with minimal gear. "This is the purest form of climbing and it is worth the extra danger," he has said.
He has taken on Everest alone four times in the previous six years but has been forced to abandon the climb each time with the summit in view.
In 2012, he lost all of his fingers and one thumb after spending two days in a snow hole at 27,000 feet (8,230m) in temperatures lower than -20C.
His injuries present significant challenges in even the most basic climbing manoeuvres.
"I do feel nervous and afraid," he told Reuters shortly after arriving in Nepal.
"This is only natural before attempting the challenge of climbing Everest, particularly after the earthquake and at this time of year."
Nepal's lucrative climbing industry was destroyed by the 25 April earthquake which killed more than 9,000 people and the avalanches that followed.
If Mr Kuriki is successful, his climb may help to reinvigorate the ailing industry, correspondents say.


Malaysia is asking other Indian Ocean islands near French-owned Reunion to be on the lookout for more possible debris after a wing part suspected of being from missing flight MH370 came ashore.

The Malaysia Airlines plane, carrying 239 people, vanished in March 2014.
The Boeing-777 was travelling from Kuala Lumpur to Beijing.
The wing part discovered on Wednesday has been taken to mainland France for tests. But other items found at the weekend were not from an aircraft.
The BBC's Karen Allen, on Reunion, says one of the pieces was found on a rocky beach just north of where the suspected plane wing part was spotted.
A team of police and police photographers was called and the object was taken away.
However, Malaysia's Director General of Civil Aviation Azharuddin Abdul Rahman told Associated Press: "I read all over media [the new debris] was part of a door. But I checked with the Civil Aviation Authority, and people on the ground in Reunion, and it was just a domestic ladder."
The Agence France-Presse news agency said on Sunday that one of its photographers had also seen a mangled piece of metal inscribed with two Chinese characters, attached to a leather-covered handle and measuring 100 sq cm being placed into an iron case and carried away.
But some social media commentators suggested it might be a kettle.
A source close to the inquiry told AFP that "no object or debris likely to come from a plane" had been submitted as evidence on Sunday.
A spokesman in the town of St Andre, where the wing part was found, said that while people were more vigilant, "they are going to think any metallic object they find on the beach is from flight MH370".
"But there are objects all along the coast, the ocean continually throws them up," Jean-Yves Sambiman told AFP.
Malaysia's transport ministry says it now wants to expand the search for more debris around Reunion.
Malaysia will ask regions nearby to alert it if they find any debris that could be from MH370.
Transport Minister Liow Tiong Lai urged the regions to allow experts "to conduct more substantive analysis should there be more debris coming on to land".
But he also urged people to allow the inquiry to run its course "for the sake of the next of kin of the loved ones of MH370 who would be anxiously awaiting news and who have suffered much over this time".
An Australian-led search effort for the plane has so far focused on a vast area of the southern Indian Ocean about 4,000km (2,500 miles) to the east of Reunion.
No physical trace of the aircraft had been found.

MH370: The deep-sea hunt for missing plane
Mr Liow earlier confirmed that the object found on a beach at St Andre on Wednesday was a wing flap from a Boeing 777 - the same type of aircraft as the one that vanished.
The piece has gone to mainland France, where investigators in the city of Toulouse will seek to establish if it came from MH370. They will begin their work this Wednesday.
Fragments of a suitcase found on the same beach are also to be examined.
Investigators believe MH370 veered off course on the way to Beijing and crashed into the sea - but they do not know why.


A man has told an inquiry how a friend gave him the thumbs up seconds before he was crushed by a falling tree.

John Phillips died aged 29 on land in Angus owned by the family of his life-long friend, David Cochrane.
Mr Phillips and Mr Cochrane were felling trees beside a road at Auchindorie Farm, near Kirriemuir, when the incident occurred on 14 March 2013.
A determination in the fatal accident inquiry will be published in the next two weeks.
Mr Cochrane told the inquiry at Forfar Sheriff Court that he had been operating a Caterpillar Telehandler machine which was attached to the trees they were cutting by a wire.
Mr Phillips, who worked as a tree cutter, used a chainsaw to cut the trees down.
The inquiry heard Mr Phillips was only trained to cut trees up to 380mm (15in) wide - but that the tree he was working on was 1,100mm (43in) wide.
However, a Forestry Commission expert said he had been using the correct tools and techniques.
The expert told the court the tree had fallen in an unexpected direction, landing directly on top of Mr Phillips, because a "hinge" piece of wood had been "compromised" during cutting.
Mr Cochrane, 32, said he had known Mr Phillips since childhood and their families had been friends for years.
Speaking of the moment his friend was killed, Mr Cochrane said: "The wire rope was attached to the tree quite high up.
"I was in the telehandler, which was attached to the other end of the wire, around 60 metres [197ft] away. He gave me the thumbs up and I began to move to pull the tree down towards me.
"Instead of coming towards me the tree broke away from the stump and fell the wrong way. There was no going back once it broke off - there's nothing you can really do and it could have fallen in any direction."
Mr Cochrane told the court that once the tree had broken Mr Phillips had tried to run away to get himself clear, but the tree had landed on top of him.
"I detached the rope and drove the Telehandler over and used it to lift the tree clear of John," he said.
"I was shouting to see if I got a response but when I got to him there was no pulse. I could see by the damage caused by the tree that there was nothing I could have done."
Sheriff Gregor Murray said he would give a written determination in the next two weeks.
He said: "These inquiries are not here to establish blame but to try to learn from it for the future if we can.
"It is clear from the evidence that this was a genuine tragedy which I don't think anything beyond Mr Phillips' actions could control."


Paddy Lacey celebrated his first League goal for Accrington as they overcame Portsmouth.

It was Pompey who started off the livelier with former Stanley winger Gary Roberts, one of five former Reds in the Portsmouth 18, having a great chance to open the scoring in the third minute when he got the ball unmarked to the left of the area but fired across goal and wide.
Chances were limited, with an off-target Michael Doyle diving header after 33 minutes the closest Portsmouth came to scoring.
Stanley's best first-half chance came in the 40th minute when Sean McConville's corner was headed against his own crossbar by Pompey defender Christian Burgess.
The home side took the lead six minutes after the restart when Lacey collected the ball 20 yards out and found the top corner of the net with a superb strike on his league debut.
Billy Kee fired straight at David Forde as Stanley looked for a second, while McConville weaved his way into the area but his strike again was easy for the Pompey goalkeeper.
Portsmouth pressed but failed to threaten keeper Aaron Chapman as Stanley celebrated a second successive win.

A vegan diet has put Neil Robertson "in the best nick of his career" as he seeks a second World Championship.

The Australian, 33, changed his diet after guidance from strict vegan Peter Ebdon and says his energy levels and concentration have improved.
Cups of coffee have been replaced by banana smoothies, with meat and animal-derived foods off the menu.
"I haven't prepared as well for a World Championship, or any tournament, as I have for this one," said Robertson.
Snooker's world tour has a cluster of players, including Aditya Mehta and Liam Highfield, who stick to a vegan diet, which typically consists of plant-based foods such as grains, beans, vegetables, fruits and nuts.
Robertson, champion in 2010, claims he feels "fantastic" since he acted on Ebdon's advice late last year.
His own research into athletes such as Carl Lewis, who lived on a vegan diet, also proved influential and good form, including a final defeat to Shaun Murphy at the Masters in January has followed.
"I've not looked back since," said Robertson, who says other players - such as Joe Perry - are monitoring his progress with a view to copying the move.

"I used to feel very tired during tournaments. I was drinking four or five coffees per day and felt I needed more. Now I'm able to practice an awful lot more without getting tired."
Ebdon, who won a gruelling 18-17 final against Stephen Hendry in 2002, takes a juicer and blender to events.
The vegan of four years said: "It's improved my game in every single area. My recovery times are much quicker. I just feel amazing all the time."


This was supposed to be a mission to monitor the ceasefire by a team from the Organisation for Security and Co-operation in Europe (OSCE).

We were told by the pro-Russian rebels, who guided us, and other journalists, that things were quiet in the village of Shyrokyne, near the strategic port city of Mariupol.
But within minutes of arriving, there are loud explosions.
A man lies seriously wounded on the ground. He's bleeding badly from the head.
We learn he's called Andrei and is a journalist working for Russia's military TV channel.
A member of the BBC's team starts to treat him. He's joined by two medics from the OSCE.
Andrei has lost a lot of blood and his body is shaking violently as he goes into shock.
A local woman is screaming hysterically, as blood stains the pavement outside the local shop where he's now lying, and the journalists brought to monitor this peace mission crowd around.
The three men treating Andrei manage to stem the bleeding, but there are then exchanges of gunfire nearby.
What sound like rocket propelled grenades are also fired.
There is no ceasefire here, even when the OSCE are in the village.
The BBC-OSCE team gets Andrei into an old green Soviet-era van, and he is driven away to the local hospital.
Later we learn he is still alive, but in a serious condition.
His colleague tells us that Andrei said he needed the toilet. When he walked behind the shop, we believe he triggered a booby trap.
It was a short walk that might have cost him his life, and it was a reminder of how volatile the ceasefire agreement is here.
Later we meet two elderly women who are still living in this village on the frontline. Their eyes quickly fill with tears - this is a common scene in eastern Ukraine.


A long-serving RSPCA inspector says an abandoned pony found on a remote country lane had suffered some of the worst neglect he has ever seen.

The young piebald cob was found on Thursday at Braceby, near Grantham, with a hind leg infested with maggots.
Inspector Ian Callingham said the pony had obviously been dumped and left to die, and had suffered terribly. The animal was put down.
The RSPCA wants to hear from anyone who saw anything.
Mr Callingham, who has been with the RSPCA for 25 years, said: "The location was extremely remote; there are no homes, farms or equestrian centres nearby, so it is clear this pony was deliberately left with no intention of return.
"Her left hind leg was severely swollen to twice the size, and three large, deep holes that were bleeding and covered in maggots were clearly visible.
"It was terrible to see this young pony clearly in a huge amount of pain."
He added: "The wounds had been sprayed with a purple antiseptic spray, which suggests the owner was aware of the injury, but clearly failed to seek appropriate veterinary advice.
"She had a good body condition and trimmed hooves, so it is likely the owner was overwhelmed by the injury and reluctant to seek further treatment, for whatever reason."
On advice of the vet, the pony was put down to end her severe pain and suffering.
The charity said a low market price has led to irresponsible owners abandoning horses.


An ex-football club executive accused of social media crimes in Dubai will have to spend Christmas in prison, after his case was adjourned until January.

Ex-Leeds United managing director David Haigh pleaded not guilty to cyber slander at a Dubai hearing on Monday.
Mr Haigh, 38, had been due to complete a two-year prison sentence in Dubai for financial misappropriation.
He says he could not have committed the alleged Twitter offence while in jail.
The authorities in Dubai and the investment bank at the centre of the social media complaint have both so far not commented on the matter.
The maximum penalty for cyber slander is three years in prison and a fine of up to £5,500.
The social media case was adjourned until 4 January. Mr Haigh's solicitor said his client will not seek bail as he is already under a sentence of deportation so would be considered a flight risk.
The Yorkshire-born solicitor and businessman had expected to return to the UK on 16 November, after serving 18 months behind bars.
He was originally arrested in Dubai on 18 May last year, when he was detained without charge for 14 months and had his worldwide assets frozen.
In August 2015, he was convicted of misappropriating items of monetary value from a position of trust from his former Dubai-based employer and sentenced to two years in prison - the majority of which he had already served.
Mr Haigh's lawyer says he is considering seeking a retrial of his criminal conviction.
The former vice-chairman of the Gulf Tories had said that after returning to the UK he would campaign for Britons unfairly imprisoned around the world.
The new complaint is from Mr Haigh's former employer, investment bank Gulf Finance House (GFH), and referred to remarks made on Twitter.
Mr Haigh was the deputy chief executive of GFH Capital Limited, a fully-owned subsidiary of GFH, before resigning on 10 March last year.
Mr Haigh strongly denies the latest allegations against him.
When contacted by the BBC, GFH Capital Limited declined to comment.
GFH is an investment bank headquartered in Bahrain with an office in Dubai that once owned Leeds United Football Club and continues to hold a 25% stake in the club.
Speaking to the BBC from his police cell last week, Mr Haigh said he felt scared, frightened and worried.
When asked if he sent the tweets in question from his @haighdavid account, he said: "Absolutely not. I was held in a jail in Dubai."
He insisted he did not have access to a computer.
Tweets on the account are written in the third person and the account description states it is "managed for ex Leeds Utd FC MD while he remains in a Dubai jail".
Local authorities have so far not commented on the case despite repeated requests from the BBC.
Radha Stirling, chief executive of British-based group Detained in Dubai - which helps foreigners abroad - warned the UAE judicial system was still in development and the burden of proof on the complainant or prosecution, is quite low.
Ms Stirling told the BBC: "Without necessary safeguards in place, this legislation is open to abuse by disgruntled parties or parties who have an alternative agenda.
"This can render the respondent stuck in the UAE until the matter is resolved."
She said in some cases that could take months or even years.
The UAE government has reported that millions of tweets are sent in the UAE every day by hundreds of thousands of users.
Strict and wide-reaching guidelines prohibit the publication of content "which is contrary to public morals, the principles of Islam and the social and moral welfare of the UAE".
Cyber crime laws were introduced in the UAE in 2012 to make it an offence to use the internet to mock or deride organisations and individuals.
Ms Stirling said the new laws have increased the number of queries from Britons in relation to slander accusations by 150% in the past year.
In March, an expat American was jailed for comments he made on Facebook.
The British Foreign Office confirmed that Mr Haigh is still in Dubai.
A Foreign Office spokesman said: "We have been providing assistance to a British national detained in Dubai since May 2014, including regular visits to check on his welfare."


Former Swansea City striker Ian Walsh says the club have to replace manager Bob Bradley immediately to have any chance of avoiding relegation.

Media playback is not supported on this device
Boxing Day's 4-1 home defeat by West Ham left Swansea four points adrift of safety in the Premier League.
Bradley took training on Tuesday and could still be in charge against Bournemouth on New Yea's Eve, but Walsh believes the American should go.
"You just feel he's out of his depth," Walsh told BBC Radio Wales.
"He's not up to it, he's not aware of what needs to be going on.
"Yes, the players have to take a lot of responsibility but the buck stops with the man at the top. He's failed at what he's tried to achieve."
Swansea fans called for the American to be sacked during the defeat to West Ham, his seventh loss in 11 games since succeeding Francesco Guidolin in October.
Prior to the West Ham match, Bradley had admitted his future could depend on the outcome of the Boxing Day fixture and the home match with Bournemouth.
But after the loss against the Hammers, it is understood Swansea-based chairman Huw Jenkins is in touch with owners Jason Levien and Steve Kaplan in the USA.
Ex-Wales international Walsh, who spent two years at Swansea between 1982 and 1984, says American owners Jason Levien and Steve Kaplan need to replace their compatriot.
"I think this can only go one way and that would be relegation, so something has to be done," Walsh added.
"The American owners have given the American manager the chance and that's naïve to say the least.
"The owners have got to say 'we've given you an opportunity and it's not working.'
"They've got to get rid of Bob Bradley very, very quickly and bring somebody else in.
"The American owners have got to stand up, be counted and put their money where their mouth is and give someone the opportunity to see if they can drag Swansea out of the mire."
Another former Swansea City player, Owain Tudur Jones, also believes Bradley's future at the club is in doubt after defeat by the Hammers.
"The pressure is building on Bob Bradley," Jones told BBC 5 live.
"He's been very unfortunate to take over a side that is struggling but that's generally how managers get the job.
"If anything the record has worsened since he's been at the club."


In exactly four years' time, Europe's biggest infrastructure project will open to the public.

Crossrail is a new railway line running from east to west across London. It sounds simple enough but this is a project on a scale that echoes the great Brunel himself.
It includes 26 miles of tunnels and we were lucky enough to go down a few, just to see how they are getting on.
I say lucky. You should try climbing down 50 metres of claustrophobic metal staircase in full safety gear and carrying all the camera kit.
The hole we disappeared down will eventually be the new Liverpool Street Crossrail station.
Our guide John, a man who also helped build the Channel Tunnel, took us past all the machines, beeping lorries, cherry pickers and men, away from the lights, down a dark tunnel which eventually just, erm, stops.
In a few weeks' time, he said, a 1,000-tonne machine will crunch through that wall. I tried to picture it, inching towards us through the clay. Spooky.
Then when it arrives, they'll put it on some rails, drag it to the other end of the site, and it will start gouging out the wall at the other end.
So you can picture it, they've actually used diggers and sprayed concrete mixed with steel fibres (known as Shotcrete) to hollow out most of the stations, and the tunnelling machines connect up all the holes.
The exceptions are Paddington, Canary Wharf and Woolwich stations, which are essentially massive concrete boxes sunk into the ground.
There are two big engineering problems they've had to overcome. The first is water pressure. As they dig out the clay, the water in the sand and gravel underneath starts pressing upwards. It's a bit like shaking a Coke bottle with the lid on.
They've had to find a way of relieving that pressure without all the water bursting through. In the same way that you'd open the Coke bottle bit by bit so you don't get soaked, they're relieving the water pressure bit by bit.
Secondly, they've had to make sure none of the very heavy, often listed buildings above start moving. There is no danger of anything falling down, we're told, but still, you could get cracks and stresses that you don't want.
The answer to that problem is simple. They push pipes, about the width of drain pipes, into the ground under the buildings. The pipes have little holes all along them. If a building moves (they are all being monitored 24 hours a day) then they squirt grout, about the thickness of a milkshake, through the pipes. It spills out and pushes the ground back up. We're only talking a millimetre or so.
Interestingly, they use a similar technique to keep the tower holding Big Ben upright. It sits right over the Jubilee tube line.
In total, eight tunnel-boring machines, each weighing 1,000 tonnes, are inching under the capital. Each contraption is so big that they have a canteen on board for the workers, and they have been named after important women, including the world's first computer programmer, Ada Lovelace, and Phyllis Pearsall, who's credited with inventing London's A to Z.
The machine heading towards the spot we were standing at is called Elizabeth. I'm sure you can work out why.
Next March, they're going to bring up around 3,000 skeletons from the graveyard at the old Bethlem (Bedlam) Hospital. The remains will be tested for two years, then reburied in consecrated ground. There had been fears about unearthing anthrax and the plague but they didn't materialise, luckily.
They're also bringing up around 30 Roman skulls.
Two-thirds of the spoil from all that digging is being shipped up to Essex to build Europe's biggest coastal nature reserve.
If you happen to be walking around London in the next four years, try to imagine those 1,000-tonne machines creeping around below your feet, complete with workers having a sarnie in the on-board canteen.

Head coach Shade Munro is sure Scotland will keep getting better with experience after completing their best Women's Six Nations since 2006.

The campaign ended with a 14-12 win over Italy, adding to another home success against Wales.
Scotland's previous win in the tournament came back in 2010.
"We've made it a real point to make sure that we are learning from each match, regardless of the result," said Munro.
"In the past, they have been beaten heavily and just brushed it under the carpet.
"But you need to look at the England games, the France games, and understand what they are doing and what we could do better."
Scotland have just one player on a professional contract, number eight Jade Konkel. However, several younger members of the squad are coming through Scottish Rugby's academy system.
"The understanding of the way we are trying to play is improving," said Munro, who took charge in the summer of 2015.
"It's not a quick fix. Playing in the World Cup qualifiers has helped prepare us this season and the players have learned from every game.
"They have really bought into what we are trying to do and they have looked after themselves well. The academy structure has certainly got them a lot fitter.
"It's going to be difficult to challenge England or France anytime soon. There's quite a difference. All we can do is keep focusing on what we are doing and keep on improving.
"It's a young team and they are keen, which is what you want as a coach."
Just as they did against Wales, Scotland recovered from the loss of two tries to come back and beat the Italians in Cumbernauld.
"We didn't start particularly well and it was the same against Wales," said Munro. "That's something we need to fix.
"It's not a case of not being up for the game but they get stage fright, almost.
"They almost need the opposition to score a try before thinking 'hang on a minute, we're going to lose this unless we do something about it'.
"The players want to do well. They are putting so much effort in.
"I'm not in this to lose games but I was under no illusions that it was going to be difficult. It's taken a couple of years to get to this stage where we are just managing to win.
"Hopefully, we can keep on improving and start winning by a bit more."


Two people have been rescued after their microlight aircraft ditched in the Cromarty Firth.

The coastguard service was alerted to the incident, just west of Invergordon, at about 14:15.
The RNLI lifeboat from Invergordon was launched and managed to recover the casualties. They were later winched on board a coastguard helicopter and taken to Raigmore Hospital in Inverness.
It is understood that their injuries are not life-threatening.


World number one Novak Djokovic says a recurring wrist injury has "taken its toll" after a "very busy and active" year.

Media playback is not supported on this device
The Serb, 29, was knocked out in the first round of the Rio Olympics tennis tournament by Juan Martin del Potro.
He also suffered a surprise defeat by Sam Querrey in the third round of this year's Wimbledon.
Djokovic has pulled out of the Cincinnati Masters, which starts on 14 August.
"I am very sad to announce that I won't be able to play this year in Cincinnati," he said.
"I have a recurring injury that has taken its toll on my body due to a very busy and active schedule this year.
"I have played many matches and I have to take some rest in order to heal."


Andrew Howard is Wycombe Wanderers chairman, a motor racing champion and an ice cream man.

And ever since he set foot in Adams Park, the club have stopped getting licked on a weekly basis.
In May last year, the Chairboys were 90 minutes away from dropping out of the Football League.
Now, they are in the League Two promotion places and chasing an unexpected return to the third tier.
The club, it seems, has direction and leadership, and most of it comes from a man who owns one of the country's largest ice cream companies.
"You go to grown-up dinner parties and they're all there with their proper jobs. Somebody says, 'what do you do?' I get to say, 'I make ice cream'," Howard told BBC Sport.
The 51-year-old milked cows for a living, before going into business with his wife 16 years ago, producing ice cream from the cattle on her family's farm.
Now they have two factories, in High Wycombe and Chester, and produce 150 million portions of ice cream a year.
The Wycombe players, like children handed the golden ticket, have taken on the lead role of Charlie to Howard's chocolate factory.
"The football lads have been up and it's classic Willy Wonka - they come and design and make their own ice cream. That camaraderie has great value," he said.
One of the varieties made by the players, called Trench Mud, was inspired by a trip to the Somme last year.
Howard, and manager Gareth Ainsworth, believe in developing their players off the pitch as much as on it, whether it be concocting unusual ice cream flavours or visiting World War I battlegrounds.
"I don't want any of my players ending up in trouble. I'd be devastated if any of my players got in the news for the wrong reasons," said Ainsworth, who led the Chairboys to their dramatic final-day relegation escape last season.
"We want to keep an honest, sensible group that have the edge to win football games."
Preston-born Howard does not just bring experience in the frozen confectionery industry to the table.
He started Beechdean Motorsport 12 years ago, and after taking to the wheel himself, he won the 2013 British GT3 championship.
"You talk about your dream job, and racing driving is not far off. It's absolutely awesome," said Ainsworth, with a touch of jealousy.
"I've been on a couple of track days and I've watched him drive, and wow, that's some fantastic skill. But he understands sport and sportsmen."
Ainsworth, 41, a former Wimbledon and QPR winger, is getting his first sustained crack at management with the Buckinghamshire side.
Last season, his first full campaign in charge, was racked with uncertainty over the club's Football League future and financial stability, but they won 3-0 at Torquay on the final day of the season to sort out the first bit.
And in July, a month after joining as a director, Howard, who is a Leeds supporter, stepped up to become chairman and has since voluntarily helped to run the fan-owned club.
"I joked one day that if Leeds ever got in the same league as Wycombe, I would buy a box," he recalled.
"In 2009, 20 minutes after Wycombe were promoted to League One, the chairman at the time called me and asked which box do I want?"
The Ainsworth-Howard combination has worked.
Wycombe have one of the smallest wage bills in the division, but are currently third in the table.
"Financial security is still at the top of the list," said Howard.
"But we don't want to be totally boring and say 'you can't go for promotion'. There's no point being so transfixed on it - so there has to be a compromise."
The five-year plan is to be a sustainable League One side.
Howard says he wants the supporters' trust to always have ownership of Adams Park, but believes a committed benefactor may be needed to ensure Wycombe's long-term future.
Could he be that man? He is open to it, as long as the fans would have him. But in the short-term there is the possibility of achieving something much more exciting.
"The elephant in the room 12 months ago was relegation. The elephant in the room now is promotion. It's crazy," said Ainsworth.
"What a fantastic story that has been and I have to give credit to my players and my chairman, even though he won't want it."
In the mean time, Howard continues to bathe himself in the thrill of living out his own fairytale - the speed-demon Willy Wonka who gets to run a football team.
"Every part of it is very serious to me. But I wouldn't say I wake up every morning and go to work," he said.
"There is no question I'm living every child's dream."


A man who was found with stab wounds in a crashed car and later died has been identified by police.

Timothy Smith, 45, from Staffordshire, died on Thursday of a stab wound. He had been found in a car on an industrial estate in Shepshed, Leicestershire.
Four people have been arrested and are being questioned about his murder.
Mr Smith's father Derek, from Oxfordshire, said his son was "kind, thoughtful and caring".
"He was a thoroughly good-hearted person," Mr Smith said.
"He was kind and thoughtful and tried to do his best in every aspect of his life, whether that was how he applied himself to work or how he developed and maintained friendships.
"Tim loved his mother dearly, and was extremely upset when she died last year.
Since her death, we have been in regular contact, even thought he was living in Staffordshire, and news that he too now has gone is so desperately and deeply sad for us all."
Three men aged 53, 20 and 17, and a woman, 53, have been arrested over the death.
Police found Mr Smith in a silver Ford Fiesta car that had crashed into a wall near an industrial estate off Gelders Hall Road in Shepshed.


Many schools in England are struggling to recruit head teachers, amid increasingly negative attitudes to the job, a report warns.

It is crucial to counter negative views of headship, the Future Leaders Trust report says.
More than a quarter (28%) of existing heads are planning to leave within five years, while younger heads are unwilling to take on the role, it adds.
The government said it was taking steps to address the problem.
The report draws on research conducted jointly with the Times Educational Supplement (TES) last year, which also suggests most heads expect to leave the job within 10 years.
Separate research suggests "a clear decline" in positive perceptions of the role, the report says.
In 2009 a survey by the National College of School Leadership suggested 92% of head teachers believed they had "a great job".
But last year, another survey of senior leaders indicated almost nine in 10 (87%) felt headship was less attractive than it had been five years ago.
And research from the National Governors Association with the TES suggested 43% of 4,383 schools that recruited senior staff in 2015 had struggled to find good candidates.
Headship is "associated with high levels of stress and workload", the report says, while schools in isolated or economically deprived areas find it particularly hard to recruit heads.
"Taking up a headship in a challenging school with a poor Ofsted judgement is seen as a career risk because failure to improve the school quickly may be seen as failure," it says.
"Unsurprisingly, it is disadvantaged students in areas with relatively few opportunities, in schools that must improve, who are most affected by these negative perceptions of headship."
Future Leaders Trust chief executive Heath Monk said the talent was out there "but many people need encouragement to understand they can step up".
"The solution is for existing heads to spot potential leaders in their schools and inspire them about headship," he said.
"That means correcting the negative perceptions about the job and talking up its possibilities."
Ofsted's chief inspector of schools, Sir Michael Wilshaw, said: "It is incumbent on all leaders to plan for succession and develop potential within their teams."
Another contributor, Prof John Howson, an expert in school recruitment, said headship would not become attractive until "it is accepted that leaders themselves need support and recognition for their work".
A Department for Education spokesman said high quality school leaders were essential to the government's vision "of educational excellence everywhere".
"We are making good progress towards this goal, with Ofsted rating 85% of schools as 'good' or 'outstanding' for leadership and management, as well as a head teacher vacancy rate of just 0.2%, but we are not complacent," he said.
"Our Talented Leaders initiative is placing outstanding head teachers into struggling schools, and the National Teaching Service will place 1,500 teachers and middle leaders in underperforming schools by 2020."


The UK government says it plans to significantly reduce subsidies paid to small-scale green power installations.

Under the proposals, the amount of money paid to home owners and businesses producing electricity from roof-top solar and small wind turbines will be limited from January 2016.
Subsidy schemes could be closed to new entrants from the start of next year.
Ministers want to ensure that consumers who pay for the schemes through their bills get the best deal possible.
They admitted in July that spending on renewable energy schemes was set to be higher than expected.
Having already announced plans to limit cash paid to on-shore wind generation and large-scale solar farms, the Department of Energy and Climate Change (DECC) is now proposing significant cutbacks for small-sized green energy producers.
Solar and wind energy installations of less than 5MW are supported by feed-in tariffs - schemes that pay producers a subsidy for the electricity they generate, plus a bonus for any electricity exported back to the national grid.
Under the new proposals, the amount to be paid from next year will fall to 1.63p per kilowatt hour from a current level of 12.92p for a new residential solar system.
The consultation says that government spending on feed-in tariffs should be limited to between Â£75m and Â£100m from 2016 to 2018/19.
But DECC warns that if that limit is breached then "the only alternative would be to end generation tariffs for new applicants as soon as legislatively possible," which is expected to be January next year.
The Solar Trade Association (STA) says the proposals are not good news and the idea that the scheme might end for new entrants could become a self-fulfilling prophecy.
"We regret that proposals to suddenly cut tariffs combined with the threat of closure of the scheme next January will spark a massive market rush," said Mike Landy from the STA.
"This is the antithesis of a sensible policy for achieving better public value for money while safeguarding the British solar industry."
In their risk assessment published with the proposals, the government acknowledges that there is a chance that the changes may result in "significantly reduced rates of deployment" but they expect the industry to prove resilient, and point to the fact that the UK has already exceeded installation levels for small-scale solar and wind that were expected by 2020.
This rapid uptake of the technologies over the past few years means there has been considerable overspend on tariffs, according to the government, and that has to be curtailed.
"Our support has driven down the cost of renewable energy significantly," said a DECC spokesman.
"As costs continue to fall and we move towards sustainable electricity investment, it becomes easier for parts of the renewables industry to survive without subsidies. The consultation launched today is the next part of the action we promised to take to ensure bill payers get the best deal possible".
Environmental groups were not impressed.
Greenpeace pointed out that the government's maximum additional spend on green technologies by 2018 would be approximately half of what it spends subsidising the coal industry.
Other groups called the changes "absurd".
"Of course the feed-in tariff should fall as solar becomes cheaper, but the government clearly plans to remove support entirely," said Alasdair Cameron from Friends of the Earth.
"This is politically motivated, and will take away power from people and hand it back to big energy firms."
The consultation period on the proposed changes will run until 23 October.

The Tsukiji fish market is probably the rudest place in Japan.

If you've got an image in your mind of cheery fish mongers bowing and wishing you the Japanese equivalent of "top of the morning", forget it.
You get pushed and shoved, told "you're in the way!" At every step you're nearly run down by a three-wheeled electric cart careening through the tiny alleyways.
The message is clear - if you don't work here you're not really welcome.
Nor is Tsukiji any sort of architectural gem. Anyone expecting a Japanese version of Istanbul's Grand Bazaar is going to be disappointed.
Tsukiji is a sprawling collection of corrugated iron sheds put up in the aftermath of the Great Kanto Earthquake. It's old, rundown, dirty and overcrowded.
But you don't come here for architecture. You come for the fish and in this Tsukiji really is like nowhere else.
Every fish you've ever heard of is traded here, and many you haven't. There are giant spider crabs from Russia, scallops and sea urchin, squid and octopus, oysters and crayfish, salmon roe and sea cucumber.
But what Tsukiji is really famous for is tuna. More giant Pacific and Atlantic bluefin tuna are traded here than anywhere else in the world.
The action starts a little after 4am. In a long refrigerated hall, hundreds of shiny black and silver tuna are laid out in neat rows.
Some are 1.5m (5ft) long and weigh over 200kg (441lbs). Men in blue overalls and wellington boots are bending over, pulling open the gills and peering inside. These are the wholesalers who have licences to bid in the morning auctions.
At 5am the auction bells start ringing. The auctioneers step on to small wooden stools and the bidding begins.
The pace is frenetic. Six auctions are going at once. One auctioneer shouts, two others chant and the nearest sounds like he is singing.
There are maybe 1,000 tuna laid out here, but it's all over in a matter of minutes. The 200kg monsters are hauled away on handcarts by their new owners.
At his shop, deep in the bowels of the market, Toichiro Iida is waiting as one of the huge tuna is hauled in.
Now the real work begins.
First the fish is carefully washed and scrubbed. A muscular young man picks up a terrifying-looking knife called a 'Maguro-Bocho'.
The blade is 1.5m long and extremely sharp. Still, it takes all his strength and the help of a colleague to cut through the fish. After each cut, the meat is carefully wiped clean with a white cloth.
The final delicate jointing is done by Iida-san himself. His customers call in their orders - 2kg for this one, 5kg another. Some customers turn up to watch in person.
"Our customers trust me," Iida-san tells me.
"My eyes, my skill to find the fish which they like. If they come here I want to explain how it is, where it was caught, how it was caught, what it will taste like."
Carefully Iida-San takes another knife - this one the size of a samurai sword. In one smooth movement slices through the meat. Each joint is again carefully wiped with another fresh white cloth.
Finally the meat is gift-wrapped in dark green tissue paper, packed in ice, and dispatched to the customer. By lunchtime it will be served at the most expensive sushi restaurants in nearby Ginza.
Iida-san's family has been doing this for eight generations. In the 1850s, when the shoguns still ruled Japan, his forebears had a shop in the old fish market near Nihonbashi bridge.
That was destroyed in the Great Kanto Earthquake of 1923. In 1935, his grandfather moved to the new Tsukiji market.
Now they have been told to move again, across Tokyo Bay to an artificial island that used to be home to a chemical plant. The new market is beautiful, with vast white air-conditioned halls.
But no one is happy. For Iida-San, it's too far from his customers.
"I don't want to move. Ginza has 200 sushi shops. That culture was made by this place because we are close. It's only a 10-minute walk from there to this market," he says.
The new site is also contaminated. The old chemical plant seriously polluted ground water beneath the new market.  It was supposed to have been cleaned up.
But Tokyo's recently elected governor, Yuriko Koike, ordered new tests. Those have found benzene levels 79 times higher than government safety limits.
"I find myself with a renewed sense of surprise at how things have turned out," the chairman of the Tsukiji Market Association, Hiroyasu Ito, told the Kyodo news agency.
That's a bit of Japanese understatement. The site of the new market was supposed to have been covered with a thick layer of clean soil before construction began. Now it turns out that was never done.
Some fish wholesalers say they suspect the old Tokyo administration may have altered data in the original ground water tests in order to get the market move approved.
For the traders, it means more waiting and more uncertainty.
On the day I visit Tsukiji, it's supposed to be the last New Year auction ever to be held here. There's always excitement for the first big auction of the year, mainly because of the antics of one man.
Kiyoshi Kimura is the president of Japan's most successful sushi chain. Each January the rotund figure of Mr Kimura can be seen pushing the bids to astonishing levels.
In 2013 he paid over $1.7m (Â£1.4m) for a single 222kg bluefin. This year the bidding is a little more modest. He manages to net a 212kg fish for just 74 million yen ($652,000, Â£538,000).
At that price Mr Kimura is making a massive loss on every piece of sushi from the fish. Of course, it's a publicity stunt. His astronomic bids gain him headlines across Japan and around the world.
For some watching from the sidelines, Mr Kimura's annual stunt is in poor taste.
The world's appetite for bluefin tuna is running far ahead of the fish's ability to reproduce. Latest estimates suggest that since the 1960s stocks of Atlantic bluefin have fallen by over 95%.
The Pacific bluefin was thought to be in better shape, but recent surveys suggest it too is in deep trouble.
Attempts have been made in the United Nations to impose a temporary ban on catching Atlantic bluefin to allow the stocks to recover. But Japan and its allies have blocked them.
Toichiro Iida has seen the effect.
"When I started working in this market every day at the auction we had maybe 5,000 frozen tuna and 2,000 to 2,500 fresh tuna.
But now we have 1,000 or less frozen tuna each day, and fresh tuna is 200 or 100 or less. We don't have enough fish to sell to our customers."
I ask him if he now fears for the future of his business.
"Yes," he says, nodding his head vigorously. "I think maybe it's going to be like what happened to the whale."


A campaign to tackle the use of so-called legal highs is beginning following concerns about increased use.

Sands Cymru, Drugaid Cymru and Dash, are launching an initiative on Wednesday to tackle the problem.
Sands Cymru chief executive Ifor Glyn said: "This is not a problem that's going to go away anytime soon."
Public Health Wales has previously noted a "substantial escalation" in use since 2010.
Sands said the blanket ban on legal highs, also known as new psychoactive substances (NPS) proposed by the Westminster government was not going to halt the spread.
Concerns about the substances include people not knowing what they contain, a lack of understanding about their effects and how strong they are.
Thaker Hafid, a father-of-three from Cardiff, died in February after taking a legal high that was five times stronger than heroin.
The project, being launched in Neath, Neath Port Talbot, will offer briefings across Wales with the aim of reaching more than 8,000 people by Christmas.
Public Health Wales has also warned about a potentially dangerous legal high currently in circulation.
A man was taken to hospital in north Wales on 15 June after taking MMB-CHMINACA (MDMD-CHMICA) which has been associated with six deaths across Europe since September 2014.


The stars of One Direction have filmed a video message and offered to meet a teenage girl whose leg was amputated following a rollercoaster crash at Alton Towers.

Leah Washington, 17, from Barnsley, South Yorkshire, was one of five people who suffered severe injuries on the Smiler ride on 2 June.
A Twitter campaign - #Get1DToLeah - called for the pop band to contact her.
Friends said Ms Washington would be "elated" at the news.
Sara Stuart, who helped start the campaign, said she had been to the Royal Stoke Hospital to visit the teenager, whom she described as a huge fan of the band.
"She's seen them so many times," Ms Stuart said.
"It's really given Leah something to aim for and really look forward to once she's recovered."
The campaign has received thousands of retweets.
"The support has been overwhelming. It made me so happy that so many people were supporting one of my closest friends."
She said the message "would make Leah's day and aid her recovery".
She added her friend had tickets to see the band in concert in Cardiff on Saturday but was unable to go because of her injuries.
The band are currently in Europe as part of a world tour.
"After visiting her yesterday and knowing how upset she was that she missed seeing them on Saturday, we decided we would try and get in touch with them to see if they were prepared to visit her or send her a video message," she said.
"She would love this."
The band's agents said the band's four members - Niall Horan, Liam Payne, Harry Styles and Louis Tomlinson - had filmed a video message for Ms Washington.
"Unfortunately because of their schedule they can't visit her in hospital, but they have offered Leah tickets to a forthcoming concert of her choice when she has recovered, and will be delighted to meet her backstage then," they said.
Band member Louis Tomlinson has already sent her his best wishes.
He said he was thinking about her and hoping she was back home soon.
Ms Washington's boyfriend, 18-year-old Joe Pugh, from Barnsley, is being treated for two broken knees and "extensive" hand injuries at the Royal Stoke University Hospital.
The couple were in the front row of the Smiler ride, alongside Daniel Thorpe and Vicky Balch, when it hit an empty carriage last week.
Chanda Chauhan, 49, from Wednesbury, who was sitting in the second row of the ride, was taken to hospital with internal injuries.
The crash left 16 people trapped 25ft (7.6m) above the ground for about four-and-a-half hours.


Now Jaguar has unveiled its new electric car there's a huge battle just starting over the batteries that will power it.

At WMG, formerly the Warwick Manufacturing Group, based on the University of Warwick campus, researchers are working hard to make sure it's British battery technology that triumphs.
And right now we have a small lead but there's still fierce competition from overseas competitors.
So what happens at WMG's rapidly expanding battery lab is vital to the future of Jaguar and, of course, Coventry and the wider Midlands.
I went to see what the researchers are up to.
What's really fascinating for a scientist like me is the scale of this lab.
It's much bigger than your standard university laboratory.
Here they don't just come up with new battery recipes or test them to destruction.
They have all the machines necessary to scale things up and produce actual batteries on a mini production line.
For example; prototype lithium oxide batteries react badly to water and must be produced in a protective atmosphere.
In a university lab that means using a small sealed box where the researcher can stick her hands inside using gloves built into the box itself.
At WMG it's all on a much bigger scale.
You enter an airlock and then an entire room where all troublesome water is removed from the atmosphere.
In fact, the air is 20 times drier inside this room than it is in the Sahara.
Things at the battery lab are getting even bigger, with a £20m extension.
So after all this money and effort, have the team managed to improve things?
Well yes.
They believe they can create a vehicle battery that is an 80% improvement on current battery technologies. (Full disclosure: That's not an 80% increase in efficiency or an 80% increase in power to weight ratio, but rather an overall comparison involving all these measurements and more).
What's really exciting is that the size of the WMG battery lab means they can take this new battery and scale up production.
It is to see if it can be made using actual production techniques that would be found in a factory and at a size where it could be fitted to an electric car.
It means an electric car using this new battery could be tested as early as next year.
Which is of great interest to Jaguar and its newly announced electric car plans.

More Native Americans are participating in the 2016 election than ever before.

Eight indigenous candidates are running for Congress, up from two in 2014. Over 90 are running for state legislatures, again exceeding previous years.
Hillary Clinton ran campaign ads in Navajo and met with tribal leaders in Iowa, Washington, Arizona and California during the presidential primaries. Bernie Sanders met with 90 leaders in total, a political record.
"This is the best campaign ever in Indian Country," says Nicole Willis, member of the Confederated Tribes of Umatilla and former advisor to Bernie Sanders. "There's no question about that."
Native Americans, who make up approximately 1.7% of the US population, are unlikely to determine a presidential election.
But they do play an important role in shaping local politics and swinging votes for seats in Congress.
Source: National Congress of American Indians
Almost 15% of Alaska's population is indigenous, which played an important part in bringing Senator Lisa Murkowski to victory in 2010. Local districts of North Dakota, New Mexico and other Western states have large and in some cases majority Native American populations.
"Tribes are organised entities that tend to vote as a group," says John Dossett, General Counsel within the National Congress of American Indians. "When they turn up and vote in one block, they can have a huge impact at a state level."
Mark Trahant, former president of the Native American Journalists Association, believes indigenous votes could strip Republicans of as many as six Congressional seats come election time in November.
"Montana is one of the most important states," he says.  Denise Juneau, a member of the Mandan Hidatsa Tribes, is running for Senate there. "She's raised a lot of money. It could be tight race with [Republican] Ryan Zinke."
Why is 2016 proving to be such a vibrant year for indigenous politics?
Many Native American commentators point to President Barack Obama's efforts to improve relations with the country's tribal nations.
In the course of his two terms in office, he has settled hundreds of legal disputes with indigenous communities, passed favourable legislation, like the Indian Health Care Improvement Act, and established an annual conference for tribal leaders to meet at the White House.
Ties between the federal government and many Native American communities, some of whom were denied the vote until the 1950s, have never been better.
"Obama's commitment to young natives in particular has had a tremendous impact," says Erik Stegman, executive director of the Center for Native American Youth. "We've seen a lot of interest in this election and a large number campaigning for Hilary Clinton and Bernie Sanders."
Close to 32% of Native Americans are under the age of 18. Government-funded programmes, like Generation Indigenous, which seeks to empower native millennials, have been battling to inspire this age group for years.
"The US political system was not designed for us," says Jaynie Parrish, an advisor to Barack Obama during his 2012 campaign and a member of the Navajo nation. "Getting young people involved is incredibly difficult. But we are learning to play the game."
Except for pockets of Republican support in Arizona, Nevada and a significant following in Oklahoma, Native Americans are overwhelmingly Democrats. Close to 70% voted for Barak Obama in 2012.
Of the 94 indigenous candidates running for office this year, 75 are Democrats, 14 are Republicans and four are independent.
The Democratic party has almost 150 native delegates, who have stake in electing presidential nominees during the primary voting stage.
During the Democratic Convention in Philadelphia, these individuals played a visible role in proceedings, calling out state votes in the nomination process and speaking on the opening day of the ceremony.
At the Republican Convention in Cleveland, only one Native American delegate represented the party.
Among Native communities, Republican nominee Donald Trump is widely regarded as a threatening figure.
While speaking on a radio show in 1993, he said "I think I might have more Indian blood than a lot of the so-called Indians," referring to native people he was competing with in the casino industry at the time.
In February 2000, Trump paid over $1m (Â£774,000) for negative advertisements depicting the St Regis Mohawk people in New York State as "criminals."
During this year's presidential campaign, he has repeatedly referred to Senator Elizabeth Warren as "Pocahontas," mocking her claim to have distant Native American ancestry.
'We have a lot of fear as to what he might do," says Arlan Melendez, member of the National Congress of American Indians and Chairman of the Reno Sparks Indian Colony. "I haven't met one tribe out of all 567 that has said they will support Trump."
Despite the increased enthusiasm of native voters, challenges remain.
Communities living in remote areas, like the Goshute reservation in Utah, will have to travel as far as 140 miles to reach their nearest polling station on election day on 8 November.
Language barriers, polling closures and voting identification requirements hinder Native American election participation in many other areas.
"We are having to deal with a colonial legacy that was intended to exclude us," said Chase Iron Eyes, a member of the Standing Rock Sioux Tribe running for the House of Representatives in North Dakota.
"A lot of people think we were all killed, that the Americans and Europeans wiped us out. But we are still here."
