New ways to curb climate migration

Many nations are building better resiliency in places vulnerable to weather disasters, a task as important as curbing carbon emissions.

Extreme weather events, many of which are rooted in climate change, could displace some 216 million people within their own countries by 2050, finds a new study from the World Bank. And that is only in poorer countries. Another study estimates that every additional day each year with an average temperature of about 90 degrees Fahrenheit adds nearly 1% to the number of climate migrants. Added to the tens of millions of people who have fled war or political strife – as witnessed in Afghanistan – solutions to forced migration are more urgent than ever.

The World Bank’s new research, titled Groundswell 2.0, offers this suggestion: If governments take quick remedial action they could cut internal migration, and the hardships it brings, by as much as 60% to 80%. The action most needed would be to reduce worldwide emissions of greenhouse gases. A United Nations Climate Change Conference of the Parties (COP26) is scheduled to be held in early November in Glasgow, Scotland, a follow-up to the Paris climate accords of 2015.

As governments struggle to pledge and keep promises to reduce emissions, the World Bank says concurrent steps can be taken to build resiliency and fend off the worst effects of climate migration. These include ways to help people stay in their homes, as well as to help in their movement to and resettlement in new locations.

In Egypt, for example, parts of the Nile delta are projected to be places of out-migration. Several cities, including Cairo, should expect to receive these refugees. The report notes that planners could identify places most likely to be hit hardest by climate change and help more climate-resilient areas prepare to take in migrants.

Many other ways to help ease climate migration are available. More drought-resistant crops, for example, are being developed that could help keep farmers home. Rooftop water harvesting can be used to irrigate fields.

In some villages in India where water harvesting and other water conservation methods are being undertaken, climate migration has been reversed and migrants are returning to their homes, says Sunita Narain, director general of the Center for Science and Environment in New Delhi, in a recent interview with The Times of India. “It is essential to invest in building local climate resilience and protecting community economies,” she added.

Ways to mitigate climate migration are becoming well known. Even as nations try to curb carbon emissions, they can also put measures in place to solve the rising displacement of people by weather disasters.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
