Vegetation fire, good or bad?

Fire has been around for quite a time in Madagascar. It has been to renew grazing areas for cattle, to clear land for agriculture, also used by the Dahalo to cover their tracks after stealing zebus, and some other obscure reason such as showing angriness.

 Initially, fire is just a tool, and faire itself cannot be good or bad. Later, the area burnt expanded exponentially, and fire is responsible for almost all deforesattion occuring in Madagascar through slash and burn cultivation (very small part from charcoal production, but even then, the two are related) and the fire is becoming an environmental problem and is the number one environmentalist ennemy.

Fire management, fire supression?
