From The Guardian: Thousands of Central American migrants trudging through Mexico towards the US have regularly been described as either fleeing gang violence or extreme poverty. But another crucial driving factor behind the migrant caravan has been harder to grasp: climate change, even if migrants don’t often specifically mention “climate change” as a motivating factor.
While violence and poverty have been cited as the reasons for the exodus, experts say the big picture is that changing climate is forcing farmers off their land – and it’s likely to get worse
Thousands of Central American migrants trudging through Mexico towards the US have regularly been described as either fleeing gang violence or extreme poverty.
But another crucial driving factor behind the migrant caravan has been harder to grasp: climate change.
Most members of the migrant caravans come from Guatemala, Honduras and El Salvador – three countries devastated by violence, organised crime and systemic corruption, the roots of which can be traced back to the region’s cold war conflicts.
Experts say that alongside those factors, climate change in the region is exacerbating – and sometimes causing – a miasma of other problems including crop failures and poverty.
And they warn that in the coming decades, it is likely to push millions more people north towards the US.
“The focus on violence is eclipsing the big picture – which is that people are saying they are moving because of some version of food insecurity,” said Robert Albro, a researcher at the Center for Latin American and Latino Studies at American University.
“The main reason people are moving is because they don’t have anything to eat. This has a strong link to climate change – we are seeing tremendous climate instability that is radically changing food security in the region.”
Migrants don’t often specifically mention “climate change” as a motivating factor for leaving because the concept is so abstract and long-term, Albro said. But people in the region who depend on small farms are painfully aware of changes to weather patterns that can ruin crops and decimate incomes.
Pausing for a rest as the first of the three recent migrant caravans passed through the Mexican town of Huixtla last week, Jesús Canan described how he used to sow maize and beans on a hectare of land near the ancient Copán ruins in western Honduras.
An indigenous Ch’orti’ Maya, Canan abandoned his lands this year after repeated crop failures – which he attributed to drought and changing weather patterns.
“It didn’t rain this year. Last year it didn’t rain,” he said softly. “My maize field didn’t produce a thing. With my expenses, everything we invested, we didn’t have any earnings. There was no harvest.”
Desperate and dreaming of the United States, Canan hit the road in early October and joined the migrant caravan. He left behind a wife and three children – ages 16, 14 and 11 – who were forced to abandon school because Canan couldn’t afford to pay for their supplies.
“It wasn’t the same before. This is forcing us to emigrate,” he said. “In past years, it rained on time. My plants produced, but there’s no longer any pattern [to the weather].”
US Customs and Border Patrol data shows a surge in outward migration from
western Honduras, a prime coffee-producing area, said Stephanie Leutert, an expert in Central American migration and security at the University of Texas.
Many of those are farmers or agricultural workers who take to the road when coffee-growing is no longer profitable – such as Antonio Lara, 25, from the Honduran city of Ocotepeque, who joined the caravan with his wife and children, aged six and 18 months.
“Coffee used to be worth something, but it’s been seven years since there was a decent price,” he said.
Lara said he thought that changing weather patterns had a lot to do with the problem, though he also blamed his plight on greedy bosses and coffee dealers. “I didn’t leave my country because I wanted to. I left because I had to,” he said.
A third of all employment in Central America is linked to agriculture, so any disruption to farming practices can have devastating consequences.
Since around 2012, coffee plants across Central America have been ravaged by an epidemic called leaf rust, which according to some estimates has affected 70% of farms.
Normally, the fungus dies when temperatures drop in the evening but warmer nights are allowing it to thrive, said Sam Dupre, a researcher at the University of Maryland Baltimore County.
The impact of climate change on the fungus remains in debate, but Dupre said the situation in Guatemala “shows even without a direct climate change link what happens when these global commodities fail”.
“One of the things I found was that people, largely because they weren’t able to pay their debts, to get money for food, they started to migrate,” Dupre said. “People were telling me before the coffee leaf rust hit, we didn’t migrate. Now we do. It’s normal.”
A study of Central American migrants by the World Food Program last year found that nearly half described themselves as food insecure. The research found an increasing trend of young people moving as a result of knock-on poverty and lack of work.
