DESCRIPTION (provided by applicant): This project addresses the reciprocal relationship between population and environment in the Amazon Basin. We consider the influences of the changing demography of households on land use and the influences of the biophysical environment on the fertility and migration behaviors of household members in a spatially-explicit fashion. A number of variables have been found to mediate between population and environment, requiring detailed examination of this complex, reciprocal relationship. In this project we will survey 952 households in two adjacent study areas, Altamira and Santarem, Para State, Brazil that allows us to study not just the behavior of the first generation of settlers in the frontier (Altamira) but also second and third generation dynamics (Santarem). We make intensive use of Landsat satellite digital data time series from 1972 to the present; a GIS overlay of the property boundaries in the region that permits a one-to-one relating of households to land use changes, as well as transportation, hydrologic, and topographic information; and a georeferenced survey of the 952 households that examines land use and deforestation decisions and the demography of households. The research will address intergenerational population-and-environment dynamics, the impact of climate changes on deforestation choices, and the differences in land use and labor allocation choices made by rural and urban residents.

描述（由申请人提供）：该项目解决了亚马逊盆地中人口与环境之间的相互关系。我们认为，家庭不断变化的人口统计学对土地使用的影响以及生物物理环境的影响对家庭成员的生育和迁移行为的影响以空间解释的方式。已经发现许多变量可以在人口和环境之间进行中介，需要详细检查这种复杂的，相互的关系。在该项目中，我们将在巴西的帕拉州阿尔塔米拉和圣塔雷姆（Altamira和Santarem）中调查952个家庭，这使我们不仅可以研究边境（Altamira）第一代定居者的行为，而且还可以研究第二代和第三代动力学（Santarem）。从1972年到现在，我们大量使用Landsat卫星数字数据时间序列；该地区财产边界的GIS覆盖层，允许家庭一对一的联系发生土地利用变化，以及运输，水文和地形信息；以及对952户家庭进行地理参与的调查，该调查研究了土地使用和森林砍伐的决定以及家庭的人口统计学。这项研究将解决国际人口和环境的动态，气候变化对森林砍伐选择的影响以及农村和城市居民做出的土地使用和劳动分配选择的差异。
