Earth System Science
Variability: How is the global Earth
system changing?
Forcing: What are the primary causes
of change in the Earth system?
Response: How does the Earth
system respond to natural and
human- induced changes?
Consequences: What are the
consequences of changes in the
Earth system for human civilization?
Prediction: How well can we predict
future changes to the Earth system?

Example: Rift Valley Fever
Predicting regional outbreaks of RVF using satellite data on rainfall,
ENSO and vegetation
Example: Lyme Disease
Identifying vector-friendly environmental conditions using satellite
data on rainfall, vegetation, proximity to settlements
Example: Malaria
Textural-contextual classifications significantly
increase landcover mapping accuracy using high
resolution data such as Ikonos.
