Socio-Ecological Systems' Adaptation to Climate Variability

Dr. Xiangming Xiao is director of the Earth Observation and Modeling Facility (EOMF), located at the University of Oklahoma's Stephenson Research and Technology Center in Norman, Oklahoma.  The EOMF is a member of both (1) Department of Microbiology and Plant Biology, College of Arts and Sciences, and (2) Center for Spatial Analysis, College of Atmospheric and Geographic Sciences, the University of Oklahoma.

Dr. Xiangming and researchers at the EOMF focus on geospatial science, technologies and applications in bio-, geo- and health- sciences, specifically in the areas of agriculture, forestry, ecology, biodiversity, land use and land cover changes, water quality, climate, infectious diseases and public health. It promotes community remote sensing and citizen science to address the grand challenges in our dynamic and rapidly changing planet Earth and the society.Applications of remote sensing and GIS in ecosystems science and natural resources; land use and cover changes; ecosystem service assessment; biogeochemistry of terrestrial ecosystems; ecosystem modeling at large spatial scales; integrated impact assessment of climate change; ecology and epidemiology of infectious diseases.

Dr. Xiao's work on the Oklahoma EPSCoR RII award addresses two significant research objectives, including:

  1. Establishment of a first-of-its-kind, statewide, socio-ecological observatory;
  2. Development of a fully integrated socio-ecological modeling and prediction system that is designed to integrate qualitative and quantitative approaches and to systematically examine insights from both disciplinary and integrated perspectives.
