The end of the Middle East

14 03 2017

I have to say, I am seriously chuffed that Nafeez Ahmed is calling it, as I have been for years now…. In a lengthy but well worth reading article in the Middle East Eye, Nafeez explains the convoluted reasons why we have the current turmoil in Iraq, Yemen, and Syria. He doesn’t mention Egypt – yet – but to be fair, the article’s focus in on Mosul and the implications of the disaster unfolding there……

It never ceases to amaze me how Egypt has managed to stay off the news radar. Maybe the populace is too starved to revolt again….

After oil, rice and medicines, sugar has run out in Egypt, as the country has announced a devaluation of 48% of its currency. In Egypt, about 68 million of the total 92 million people receive food subsidized by the State through small consumer stores run by the Ministry of supply and internal trade. After shortages of oil, rice and milk, and even medicines, now sugar scarcity has hit the country. Nearly three quarters of the population completely rely on the government stores for their basic needs.

Egypt produces 2 million tons of sugar a year but has to import 3 million to face domestic demand. However imports have become too expensive.  The country is expected to receive a loan of 12 billion dollars (11 billion euros) from the International monetary Fund (IMF) to tackle its food scarcity. The price for sugar in supermarkets and black markets are skyrocketing as well, with a kilogram costing around 15 pounds. If available, one could get sugar from subsidized government stores for 0.50 euros per kilo.

Nafeez goes into great and interesting detail re the dismaying shenanigans going on in nafeezIraq and Syria at the moment. I’ll leave it to you to go through what he wrote on the Middle East Eye site on those issues, but what struck me as relevant to what this blog is about is how well they correlate with my own thoughts here…..:

Among my findings is that IS was born in the crucible of a long-term process of ecological crisis. Iraq and Syria are both experiencing worsening water scarcity. A string of scientific studies has shown that a decade-long drought cycle in Syria, dramatically intensified by climate change, caused hundreds and thousands of mostly Sunni farmers in the south to lose their livelihoods as crops failed. They moved into the coastal cities, and the capital, dominated by Assad’s Alawite clan. 

Meanwhile, Syrian state revenues were in terminal decline because the country’s conventional oil production peaked in 1996. Net oil exports gradually declined, and with them so did the clout of the Syrian treasury. In the years before the 2011 uprising, Assad slashed domestic subsidies for food and fuel.

While Iraqi oil production has much better prospects, since 2001 production levels have consistently remained well below even the lower-range projections of the industry, mostly because of geopolitical and economic complications. This weakened economic growth, and consequently, weakened the state’s capacity to meet the needs of ordinary Iraqis.

Drought conditions in both Iraq and Syria became entrenched, exacerbating agricultural failures and eroding the living standards of farmers. Sectarian tensions simmered. Globally, a series of climate disasters in major food basket regions drove global price spikes. The combination made life economically intolerable for large swathes of the Iraqi and Syrian populations.

Outside powers – the US, Russia, the Gulf states, Turkey and Iran – all saw the escalating Syrian crisis as a potential opportunity for themselves. As the ensuing Syrian uprising erupted into a full-blown clash between the Assad regime and the people, the interference of these powers radicalised the conflict, hijacked Sunni and Shia groups on the ground, and accelerated the de-facto collapse of Syria as we once knew it.  


Meanwhile, across the porous border in Iraq, drought conditions were also worsening. As I write in Failing States, Collapsing Systems, there has been a surprising correlation between the rapid territorial expansion of IS, and the exacerbation of local drought conditions. And these conditions of deepening water scarcity are projected to intensify in coming years and decades.

The discernable pattern here forms the basis of my model: biophysical processes generate interconnected environmental, energy, economic and food crises – what I call earth system disruption (ESD). ESD, in turn, undermines the capacity of regional states like Iraq and Syria to deliver basic goods and services to their populations. I call this human system destabilisation (HSD).

As states like Iraq and Syria begin to fail as HSD accelerates, those responding – whether they be the Iraqi and Syrian governments, outside powers, militant groups or civil society actors – don’t understand that the breakdowns happening at the levels of state and infrastructure are being driven by deeper systemic ESD processes. Instead, the focus is always on the symptom: and therefore the reaction almost always fails entirely to even begin to address earth system sisruption.

So Bashar al-Assad, rather than recognising the uprising against his regime as a signifier of a deeper systemic shift – symptomatic of a point-of-no-return driven by bigger environmental and energy crises – chose to crackdown on his narrow conception of the problem: angry people.

Even more importantly, Nafeez also agrees with my predictions regarding Saudi Arabia…

The Gulf states are next in line. Collectively, the major oil producers might have far less oil than they claim on their books. Oil analysts at Lux Research estimate that OPEC oil reserves may have been overstated by as much as 70 percent. The upshot is that major producers like Saudi Arabia could begin facing serious challenges in sustaining the high levels of production they are used to within the next decade.

Another clear example of exaggeration is in natural gas reserves. Griffiths argues that “resource abundance is not equivalent to an abundance of exploitable energy”.

While the region holds substantial amounts of natural gas, underinvestment due to subsidies, unattractive investment terms, and “challenging extraction conditions” have meant that Middle East producers are “not only unable to monetise their reserves for export, but more fundamentally unable to utilise their reserves to meet domestic energy demands”. 

Starting to sound familiar..? We are doing the exact same thing here in Australia…. It’s becoming ever more clear that Limits to Growth equates to scraping the bottom of the barrel, and the scraping sounds are getting louder by the day.

And oil depletion is only one dimension of the ESD processes at stake. The other is the environmental consequence of exploiting oil.

Over the next three decades, even if climate change is stabilised at an average rise of 2 degrees Celsius, the Max Planck Institute forecasts that the Middle East and North Africa will still face prolonged heatwaves and dust storms that could render much of the region “uninhabitable”. These processes could destroy much of the region’s agricultural potential.

Nafeez finishes with a somewhat hopeful few paragraphs.

Broken models

While some of these climate processes are locked in, their impacts on human systems are not. The old order in the Middle East is, unmistakably, breaking down. It will never return.

But it is not – yet – too late for East and West to see what is actually happening and act now to transition into the inevitable future after fossil fuels.

The battle for Mosul cannot defeat the insurgency, because it is part of a process of human system destabilisation. That process offers no fundamental way of addressing the processes of earth system disruption chipping away at the ground beneath our feet.

The only way to respond meaningfully is to begin to see the crisis for what it is, to look beyond the dynamics of the symptoms of the crisis – the sectarianism, the insurgency, the fighting – and to address the deeper issues. That requires thinking about the world differently, reorienting our mental models of security and prosperity in a way that captures the way human societies are embedded in environmental systems – and responding accordingly.

At that point, perhaps, we might realise that we’re fighting the wrong war, and that as a result, no one is capable of winning.

The way the current crop of morons in charge is behaving, I feel far less hopeful that someone will see the light. There aren’t even worthwhile alternatives to vote for at the moment…  If anything, they are all getting worse at ‘leading the world’ (I of course use the term loosely..), not better. Nor is the media helping, focusing on politics rather than the biophysical issues discussed here.


It’s official……………

8 03 2017

I am now an old fart.

Yesterday, I turned 65 (will she still love me…?) and am now officially a pensioner. To celebrate, I did the unthinkable, flying over 2,500 km to join my family and friends in Queensland who all wanted to see me. Love miles George Monbiot calls them……. not only that, we also drove more than 300km in Glenda’s little car, though it would have only burned 15 litres of petrol doing so. I’m over feeling guilty over my travels now ; whatever I do (or don’t do) will not make one iota of difference to the outcomes of western civilisation…..

If ever I needed reminding of why I will never return to the big island, the weather while I was burning all those fossil fuels was downright awful. Maybe it’s because I am getting old, or maybe it’s due to climate change, but I could not remember the heat being as oppressive as it was……. as I type, in Geeveston, it’s 21 degrees (C of course…) and I have my shirt off……. after harvesting in the market garden, more later.

Everyone I spoke too was mumbling through the thick air about the oppressive heat, and the lack of rain…… worst summer in living memory, etc etc etc………… in the end, I spent most of the time eating, drinking, sweating (when not in airconditioning) or traveling by oil powered transport. Now I’m back, I have to wear off the pounds I put on in just three days!

Glenda and I made the time to see Bruce at Mt Glorious. Where too it was hot….. Mt Glorious? For Pete’s sake, it’s 600m above sea level..?

There’s never enough time to talk to Bruce. Like me, he is short of people he can have an actual conversation that makes sense with, and after just three hours, we had to go back down the mountain to the pea soup.

Bruce related a story to me that relates highly to an article I recently published about PV’s negative ERoEI. It goes something like this……:

His in-laws, who live off the grid near Stanthorpe in Queensland, had a pretty good 20 year old 24V battery bank charged with an array of 12V solar panels. It worked just fine, until the lady of the house decided to replace the fridge, and voila, the system could not cope. So she contacted the company who installed the original system to upgrade it. “But everything’s changed now” she was told…… you will have to replace the whole lot…. nonsense said Bruce (as I said when he was telling me what happened). 12V modules are a thing of the past now, unless you’re willing to pay for ‘camping’ versions of these things that cost ten times as much per Watt as the ‘conventional’ gear being screwed to everyone’s roofs these days…… talk about an expensive fridge.

The company involved could not be bothered to tinker with the system, they reckoned the batteries and associated inverter and charging gear were too old and not worth the effort. So off it all came, now replaced with the latest stuff, including the ridiculous use of a grid tied inverter needing to be hooked up to an ‘island’ bit of gear to make it work as a standalone inverter. And at 20 years old, all that stuff was right on the verge of paying itself off in energy return, but now it’s a pile of waste with a negative ERoEI. Bruce has the panels, but I suspect he doesn’t need them, though they could be good backup for his old system should anything go wrong with it……….

The other interesting thing that happened to me was on the flight up…… I just happened to sit next to this Canadian, who, after some banter, it was discovered knew all about peak oil and ‘the end of capitalism’. Maybe there are more and more people ‘getting it’ these days.


Steak from the neighbours, mashed potatoes with parsley and garlic from the garden, plus home grown beans – all washed down with home brewed cider made with apples from trees I can see from here…

Back to reality. I was a tad concerned about leaving my garden unattended, particularly not being watered in this warm weather, but I need not have worried, it seems to have thrived on neglect! This morning I harvested 7.3kg of tomatoes, 9.6kg of snow peas (!) and a 3kg zucchini that was as long as my arm…… a zuccini that big is not salable, so I chopped it up for the chooks. Waste nothing (unlike solar power companies).

I’m actually starting to feel like I’m living in abundance, at least for the time being. I ate a watermelon from the poly tunnel before leaving for Qld, and this morning I got stuck into a delicious rockmelon. I’ve been making blackberry jam, and there’s such a glut of berries now, I will be making more for the next couple of weeks…. and just before leaving, I bought half a pig from my neighbour, and is it soooo delicious……. Eat your heart out Queenslanders……

Feeding 9 billion

16 01 2017

I have just been tipped off to this fantastic Joel Salatin video…… I think it’s ironic that Eclipe, a fan of Polyface Farm, is in complete disagreement with Joel who is totally anti hi-tech farming. In fact, like me, Joel believes in walking away from the Matrix (exemplified in this video by McDonald’s), and he lets both barrels go at the establishment…..


The price of fuel..: what is going on..?

11 01 2017

Yesterday, I went to the big smoke for a medical appointment. I’m fine. But when I went to fill up to ensure I could make it home, I realised that the price of petrol had gone up by a whopping 20c/L in one hit. That’s a 14% increase……… in one day.Petrol price hike in Hobart

In the news, “Mr Moody (of the Royal Automobile Club of Tasmania) said prices were being driven up by increases in the global oil price, but he said the price should level out in Tasmania at about $1.40 a litre in about a month.”

Except that when I investigated this, the price of oil had not skyrocketed, it was still around $52 a barrel. Last time petrol was this expensive, oil was at $147 a barrel….. so what’s going on?

My take on this is that the oil companies must be finding it harder and harder to pay their interest bills. If they can’t make profits with oil, they’ll have to find them upstream at the pump.  Furthermore, maybe Peak Oil is on the cusp of getting really serious, and this might be the tip of the iceberg……. Nafeez Ahmed has just written the following article about how dire the oil situation is becoming…….

Brace for the oil, food and financial crash of 2018

80% of the world’s oil has peaked, and the resulting oil crunch will flatten the economy

New scientific research suggests that the world faces an imminent oil crunch, which will trigger another financial crisis.

A report by HSBC shows that contrary to industry mythology, even amidst the glut of unconventional oil and gas, the vast bulk of the world’s oil production has already peaked and is now in decline; while European government scientists show that the value of energy produced by oil has declined by half within just the first 15 years of the 21st century.

The upshot? Welcome to a new age of permanent economic recession driven by ongoing dependence on dirty, expensive, difficult oil… unless we choose a fundamentally different path.

Last September, a few outlets were reporting the counterintuitive findings of a new HSBC research report on global oil supply. Unfortunately, the true implications of the HSBC report were largely misunderstood.

The HSBC research note — prepared for clients of the global bank — found that contrary to concerns about too much oil supply and insufficient demand, the situation was opposite: global oil supply will in coming years be insufficient to sustain rising demand.screenshot

Yet the full, striking import of the report, concerning the world’s permanent entry into a new age of global oil decline, was never really explained. The report didn’t just go against the grain of the industry’s hype about ‘peak demand’: it vindicated what is routinely lambasted by the industry as a myth: peak oil — the concurrent peak and decline of global oil production.

The HSBC report you need to read, now

INSURGE intelligence obtained a copy of the report in December 2016, and for the first time we are exclusively publishing the entire report in the public interest.

Read and/or download the full HSBC report by clicking below:

HSBC peak oil report

The HSBC report has a helpful, ten-point summary of the key arguments the bank makes, and what is going on right now. These arguments are summarised below…:

  1. Oil’s oversupply problem, which has caused most of the trouble in the markets in recent years will end by 2017, and the market will return to balance.
  2. Spare capacity will have shrunk substantially by then “to just 1% of global supply/demand.” This HSBC argues, will make the market more susceptible to disruptions like those seen in Nigeria and Canada in 2016.
  3. Oil demand is still growing by ~1mbd every year, and no central scenarios that we recently assessed see oil demand peaking before 2040.”
  4. 81% of the production of liquid oil is already in decline.
  5. HSBC sees between 3 and 4.5 million barrels per day of supply disappearing once peak oil production is reached. “In our view a sensible range for average decline rate on post-peak production is 5-7%, equivalent to around 3-4.5mbd of lost production every year.”
  6. Based on a simple calculation, HSBC estimates that by 2040, the world will need to find around 40 million barrels of oil per day to keep up with growing demand from emerging economies. That is equivalent to over 4 times the current crude oil output of Saudi Arabia.
  7. “Small oilfields typically decline twice as fast as large fields, and the global supply mix relies increasingly on small fields: the typical new oilfield size has fallen from 500-1,000mb 40 years ago to only 75mb this decade.” — This will exacerbate the problem of declining oil fields, and the lack of supply.
  8. The amount of new oil discoveries being made is pretty small. HSBC notes that in 2015 the discovery rate for new wells was just 5%, a record low. The discoveries made are also fairly small in size.
  9. There is potential for growth in US shale oil, but it currently represents less than 5% of global supply, meaning that it will not be able, single-handedly at least, to address the tumbling global supply HSBC expects.
  10. “Step-change improvements in production and drilling efficiency in response to the downturn have masked underlying decline rates at many companies, but the degree to which they can continue to do so is becoming much more limited.” Essentially HSBC argues that companies aren’t improving their efficiency at a quick enough rate, meaning that supply declines will hit them even harder.

Here is the chart showing the decline in production post-peak:

Oil peak production

As usual, the mainstream media is spruiking loads of rubbish, probably trying to not scare the children…… unless you peek elsewhere like this blog, or follow other bloggers who keep abreast of the truth, you could be forgiven for thinking America will be great again…. or some other such rubbish.

Under the current supply glut driven by rising unconventional production, falling oil prices have damaged industry profitability and led to dramatic cut backs in new investments in production. This, HSBC says, will exacerbate the likelihood of a global oil supply crunch from 2018 onwards.
So how do you improve profitability? You put the price of fuel up. Given that petrol is the single biggest purchase made by households on a weekly basis, the lift in petrol prices may lead to less household activity — a potential concern for retailers and the economy generally. High fuel prices combined with large debts is what broke the camel’s back in 2008, causing the GFC. Things are not only not different today, debt levels are even higher….. how long before GFC MkII kicks off is anyone’s guess, but it can’t be too far away now….

The Trouble with Permaculture

4 10 2016

With the recent passing of Bill Mollison, much has been published on the interweb about Permaculture; While Glenda was here for nine days, I didn’t spend much time at this laptop, preferring to help her set her own stamp on the Fanny Farm and using her very able gardening skills to get stuck into some planting…. and fixing the goose tractor in readiness for the acquisition of more birds, but there will be time for that some place else on this site.

Having published Samuel Alexander’s epitaph for Bill Mollison by merely copying and pasting the Conversation article, I didn’t bother following the links therein; luckily, Greg Bell did, and posted a couple in a comment he left here, many thanks Greg…. as he says in his comment, “Those two “here” links to critiques of permaculture are the two most important things I’ve read all year (and they, in turn, link to even more)……

The first link is to and bears the same title as this entry. Fascinating reading indeed, as are the comments below it.

“But Can’t Technical Advance Solve the Problems?”

16 07 2016

More from Ted Trainer…..


Ted Trainer

Ted Trainer.


The “limits to growth” analysis argues that the pursuit of affluent lifestyles and economic growth are the basic causes of the many alarming global problems we are running into.  We have environmental destruction, resource depletion, an impoverished Third World, problems of armed conflict and deteriorating cohesion and quality of life in even the richest countries…essentially because the levels of producing and consuming going on are far too high.  There is no possibility of these levels being maintained, let alone spread to all the world’s people. We must shift to far lower levels of consumption in rich countries. (For the detail see Trainer, 2011.)

The counter argument most commonly raised against the limits case is that the development of better technology will solve the problems, an enable us to go on living affluently in growth economies.  Almost everyone seems to hold this belief. It has recently been reasserted as “Ecomodernism.” (For the main statements see Asaef-Adjaye, 2016, and  Blomqvist, Nordhaus Shellenbeger, 2015. For a detailed critique see Trainer 2016a.)

It is not surprising that this claim is regarded as plausible, because technology does constantly achieve miraculous breakthroughs, and publicity is frequently given to schemes that are claimed could be developed to solve this or that problem.  However there is a weighty case that technical advance will not be able to solve the major global problems we face.

The Simpler Way view is that technical advances cannot solve the big global problems and therefore we must change to lifestyles and social systems which do not generate those problems.  This could easily be done if we wanted to do it, and it would actually enable a much higher quality of life than most of us have now in consumer society.  But it would involve abandoning the quest for affluent lifestyles and limitless economic growth…so it is not at all likely that this path will be taken.

The problems are already far too big for technical advance alone to solve.

Most people have little idea how serious the main problems are, or how far beyond sustainable levels we are. Here are some indicators of how far we have exceeded the limits to growth.

  • The 2007 IPCC Report said that if greenhouse gas emissions are to be kept to a “safe” level they must be cut by 50-80% by 2050, and more after that. The 50% figure would mean that the average American or Australian would have to go down to under 5% of their present per capita emission rate. Some argue that all emissions should cease well before 2030. (Anderson and Bows, 2009, Hansen, 2008, Spratt, 2014.
  • By 2050 the amount of productive land on the planet per capita will be 0.8 ha (assuming we will stop damaging and losing land.)  The present amount required to give each Australian their lifestyle is 8 ha.  This means we are 10 times over a sustainable amount, and there is not the slightest possibility of all the world’s people ever rising to anywhere near our level.
  • Australians use about 280 GJ of energy per capita p.a.  Are we heading for 500 GJ/person/y by 2050?  If all the world’s expected 9.7 billion people were to live as we live world energy supply would have to be around 4,500 EJ/y…which is 9 times the present world energy production and consumption.
  • Almost all resources are scarce and dwindling. Ore grades are falling, and there have been food and water riots. Fisheries and tropical forests are in serious decline. Yet only about one-fifth of the world’s people are using most of these; what happens when the rest rise to our levels?
  • Many of the world’s ecosystems are in alarmingly rapid decline.  This is essentially because humans are taking so much of the planet’s area,  and 40% of the biological productivity of the lands.  We are causing a holocaust of biodiversity die-off mainly because we are taking the habitats other species need.  Of about 8 billion ha of productive land we have taken 1.4 billion ha for cropland, and about 3.5 billion ha for grazing.  We are depleting most of the fisheries.  The number of big fish in the oceans is down to 10% of what it was. We are destroying around 15 million ha of tropical forest every year.  And if all 9 billion people expected are going to live as we do now, resource demands would be about 10 times as great as they are now.  There are many other environmental impacts that are either past the limits biologists think are tolerable, or approaching them, including the rate of nitrogen release, ozone destruction, chemical poisoning of the earth and atmospheric aerosol loads. (Rockstrom, 2009.)
  • The World Wildlife Fund estimates that we are now using up resources at a rate that it would take 1.5 planet earths to provide sustainably. (WWF, 2014.) If 9.7 billion are to live as we expect to in 2050 we will need more than 20 planet earths to harvest from.

These are some of the many ways in which we have already greatly exceeded the planet’s capacity to meet human demands, and they define the task the tech-fix believer is faced with.  So ask the tech-fix optimist, “If technology is going to solve our problems, when is it going to start?  Just about all of them seem to be getting worse at present.”

Now add the absurdity of economic growth.

These and many other facts and figures only indicate the magnitude of the present problems caused by over-production and over-consumption.  To this alarming situation we must now add the fact that our society is committed to rapid and limitless increases in “living standards” and GDP; i.e., economic growth is the supreme goal.

If we Australians have 3% p.a. economic growth to 2050, and by then all 9.7 billion people will have come up to the “living standards” we will have by then, the total amount of economic production in the world each year will be about 20 times as great as it is now.  The present amount of production and resource use is grossly unsustainable, yet we are committed to economic system which will see these rates multiplied 20 times by 2050.

And note that most of the resources and ecosystems we draw on to provide consumer lifestyles are deteriorating. The WWF’s Footprint index tells us that at present we would need 1.5 planet Earth’s to provide the resources we use sustainably. So the Tech-fix advocate’s task is to explain how we might cope with a resource demand that is 20×1.5 = 30 times a currently sustainable level by 2050…and twice as much by 2073 given 3% p.a. growth.

Huge figures such as these define the magnitude of the problem for technical-fix believers.  We are far beyond sustainable levels of production and consumption; our society is grossly unsustainable, yet its fundamental determination is to increase present levels without limit.  If technical advance is going to solve the problems caused by all that producing and consuming it must cut resource use and impacts by a huge multiple…and keep it down there despite endless growth.  Now ask the tech-fix believer what precisely he thinks will enable this.

Faith-based tech-fix optimism.

At this point we usually find that the belief in tech–fix is nothing but a faith, and one that has almost no supporting evidence.   Because technology has achieved many wonders it is assumed that it will come up with the required solutions, somehow.  This is as rational as someone saying, “I have a very serious lung disease, but I still smoke five packs of cigarettes a day, because technical advance could come up with a cure for my disease.”  This argument is perfectly true… and perfectly idiotic.  If you are on a path that is clearly leading to disaster the sensible thing is to get off it.  If technology does come up with solutions then it might make sense to get back on that path again.

The tech-fix optimist should be challenged to show in detail what are the grounds for us accepting that solutions will be found, to each and every one of the big problems we face.  What precisely might solve the biodiversity loss problem, the water shortage, the scarcity of phosphorus, the collapse of fish stocks, etc., and how likely are these possible beak-throughs?   Does it not make better sense to change from the lifestyles and systems that are causing these problems, at least until we can see that we can solve the resulting problems?

It should be stressed that the argument here is not to deny or undervalue the many astounding advances being made all the time in fields like medicine, astronomy, genetics, sub-atomic physics and IT, or to imply that these will not continue. The point is that technical advance is very unlikely to come up with ways that solve the resource and environmental problems being generated by affluent lifestyles.  The argument is that when the magnitude of the task (above) and the evidence on the significance of technical advance for resource and ecological problems is considered (below), tech-fix faith is seen to be extremely unwarranted … and the solutions have to be sought in terms of shifting to a Simpler Way of some kind.

Amory Lovins and Factor 4 or 5 reductions.

For decades Amory Lovins has been possibly the best known of several people who argue that technical advances could cut resource use per unit of GDP considerably.  He says we could in effect have 4 times the output with the same impact.  (Von Weizacher and Lovins, 1997).  But the above numbers make it clear that this is far from sufficient.  If by 2050 we should cut ecological impact and resource use in half (remember footprint and other indices show this is far from enough), but we also increase economic output by 20, then we’d need a factor 40 reduction, not Factor 4…and resource demand would be twice as high in another 23 years if 3% growth continued.

The factors limiting what technical advance can do.

It is important to keep in mind that there are several factors which typically determine the gains a technical advance actually enables are well below those that seem possible at first.  Engineers and economists make the following distinctions.

  • “Technical potential.”  This is what the technology could achieve if fully applied with no regard to cost or other problems.
  • Economic (or ecological) potential”.  This is usually much less than the technical potential because to achieve all the gains that are technically possible would cost too much.  For instance it is technically possible for passenger flights to be faster than sound, but it is far too costly.  It would be technically possible to recycle all lead used, but it would be much too costly in dollars and convenience to do so. Some estimate that it would be technically possible to harvest 1,400 million ha for biomass energy per year, but when ecologically sensitive regions are taken out some conclude that the yield could only be 250 million ha or less. (World Wildlife Fund, 2010, p. 181.)  The WWF study quotes Smeets and Faiij (2007) as finding that it would be technically possible for the world’s forests to produce another 64 EJ/y of biomass energy p.a., but Field, Campbelo and Lobell (2007) conclude that only 27 EJ/y can be obtained, under 2 per cent of the Smeets and Faiij figure.
  • What are the net gains?  Enthusiastic claims about a technical advance typically focus on the gains and not the costs which should be subtracted to give a net value.  For instance the energy needed to keep buildings warm can be reduced markedly, but it costs a considerable amount of energy to do this, in the electricity needed to run the air-conditioning and heat pumps, and in the energy embodied in the insulation and triple glazing.

The WWF Energy Report (2010) claims that big savings can be made in building heating and cooling, but their Figs. 3 – 11 and 3 – 12 show that although their measures would reduce heat used in buildings by 90%, electricity used would increase c. 50% (and there is no reference to what the embodied energy cost of manufacturing the equipment and insulation might be.)  The graphs don’t seem to show any net reduction in building energy use.

The Green Revolution doubled food yields, but only by introducing crops that required high energy inputs in the form of expensive fertilizers, seeds and irrigation.  One result was that large numbers of very poor farmers went out of business because they couldn’t afford the inputs.

Similarly, it is possible to solve some water supply problems by desalination, but only by increasing the energy and greenhouse problems.

  • What is socially/politically possible?  Then there are limits set by what people will accept.  It would be technically possible for many people in Sydney to get to work by public transport, but large numbers would not give up the convenience of their cars even if they saved money doing so.  The energy efficiency of American cars is much lower than what is technically possible, and in fact lower than it was decades ago … because many people want energy-intensive vehicles.  Australians are now building the biggest and most energy wasteful houses in the world.  A beautiful, tiny, sufficient mud brick house could be built for less than $10,000…but most people would not want one.  These examples make it clear that the problems of over-consumption in many realms are mainly social rather than technical, and that they can’t be solved by technical advance.  The essential tech-fix issue is to do with whether or not the problems can be solved by technical advances which allow us to go on living and consuming as we were before, or whether we must change to values and behaviour that don’t cause problems.
  • The Jevons or “rebound” effect.  Then there is the strong tendency for savings made possible by a technical advance to be spent on consuming more of the thing saved or something else.  For instance if we found how to get twice the mileage per litre of petrol many would just drive a lot more, or spend the money saved on buying more of something else.  The Indians have recently developed a very cheap car, making it possible for many more low income people to drive, consume petrol and increase greenhouse gases.

So it is always important to recognise that an announced technical miracle breakthrough probably refers to its technical potential but the savings etc. that it is likely to enable in the real world will probably be well below this.

Some evidence on technical advance in the relevant fields.

Again the focus here is on fields which involve high resource or ecological impacts and demands, not on the many advances being made in fields like medicine or particle physics. It should not be assumed that in general rapid, large or continuous technical gains are being routinely made in the relevant fields, especially in crucial areas such as energy efficiency. Ayres (2009) notes that for many decades there have been plateaus for the efficiency of production of electricity and fuels, electric motors, ammonia and iron and steel production.  The efficiency of electrical devices in general has actually changed little in a century (Ayres, 2009, Figs. 4.1 and 4.19, p. 127.)  “…the energy efficiency of transportation probably peaked around 1960”.  (p. 126), probably due to increased use of accessories.  Ayres’ Fig. 4.21a shows no increase in the overall energy efficiency of the US economy since 1960. (p. 128.)  He notes that reports tend to publicise particular spectacular technical advances and this can be misleading regarding long term average trends across whole industries or economies.

We tend not to hear about areas where technology is not solving problems, or appears to have been completely defeated.  Not long ago everyone looked forward to super-sonic mass passenger flight, but with the demise of Concorde this goal has been abandoned.  It would be too difficult and costly, even without an energy crunch coming up.  Sydney’s transport problems cannot be solved by more public transport; more rail and bus would improve things, but not much because the sprawling city has been build for the car on 70 years of cheap oil.  Yes you could solve all its problems with buses and trains, but only at an infinite cost.   The Murray-Darling river can only be saved by drastic reduction in the amount of water being taken out of it.  The biodiversity holocaust taking place could only be avoided if humans stopped taking so much of nature, and returned large areas of farmland and pasture to natural habitat. (For an extremely pessimistic analysis of what future technology might achieve, see Smith and Positrano, 2010.)

Most indices of technical progress, efficiency and productivity show long term tapering towards ceilings.  “But what about Moore’s law, where by computer chip power has followed a steep upward curve?”  Yes in some realms this happens, for a time, but the trend in IT is highly atypical.  (By the way, the advent of computers has not made much difference at all to the productivity of the economy; indeed in recent decades productivity growth indices for national economies have fallen.  This is identified as “The Productivity Paradox.”)

There are two important areas where recent trends seem to run counter to this argument; the remarkable fall in the costs of PV panels and the advent of new batteries. However the significance of these is uncertain. The PV cost is largely due to latge subsidies, very cheap labour, and the general failure of the Chinese economy to pay ecological costs of production. (On the enormous difference the last factor makes see Smith, 2016.)  Thus the real cost, and that which we will have to pay in future is likely to be much higher.  (… the EIA thinks costs will probably rise before long.), The significance of the new battery technology is clouded by the fact that costs would have to fall by perhaps two-thirds before they could be used for grid storage without greatly increasing the cost of power, and it is not likely that there is enough Lithium to enable grid level storage of renewable energy.

The crucial “decoupling” issue.

The fundamentally important element in the tech-fix or ecomodernist position is the belief/claim that resource demand and ecological impact can be “decoupled” from economic growth, that is, that new ways will enable the economy to keep growing and “living standards”, incomes and consumption to continue rising without increasing resource use or environmental damage (or while keeping these down to sustainable levels.) The following passages deal with considerable evidence on decoupling and show this belief to be extremely implausible, to put it mildly.

What about the falling “energy intensity” of the economy?”

The fact that the “energy intensity” of rich world economies, i.e., ratio of GDP to gross energy used within the country has declined is often seen as evidence of decoupling but this is misleading. It does not take into account the large amounts of energy embodied in imports, i.e., energy use we benefit from but does not show up in our national accounts.  (below.) Possibly more important is the long term process of “fuel switching”, i.e., moving to forms of energy which are of “higher quality” and enable more work per unit. For instance a unit of energy in the form of gas enables more value to be created than a unit in the form of coal, because gas is more easily transported, switched on and off, or converted from one function to another, etc. (Stern and Cleveland, 2004, p. 33, Cleveland et al., 1984, Kaufmann, 2004,  Office of Technology Assessments, 1990, Berndt, 1990, Schurr and Netschurt, 1960.)

What about productivity increases?

It is commonly thought that the power of technology is evident in the constantly improving productivity of the economy.  Again this is misleading, firstly because productivity gains have been low and decreasing in recent decades and this is a constant concern and puzzle among economists and politicians. Even the advent of computerisation has had a surprisingly small effect, a phenomenon now labelled the “Productivity Paradox.”

The overlooked role of energy in productivity growth and decoupling.

Most of the productivity growth that  has taken place now seems to have been due not to technical advance but to increased use of energy. Previous analyses have not realized this but have analysed only in terms of labour and capital input “factors of production”. Agriculture is a realm where technical advance has been predominantly a matter of increased energy use. Over the last half century productivity measured in terms of yields per ha or per worker have risen dramatically, but these have been mostly due to even greater increases in the amount of energy being poured into agriculture, on the farm, in the production of machinery, in the transport, pesticide, fertilizer, irrigation, packaging and marketing sectors, and in getting the food from the supermarket to the front door, and then dealing with the waste food and packaging. Less than 2% of the US workforce is now on farms, but agriculture accounts for around 17% of all energy used (not including several of the factors listed above.) Similarly the “Green Revolution” has depended largely on ways that involve greater energy use.

Ayres, et al., (2013), Ayres, Ayres and Warr (2002) and Ayres and Vouroudis (2013) are among those beginning to stress the significance of energy in productivity, and pointing to the likelihood of increased energy problems in future and thus declining productivity. Murillo-Zamorano, (2005, p. 72) says “…our results show a clear relationship between energy consumption and productivity growth.” Berndt (1990) finds that technical advance accounts for only half the efficiency gains in US electricity generation. These findings caution against undue optimism regarding what pure technical advance can achieve independently from increased energy inputs; in general its significance for productivity gains appears not to have been as great as has been commonly assumed.

The productivity trend associated with this centrally important factor, energy, is itself in serious decline, evident in long term data on EROI ratios. Several decades ago the expenditure of the energy in one barrel of oil could produce 30 barrels of oil, but now the ratio is around 18 and falling. The ratio of petroleum energy discovered to energy required has fallen from 1000/1 in 1919 to 5/1 in 2006. (Murphy, 2010.) Murphy and others suspect  that an industrialised society cannot be maintained on a general energy ratio under about 10. (Hall, Lambert and Balough, 2014.)

So when we examine the issue of productivity growth we find little or no support for the general tech-fix faith.  It is not the case that technical breakthroughs are constantly enabling significantly more to be produced per unit of inputs. The small improvements in productivity being made seem to be largely due to changes to more energy-intensive ways, and energy itself is exhibiting marked deterioration in productivity (ie, as evident in its EROI.) Some analysts (e.g., Ayres, 2009, Ayres et al., 2013) believe that any gains occurring now will probably disappear with coming rises in energy scarcity and cost.

Lets examine ewhere materials are used; not general GDP

Evidence on low past and present decoupling achievement.

The historical record suggests that at best rates of decoupling materials and energy use from GDP have been very low or less than zero; i.e., some important measures show materials or energy use to be increasing faster than GDP. It is important not to focus on national measures such as “Domestic Materials Consumption” as these do not take into account materials in imported goods.  For example the OECD (2015) claims that materials used within its countries has fallen 45% per dollar of GDP, but this figure does not take into account materials embodied in imported goods. When they are included rich countries typically show very low or worsening ratios. The commonly available global GDP (deflated) and energy use figures between 1980 and 2008 reveals only a 0.4% p.a. rise in GDP per unit of energy consumed.   Tverberg () reproduces the common plot for global energy use and GWP, showing an almost complete overlay; i.e., no tendency for energy use to fall away from GWP growth.

Weidmann et al. (2014) show that when materials embodied in imports are taken into account rich countries have not improved their resource productivity in recent years. They say “…for the past two decades global amounts of iron ore and bauxite extractions have risen faster than global GDP.” “… resource productivity…has fallen in developed nations.” “There has been no improvement whatsoever with respect to improving the economic efficiency of metal ore use.”

Giljum et al. (2014, p. 324) report only a 0.9% p.a. improvement in the dollar value extracted from the use of each unit of minerals between 1980 and 2009, and that over the 10 years before the GFC there was no improvement. “…not even a relative decoupling was achieved on the global level.” Their Fig. 2, shows that over the period 1980 to 2009 the rate at which the world decoupled materials use from GDP growth was only one third of that which would have achieved an “absolute” decoupling, i.e., growth of GDP without any increase in materials use. It must be stressed here that, as they point out, these findingss would have been worse had the production of much rich world consumption not been outsourced to the Third World (that is, had energy embodied in imports been included.)

Diederan’s account (2009) of the productivity of minerals discovery effort is even more pessimistic. Between 1980 and 2008 the annual major deposit discovery rate fell from 13 to less than 1, while discovery expenditure went from about $1.5 billion p.a. to $7 billion p.a., meaning the productivity expenditure fell by a factor in the vicinity of around 100, which is an annual decline of around 40% p.a. Recent petroleum figures are similar; in the last decade or so discovery expenditure more or less trebled but the discovery rate has not increased.

A recent paper in Nature by a group of 18 scientists at the high-prestige Australian CSIRO (Hatfield-Dodds et al., 2015) argued that decoupling could eliminate any need to worry about limits to growth at least to 2050. The article contained no support for the assumption that the required rate of decoupling was achievable and when it was sought (through personal communication) reference was made to the paper by Schandl et al. (2015.)  However that paper contained the following surprising statements, “ … there is a very high coupling of energy use to economic growth, meaning that an increase in GDP drives a proportional increase in energy use.”  (They say the EIA, 2012, agrees.) “Our results show that while relative decoupling can be achieved in some scenarios, none would lead to an absolute reduction in energy or materials footprint.” In all three of their scenarios “…energy use continues to be strongly coupled with economic activity…”

The Australian Bureau of Agricultural Economics (ABARE, 2008) reports that the energy efficiency of energy-intensive industries is likely to improve by only 0.5% p.a. in future, and of non-energy-intensive industries by 0.2% p.a. In other words it would take 140 years for the energy efficiency of the intensive industries to double the amount of value they derive from a unit of energy.

Alexander (2014) concludes his review of decoupling by saying, ”… decades of extraordinary technological development have resulted in increased, not reduced, environmental impacts.”  Smil (2014) concludes that even in the richest countries absolute dematerialization is not taking place. Alvarez found that for Europe, Spain and the US GDP increased 74% in 20 years, but materials use actually increased 85%. (Latouche, 2014.) Similar conclusions re stagnant or declining materials use productivity etc. are arrived at by Aadrianse, 1997, Dettrich et al., (2014), Schutz, Bringezu and Moll, (2004), Warr, (2004), Berndt, (undated), and Victor (2008, pp. 55-56).

A version of the decoupling thesis is the “Environmental Kuznets Curve”, i.e., the claim that as economic development takes place environmental impacts increase but then decrease. The evidence on this thesis indicates that it is not correct. Greenhouse gas emissions give us a glaring example. Alexander concludes his review, (2014),  “If the EKC hypothesis sounds too good to be true, that is because, on the whole, it is false.”

These sources and figures indicate the apparently total lack of support for the ecomodernists’ optimism. They are assuming that there can be massive absolute decoupling, i.e., that by 2050 energy, materials and ecological demand associated with $1 of GDP can be reduced by a factor of around 30. There appears to be noecomodernist literature that even attempts to provide good reason to think a general absolute decoupling is possible, let alone on the required scale. (I have made about five attempts to have such evidence sent to me from the leading ecomodernist authors, without receiving any.)

            The changing components of GDP.

There is another consideration that makes the situation much worse. Over recent decades there has been a marked increase in the proportion of rich nation GDP that is made up of “financial” services. These stand for “production” that takes the form of key strokes that move electrons around.  A great deal of it is wild speculation, making risky loans and making computer driven micro-second switches in “investments”. These operations deliver massive increases in income to banks and managers, commissions, loans, interest, consultancy fees.  These make a big contribution to GDP figures. In one recent year 40% of US corporate profits came from the finance sector. It could be argued that this domain should not be included in estimates of productivity because it misleadingly inflates the numerator in the output/labour ratio.

This means that the most significant measures will be to do with industries that use material and ecological inputs.  The crucial question is, in those industries that are causing the pressure on resources and ecosystems is significant decoupling taking place? However when output per worker in the production of “real” goods and services such as food and vehicles, or aged care is considered we do not seem to find reassuring evidence of decoupling.  Again agricultural industry provides some of the best examples. Over the last 50 years there has been a huge increase in energy used in fuel, pesticides, fertilizers, transport, packaging, marketing and waste treatment. Kowalski (2011) reports that between 1960 and 2010 world cereal production increased 250%, but nitrogen fertilizer use in cereal production increased 750%. Between 1997 and 2002 the US household use of energy on food increased 6 times as fast as use for all household purposes. (Canning et al., 2010.)

The enormous implications for energy demand.

The main ecomodernist texts make clear that if the technical advances envisaged could not take place unless there was extremely large scale increase in the amount of energy produced.  They look forward to shifting a large fraction of agriculture off land into intensive systems such as high rise greenhouses and acquaculture, massive use of desalination for water supply, processing lower grade ores, dealing with greatly increased amounts of industrial waste (especially mining waste), and constructing urban infrastructures for billions to live in as they propose shifting people from the land to allow more of it to be returned to nature.  They do not think renewable energy sources can provide these quantities of energy, so their proposals would have to involve very large numbers of fourth generation nuclear reactors (which run on plutonium). How large?

If 9 billion people were to live on the per capita amount of energy Americans now average, world energy consumption in 2050 would be around x5 (for the US to world average ratio) x10/7 (for population growth) times the present 550 EJ p.a., i.e., around 3,930 EJ. The nuclear generating capacity needed would be around 450 times as great as at present.

And the baseline is deteriorating…

The general “limits to growth” analysis of the global situation makes it clear that the baseline on which ecomodernist visions must build is not given by present conditions such as resource availability. As Steffen et al. (2015) and many others stress the baseline is one of not just deteriorating conditions, but accelerating deterioration.

It is as if the ecomodernists are claiming that their A380 can be got to climb at a 60 degree angle, which is far steeper than it has ever done before, but at present it is in an alarming and accelerating decline with just about all its systems in trouble and some apparently beyond repair. The problem is the wild party on board, passengers and crew dancing around a bonfire and throwing bottles at the instruments, getting more drunk by the minute. A few passengers are saying the party should stop, but no one is listening, not even the pilots. The ecomodernist’s problem is not just about producing far more metals, it is about producing far more as grades decline, it is not just about producing much more food, it is about producing much more despite the fact that problems to do with water availability, soils, the nitrogen cycle, acidification, and carbon loss are getting worse.  It can be argued that on many separate fronts halting the deteriorating trends is now unlikely to be achieved. Yet the ecomodernist wants us to believe that the curves can be made to cease falling and to rise dramatically, without abandoning the quests for affluence and growth which are responsible for their deterioration.  Stopping the party is not thought to warrant consideration.

This is not an argument against technology.

Research and development and improving things are obviously important and in The Simpler Way vision we would have more resources going into technical research than we have now despite a much lower GDP, because we would have phased out the enormous waste of resources that occurs in consumer-capitalist society.  But it is a mistake to think that the way to solve our problems is to develop better technology.  That will not solve the problems, because they are far too big, and they are being generated by trying to live in ways that generate impossible resource demands. The big global problems have been caused by our faulty social systems and values.  The solution is to develop ways and systems that don’t generate the problems, and this requires movement away from affluent, high energy, centralised, industrialised, globalised etc., systems and standards. Above all it requires a shift from obsession with getting rich, consuming and acquiring property. It requires a willing acceptance of frugality and sufficiency, of being content with what is good enough.

Hundreds of years ago we knew how to produce not just good enough but beautiful food, houses, cathedrals, clothes, concerts, works of art, villages and communities, using little more than hand tools and crafts.  Of course we should use modern technologies including computers (if we can keep the satellites up there) where these make sense.  But we don’t need much high-tech to design and enjoy high quality communities.

Some of our most serious problems are to do with social breakdown, depression, stress, and falling quality of life.  These problems will not be solved by better technology, because they derive from faulty social systems and values.  Technical advances often make these problems worse, e.g., by increasing the individual’s capacity to live independently of others and community, and by enabling machines to cause unemployment. Especially worrying is the fact that ecomodernist dreams would involve massive globally integrated professional and corporate run systems involving centralised control and global regulatory systems (e.g., to prevent proliferation of radioactive materials from all those reactors.  Firstly this is not a scenario that will have a place for billions of poor people.  It will enable a few super-smart techies, financiers and CEOs to thrive, making inequality far more savage, and it will set impossible problems for democracy because there will be abundant opportunities for those in the centre to sdrure their own interests, to be corrupt and secretive.

Food for thought…..

1 07 2016

I recently published an item about the jetstream crossing the equator. At the time, I said I didn’t know what to make of it, and now it turns out to be bogus…… so I’ve pulled it.

Two bloggers have made a stunning claim that has spread like wildfire on the Internet: They say the Northern Hemisphere jet stream, the high-altitude river of winds that separates cold air from warm air, has done something new and outrageous. They say it has crossed the equator, joining the jet stream in the Southern Hemisphere. One said this signifies that the jet stream is ‘wrecked‘, the other said it means we have a “global climate emergency.”

But these shrill claims have no validity — air flow between the hemispheres occurs routinely. The claims are unsupported and unscientific, and they demonstrate the danger of wild assertions made by non-experts reaching and misleading the masses.

Just goes to show, you cannot believe everything you read on the internet, and frankly, I’m relieved as someone who staunchly believes the only place to live is as far away from the Northern Hemisphere..!

Below is Mark Cochrane’s latest offering…..


Mark Cochrane

Having just come back from a new region of agricultural development in Brazil and seeing some new research just out on related issues in other regions I thought I´d illustrate some of the climate-related issues in our global food production that we are facing.

Here in Brazil, agricultural expansion has been a large part of the regional economy and is the only actual growth sector in a country mired in political chaos and economic contraction (link). That said, much like the search for new energy sources, new agricultural lands are cut from the landscape on increasingly marginal lands.

With the development of soybean cultivars that could survive short day lengths near the equator and expanding global markets, this crop first spread through the Brazilian Cerrado and then into the southern Amazon, converting native vegetation to agricultural lands and even pushing cattle operations out of the way as pasturelands were bought up. Corn, cotton, sorghum and coffee have also spread to lesser degrees. Soils, climate, pests and infrastructure (or lack thereof) have provided challenges all along the way.

Despite this, the industry has thrived and land prices have soared to the point that new frontiers have opened up including the so called Matopiba region, which is an acronym for an amorphous area at the junction of Maranhâo, Tocantins, Piaui, and Bahia states. The region was originally passed over because it was considered unprofitable to farm but high commodity prices, technological breakthroughs and cheap land prices have driven exponential growth of farming and whole cities to spring up in the last 15 years that are impressive, if tenuous.

Nobody mentions the soils because they are uniformly poor and acidic. Lime applications are needed to lock up the toxic aluminum and fertilizers are needed to get decent crop growth. The region is dry, and though irrigation has not always been needed, it has proven critical over the last five years of unprecedented drought. There were 10 good years of production but now many are losing money with drought stunted crops and low production. Planted crop varieties are GM variants of Bt cultivars. Trying to plant anything else has proven a monetary disaster. Despite this built in biological pesticide, repeated applications of chemical pesticides are necessary as well, with 10-15 applications per growing season common! One farmer needed 30 applications in a single six-month season. It is safe to say that the insects are building up resistance rapidly and the local aquifers will not be pure for long. Interestingly, water is less limiting than the cost of actually pumping it for irrigation purposes.Energy is expensive and unreliable.

I mention all of this because these sorts of regions and problems are inherent in all ´new´ lands being brought into production to try to feed our planet´s exploding population. These areas are incredibly vulnerable to changing climate, commodity prices, energy prices, pests and pathogens. It takes a lot of effort to bring them into production but they could dry up and blow away all too easily. Management of production in these sorts of areas is necessary and difficult to mitigate and adapt to climate changes.

New research  (Challinor et al. 2016) indicates that breeding, delivery and adoption of new climate appropriate variants of crops (maize in this case) may not be able to keep up with the changing conditions likely in the coming decades. Much like conversion to a new energy source can take decades to implement after development, planting new variants of a crop or more appropriate crops for a changing climate can take decades to permeate a region, especially in developing countries. The upshot being that productivity levels are likely to fall over time with changing climates.

On the front of dubious good news, a large ´water windfall´ has been discovered underneath California´s Central Valley. Up to three times as much water as was previously estimated may reside under this region which sounds like a great thing until you realize that much of this new water resource resides between 300 and 3,000 meters below the surface (Kang and Jackson 2016). These water reserves may not be economically accessible for irrigation purposes and are complicated by the numerous (35,000!) oil and gas wells that currently perforate it (link). Never mind the fact that the land itself has been sinking rapidly with groundwater pumping.

When you are contemplating the viability of pumping water from more than a mile beneath the surface in order to water your crops, it is clear that the battle to maintain production is being lost. If power cannot be generated extremely cheaply then this region, the most productive in the United States, will fall out of production in the not too distant future for anything but dryland agriculture.

The take home message here is that it will become increasingly difficult to maintain current agricultural production levels at a time when we need to dramatically increase them to feed rapidly growing human populations. There may never have been a better time to take up gardening to ensure a modicum of calories for your family…
