Step 1: Walk through the farming cycle in order.
Select a forest patch, cut and burn the vegetation, sow crops in the ash-enriched soil, harvest for a couple of seasons, then abandon the plot and move to a new one.
Step 2: Tie each stage to a characteristic.
The burning stage gives the 'slash and burn' label. The short harvest stage gives the low soil-fertility limitation. The move-on stage gives its shifting, non-permanent nature. The whole cycle is done with hand tools and family labour for the family's own food needs.
Final Answer:
Tracing the cycle shows the same core traits: temporary clearing by burning, brief cropping, land rotation through fallow periods, and subsistence farming with simple tools.$\boxed{\text{Cyclical slash-burn subsistence farming}}$
