Tsunami Priority: Homes
"[A] surprising number of the more than 1 million people left homeless by the waves have yet to acquire a home of their own. The push for quick housing often rubbed up against the need for an agreed framework on where and how to rebuild. Housing designs were put on ice while governments set out reconstruction plans.
...The difference between temporary and permanent housing comes down to either the materials used or locations chosen, or both. Some temporary shelters are little more than tin shacks. Others use materials like bricks, concrete, and wood that could last decades. In these cases, their "temporary" designation has allowed aid groups to build close to the coast and avoid waiting on governments to sort out land title and zoning issues."
