McDonald said of the novel:

The image of the unstoppable wave of transformation was nicked from The Wrath of Khan: it's the Genesis device, slowed down, and once I had that, it became a rich source of metaphors: for colonialism, new technology, globalisation, change, death. If the Chaga is colonialism, it's a unique kind that allows the people of the poor South to use and transform it to meet their needs and empower themselves: it's a symbiosis.[1]

Chaga was nominated for the British Science Fiction Association Award for Best Novel (1995),[2] and the John W. Campbell Memorial Award for Best Science Fiction Novel (1996).[3]
