It is kind of natural. Supposedly when lightning would strike the dead trees a forest fire would start and burn down everything. Our ancestors realized that the land left behind from that fire was extremely fertile after a while. Also, it is bad to overuse a piece of land. Land needs time to rest and re-fertilize. While slash and burn may not be necessary, it is a good alternative. Disadvantages: You could make a mistake and burn a bit more than what you planned. It is time consuming because you must wait for the land to become useful again

Answer:
Salient features of this agriculture are :
(i) Forests are cleared and trees are burnt to make the land available for cultivation.
(ii) Digging stick is mainly used for cultivation.
(iii) Mainly root crops and food crops are grown for their own use.
(iv) After 2 years when the soil becomes impoverished they move to another forest area.
(v) Productivity is very low as there is less use of natural fertilisers and pesticides, etc.
