What is the name of the food production strategy, which is characterized by "slash and burn, swidden agricultural techniques used to clear lands for farm plots, which tend to be exhausted after a few years? "?

This food production strategy is what is commonly referred to as unsustainable agriculture. The agriculture process removes the delicate balance of flora and fauna in jungle or forested areas and quickly depletes the land of any remaining nutrients and is therefore unsustainable. The lack of concern or care for the natural environment can lead to larger catastrophes like the creation of scorched earth or desert-like environments where plant and animal life cannot return for decades, if ever.
