Tackling food security with a growing population, climate change and peak oil

With a growing population and improving diets there is a need to double our food supply by 2050. Identify three measures you would take to meet this demand. Identify one of your measures from your list and post your solution into the discussion - be prepared to defend your choice!

That is a big question to throw in a climate change course. I am presently doing an online course - Climate Change: Challenges and solutions - offered by the University of Exeter (UK). So please indulge me as I also use this blog for some climate course work. This article is for week 6, section 6.5 of the course on 'Tackling food security'.

Food security is one helluva big area to try and come to terms with. Earth's population is just over 7 billion people. It is projected by the United Nations in a June 2013 report on global population to reach 9.6 billion people by 2050, although some commentators like David Merkel think it may peak at 8.5 billion around 2030 due to officials underestimating the fall in the fertility rate.

Currently, at least one billion people are constantly hungry or living under the threat of hunger.

Agricultural productivity of the last century has been brought about by the energy input from fossil fuels. There is a strong recent correlation between soaring food costs and soaring oil costs. With Peak oil, energy costs can expect to increase much further, placing further costs on food production. A FAO 2011 report says: "Commodity prices tend to be linked with global energy prices. As energy prices fluctuate and trend upwards, so do food prices".

Scientific breakthrough: Remove CO2 from pollution and atmosphere for alternate fuel

An improved method of removing carbon dioxide (CO2) cheaply from industrial smoketacks and even scrubbing the air has been discovered which may help in stabilising climate and reducing carbon emissions. Resolving the huge problem of climate change and global warming is going to take significant action on many levels. This new technology, if it can be rapidly developed and commercialised, may prove extremely useful in reducing carbon emissions and ultimately helping our society to become carbon negative. But the scientists have gone a further step and propose turning the captured carbon dioxide into an alternate stable fuel called renewable methanol to assist in resolving the peak oil petroleum resource depletion problem.

German Environmental Foundation announces Peak Oil is here.


Peak Oil is here and was reached in 2006, announced the Energy Watch Group in London on October 22, 2007. This simple statement will progressively affect our whole society, particularly our food production, energy and transportation systems. Demand for oil is already outstripping supply with the industrialization of India and China. Oil production is at capacity and will soon start to decline at an increasing rate. Crude oil hit $88 a barrel recently and is set to rise even further once the decline in production becomes apparent.

"The most alarming finding is the steep decline of the oil supply after peak", warns Jörg Schindler from the Energy Watch Group. This result, together with the timing of the peak, is obviously in sharp contrast to the projections by the International Energy Agency (IEA). "Since crude oil is the most important energy carrier at a global scale and since all kinds of transport rely heavily on oil, the future oil availability is of paramount importance as it entails completely different actions by politics, business and individuals.", says Schindler.

Until recently the International Energy Agency has denied that a fundamental change of energy supply is likely to happen in the near or medium term future. Hans-Josef Fell MP, a prominent Green Party member of the German Parliament said "The message by the IEA, namely that business as usual will also be possible in future, sends a diffusing signal to the markets and blocks investments in already available renewable energy technologies."

The Energy Watch Group was initiated by Hans-Josef Fell, Member of the German Parliament (deutscher Bundestag) since 1998, Speaker for the Energy and Technology Policy of the Parliamentary Party Alliance 90/The Green Party and Chairman of the Environment Committee, Nature Conservation and Nuclear Safety. Parliamentarians from other countries have since become involved in the organisation which is supported by the Ludwig-Bölkow-Foundation. Funding by the foundation allows project scientists to work on studies independently of Government and company interests concerning the shortage of fossil and atomic energy resources, development scenarios for regenerative energy sources as well as strategies deriving from these for a long-term secure energy supply at affordable prices.

The report says that remaining world oil reserves are estimated to be 1,255 Gb (Giga barrel) according to the industry database HIS (2006). But the Energy Watch Group (EWG) contradict this figure and say that there are sound reasons to modify these figures for some regions and key countries, leading to an estimate of 854 Gb. The EWG analysis is based primarily on production data which is more transparent and thus more reliable than reserves data which in the past have been frequently "adjusted".


Peak Oil is now, the report says, and it signals that human society is at the beginning of a structural change of its economic system. A sharp decline of fossil fuel supplies will influence almost all aspects of daily life according to the report. Climate change will also force mankind to change energy consumption patterns by significantly reducing the burning of fossil fuels.

The report warns that supply shortages could easily lead to disturbing scenes of mass unrest and a meltdown of society. "My experience of debating the peak oil issue with the oil industry, and trying to alert Whitehall to it, is that there is a culture of institutionalised denial in government and the energy industry. As the evidence of an early peak in production unfolds, this becomes increasingly impossible to understand", says Jeremy Leggett, the Solarcentury CEO and former member of the British Government’s Renewables Advisory Board.

Now the crunch is upon us with both peak oil and climate change. Time is fast running out for making structural changes in our energy and transport systems to cushion the impact of peak oil. And still we see Governments the world over committing resources to major road building when the prospects for road transport are looking particularly bleak with the projected increase in fuel prices as oil demand and prices skyrockets. Few Governments are pledging large scale expansion of the public transport and rail freight system which may soften the social impact of peak oil and reduce greenhouse emissions.

Most food production is now highly capital intensive and relies on oil as a fuel and as fertilizer products. When oil is too expensive to use, our farming techniques will need to adjust to smaller scale agriculture more dependent on human labour. Are you ready to become a farmer?

The business as usual scenario can only result in many people being hurt.




If you want to see an example of a society forced to experience peak oil, the Soviet withdrawal of support to Cuba after 1989 precipitated an oil crisis which forced food rationing, a major shakeup of public transport and agricultural systems. "The Power of Community: How Cuba Survived Peak Oil" is a documentary about how Cuba faced this crisis. Soon it will be our turn for the crisis. How ready are you? How ready are our governments? Do we really need expanded roads and taxcuts with a peak oil crisis looming?

The executive summary conclusions of the report say that:
  • Production will start to decline at a rate of several percent per year. By 2020, and even more by 2030, global oil supply will be dramatically lower. This will create a supply gap which can hardly be closed by growing contributions from other fossil, nuclear or alternative energy sources in this time frame.
  • The world is at the beginning of a structural change of its economic system. This change will be triggered by declining fossil fuel supplies and will influence almost all aspects of our daily life.
  • Climate change will also force humankind to change energy consumption patterns by reducing significantly the burning of fossil fuels.
  • The now beginning transition period probably has its own rules which are valid only during this phase. Things might happen which we never experienced before and which we may never experience again once this transition period has ended. Our way of dealing with energy issues probably will have to change fundamentally.
  • The International Energy Agency denies that a fundamental change of our energy supply is likely to happen in the near or medium term future. This sends a false signal to politicians, industry and consumers.
