Down the Hunger Spiral: Pathways to the Disintegration of the Global Food System
by Asaf Tzachor
CFR, University of Cambridge, agencies
For a precarious global agricultural system with powerful feedback loops, business as usual means widespread hunger and embedded systemic risk, writes Asaf Tzachor, research associate at the Centre for the Study of Existential Risk at the University of Cambridge.
It is a tragic irony that one of the harbingers and hallmarks of modern civilization may bring about its demise: the system of agriculture.
In pursuit of safe, sufficient, and nutritious food for Earth’s 7.7 billion human inhabitants, agricultural leaders have invested in high-yielding crop varieties, innovated methods of fertilization, irrigation, and cultivation, and expanded farmlands and rangelands.
With an agricultural system devoted as never before to a few staple grain crops that require little attention, and with the globalization of supply chains and agricultural trade, humanity''s reliance on this undiversified structure, on a limited number of exporting countries, and resource-intensive cropping systems, has grown critical. Universal nutritional security is now contingent on just a handful of agricultural commodities.
Inadvertently, the pursuit of food security has led to forest clearing of unprecedented scale, to habitat fragmentation and biodiversity loss, to collapse of fisheries, and to climate change. These, in turn, threaten to destabilize the global food system.
Civilization has steered itself into a seeming paradox: cropping, fishing, and livestock farming must continue to expand and intensify to meet the nutritional security requirements of a growing global population, yet such expansion will only accelerate the exploitation of Earth''s arable lands, potable water, forests, marine ecosystems, and fisheries, as well as global warming.
Scientific principles, however, restrain us from believing in paradoxes, tragic ironies, and unfortunate coincidences. Rather, the problems associated with modern food systems result from obscure feedback mechanisms: convoluted chains of cause-and-effect which tie together different components of the system in co-evolving, co-dependent relationships and breed, under certain circumstances, unintended consequences, detrimental domino effects, and cascading ecological crises.
Four Plausible Pathways to the Disintegration of the Global Food System
When discussing the global food system, not all causal mechanisms merit equal attention. Specific chains of cause-and-effect govern the system''s dominant behaviors, perpetuate its precarious dependencies and, through circular pathways, have the potential to undermine it. Any intervention should attend to these pathways first.
First Pathway: Demand for Agricultural Commodities driving Greenhouse Gas Emissions, Climate Change, Sea Ice and Ice Caps Melting, compounded by Forest Loss
Human hunger, naturally, should be our starting point: hunger inspires agriculture, and hunger is also the definitive point of reference to how well the system of agriculture performs.
While the particulars of hunger and nutrition have changed in the course of time, the fundamentals have not. The greater the population, the more mouths to feed. The greater the share that are middle-class [PDF], the stronger the appetite for food products from animal sources.
Over the past 50 years, daily intake of proteins and other essential micro-nutrients from animal products, a category that covers milk, eggs, cheese, chicken, meat, beef, sausages, fish and seafood, increased by 33 percent in high-income countries and surged by 116 percent in low- and middle-income countries. The UN Food and Agriculture Organization (FAO) expects both figures to continue rising.
The consequence of these demographic drivers and dietary preferences—not to mention government subsidies that reward the status quo and discourage farmers from innovating and diversifying land use—is an agricultural structure organized around four crops: wheat, maize, rice, and soybean, for food and animal-feed.
Together, these four items occupy roughly half of the global cropland under cultivation. Reinforcing this structure is the constant need to expand and intensity production, bringing more hectares under cultivation while increasing crop yields per hectare.
What follows is a domino effect with global implications. Cropping and livestock farming systems, it is now well-substantiated, are responsible for one-third of all anthropogenic greenhouse-gas emissions, from farming, manufacture of farming inputs, forest-to-farm conversions (deforestation), and other activities across the supply chain.
Over time, as the concentration of greenhouse gasses in the atmosphere has increased, temperatures have risen and more ice—in glaciers, the arctic sea, and tundras—has melted, resulting in decreased global surface reflectivity.
This has led to more solar energy absorption, higher ocean temperatures, more rapid sea ice melting, and so on. Earth can now lose 11 billion tons of ice in a single day.
Dissolving ice in the permafrost regions of the Arctic has reinforced this mechanism, via the release of sealed methane into the atmosphere. Global warming has accelerated as a consequence.
As the domino has tumbled, the frequency of forest fires has increased. In just 7 days in August 2019, 109,694 fire alerts were reported in Brazil. Calamitous events such as last summer''s burning of 1.6 million acres of Alaskan boreal forests have become alarmingly mundane.
Boreal forests, as critical "global carbon sinks,” remove large amounts of carbon-dioxide from the atmosphere. In incinerating these vital ecosystems, two months of Alaskan wildfire in 2017 discharged a hundred megatons of carbon-dioxide back into the atmosphere—roughly equivalent to the annual emissions of Belgium. Such fires intensify the vicious cycle.
Second Pathway: Demand for Animal-Source Foods Driving Collapse of Marine Ecosystems, Fisheries, and Fisheries-Dependent Livelihoods
Greenhouse gas emissions engender another causal mechanism in which carbon-induced ocean acidification, compounded with ocean warming and ocean salinity alterations from melting icecaps and glaciers, tamper with marine ecosystems and fisheries conditions.
The abundance of fish species with an affinity to cold climates appears to be decreasing in the Mediterranean, as does the size of the fish there, with severe implications for fisheries in the sea.
Overexploitation of oceanic fisheries adds to the predicament. Of the 600 marine fish stocks monitored by the FAO, 58 percent are fully exploited, with no room for further expansion. Thirty-one percent are overexploited at unsustainable levels, and a number of specific stocks have collapsed as a commercial resource entirely. North Atlantic cod and haddock, for example, are commercially depleted, and bluefin tuna is on the brink of depletion. Salmon is fully exploited.
In the eastern-central Atlantic, all species are overexploited. In the Indian Ocean, most fish families are either depleted or overexploited, and in the Pacific, most species are depleted or overexploited. The huge South China Sea fishery is on the verge of collapse.
One cascade effect of such relentless overfishing is the devastation of hundreds of millions of livelihoods that depend on fisheries directly and indirectly. On average, fish account for 17 percent of animal-protein intake globally. In some developing countries, this figure is as high as 50 percent.
In Bangladesh, for instance, a country of 164 million people, 71 percent of households consume fish, while 2 percent consume meat, according to the World Health Organization. Not only a nutritional source, the fishing sector provides some 50 million individuals with jobs and income; 12 million in Africa alone.
Fish are one of the most-traded food commodities in the world and they may even serve as a source of hard currency [PDF]. Fishery collapse could contribute to mass migrations, among other compounding effects.
Third Pathway: Climate Change driving Crop Failures, Forced Migration, Civic Unrest, and Conflicts, Compounded by Land Grabbing
Food security depends on agricultural yield stability, which in turn depends on crop tolerance to environmental stress factors. In destabilizing the global atmospheric regime and upsetting local and seasonal weather patterns, cropping systems will themselves become more vulnerable to variations in heat, humidity, and precipitation.
A seminal 2012 study found that changing weather conditions have already decreased the production of global wheat by 5.5 percent and maize production by 3.8 percent between 1980 and 2008.
Under increased environmental strain, increases in agricultural yield are poised to slow down. If and when they do, supplies will fall, prices will rise, and societies will become prone to famine, food riots, and conflict.
The International Food Policy Research Institute suggests that the 2007-2008 food crisis, whose effects became intertwined with those of the 2008 financial crisis, kindled civic unrest in 61 countries and led to violent riots in 23 countries.
Food insecurity was also a probable factor in the protests and violent revolts in Tunisia, Egypt, Libya, and Syria, known as the Arab Spring. In 2011, climate change provoked droughts in the Horn of Africa, prompting a regional food shortage that affected 13 million people, and claimed over 250,000 lives in Somalia alone.
As climate change continues, due in part to the agricultural system, environmental refugees and internally displaced people suffering from food scarcities, will migrate in greater numbers, contributing to xenophobic backlash and sociopolitical instability.
In such a geopolitical climate, investments in essential agricultural infrastructures for environmental adaptation would be discouraged, perpetuating vulnerabilities to extreme weather events, increasing the frequency of crop failures, and reinforcing the feedback loop.
Fourth Pathway: Agri-Food Supply Chains, Livestock Farming and the Formation of Self-Undermining Mechanisms; Climate Change, Extreme Weather Events, Pests, and Diseases
Adding fuel to the flames, climate change will punish entire food supply chains in at least three more ways. At the farm, warmer temperatures are primed to increase plant pathogens’ development and survival rates, their spread into new territories, and their hosts’ susceptibility to diseases.
Livestock disease, such as the Bluetongue virus and Rift Valley fever, might intensify in warmer climates too, and epidemics may become more frequent and widespread.
Across production, transportation, and storage lines; at farms, grain elevators, and silos, and en route to one place or another, extreme weather events will jeopardize the integrity of supply chains and damage critical infrastructures.
With climate change already in motion, anecdotes are abundant. In 2008 in Myanmar, Cyclone Nargis flooded 783,000 hectares of farmland, killed about 122,500 draft animals, and left some 52,000 farmers idle. In 2010, a drought decimated Russian wheat.
In 2012 in the United States, the network of locks and dams of the Mississippi River, through which maize, soybean, and wheat are exported, failed to cope with extreme rainfall, resulting in delays for commodity-carrying barges and leading to price surges. In 2017, Hurricane Harvey reduced rail services to Texas Gulf ports, halting regional grain exports. That same year, Hurricane Irma slashed Florida''s citrus production by nearly 23 percent, and in North Carolina, Hurricane Florence cut approximately $11 billion of farm sector cash receipts.
Recently, Cyclone Idai flooded some 2,165 square kilometers in Zimbabwe, much of which was under cultivation by subsistence farmers.
Climate change, to summarize, will increase the volatility of a global food market already engulfed in uncertainty. Sea level rise, meanwhile, will disrupt activities at export and import terminals thereby restricting access for international commodities shipping (maritime shipping accounts for about 80 percent of global trade by volume).
Like the ouroboros, the serpent eating its own tail, the global agricultural system as it exists today is poised to devour itself. The precarious system sets off a series of cascading effects that, by circular pathways and compounding reinforcing mechanisms, route back to destabilize all phases and functions of the food supply chain.
It is difficult to determine what the most defective part of this system is, but these four causal pathways offer a decent starting point.
We ought to entertain, furthermore, the possibility of converging causal processes: global warming, wildfires, ocean acidification, longer-duration droughts, harsher floods disrupting supply chains, faster spread of plant diseases and livestock epidemics, resource depletion, crop failures, sea level rise, accelerated migration of refugees, rising anti-immigrant populism, and sociopolitical instability–a perfect storm that would not only disintegrate the global food system but also shove billions into various forms of malnutrition.
A Failure of Governance and the Role of International Cooperation
Ultimately, the inadequacies of the global food system represent a failure of policy. Incremental modifications to the system, such as cropland expansion and agricultural intensification, the two predominant strategies of the global agricultural complex will not fix the problems of food insecurity and perilous ecological degradation.
Instead of perpetuating perverse systemic behaviors, dependencies, and distortions, scientists, technologists, policymakers, and other stakeholders should redesign food systems wholesale and act to mitigate the triple ecological-nutritional-social risks engendered by modern agriculture.
Here, systems-thinking can help. A reconfiguration of the global food system should take advantage of leverage points, places in the system where a minor adjustment in one element would result in substantial changes to the entire system.
Such smart systemic interventions should include an overhaul in the structure of incentives and government subsidies, to nip perverse systems behaviors in the bud, while allocating considerable capital to support agro-tech innovations and future foods as both food and feed sources.
National governments should strengthen regulation and supervision on land-grabbing, clamp down on illegal, unreported, and unregulated (IUU) fishing, and enhance international cooperative schemes and mechanisms to invest in rural agricultural infrastructures, promote agricultural self-sufficiency, and sponsor advanced agricultural research.
Multiplying the budget of CGIAR, the world''s largest global agricultural innovation network, would be a good start. And, in a time of great disruptions, we ought to prioritize Sustainable Development Goal 2.4, implementing resilient agricultural practices, with a greater focus on smallholder farmers in developing countries.
How many lives lost to hunger make a catastrophe? What is the humanitarian crisis threshold? A million fatalities? Ten million? Today, 821 million people endure a wretched life of undernourishment. In many respects, catastrophe is already upon us.

Failure to adapt to climate impacts will increase inequality
by Reuters, Global Commission on Adaptation, agencies
Failure to adapt to climate impacts will increase inequality. (Global Commission on Adaptation)
As the planet heats up, governments and businesses must radically rethink how they make decisions in key economic areas such as agriculture and infrastructure, said a flagship report aimed at pushing climate adaptation measures up the political agenda.
"If we do not act now, climate change will super-charge the global gap between the haves and the have-nots," said Ban Ki-moon, who co-chairs the Global Commission on Adaptation with philanthropist Bill Gates and World Bank CEO Kristalina Georgieva.
Former U.N. Secretary-General Ban said there were many opportunities to avoid losses caused by disasters and build economies that can better withstand wild weather like powerful Hurricane Dorian, which devastated the Bahamas this month. But far larger scale commitments from political leaders are needed Mr. Ban said.
Investing $1.8 trillion globally in early warning systems, more robust infrastructure, improved crop production, mangrove protection and resilient water resources between 2020 to 2030 could generate $7.1 trillion in net benefits, the report said. That amounts to an average of about $4 for every $1 spent.
"Failing to seize the economic benefits of climate adaptation with high-return investments would undermine trillions of dollars in potential growth and prosperity," it added.
Without adaptation, climate change could cut agricultural yields by up to 30 percent by 2050, hitting the world''s 500 million small farms the hardest.
And it could force hundreds of millions of people in coastal cities from their homes, while pushing at least 100 million people into poverty in developing countries by 2030, the report warns.
Yet despite the cost of not acting and the potentially "huge" returns from doing so, climate risks were still not being factored adequately into decision-making, said Andrew Steer, a commissioner and head of the World Resources Institute.
Poor people, in particular, should be targeted with help to adapt to climate change, as they are often the most harshly affected by disasters but "do not have a voice", said Steer.
Most funding for adaptation "never gets close to communities", he added, urging a radical overhaul of how that money is provided so it reaches those who need it faster.
The report outlined actions that could enable key economic systems affected by climate change - from food production and water supplies to the natural environment and cities - to function better and provide for a growing global population.
Former U.N. climate chief Christiana Figueres said a common excuse for not investing in adaptation was that it did not purportedly generate a direct revenue stream. But instead, it should be viewed like good public health - as a way of keeping economies safe and allowing them to grow. "The main message of this report is either we delay and pay, or we plan and prosper," she told journalists.
The current worldwide sustainable development model is threatening to reverse years of progress, if strategies don’t drastically change, an independent group of scientists has concluded in a major new report launched on Wednesday.
The UN report will be at the centre of discussions during the UN summit on the SDGs later this month.
Worsening inequalities and potentially irreversible damage to the natural environment on which we all depend, demands concerted action, the UN Department of Economic and Social Affairs (DESA), urged in a statement on the report findings, compiled by a team of 15 UN-appointed experts.
“Achieving human well-being and eradicating poverty for all of the Earth’s people—expected to number 8.5 billion by 2030—is still possible,” they highlighted, “but only if there is a fundamental—and urgent—change in the relationship between people and nature.”
The report, “The Future is Now: Science for Achieving Sustainable Development,” points to understanding the relationships between individual SDGs and the “concrete systems that define society today” to devise a plan to ameliorate global instability.
At the request of countries to evaluate progress of the 2030 SDG Agenda, adopted in 2015, the Global Report on Sustainable Development (GDSR) consists of surveys on scientific findings from ocean livelihoods, to sustainable consumption, production, and disaster risk management, among other issues.
The current roadmap for development has generated prosperity for “hundreds of millions,” the scientists said, but at the cost of other resources and a growing inequality that undermines global growth.
Boosting economies via increasing consumption for example, is exhausting the planet’s materials and creating toxic by-products which threaten to overwhelm the world. At the current rate of consumption, “use of material is set to almost double between 2017 and 2060, from 89 Gigatons to 167 Gigatons”, resulting in consequential “increased levels of greenhouse gas emissions, and other toxic effects” from resource extraction, they stressed.
The status quo must change, scientists said, in order to eschew further loss in “social cohesion and sustainable economic growth,” curb biodiversity losses, and save a “world close to tipping points with the global climate system.”
For this to happen, all sectors must come together in coordinated action, the report urges. Increasing investment in science for sustainability, is one key approach, and acknowledging that achievement of the SDGs requires economic growth be divorced from environmental degradation, while reducing inequalities.
The experts noted that “the extensive transformation that is needed will not be easy, and the report suggests that a deep scientific understanding is needed to anticipate and mitigate the tensions and trade-offs inherent in widespread structural change.”
Key points of intervention
According to the report, there are 20 points of intervention that can be used to accelerate progress toward multiple goals and targets in the next ten years.
Among these, basic services must be made universally available - healthcare, education, water and sanitation infrastructure, housing and social protection - as a prerequisite” toward eliminating poverty.
In addition, ending legal and social discrimination, scaling up trades unions, nongovernmental organizations, women’s groups and other communities will “be important partners in efforts to implement the 2030 Agenda”, the experts said.
Inefficient food and energy systems are depriving some 2 billion people of food security, while 820 million are undernourished, and 2 billion adults are overweight. Production processes are causing severe environmental impact.
Transitioning to renewable energy systems could help reduce the 3 billion who rely on pollutants for cooking, and avoid premature deaths, estimated at 3.8 million each year, they cited.
Meanwhile, the energy access gap has left close to one billion without access to electricity at all. Increases in renewable energy supply in the past decade have corresponded with price drops in clean fuel technology - around 77 per cent for solar power and a 38 per cent drop for onshore wind.
With an estimated two-thirds of the global population projected to live in cities by 2050, the experts said achieving the 2030 Agenda will require “more compact and efficient” urban areas that will be nature-based in infrastructure; but the ecosystem’s services and resources “must be safeguarded.”
What the scientists call “the global environmental commons” - the rainforests, oceans, and atmosphere - need support from governments, international actors and the private sector to ensure good practices.

Pope Francis says deforestation must be treated as a global threat. (Reuters)
Pope Francis said on Saturday rapid deforestation and the loss of biodiversity in individual countries should not be treated as local issues since they threaten the future of the planet.
Francis made his appeal on a visit to Madagascar, the world''s fourth-largest island, which research institutes and aid agencies say has lost about 44% of its forest over the past 60 years, abetted by illegal exports of rosewood and ebony.
Francis zeroed in on endemic corruption, linking it with persistent, long-term poverty as well as poaching and illegal exports of natural resources.
Addressing Madagascar''s president, Andry Rajoelina, his cabinet and other officials, Francis said some people were profiting from excessive deforestation and the associated loss of species.
"The deterioration of that biodiversity compromises the future of the country and of the earth, our common home," he said.
"The last forests are menaced by forest fires, poaching, the unrestricted cutting down of valuable woodlands. Plant and animal biodiversity is endangered by contraband and illegal exportation," Pope Francis said.
Jobs must be created for people whose livelihood harms the environment so they will not see it as their only means of survival, the pontiff added.
"There can be no true ecological approach or effective efforts to safeguard the environment without the attainment of a social justice capable of respecting the right to the common destination of the Earth''s goods, not only of present generations, but also of those yet to come," he said.
The Amazon fires have lent new urgency to Francis''s calls to protect nature, tackle climate change and promote sustainable development -- all themes enshrined in his 2015 encyclical on environmental protection.
Madagascar is one of world''s poorest countries. The U.N. Nations World Food Program estimates that more than 90% of its population of 26 million live on less than $2 a day, with chronic child malnutrition widespread.
Corruption is also rampant, Transparency International says.
Francis urged the nation''s leaders "to fight with strength and determination all endemic forms of corruption and speculation that increase social disparity, and to confront the situations of great instability and exclusion that always create conditions of inhumane poverty".
Conservation groups say that during Rajoelina''s first stint in power, his cash-strapped administration presided over a spike in deforestation to supply rosewood and ebony to China despite a national ban on such exports.
Environmental campaign group TRAFFIC estimates that at least one million rosewood logs have been illegally shipped from Madagascar since 2010. As Asian supplies of valuable hardwoods including rosewood used to make luxury furniture have been depleted, Chinese importers have shifted to Africa, according to Chinese customs data cited by U.S.-based non-profit group Forest Trends.
