项目摘要

PROJECT ABSTRACTLiving with Deforestation Analyzing Transformations in Welfare and Land Use on an Old Amazonian Frontier Tropical deforestation is a striking form of land cover transformation resulting in a complex mosaic of shifting land-use patterns across space and time. While research on forest conversion has been prolific, there has been relatively less attention given to long term impacts on the socio-economic welfare of frontier inhabitants along with the reciprocal effects of income and wealth on land use. Moreover, there is limited understanding of how post-deforestation trajectories are related to employment, migration, and inequality. These lacunae are directly related to the difficulty of obtaining the data required to track and evaluate these processes. Nevertheless, as the "old frontier" expands in tropical forest zones, it is critical to understand the dynamic economic and landscape processes that follow deforestation. This project will address these issues by adding a fourth round to a spatial panel of farm households, expanding the database to multiple scales with new secondary data, improving classification methods for remote sensing data, and modeling land use decisions and their consequences in the heavily deforested state of Rondônia, Brazil. A principle outcome of this project will be a public dataset that can be used by researchers from various disciplines to analyze questions related to the dynamic and spatial processes on forest frontiers. Specifically, spatially-referenced household panel survey data collected (from the same households and farm lots in four time periods) in the core study area of Ouro Preto do Oeste will be combined with several sources of data that cover an expanded study region: cadastral maps matched with satellite imagery to quantify land cover change; spatial data on biophysical factors, markets, and public infrastructure; and secondary data at multiple scales from official sources such as the current agricultural census. A second outcome will be improved land cover classification methods developed through traditional ground referencing and household-reported land use histories. Lastly, this research will draw more general conclusions regarding the co-evolution of land use and socio-economic welfare through combined analysis of complementary secondary data that expands the temporal and spatial range of the detailed household survey and linked remote sensing data.
热带森林砍伐是土地覆盖变化的一种引人注目的形式,导致土地利用模式在空间和时间上的复杂变化。虽然关于森林转换的研究已经很多,但相对较少关注对边境居民社会经济福利的长期影响以及收入和财富对土地使用的相互影响沿着。此外,人们对森林砍伐后的轨迹与就业、移民和不平等之间的关系了解有限。这些缺陷与难以获得跟踪和评价这些进程所需的数据直接相关。然而,随着“旧边疆”在热带林区的扩展,了解毁林后的动态经济和景观过程至关重要。 该项目将解决这些问题,方法是在农户空间小组中增加第四轮,利用新的二级数据将数据库扩大到多个尺度,改进遥感数据的分类方法,并在巴西森林遭到严重砍伐的朗州建立土地使用决策及其后果的模型。该项目的一个主要成果将是一个公共数据集,可供各学科研究人员用来分析与森林边界动态和空间进程有关的问题。 具体来说,收集的空间参考家庭面板调查数据将把欧罗普雷托核心研究区(四个时间段内来自相同家庭和农场地块)的数据与覆盖扩大研究区域的几个数据来源结合起来:与卫星图像相匹配的地籍图,以量化土地覆盖变化;关于生物物理因素、市场和公共基础设施的空间数据;以及来自官方来源(如当前的农业普查)的多个尺度的二级数据。 第二项成果将是通过传统的地面参照和家庭报告的土地使用历史改进土地覆盖分类方法。最后,这项研究将通过对补充性二级数据的综合分析,就土地使用和社会经济福利的共同演变得出更一般性的结论,这些数据扩大了详细住户调查和相关遥感数据的时间和空间范围。
