This annual lecture sponsored by the Singapore Journal of Tropical Geography will be delivered by Professor May Yuan, who is the Ashbel Smith Professor of Geospatial Information Sciences in the School of Economic, Political, and Policy Sciences at the University of Texas at Dallas. She studies temporal GIS and its applications to geographic dynamics. Her lecture title is 'Calling GIS Innovations to Address Tensions in Tropical and Subtropical Geography’. Below is the abstract of her talk.
John Nystuen (1963) claimed four kinds of tensions that trigger big geographic problems: (1) historical tensions between the past and present activities; (2) dimensional tensions between point-, line-, or area-occupying activities; (3) space-time tensions between current activities; and (4) scale of observation and unit areas. His premise centered upon the need to reveal how the spatial associations of human activities and nonhuman processes influence geographic elements of interest. Tropical and subtropical regions enjoy highly diverse populations, species, and environments. Consequently, complex activities, processes, and their spatial associations prompt all four kinds of tensions across the regions. Examples include the historical tension of land use land cover change, the dimensional tension of in-situ weather observations for an area, the space-time tension of traffic congestion, and the demand to select a proper scale of observation and unit area of analysis for a given problem. Increases in population growth, climate variability and environmental volatility further intensify these tensions and exacerbate three overarching challenges facing the region: climate change and biodiversity, food and water security, and human health; all are of global significance. This talk attempts to expand upon Nystuen’s tension ideas to explore new GIS conceptual frameworks and methods to address these major geographic problems in tropical and subtropical geography.
