1 Ch. 10 Agriculture Key Issues 1-4

2 What is agriculture? Agriculture is the deliberate modification of Earth’s surface through cultivation of plants and rearing of animals to obtains sustenance or economic gain. Where did agriculture start? Where does it happen today in MDCs? In LDCs?

3 Hunter Gatherers Pre-agriculture Small groups (> than 50)
Men hunt/women gather Daily search for food Still done by a ¼ million people today (Artic, Africa, Australia, South America Nomadic, isolated

4 Invention of Agriculture
Vegetative Planting Seed Planting Earlier Reproductions of plants by direct cloning Began in SE Asia (climate, fishing) Taro, yam, banana, palm Dog, pig, chicken West Africa, South America Later Reproduction of plants by planting seeds Began in India, China, Ethiopia, Mexico and Peru SouthWest Asia-First to integrate with animal domestication (cattle, sheep, goats) Cutting stems, dividing roots

6 Vegetative Planting Hearths
Vegetative planting mainly began in SE Asia Fig. 10-1: There were several main heaths, or centers of origin, for vegetative crops (roots & tubers, etc.), from which the crops diffused to other areas. Carl Sauer suggested that Southeast Asia was a primary hearth.

7 Seed Agriculture Hearths
Important hearths: Ethiopia, South/Central America, China and India Fig. 10-2: Seed agriculture also originated in several hearths and diffused from those elsewhere.

8 Labor Force in Agriculture
Is this a good thing in terms of development?

9 Classifying Agriculture
Commercial Farming Subsistence Farming Off the farm On the farm Food for commercial consumption Sold to food-processing companies Less than 10% of workers Rely on machinery (transportation, science, GPS) Few, large farms Agribusiness v=SRhI7vMuDf0 Food for family consumption Consumed on the farm More than 50% of workers Rely on people or animals Many, small farms Most important distinction: is food consumed on or off the farm???

10 Agriculture in LDCs Where are agricultural regions in less developed countries? Shifting Cultivation Pastoral Nomadism Intensive Subsistence Plantation

11 Occupies the largest percentage of the world’s land area
Shifting Cultivation Subsistence Climate: Humid, low latitude (hot and rainy) Characteristics: Slash-and-burn agriculture Clearing-farming-moving Depletes soil nutrients Small, community owned farms Hand tools and potash ¼ of world’s land to feed less than 5% of population Difficulties: Limited land, loss of nature, poor soil Declining—more people, less land Competition for land New technology and commercial farming Debt-for-nature swap =WBSg5sGh2nQ Occupies the largest percentage of the world’s land area

12 Occupy only their own territory, move with the seasons
Pastoral Nomadism Subsistence Climate: Arid and semiarid climate Characteristics: Herding of domesticated animals 20 % of Earth, 15 million people Size of the herd matters Eat more grains than meat Middle East: camel>goat>sheep Central Asia: horses Regular migration and Territoriality, Transhumance Once thought to be a stage Difficulties: Government forced resettlement =6lycmTmNCBI Occupy only their own territory, move with the seasons Known as Transhumance

13 Intensive Subsistence Agriculture
Climate: Varies Densely populated areas (E, S, and SE Asia) Characteristics: Small, fragmented plots after generations High agricultural density Farming by hand, some animals and tools Wet rice dominant—South China Wet Rice Not Dominant—North China Double Cropping Difficulties: Reorganization after Communism =dT6gjb48_N0 Practiced by the largest percentage of the world’s people…mostly in Asia Subsistence

14 Plantation Farming Climate: Found in the tropics and subtropics
Commercial…but still in LDCs Climate: Found in the tropics and subtropics Characteristics: Commercial Agriculture Found in LDCs, owned by Europeans or Americans for profit in MDCs Difficulties: Large farms in sparsely populated areas—must import and provide for workers Plantations try to make tasks last year round and do most processing on site LDCs generate money for development by selling export crops

15 Agriculture in MDCs Where are agricultural regions in MDCs?
Mixed Crop and Livestock Farming Dairy Farming Grain Farming Livestock Ranching Mediterranean Agriculture Commercial Gardening and Fruit Farming In MDC’s, we now see less farms, less farmers…because of better efficiency through technology

16 Agribusiness In the US, farms are integrated into a large food production industry known as agribusiness Results in large farms Corporate owning of farms Heavy use of machinery Fewer farmers

17 Mixed Crop and Livestock
Location: Corn Belt—Ohio to North Dakota Characteristics: Most crops are fed to livestock Livestock supply manure Reduces variations in income throughout the year Corn and Soybeans Difficulties: crop rotation The first group to integrate seed agri and domestication of animals was SouthWest Asia

18 Dairy Farming Location: NE US, SE Canada, NW Europe
Characteristics: Dairy used to be considered luxury item Milkshed—ring surrounding a city from which milk can be supplied without spoiling. Grown from 30 to 300 miles Farms further away=butter and cheese Difficulties: Labor intensive, feeding cows in winter—high operating costs, low milk prices Declining: Higher yield from cows, more mechanized, urbanization, smaller farms not profitable The further away from the city a dairy farm is, the less likely it is to make fresh milk…what would it make instead?

19 Grain Farming Location: Kansas, Colorado, Oklahoma-Winter Wheat Belt
Dakotas, Southern Canada, Montana-Spring Wheat Belt Characteristics: Grown for consumption by humans, not animals Wheat-highest value per unit rate, world’s leading export crop Difficulties: Some firms have fields in both areas to maximize profit vs. costs Worldwide, China, the US, Russia and India produce the most commercial grain

20 Livestock Ranching Location: Semiarid/Arid land that can’t support crops Characteristics: Columbian Exchange Cattle Drives to Chicago Barbed wire  fixed location ranching Difficulties: Ranching is an inefficient use of land, mainly just in Western states Also in Spain, Portugal, Argentina, Uruguay and Brazil Sheep=New Zealand, Australia, Middle East 627E7A8B932989&feature=results_main In LDCs, dry lands are used for pastoral nomadism. In MDCs, dry lands are used for ranching.

21 Mediterranean Agriculture
Location: Southern Europe, North Africa, California, Chile, South Africa, Australia All on the Western coasts Characteristics: Olives, grapes, fruits, vegetables Horticulture=The growing of fruits, vegetables and flowers. Difficulties: losing land to housing and irrigation These are all countries known for their wine…why?

22 Commercial Gardening and Fruit Farming
Location: US Southeast Characteristics: Truck Farming= Middle English word for bartering Apples, asparagus, cherries, lettuce, mushrooms, and tomatoes Highly efficient: Machines, migrant workers, new seeds Difficulty: Cost of machinery, immigration issues for workers
