Wasteland
From The Vault
"The desert was looking deserted and alone. But it was kinda hard to put another one next to it." - Kamagurka
The Wasteland or Wastes basically describes the majority of the globe in the Fallout universe. After the bombs fell, the majority of native plant and animal life was destroyed creating a vast, arid emptiness. Along with the ecological damage, all human structures were partially to fully destroyed. When the survivors emerged from their shelter, they saw this desolation and aptly named it "the Wastes".
Wasteland can also refer to Fallout's predecessor Wasteland.
