This paper reviews the state of knowledge and develops a conceptual model for researching frontier migration in the developing world with a focus on Latin America. Since only a small fraction of migrants move to forest frontiers, identifying people and place characteristics associated with this phenomenon could usefully inform policies aimed at forest conservation and rural development. Yet population scholars train their efforts on urban and international migration while land use/cover change researchers pay scant attention to these migration flows which directly antecede the most salient footprint of human occupation on the earth's surface: the conversion of forest to agricultural land.
本文回顾了相关知识状况，并构建了一个概念模型，用于研究发展中世界的前沿移民问题，重点关注拉丁美洲。由于只有一小部分移民前往森林前沿地区，识别与这一现象相关的人口和地域特征，可为旨在保护森林和促进农村发展的政策提供有益参考。然而，人口学者将精力集中在城市和国际移民上，而土地利用/覆盖变化研究人员对这些直接先于人类在地球表面最显著居住足迹（即森林转变为农业用地）的移民流动关注甚少。
