1 Primarily for direct consumption by a local population, usually small scale and low tech Subsistence Agriculture Primarily for purpose of selling products for money, often monocultures for economies of scale Commercial Agriculture Agriculture & Rural Land Use – Key Topics

2 Large-area farms or ranches Low inputs of labor & low output per acre Extensive Land Use Small-area farms or ranches High inputs of labor & high output per acre Intensive Land Use Rice paddies, southeast China Cattle ranch, northeast Colorado

3 Large amount of human work is applied per unit of output Labor-Intensive Agriculture Large amount of capital (equipment and buildings used to produce other goods) is applied per unit of output Capital-Intensive Agriculture Top picture – Labor-intensive corn raising in central Mexico. Bottom picture – Corn exported from capital- intensive U.S. farms to the Mexican market

4 Subsistence – predominantly low-income regions Intensive subsistence – subtropical monsoon areas Shifting cultivation – tropical forests & savannas Nomadic herding – semiarid and arid lands Commercial – predominantly high-income regions Crop farming – more humid climates Livestock ranching - drylands

5 Probable culture-hearths of agriculture shift from hunter-gatherer to agricultural societies Invention of farming & domestication of livestock (8,000– 14,000 years ago) + diffusion from several source regions = shift from hunter-gatherer to agricultural societies First Agricultural Revolution

6 Second Agricultural Revolution Technological changes (starting 1600s in Western Europe; spread by 1800s to North America) Began with new methods: crop rotation, better horse collars Later innovations: replace human labor with machines, supplement natural fertilizers & pesticides with chemical Beginnings of commercialization of agriculture (production of surplus for trade); enabled widespread urbanization

7 Climate and natural environment Culture Economic factors Simplified von Thünen model of agricultural land use (1826) Factors influencing location of agriculture Medium transportation cost items (corn, soybeans, mixed farming) More extensive land use – medium rent Urban market High transportation cost items (vegetables, eggs, dairy, flowers) Intensive land use – high land rent Lowest transportation cost items (forestry, wheat, livestock ranching) Most extensive land use – lowest land rent

8 Chile’s agricultural exports Vegetables and orchards near Santiago Regional produce warehouse in Chile Market in Slovakia

9 Third Agricultural Revolution Since 1960s - hybridized grains for better yields (“Green Revolution”) - greater reliance on synthetic fertilizers - genetically engineered crops - vertical integration of ownership (e.g., Cargill, ConAgra, ADM) - globalization of production A partial list of ConAgra’s brands Swiss MissHunt’s Van Camp’sMarie Callender’s WessonHebrew National Slim JimEgg Beaters RosaritaChef Boyardee ReddiWipPam Peter PanOrville Redenbacher’s Healthy ChoiceBanquet

10 “Green Revolution” – 1960s -1980s Rice plant Rice - staple food for 2.5 billion Asians - provides 2/3 of calories for Asians with rice-based diets Green Rev – Raised yields * Improved rice strains * Greater use of fertilizer * Increase use of irrigation Asia’s rice production grew at annual rates of 3.0% until 1980s Yield growth rate exceeded high pop. growth rates of the time Sources: FAO, IRRI (research organization devoted to rice) – part of global CGIAR effort at improving yields of staple crops worldwide

11 “Post-Green Revolution” (since 1980s) Green Revolution Plusses: Countries self-sufficient in rice or even exporters (Thai, Viet). Poor people benefited as yield increases caused real price of rice to drop. Problems Successes led to less concern about food security, and less investment in irrigation, agric research, and rural infrastructure. Growth rate in rice production declined during 1985-95 due to drop in growth rate of rice yields. In most places, despite increasing use of fertilizers, further increases in yields became harder to achieve and more costly. www.fao.orgwww.fao.org: Mobilising science for global food security www.fao.org

12 Globalization of the Cut-Flower Industry Kenya has become the European Union's biggest source of flower imports and overtaken Israel as market leader. It has a 25% market share, beating Colombia and Israel, which each have about 16%. Two thirds of these blooms go to the Netherlands, which dominates the trade in cut flowers worldwide through its auction halls where Dutch wholesalers buy flowers for re-export to markets as far away as the United States and Japan. Valentine's Day is a big date for Kenyan growers, thanks to the country's perfect match of high altitudes and equatorial sunshine. Roses make up 74% of Kenya's flower exports, followed by carnations which are the most popular flower in Britain at less romantic times because they last longest.

13 Third Agricultural Revolution Benefits Reduced uncertainties in agriculture Greater global exchange of ag products Increased yields Costs Increased dependence on fossil fuels Reliance on chemical inputs Less global diversity of food products Concentration of pollutants

17 Least-Cost Location Theory Cost minimization is half of profit maximization equation (along with maximizing revenues) Cost minimization theory: - labor-cost minimization - transportation cost minimization Cost minimization - an industrial location strategy that seeks to minimize what the firm pays to produce and distribute its products or services

18 Maquiladoras – foreign-owned assembly plants in Mexico (mostly textiles and consumer electronics) Over 11,500 maquiladoras along border with U.S.; employ 2 million+ Mexicans Revenues from maquiladoras, exceed make up 85% of trade between Mexico and U.S. Minimizing Labor Cost Average work week is 60-70 hours; wages about $5.75 per day. Women are 70% of maquiladora workforce. Since 2000, some maquiladoras have closed as corporations move assembly-line jobs to even lower- wage countries, mainly China. Sources: PBS & Ingolf Vogeler

19 Fixed and Variable Costs Influence the Optimum Location for Economic Activity Classical economic geography models focus mainly on the variable cost of transportation

20 Determining the best location for a mfg. plant with raw materials in Minnesota, Florida, and Texas & the market in New York (but with differing amounts of raw mat’s needed)

21 Weber Triangle Three factors: –Transport costs –Labor costs –Agglomeration Transport costs: –One market and two sources: Equal distance and shipping costs dictates a market location Two weight-losing materials results in an intermediate location

22 Weber’s Theory of Location Weber’s theory results in 3 generalizations: –Using pure materials in the production process will always dictate a market location –Weight-loss materials usage will pull the plant closer to the sources –Intermediate location chosen most often No handling costs at terminal

23 Weber’s Theory of Location Labor Costs: –Location chosen always has least combined costs A location my have higher transport costs, but more inexpensive labor –Isocheims: lines of equal transport cost –Isodapane: line of total transport costs (sum of isotims)

25 Weber’s Theory of Location Agglomeration: –Weber recognized that clustering will result in a per unit savings –Example:

26 Raw Material Oriented Tendency for industry to locate near its source of raw materials in order to save on transport costs Usually occurs when raw materials lose weight in the production process (e.g., paper, steel) Transportation Cost Minimization

27 Market Oriented Tendency for industry to locate near population centers in order to save on transport costs Occurs when product is more costly to transport than raw materials (e.g., beverages, glass) Transportation Cost Minimization

28 Break-of-Bulk Oriented Location between sources of raw materials and markets – for products that must be divided and shipped from a central point of entry Intermodal transportation – e.g., moving from rails to trucks or ships to trucks, or ports to pipelines Transportation Cost Minimization

29 Where is the best location for a steel manufacturing plant? Recipe for steel (traditional) Coal = 2 to 3 tons (+ energy*) Iron ore = 1½ to 2 tons Limestone = ¼ to ½ ton Mix all solid ingredients. Heat at about 600º F until thoroughly melted.* Pour molten blend into molds. Cool and serve. Makes one ton of finished steel.

30 The recipe for making steel has changed (new technology) How has this affected the location of modern steel- producing areas?

31 Shipbreaking industry, Bangladesh Shipbreaking yards in Bangladesh alone dismantle about 90 giant ships a year, mostly oil tankers, generating millions in revenue, employing tens of thousands, and providing a significant proportion of the iron and steel used by local industry. However, there is a dark side to the industry in which the workers must toil in extremely hazardous conditions that frequently lead to death or serious injury and which is tremendously harmful to the environment.... A majority of ships are built in South Korea and China, filling orders placed by Japan, the UK, the US, Norway, Singapore and Denmark. Until the 1970s, shipbreaking was done in the countries of origin, using heavy machinery on salvage decks. But increasing environmental regulations and labour costs resulted in the transfer of this work -- first to Korea and Taiwan, and then to South Asia after the Asian Tigers upgraded away from this work.

32 Consider transport costs of a car’s components. Where’s a good place to locate your assembly plant?

33 Over 50,000 U.S. auto- making jobs in these foreign- owned plants (New York Times data and map, 2005)

34 The cost of transporting data has declined to near zero Source: Probe Research, Inc., Telcordia (Bellcore); Progressive Policy Institute. Low transmission costs, plus ability to digitize data, revolutionized the location choices for high-tech industry

35 “Post-Fordist” Production – High Tech Industry Adapting the traditional models of economic geography Greater flexibility of production Less reliance on storage of inventory – seek prompt delivery of goods needed for production (“just-in-time”) Suppliers’ location Need to have access to fast delivery systems (= airports) Agglomeration of management Still occurs! High-tech innovators locate closer to airports; universities; amenities; venture capital (tends to be a “footloose” industry) Internationalized spatial division of labor Lower labor costs needed for production – industry locates manufacturing in lower wage areas (secondary) but tech and management stays in core area (quaternary)
