Detalhes da Resposta

Shifting cultivation is an agricultural practice involving cultivating alternative plots to allow for natural regeneration. This practice involves clearing an area of forest or vegetation, planting crops for a few years until the soil becomes depleted, and then moving on to clear another area while the previous area regenerates naturally. This process is repeated over time, with farmers shifting from one plot to another, hence the name "shifting cultivation." It is commonly used in areas with low population density and is often a subsistence-based farming practice.
