The Swedish furniture maker IKEA has designed a refugee shelter capable of housing one family. The structures are designed for assembly without tools and are transportable in a flat pack. The shelter uses technology that keeps the building cool during the day and warm at night, with a solar panel providing electricity. The units are being tested in a refugee camp in southeastern Ethiopia where there are about 190,000 Somali refugees, as well as in Iraq and Lebanon. When mass-produced, the structure will cost slightly more than a tent but will be more durable. It is estimated that 3.5 million refugees currently live in tents (Christian Science Monitor, June 19).
