摘要:This paper explores the story of settlers overcoming challenges common to the environment of expanding agricultural frontiers, and how this is refected on the land-use and livelihood choices that unfold with the aging of settlements. The study site is a land reform project in the State of Acre, Brazil. We found that most families seek to diversify their livelihood strategies and take advantage of new opportunities as a way to cope with income uncertainties largely present on the frontier setting. As in other parts of the Amazon, cattle-ranching is the single most important activity to secure income, but complementary activities such as agroforestry and fsh breeding are key for economic security and improvements. Key words: land-use, Acre, Amazonia.
