Bio

Dr. Roy Ryder is a Professor of Geography in the Department of Earth Sciences at the 麻豆传媒. He received the B.Sc. (Honors) and M.Sc. degrees from the University of Glasgow, Scotland. He also completed a one-year graduate program in remote sensing (Diploma in Photogrammetry) at the same university. His Ph.D. was obtained at the University of Florida.

Dr. Ryder taught Geography at the University of Costa Rica for 4 years. He also directed graduate programs for 8 years at the Panamerican Center for Geographical Studies in Quito, Ecuador.  That center is sponsored by the Organization of American States and Dr. Ryder worked with students and guest faculty members from almost every country in the Americas.

While in Scotland, Dr. Ryder was principally concerned with research on landforms with particular emphasis on glacier retreat in southeastern Iceland (at Breidamerkurjokull) and periglacial features in the Scottish Hebrides (Rhum). In Ecuador, he investigated a wide range of geographical phenomena including landslides caused by earthquakes in the Andes, prehistoric landforms created by pre-Inca cultures, and long-term land use change in Quito, the capital city.

His doctoral research at the University of Florida involved the study of soils and agriculture in the Central Cordillera of the Dominican Republic. His main concern was to test his scientific evaluations of site suitability for crops with the empirical knowledge of local farmers. But he also looked at the environmental and socio-cultural factors which influence how farmers choose which crops to grow, their perception of local soil types (folk soil taxonomy), and diversity in farming technology.  Dr. Ryder also had the opportunity of cooperating in Florida Sea Grant waterfront management projects designed to investigate the impact of liveaboards on the coastal environment and map abandoned vessels which cause severe water pollution and present obstacles to navigation.

Most of his research while teaching at 麻豆传媒 has been concerned with urban studies including additional work on land use change in Quito and an in-depth investigation of employment and economic development in the pioneer towns in the Ecuador Amazon region. He currently is interested in long-term land use change in downtown Mobile, Alabama.
