Example of Regional Early Warning System products for Central and South America.
In this example, fuel types have been interpreted from landcover data (ESA GlobCover Project).
Hear fi re intensity (HFI, kW/m) in grasslands is identifi ed using a fi re danger-based fi re rate of spread
model (Forestry Canada Fire Danger Group
1992
) and an estimated grassland fuel load of 3 t/ha
danger information is used to support many different short- to long-term fi re man-
agement activities: daily resource mobilization at ongoing wildfi res, presuppression
resource positioning to initial attack new fi re starts, prescribed burn planning (pre-
scription determination), justifi cation of operational budgets, predicting post-fi re
effects, carbon emissions accounting, long-term fi re and forest management plan-
ning, modeling fi re and climate change impacts, and resource-sharing within coun-
try and bilaterally. In terms of daily operational fi re management decisions, fi re
danger information is applied to nationally derived guidelines for fi re control and
use (Table

). For countries that have national fi re danger rating systems in place,
daily fi re danger information is usually produced by collecting data from national
