Subsistence vs. Commercial Farming (LDC ‘s) vs. (MDC’s) Differ in five ways: Purpose Percentage of farmers Machinery Farm size Farms and other industries
Purpose Subsistence: Commercial: People produce food for their own consumption Some surplus may be sold, but not the primary purpose Commercial: Grow crops and raise animals for sale off the farm Agricultural products are sold to food processing companies
In the U.S. and Canada only 2% Percentage of Farmers LDC’s: More than one half of the workers are engaged directly in farming MDC’s: Less than one tenth of the workers are engaged directly in farming In the U.S. and Canada only 2%
Labor Force in Agriculture, 2005 Fig. 10-3: A large proportion of workers in most LDCs are in agriculture, while only a small percentage of workers in MDCs are engaged in agriculture.
Machinery LDC’s: MDC’s: Mostly rely on hand tools and animal power Lack effective transportation systems Lack technology MDC’s: Tractors, combines, pickers, and planters have replaced most manual labor Railroads, highways, and trucks get crops to markets without spoiling Biological research produce higher crop yields and healthier animals Electronics provide precise data
Combines on Wheat in Kansas Combines can reap, thresh, and clean crops like wheat in a single operation.
Farm Size LDC’s: MDC’s: Very small Very large (444acre avg. in U.S.) Most are family owned and operated
Tractors, per cropland Fig. 10-4: Tractors per 1000 hectares of cropland. Use of machinery is extensive in most MDC agriculture, but it is much less common in LDCs.
Farms and other industries LDC’s: Very isolated MDC’s: Tied closely to other businesses Not isolated they are integrated into a large food-production industry 20% of U.S. labor work in food production and agribusiness services
11 Main Agricultural Regions 5 Regions important in LDC’s 6 Regions important in MDC’s Derwent Whittlesey points out a correlation between agriculture and climate Cultural preferences can explain some agricultural differences in areas of similar climate
World Agriculture Regions Fig. 10-5b: Locations of the major types of subsistence and commercial agriculture.
Agriculture in Less Developed Countries Characteristics of subsistence regions Produce for own consumption Large percentage of workforce engaged in agriculture Few mechanical aids Very small parcels of land Isolated from economy
Rice Harvesting, Indonesia Wet rice is often harvested by hand in Asia.
Agriculture in Less Developed Countries Most people in the world are subsistence farmers. *Less developed=More farmers* Types of subsistence agriculture: Shifting cultivation Pastoral nomadism Intensive subsistence agriculture Plantation farming
Labor Force in Agriculture, 2005 Fig. 10-3: A large proportion of workers in most LDCs are in agriculture, while only a small percentage of workers in MDCs are engaged in agriculture.
Shifting Cultivation NOT Shifting “Agriculture” Two distinguishing characteristics *Slash-and-burn agriculture *Only grow on cleared land for 2-3 years
Shifting Cultivation in Guatemala Dense vegetation has been cut and is being burned to open land for farming.
Shifting Cultivation Cycle Cut down big trees As they fall they take Undergrowth is leaving economically down the smaller cleared by machete useful ones trees or long knife Debris is burned Rain washes ashes Fields are prepared under carefully into the soil by hand controlled conditions Crops grown for Field is left fallow New patch of land 3yrs or less for many years is selected
World Agriculture Regions What are some consequences of Shifting Cultivation? Hint: think of the geography in the three major areas it is prevalent.
Shifting Cultivation Northeast India
Types of Crops S.E. Asia: Upland Rice South America: Maize and Manioc Africa: Millet and Sorghum
What do their fields look like? For the Kayopo tribe of Brazil they are arranged in concentric circles. Why? One swidden will have a variety of intermingled crops
Who owns the land? The village as a whole Each family is allocated a patch of land One quarter of the worlds land area is occupied by shifting cultivation But only 5% of the worlds people engage in it
The Future of Shifting Cultivation Half of the earth’s tropical rain forests have been destroyed. Being replaced by logging, cattle ranching, and cultivation of cash crops. Its critics view it as a preliminary step in economic development Its defenders consider it the most environmentally sound approach If eliminated it could upset the traditional diversity of cultures in the tropics This type is shrinking but will not disappear quickly
Pastoral Nomadism Based on the herding of domesticated animals Dependent on animals rather than crops for survival. The animals provide: Milk Clothing Tents
Pastoral Nomadic Diet What was noticeably missing from the list of things the animals provide? They rarely slaughter the animals. Their diet is still primarily grains.
What? If they depend on animals rather than crops for survival…but don’t eat the animals… What gives??? They get their grains in different ways: Some trade animal products for grain Some have part of their group stay put Some hire workers to grow it Some plant, wander around, then return to harvest Some stay in one place long enough to grow and then move on
Animals, Animals, Animals The animals are chosen because of cultural or physical characteristics Middle East: Dromedary Camel, Sheep, Goats Central Asia: Bactrian Camels, Horses A typical nomadic family would need: 25-60 Sheep/Goats 10-25 Camels
Pastoral Nomads in Iran Qashqai nomads using paved roads to move their animals near Shiraz, Iran.
Nomads DO NOT wander aimlessly They have a strong sense of territory They have precise migration patterns based on knowledge: The areas physical characteristics Cultural characteristics Most likely water sources Political stability Some practice transhumance
The Future of Pastoral Nomadism Declining form of agriculture No longer play an important role in transportation and communications In the future it will be increasingly confined to areas that cannot be irrigated or lack raw materials
Intensive Subsistence Agriculture Intensive implies that farmers must work harder to subsist on a parcel of land Found in densely populated E.,S., and S.E. Asia Two types: Intensive Subsistence, Wet Rice Dominant Intensive Subsistence, Wet Rice Not Dominant
Characteristics Agricultural Density Fragmented Plots Waste virtually no land
Intensive, Wet Rice Dominant Most dominant type of agriculture in S.E. China, E. India, and S.E. Asia Labor intensive and elaborate process All family members contribute to the effort Double Cropping
World Rice Production, 2005 Asian farmers grow over 90% of the world’s rice. India and China alone account for over half of world rice production.
Intensive, Wet Rice Dominant Steps to Growing Rice seed is planted in a nursery Fields are prepared and plowed Field is flooded Seedlings are transferred and planted in the flooded field Each plant is cared for individually until harvest
Intensive, Wet Rice Not Dominant This is an ancient form of agriculture, think of places like Medieval Europe Dominant in interior India, and N.E. China Wheat is the most important crop Other grains and legumes are also grown Cash crops include; cotton, flax, hemp, and tobacco In milder areas two harvests possible
Land Ownership in China Communist Government Owns Organized agricultural producer communes in 1949 Communes dismantled Villagers now sign contracts to farm portions as private individuals Transition has been difficult
Plantation Farming Form of commercial agriculture found in LDC’s Generally owned or operated by Europeans and North Americans Crops grown for sale primarily in MDC’s
Plantations Large farm specializing in one or two crops Latin America- Grow coffee, sugar cane, bananas Asia- Grow rubber and palm oil Workers must be brought in Crops processed at the plantation
