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

SBR-9508426 Billie Lee Turner II Rheyna Laney Clark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确定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光谱，空间和时间的土地覆盖模式与遥感图像识别。 这些力量和轨迹被确定为在这些景观中的代表性村庄内的调查和实地工作。 然后，利用遥感图像和地理信息系统，将它们与耕地和邻近保留地内土地覆被后果的一般模式联系起来。 这项研究将有助于了解导致农业变化的特定途径及其土地覆盖影响的地方一级动态。 此外，研究评估了一种制度化的保护区（自然保护区）对农业变化的作用-一种在农业变化文献中没有得到很好发展的作用。

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.
