Doctoral Dissertation Research: Agricultural Change and Its Implications for Land-Cover Transformations in Madagascar

9508426比利·李·特纳二世莱娜·兰妮·克拉克大学论文改进研究：农业变化及其对马达加斯加土地覆盖变化的影响本论文改进研究的主要目标是识别和解释马达加斯加自然保护区附近农业景观中发生的农业变化路径，并将这些变化轨迹与遥感图像可识别的光谱、空间和时间土地覆盖模式联系起来。这些力量和轨迹是通过在这些景观中具有代表性的村庄的调查和实地工作来确定的。然后，利用遥感图像和地理信息系统将它们与不仅在耕地而且在邻近保护区内的土地复盖后果的一般模式联系起来。这项研究将有助于理解导致农业变化的特定路径及其土地复盖影响的地方一级的动态。此外，这项研究还评估了一种制度化保护区(自然保护区)在农业变化中的作用--这一作用在农业变化文献中没有得到很好的发展。

SBR-9508426 Billie Lee Turner II Rheyna Laney Clark University Dissertation Improvement Research: Agricultural Change and Its Implications for Land-Cover Transformations in Madagascar The primary objective of this dissertation improvement research is to identify and explain the paths of agricultural change occurring in agrarian landscapes adjacent to natural reserves in Madagascar, and to associate these trajectories of change with spectral, spatial, and temporal land-cover patterns identifiable with remotely-sensed imagery. These forces and trajectories are identified with surveys and field work within representative villages in these landscapes. They are then linked with the use of remotely-sensed imagery and GIS to their general patterns of land-cover consequences within not only the cultivated areas but within the adjacent reserves. The research will contribute to an understanding of the local-level dynamics that give rise to particular paths of agricultural change and their land-cover impacts. In addition the research assesses the role of one kind of institutionalized protected area (natu re reserves) on agricultural change--a role that has not been well developed within the agricultural change literature.
