Wells Dry, Fertile Plains Turn to Dust

HASKELL COUNTY, Kan. — Forty-nine years ago, Ashley Yost’s grandfather sank a well deep into a half-mile square of rich Kansas farmland. He struck an artery of water so prodigious that he could pump 1,600 gallons to the surface every minute.

Last year, Mr. Yost was coaxing just 300 gallons from the earth, and pumping up sand in order to do it. By harvest time, the grit had robbed him of $20,000 worth of pumps and any hope of returning to the bumper harvests of years past.

“That’s prime land,” he said not long ago, gesturing from his pickup at the stubby remains of last year’s crop. “I’ve raised 294 bushels of corn an acre there before, with water and the Lord’s help.” Now, he said, “it’s over.”

The land, known as Section 35, sits atop the High Plains Aquifer, a waterlogged jumble of sand, clay and gravel that begins beneath Wyoming and South Dakota and stretches clear to the Texas Panhandle. The aquifer’s northern reaches still hold enough water in many places to last hundreds of years. But as one heads south, it is increasingly tapped out, drained by ever more intensive farming and, lately, by drought.

Vast stretches of Texas farmland lying over the aquifer no longer support irrigation. In west-central Kansas, up to a fifth of the irrigated farmland along a 100-mile swath of the aquifer has already gone dry. In many other places, there no longer is enough water to supply farmers’ peak needs during Kansas’ scorching summers.

And when the groundwater runs out, it is gone for good. Refilling the aquifer would require hundreds, if not thousands, of years of rains.

This is in many ways a slow-motion crisis — decades in the making, imminent for some, years or decades away for others, hitting one farm but leaving an adjacent one untouched. But across the rolling plains and tarmac-flat farmland near the Kansas-Colorado border, the effects of depletion are evident everywhere. Highway bridges span arid stream beds. Most of the creeks and rivers that once veined the land have dried up as 60 years of pumping have pulled groundwater levels down by scores and even hundreds of feet.

On some farms, big center-pivot irrigators — the spindly rigs that create the emerald circles of cropland familiar to anyone flying over the region — now are watering only a half-circle. On others, they sit idle altogether.

Two years of extreme drought, during which farmers relied almost completely on groundwater, have brought the seriousness of the problem home. In 2011 and 2012, the Kansas Geological Survey reports, the average water level in the state’s portion of the aquifer dropped 4.25 feet — nearly a third of the total decline since 1996.

And that is merely the average. “I know my staff went out and re-measured a couple of wells because they couldn’t believe it,” said Lane Letourneau, a manager at the State Agriculture Department’s water resources division. “There was a 30-foot decline.”

Kansas agriculture will survive the slow draining of the aquifer — even now, less than a fifth of the state’s farmland is irrigated in any given year — but the economic impact nevertheless will be outsized. In the last federal agriculture census of Kansas, in 2007, an average acre of irrigated land produced nearly twice as many bushels of corn, two-thirds more soybeans and three-fifths more wheat than did dry land.

Farmers will take a hit as well. Raising crops without irrigation is far cheaper, but yields are far lower. Drought is a constant threat: the last two dry-land harvests were all but wiped out by poor rains.

In the end, most farmers will adapt to farming without water, said Bill Golden, an agriculture economist at Kansas State University. “The revenue losses are there,” he said. “But they’re not as tremendously significant as one might think.”

Some already are. A few miles west of Mr. Yost’s farm, Nathan Kells cut back on irrigation when his wells began faltering in the last decade, and shifted his focus to raising dairy heifers — 9,000 on that farm, and thousands more elsewhere. At about 12 gallons a day for a single cow, Mr. Kells can sustain his herd with less water than it takes to grow a single circle of corn.

“The water’s going to flow to where it’s most valuable, whether it be industry or cities or feed yards,” he said. “We said, ‘What’s the higher use of the water?’ and decided that it was the heifer operation.”

The problem, others say, is that when irrigation ends, so do the jobs and added income that sustain rural communities.

“Looking at areas of Texas where the groundwater has really dropped, those towns are just a shell of what they once were,” said Jim Butler, a hydrogeologist and senior scientist at the Kansas Geological Survey.

The villain in this story is in fact the farmers’ savior: the center-pivot irrigator, a quarter- or half-mile of pipe that traces a watery circle around a point in the middle of a field. The center pivots helped start a revolution that raised farming from hardscrabble work to a profitable business.

Since the pivots’ debut some six decades ago, the amount of irrigated cropland in Kansas has grown to nearly three million acres, from a mere 250,000 in 1950. But the pivot irrigators’ thirst for water — hundreds and sometimes thousands of gallons a minute — has sent much of the aquifer on a relentless decline. And while the big pivots have become much more efficient, a University of California study earlier this year concluded that Kansas farmers were using some of their water savings to expand irrigation or grow thirstier crops, not to reduce consumption.

A shift to growing corn, a much thirstier crop than most, has only worsened matters. Driven by demand, speculation and a government mandate to produce biofuels, the price of corn has tripled since 2002, and Kansas farmers have responded by increasing the acreage of irrigated cornfields by nearly a fifth.

At an average 14 inches per acre in a growing season, a corn crop soaks up groundwater like a sponge — in 2010, the State Agriculture Department said, enough to fill a space a mile square and nearly 2,100 feet high.

Sorghum, or milo, gets by on a third less water, Kansas State University researchers say — and it, too, is in demand by biofuel makers. As Kansas’ wells peter out, more farmers are switching to growing milo on dry land or with a comparative sprinkle of irrigation water.

But as long as there is enough water, most farmers will favor corn. “The issue that often drives this is economics,” said David W. Hyndman, who heads Michigan State University’s geological sciences department. “And as long as you’ve got corn that’s $7, then a lot of choices get made on that.”

Of the 800 acres that Ashley Yost farmed last year in Haskell County, about 70 percent was planted in corn, including roughly 125 acres in Section 35. Haskell County’s feedlots — the county is home to 415,000 head of cattle — and ethanol plants in nearby Liberal and Garden City have driven up the price of corn handsomely, he said.

But this year he will grow milo in that section, and hope that by ratcheting down the speed of his pump, he will draw less sand, even if that means less water, too. The economics of irrigation, he said, almost dictate it.

“You’ve got $20,000 of underground pipe,” he said. “You’ve got a $10,000 gas line. You’ve got a $10,000 irrigation motor. You’ve got an $89,000 pivot. And you’re going to let it sit there and rot?

“If you can pump 150 gallons, that’s 150 gallons Mother Nature is not giving us. And if you can keep a milo crop alive, you’re going to do it.”

Mr. Yost’s neighbors have met the prospect of dwindling water in starkly different ways. A brother is farming on pivot half-circles. A brother-in-law moved most of his operations to Iowa. Another farmer is suing his neighbors, accusing them of poaching water from his slice of the aquifer.

A fourth grows corn with an underground irrigation system that does not match the yields of water-wasting center-pivot rigs, but is far thriftier in terms of water use and operating costs.

For his part, Mr. Yost continues to pump. But he also allowed that the day may come when sustaining what is left of the aquifer is preferable to pumping as much as possible.

Sitting in his Ford pickup next to Section 35, he unfolded a sheet of white paper that tracked the decline of his grandfather’s well: from 1,600 gallons a minute in 1964, to 1,200 in 1975, to 750 in 1976.

When the well slumped to 500 gallons in 1991, the Yosts capped it and drilled another nearby. Its output sank, too, from 1,352 gallons to 300 today.

This year, Mr. Yost spent more than $15,000 to drill four test wells in Section 35. The best of them produced 195 gallons a minute — a warning, he said, that looking further for an isolated pocket of water would be costly and probably futile.

“We’re on the last kick,” he said. “The bulk water is gone.” More

Signs of stress must not be ignored, IEA warns in its new World Energy Outlook

Energy sector must tackle longer-term pressure points before they reach breaking point

Events of the last year have increased many of the long-term uncertainties facing the global energy sector, says the International Energy Agency’s (IEA) World Energy Outlook 2014 (WEO-2014). It warns against the risk that current events distract decision makers from recognising and tackling the longer-term signs of stress that are emerging in the energy system.

In the central scenario of WEO-2014, world primary energy demand is 37% higher in 2040, putting more pressure on the global energy system. But this pressure would be even greater if not for efficiency measures that play a vital role in holding back global demand growth. The scenario shows that world demand for two out of the three fossil fuels – coal and oil – essentially reaches a plateau by 2040, although, for both fuels, this global outcome is a result of very different trends across countries. At the same time, renewable energy technologies gain ground rapidly, helped by falling costs and subsidies (estimated at $120 billion in 2013). By 2040, world energy supply is divided into four almost equal parts: low-carbon sources (nuclear and renewables), oil, natural gas and coal.

In an in-depth focus on nuclear power, WEO-2014 sees installed capacity grow by 60% to 2040 in the central scenario, with the increase concentrated heavily in just four countries (China, India, Korea and Russia). Despite this, the share of nuclear power in the global power mix remains well below its historic peak. Nuclear power plays an important strategic role in enhancing energy security for some countries. It also avoids almost four years’ worth of global energy-related carbon-dioxide (CO2) emissions by 2040. However, nuclear power faces major challenges in competitive markets where there are significant market and regulatory risks, and public acceptance remains a critical issue worldwide. Many countries must also make important decisions regarding the almost 200 nuclear reactors due to be retired by 2040, and how to manage the growing volumes of spent nuclear fuel in the absence of permanent disposal facilities.

“As our global energy system grows and transforms, signs of stress continue to emerge,” said IEA Executive Director Maria van der Hoeven. “But renewables are expected to go from strength to strength, and it is incredible that we can now see a point where they become the world’s number one source of electricity generation.”

The report sees a positive outlook for renewables, as they are expected to account for nearly half of the global increase in power generation to 2040, and overtake coal as the leading source of electricity. Wind power accounts for the largest share of growth in renewables-based generation, followed by hydropower and solar technologies. However, as the share of wind and solar PV in the world’s power mix quadruples, their integration becomes more challenging both from a technical and market perspective.

World oil supply rises to 104 million barrels per day (mb/d) in 2040, but hinges critically on investments in the Middle East. As tight oil output in the United States levels off, and non-OPEC supply falls back in the 2020s, the Middle East becomes the major source of supply growth. Growth in world oil demand slows to a near halt by 2040: demand in many of today’s largest consumers either already being in long-term decline by 2040 (the United States, European Union and Japan) or having essentially reached a plateau (China, Russia and Brazil). China overtakes the United States as the largest oil consumer around 2030 but, as its demand growth slows, India emerges as a key driver of growth, as do sub-Saharan Africa, the Middle East and Southeast Asia.

“A well-supplied oil market in the short-term should not disguise the challenges that lie ahead, as the world is set to rely more heavily on a relatively small number of producing countries,” said IEA Chief Economist Fatih Birol. “The apparent breathing space provided by rising output in the Americas over the next decade provides little reassurance, given the long lead times of new upstream projects.”

Demand for gas is more than 50% higher in 2040, and it is the only fossil fuel still growing significantly at that time. The United States remains the largest global gas producer, although production levels off in the late-2030s as shale gas output starts to recede. East Africa emerges alongside Qatar, Australia, North America and others as an important source of liquefied natural gas (LNG), which is an increasingly important tool for gas security. A key uncertainty for gas outside of North America is whether it can be made available at prices that are low enough to be attractive for consumers and yet high enough to incentivise large investments in supply.

While coal is abundant and its supply relatively secure, its future use is constrained by measures to improve efficiency, tackle local pollution and reduce CO2 emissions. Coal demand is 15% higher in 2040 but growth slows to a near halt in the 2020s. Regional trends vary, with demand reaching a peak in China, dropping by one-third in the United States, but continuing to grow in India.

The global energy system continues to face a major energy poverty crisis. In sub-Saharan Africa (the regional focus of WEO-2014), two out of every three people do not have access to electricity, and this is acting as a severe constraint on economic and social development. Meanwhile, costly fossil-fuel consumption subsidies (estimated at $550 billion in 2013) are often intended to help increase energy access, but fail to help those that need it most and discourage investment in efficiency and renewables.

A critical “sign of stress” is the failure to transform the energy system quickly enough to stem the rise in energy-related CO2 emissions (which grow by one-fifth to 2040) and put the world on a path consistent with a long-term global temperature increase of 2°C. In the central scenario, the entire carbon budget allowed under a 2°C climate trajectory is consumed by 2040, highlighting the need for a comprehensive and ambitious agreement at the COP21 meeting in Paris in 2015.

Sifting through the wreckage of MH17, searching for sense amid the horror

Any journalist should hesitate before saying this, but news can be bad for you. You don’t have to agree with the analyst who reckons “news is to the mind what sugar is to the body” to see that reading of horror and foreboding hour by hour, day after day, can sap the soul.

This week ended with a double dose, administered within the space of a few hours: Israel’s ground incursion into Gaza and, more shocking because entirely unexpected, the downing of Malaysia Airlines flight MH17 over Ukraine, killing all 298 on board.

So in Gaza we look at the wildly lopsided death tolls – nearly 300 Palestinians and two Israelis killed these past nine days.

The different responses these events stir in those of us who are distant, and the strategies we devise to cope with them, say much about our behaviour as consumers of news. But they also go some way to determining our reaction as citizens, as constituent members of the amorphous body we call public, or even world, opinion.

As I write, 18 of the 20 most-read articles on the Guardian website are about MH17. The entry into Gaza by Israeli forces stands at number 21. It’s not hard to fathom why the Malaysian jet strikes the louder chord. As the preacher might put it, “There but for the grace of God go I.” Stated baldly, most of us will never live in Gaza, but we know it could have been us boarding that plane in Amsterdam.

Which is why there is a morbid fascination with tales of the passenger who changed flights at the last minute, thereby cheating death, or with the crew member who made the opposite move, hastily switching to MH17 at the final moment, taking a decision that would have seemed so trivial at the time but which cost him his life. When we read about the debris – the holiday guidebooks strewn over the Ukrainian countryside, the man found next to an iPhone, the boy with his seatbelt still on – our imaginations put us on that flight. Of course we have sympathy for the victims and their families. But our fear is for ourselves.

It’s quite true that if the US truly decided that Israel’s 47-year occupation of Palestinian territory was no longer acceptable, that would bring change.

The reports from Gaza stir a different feeling. When we read the Guardian’s Peter Beaumont describe the sights he saw driving around the strip on Friday morning – three Palestinian siblings killed by an Israeli artillery shell that crashed into their bedroom, a father putting the remains of his two-year-old son into a plastic shopping bag – we are shaken by a different kind of horror. It is compassion for another human being, someone in a situation utterly different to ours. We don’t worry that this might happen to us, as we now might when we contemplate an international flight over a war zone. Our reaction is directed not inward, but outward. More

There is an interesting article by Chris Hedges entitled It's NOT going to be OK on the current economic disparity which, he believes could lead to a drastic decline in democracy as states respond to social protests. The question I ask is what can be done to slow or erradicate this process? Editor

The Peak Oil Crisis: Better Than Fire

In addition to following the twists and turn of the world’s energy situation, I have been tracking the reporting on developments concerning several “exotic” and therefore controversial energy sources whose proponents say would be far more cost-effective than current alternatives to fossil fuels such as wind, solar and nuclear.

The reason for this interest is that if one believes global warming is caused by carbon emissions, then it certainly looks like there will not be much left of human civilization in a century or so. While the use of “conventional” alternatives is growing, the demand for energy to fuel economic growth is so great that it seems likely that, unless some outside force intervenes, mankind is going to burn fossil fuels until it is no longer economically possible to do so.

What is clearly necessary is some source of energy that is so cheap and easy to produce and so environmentally clean that everyone on earth will want to use the new energy source as soon as possible.

Fortunately, there are a handful of people out there who really are a few steps ahead of academia, government officials, and the mainstream media in the effort to save mankind from what is shaping up to be a many millennia-long disaster. In the past I have written about cold fusion or in the current jargon, low energy nuclear reactions (LENR). This technology is still alive, well, and seems destined to produce some commercially viable prototypes in the near future.

However, last week a company up in New Jersey call BlackLight Power and its founder announced a breakthrough which could be just what the world sorely needs in addition to touching off a new era in the history of mankind. I stress could for all the evidence is not in yet and useful prototypes have yet to be built, but BlackLight’s founder and inventor of the technology, Randall Mills, seems unusually forthright in his claims that there has indeed been a breakthrough on the exotic energy front. For those of the “its too good to be true” bent, keep in mind that discoveries do happen from time to time – electricity, internal combustion, and smart phones to name a few.

About 20 years ago Randall Mills announced that a more compact form of the hydrogen atom existed in the universe which he termed a hydrino. This form of hydrogen had its electron circling its proton at about 1/4th the distance from the nucleus as in a conventional hydrogen atom and therefore had much less energy. Mills went on to say he believed that the dark matter which makes up the bulk of the universe was composed of these compact hydrogen atoms which neither absorb nor emit light making them very difficult to detect. At the cosmological scale dark matter is only known to exist because of its gravitational pull on other mass. As most of the visible universe is composed of hydrogen, it seems to make sense that the invisible part is hydrogen too.

When Mills announced his hypothesis in 1991, it was, of course, denounced by the scientific establishment as ridiculous for if another form of hydrogen existed, we surely would have discovered it decades ago. To make the ensuing controversy still worse, Mills claimed that the accepted version of quantum mechanics had it wrong in its description of just what an electron is and that the classical physics of Newton and Maxwell works at the atomic as well as the cosmic scale. Such a claim is heresy of the first order in the land of the scientists so Mills and his hydrinos were quickly forgotten.

From mankind’s perspective, however, the interesting feature about the existence of two forms of hydrogen is that in converting the conventional hydrogen atom to a hydrino a spectacular amount of energy is released – on the order of 200 times as much as when hydrogen is joined with oxygen to form H2O. Thus began the 20-year search for the Holy Grail of our civilization – a way to transform hydrogen into hydrinos and release lots of energy.

As with the Wright brothers, all Mills had to do was to build a machine that took in water and send commerical amounts of energy out, then his thesis would have to be accepted. It took 20+ years to develop the theoretical basis for such a machine, but for the last six months Mills has been demonstrating crude prototypes to selected audiences. Fortunately for the rest of us, these demonstrations and considerable information on what is taking place have been appearing regularly on the internet. Although some remain skeptical, the length of time Mills has been working on this project, the size of his organization, the scale of his financial backing and the verification of his science by external laboratories strongly suggests that his claims are valid.

Mills’ machines are remarkably simple. After 20 years of research he has developed a metallic powder that will also absorb moisture (hydrogen) from the humidity in the air. A tiny amount of this damp powder is subjected to a low voltage, high amperage current and the hydrogen in the powder is zapped, for want of a better word, into hydrinos with a blinding flash of light. The hydrogen-depleted powder can then absorb more moisture from the atmosphere and be reused indefinitely.

While the mini-explosions that take place in Mills’ device are spectacular, they certainly were a long ways from a technology that might save the world until two weeks ago when he announced that the energy emitted from these “explosions” is mostly white light. The white light emitted is at least 50,000 times brighter than that of sunlight as it reaches the earth’s surface and given the latest in solar cell technology, can easily be converted into prodigious amounts of electricity using only the humidity in the air as the fuel. One design is anticipating that a one-foot cubic device will be able to produce 10 million watts of electric power.

To quote Mills, “nature has just given us the best gift that we have ever had, this is better than fire.” More

How Saudi Arabia Helped Isis Take Over the North of Iraq

How far is Saudi Arabia complicit in the Isis takeover of much of northern Iraq, and is it stoking an escalating Sunni-Shia conflict across the Islamic world?

Some time before 9/11, Prince Bandar bin Sultan, once the powerful Saudi ambassador in Washington and head of Saudi intelligence until a few months ago, had a revealing and ominous conversation with the head of the British Secret Intelligence Service, MI6, Sir Richard Dearlove. Prince Bandar told him: “The time is not far off in the Middle East, Richard, when it will be literally ‘God help the Shia’. More than a billion Sunnis have simply had enough of them.”

The fatal moment predicted by Prince Bandar may now have come for many Shia, with Saudi Arabia playing an important role in bringing it about by supporting the anti-Shia jihad in Iraq and Syria. Since the capture of Mosul by the Islamic State of Iraq and the Levant (Isis) on 10 June, Shia women and children have been killed in villages south of Kirkuk, and Shia air force cadets machine-gunned and buried in mass graves near Tikrit.

In Mosul, Shia shrines and mosques have been blown up, and in the nearby Shia Turkoman city of Tal Afar 4,000 houses have been taken over by Isis fighters as “spoils of war”. Simply to be identified as Shia or a related sect, such as the Alawites, in Sunni rebel-held parts of Iraq and Syria today, has become as dangerous as being a Jew was in Nazi-controlled parts of Europe in 1940.

There is no doubt about the accuracy of the quote by Prince Bandar, secretary-general of the Saudi National Security Council from 2005 and head of General Intelligence between 2012 and 2014, the crucial two years when al-Qa’ida-type jihadis took over the Sunni-armed opposition in Iraq and Syria. Speaking at the Royal United Services Institute last week, Dearlove, who headed MI6 from 1999 to 2004, emphasised the significance of Prince Bandar’s words, saying that they constituted “a chilling comment that I remember very well indeed”.

He does not doubt that substantial and sustained funding from private donors in Saudi Arabia and Qatar, to which the authorities may have turned a blind eye, has played a central role in the Isis surge into Sunni areas of Iraq. He said: “Such things simply do not happen spontaneously.” This sounds realistic since the tribal and communal leadership in Sunni majority provinces is much beholden to Saudi and Gulf paymasters, and would be unlikely to cooperate with Isis without their consent.

Dearlove’s explosive revelation about the prediction of a day of reckoning for the Shia by Prince Bandar, and the former head of MI6′s view that Saudi Arabia is involved in the Isis-led Sunni rebellion, has attracted surprisingly little attention. Coverage of Dearlove’s speech focused instead on his main theme that the threat from Isis to the West is being exaggerated because, unlike Bin Laden’s al-Qa’ida, it is absorbed in a new conflict that “is essentially Muslim on Muslim”. Unfortunately, Christians in areas captured by Isis are finding this is not true, as their churches are desecrated and they are forced to flee. A difference between al-Qa’ida and Isis is that the latter is much better organised; if it does attack Western targets the results are likely to be devastating.

The forecast by Prince Bandar, who was at the heart of Saudi security policy for more than three decades, that the 100 million Shia in the Middle East face disaster at the hands of the Sunni majority, will convince many Shia that they are the victims of a Saudi-led campaign to crush them. “The Shia in general are getting very frightened after what happened in northern Iraq,” said an Iraqi commentator, who did not want his name published. Shia see the threat as not only military but stemming from the expanded influence over mainstream Sunni Islam of Wahhabism, the puritanical and intolerant version of Islam espoused by Saudi Arabia that condemns Shia and other Islamic sects as non-Muslim apostates and polytheists.

Dearlove says that he has no inside knowledge obtained since he retired as head of MI6 10 years ago to become Master of Pembroke College in Cambridge. But, drawing on past experience, he sees Saudi strategic thinking as being shaped by two deep-seated beliefs or attitudes. First, they are convinced that there “can be no legitimate or admissible challenge to the Islamic purity of their Wahhabi credentials as guardians of Islam’s holiest shrines”. But, perhaps more significantly given the deepening Sunni-Shia confrontation, the Saudi belief that they possess a monopoly of Islamic truth leads them to be “deeply attracted towards any militancy which can effectively challenge Shia-dom”.

Western governments traditionally play down the connection between Saudi Arabia and its Wahhabist faith, on the one hand, and jihadism, whether of the variety espoused by Osama bin Laden and al-Qa’ida or by Abu Bakr al-Baghdadi’s Isis. There is nothing conspiratorial or secret about these links: 15 out of 19 of the 9/11 hijackers were Saudis, as was Bin Laden and most of the private donors who funded the operation.

The difference between al-Qa’ida and Isis can be overstated: when Bin Laden was killed by United States forces in 2011, al-Baghdadi released a statement eulogising him, and Isis pledged to launch 100 attacks in revenge for his death.

But there has always been a second theme to Saudi policy towards al-Qa’ida type jihadis, contradicting Prince Bandar’s approach and seeing jihadis as a mortal threat to the Kingdom. Dearlove illustrates this attitude by relating how, soon after 9/11, he visited the Saudi capital Riyadh with Tony Blair.

He remembers the then head of Saudi General Intelligence “literally shouting at me across his office: ’9/11 is a mere pinprick on the West. In the medium term, it is nothing more than a series of personal tragedies. What these terrorists want is to destroy the House of Saud and remake the Middle East.’” In the event, Saudi Arabia adopted both policies, encouraging the jihadis as a useful tool of Saudi anti-Shia influence abroad but suppressing them at home as a threat to the status quo. It is this dual policy that has fallen apart over the last year.

Saudi sympathy for anti-Shia “militancy” is identified in leaked US official documents. The then US Secretary of State Hillary Clinton wrote in December 2009 in a cable released by Wikileaks that “Saudi Arabia remains a critical financial support base for al-Qa’ida, the Taliban, LeT [Lashkar-e-Taiba in Pakistan] and other terrorist groups.” She said that, in so far as Saudi Arabia did act against al-Qa’ida, it was as a domestic threat and not because of its activities abroad. This policy may now be changing with the dismissal of Prince Bandar as head of intelligence this year. But the change is very recent, still ambivalent and may be too late: it was only last week that a Saudi prince said he would no longer fund a satellite television station notorious for its anti-Shia bias based in Egypt.

The problem for the Saudis is that their attempts since Bandar lost his job to create an anti-Maliki and anti-Assad Sunni constituency which is simultaneously against al-Qa’ida and its clones have failed.

By seeking to weaken Maliki and Assad in the interest of a more moderate Sunni faction, Saudi Arabia and its allies are in practice playing into the hands of Isis which is swiftly gaining full control of the Sunni opposition in Syria and Iraq. In Mosul, as happened previously in its Syrian capital Raqqa, potential critics and opponents are disarmed, forced to swear allegiance to the new caliphate and killed if they resist.

The West may have to pay a price for its alliance with Saudi Arabia and the Gulf monarchies, which have always found Sunni jihadism more attractive than democracy. A striking example of double standards by the western powers was the Saudi-backed suppression of peaceful democratic protests by the Shia majority in Bahrain in March 2011. Some 1,500 Saudi troops were sent across the causeway to the island kingdom as the demonstrations were ended with great brutality and Shia mosques and shrines were destroyed.

An alibi used by the US and Britain is that the Sunni al-Khalifa royal family in Bahrain is pursuing dialogue and reform. But this excuse looked thin last week as Bahrain expelled a top US diplomat, the assistant secretary of state for human rights Tom Malinowksi, for meeting leaders of the main Shia opposition party al-Wifaq. Mr Malinowski tweeted that the Bahrain government’s action was “not about me but about undermining dialogue”.

Western powers and their regional allies have largely escaped criticism for their role in reigniting the war in Iraq. Publicly and privately, they have blamed the Iraqi Prime Minister Nouri al-Maliki for persecuting and marginalising the Sunni minority, so provoking them into supporting the Isis-led revolt. There is much truth in this, but it is by no means the whole story. Maliki did enough to enrage the Sunni, partly because he wanted to frighten Shia voters into supporting him in the 30 April election by claiming to be the Shia community’s protector against Sunni counter-revolution.

But for all his gargantuan mistakes, Maliki’s failings are not the reason why the Iraqi state is disintegrating. What destabilised Iraq from 2011 on was the revolt of the Sunni in Syria and the takeover of that revolt by jihadis, who were often sponsored by donors in Saudi Arabia, Qatar, Kuwait and United Arab Emirates. Again and again Iraqi politicians warned that by not seeking to close down the civil war in Syria, Western leaders were making it inevitable that the conflict in Iraq would restart. “I guess they just didn’t believe us and were fixated on getting rid of [President Bashar al-] Assad,” said an Iraqi leader in Baghdad last week.

Of course, US and British politicians and diplomats would argue that they were in no position to bring an end to the Syrian conflict. But this is misleading. By insisting that peace negotiations must be about the departure of Assad from power, something that was never going to happen since Assad held most of the cities in the country and his troops were advancing, the US and Britain made sure the war would continue.

The chief beneficiary is Isis which over the last two weeks has been mopping up the last opposition to its rule in eastern Syria. The Kurds in the north and the official al-Qa’ida representative, Jabhat al-Nusra, are faltering under the impact of Isis forces high in morale and using tanks and artillery captured from the Iraqi army. It is also, without the rest of the world taking notice, taking over many of the Syrian oil wells that it did not already control.

Saudi Arabia has created a Frankenstein’s monster over which it is rapidly losing control. The same is true of its allies such as Turkey which has been a vital back-base for Isis and Jabhat al-Nusra by keeping the 510-mile-long Turkish-Syrian border open. As Kurdish-held border crossings fall to Isis, Turkey will find it has a new neighbour of extraordinary violence, and one deeply ungrateful for past favours from the Turkish intelligence service.

As for Saudi Arabia, it may come to regret its support for the Sunni revolts in Syria and Iraq as jihadi social media begins to speak of the House of Saud as its next target. It is the unnamed head of Saudi General Intelligence quoted by Dearlove after 9/11 who is turning out to have analysed the potential threat to Saudi Arabia correctly and not Prince Bandar, which may explain why the latter was sacked earlier this year.

Nor is this the only point on which Prince Bandar was dangerously mistaken. The rise of Isis is bad news for the Shia of Iraq but it is worse news for the Sunni whose leadership has been ceded to a pathologically bloodthirsty and intolerant movement, a sort of Islamic Khmer Rouge, which has no aim but war without end.

The Sunni caliphate rules a large, impoverished and isolated area from which people are fleeing. Several million Sunni in and around Baghdad are vulnerable to attack and 255 Sunni prisoners have already been massacred. In the long term, Isis cannot win, but its mix of fanaticism and good organisation makes it difficult to dislodge.

“God help the Shia,” said Prince Bandar, but, partly thanks to him, the shattered Sunni communities of Iraq and Syria may need divine help even more than the Shia. More

Pakistan’s First Solar Project Is One Of The World’s Largest

Last week Pakistan’s Prime Minister Nawaz Sharif inaugurated Pakistan’s first solar power park, which will start generating 100 megawatts of energy by the end of the year and a total of 1,000 megawatts by 2016.

Solar Farm in Bahawalpur, Pakistan

The Quaid-e-Azam Solar Park project has 400,000 solar panels, with a total cost of around $131 million. When complete the plant will produce about 2.5 times the power coming from the 392 megawatt Ivanpah solar thermal plant in California’s Mojave Desert, making it one of the largest solar parks in the world.

“If you come here after one and a half years, you will see a river of solar panels, residential buildings and offices — it will be a new world,” said site engineer Muhammad Sajid, pointing towards the surrounding desert.

This is big news for a country suffering from chronic energy shortages that leave people without power for large chunks of the day on a regular basis. And then there’s the nearly half of the households that aren’t even connected to the grid,according to a World Bank study. When temperatures soar in the summer, electricity demand can fall short by around 4,000 megawatts.

At the inauguration, the prime minister said “the dearth of electricity has pushed the country backwards and its entire industry and agriculture sector have suffered immensely.”

Pakistan is one of the most vulnerable countries in the world to the impacts of climate change due to its location, population, and environmental degradation. A recent study in the journal Nature Climate Change found that people are already migrating out of the Pakistan for climate-related reasons such as flooding and heat stress, which have negative effects on agriculture and can prove very costly.

“We need energy badly and we need clean energy, this is a sustainable solution for years to come,” Imran Sikandar Baluch, head of the Bahawalpur district administration in Punjab where the plant is located, told the AFP. “Pakistan is a place where you have a lot of solar potential. In Bahawalpur, with very little rain and a lot of sunshine, it makes the project feasible and more economical.”

At a meeting shortly after the inauguration, Sharif approved expanding the project from from 10,000 acres to 15,000 acres and increasing the capacity from 1,000 megawatts to 1,500 megawatts. More

Thorium: the wonder fuel that wasn't

“Thorium-Fueled Automobile Engine Needs Refueling Once a Century,” reads the headline of an October 2013 story in an online trade publication. This fantastic promise is just one part of a modern boomlet in enthusiasm about the energy potential of thorium, a radioactive element that is far more abundant than uranium.

Thorium promoters consistently extol its supposed advantages over uranium. News outlets periodically foresee the possibility of "a cheaper, more efficient, and safer form of nuclear power that produces less nuclear waste than today's uranium-based technology."

Actually, though, the United States has tried to develop thorium as an energy source for some 50 years and is still struggling to deal with the legacy of those attempts. In addition to the billions of dollars it spent, mostly fruitlessly, to develop thorium fuels, the US government will have to spend billions more, at numerous federal nuclear sites, to deal with the wastes produced by those efforts. And America’s energy-from-thorium quest now faces an ignominious conclusion: The US Energy Department appears to have lost track of 96 kilograms of uranium 233, a fissile material made from thorium that can be fashioned into a bomb, and is battling the state of Nevada over the proposed dumping of nearly a ton of left-over fissile materials in a government landfill, in apparent violation of international standards.

Early thorium optimism. The energy potential of the element thorium was discovered in 1940 at the University of California at Berkeley, during the very early days of the US nuclear weapons program. Although thorium atoms do not split, researchers found that they will absorb neutrons when irradiated. After that a small fraction of the thorium then transmutes into a fissionable material—uranium 233—that does undergo fission and can therefore be used in a reactor or bomb.

By the early 1960’s, the US Atomic Energy Commission (AEC) had established a major thorium fuel research and development program, spurring utilities to build thorium-fueled reactors. Back then, the AEC was projecting that some 1,000 nuclear power reactors would dot the American landscape by the end of the 20th century, with a similar nuclear capacity abroad. As a result, the official reasoning held, world uranium supplies would be rapidly exhausted, and reactors that ran on the more-plentiful thorium would be needed.

With the strong endorsement of a congressionally created body, the Joint Committee on Atomic Energy, the United States began a major effort in the early 1960s to fund a two-track research and development effort for a new generation of reactors that would make any uranium shortage irrelevant by producing more fissile material fuel than they consumed.

The first track was development of plutonium-fueled “breeder” reactors, which held the promise of producing electricity and 30 percent more fuel than they consumed. This effort collapsed in the United States in the early 1980’s because of cost and proliferation concerns and technological problems. (The plutonium “fast” reactor program has been able to stay alive and still receives hefty sums as part of the Energy Department's nuclear research and development portfolio.)

The second track—now largely forgotten—was based on thorium-fueled reactors. This option was attractive because thorium is far more abundant than uranium and holds the potential for producing an even larger amount of uranium 233 in reactors designed specifically for that purpose. In pursuing this track, the government produced a large amount of uranium 233, mainly at weapons production reactors. Approximately two tons of uranium 233 was produced, at an estimated total cost of $5.5 to $11 billion (2012 dollars), including associated cleanup costs.

The federal government established research and development projects to demonstrate the viability of uranium 233 breeder reactors in Minnesota, Tennessee, and Pennsylvania. By 1977, however, the government abandoned pursuit of the thorium fuel cycle in favor of plutonium-fueled breeders, leading to dissent in the ranks of the AEC. Alvin Weinberg, the long-time director of the Oak Ridge National Laboratory, was, in large part, fired because of his support of thorium over plutonium fuel.

By the late 1980’s, after several failed attempts to use it commercially, the US nuclear power industry also walked away from thorium. The first commercial nuclear plant to use thorium was Indian Point Unit I, a pressurized water reactor near New York City that began operation in 1962. Attempts to recover uranium 233 from its irradiated thorium fuel were described, however, as a “financial disaster.” The last serious attempt to use thorium in a commercial reactor was at the Fort St. Vrain plant in Colorado, which closed in 1989 after 10 years and hundreds of equipment failures, leaks, and fuel failures. There were four failed commercial thorium ventures; prior agreement makes the US government responsible for their wastes.

Where is the missing uranium 233? As it turned out, of course, the Atomic Energy Commission’s prediction of future nuclear capacity was off by an order of magnitude—the US nuclear fleet topped out at about 100, rather than 1,000 reactors—and the predicted uranium shortage never occurred. America’s experience with thorium fuels faded from public memory until 1996. Then, an Energy Department safety investigation found a national repository for uranium 233 in a building constructed in 1943 at the Oak Ridge National Laboratory. The repository was in dreadful condition; investigators reported an environmental release from a large fraction of the 1,100 containers “could be expected to occur within the next five years in that some of the packages are approaching 30 years of age and have not been regularly inspected.” The Energy Department later concluded that the building had “deteriorated beyond cost-effective repair. Significant annual costs would be incurred to satisfy current DOE storage standards, and to provide continued protection against potential nuclear criticality accidents or theft of the material.” More

Japan's 25-year plan to have space solar power

Solar energy experts have long known that the best place to collect the sun's rays is in space. A solar farm in orbit could collect energy all the time, whereas ground-based arrays sit idle during the night.

And huge chunks of real estate are easier to come by in space, where solar collectors can be as enormous as they need to be. But the problems with turning solar energy in space into useable energy on Earth have kept space solar stuck in the land of science fiction since the 1960s.

Yet Japan's version of NASA, the Japan Aerospace Exploration Agency, is optimistic. JAXA recently unveiled a technology roadmap that says it can make solar arrays in orbit a reality by the 2030s, and that plant could supply 1 gigawatt of energy, the equivalent of one of the country's nuclear plants. Susumu Sasaki reports for IEEE Spectrum.

Microwaves are key to JAXA's plans. Some space solar concepts have proposed using lasers to beam the energy in orbit down to collectors on the surface, but the water molecules in the clouds can scatter laser light. That means you'd lose some of the energy on anything less than a perfectly clear day. Microwaves don't have that problem. So JAXA has designed multiple concepts in which the DC (direct current) power generated in orbit would be transformed into microwaves and then beamed to Earth's surface, where a farm of antennas would collect the microwaves and transform them back into DC electricity. JAXA says it can now perform these transformations with at least 80 percent efficiency on each end.

Another major hurdle for space solar is keeping the collectors pointed at the sun at all times so they can collect energy continuously. JAXA released one design that features a square panel measuring 2 kilometers (1.2 miles) on each side. But the panel's orientation is fixed, meaning the amount of energy it can produce varies. Another JAXA design solves this problem by incorporating two enormous mirrors that reflect sunlight onto photovoltaic panels positioned between them.

More hurdles: If a space solar array had to burn fuel to adjust its position, for example, that would add millions of dollars to the cost. So Japan is trying to design its components in such a way that they naturally counterbalance Earth's gravity and stay in position without adjustment. In the case of the two-mirror design, all those pieces would need to fly in careful, precise formation, something that has not been tried on so grand a scale.

In the transmission phase, more than a billion tiny antennas affixed to moveable panels would be required to receive the microwave energy coming from space. Those panels must constantly adjust their orientation to maximize how much energy they receive. JAXA plans to help them by sending a pilot signal from the ground to the satellite that would tell the satellite how to adjust the beam.

Despite these and more challenges, JAXA has rolled out an ambitious timeline: It plans to unveil a ground-based demonstration this year, then reveal progressively larger experimental satellites in 2017, 2021, and 2024. The major goal would come to fruition in the following decade: A 1-GW power station in 2031, and then one power station launched per year by the late 2030s.

Within a quarter-century, then, perhaps Japan's energy will come not from nuclear plants -- which are vulnerable to earthquakes, tsunamis, and planetary outbursts -- but from solar arrays that aren't even on the planet. More

Food shortages could be most critical world issue by mid-century

The world is less than 40 years away from a food shortage that will have serious implications for people and governments, according to a top scientist at the U.S. Agency for International Development.

Dr. Fred Davies

"For the first time in human history, food production will be limited on a global scale by the availability of land, water and energy," said Dr. Fred Davies, senior science advisor for the agency's bureau of food security. "Food issues could become as politically destabilizing by 2050 as energy issues are today."

Davies, who also is a Texas A&M AgriLife Regents Professor of Horticultural Sciences, addressed the North American Agricultural Journalists meeting in Washington, D.C. on the "monumental challenge of feeding the world."

He said the world population will increase 30 percent to 9 billion people by mid-century. That would call for a 70 percent increase in food to meet demand.

"But resource limitations will constrain global food systems," Davies added. "The increases currently projected for crop production from biotechnology, genetics, agronomics and horticulture will not be sufficient to meet food demand." Davies said the ability to discover ways to keep pace with food demand have been curtailed by cutbacks in spending on research.

"The U.S. agricultural productivity has averaged less than 1.2 percent per year between 1990 and 2007," he said. "More efficient technologies and crops will need to be developed—and equally important, better ways for applying these technologies locally for farmers—to address this challenge." Davies said when new technologies are developed, they often do not reach the small-scale farmer worldwide.

"A greater emphasis is needed in high-value horticultural crops," he said. "Those create jobs and economic opportunities for rural communities and enable more profitable, intense farming." Horticultural crops, Davies noted, are 50 percent of the farm-gate value of all crops produced in the U.S.

He also made the connection between the consumption of fruits and vegetables and chronic disease prevention and pointed to research centers in the U.S. that are making links between farmers, biologists and chemists, grocers, health care practitioners and consumers. That connection, he suggested, also will be vital in the push to grow enough food to feed people in coming years.

"Agricultural productivity, food security, food safety, the environment, health, nutrition and obesity—they are all interconnected," Davies said. One in eight people worldwide, he added, already suffers from chronic undernourishment, and 75 percent of the world's chronically poor are in the mid-income nations such as China, India, Brazil and the Philippines.

"The perfect storm for horticulture and agriculture is also an opportunity," Davies said. "Consumer trends such as views on quality, nutrition, production origin and safety impact what foods we consume. Also, urban agriculture favors horticulture." For example, he said, the fastest growing segment of new farmers in California, are female, non-Anglos who are "intensively growing horticultural crops on small acreages," he said. More

Quenching Kenya: Can New Water Discoveries Save East Africa?

Water scarcity is becoming the defining international crisis of the twenty-first century. Water conflicts rage across the world as communities struggle to secure a clean, reliable supply.

One of the world’s most water-stressed regions is East Africa. Overexploitation of water resources there has been compounded by declining snowpacks on Mount Kilimanjaro and Mount Kenya, which have shrunk since the late 1980s due to global warming. Meanwhile, Lake Turkana -- the world’s largest perennial desert lake -- has largely disappeared from Ethiopian territory, retreating south into Kenya.

In this light, the discovery of two significant aquifers in mostly arid Kenya by a Japanese-financed UNESCO project has been hailed as a potential game changer. The first, the Lotikipi Basin Aquifer, is situated just west of Lake Turkana. The second, the smaller Lodwar Basin Aquifer, is near Lodwar, the capital of Turkana county. The aquifers were discovered by a French firm, Radar Technologies International (RTI), using a space-based exploration technology called WATEX that was originally designed to reveal mineral deposits. The company blended satellite and radar imagery with geographical surveys and seismic data to detect moisture. Subsequent drilling by UNESCO confirmed the presence of aquifers. Three other suspected aquifers in the region have yet to be verified through drilling.

For parched and economically backward Turkana, more than one-third of whose residents are malnourished, the discovery of major groundwater reserves is a godsend. Not only will the reserves provide lifesaving water, they will also spur the development of agricultural and hydrocarbon sectors and improve the lives of the impoverished residents in this conflict-ridden region, which extends from Kenya into the borderlands of Ethiopia and South Sudan.
