1 CHAPTER 11 AGRICULTURE

2 Organic agriculture (introduction) producing crops without any man made materials (pesticides, fertilizers) Most organic food sold in core countries Organic crops produced in all levels of countries but shipped to core countries Benefits environment with less chemicals in water and soil

3 Economic Activities Primary- jobs that work directly with nature (farming, hunting, forestry) Secondary- take primary products and manufacture them into other products

4 Tertiary- service jobs (do not produce anything but their service- teachers, lawyers) –Quaternary- exchange of money (bankers) –Quinary- exchange of information (scientist)

5 By looking at what sector is dominant, you can see the countries development Example –Guatemala 50% ag/ 35% tertiary (semi periphery) –Canada 2% Ag/ 75% tertiary (core)

6 Where did Ag begin? Agriculture- the deliberate tending of crops or livestock to produce food –½ the grains made in the US are consumed by livestock

7 History- hunting, fishing, and gathering preceded farming Used ancient tools and perfected things like fire First Rev. known for the planting of crops First Ag. Revolution

8 Ag. Allowed people to settle down in one place Plant domestication- planting and harvesting crops for your own use Root crops- grown by plant selection of plant’s roots Seed crops- produce plants from seeds

9 Most think agriculture began in Iran (fertile crescent) other areas of early ag are Nile, west Africa, and China (theory maybe the first?) Crops diffused through exploration (corn was taken from Central America to US and Europe)

10 Animal domestication (using animals like sheep, goats and dogs in daily life) –Began when people became settled and attached to villages (protection and food) –Used animals for meat, labor, and milk

11 Modern day first ag. rev Hunters and gathers still exist in Africa but running out of room Subsistence Ag: growing enough food to survive Shifting cultivation- found in tropical areas where you farm the land until it is dry and then move to new land –Slash and burn- where people burn underbrush to clear and fertilize new soil

12 Colonialism tries to end subsistence farming for cash crops (cotton, rubber, coffee, tea) –Colonies made money; locals starved from lack of food –Still a problem today in former colonial countries

13 Second Ag. Revolution Used machines in farming –Paired with the industrial revolution and took agriculture from subsistence to producing extra –Brought new crops from colonization –Fertilizers were used and land sectioned off

14 Von Thunen Man who created a model to explain how farming and economics were linked through transportation Setup towns in rings revolving around the market –Market –Gardening and dairy (spoils fast) –Forestry (heavy!) –Grains (lighter to carry) –Livestock (walk themselves)

15 Third Ag. Revolution Using technology to manipulate agriculture and increase crop yields Green Revolution: (step 1 in third rev.) occurred in Asia with crossbreeding of rice to create a “SUPER RICE” –Then used to create wheat and corn through hybrid seeds

16 Used worldwide: hybrid seeds, pesticides, fertilizers, irrigation Allowed people to grow more crops to feed their population (but still poor distribution) Problems: disease resistant plants, water pollution, expensive to buy the seeds, soil pollution Most farmers worldwide are women; many farms now changing into commercial farms

17 Agriculture and Landscape Cadastral system- how land is defined and divided –Rectangular survey- geometric division (straight lines like out west’s township and range) –Metes and bounds- division based on natural boundaries (east coast) –Longlot- land in narrow section that centers around a road or water –Primogeniture- old idea of only passing land to eldest son

18 Villages Round village Walled village Grid village Nucleated (cluster) settlement Different regions have different ways to represent wealth and success based on size or location of homes

19 Commercial agriculture- growing and harvesting crops to sell for a profit –Created monoculture growing of one crop –Cash crops in periphery and semi periphery still occurring today with core owners of the farms Refrigerated trucks helped change transporting food over long distances

20 Cash crops & plantation agriculture Colonial powers brought cash crops to poor countries Plantation agriculture- crops grown on large estates

21 Multinational corporations- (Dole) have protected against countries getting power over the land to ensure that the company stays in control –Guatemala gov. coup sponsored by a fruit company

22 Cotton and rubber two most used cash crops Luxury crops- tea, cacao, coffee, and tobacco Coffee the second most traded commodity in the world with US buys half “fair trade” coffee is when farms meet qualifications and register to get “fair value” for their coffee

23 Livestock- raising of domesticated animals for meat and byproducts Mediterranean- farming of crops that can only grow in the Med. Climate (olives, grapes, citrus) Illegal drugs- usually grown in periphery/ semi periphery and sold to core –Coca & marijuana- South America –Opium and heroin- south asia –92% of cocaine enters US through Mexico

24 Impacts of commercial agriculture –Fishing industry part of agriculture and fishing stocks are decreasing –Clearing of land causes soil erosion and chemical runoff –Livestock increase with fast food chain increase has led to deforestation of the land for grazing land

25 Agribusiness- businesses that support farms and create a connection of production and exchange –Tyson chicken- runs all parts of the industry from the baby chicks to the processed fried frozen chicken Collective farms- communist experiment to have everyone work on one big farm (FAILED)

26 Loss of productive land –Urban sprawl taking over farm land for housing developments
