Final answer:
Slash and burn agriculture, which occurs in equatorial rainforest climates with nutrient-poor soil, is also known as swidden agriculture. It requires minimal labor and is sustainable with small populations and proper fallow periods.
Step-by-step explanation:
“Slash and burn” agriculture is also known as d) swidden agriculture. This agricultural practice is carried out in equatorial rainforest climates, where the soil is poor and can support only small populations. Farmers clear a patch of forest, dry the vegetation, then burn it to enrich the soil with the ashes of the burnt plants as fertilizer. This form of agriculture is also characterized as land extensive farming and is deemed caloric efficient due to its minimal labor requirements. It is sustainable as long as the population size remains small and fallow periods are respected to allow forest regrowth.
