Satellite image-based mapping of tropical forests is vital to conservation planning. Standard methods for automated image classification, however, limit classification detail in complex tropical landscapes. In this study, we test an approach to Landsat image interpretation on four islands of the Lesser Antilles, including Grenada and St. Kitts, Nevis and...

Louis T. Steyaert, R.G. Knox
2008, Journal of Geophysical Research D: Atmospheres (113) 1-27
Over the past 350 years, the eastern half of the United States experienced extensive land cover changes. These began with land clearing in the 1600s, continued with widespread deforestation, wetland drainage, and intensive land use by 1920, and then evolved to the present-day landscape of forest regrowth, intensive agriculture, urban...

J.A. Mason, J. B. Swinehart, H. Lu, X. Miao, P. Cha, Y. Zhou
2008, Geomorphology (102) 351-363
The climatic controls on dune mobility, especially the relative importance of wind strength, remain incompletely understood. This is a key research problem in semi-arid northern China, both for interpreting past dune activity as evidence of paleoclimate and for predicting future environmental change. Potential eolian sand transport, which is approximately proportional...
Mangrove forest distributions and dynamics in Madagascar (1975-2005)
C. Giri, J. Muhlhausen
2008, Sensors (8) 2104-2117
Mangrove forests of Madagascar are declining, albeit at a much slower rate than the global average. The forests are declining due to conversion to other land uses and forest degradation. However, accurate and reliable information on their present distribution and their rates, causes, and consequences of change have not been...
