Imagine waking up to find that your town has become a war zone. Your neighborhood is being bombed, and it’s no longer safe to sleep in your own bed. What would your family do?
For millions of people around the world, a situation like that is a reality—and their only choice is to flee. Indeed, the United Nations (U.N.) estimates that nearly 60 million people are currently displaced worldwide, having been driven from their homes by war or persecution. Many are refugees as a result of a violent civil war that has torn apart Syria since 2011. Millions of people have also run from their homes in Somalia, Afghanistan, and other unstable countries.
Many of these displaced people end up in refugee camps in their home country or abroad. Life may be safer there, but it’s rarely easy. Nearly 3.5 million refugees live in tents; millions more live in makeshift shelters of plastic sheeting. Neither kind of shelter is likely to last for more than a year, if that.
To improve life in refugee camps, engineers have been working to design temporary houses that are safer, more comfortable, and more durable. Their mission is especially critical because the average refugee stays at a camp for 12 years.
“Refugees often don’t have permission to build anything permanent, and their home countries could be at war for years,” says Johan Karlsson, a project manager for Refugee Housing Unit (RHU), a company based in Sweden.
