4. An Application of Geospatial Analysis: Environmental Indications and Warning Environmental Issues - Societal Stress Food production, freshwater resources, water/air pollution, land use change (deforestation, desertification, urbanization) Affect public health, agriculture and industrial development, demographic patterns, local through national political alliances,economic growth, infrastructure planning, crisis response capabilities……. Affect political, economic and social dynamics And are exacerbated by: continued rapid population growth and migration natural hazards and weather variability (shock) events

5. Value of GIS Technology Environmental Issues are spatial in nature with global to local origins Environmental Issues are dynamic (process and time series) Environmental Issues are subject to natural changes, anthropogenic stressors and shock events GIS facilitates trend analysis and ‘what if’ scenarios GIS provides a strong interface to remote sensing sources Visualization is a strong analysis and communication tool GIS provides a platform for the integration of other data

19. Summary “Digital Earth” will introduce new ways for researchers to assess interactions of humans and nature. Land use change dynamics such as urbanization can be readily captured by satellite remote sensing. Subnational (disaggregated) population models assist analysis of risk due to land use change, or natural hazards. Cartographic modeling is of value to visualize change dynamics and explore implications. Data are becoming more complete, precise and accurate. Trends and alternative scenarios can be modeled as well as assist in their evaluation. Built up spatial information systems can be used to examine “what if” scenarios conduct rapid assessment of real events.
