How Many Wars Are Going On Today?

According to The Human Security Brief 2006 (which updates the 2005 Human Security Report):

Notwithstanding the escalating violence in Iraq and the widening war in Darfur, the new data indicate that from the beginning of 2002 to the end of 2005, the number of armed conflicts being waged around the world shrank 15% from 66 to 56. By far the greatest decline was in sub-Saharan Africa.
