Slash and burn (shifting cultivation) is a subsistence farming method, common in tropical regions, where farmers cut and burn vegetation to release nutrients into the soil, farm the plot until fertility drops, then abandon it and clear a new area, repeating the cycle.
Slash and burn is exactly what it sounds like. Farmers cut down (slash) the vegetation in a patch of forest, let it dry, and set it on fire (burn). The ash acts like a one-time fertilizer dump, loading the soil with nutrients. Farmers plant crops on that plot for a few years until the soil wears out, then abandon it and clear a new patch nearby. That cycle of moving from plot to plot is why the broader system is called shifting cultivation. The old plot is left fallow so the forest can regrow and the soil can recover, sometimes for decades.
In AP Human Geography, this is a classic example of subsistence agriculture practiced in tropical climates like the Amazon Basin, Sub-Saharan Africa, and Southeast Asia, where heavy rainfall leaches nutrients out of the soil quickly. The CED lists slash and burn and shifting cultivation by name (EK IMP-5.A.2) as agricultural practices that alter the landscape. At small scales with long fallow periods, the system is sustainable. When population pressure shortens the fallow time or commercial logging and ranching move in, the result is permanent deforestation, biodiversity loss, and land cover change.
This term lives in Topic 5.10 (Consequences of Agricultural Practices) in Unit 5 and directly supports learning objective AP Human Geography 5.10.A, which asks you to explain how agricultural practices have environmental and societal consequences. The CED's essential knowledge (EK IMP-5.A.2) names both slash and burn and shifting cultivation in its list of landscape-altering practices, right alongside terraces, irrigation, and deforestation, so it's fair game on the exam. It also connects backward in Unit 5, since shifting cultivation is one of the oldest subsistence farming systems and a textbook example of extensive agriculture (lots of land, low inputs per acre). If you can explain why the cycle works in the tropics and what happens when the cycle breaks down, you've got the kind of cause-and-effect reasoning FRQs reward.

Deforestation (Unit 5)
Slash and burn is one of the main human drivers of tropical deforestation. Traditional shifting cultivation lets forest regrow, but shortened fallow periods and commercial pressure turn temporary clearings into permanent land cover change, exactly the environmental effect EK IMP-5.A.1 describes.
Subsistence Agriculture (Unit 5)
Shifting cultivation is the poster child of extensive subsistence farming. Families grow food for their own consumption using lots of land and little technology, which contrasts sharply with intensive commercial agriculture in core countries.
Carrying Capacity (Units 2 and 5)
The whole system depends on having enough land to leave old plots fallow for years. When population growth pushes the land past its carrying capacity, fallow periods shrink, soil never recovers, and the practice stops being sustainable. That's a clean Unit 2 to Unit 5 link.
Climate Change (Unit 5)
Burning forest releases stored carbon into the atmosphere and removes trees that would absorb it. Large-scale slash and burn, like in the Amazon, shows up in questions linking agricultural practices to global environmental consequences.
Expect this term in multiple-choice questions that ask you to match an agricultural practice to its region, climate, or environmental consequence. A typical stem describes a tropical farming system where plots are abandoned after a few years, and you identify it as shifting cultivation, or it asks for the environmental effect (deforestation, soil degradation, land cover change). No released FRQ has required the term verbatim, but Topic 5.10 is built for free-response prompts that ask you to explain environmental consequences of an agricultural practice. Slash and burn is one of the easiest practices to use as evidence because the cause-and-effect chain is so clear: burning gives short-term fertility, repeated clearing gives long-term deforestation. Don't just define it. Be ready to explain why it happens where it does (nutrient-poor tropical soils) and what happens when it scales up.
Both are strategies for dealing with soil exhaustion, but they solve it in opposite ways. Crop rotation keeps the farmer on the same field and changes the crops (planting nitrogen-fixing legumes one season, grains the next) so the soil never fully depletes. Shifting cultivation keeps the crops roughly the same and changes the field, abandoning worn-out plots for freshly burned ones. Quick check for the exam: rotation moves the crops, shifting moves the farmer.
Slash and burn means cutting and burning forest vegetation so the ash fertilizes the soil for farming; shifting cultivation is the larger cycle of farming a plot, abandoning it, and moving to a new one.
It is practiced mainly in tropical regions like the Amazon, Sub-Saharan Africa, and Southeast Asia, where heavy rain leaches soil nutrients quickly.
It's a form of extensive subsistence agriculture, meaning low inputs and lots of land, with food grown for the family rather than for sale.
Traditional shifting cultivation is sustainable when fallow periods are long enough for forest to regrow, but population growth and commercial land use break the cycle.
The CED (EK IMP-5.A.2) names slash and burn and shifting cultivation as practices that alter the landscape, with deforestation, biodiversity loss, and land cover change as the major environmental consequences.
On the exam, the strongest answers explain the cause-and-effect chain: burning gives short-term fertility, repeated clearing at scale gives long-term deforestation.
It's a subsistence farming method where farmers cut and burn forest vegetation so the nutrient-rich ash fertilizes the soil, farm the plot for a few years, then abandon it and clear a new one. The CED lists it in Topic 5.10 as a practice that alters the landscape.
Almost. Slash and burn is the clearing technique (cut, dry, burn), while shifting cultivation is the whole rotating system of moving between plots over time. The AP CED lists both, and on the exam they're usually treated as the same practice.
No, not inherently. With small populations and fallow periods long enough for forest regrowth, the system is sustainable and has been used for thousands of years. It becomes destructive when population pressure or commercial expansion shortens fallow times, causing permanent deforestation and soil degradation.
Crop rotation changes what's planted on the same field each season to preserve soil fertility, while shifting cultivation abandons exhausted fields entirely and moves to newly cleared land. Rotation moves the crops; shifting moves the farmer.
Mostly in tropical regions like the Amazon Basin, Sub-Saharan Africa, and Southeast Asia. Heavy tropical rainfall leaches nutrients from the soil fast, so burning vegetation is the most practical way for subsistence farmers to get a temporary fertility boost.
