在亚马逊盆地的大部分地区，大约70%的人口生活在城市地区，向城市迁移的人口仍在继续。基于对亚马逊河流域两个长期定居地区十多年来收集的数据，我们发现该地区的城乡迁移是一个延伸而复杂的过程。像世界各地最近的城乡移徙者一样，亚马逊地区的移徙者虽然可能被算作城市居民，但他们往往不是离开农村地区，而是仍然是多址家庭的成员，继续参与城乡网络和农村土地使用决策。我们的研究表明，尽管这些移民普遍贫困，但他们对城市食品和建筑材料市场都产生了影响。我们提出了两个案例：亚马逊河口的巴西莓棕榈果实和秘鲁亚马逊的廉价建筑木材。我们发现，许多新的亚马逊城乡移民在消费和知识方面都保持了一些重要的农村模式。通过他们的消费行为，他们正在影响森林的面积；在讨论的两个洪泛区，树木覆盖正在增加。我们还发现森林组成的变化，反映了城市农村消费模式的持续存在，导致对巴西莓和廉价木材品种的需求和生产增加。
In much of the Amazon Basin, approximately 70% of the population lives in urban areas and urbanward migration continues. Based on data collected over more than a decade in two long-settled regions of Amazonia, we find that rural-urban migration in the region is an extended and complex process. Like recent rural-urban migrants worldwide, Amazonian migrants, although they may be counted as urban residents, are often not absent from rural areas but remain members of multi-sited households and continue to participate in rural-urban networks and in rural land-use decisions. Our research indicates that, despite their general poverty, these migrants have affected urban markets for both food and construction materials. We present two cases: that of acai palm fruit in the estuary of the Amazon and of cheap construction timbers in the Peruvian Amazon. We find that many new Amazonian rural-urban migrants have maintained some important rural patterns of both consumption and knowledge. Through their consumer behavior, they are affecting the areal extent of forests; in the two floodplain regions discussed, tree cover is increasing. We also find changes in forest composition, reflecting the persistence of rural consumption patterns in cities resulting in increased demand for and production of acai and cheap timber species.
