A Climate Reality Check, on Social Collapse and Public Knowledge

‘Global Food Prices are Already Higher than for Most of Modern History’

Written by Alastair Smith

The Theory of Civilisational Collapse

Extinction and Rebellion, the global Climate Emergency campaign network, believe that Global Heating and associated Climate Breakdown has already locked in a likely “Social Collapse” (Reed 2020; Hallam 2019). To understand the potential for this, leading speakers such as Rodger Hallam argue, look at the failed state of Somalia (2019).

Potential pathways for such an unravelling of so-called “civilisation” include the collapse of asset prices for coastal property and the “fiscal crisis of the state”: the scenario in which ecologically catalysed recession is so deep, that the legitimacy of government evaporates as its capacity to fund welfare amid deep inequality is neutralised, and the poor cannot afford food (Hallam 2019). Based on their academic research and scholarship, Rupert Reed, Professor of Philosophy at the University of East Anglia, and Rodger Hallam, previously a researcher at King’s Collage London, also outline that we know exactly what happens to social stability when poor people lack food: they understandably secure their livelihoods in any way they can (Hallam 2019).

The ultimate end, Hallam (2019) suggests in talks given across the UK, is war. This might be across borders as hungry migrants move on scales the world has never seen (MPI 2020); it might be through internal conflict as citizens riot for food, facing little resistance where a police force and military have gone unpaid for long enough. If there is one robust law of social science, it is the one promulgated decades ago: revolutions happen when the masses go hungry (Risbridger 2018).

The Limits of Public Knowledge

For many, the sort of dystopian or apocalyptic visioning promoted by Extinction and Rebellion is inappropriate. Critiques refer to the fallacy of such a Malthusian’esk and neo-Malthusian theory that predicts significant social fallout when food demand outstrips food production. Commentators who prefer to celebrate the gains of human development, highlight that humanity has always triumphed in difficult times: “adversity is the mother of invention”, or so goes the often used, yet little reflected on saying of convenience.

Indeed, this is a privileged defence given that:

“The [UN’s] latest edition of the State of Food Security and Nutrition in the World…estimates that almost 690 million people went hungry in 2019 - up by 10 million from 2018, and by nearly 60 million in five years. High costs and low affordability also mean billions cannot eat healthily or nutritiously”(FAO 2020).

Not only has the frequency of malnutrition grown in recent years, much of the most intensive nutritional deprivation is also inextricably interconnected with violent conflict (GAIN 2020). The causation between food availability and violence is of course complex, but only those with the fortune not to experience this nexus for themselves have the privilege to dismiss its relevance out of hand.

Moreover, the vast majority of the world has failed to notice a dual indictment of the current nature of human “progress through innovation”: that illustrated by the role of information, knowledge and education, a much-praised characteristic of democratic organisation and widely hailed as part of the “white” Northern world’s defence against social collapse.

Empirical Realities of Food Markets in 2021

As part of my scholarship for research-led teaching on food, security, sovereignty and sustainability, I have paid constant attention to the United Nation’s Food and Agriculture Organisation’s (FAO) regular reports on crop production, consumption and stocks, as well as their individual and collective prices (FAO various). In classes, I have elicited students’ current knowledge of food dynamics before challenging them with the more accurate realties. As part of this exercise, those learners thinking of themselves as well-informed find most headlines and graphical representations rather unsurprising.

To take a few examples of the insights we all might find familiar:

  • “As more go hungry and malnutrition persists, achieving Zero Hunger by 2030 in doubt, UN report warns” (FAO 2020).
  • “Prices are at the highest since 2014, risking faster inflation” (Bloomberg, May 2021).
  • “Global food prices rise for 10th month in a row (April ReliefWeb 2021)”.
  • “Most food commodity prices are gaining momentum as end-2020 approaches” (World Bank 2020).

Since I started writing this blog, some analysis has started to become more pertinent, with the more accurate soundbites that:

  • “UN: Cost of food rises at fastest pace in over a decade” (BBC 2021)
  • “Global food prices post biggest jump in decade” (Financial Times 2021)
  • “Global Food Prices Keep Rising…The May figure is the highest of any month in almost ten years”.

Sadly, while more precise than previous accounts, this messaging still misses the simple statistical observation that obliterates the relevance of this coverage. Reviewing the “real” price of food over time – expressed as an index relative to a base year, rather than the nominal value in currency, which makes comparison harder due to inflation – the only relevant way to capture today’s status of global food prices is to say that:

‘It is on average harder to buy food today in 2021, than it has been since 2012, and in fact for most of the noughties, the entire decade of the 1990s, andthe 1980s; mostof the 1970s, and every year of the 1960s! Food is more expensive today than it has been for most of the modern recorded history’.

Even though the FAO has not coined this summary, its own graphic representations show the gravity of our current reality. While the FAO’s version can be seen at the bottom of their recent webpage (2021), below is my most recent reproduction, as I share with my students. Here the graph shows the most recent 2021price index calculation in blue, thus allowing easy visual comparison with the historical trend, shown in grey.

Here we see that apart from the food price crisis of 2012, and the oil price crisis of the 1970s, today’s real costs of buying food are higher than almost the entire period since records began in 1961. This also means that the real price is also now higher than in 2010, when food shortages and interrelated price crisis gave rise to what the European media labelled as the “Arab Spring”, in which multiple North African governments were overthrown (Zurayk 2011).

Beyond this, knowledge creators and distributors have been fixated on COVID as the reason for recent price increases. This is again as well illustrated by a Google search for information, which returns summaries such as:

“Global food commodity prices in a post-COVID world” (World Bank 2020)

“The prices of raw materials that go into morning staples have surged since the start of the pandemic” (FT May 2021).

It is certainly true that COVID has disrupted global food supply (Loborde et al 2020), however, this framing disregards a much more prominent theme, identified by FAO crop reports that provide explanations about the dynamics of supply and demand. For the most part, these regular briefings are written in fairly technically and arguably obscurantist language: here you’ll find expressions that attribute price rises to “increasingly tight global supply with lower-than-earlier-expected production and stock estimates…”.

However, when you move past these broad expressions you find others that explain the problems of food production: “Concerns over dryness in South America” (FAO 2021), “owing to poor weather conditions that curtailed yields” (2021a), “continued dry weather has partially curbed prospects, and field reports confirm inferior crop conditions compared to the average” (2021a). Put simply, one of the most prominent themes in FAO analysis has been the unpredictability of weather and the manifest inability of technology to full mitigate for this.

It is of course important not to be alarmist. This analysis is not sufficient to conclude that unpredicted weather results from climate breakdown, which is already undermining our collective ability to produce enough food. It is true that in recent years declining supply of some key commodities - such as cereals that provide nutrition for c.50% of the human species – has been outstripped by growing demand, therefore literally eating into global buffer stocks. However, buffer stocks do exist for this very purpose and there will always be periods of over demand: the situation remains stable because supply is sufficient to meet needs over the longer term.

What this empirical reality does clearly demonstrate however, is that when weather is hard to predict, for example where long-term climate patterns change, and continue to change as is increasingly predicted by leaked updated IPCC consensus science (Harvey 2021), producing enough food to feed a growing population will be increasingly challenging.

In summary, five overall conclusions emerge:

  1. It is indisputably now harder to buy food in 2021, than it has been for most of modern history, and this should be reflected in headlines and sound bites. Moreover, malnutrition is growing not declining, and many of the most severe situations are interlinked with violent conflict. This is a damming indictment of the much-celebrated human potential.
  2. Climate breakdown will continue for decades irrespective of any actions taken now or soon, and there is evidenced risk to our food systems and supply will be compromised in the future. It is likely that buffer stocks will be consumed, and prices will rise, therefore excluding more and more of the world’s poorest people, creating a context for local and international social instability (FAO 2020).
  3. The end of “civilisation”, if and when it comes, very likely involves food riots and conflicts of a significant magnitude; a situation potentially catalysed by global pandemic (Bostrom & Cirkovic 2011). We will only know which crisis will be the last when it’s far too late to act.
  4. Minimising further climate breakdown is an essential risk management strategy to avoid risks to our food system, and everyone has the responsibility to pressure for radical changes by those meeting at the Conference of the Paris (COP) 26 event in Glasgow this year.
  5. Finally, we like to think we know about the Climate Emergency and its impact on our lives. However, the institutions we trust to provide appropriate information do not always tell us the whole story. Look past the headlines and the received opinion: your ability to see social collapse before it arrives might well depend on it.

    The FAO have updated their annualised data for September 2021. The Real Price Index of Average Global Food Prices has predictably continued to rise to 121.1 and will certainly further grow in the coming months.


    This means that in ‘Real Terms’ food is now more expensive than at any other time in modern history, apart from 1974 and 1975, when costs were driven by the oil price crisis.

    See updated graph here:

    While the continued rise of Real Food Prices is causally related to supply chain disruption following the impacts of COVID19, the price had already started to rise before the first reported outbreaks in December 2019; the FAO reports from this period are clear this was partly due to unpredictable weather.

    Where the Climate Emergency intensifies, as now fully predicted by the latest IPCC report, there will be increasing chances of food supply contraction. In the face of continued and rising global demand for food, this will reduce buffer stocks, further driving prices upwards as market react; this is especially where food is used as a financial asset. In this scenario, there is increased probability of the events likely lead to Social Collapse in various contexts, as food shortages combine with unsustainable levels of inequality of opportunity that the poor and disenfranchised will finally refuse to accept; the process of which we have seen in South Africa.

    Action on the Climate Emergency fundamentally relates to your food, financial and social security. Demanding and forcing drastic and radical action at COP 26 cannot be left to others.
