“For a long time, people have known that chemical pollution is a bad thing. But they haven’t been thinking about it at the global level. This work brings chemical pollution, especially plastics, into the story of how people are changing the planet.”

a huge number of chemical compounds registered for use – about 350,000 – and only a tiny fraction of these have been assessed for safety.

the total mass of plastics now exceeds the total mass of all living mammals

“Shifting to a circular economy is really important. That means changing materials and products so they can be reused, not wasted.”

There are growing calls for international action on chemicals and plastics, including the establishment of a global scientific body for chemical pollution akin to the Intergovernmental Panel on Climate Change.

“The rise of the chemical burden in the environment is diffuse and insidious. Even if the toxic effects of individual chemicals can be hard to detect, this does not mean that the aggregate effect is likely to be insignificant.“Regulation is not designed to detect or understand these effects. We are relatively blind to what is going on as a result. In this situation, where we have a low level of scientific certainty about effects, there is a need for a much more precautionary approach to new chemicals and to the amount being emitted to the environment.”

The chemical pollution planetary boundary is the fifth of nine that scientists say have been crossed, with the others being global heating, the destruction of wild habitats, loss of biodiversity and excessive nitrogen and phosphorus pollution.

"I don't think we will be able to investigate them all," Uzumcu said, highlighting the difficulties of working in a conflict zone.

By directly acquiring mines, accumulating equity stakes in natural-resource companies, making long-term agreements to buy mines’ current or future production (known as “off-take agreements”), and investing in new projects under development, Chinese firms traded much-needed capital for outright control or influence over large shares of the global production of these resources. Despite China’s slowing growth and a major pullback in its foreign direct investment in other sectors, the government has maintained robust financial support for resource acquisition; mergers and acquisitions in metals and chemicals hit a record high in 2018.

China lacks significant reserves of three resources vital to its tech ambitions: cobalt, platinum-group metals, and lithium. It has successfully employed two strategies to secure control of them. One is driven by China’s state-owned enterprises (SOEs), which use development finance and infrastructure investment to embed themselves in higher-risk countries, establishing close ties with government leaders. The second is investment by state-linked private firms in market-based economies. Both strategies have shown agility and an ability to effectively adapt to local circumstances to achieve the same end.

Chile is home to 57 percent of the world’s known lithium reserves, the world’s largest known concentration, and SQM controls roughly half the country’s production

DRC is home to nearly two-thirds of the world’s cobalt production and half of its known reserves. Those resources are the prime target of investors for the booming battery industry. Over a decade of steady engagement, China has staked out a dominant position by developing strong political ties and investing in production assets and related infrastructure

China’s SOEs and private firms have made at least eight major equity and off-take plays in platinum-group metals in the Bushveld Complex. Such investments in South Africa’s highly concentrated and strategic resource deposits have helped make metals the country’s leading source of export growth, with nearly 50 percent of its metal exports going to China—tying South Africa’s economic welfare directly to Chinese investment.

the three countries where nearly 90 percent of global lithium production and more than three-quarters of the world’s known lithium reserves are located: Chile, Argentina, and Australia. In just six years, China has come to dominate the global market: More than 59 percent of the world’s lithium resources are now under its control or influence

China now owns or has influence over half of the DRC’s cobalt production, and has a massive stake in its mining industry. Six months ahead of the presidential elections, the event also sent a strong message to candidates about China’s deep investment in copper and cobalt mining—which constitutes 80 percent of the DRC’s export revenue and thousands of jobs—and its capacity to influence the future of the DRC’s economy

Though the final agreement included restrictions on Tianqi’s board and committee participation and its access to SQM’s sensitive data, Tianqi’s equity position still confers considerable influence over SQM.

In a cash-strapped industry, Chinese firms are financing mine expansion and new development in exchange for a guaranteed supply of lithium in both mature and emerging markets. In Argentina, where President Mauricio Macri is eliminating mineral export taxes, reducing corporate tax rates, and allowing profit repatriation, China is establishing a dominant position in the nascent sector with “streaming deals,” which provide development capital in exchange for future lithium yields to help projects get off the ground. Chinese firms, led by Ganfeng, have stakes in 41 percent of the country’s major planned projects that account for 37 percent of Argentina’s reserves. This raw-material strategy is already coming to fruition: Lithium export volumes from Argentina to China rose nearly fourfold from 2015 to 2017, and China has secured access to the country's lithium for the longer term.

This same strategy, combined with asset acquisition, has also been successful in Australia, whose proximity to China, significant lithium reserves, and broad political support for mining investment have attracted Chinese investment. Tianqi and Ganfeng have established stakes in 91 percent of the lithium mining projects underway and 75 percent of the country’s reserves, including some of the world’s largest.

Natural resources are abundant in China; it is the No. 1 producer and processor of at least ten critical minerals and metals that are essential to high-tech industries and upon which China’s commercial and strategic competitors depend. To reinforce its strength, Chinese firms are acquiring mines and output from the next-largest producers and reserves, giving China both an economic edge in the next high-tech industrial revolution and increasing geopolitical power.

Perhaps the best-known example both of China’s natural-resource dominance and its willingness to exploit it is rare-earth elements, a group of 17 elements that (despite their name) are commonly found, but rarely in concentrations that can be economically extracted. They are important materials for the defense, aerospace, electronics, and renewable energy industries. Over the past two decades China has produced more than 80 percent of the world’s production of rare-earth elements and processed chemicals. In 2010 it cut off exports to Japan amid rising tensions over the East China Sea, and the following year it imposed export quotas that threw governments and manufacturers into a panic. But with the exception of Japan, the attention to this critical vulnerability was short-lived, and little action was taken by other countries reliant on imports to diversify their resources or develop minerals action plans of their own.

China declared rare-earth elements a strategic resource in 1990 and prohibited foreign investment in the sector. Six state-owned enterprises control the industry, and the government cut production quotas in 2018 by 36 percent. With global demand for rare-earth elements projected at a compound average growth rate of more than 17 percent to 2025, a supply crunch is likely approaching—and China is already securing other nations’ supplies

While Russia strictly limits foreign participation in rare-earth element development, Chinese firms have accumulated off-take agreements and stakes in rare-earth element mines in Australia and Brazil

in 2017, China’s Shenghe Resources and two U.S. private equity firms acquired the sole U.S. and North American rare-earth element producer and processor, Molycorp, and its idled mining operations at Mountain Pass, California.

In 2016, China’s Yellow Dragon Holdings Ltd. co-invested with Bushveld Minerals, the primary vanadium developer in South Africa’s massive Bushveld Complex, to acquire Strategic Minerals, which owned the Vametco vanadium mine and plant. Yellow Dragon subsequently increased its investment in Bushveld Minerals and has become the fifth-largest shareholder. The holdings deepen China’s influence over South Africa’s vanadium resources and its role in the country’s emerging high-tech sector

China’s position is even stronger in graphite, a crystalline form of the element carbon whose high conductivity makes it a major component in electrodes, batteries, and solar panels, as well as industrial products such as steel and composites. For the last 20 years, China has been the leading global supplier of graphite, representing nearly 70 percent of the world’s production in 2018 and 24 percent of its reserves. While synthetic graphite, which is produced from petroleum coke, is an alternative, unfavorable economics constrain its use

New projects are concentrated in Mozambique, where the world’s largest graphite mine and fourth-largest known reserves are located. Already, Chinese firms have secured off-take agreements with the three major developers in Mozambique for the majority of their graphite production, and they are financing new development.

Japan is 90 percent reliant on China for its graphite

This resource consolidation could determine whether China is able to overcome the last major hurdle to achieving its ambitions: a competitive semiconductor industry.

Semiconductors can be pure elements or compounds and altered with impurities to improve their conductivity. Several materials are now being used to improve speed and performance, including rare-earth elements, graphite, indium, gallium, tantalum, and cadmium. China is the dominant producer of five out of the six, controls more than 75 percent of the world’s supply of three, and is consolidating control over them all

Should China succeed technologically, its capacity to scale production and flood markets (as it has already done with solar panels and wind turbines) has serious implications not only for leading semiconductor producers, but also for national security, if Chinese-manufactured chips are embedded in the devices upon which our data-driven lives, our economies, and our defense systems increasingly depend. While government and industry officials have started to restrict semiconductor sales and scrutinize Chinese acquisition of technology firms—e.g., the United States’ temporary ban on selling semiconductors to ZTE, or the recent flare-up over Huawei —such moves are strengthening China’s resolve to develop its domestic industry. More attention should be paid to its efforts to consolidate critical raw materials and the computing power they confer.

In April, U.S. government officials announced plans to meet with lithium industry leaders and automakers with the intention of developing a national electric-vehicle supply chain strategy. It is a start.

China’s monopoly can be largely attributed to its relatively low energy costs and less stringent environmental regulations.

a single country, China, has gained control over much of the world’s production and processing of the cobalt, graphite, lithium, manganese, and nickel used in lithium-ion batteries, the type of electricity-storage devices favored by electric-vehicle manufacturers today.

Chinese companies now control almost half of the DRC’s cobalt output, which constitutes over two-thirds of the world’s production. Perhaps of greater concern, China has come to dominate the refining and processing of those minerals. Eighty percent of the cobalt sulphates and oxides used for lithium-ion battery cathodes are processed in China.

OPEC and Russia bargained for months, but talks finally broke down after Moscow refused to limit its oil production to help stabilize oil prices in the wake of the slump in global oil demand caused by the COVID-19 pandemic. Calculating that it could hurt Russia enough to force it back to the negotiating table, Saudi Arabia boosted its daily oil output by 20 percent, flooding the market with oil. Not to be intimidated, Russia responded with a short-term increase in its own oil output (possibly to strike back at Saudi Arabia or to force some American shale-oil companies out of business or both). As a result, oil prices collapsed. The futures price for West Texas Intermediate crude touched a remarkable -$37 per barrel. Although beneficial for oil consumers, the Russia-Saudi Arabia oil price war was a reminder of the influence that state-driven oil producers still had over the world’s energy security.

Though China controls a smaller share of the world’s production of lithium than that of other minerals, it has been buying up stakes in lithium mines around the globe.

Moving up the value chain, it is expected to build 101 of the 136 lithium-ion battery manufacturing plants that are currently planned over the next decade

n 2010, China abruptly restricted its rare-earth metal exports to Japan, nominally to protect the environment. But after a lengthy review, the World Trade Organization ruled against China’s restrictions. Since then, worries about relying on China as a strategic-minerals supplier have continued to grow. Sometimes, China feeds those fears. In one 2019 incident, China’s state-run Global Times flaunted the country’s dominance over rare-earth metals as a strategic weapon against other countries with the headline “China gears up to use rare-earth advantage.” Such not-so-veiled threats from government-linked media only fan suspicions that China will behave no better than Russia or Saudi Arabia—and possibly worse.

In 2019, the U.S. Department of State launched the Energy Resources Governance Initiative to “promote resilient and secure energy resource mineral supply chains” for all kinds of renewable energy and battery storage technologies.  The initiative’s membership has grown to include Australia, Botswana, Canada, Peru,

the world appears to be swapping its old dependency on OPEC and Russia, a fractious bunch that until recently was losing power to American oil-shale upstarts, for a new one on China, a single country with a one-party government

AGRA, initiated in 2006, heralded a new campaign to bring the kind of input-intensive agriculture to Africa that had failed to take hold on the continent when the first Green Revolution swept through much of Asia and Latin America in the 1960s and 1970s.

AGRA worked with governments to speed the development of high-yield commercial seeds designed for Africa’s wide range of soils and climates and to facilitate the delivery to farmers of those seeds and the inorganic fertilizers that would make them grow.

Many warned that it was seeking to impose Western technologies inappropriate for the continent’s soils, farmers and food systems. Some decried the lack of consultation with African farmers on the nature of the interventions.9 Others pointed out the serious flaws in the first Green Revolution: water supplies depleted and contaminated with chemical runoff; farmers indebted due to high input costs while yields declined after their initial increases; and the loss of crop and diet diversity as Green Revolution crops took over the countryside

African farm groups like the Alliance for Food Sovereignty in Africa (AFSA) also warned of the loss of food sovereignty, the ability of communities and nations to freely choose how they wanted to feed themselves, as large commercial firms could come to dominate local markets backed by new government policies designed to ensure market access.

Only one country, Ethiopia, shows anything resembling the combination of yield growth and hunger reduction Green Revolution proponents promised, with a 73% increase in productivity and a 29% decrease in the number of hungry. Note, however, that neither of these is on track to meet AGRA’s goal of doubling productivity (100% increase) and halving the number of hungry (which would be a 50% decrease). Ghana is the only other AGRA country that shows decent productivity growth with some decrease in hunger. Malawi achieved relatively strong yield growth but only a small reduction in undernourishment.

These data suggest that Green Revolution programs have not produced a productivity boom through intensification but rather an extensification onto new lands. The promotion of extensification is a serious contradiction for Green Revolution proponents. The explicit goal of “sustainable intensification” is to minimize pressure on land and water resources while limiting further greenhouse gas emissions. To the extent Green Revolution programs are encouraging extensification, they are at odds with national and donor government commitments to mitigate climate change. Depending on individual countries’ land endowments, extensification can be a serious problem. Rwanda, for example, is densely populated and does not have vast tracts of uncultivated arable land.

Evidence would suggest that the main beneficiaries are likely not the poorest or most food-insecure farmers but rather a growing number of medium-scale farmers who have access to more land and are already integrated into commercial networks. Only a fraction of such farmers come up from the ranks of smallholders; many are new investors in farming from urban elites. One study showed that a tiny fraction of smallholders is likely to become commercial farmers.18

Cassava, a key staple in Nigeria, Mozambique, Uganda, Tanzania and many other AGRA countries, saw a 6% decline in yields. Overall, roots and tubers, which include nutritious crops such as sweet potatoes, experienced a 7% decline in yields. Groundnuts, another critical staple source of protein in many countries, saw an alarming 23% drop in yields.

The Staple Crop Index shows that Rwanda’s apparent success in maize has come at the expense of more comprehensive food crop productivity.

The total number of undernourished in AGRA’s 13 countries has increased from 100.5 million to 131.3 million, a 30% increase, from before AGRA to 2018. Only Ethiopia, Ghana and Mali report a significant decline in the absolute number of chronically hungry residents

One of the negative consequences of the Green Revolution focus on maize and other commodity crops is the declining importance of nutritious and climate-resilient crops like millet and sorghum, which have been key components in healthy diets. These are rarely supported by African governments or AGRA; meanwhile, input subsidies and supports for maize and other favored crops provide incentives for farmers to decrease the cultivation of their own crop varieties

AGRA seems to be feeding Africa’s worrisome trend toward locking in path dependency on input-intensive agriculture, much to the detriment of smallholder farmers

Unlike industrial-scale farmers in developed countries, their path has not yet been determined; there remain opportunities to chart paths different from the high-input agriculture model promoted by AGRA.

Agroecology is one of the systems giving farmers the kinds of innovation they need, farming with nature to promote the soil-building practices that Green Revolution practices often undermine. Building on farmers’ knowledge of local conditions and food cultures, multiple food crops are grown in the same field. Compost, manure and biofertilizers — not fossil-fuel-based fertilizer — are used to nourish fields. Biological pest control decreases pesticide use. Researchers work with farmers to improve the productivity of their seeds rather than replacing them with commercial varieties farmers need to buy every year and douse with fertilizer to make them grow.25 AFSA has documented the effectiveness of agroecology, now widely promoted among its member organizations as a key step toward food sovereignty.26 Such initiatives also achieve productivity increases more impressive than those achieved by Green Revolution programs. One University of Essex study surveyed nearly 300 large ecological agriculture projects across more than 50 poor countries and documented an average 79% increase in productivity with decreasing costs and rising incomes.27 Such results far surpass those of the Green Revolution.

It is time for international donors and African governments to change course, to shift their agricultural development funding toward the kinds of low-input sustainable farming that many small-scale farmers in Africa are pioneering under the banner of agroecology. With substantial support, like that provided to Green Revolution programs, agroecology can be Africa’s food future

a rather modest account of American "core interests" in the Middle East and North Africa: countering military aggression against U.S. partners in the region, protecting global energy reserves, and confronting the dual threats of terrorism and nuclear proliferation

The United States of America is prepared to use all elements of our power, including military force, to secure these core interests in the region," he said. "But I also believe that we can rarely achieve these objectives through unilateral American action -- particularly with military action. Iraq shows us that democracy cannot be imposed by force. Rather, these objectives are best achieved when we partner with the international community and with the countries and people of the region."

is it possible that those who called for swift U.S. intervention several years ago were right all along? If the United States, NATO, the Arab League, or some combination of the above had established a no-fly zone and stood ready to intervene with ground forces, might the Assad regime have fallen quickly and spared Syria and the world this bleak and open-ended disaster?

I still believe intervening in Syria was not in the United States’ interest and was as likely to have made things worse as to have made them better. I take no pleasure in my conclusions; it would be more comforting to think that even seemingly intractable problems can be solved.I take no pleasure in my conclusions; it would be more comforting to think that even seemingly intractable problems can be solved

The Limits of Air Power. Proponents of “no-fly zones” typically exaggerate their impact and in so doing overstate the capacity of air power to determine political outcomes.

Assad’s “Gamble for Resurrection.” From the very start, a key problem in Syria was the lack of an attractive exit option for the entire Assad regime. As the titular leader of the Alawite minority that has dominated Syria since 1970, Assad and his followers saw relinquishing power as a mortal threat.

What About the Jihadis? Intervening to push Assad out faced another obvious objection: It might open the door for al Qaeda or other violent extremists. This concern also complicated proposals to arm anti-Assad forces like the Free Syrian Army. How could Washington ensure U.S. weapons didn’t end up in the wrong hands?

only thing worse than a truly awful government is no government at all

Face It: The United States Is Toxic. The ineffectiveness of U.S. training efforts and other forms of advice may be partly due to the negative opinion most people in the Middle East have of U.S. policy. America may be admired for its democracy, its achievements in science and technology, and the friendliness of its people, but U.S. Middle East policy is widely reviled.

Whose Interests Are Truly Engaged? There is a clear humanitarian interest in ending the Syrian civil war. But neither great nor minor powers typically run big risks or bear large costs for strictly humanitarian reasons.

the least bad option at this point would be a re-energized effort to end the fighting. The United States should stop insisting Assad must go, and listen carefully to the other powers with a stake in the outcome, including Russia

I don’t know if it will be possible to reconstitute a unified Syrian state; if not, then an organized and internationally supervised partition plan will have to be negotiated and implemented

The S.D.F. offers a remarkable vision to counter ISIS’s draconian rule — local councils, farmers’ cooperatives, and committees that promote the rights of oppressed minority groups. In the village of Jinwar, a female-controlled town, the S.D.F. has built a commune for women and their children, both Kurdish and Arab, seeking to escape oppressive families and realize a community without patriarchy. According to the constitution of the so-called Autonomous Administration of North and East Syria, the S.D.F.-linked ruling authority in the region, a post-ISIS Syria will be “a society free from authoritarianism, militarism, centralism and the intervention of religious authority in public affairs.” In order to realize this vision, part of the S.D.F.’s mandate is not just to govern, but also to annihilate ISIS. Several soldiers and S.D.F. spokesmen told me that the war against ISIS isn’t over — its aim now, with the support of the U.S., is to destroy sleeper cells and root out the ideology.

If we portray certain enemies solely as existential threats, we sweep over the political conflicts unfolding in places like Iraq and Syria, and the political violence wrought upon these communities, even by those who claim to be fighting a just war.

If our enemy is everywhere, we will seek allies in even the most oppressive of regimes (like Egypt and Saudi Arabia) to hunt down “terrorists,” no matter if they are gun-wielding militants or political dissidents who believe that the current state of affairs does not serve them.

If a war is a “good war,” or merely conceived of as a necessary one, it matters little why a terrorist group gained support, or how we may be inadvertently contributing to the group’s appeal. Yet, while the current approach to terrorism has been wildly successful in building a cottage industry of extremism and deradicalization experts, it has failed to rid the world of terrorists.

Massacres of Iraqi civilians, deaths of Afghan civilians by airstrikes, and indiscriminate detention and torture and rape have all happened at the hands of state security forces, including those allied with the U.S.

The Manichean framework helps absolve the West of its role and its responsibility in ending an endless conflict. “Terrorism” has become so synonymous with horrific violence that most Americans are likely unaware that the vast majority of civilian deaths in global conflicts today are caused by states, not non-state actors.

As with other battles against evil, the “killers and fanatics” necessitated the dropping of bombs, an operation that Obama’s successor continued.

a core argument for the war depended on the idea that terrorism was, in essence, a form of religious violence

What the Bush administration argued, and what the media accepted, was that terrorism is not a mere tactic, but a full-blown ideology — what Bush called “the heirs of all the murderous ideologies of the 20th century,” including “fascism, Nazism and totalitarianism.” In practice, this means non-state armed groups not allied with the U.S. should be understood as terrorist organizations — no matter if, like the Taliban, Hezbollah, Al Qaeda, and Hamas, they have little else in common

By and large, the media accepted the Bush administration’s framing. By 2006, public criticism of the handling of the Iraq War was mounting, but even then, few questioned the legitimacy of the war itself. In a 2009 study of media coverage after 9/11, two scholars from the University of Texas found that journalists “helped brand the policy, [then] labeled the frame as public opinion,” ultimately contributing to the acceptance of that frame as a “fact of life,” and a “larger narrative of struggle and heroism.” Journalists did not treat the War on Terror as a policy decision made by the Bush administration, but as the natural and inevitable order of things. 

The political scientist Austin Doctor recently conducted a study of sexual assault by 143 rebel groups around the world, from 1989 to 2011, and separately applied the results of his analysis to ISIS.  He found a correlation between the presence of foreign fighters and increased incidence of sexual violence, which suggests that the Islamic State functioned much like other rebel groups — that ISIS is not so singular as it may seem.

mainstream media coverage of ISIS receives almost no scrutiny. But many other publications and reporters have operated on the same flawed assumptions and premises as Caliphate, ones that animated the West’s understanding of the Middle East long before ISIS gained its first foothold

the issue here isn’t just the violence — after all, Assad has also relished the torture, starvation, and murder of his citizens. Since 2011, his regime has used chemical weapons repeatedly, more than three hundred times according to one study. The critical difference is that while Assad depends on the international system for legitimacy (Russia and Iran are key supporters, and Syria remains part of the global financial system), ISIS rejects it. While Assad would prefer that the world looks away, ISIS practically begs us to stare. It aims to demoralize Western audiences, while projecting to potential recruits its vision of a new world order

In parts of the Caliphate, ISIS did promise a different model, at least nominally. In one piece of propaganda, the group declared, “The people are as equal as the teeth of a comb. There is no difference between the rich and the poor and the strong and the weak. The holder of a right has redress, and the grievance of an injured party will be answered.” In appealing to residents and new recruits, ISIS touched upon something familiar: the desire for justice, equality, and law and order in a world that has manifestly failed to deliver any. Women, too, found opportunities under ISIS. In Fallujah, they used the regime’s justice system to secure divorces, which had been more difficult under the Iraqi government.

civilians were likely to stay in ISIS-controlled territory because, among various reasons, the “quality of governance,” including “availability of electricity, cleanliness of streets, and crime rates,” was better compared to services provided by the Iraqi government

“All the locals here wonder why the U.S. coalition never came to rescue them from Assad’s machine guns, but run to fight ISIS when it took a few pieces of land,” one rebel told the Guardian. 

the current global order has left many people behind

decades of imperialism, like the U.S. invasion of Iraq, and Russia and Iran’s interventions, have irrevocably transformed communities in the Middle East. Similarly, though ISIS opposes the Saudi government, the Salafi-Jihadi underpinnings of the group could not have gained traction without the Kingdom’s years of effort of exporting and standardizing a particular form of Islam across the Middle East. 

devoid of any political context, terms like “radicalization” and “ideology” lose meaning

how ISIS appeared in the public imagination: as a movement beyond human understanding. The only sensible answer to so inscrutable and atavistic an adversary was total war.

This frenzied interest in the U.S.’s darkly powerful new enemy lured some journalists and analysts to focus on the group full-time. It emerged as a distinct topic from the Syrian civil war, whose crowded theater was becoming difficult to explain, or the Iraq War, now a nearly-adolescent 11 years old. Soon, writers covering ISIS, what Wired called “the world’s most important beat,” developed a signature flourish, describing it not just as a terrorist organization, but as an almost supernatural threat. “It is not clear,” argued a New York Review of Books piece in 2015, “whether our culture can ever develop sufficient knowledge, rigor, imagination, and humility to grasp the phenomenon of ISIS. But for now, we should admit that we are not only horrified but baffled.”

Stories of the group’s atrocities emerged in quick succession, echoing the parade of violence ISIS was proudly broadcasting on its own channels: public executions, conscription of child soldiers, disappearances and murders of thousands, Yazidi girls sold into slavery.

by narrowly focusing on the savagery of ISIS fighters, we miss the deeper and more important story of how ISIS grew into a political force, and of how it moved not just the hearts and minds, but the physical bodies, of tens of thousands

the core issue with Caliphate isn’t just that a lying source may have misled overeager journalists. Rather, the controversy, and indeed even the proposition that a “terrorism editor” would have resolved the problem, points to a deeper flaw in the way media has long covered extremism: divorced from the local and historical contexts that have fueled its rise

After a decade of the War on Terror and chaos in the Middle East, ISIS seemed to be the ultimate testament to an enduring clash of civilizations. It is not that surprising that ISIS itself encouraged this fantastical narrative — but it is striking that our media took their word for it.

a wide array of initiatives have emerged as a direct response to China’s Belt and Road to undermine and dilute China’s infrastructural prowess: the U.S. International Finance and Development Corporation, the EU’s “Asia Connectivity Initiative,” the EU-Japan “Partnership on Sustainable Connectivity and Quality Infrastructure,” the U.S.-Japan-Australia “Blue Dot Network,” the India-Japan “connectivity corridors” and myriad other coalitions. None of these existed even three years ago. Roads have always been the pathways of conquest; now they are the battlefield of competitive connectivity. 

A repeat of the Cold War would surely not play out as favorably for the U.S. as the last one. America is politically polarized and is the world’s largest debtor nation. Its most recent major wars have been disasters and its military needs time to rebuild and adjust to new adversaries and tactics. And many of its erstwhile allies from Europe to Asia are far more vested in China than America is and don’t trust it to lead a consensus-based global coalition.

Bogging down the adversary while moving stealthily towards one’s objective has been an axiom of Chinese diplomacy for generations. But there is little stealth anymore in China’s land grabs, island-building and wolf-warrior diplomacy

With China’s suppression of information about the coronavirus painting it into a corner, Beijing no longer feels it has anything to lose and is going for broke: moving on Taiwan, Hong Kong, the Senkaku Islands, India’s borders and other disputes while the rest of the world is off-kilter, girding itself for a new Cold War with America. China’s leadership has convinced itself that West-leaning powers seek to encircle it militarily, splinter it internally and destabilize the Communist Party. This is the classical psychological spiral at the heart of any security dilemma in which each action taken by one side elevates the perceived insecurity of the other. 

in dozens of visits to Beijing, I have found my interlocutors unable to grasp this basic psychological fact. While many societies admire China’s success and are grateful for China’s role in their development, none want to be like China, nor be subservient to it. It’s an argument that’s fallen on deaf ears in Washington, too. And as with America’s experience of benevolent nation-building, China’s policy of intimidating neighbors into feebly muting their own interests has predictably backfired

American strategists have been far more fixated on China’s presence in Africa and South America rather than developing a comprehensive strategy for reassuring China’s neighbors and supporting their own efforts to stand up to it.

What the U.S. and Europe do have in their favor is that they are territorially secure while China is not. China has 14 neighbors, all of which harbor deep suspicions of its motives even as many (especially Russia) cooperate with it.

Despite the immense economic leverage China has accrued vis-a-vis the many states along its perimeter, it is the complexity of having so many neighbors that constrains China more than its increasingly sophisticated military arsenal suggests. Maintaining global influence is much harder when you are fighting a 14-front war in your own neighborhood. 

From Malabar to Pearl Harbor, the U.S., Japan, Australia, India and numerous other countries have been deepening their coordination in the Indo-Pacific maritime domain. The “quad” coalition features joint strategic patrols and hardware support for the navies of Vietnam, the Philippines and Indonesia in the South China Sea. This summer, ASEAN foreign ministers finally graduated from their usually limp communiques watered down by Chinese pressure and reaffirmed that the U.N. Convention on the Law of the Sea must be the basis for arbitrating maritime disputes. 

Boundary agreements are rarely perceived as fair by both sides, yet such settlements have the virtue of enabling counties to mature towards functional cooperation.  

Precisely because the U.S. and EU have imposed such stiff restrictions on Chinese investment, China has redirected its outbound capital portfolio ever more towards its more proximate Asian domain. And in the wake of the COVID-19 crisis, once fast-growing countries face capital outflows and weak global demand amid ruptured supply chains. The West may be squeezing China out of some markets, but China’s balloon is inflating across Asia as it lowers tariffs on all its Belt and Road trading partners

Laos and Cambodia, two of Asia’s poorest countries, have become all but wholly owned subsidiaries of China, even as China’s Mekong River dams have ravaged their agriculture through volatile water flows and chemical pesticides. With stronger technical and diplomatic assistance, these countries could demand that Chinese investments reinforce their sustainability and local businesses. 

It was always going to be an uphill battle for China to be perceived as a benevolent superpower. Unlike America or the European Union, China is wholly unconvincing as a multiethnic empire. It systematically squelches diverse identities rather than elevating them. Furthermore, though China is an ancient and rich civilization, it coexists with other Asian civilizations with equally respectable glory. None will ever bow to the others, as Japan learned the hard way in the 20th century. Every time China gains an inch of territory, it loses a yard of credibility. The essence of geopolitical stability is equilibrium, and the pathway to it follows the logic of reciprocity. 

China’s assertiveness signals neither an inevitable new Cold War nor a new unipolar hegemony. Rather, it is one phase in Asia’s collective story and the global shift towards multipolarity.

Never has Eurasia been ruled by a single hegemon. The Mongols came closest 700 years ago, but the 14th-century Black Death fractured its disparate khanates, and the Silk Road fell idle. Today again, a pandemic has emerged from China, but rather than shut down the Silk Road, we should build many more of them among dozens of Eurasian nations rather than in and out of China alone. All roads need not lead to Beijing.

Our analysis confirms that unequal exchange is a significant driver of global inequality, uneven development, and ecological breakdown.

Today, we are told, the world economy functions as a meritocracy: countries that have strong institutions, good markets, and a steadfast work ethic become rich and successful, while countries that lack these things, or which are hobbled by corruption and bad governance, remain poor. This assumption underpins dominant perspectives in the field of international development (Sachs, 2005, Collier, 2007, Rostow, 1990, Moyo, 2010, Calderisi, 2007, Acemoglu and Robinson, 2012), and is reinforced by the rhetoric, common among neoclassical economists, that free-trade globalization has created an “even playing field”.

Emmanuel and Amin argued that unequal exchange enables a “hidden transfer of value” from the global South to the global North, or from periphery to core, which takes place subtly and almost invisibly, without the overt coercion of the colonial apparatus and therefore without provoking moral outrage. Prices are naturalized on the grounds that they represent “utility”, or “value”, or the outcome of “market mechanisms” such as supply and demand, obscuring the extent to which they are determined by power imbalances in the global political economy. Price differentials in international trade therefore function as an effective method of maintaining the patterns of appropriation that once overtly defined the colonial economy, allowing blame for “underdevelopment” to be shifted onto the victims.

Historians have demonstrated that the rise of Western Europe depended in large part on natural resources and labour forcibly appropriated from the global South during the colonial period, on a vast scale. Spain extracted gold and silver from the Andes, Portugal extracted sugar from Brazil, France extracted fossil fuels, minerals and agricultural products from West Africa, Belgium extracted rubber from the Congo; and Britain extracted cotton, opium, grain, timber, tea and countless other commodities from its colonies around the world – all of which entailed the exploitation of Southern labour on coercive terms, including through mass enslavement and indenture. This pattern of appropriation was central to Europe’s industrial growth, and to financing the expansion and industrialization of European settler colonies, including Canada, Australia, New Zealand and the United States, which went on to develop similarly imperialist orientations toward the South (e.g., Naoroji, 1902, Pomeranz, 2000, Beckert, 2015, Moore, 2015, Bhambra, 2017, Patnaik, 2018, Davis, 2002).

for every unit of embodied resources and labour that the South imports from the North they have to export many more units to pay for it, enabling the North to achieve a net appropriation through trade. This dynamic was theorized by Emmanuel (1972) and Amin (1978) as a process of “unequal exchange”.Emmanuel and Amin argued that unequal exchange enables a “hidden transfer of value” from the global South to the global North, or from periphery to core, which takes place subtly and almost invisibly, without the overt coercion of the colonial apparatus and therefore without provoking moral outrage.

Following Dorninger et al. (2021), we use a “footprint” analysis of input–output data to quantify the physical scale of raw materials, land, energy and labour embodied in trade between the North and South, looking not only at traded goods themselves but also the upstream resources and labour that go into producing and transporting those goods, including the machines, factories, infrastructure, etc.

Grounding our analysis in the physical dimensions of unequal exchange is important for several reasons. First, these resources – raw materials, land, labour and energy – embody the productive potential that is required for meeting human needs (use-value) and for generating economic growth (exchange-value). Physical drain is therefore ultimately what drives global inequalities in terms of access to provisions, as well as in terms of GDP or income (see Hornborg, 2020). Second, this approach allows us to maintain sight of the ecological impacts of unequal exchange. We know that excess energy and material consumption in high-income nations, facilitated by appropriation from the rest of the world, is causing ecological breakdown on a global scale. Tracing flows of resources embodied in trade allows us to determine the extent to which Northern appropriation is responsible for ecological impacts in the South; i.e., ecological debt (Roberts and Parks, 2009, Warlenius et al., 2015, Hornborg and Martinez-Alier, 2016).

Due to the growing fragmentation of international commodity chains, monetary databases on bilateral gross trade flows have been criticised for not accurately depicting the monetary interdependencies between national economies (Johnson and Noguera, 2012), i.e., the amount of a countries’ value added that is induced by foreign final demand and international trade relations. Trade in Value Added (TiVA) indicators Johnson and Noguera, 2012, Timmer et al., 2014 are designed to take into account the complexity of the global economy. The TiVA concept is motivated by the fact that, in monetary terms, trade in intermediates accounts for approximately two-thirds of international trade. Imports (of intermediates) are used to produce exports and hence bilateral gross exports may include inputs (i.e., value added) from third party countries (Stehrer, 2012). TiVA reveals where (e.g., in which country or industry) and how (e.g. by capital or labour) value is added or captured in global commodity chains (Timmer et al., 2014).

TiVA, which is sometimes referred to as the “value footprint”, is the monetary counterpart of the MRIO-based environmental footprint because both indicators follow the same system boundaries, i.e., all supply chains between production and final consumption of two countries including all direct and indirect interlinkages. Moreover, in contrast to global bilateral monetary trade flows, TiVA is globally balanced, meaning that national exports and imports globally sum up to zero. This is an important feature of the TiVA indicator that facilitates more consistent and unambiguous assessments.

for every unit of embodied raw material equivalent that the South imports from the North, they have to export on average five units to “pay” for it

For land the average ratio is also 5:1, for energy it is 3:1, and for labour it is 13:1

in the year 2015 the North’s net appropriation from the South totalled 12 billion tons of raw materials, 822 million hectares of land, 21 exajoules of energy (equivalent to 3.4 billion barrels of oil), and 188 million person-years equivalents of labour (equivalent to 392 billion hours of work). By net appropriation we mean that these resources are not compensated in equivalent terms through trade; they are effectively transferred gratis. And this appropriation is not insignificant in scale; on the contrary, it comprises a large share (on average about a quarter) of the North’s total consumption.

significant consequences for the global South, in terms of lost use-value. This quantity of Southern raw materials, land, energy and labour could be used to provision for human needs and develop sovereign industrial capacity in the South, but instead it is mobilized around servicing consumption in the global North.

Eight hundred and twenty-two million hectares of land, which is twice the size of India, would in theory be enough to provide nutritious food for up to 6 billion people, depending on land productivity and diet composition

material use is tightly linked to environmental pressures. It accounts for more than 90% of variation in environmental damage indicators (Steinmann et al., 2017), and more than 90% of biodiversity loss and water stress (International Resource Panel, 2019). Moreover, as Van der Voet et al. (2004) demonstrate, while impacts vary by material, and vary as technologies change, there is a coupling between aggregate mass flows and ecological impact. Net flows of material resources from South to North mean that much of the impact of material consumption in the North (43% of it, net of trade) is suffered in the South. The damage is offshored.

Industrial ecologists hold that global extraction and use of materials should not exceed 50 billion tons per year (Bringezu, 2015). In 2015, the global economy was using 87 billion tons per year, overshooting the boundary by 74% and driving ecological breakdown. This overshoot is due almost entirely to excess resource consumption in global North countries. The North consumed 26.71 tons of materials per capita in 2015, which is roughly four times over the sustainable threshold (6.80 tons per capita in 2015). Our results indicate that most of the North’s excess consumption (58% of it) is sustained by net appropriation from the global South; without this appropriation, material use in high-income nations would be much closer to the sustainable level.

In consumption-based terms, the North is responsible for 92% of carbon dioxide emissions in excess of the planetary boundary (350 ppm atmospheric concentration of CO2) (Hickel, 2020), while the consequences harm the South disproportionately, inflicting dramatic social and economic costs (Kikstra et al., 2021b, Srinivasan et al., 2008). The South suffers 82–92% of the costs of climate change, and 98–99% of the deaths associated with climate change (DARA, 2012)

Net appropriation of land means soil depletion, water depletion, and chemical runoff are offshored; net appropriation of energy means that the health impacts of particulate pollution are offshored; net appropriation of labour means that the negative social impacts of exploitation are offshored, etc (Wiedmann and Lenzen, 2018). In the case of non-renewable resources there is also a problem of depletion: resources appropriated from the South are no longer available for future generations to use (Costanza and Daly, 1992, World Bank, 2018), which is particularly problematic given that under conditions of net appropriation economic losses are not offset by investments in capital stock (cf. Hartwick, 1977). Finally, the extractivism that underpins resource appropriation generates social dislocations and conflicts at resource frontiers (Martinez-Alier, 2021).

the value of resources and labour cannot be quantified in dollars, and there is no such thing as a “correct” price.

Prices under capitalism do not reflect value or utility in any objective way. Rather, they reflect, among other things, the (im)balance of power between market agents (capital and labour, core and periphery, lead firms and their suppliers, etc); in other words, they are a political artefact

While prices by definition do not reflect value, they do allow us to compare the scale of drain to prevailing monetary representations of production and income in the world economy.

Fig. 2 shows that drain from the South in 2015 amounted to $14.1 trillion when measured in terms of raw material equivalents, $5.1 trillion when measured in terms of land, $3.6 trillion when measured in terms of energy and $20.3 trillion when measured in terms of labour.

Over the period 1990–2015, the drain sums to $242 trillion (constant 2010 USD). This represents a significant “windfall” for the North, similar to the windfall that was derived from colonial forms of appropriation; i.e., goods that did not have to be produced on the domestic landmass or with domestic labour, and did not have to be bought on the domestic market, or paid for with exports (see Pomeranz, 2000, Patnaik, 2018). While previous studies have shown that the price distortion factor increased dramatically during the structural adjustment period in the 1980’s (Hickel et al., 2021), our data confirms that since the early- to mid-1990’s it has tended to decline slightly. This means that the increase in drain during the period 1990–2007, prior to the global financial crisis, was driven primarily by an increase in the volume of international trade rather than by an increase in price distortion.

Table 3 shows that, over the 1990–2015 period, resources appropriated from the South have been worth on average roughly a quarter of Northern GDP.

the North’s reliance on appropriation from the South has generally increased over the period (despite a significant drop after the global financial crisis), whereas the South’s losses as a share of total economic activity have generally decreased, particularly since 2003, due to an increase in South-South trading and higher domestic GDP creation or capture within the South, both driven largely by China

Aid flows create the powerful impression that rich countries give benevolently to poorer countries. But the data on drain through unequal exchange raises significant questions about this narrative.

net appropriation by DAC countries through unequal exchange from 1990 to 2015 outstripped their aid disbursements over the same period by a factor of almost 80

for every dollar of aid that donors give, they appropriate resources worth 80 dollars through unequal exchange. From the perspective of aid recipients, for every dollar they receive in aid they lose resources worth 30 dollars through drain

The dominant narrative of international development holds that poor countries are poor because of their own internal failings and are therefore in need of assistance. But the empirical evidence on unequal exchange demonstrates that poor countries are poor in large part because they are exploited within the global economy and are therefore in need of justice. These results indicate that combating the deleterious effects of unequal exchange by making the global economy fairer and more equitable would be much more effective, in terms of development, than charity.

In an equitable world, the resource trade deficit that the North sustains in relation to the South would be financed with a parallel monetary trade deficit. But in reality, the monetary trade deficit is very small, equivalent to only about 1% of global trade revenues, and fluctuates between North and South. In effect, this means that the North achieves its large net appropriation of resources and labour from the South gratis.

The question of sectoral disparities has been moot since the 1980s, however, as industrial production has shifted overwhelmingly to the South. The majority of Southern exports (70%) consist of manufactured goods (data from UNCTAD; see Smith, 2016). Of all the manufactured goods that the USA imports, 60% are produced in developing countries. For Japan it is 70%. We can see this pattern reflected also in the industrial workforce. As of 2010, at least 79% of the world’s industrial workers live in the South (data from the ILO; see Smith, 2016). This shift is due in large part to the rise of global commodity chains, which now constitute 70% of international trade. Between 1995 and 2013, there has been an increase of 157 million jobs related to global commodity chains, and an estimated 116 million of them are concentrated in the South, predominantly in the export manufacturing sector (ILO, 2015). In other words, during the period we analyse in this paper (1990–2015), the South has contributed the majority of the world’s industrial production, including high-technology production such as computers and cars. And yet price inequalities remain entrenched.

if Northern states or firms leverage monopoly power within global commodity chains to depress the prices of imports and increase the prices of final products, their labour “productivity” appears to improve, and that of their counterparts declines, even if the underlying production process remains unchanged. Indeed, empirical evidence indicates that real productivity differences between workers are minimal, and cannot explain wage inequalities (Hunter et al., 1990).

wage inequalities exist not because Southern workers are less productive but because they are more intensively exploited, and often subject to rigid systems of labour control and discipline designed to maximize extraction (Suwandi et al., 2019). Indeed, this is a major reason why Northern firms offshore production to the South in the first place: because labour is cheaper per unit of physical output (Goldman, 2012).

the terminology of “value-added” is a misnomer. In international trade, TiVA does not tell us who adds more value but rather who has more power to command prices. And in the case of global commodity chains, TiVA does not indicate where value is produced but rather where it is captured (Smith, 2016).

our analysis reveals that value in global commodity chains is disproportionately produced by the South, but disproportionately captured by the North (as GDP). Value captured in this manner is misleadingly attributed to Northern economic activities

rich countries are able to maintain price inequalities simply by virtue of being rich. This finding supports longstanding claims by political economists that, all else being equal, price inequalities are an artefact of power. Just as in a national economy wage rates are an artefact of the relative bargaining power of labour vis-à-vis capital, so too in international trade prices are an artefact of the relative bargaining power of national economies and corporate actors vis-à-vis their trading partners and suppliers. Countries that grew rich during the colonial period are now able to leverage their economic dominance to depress the costs of labour and resources extracted from the South. In other words, the North “finances” net appropriation from the South not with money, but rather by maintaining the prices of Southern resources and labour below the global average level.

Patents play a key role here: 97% of all patents are held by corporations in high-income countries (Chang, 2008:141)

In some cases, patents involve forcing people in the South to pay for access to resources they might otherwise have obtained much more affordably, or even for free (Shiva, 2001, Shiva, 2016).

In the World Bank and the IMF, Northern states hold a majority of votes (and the US holds a veto), thus giving them control over key economic policy decisions. In the World Trade Organization (which controls tariffs, subsidies, and patents), bargaining power is determined by market size, enabling high-income nations to set trade rules in their own interests.

ubsidized agricultural exports from the North undermine subsistence economies in the South and contribute to dispossession and unemployment, placing downward pressure on wages. Militarized borders preclude easy migration from South to North, thus preventing wage convergence. Moreover, structural adjustment programs (SAPs) imposed by the World Bank and IMF since the 1980s have cut public sector salaries and employment, rolled back labour rights, curtailed unions, and gutted environmental regulations (Khor, 1995, Petras and Veltmeyer, 2002).

SAPs, bilateral free trade agreements, and the World Trade Organization have forced global South governments to remove tariffs, subsidies and other protections for infant industries. This prevents governments from attempting import substitution, which would improve their export prices and drive Northern prices down. Tax evasion and illicit financial flows out of the South (which total more than $1 trillion per year) drain resources that might otherwise be reinvested domestically, or which governments might otherwise use to build national industries. This problem is compounded by external debt service obligations, which drain government revenue and require obeisance to economic policies dictated by creditors (Hickel, 2017). In addition, structural dependence on foreign investors and access to Northern markets forces Southern governments and firms to compete with one another by cutting wages and resource prices in a race to the bottom.

structural power imbalances in the world economy ensure that labour and resources in the South remain cheap and accessible to international capital, while Northern exports enjoy comparatively higher prices

Cheap labour and raw materials in the global South are not “naturally” cheap, as if their cheapness was written in the stars. They are actively cheapened

the analysis obscures class and geographic inequalities within countries and regions, which are significant when it comes to labour prices as well as resource consumption. The high levels of resource consumption that characterize Northern economies are driven disproportionately by rich individuals and affluent areas, as well as by corporations that control supply chains, and enabled by internal patterns of exploitation and unequal exchange in addition to drain through trade (Harvey, 2005). For example, there are marginalized regions of the United States that serve as an “internal periphery” (Wishart, 2014). It would also be useful to explore the gender dynamics of unequal exchange within countries. These questions cannot be answered with our data, however.

This research confirms that the “advanced economies” of the global North rely on a large net appropriation of resources and labour from the global South, extracted through induced price differentials in international trade. By combining insights from the classical literature on unequal exchange with contemporary insights about global commodity chains and new methods for quantifying the physical scale of embodied resource transfers, we are able to develop a novel approach to estimating the scale and value of resource drain from the global South. Our results show that, when measured in Northern prices, the drain amounted to $10.8 trillion in 2015, and $242 trillion over the period from 1990 to 2015 – a significant windfall for the North, equivalent to a quarter of Northern GDP. Meanwhile, the South’s losses through unequal exchange outstrip their total aid receipts over the period by a factor of 30.

support contemporary demands for reparations for ecological debt, as articulated by environmental justice movements and by the G77

True repair requires permanently ending the unequal distribution of environmental goods and burdens between the global North and global South, restoring damaged ecosystems, and shifting to a regenerative economic system.

It is clear that official development assistance is not a meaningful solution to global poverty and inequality; nor is the claim that global South countries need more economic liberalisation and export-oriented market integration. The core problem is that low- and middle-income countries are integrated into the global economy on fundamentally unequal terms. Rectifying this problem is critical to ensuring that global South countries have the financial, physical and human resources they need to improve social outcomes.

democratize the institutions of global economic governance, such as the World Bank, IMF and WTO, so that global South countries have more control over trade and finance policy.

end the North’s use of unfair subsidies for agricultural exports, and remove structural adjustment conditions on international finance, which would help mitigate downward pressure on wages and resource prices in the South while at the same time enabling Southern countries to build sovereign industrial capacity

a global living wage system, and a global system of environmental regulations, would effectively put a floor on labour and resource prices

Reducing North-South price differentials would in turn reduce the scale of the North’s net resource appropriation from the South (in other words, it would reduce ecologically unequal exchange), thus reducing excess consumption in the North and the ecological impacts that it inflicts on the South.

Structural transformation will only be achieved through political struggle from below, including by the anti-colonial and environmental justice movements that continue to fight against imperialism today

“Things like climate change, earthquakes, drought — they are of course realities of our lives,” Durusu-Tanrıöver said. “But there are human actions that can be taken to foresee what will happen and behave accordingly.

In the half-century leading up to empire’s collapse, the scientists found, the rings inside the tree trunks gradually start to get narrower — suggesting that water shortages were limiting the junipers’ growth. Chemical analyses of the kind of carbon captured in the wood also showed how drought altered the trees at the cellular level.

cuneiform tablets from that time in which Hittite officials fretted over rising food prices and asked for grain to be sent to their cities. But Manning said the empire — which was known for its elaborate water infrastructure projects and massive grain silos in major cities — should have been able to survive this “low frequency” drought.

between 1198 and 1196 B.C., the region was struck by three of the driest years in the entire 1,000-year-long tree ring record. The abrupt spurt of intensely dry weather may have been more than the Hittites could bear. Within a generation, the empire had dissolved.

“Very few societies ever plan for more than one or two disasters happening consecutively.”

“But I think it’s naive to believe that three years of drought would bring down the storerooms of the Hittite empire,” Weiss said. He argues that the longer-term drying trend, which has been documented in other studies, was probably more significant.

“What’s a crisis for some becomes almost an opportunity for others,” Manning said. “You have adaptation and resilience in the form of new states and new economies emerging.”

Durusu-Tanrıöver blames an unsustainable economy and centralized political system. The intensive agricultural practices required to support the capital city probably exhausted the region’s water resources and weakened surrounding ecosystems
