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.

SBR-9508426 Billie Lee Turner II rheyana Laney Clark University论文改进研究：本论文改进研究的主要目的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土地覆盖光谱、空间和时间模式联系起来。这些力量和轨迹是通过在这些景观中有代表性的村庄进行调查和实地工作确定的。然后将它们与遥感图像和地理信息系统的使用联系起来，不仅在耕地内，而且在邻近的保护区内，它们的土地覆盖后果的一般模式。这项研究将有助于了解产生特定农业变化路径及其对土地覆盖的影响的地方一级动态。此外，研究还评估了一种制度化保护区（自然保护区）对农业变化的作用——这一作用在农业变化文献中尚未得到很好的发展。
