Collaborative Research on Living with Deforestation: Analyzing Changes in Welfare and the Environment on an Old Amazonian Frontier

与毁林同生分析亚马逊老边界福利和土地利用的变化热带毁林是土地覆盖变化的一种显着形式，导致跨越空间和时间变化的土地利用模式的复杂马赛克。虽然关于森林转用的研究成果很多，但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的关注相对较少。此外，人们对毁林后的发展轨迹与就业、移民和不平等的关系了解有限。这些漏洞与难以获得跟踪和评估这些进程所需的数据直接相关。然而，随着“老边界”在热带林区的扩张，了解森林砍伐后的动态经济和景观过程至关重要。该项目将通过增加第四轮农户空间小组、利用新的次级数据将数据库扩展到多个比例尺、改进遥感数据的分类方法以及对森林砍伐严重的巴西隆多尼亚州的土地使用决定及其后果进行建模来解决这些问题。该项目的一个主要成果将是一个公共数据集，来自不同学科的研究人员可以使用它来分析与森林边界上的动态和空间过程有关的问题。具体地说，在Ouro Preto do Oust核心研究区域收集的(在四个时间段内从相同家庭和农场收集的)空间参照家庭小组调查数据将与覆盖扩大研究区域的几个数据来源结合在一起：地籍地图与卫星图像匹配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；以及来自官方来源的多尺度二级数据，如当前的农业普查。第二个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复盖分类方法。最后，这项研究将通过对补充的次级数据的综合分析，得出关于土地利用和社会经济福利共同演变的更一般的结论，从而扩大详细的住户调查和关联的遥感数据的时间和空间范围。

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.
