AMAZONIAN DEFORESTATION AND THE STRUCTURE OF HOUSEHOLDS (PHASE III)

该项目致力于解决边疆地区人口与环境之间的相互关系。 通过关注社会、经济、人口和经济的相互联系的过程，巴西亚马逊 环境变化。在早期的研究中，我们研究了国内周期对土地利用和 区分了周期效应和队列效应，并发现财产周期解释了更多的 土地覆盖的动态变化比家庭周期更大，特别是在第一代之后。在这个阶段 在研究中，我们扩大了我们的重点，以解决城市社会经济一体化所发挥的作用 和农村地区，以及一个似乎正在改变面貌的外生变化的作用： 资本投资在规模化机械化农业和牧业中的作用越来越大。在前一阶段， 我们在第一个研究地点对先前调查的家庭和物业进行了跟踪调查 (阿尔塔米拉)。在这一阶段，我们将对以前接受调查的住户和 在Santarem(我们的第二个研究站点)的属性，添加这两个先前研究的每个城市样本 地区(阿尔塔米拉和桑塔雷姆)，并在机械化大豆推广的震中增加一个新的研究地点 在马托格罗索州，在里约热内卢的卢卡斯，我们将对大规模的农村和城市进行采样 居民。我们将获取卫星数据，以更新先前研究过的两个地区的覆盖范围，以及 过去30年的完整数据在新的研究地点的变化，因为我们提出了一个强有力的 比较设计，使我们能够对内源性和外源性的作用做出推断 家庭、物业和景观动态的因素。加上额外的研究区域，这将是 在亚马逊地区进行的最大规模的社会调查，有1000多处房产和2500多处 户型，面积1万多平方公里。

This project addresses the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon by focusing on the linked processes of social, economic, demographic, and environmental change. In earlier studies we examined the role of the domestic cycle on land use and distinguished between period and cohort effects, and discovered that a property cycle explained more of the dynamics of change in land cover than a household cycle, particularly after the first generation. In this phase of the study we expand our focus to address the role played by the social and economic integration of urban and rural areas, and the role of one exogenous change that appears to be transforming the landscape: the growing role of capital investment in large-scale mechanized agriculture and ranching. In the previous phase, we conducted follow up surveys in previously surveyed households and properties at our first study site (Altamira). In this phase, we will carry out follow up surveys in previously surveyed households and properties in Santarem (our second study site), add urban samples for each of these two previously studied areas (Altamira and Santarem), and add a new study site in the epicenter of mechanized soybean expansion in the state of Mato Grosso, at Lucas do Rio Verde where we will sample both large scale rural and urban residents. We will acquire satellite date to update the coverage for the two previously studied areas, and a complete set of data for the past 30 years of change in the new study site as we propose a strong comparative design that will allow us to make inferences about the role of endogenous and exogenous factors in household, property, and landscape dynamics. With the additional study area, this will be the largest social survey carried out in the Amazon region, with more than 1,000 properties and more than 2,500 households, covering an area in excess of 10,000 square kilometers.
