Transcript of Derwent Whittlesey's Agricultural Regions

Derwent Whittlesey's Agricultural Regions
Whittlesey
In 1936, Whittlesey identified 11 main agricultural regions, plus an area where agriculture was non-existent.
Pastoral Nomadism
- Important to developing countries
- Primarily the drylands of Southwest Asia & North Africa, Central Asia, and East Asia
- A form of subsistence agriculture based on the herding of domesticated animals
Shifting Cultivation
-Important to developing countries
-Primarily the tropical regions of Latin America, Sub-Saharan Africa, and Southeast Asia
- Clearing land for farming, by slashing vegetation and burning debris. Once farmers use up all of the nutrients, they abandon the land
-Form of subsistence farming
Eleven Regions
Whittlesey's 11 regions are divided between 5 that are important in developing countries, and 6 that are important in developed countries.
Intensive subsistence, wet rice dominant
-Important to developing countries
-Primarily the large population concentrations of East Asia and South Asia
-The term intensive implies that farmers must work intensively to subsist on a parcel of land
Intensive subsistence, crops other than rice dominant
-Important to developing countries
-Primarily the large population concentrations of East Asia and South Asia, where rice growing is difficult
-Involves the skilled use of crop rotation
Plantation
-Important to developing countries
-Primarily the tropical and sub-tropical regions of Latin America, sub-capitalized Saharan Africa, South Asia, and South East Asia
-A large commercial farm in a developing country that specializes in one or two crops
Mixed Crop and Livestock
- Important to developed countries
-Primarily the U.S. Midwest and Central Europe.
- Most common form of commercial farming in the U.S. west of the Appalachians. Also prominent in Europe from France to Russia
Dairying
- Important to developed countries
-Primarily near population clusters in the northeastern U.S., southeastern Canada, and northwestern Europe.
-Very important commercial agriculture
Grain
- Important to developed countries
-Primarily the north-central United States, south-central Canada, and Eastern Europe
- Mostly commercial
Livestock ranching
- Important to developed countries
-Primarily the drylands of western North America, southeastern Latin America, Central Asia, sub-Saharan Africa,and the South Pacific
- Commercial grazing of livestock over an extensive area
Mediterranean
- Important to developed countries
-Primarily lands surrounding the Mediterranean Sea, the western United States, the southern tip of Africa, and Chile.
-Most crops in the Mediterranean lands are grown for human consumption rather than animal feed.
-Horticulture - which is the growing of fruit, vegetables, and flowers - and tree crops form the commercial base of Mediterranean farming
Commercial gardening
- Important to developed countries
-Primarily the southeastern United States and southeastern Australia
-Agriculture in this region is sometimes referred to as truck farming. These farms grow the fruits and vegetables that are in demand in that country
