With up to four million of its citizens living as refugees in neighbouring countries soon after the 1994 genocide, the government of Rwanda has introduced a low-cost housing scheme, known locally as "Imidugudu", to resettle thousands of people who returned after the killings. So far, the government has constructed at least 300,000 of these mud-bricked homes under the Imidigudu initiative, although it is still grappling with the impact of the genocide on human settlement.
