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. 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.

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

Much of the global economy is operating free of artificial enhancements. Lower-skilled workers confront bleak opportunities and intense competition, especially in the United States. Even as recent data shows middle-class Americans are finally starting to share in the gains from the recovery, incomes for many remain below where they were a decade ago

technological disruption and economic upheaval are now at work in an era of scarcity

The worst financial crisis since the Great Depression has left banks from Europe to the United States reluctant to lend. Real estate bonanzas from Spain to Southern California gave way to a disastrous wave of foreclosures, eliminating construction jobs. China’s slowdown has diminished its appetite for raw materials, sowing unemployment from the iron ore mines of Brazil to the coal pits of Indonesia.

Trade did not cause the breakdown in economic growth. Indeed, trade has helped generate what growth remains. But the pervasive stagnation has left little cover for those set back by globalization.

China’s entry into the World Trade Organization in 2001 unleashed a far larger shock, but a construction boom absorbed many laid-off workers.

“We do need to have these trade agreements,” Mr. Bown said, “but we do need to be cognizant that there are going to be losers and we need to have policies to address them.”

The rugged country of western North Carolina suffered mass unemployment as Chinese-made wooden furniture put local plants out of business. So did glassmakers in Toledo, Ohio, and auto parts manufacturers across the Midwest.

Even among those who support trade, doubts are growing about its ability to deliver on crucial promises. A 2014 Pew Research Center survey of people in 44 countries found that only 45 percent of respondents believed trade raises wages. Only 26 percent believed that trade lowers prices.

Workers employed in major export industries earn higher wages than those in domestically focused sectors.Americans saw their choice of products expand by one-third in recent decades, the Federal Reserve Bank of Dallas found. Trade is how raspberries appear on store shelves in the dead of winter.

In the fallout, the United States maintained limits on unemployment benefits, leaving American workers vulnerable to plummeting fortunes. Social welfare systems have limited the toll in Europe, but economic growth has been weak, so jobs are scarce.

automation has grown in sophistication and reach. Between 2000 and 2010, the United States lost some 5.6 million manufacturing jobs, by the government’s calculation. Only 13 percent of those job losses can be explained by trade, according to an analysis by the Center for Business and Economic Research at Ball State University in Indiana. The rest were casualties of automation or the result of tweaks to factory operations that enabled more production with less labor.

if robots are a more significant threat to paychecks, they are also harder to blame than hordes of low-wage workers in overseas factories.“We have a public policy toward trade,” said Douglas A. Irwin, an economist at Dartmouth College. “We don’t have a public policy on automation.”

China’s relentless development was turning farmland into factories, accelerated by a landmark in the history of trade: the country’s inclusion in the World Trade Organization.The W.T.O. was born out of the General Agreement on Tariffs and Trade, a compact forged in 1947 that lowered barriers to international commerce in an effort to prevent a repeat of global hostilities.In the first four decades, tariffs on manufactured wares plunged from about 35 percent to nearly 6 percent, according to the Federal Reserve Bank of Chicago. By 2000, the volume of trade among members had swelled to 25 times that of a half-century earlier.

Mexico — home to about 123 million people — was not big enough to refashion the terms of trade. When China joined the W.T.O. in 2001, that added a country of 1.3 billion people to the global trading system

The anti-trade backlash, building for years, has become explosive because the global economy has arrived at a sobering period of reckoning. Years of investment manias and financial machinations that juiced the job market have lost potency, exposing longstanding downsides of trade that had previously been masked by illusive prosperity.

Chinese imports eliminated nearly one million American manufacturing jobs between 1999 and 2011. Add in suppliers and other related industries, and the total job losses reach 2.4 million.

Mr. Trump vows to slap punitive tariffs on Chinese goods. But that would very likely just shift production to other low-wage countries like Vietnam and Mexico. It would not turn the lights on at shuttered textile plants in the Carolinas. (Even if it did, robots would probably capture most of the jobs.)

Trade Adjustment Assistance, a government program started in 1962 and expanded significantly a dozen years later, is supposed to support workers whose jobs are casualties of overseas competition. The program pays for job training.But Mr. Simmons rolls his eyes at mention of the program. Training has almost become a joke. Skills often do not translate from old jobs to new. Many workers just draw a check while they attend training and then remain jobless.

European workers have fared better. In wealthier countries like Germany, the Netherlands, Sweden and Denmark, unemployment benefits, housing subsidies and government-provided health care are far more generous than in the United States.In the five years after a job loss, an American family of four that is eligible for housing assistance receives average benefits equal to 25 percent of the unemployed person’s previous wages, according to data from the Organization for Economic Cooperation and Development. For a similar family in the Netherlands, benefits reach 70 percent.

Yet in Europe, too, the impacts of trade have been uneven, in part because of the quirks of the European Union. Trade deals are cut by Brussels, setting the terms for the 28 member nations. Social programs are left to national governments.

The robots will win in the end, because robots never strike. Robots improve with time.

Trade deals, immigrant labor, automation: As Mr. Arkenbout sees it, these are all just instruments wielded in pursuit of the same goal — paying him less so corporations can keep more.“When they don’t need me anymore,” he said, “I’m nothing.”

“This panel report confirms what the Trump administration has been saying for four years: The WTO is completely inadequate to stop China’s harmful technology practices,” said U.S. trade representative Robert Lighthizer in a statement. He said the U.S. had presented “extensive evidence” of China’s intellectual property theft and the WTO has offered no fixes for it.

The Trump administration has justified the sanctions under Section 301 of the Trade Act of 1974, once a common tool used by the U.S. government to impose sanctions — and recently revived by Trump. The U.S. argued that China’s actions had amounted to “state-sanctioned theft” and “misappropriation” of U.S. technology, intellectual property and commercial secrets.

The WTO panel ruled that the U.S. measures violated longstanding international trade rules because they only applied to products from China, and that Washington had not adequately substantiated its claim that the Chinese products hit with the extra duties had benefited from the allegedly unfair Chinese practices.

in the past three years, Russia has cited it in the dispute with Ukraine, Trump has used it to justify tariffs on steel, aluminium and — potentially — autos, and Bahrain, the United Arab Emirates and Saudi Arabia have cited it in a dispute with Qatar.

China may present the single most compelling factor. There is an increasing awareness that to deal with the challenge of China’s rapidly growing economy, Europe and the United States will have to learn to cooperate better

European leaders, including Prime Minister David Cameron of Britain and Chancellor Angela Merkel of Germany, have been pushing for a trade deal as a low-cost way of stimulating their struggling economies. The United States Chamber of Commerce and large companies like General Electric have also lobbied for an agreement

Potentially more important than abolishing tariffs, but also much more complicated, would be a deal that harmonized regulations on products like food, cars, toys and pharmaceuticals. Automobile manufacturers would like to see agreement on safety and emissions standards for cars, reducing or eliminating the need to build different versions for the American and European markets. Matthias Wissmann, head of the German Association of the Automotive Industry, said that harmonizing safety features would save several hundred dollars per automobile. Mr. De Gucht, who is expected to lead the talks on the European side, said that a deal could provide vital leverage over emerging powerhouses like China

The 11 remaining nations, led by Japan and Canada, finalized a revised trade pact in January. It will enter force when at least six member nations have completed domestic procedures to ratify the agreement

“We don’t get instructions from the U.S. government.” He recalled Trump’s announcement, in December, 2017, that the U.S. would recognize Jerusalem as the capital of Israel. As the United Nations considered a resolution condemning the move, Nikki Haley, Trump’s envoy to the U.N., circulated a threatening letter, saying that Trump “has requested I report back on those who voted against us.” Feeley heard nothing in advance about the letter. “Do you think we got a heads-up, to prepare?” he said. “Nothing.” Soon afterward, he received outraged telephone calls from Panama’s President and Vice-President, Isabel de Saint Malo. Feeley recalled that when Saint Malo called “she said, ‘John, friends don’t treat friends like this.’ All I could say was ‘I know. I’m sorry.’ We both knew it was going to hurt our personal and institutional relationship. And there was nothing we could do about it.”

Since Trump’s election, “we’ve taken a step back in tone,” Feeley said. “We tried to get Kerry to bury the Monroe Doctrine. But now, all of a sudden, it’s back.”

Early this year, during an appearance in Texas, Tillerson called the Monroe Doctrine “clearly . . . a success.” The rhetoric has had a chilling effect, Feeley said, “Latins believe that Trump and his senior officials have no real interest in the region, beyond baiting Mexico and tightening the screws on Cuba and Venezuela.”

In June, 2016, a major expansion of the canal was completed, and the first ship through was an enormous Chinese freighter, designed to fit the new dimensions. “I got a big American naval ship to park right outside the locks, where the Chinese ship would see it,” Feeley said. “And I threw our annual Embassy July 4th party on it.” He laughed at the memory, but he knew that the gesture was ultimately futile.

As the United States has retreated from Latin America, China’s influence has grown. Since 2005, banks linked to Beijing have provided more than a hundred and fifty billion dollars in loan commitments to the region—some years, more than the World Bank and the Inter-American Development Bank combined. In less than two decades, trade between China and Latin America has increased twenty-seven-fold.

The Taiwanese government furiously denounced Panama for succumbing to “checkbook diplomacy,” but Panamanian officials denied that the decision was motivated by economics. Then, last November, Varela travelled to Beijing and joined President Xi Jinping in a ceremony to celebrate their new friendship, at which he signed nineteen separate trade deals. At around the same time, the China Harbour Engineering Company began work in Panama on a hundred-and-sixty-five-million-dollar port.

Panama could well become China’s Latin-American hub; the One Belt, One Road initiative, working with Varela’s government, is planning to build a railway from Panama City to near the Costa Rican border. But, Feeley added, “the Panamanians are naïve about the Chinese.” He told me that he had worked to persuade Panama’s security ministry not to sign a communications-technology deal with the Chinese, partly out of concern that they would use the infrastructure for espionage, as they have elsewhere. The Chinese company Huawei, which has headquarters in Panama, lobbied hard “to delay, divert, and get the contract.” In the end, the work was contracted to an American firm, General Dynamics, but the negotiations were difficult.

Varela’s government has quietly leased the Chinese a huge building plot, on the strip of land that juts into the ocean at the mouth of the canal, to use as the site of a new Embassy. Sailors on every ship in the canal will see the proof of China’s rising power, as they enter a waterway that once symbolized the global influence of the United States.

As morale sank in the State Department, veteran diplomats had been leaving, in what some called “the exodus.” David Rank, the senior American diplomat in China, stepped down last June, after Trump withdrew from the Paris accord. “You have decisions that the rest of the world fundamentally disagrees with,” Rank said recently. He recalled that, on September 11, 2001, “I got a call from the Embassy of an allied country seconds after the attack. The person said, ‘Whatever you need, you can count on us.’ Now that we pulled out of Paris and Iran, swept tariffs across the world, I wonder if we’re going to get that call again.”

Feeley pointed out that leftist leaders were in retreat throughout Latin America, and that popular movements were rejecting old habits of corrupt governance. It was, he said, “the greatest opportunity to recoup the moral high ground that we have had in decades.” Instead, we were abandoning the region. “I keep waiting for a Latin leader to paraphrase Angela Merkel and say, ‘We can no longer count on the Americans to provide leadership.’ ”

Some people liken it to an own goal. I’d say it’s more like a self-inflicted Pearl Harbor

“There’s this idea that the States is just like the rest of us. That’s the saddest thing to me.”

Foreign Service officers were willing to work with the Trump Administration. “I don’t know of a single Trump supporter who is an F.S.O.,” he said. “But I also don’t know of a single F.S.O. who hopes for failure, myself included. Far from the Alex Jones caricature of a bunch of pearl-clutching, cookie-pushing effetes, we have an entire corps of people who will do everything they can to successfully implement American foreign policy, as it is determined by the national leaders—to include Mike Pompeo.” But, Feeley suggested, Pompeo would need to moderate his boss’s instincts. “I just do not believe that, with Trump’s rhetoric and a lot of his policy actions, we are going to recoup our leadership position in the world,” he said. “Because the evidence is already in, and we’re not. We’re not just walking off the field. We’re taking the ball and throwing a finger at the rest of the world.”

“Trade barriers will create extreme volatility,” warned Torero. “[They] will make the situation worse. That’s what we observe in food crises.”

problems could start to be seen within weeks and intensify over the following two months as key fruit and vegetables come into season

“Fruit and vegetables are also very labour intensive, if the labour force is threatened because people can’t move then you have a problem.”

“We need to have policies in place so the labour force can keep doing their job. Protect people too, but we need the labour force. Major countries have yet to implement these sorts of policies to ensure that food can keep moving.”

Countries such as the UK, with a sinking currency and high level of imports, are also likely to see food price rises unless the government takes action or retailers absorb some of the costs

Individuals can also play an important role, by avoiding panic buying and hoarding of food, and cutting down on food waste. Buying too much fresh farm produce that then goes off before it can be eaten will just exacerbate food supply problems, he said. “Individuals should only buy what they need to avoid food waste.”

In the UK, some farming leaders have called for a “land army” of workers to replace a shortfall of workers that could reach 80,000, according to one estimate, if the 60,000 seasonal workers recruited from abroad in normal years are prevented from coming, and if some British workers fall ill.

Andre Laperriere, executive director of Global Open Data for Agriculture and Nutrition, which provides data on food and agriculture, said the government must make plans to ensure the food supply chain functioned smoothly.“Empty shelves in supermarkets should not be much of a concern,” he said. “It is not a supply problem – it is a logistics problem. There is enough supply for all, as long as everyone stays calm and stops hoarding. We may tend to waste food if we hoard more than required, and hoarding would also artificially increase food prices because of the pressure on the supply chain.”

“The food sector comes under the critical infrastructure sector, along with healthcare and emergency services,”

The Rome Treaty, which established the EEC in 1957, was nothing short of a resurrection of the Berlin Conference's General Act, which 73 years earlier had sought to create an internationalised regime of free trade stretching across the middle of Africa. In Rome, six European countries, without the involvement of any Africans, promised each other equal access to trading and investment opportunities in what is today the territory of 21 African countries: Senegal, Mali, Guinea, Ivory Coast, Benin, Mauritania, Niger, Burkina Faso, the Republic of the Congo (Congo Brazzaville), the Central Africa Republic, Chad, Gabon, the Comoros, Madagascar, Djibouti, Togo, Cameroon, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Somalia. In fact, as noted by Hansen and Jonsson, three-quarters of the territory covered by the EEC actually lay outside continental Europe.

Senghor personified the contradictions of independence. A formidable intellect, he led his nation into the Yaounde agreement, was the foremost proponent of negritude and ruled for two decades before retiring on New Year's Eve 1980, the first African president to leave office voluntarily. He then promptly left for France, where he had been a citizen since 1932.

It was into this context that the countries of Africa were born. Congenitally misshapen, they were easy prey for Europe. The Eurafrica project was simply given a makeover as the 1963 Yaounde Convention signed between the EEC and 18 former French and Belgian colonies. Under the agreement, the Europeans allowed free access to their domestic markets to products from the African members, while the latter were, at least initially, permitted to impose restrictions on the entry of European goods into their territories in order to protect their own infant industries. Three years earlier, however, the UN Economic Commission for Africa had warned, as related by Hansen and Jonsson, that the arrangements were likely to lead to economic dependency by tempting the Africans "to prefer the short-run advantage of tariff concessions [in EEC markets] to the long-run gains of industrial development".

By 1962, an American observer in Paris, Schofield Coryell, declared that African countries remained "essentially what they were: agricultural appendages to Europe". If this sounds familiar, it is because African elites are, to borrow from Wole Soyinka, still heading to foreign capitals to loudly proclaim their tigritude, while consigning their countrymen into debt and bondage.

Although Europe was "the home of nationalism" according to Macmillan, Africans were encouraged to think of it as genuine indigenous expression. Even though the African nations espousing it were born out of the 1884 Berlin Conference and African nationalist leaders were the products of colonial schools and European universities, African nationalism was still cast as the antidote to colonialism rather than an outgrowth of it.

True decolonisation requires more than just the physical absence of the coloniser. It means deconstructing the frameworks that have been used to define the African's place for him. That is the work that remains to be done.

Patrick Gathara is a communications consultant, writer, and award-winning political cartoonist based in Nairobi.

“We want to move Africa away from this colonial economic model of perpetually being an exporter of primary commodities for processing elsewhere,”

goods traded within Africa were more processed than the raw materials exported from the continent to China, India, Europe and other major trading partners

“Policymakers have understood that, although trade on the continent is limited, this is value-added trade,” he said. “This is where the jobs are coming from, as opposed to trade with the rest of the world, which is mostly commodities.”

Jeffrey Peprah, chief executive of Volkswagen, Ghana, said he hoped eventually to export cars assembled in Accra to other west African countries.

For the agreement to work, one western diplomat said the free trade zone must benefit producers in smaller, poorer countries as well as those in more industrialised parts of the continent. Many countries saw the free trade area as a way of boosting their exports but few had embraced the corollary that they would need to import more, the diplomat said.

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.

greater awareness of the potential impact of natural as well as man-made shocks will accelerate tendencies not toward deglobalization but rather toward reglobalization: a reshuffling of supply chains and at least a partial reduction in the concentration of capacity inside China

The disruption caused by the pandemic creates an opportunity for U.S. policymakers to reassess and recalibrate their generally laissez-faire approach to globalization.

Another reason for attempting to shift existing supply chains and, in particular, for trying to preserve and expand domestic manufacturing capacity is that doing so could help boost the overall productivity, international competitiveness, and long-term growth prospects of the U.S. economy. That, in turn, would generate more of the aggregate resources necessary to sustain a protracted strategic competition with China, while at the same time enhancing the well-being of many American workers.

Even if the value-added from the final assembly of consumer goods is relatively small, from a strategic standpoint it would be preferable if the resulting gains accrued to the economies of U.S. friends and allies rather than to China. The physical relocation of some portion of existing supply chains could also help slow China’s efforts to extract sensitive technology through industrial espionage or coerced joint ventures.

Even a largely market-driven dispersion of supply chains and a lesser degree of concentration in China should help to reduce risks and increase resilience.

To the extent feasible, the United States should seek to source imports of critical goods from a trusted production network of facilities in friendly or allied countries, at least some of them located far from China.

During World War II and the opening stages of the Cold War, the federal government used the tax code in a focused fashion, extending the so-called rapid tax amortization privilege to promote expansion in sectors where resource requirement calculations revealed gaps that could stall defense mobilization. In the 1950s, federal agencies also used procurement guarantees to encourage the maintenance of capacity above anticipated market demand for certain minerals and machine tools by promising to buy a portion of the resulting output. Some of these were then placed in stockpiles for possible future use.

The U.S. government could use similar tools today if, for example, it wanted to expand the nation’s ability to manufacture personal protective equipment and ventilators, items that might be needed to combat the next pandemic.

Globalization is not an unstoppable natural force, propelled solely by technological progress and autonomous market forces; instead it is a man-made phenomenon with contours shaped by the choices of states as well as firms.

China’s emergence as an irresistibly attractive manufacturing platform was partly due to the sheer size of its working-age population and the falling costs of communication and transportation, but also due to deliberate government policies designed to aid in the acquisition of foreign intellectual property while keeping the cost of land, labor, and capital low and exchange rates favorable.

the migration of manufacturing capacity from the advanced industrial countries reflected not only the profit and loss calculations of individual companies but also the permissive policies of Western governments that concluded in effect (in the U.S. case) that what was good for Apple or 3M was good for the United States.

if it results in excessive dependence, an addiction to low costs can create serious commercial and strategic risks

There are obvious dangers here. Sharpened tools of trade and industrial policy can be abused by irresponsible leaders seeking to pander to voters and pay off supporters, or they may be captured and exploited by special interests.

the planet could see a greater temperature increase in the next 50 years than it did in the last 6,000 years combined. By 2070, the kind of extremely hot zones, like in the Sahara, that now cover less than 1% of the earth’s land surface could cover nearly a fifth of the land, potentially placing 1 of every 3 people alive outside the climate niche where humans have thrived for thousands of years. Many will dig in, suffering through heat, hunger and political chaos, but others will be forced to move on

In Southeast Asia, where increasingly unpredictable monsoon rainfall and drought have made farming more difficult, the World Bank points to more than 8 million people who have moved toward the Middle East, Europe and North America. In the African Sahel, millions of rural people have been streaming toward the coasts and the cities amid drought and widespread crop failures. Should the flight away from hot climates reach the scale that current research suggests is likely, it will amount to a vast remapping of the world’s populations.

Drought helped push many Syrians into cities before the war, worsening tensions and leading to rising discontent; crop losses led to unemployment that stoked Arab Spring uprisings in Egypt and Libya; Brexit, even, was arguably a ripple effect of the influx of migrants brought to Europe by the wars that followed. And all those effects were bound up with the movement of just 2 million people. As the mechanisms of climate migration have come into sharper focus — food scarcity, water scarcity and heat — the latent potential for large-scale movement comes to seem astronomically larger.

Northern nations can relieve pressures on the fastest-warming countries by allowing more migrants to move north across their borders, or they can seal themselves off, trapping hundreds of millions of people in places that are increasingly unlivable. The best outcome requires not only goodwill and the careful management of turbulent political forces; without preparation and planning, the sweeping scale of change could prove wildly destabilizing. The United Nations and others warn that in the worst case, the governments of the nations most affected by climate change could topple as whole regions devolve into war

To better understand the forces and scale of climate migration over a broader area, The New York Times Magazine and ProPublica joined with the Pulitzer Center in an effort to model, for the first time, how people will move across borders

Our model projects that migration will rise every year regardless of climate, but that the amount of migration increases substantially as the climate changes. In the most extreme climate scenarios, more than 30 million migrants would head toward the U.S. border over the course of the next 30 years

If governments take modest action to reduce climate emissions, about 680,000 climate migrants might move from Central America and Mexico to the United States between now and 2050. If emissions continue unabated, leading to more extreme warming, that number jumps to more than a million people. (None of these figures include undocumented immigrants, whose numbers could be twice as high.)

As with much modeling work, the point here is not to provide concrete numerical predictions so much as it is to provide glimpses into possible futures. Human movement is notoriously hard to model, and as many climate researchers have noted, it is important not to add a false precision to the political battles that inevitably surround any discussion of migration. But our model offers something far more potentially valuable to policymakers: a detailed look at the staggering human suffering that will be inflicted if countries shut their doors.

the coronavirus pandemic has offered a test run on whether humanity has the capacity to avert a predictable — and predicted — catastrophe. Some countries have fared better. But the United States has failed. The climate crisis will test the developed world again, on a larger scale, with higher stakes

Climate is rarely the main cause of migration, the studies have generally found, but it is almost always an exacerbating one.

In the case of Addis Ababa, the World Bank suggests that in the second half of the century, many of the people who fled there will be forced to move again, leaving that city as local agriculture around it dries up.

North Africa’s Sahel provides an example. In the nine countries stretching across the continent from Mauritania to Sudan, extraordinary population growth and steep environmental decline are on a collision course. Past droughts, most likely caused by climate change, have already killed more than 100,000 people there. And the region — with more than 150 million people and growing — is threatened by rapid desertification, even more severe water shortages and deforestation. Today researchers at the United Nations estimate that some 65% of farmable lands have already been degraded. “My deep fear,” said Solomon Hsiang, a climate researcher and economist at the University of California, Berkeley, is that Africa’s transition into a post-climate-change civilization “leads to a constant outpouring of people.”

The story is similar in South Asia, where nearly one-fourth of the global population lives. The World Bank projects that the region will soon have the highest prevalence of food insecurity in the world. While some 8.5 million people have fled already — resettling mostly in the Persian Gulf — 17 million to 36 million more people may soon be uprooted, the World Bank found. If past patterns are a measure, many will settle in India’s Ganges Valley; by the end of the century, heat waves and humidity will become so extreme there that people without air conditioning will simply die.

We are now learning that climate scientists have been underestimating the future displacement from rising tides by a factor of three, with the likely toll being some 150 million globally. New projections show high tides subsuming much of Vietnam by 2050 — including most of the Mekong Delta, now home to 18 million people — as well as parts of China and Thailand, most of southern Iraq and nearly all of the Nile Delta, Egypt’s breadbasket. Many coastal regions of the United States are also at risk.

rough predictions have emerged about the scale of total global climate migration — they range from 50 million to 300 million people displaced — but the global data is limited, and uncertainty remained about how to apply patterns of behavior to specific people in specific places.

Once the model was built and layered with both approaches — econometric and gravity — we looked at how people moved as global carbon concentrations increased in five different scenarios, which imagine various combinations of growth, trade and border control, among other factors. (These scenarios have become standard among climate scientists and economists in modeling different pathways of global socioeconomic development.)

every one of the scenarios it produces points to a future in which climate change, currently a subtle disrupting influence, becomes a source of major disruption, increasingly driving the displacement of vast populations.

Around 2012, a coffee blight worsened by climate change virtually wiped out El Salvador’s crop, slashing harvests by 70%. Then drought and unpredictable storms led to what a U.N.-affiliated food-security organization describes as “a progressive deterioration” of Salvadorans’ livelihoods.

climate change can act as what Defense Department officials sometimes refer to as a “threat multiplier.”

For all the ways in which human migration is hard to predict, one trend is clear: Around the world, as people run short of food and abandon farms, they gravitate toward cities, which quickly grow overcrowded. It’s in these cities, where waves of new people stretch infrastructure, resources and services to their limits, that migration researchers warn that the most severe strains on society will unfold

the World Bank has raised concerns about the mind-boggling influx of people into East African cities like Addis Ababa, in Ethiopia, where the population has doubled since 2000 and is expected to nearly double again by 2035

now a little more than half of the planet’s population lives in urban areas, but by the middle of the century, the World Bank estimates, 67% will. In just a decade, 4 out of every 10 urban residents — 2 billion people around the world — will live in slums

Migration can bring great opportunity not just to migrants but also to the places they go

High emissions, with few global policy changes and relatively open borders, will drive rural El Salvador — just like rural Guatemala — to empty out, even as its cities grow. Should the United States and other wealthy countries change the trajectory of global policy, though — by, say, investing in climate mitigation efforts at home but also hardening their borders — they would trigger a complex cascade of repercussions farther south, according to the model. Central American and Mexican cities continue to grow, albeit less quickly, but their overall wealth and development slows drastically, most likely concentrating poverty further. Far more people also remain in the countryside for lack of opportunity, becoming trapped and more desperate than ever.

By midcentury, the U.N. estimates that El Salvador — which has 6.4 million people and is the most densely populated country in Central America — will be 86% urban

Most would-be migrants don’t want to move away from home. Instead, they’ll make incremental adjustments to minimize change, first moving to a larger town or a city. It’s only when those places fail them that they tend to cross borders, taking on ever riskier journeys, in what researchers call “stepwise migration.” Leaving a village for the city is hard enough, but crossing into a foreign land — vulnerable to both its politics and its own social turmoil — is an entirely different trial.

I arrived in Tapachula five weeks after the breakout to find a city cracking in the crucible of migration. Just months earlier, passing migrants on Mexico’s southern border were offered rides and tortas and medicine from a sympathetic Mexican public. Now migrant families were being hunted down in the countryside by armed national-guard units, as if they were enemy soldiers.

Models can’t say much about the cultural strain that might result from a climate influx; there is no data on anger or prejudice. What they do say is that over the next two decades, if climate emissions continue as they are, the population in southern Mexico will grow sharply. At the same time, Mexico has its own serious climate concerns and will most likely see its own climate exodus. One in 6 Mexicans now rely on farming for their livelihood, and close to half the population lives in poverty. Studies estimate that with climate change, water availability per capita could decrease by as much as 88% in places, and crop yields in coastal regions may drop by a third. If that change does indeed push out a wave of Mexican migrants, many of them will most likely come from Chiapas.

even as 1 million or so climate migrants make it to the U.S. border, many more Central Americans will become trapped in protracted transit, unable to move forward or backward in their journey, remaining in southern Mexico and making its current stresses far worse.

Already, by late last year, the Mexican government’s ill-planned policies had begun to unravel into something more insidious: rising resentment and hate. Now that the coronavirus pandemic has effectively sealed borders, those sentiments risk bubbling over. Migrants, with nowhere to go and no shelters able to take them in, roam the streets, unable to socially distance and lacking even basic sanitation. It has angered many Mexican citizens, who have begun to describe the migrants as economic parasites and question foreign aid aimed at helping people cope with the drought in places where Jorge A. and Cortez come from.

a new Mexico-first movement, organizing thousands to march against immigrants

Trump had, as another senior government official told me, “held a gun to Mexico’s head,” demanding a crackdown at the Guatemalan border under threat of a 25% tariff on trade. Such a tax could break the back of Mexico’s economy overnight, and so López Obrador’s government immediately agreed to dispatch a new militarized force to the border.

laying blame at the feet of neoliberal economics, which he said had produced a “poverty factory” with no regional development policies to address it. It was the system — capitalism itself — that had abandoned human beings, not Mexico’s leaders. “We didn’t anticipate that the globalization of the economy, the globalization of the law … would have such a devastating effect,”

No policy, though, would be able to stop the forces — climate, increasingly, among them — that are pushing migrants from the south to breach Mexico’s borders, legally or illegally. So what happens when still more people — many millions more — float across the Suchiate River and land in Chiapas? Our model suggests that this is what is coming — that between now and 2050, nearly 9 million migrants will head for Mexico’s southern border, more than 300,000 of them because of climate change alone.

“If we are going to die anyway,” he said, “we might as well die trying to get to the United States.”

The world can now expect that with every degree of temperature increase, roughly a billion people will be pushed outside the zone in which humans have lived for thousands of years

Without a decent plan for housing, feeding and employing a growing number of climate refugees, cities on the receiving end of migration can never confidently pilot their own economic future.

The United States refused to join 164 other countries in signing a global migration treaty in 2018, the first such agreement to recognize climate as a cause of future displacement. At the same time, the U.S. is cutting off foreign aid — money for everything from water infrastructure to greenhouse agriculture — that has been proved to help starving families like Jorge A.’s in Guatemala produce food, and ultimately stay in their homes. Even those migrants who legally make their way into El Paso have been turned back, relegated to cramped and dangerous shelters in Juárez to wait for the hearings they are owed under law.

There is no more natural and fundamental adaptation to a changing climate than to migrate. It is the obvious progression the earliest Homo sapiens pursued out of Africa, and the same one the Mayans tried 1,200 years ago. As Lorenzo Guadagno at the U.N.’s International Organization for Migration told me recently, “Mobility is resilience.” Every policy choice that allows people the flexibility to decide for themselves where they live helps make them safer.

what may be the worst-case scenario: one in which America and the rest of the developed world refuse to welcome migrants but also fail to help them at home. As our model demonstrated, closing borders while stinting on development creates a somewhat counterintuitive population surge even as temperatures rise, trapping more and more people in places that are increasingly unsuited to human life

the global trend toward building walls could have a profound and lethal effect. Researchers suggest that the annual death toll, globally, from heat alone will eventually rise by 1.5 million. But in this scenario, untold more will also die from starvation, or in the conflicts that arise over tensions that food and water insecurity will bring

America’s demographic decline suggests that more immigrants would play a productive role here, but the nation would have to be willing to invest in preparing for that influx of people so that the population growth alone doesn’t overwhelm the places they move to, deepening divisions and exacerbating inequalities.

At the same time, the United States and other wealthy countries can help vulnerable people where they live, by funding development that modernizes agriculture and water infrastructure. A U.N. World Food Program effort to help farmers build irrigated greenhouses in El Salvador, for instance, has drastically reduced crop losses and improved farmers’ incomes. It can’t reverse climate change, but it can buy time.

Thus far, the United States has done very little at all. Even as the scientific consensus around climate change and climate migration builds, in some circles the topic has become taboo. This spring, after Proceedings of the National Academy of Sciences published the explosive study estimating that, barring migration, one-third of the planet’s population may eventually live outside the traditional ecological niche for civilization, Marten Scheffer, one of the study’s authors, told me that he was asked to tone down some of his conclusions through the peer-review process and that he felt pushed to “understate” the implications in order to get the research published. The result: Migration is only superficially explored in the paper.

Our modeling and the consensus of academics point to the same bottom line: If societies respond aggressively to climate change and migration and increase their resilience to it, food production will be shored up, poverty reduced and international migration slowed — factors that could help the world remain more stable and more peaceful. If leaders take fewer actions against climate change, or more punitive ones against migrants, food insecurity will deepen, as will poverty. Populations will surge, and cross-border movement will be restricted, leading to greater suffering. Whatever actions governments take next — and when they do it — makes a difference.

El Paso is also a place with oppressive heat and very little water, another front line in the climate crisis. Temperatures already top 90 degrees here for three months of the year, and by the end of the century it will be that hot one of every two days. The heat, according to researchers at the University of California, Berkeley, will drive deaths that soon outpace those from car crashes or opioid overdoses. Cooling costs — already a third of some residents’ budgets — will get pricier, and warming will drive down economic output by 8%, perhaps making El Paso just as unlivable as the places farther south.

“If we don’t develop a different attitude,” he said, “we’re going to be like people in the lifeboat, beating on those that are trying to climb in.”

issues such as securing electricity grids around the world against cyberattacks, since a decarbonized world will depend even more on electrical power as many additional sectors—such as buildings, cars, and trucks—are electrified

access to rare earths and other critical minerals such as lithium and cobalt will be even more important as raw materials for batteries, solar panels, and other renewable energy technologies.

defense leaders should work with their counterparts in other governments and within international institutions, such in the United Nations Security Council and NATO, to integrate climate change into their security agendas. Defense planning must increasingly consider the impacts of climate change, such as the threats of extreme weather to military installations, the stresses increased disaster assistance may pose to military readiness, and the risks food or water scarcity may pose to security in fragile states

From the standpoint of foreign policy, stronger domestic action can also lay the groundwork for cooperation instead of conflict with the European Union, which is planning to impose carbon border tariffs on imports from countries taking inadequate climate actions.

foreign policy must go beyond climate and energy diplomacy to make mainstream the consideration of climate change in all foreign-policy decisions. It may not always prevail when weighed against all other national security goals, but it is too important to be ignored.

the biggest shift from the current U.S. approach would be to take climate change considerations into the mainstream of all national-security and foreign-policy decision-making

Every ton of carbon dioxide contributes to climate change no matter where it is emitted, so an ambitious climate strategy cannot only be domestic—it must put the issue squarely at the center of U.S. foreign policy.

given both the urgency and global nature of climate change, the issue cannot be siloed into U.S. State Department or Energy Department offices and spheres of diplomacy. Many aspects of U.S. foreign policy will impact, and be impacted by, climate change. An effective foreign policy requires taking climate change directly into consideration—not just as a problem to resolve, but as an issue that can affect the success and failure of strategies in areas as varied as counterterrorism, migration, international economics, and maritime security.

a strategy for stability in Iraq will not be effective unless it considers the impacts of water scarcity and heat waves on the Iraqi people or the loss of Iraq’s oil revenue as climate policy gradually erodes oil demand. Similarly, the United States’ efforts to counter terrorism in North Africa may prove fruitless unless officials also consider climate impacts on desertification that make local populations vulnerable to terrorists’ promises

U.S. foreign policy has aimed for many years to rebuild Iraq’s struggling economy by helping the country to boost its oil output, and to address its chronic and politically destabilizing electricity shortages by increasing gas production as well. A climate-centered foreign policy would not only provide assistance to reduce flaring and use that gas within Iraq, but also explore opportunities to attract investment in renewable energy

in many cases there may not be a climate-friendly alternative approach. But foreign-policy makers won’t know whether the alternatives exist or not unless they ask the question

The National Environmental Policy Act requires that before major federal actions are taken, the relevant agency analyzes the effects on the environment and identifies reasonable alternatives that may mitigate those effects. A similar internal step in the foreign-policy making process—time permitting—would ensure that officials have full information about environmental consequences before they act. Several international financial institutions such as the World Bank have processes, albeit imperfect, to review the environmental impacts of their actions
