The overpopulated, Israel-sized Ferghana Valley has attracted the armies of Alexander the Great, Arabs, Mongols and Russian tsars. It has also spawned some of the bloodiest conflicts in the former Soviet Union, including ethnic clashes, incursions of armed Islamists and the Uzbek government's merciless crackdown on a 2005 popular revolt.
The glaciers and snows of the Tian Shan mountains around the valley give birth to the Syr Darya, one of Central Asia's two major rivers, and turn the valley into a giant hothouse with nearly perfect conditions for farming. Border areas in nearby Xinjiang, China's troubled Muslim region, also depend on Tian Shan's glaciers for water.
But between 1961 and 2012, the sky-scraping range whose name means "Heavenly Mountains" in Chinese, has lost 27 percent of its ice mass, the German Research Centre for Geosciences said last year. The annual loss amounts to up to 5.4 cubic kilometres of water a year, it said.

Are 'Water Wars' imminent in Central Asia? - Al Jazeera English - 1 views
-
farmers here are "ready to kill each other for water," a local mirob, or community official responsible for distribution of piped water from a communal canal, told Al Jazeera. The official, who could not give his name because of his job's sensitivity, described how over the past decade farmers have increasingly resorted to quarrels and fistfights and used their connections to officials to influence the timing and duration of water allocation to their land lots. This year, there's next to nothing to irrigate the fields with. "There's been no winter this year, so we're begging God for water," farmer Rasul Azamatov told Al Jazeera
-
The Ferghana valley is a bit bigger than Israel, but lacks its proficiency in water conservation - and does not have many alternatives to farming. Cheap Chinese exports have killed local plants and factories, and the valley has become a major source of labour migration - mostly to Russia.

"The root of the problem is the disintegration of the resource-sharing system the Soviet Union imposed on the region until its collapse in 1991," the International Crisis Group, a conflict studies think-tank, said in a 2014 report entitled Water Pressures in Central Asia.
-
These days, Kyrgyzstan is withholding water in massive upstream reservoirs releasing it according to electricity generation needs - that is in winter - and not the interests of now-foreign farmers next door.
-
Unsurprisingly, the word "war" resurfaced when Moscow threw its weight and money to revive Soviet-era designs to build five more dams and hydropower stations in Kyrgyzstan. The Kremlin pledged to finance the $3.2bn project on the Naryn River, Syr Darya's tributary, as part of its political effort to restore its foothold in Central Asia. Uzbek President Islam Karimov wasn't very subtle with his warning. "Control over water resources in the republics of Central Asia may lead to a full-scale war," he said in October.
-
The Ferghana Valley's problems are replicated throughout Central Asia, a landlocked region of more than 60 million people where conditions for farming are far less favourable, but tens of millions still live off land. Their problems are exacerbated by desertification, old and decrepit infrastructure and poor water management.
-
Aral is now reduced to two smaller lakes, while most of its former seabed has turned into a desert that releases tens of thousands of tons of toxic salt-dust annually.
-
In southeastern Kazakhstan, another major body of water faces Aral's fate. The shallow, boomerang-shaped Balkhash is the world's 15th largest freshwater lake mostly fed by the Ili River that flows from China. The lake that supplies three Kazakh regions with is shrinking as China amasses Ili's waters in a dozen reservoirs. Given the Gordian knot of regional problems, some experts think that in the coming decades, an armed conflict in the region over water seems inevitable.

The lavishly titled Grand Ethiopian Renaissance Dam (GERD), under construction on the Blue Nile since 2011, will be the largest in Africa when it is completed. But in Cairo it is being watched anxiously: a rapid increase in demand due to population growth, severe mismanagement of resources and a lack of investment in water infrastructure have made Egypt one of the most water-stressed countries in the world, relying on the Nile for 90 percent of its fresh water.

It has been calculated that golf courses in the US use, on average, 130,000 gallons of water each day. Those in the kingdom and elsewhere will likely use many times that amount, as well as fertilisers, pesticides and herbicides to keep them alive.

A $30 million, high-tech agricultural facility covering 10 hectares in the desert in Tunisia’s south is scheduled to open in 2018. The facility, which is a highly sophisticated green house, will use solar energy to power its operations and seawater to irrigate crops and maintain humidity. The extracted salt from the seawater will also be sold commercially.

The odd weather phenomenon that many blame for the suffering here — the drought and sudden storm pattern known as El Niño — is expected to become more frequent as the planet warms. Many semiarid parts of Guatemala will soon be more like a desert. Rainfall is expected to decrease by 60% in some parts of the country, and the amount of water replenishing streams and keeping soil moist will drop by as much as 83%. Researchers project that by 2070, yields of some staple crops in the state where Jorge lives will decline by nearly a third.

As their land fails them, hundreds of millions of people from Central America to Sudan to the Mekong Delta will be forced to choose between flight or death. The result will almost certainly be the greatest wave of global migration the world has seen.

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.
-
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
-
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.
-
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.
-
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.
-
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.”
-
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
-
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.
-
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.)
-
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.
-
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
-
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.
-
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.
-
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.”
-
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.
-
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.
-
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

“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.”
