Language, Coffee, and Migration on an Andean-Amazonian Frontier takes us to remote Amazonian villages, dusty frontier towns, roadside bargaining sessions, and coffee traders’ homes to offer a new view of settlement frontiers as they are negotiated in linguistic interactions and social relationships. The book brings together a fine-grained analysis of multilingualism with urgent issues in Latin America today. It is a timely on-the-ground perspective on the agricultural colonization of the Amazon, which has triggered an environmental emergency threatening the future of the planet.
