Land use in agriculture by the numbers
The source article for this piece can be found on the FAO Statistics Division website.
Globally agricultural land area is approximately five billion hectares, or 38 percent of the global land surface. About one-third of this is used as cropland, while the remaining two-thirds consist of meadows and pastures) for grazing livestock.
Regional distribution of agricultural land use is a combination of local agri-climatic edaphic – soil –conditions, and socio-economic drivers.

Can pasture be used to sequester carbon?
And some will also argue that there are ways to manage pasture to better sequester carbon. But other studies suggest this is rarely the case . Yes, there are ways to minimize emissions with better managed pasture. But I can’t help but wonder if there’s also better things we could be doing with all that land.
Is cutting meat and dairy good for the environment?
Energy. When Katherine wrote that cutting meat and dairy is one of the best things you can do for the planet, I think many of us focused on the methane emissions inherent in beef and dairy production. But that’s by no means the only environmental impact.

What is the focus of A Focus on Agricultural Land?
A Focus on Agricultural Land. by Cynthia Nickerson and Allison Borchers. How land is used and changes in land use have implications for commodity production and trade, soil and water conservation, bioenergy supply, climate change adaptation, and many other policy issues. A complex set of factors, including commodity prices; production technology;
How did market forces affect crop production?
Market forces, changes in farm programs, and changes in technology affect the supply and demand for land used for crop production. Between 1949 and 1969, cropland used for crops decreased by 54 million acres and then peaked at 383 million acres in 1982, when no cropland was diverted through Government-acreage reduction programs.
What are the factors that affect land use?
A complex set of factors, including commodity prices; production technology; demand for land for residential, commercial, and industrial development; and agricultural and bioenergy policies, can induce land-use change as landowners respond to market conditions and try to maximize the returns to their land.
Why are some acres converted to urban uses?
Some acres are converted to urban uses to serve the needs of a growing population. These factors have combined to cause a long-term net decline in grazing acreage, from over 1 billion acres in 1949 to 741 million acres in 2007. Every year, some rural land is converted to developed uses.

Cropland is roughly concentrated in the central regions of the contiguous United States; pasture and range in the more arid West; and forest land (both grazed and not grazed) in the East, where the topography and precipitation patterns are conducive to growing trees.
Why is land use important?
Land use and land-use change have important economic and environmental implications for commodity production and trade, soil and water conservation, and other policy issues. Changes in land use occur for various reasons, and some changes are less reversible than others.
What are nonagricultural land uses?
Nonagricultural land uses include ungrazed forest-use land, nonagricultural special uses, urban land, and miscellaneous other categories that are not separately inventoried (wetlands, rural residential, mining areas, etc.).

What are the factors that affect cropland?
A variety of factors—such as commodity prices, weather, changes in technology, and Government programs—affect how cropland is used. Between 2002 and 2012, a combination of high commodity prices and drought conditions influenced trends in cropland use. Cropland harvested, which accounts for the majority of cropland use, increased by 8 million acres.
How many acres of forest land were lost in 2012?
Between 2002 and 2012, grazed forest-use land exhibited a small decline of 4 million acres. The distribution of both agricultural and non-agricultural land uses varies substantially across the country based on factors such as soil, climate, and Federal and local policies and programs.
Why has urban land use increased?
Although urban land use makes up a small fraction of the land base (3 percent), it has continually increased over time in response to population and economic growth. Increases in urban land are often offset by declines in undeveloped rural land (e.g., cropland, pasture/range, and forestland).
Where is cropland located?
Cropland is concentrated in the Corn Belt and Northern Plains regions, where several States (including Iowa, Kansas, and Illinois) have more than half of their land base devoted to cropland. Grassland pasture and range accounted for a large share of land in the Mountain (60 percent) and Southern Plains (59 percent) regions.
Is land use change reversible?
Land-use changes between undeveloped categories are generally reversible— but, once developed, urban land rarely reverts back to an undeveloped use. The National Resources Inventory reveals most new land development between 2007 and 2012 took place on land that was formerly in forestland and cropland uses.
