Explanation:

There are multiple different types of farming, and they mostly depend on the level of development of a country or a particular area of a country. The farming methods range anywhere from organic and self-sustaining farming to subsistence farming and everything in between. Subsistence farming is a primitive method of farming and it can mostly be found in the less developed countries.

Subsistence farming is a type of farming where the people produce enough only for their own needs, and usually don't have anything left for trade on the market. This method of farming is mostly found in sub-Saharan Africa, South America, and Southeast Asia. In order for the people to get to land for farming they use the slash-and-burn method, which is basically cutting and burning down all of the vegetation, and in its place create farmland. This is not a good method on the lng rn though because the soil is not of high quality not is treated properly, so the people just move on and destroy another piece of land once the one they use loses its fertility.
