The SAFARI 2000 (S2K) Project was an international science initiative to study the linkages between land and atmosphere processes in the southern African region. In addition, SAFARI 2000 examined the relationship of biogenic, pyrogenic, and anthropogenic emissions and the consequences of their deposition to the functioning of the biogeophysical and biogeochemical systems.

This initiative began in 1999 and concluded in 2001, and was built around a number of ongoing, already-funded activities by NASA, the international community, and African nations in the southern African region. Historical data from 1973 through 1995 were compiled as background data.
