How sustainable is development?

The phrase "sustainable development" has become a sort of word-in-itself.  You can't talk about development without adding the word sustainable.

The trouble is that sustainabledevelopment is really undefined.  There have been noble attempts - everyone remembers the Brundtland story:
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Great stuff, but completely useless - you can't dig up something to keep your world going, because that means future generations won't be able to dig it up. The resources of the world are finite, right?

Recently I mulled over the paradox that we never seem to run out of non-renewable things like oil, but we are always running out of renewable things like rhinos and whales and fish and elephant.  There has, of course, been a thesis that we should already have run out of oil - it was called "peak oil" and a man called Hubbard who had worked for Shell developed the theory back in the 1960's. 

 However, in 1945 the world had 25 years of known oil; by 1970 we had used up all that oil, but by then had 30 years left. By 2000 we had used up all the 1970 oil, but by then had 40 years left.  Today we have used up 15 of the 40 years, but we have 55 years left.  What gives?

My resolution of the paradox was that, yes, the renewable resources are indeed finite, but the non-renewable stuff is not measured by the resource but by the reserves, and reserves are something quite different.  They depend on price and technology, and technology is the measure of human ingenuity, so the reserve is flexible and potentially expandable, whereas the poor old renewables have to fend for themselves.

In exploring this in a full-blown paper, I was led to separate sustainabledevelopment back into two words, and ask just what was "sustainable" and just what we meant by "development".  When I tried to publish the paper, one reviewer sniffily reported that I didn't understand sustainabledevelopment, which was rather unhelpful, and another made some useful comments about my economics, but complained I had "merely" used some widely available data, so could not recommend publication.  I am still trying to get the paper published, but recognize how truly politically correct sustainabledevelopment has become.

Of course, its political correctness flows from its being blessed by the United Nations. There are regular conferences on the topic.  One, back in 2000, set up six Millennium Development Goals to be achieved by 2015. 15 years down the line, it is gratifying to be able to report on the success:
  • Reduce extreme poverty by half - it has been reduced by over 70% already
  • Achieve gender equality in education - achieved by 2012
  • Halve the proportion of the population without access to improved drinking water - bettered; it has been reduced by 60%
  • Reduce child mortality by two-thirds - only managed a 44% reduction by 2013
  • Reduce maternal mortality by three-quarters - only managed to halve by 2013
  • Universal primary education - up from 80% in 1990 to 92% in 2013
In September this year, there will be another such conference.  You would think that, buoyed by the success of the Millennium goals, they would see the merit of keeping things simple.  But no, this is the United Nations.  The September conference is to consider a new set of SustainableDevelopment Goals - 169 in all! Focused it is not. 

My hero, Bjorn Lomborg and his Copenhagen Consensus have tried to offer some prioritization. They have found 18 of the goals which have some hope of giving real value, mainly simple things like improving treatment of malaria, immunising more children against preventable childhood diseases and wider use of family planning.  

But far too many of the 169 are politically correct globspeak:
By 2030 ensure all learners acquire knowledge and skills needed to promote sustainable development, including among others through education for sustainable development and sustainable lifestyles, human rights, gender equality, promotion of the culture of peace and non-violence, global citizenship, and appreciation of cultural diversity and of culture's contribution to sustainable development.

As The Economist commented, "Try measuring that!"

Begone, prophets of doom!


The prophets of doom have a long history.  Job was prominent among those who suffered, yet remained confident even when his supposed friends told him the end was nigh. Recently, the breed has spawned a new source of doom - "The fossil fuel industry must be put out of business by 2050 to avoid dangerous climate change" intoned one David le Page recently in the Mail &Guardian. He is part of a long tradition of those who have advised abandoning all hope when facing difficulties.  Fortunately history has a message for him and his kind – the human spirit is such that it can rise to almost every challenge.

Le Page’s thesis is that if mankind consumes much more fossil fuel, the additional carbon dioxide in the atmosphere will cause the average global temperature to increase more than 2oC above what it was in the pre-industrial era before 1800.   It is a difficult thesis to substantiate, if only because we do not know exactly what the average temperature was in the early part of the 19th century.  We only started to have some idea of the global temperature around 1860, when calibrated thermometers became widely available.  Since then, it has warmed by a little over 0.8oC.

The million dollar question is how much of this warming is caused by added carbon dioxide.  Clearly not all of it, because the temperature shot up between 1910 and 1940, and there was little increase in carbon dioxide over that period.  So we don’t know how much extra carbon dioxide is likely to cause the atmosphere to warm by 2oC.  It seems decidedly irrational to propose getting rid of fossil fuels, all our coal, oil and natural gas, to achieve a target which is so ill defined.

Proposing to get rid of fossil fuels becomes even more irrational once you realize than nearly 90% of all the energy we use comes from fossil fuels, worldwide.  South Africa uses fossil fuel for nearly 95% of its needs. So the world cannot be weaned off fossil fuels overnight.  Indeed, right now the use of fossil fuels is growing rapidly, and that growth seems likely to persist as China develops, India follows and Africa finally takes off economically.

There is a direct relationship between economic growth and the consumption of energy.  When nearly 90% of your energy comes from fossil fuels, then there is an equally close relationship between economic growth and growth in fossil fuel use.  So in calling for restrictions on the use of fossil fuels, Le Page is in fact putting in a plea for less development.  That is all very well if you are part of the developed world, but if you are in the process of developing, and have millions living in poverty, then you actually view such pleas as highly irresponsible.

Events in India illustrate this very well.  When China announced it would start to curb its growth in emissions after 2020, and would aim for zero further growth after 2030, India went on record as saying it was not in the least interested in any curbs on emissions.  Its development problems were such that eliminating poverty was far more important than addressing climate change. Recently, it has banned foreign funding of Greenpeace and other non-governmental organisations which it saw as posing a “significant threat to national economic security.”  A decade ago, India was emitting about twice as much carbon dioxide as South Africa; today it is emitting about four times as much and growing at about 100 million tons per annum.

We must not underestimate the benefits of fossil fuel use. If the internal combustion engine had not come into widespread use during the 20th century, we would have seen massive starvation on earth.  In 1900, nearly half the area devoted to agriculture was used to grow fodder for draft and carriage animals.  By 1940, fodder was still vital.  Surprisingly, the largest use of horses in warfare was the German invasion of Russia in 1942, which involved about one million animals.  Fossil fuels have allowed us to convert huge tracts of land to the job of feeding people, not animals.  That, and the increase in productivity due to scientific farming, has meant that the supply of food has grown faster than the human population, so starvation is no longer a real threat for most people.

While renewable energy may have its place, we have to remember that modern economies need constant power.  The South African economy is stuttering right now because even the fossil fuel supply is intermittent.  Try to imagine what life would be like if the most of our power stopped the moment the sun went down.  Yes, we as individuals could probably cope with gas cooking and paraffin lamps or candles. However, most of the energy we generate does not go to individuals, but to keeping our developed economy going.  Less than 100 organisations in South Africa use about two-thirds of all the energy we produce.  Modern economies demand energy to generate wealth, and that energy needs to be available every hour of every day.  An intermittent supply is better than nothing, but much worse than a continuous supply.

Indeed, we can measure the cost of not having energy, and compare it to the cost of generation.  The loss of power early in 2008 hit the South African economy with about R75 for every kilowatt-hour that was lost.  Compare that to the approximately R0.60 that Eskom spends at present to produce a kilowatt-hour. It is infinitely better to have too much power than too little.

Of course, we need sustainable development. But there is no point in committing economic suicide in an attempt to sustain ourselves, as Le Page would have us do. According to the Brundlandt definition, “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Yes, we have to worry about future generations, but we also have to do so without compromising our ability to meet our own needs.  My generation coped with the previous generation’s love affair with the Mutually Assured Destruction of nuclear weapons.  I have every confidence that my children will cope with the far lesser threats of climate change in ways that will amaze us.

Just what IS “sustainable development”?


If there is one thing on which everyone agrees, it is sustainable development.  Yes, we all want development, and yes, we are all as green as each other and want development to be “sustainable”. But when you scratch the surface, you soon discover people talking past each other.  How can chopping down trees, or digging up gold, be sustainable? Suddenly you are guilty of deforestation or the rape of the earth. These are no longer innocent development pastimes.

It is a problem of definition.  Back in 1992, there was a great gathering in Rio, from which all manner of Declarations and Agendas flowed.  Sustainable development was based on the Brundtland concept - it was that which created no harm for future generations. Wonderful stuff, but totally impractical.  Leave the tree in the air or the gold in the ground so that your grandchildren may have trees or gold. Then they in turn will preserve them, so that their grandchildren may have trees or gold. Before you know it, the tree has died or the gold has been washed out to sea. Any benefit mankind might have had is lost. 

So when the great next gathered, in Johannesburg in 2002, they rethought their ideas of a decade earlier.  Now, they decreed, sustainable development was that which balanced social, environmental and economic development. That sounds wonderful.  But mankind likes black-and-white questions.  To ask people to find the right balance between red (social), green (environmental) and gold (economic) is just too complicated.

The result is a focus on just one of the three legs.  There are those for whom the environment is sacrosanct – you cannot possibly want to build more houses round the city, can you?  It would destroy a small wetland/the only known home of a butterfly/a pristine forest (choose one). But others want to build not just a few houses, but a whole village, complete with schools and clinics, because people need somewhere to live, don’t they? And just as the architect puts the final touches to his beautiful garden suburb, along comes the developer demanding office blocks and supermarkets and warehouses and flyovers.  The environmentalist groans and either turns his sights on the next piece of wondrous nature, or fights to have the wetland/butterfly/forest declared sacrosanct. Sustainable development is the loser.

There is a wonderful recent example of this phenomenon at work.  Most South Africans, and certainly all who receive electricity from our national grid, are aware that there is a shortage of generating capacity. There are power cuts, which the individual perceives as a grievous nuisance, and which the economist recognizes as a disaster. Every kilowatt-hour of power lost costs the economy about R75. What else can you make for 50 cents that is worth 150 times more to the economy as a whole?

But there is a little corner of our land where the shortage of generating capacity is not seen as an economic disaster.  It is our Department of Environment Affairs, which chooses this moment to declare that some of our generating capacity is putting too much dirt into the air. Eskom must shut down the power stations to fix the problem. It is not quite irrational for the Department to suffer from this manic focus on the environment, but their actions certainly demand analysis, psychological or otherwise.

It transpires that in a Gilbert-&-Sullivan kind of way, they have a little Act. The Regulations under that Act empower the Department to decree that a pipe may not emit more the X particles per unit volume of air. 

Posed in this way, you can immediately see two difficulties. First, what kind of pipe? Not one that you fill with tobacco, light and stick in your mouth. That is purposely designed to put lots and lots of particles into the air. Do they mean that pipe with holes in its side, stuffed with big lumps of coal, and clouds of smoke billowing into the air? Equally clearly not – that is a traditional polluter, called an mbawula, protected from modern legislation like all declared traditions. No, they mean a pipe belonging to Dirty Industry, because Dirty Industry is obviously the problem – if you have forgotten what sustainable development is supposed to mean.

Secondly, why is X a problem? This actually requires more careful analysis, because it seems obvious that X must be a problem because the Regulations say it is.  Think deeper, and this argument becomes very circular.  And if you go really deep into the question you discover that X is a problem because some American bureaucrat with his own little Act declared that it was. We obviously have to follow the Americans slavishly, don’t we? The American is armed with several roomsful of paper in support of X.  He had argued his case before American legislators like all bureaucrats in a democracy should be made to do. So X is good for America – but is it good for us?

The answer is probably not.  We don’t have years of data and thousands of diligent scientists to create roomsful of paper in support of our Act, let alone a parliament packed with skilled jurists able to hold bureaucrats in check.

What should we be doing, if we care about the environment and our society and development? Perhaps we should adopt a different model, one more in keeping with our status as a developing nation. Let us look to Britain rather than America. After disastrous smogs in the early 1950’s, Britain introduced the Clean Air Act in 1956. It required many industries and homes to burn smokeless fuel. In due course, it established smoke control zones, within which no smoke was permitted, and banned the emission of dark smoke everywhere. No roomsful of paper, just no visible smoke.  And the result was dramatically cleaner air, which was the desired environmental outcome. How simple! How easy to implement! How easy to police!

There is no need to call for straitjackets for our Department of Environmental Affairs.  Their insanity is purely temporary.  Let them sit down at their desks and rethink the way in which we achieve clean air – and sustainable development.
