Land cover change is the alteration of the natural vegetation and physical surface of land, usually through agricultural expansion or modification, such as clearing forests for cropland or draining wetlands for fields. In AP Human Geography, it's a major environmental consequence of farming (Topic 5.10).
Land cover change is what happens when humans swap out what's naturally growing on the land for something else. A rainforest becomes a soybean field. A wetland gets drained and turned into cropland. A grassland becomes a cattle ranch. The "cover" part literally means what covers the ground, so this term is about the physical surface of the Earth changing, not just how people use it on paper.
In the CED, land cover change is listed as one of the environmental effects of agricultural land use in EK IMP-5.A.1, alongside pollution, desertification, soil salinization, and conservation efforts. EK IMP-5.A.2 names the practices that drive it: slash and burn, terracing, irrigation, deforestation, draining wetlands, shifting cultivation, and pastoral nomadism. Every one of those alters the landscape, which means every one of them is a potential land cover change example on the exam.
Land cover change lives in Topic 5.10 (Consequences of Agricultural Practices) in Unit 5 and supports learning objective 5.10.A, which asks you to explain how agricultural practices have environmental and societal consequences. It's also a perfect lens for the human-environment interaction theme that runs through the whole course. Agriculture is the single biggest way humans have reshaped Earth's surface, and land cover change is the umbrella term the exam uses for that reshaping. If a question shows you a before-and-after of a landscape transformed by farming, this is the vocabulary they want.

Draining Wetlands (Unit 5)
This is land cover change in action. When farmers drain a wetland to plant crops, the natural marsh cover is replaced by farmland. Practice questions often use wetland drainage as the textbook example of land cover change, so know this pairing cold.
Slash and Burn/Shifting Cultivation (Unit 5)
Slash and burn clears forest cover by cutting and burning it, which is land cover change at the local scale. The twist with shifting cultivation is that farmers move on and let the forest regrow, so the change can be temporary if population pressure stays low.
Sahel and Desertification (Unit 5)
Desertification is an extreme form of land cover change where overgrazing and overfarming turn semi-arid grassland into desert. The Sahel in Africa is the go-to AP example, and it shows that land cover change isn't always intentional conversion. Sometimes it's degradation.
Carrying Capacity (Unit 2)
Here's the cross-unit thread. Population growth pushes societies to feed more people, which drives agricultural expansion, which drives land cover change. Clearing more land can raise carrying capacity in the short run but degrade it long-term if the soil gives out.
On multiple choice, land cover change shows up two ways. First, identification questions ask which scenario is an example of it (draining wetlands and clearing forests are the classic correct answers). Second, disambiguation questions test whether you can tell it apart from other environmental effects in EK IMP-5.A.1. For example, pesticides leaching into groundwater is pollution, not land cover change, even though both come from farming. On free-response questions, this term supports cause-and-effect explanations. The 2025 SAQ on global milk and pork production asked about spatial patterns of agriculture and land use, exactly the territory where explaining how livestock production transforms landscapes earns points. When you use it in an FRQ, name the specific practice (deforestation, irrigation, wetland drainage) and explain what the land looked like before and after.
Land cover is what's physically on the surface (forest, grass, wetland, crops). Land use is what humans do with it (farming, grazing, housing). They overlap a lot, but you can change use without changing cover (a forest becomes a managed timber plantation) and the AP CED specifically tests land cover change as the environmental effect, meaning the physical vegetation and surface actually changed.
Land cover change is the alteration of natural vegetation and surface characteristics of land, mainly caused by agricultural expansion and modification.
The CED lists it in EK IMP-5.A.1 as one of five environmental effects of agriculture, alongside pollution, desertification, soil salinization, and conservation efforts.
Practices that cause it include deforestation, slash and burn, draining wetlands, irrigation, terracing, shifting cultivation, and pastoral nomadism (EK IMP-5.A.2).
Pesticide runoff into groundwater is pollution, not land cover change. Land cover change means the physical surface itself was transformed.
Desertification, like in the Sahel, is land cover change caused by degradation rather than deliberate conversion.
Population growth and rising food demand are the underlying drivers, which links this term back to carrying capacity in Unit 2.
Land cover change is the alteration of the natural vegetation and surface of land, usually through agriculture, like clearing a forest for crops or draining a wetland for fields. It's tested in Topic 5.10 as an environmental consequence of agricultural practices.
No. Chemicals seeping into groundwater is pollution, a separate environmental effect in EK IMP-5.A.1. Land cover change requires the physical surface itself to be transformed, like a wetland becoming a cornfield. The exam loves testing this exact distinction.
Land cover is what's physically on the ground (forest, grassland, wetland), while land use is the human activity on it (farming, grazing). The AP exam tests land cover change as the environmental effect, meaning the actual vegetation or surface was altered.
Deforestation for cropland, draining wetlands to create fields, slash and burn clearing, building irrigation terraces, and overgrazing that turns Sahel grassland into desert. All of these replace natural cover with a human-modified surface.
Desertification is one type of land cover change, but not the whole category. Desertification specifically means productive land degrading into desert, while land cover change covers any surface transformation, including deliberate conversions like forest to farmland.
