1 Chapter 8 Food for Thought: The Globalization of Agriculture

2 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

3 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

4 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

5 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

6 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

7 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

8 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

10 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

11 “ 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

13 “ 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

14 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.

15 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 Two major themes in this chapter Agriculture Figure 8.1 (p. 221) Globalization

18 Time-space convergence Winners and losers in the global economy Free trade and comparative advantage Figures 8.6 and 8.7 (p. 230)) Export economy Traditional economy

19 North American Free Trade Agreement (NAFTA) Implemented January 1, 1994 between the United States, Canada, and Mexico Decreased and eventually eliminated tariffs to encourage economic activity Dramatically increased trade between the three nations, from $337 billion in 1993 to $1.182 trillion in 2011.

20 NAFTA and Mexico Mexican comparative advantage in some agricultural crops Reduction in traditional peasant lifestyles and crop mixes Monoculture production for export: problems Economic rationale has adverse cultural and social effects Zapatista uprising

21 Globalization Figures 8.8 and 8.9 (p. 231)) Amazon roads and deforestation

22 Resistance to Globalization and Industrial Agriculture LDCs object to agricultural subsidies in the United States and the European Union: Unfair trade practices MDC consumers object to: Oil-based production system Environmental damage from pesticides, herbicides, and fertilizers Unethical, inhumane treatment of animals Monoculture mass production threatens food security Emphasis on low nutrition processed foods Weakened local culture and traditions

23 Responses: Local Food Movement Restaurants and Chefs Promoting Local Food Organic Farming Urban and Community Gardens Grass-fed, free range ranching Farmer’s Markets Community Supported Agriculture (CSAs) Figure 8.10 (p. 232))

25 Output per unit land per unit time (e.g., tons per acre per year). Yield The intentional cultivation of crops and raising of livestock. Agriculture An industrialized, corporate form of agriculture organized into integrated networks of agricultural inputs and outputs controlled by a small number of large corporations. The collecting of roots, seeds, fruit, and fiber from wild plants and the hunting and fishing of wild animals. Hunting and Gathering Agribusiness Large-area farms or ranches with low inputs of labor per acre and low output per acre. Extensive Agriculture

26 Goods such as equipment and buildings used to produce other goods. Capital Agriculture in which a large amount of human work is applied per unit of output. Labor-Intensive Agriculture in which a large amount of capital is applied per unit of output. Small-area farms and ranches with high inputs of labor per acre and high output per acre. Intensive Agriculture Capital-Intensive Agriculture A large estate that produces a single cash crop. Mainly found now in the tropics. Plantation Agriculture that takes place in the immediate surroundings of a permanent settlement. Sedentary Agriculture

27 The original invention of farming and domestication of livestock 8,000–14,000 years ago and the subsequent dispersal of these methods from the source regions. First Agricultural Revolution A period of technological change from the 1600s to mid-1900s that started in Western Europe, beginning with preindustrial improvements such as crop rotation and better horse collars, and concluding with industrial innovations to replace human labor with machines and to supplement natural fertilizers and pesticides with chemical ones. Artificial watering of farmland. Irrigation Second Agricultural Revolution The application of biological science to the development of better strains of plants and animals for increasing agricultural yields. Green Revolution also known as the Third Agricultural Revolution

28 Self-sufficient agriculture, usually small scale and low tech, primarily for direct consumption by the local population. Subsistence Agriculture that uses a large area of land for production of a single crop year after year. Monoculture A farming method in tropical areas in which wild vegetation is cleared and burned before crops are planted. When the soil fertility is diminished, farmers abandon the land to restore itself naturally, and they move to new areas where they repeat the process. Also known as slash-and-burn agriculture. Agriculture primarily for the purpose of selling the products for money. Commercial Agriculture Shifting Cultivation

29 An integrated agricultural system in which crops are grown and fed to livestock. Mixed Farming The general class of activity for which land is used by humans in a particular area. Land Use The use of satellite images of the earth’s surface. The general class of material or vegetation that dominates the surface of the land in a particular area. Land Cover Remote Sensing Domesticated animals such as cows, sheep, and poultry that are raised and managed to produce meat, milk, eggs, wool, leather, etc. Livestock

30 Imports and exports between countries that are unrestricted by tariffs, quotas, or excessive approvals and paperwork. Free Trade The increasing economic, cultural, demographic, political, and environmental interdependence of different places around the world. Globalism A measure of how much distance discourages movement between places, based on the time, energy, or dollar cost that must be expended. Migratory movement of herders and their animals according to the availability of grazing land. Nomadism Friction of Distance

31 The interaction between global processes and local lifestyles. This continuum is a two-way process in which the local and the global shape each other. Global-Local Continuum The rate at which the time separating two places decreases because of improvements in transportation or communication technology. When one region is relatively more efficient at producing a particular product compared with other regions. Comparative Advantage Time-Space Convergence

32 After completing this chapter, you will be able to: Differentiate among agricultural landscapes. Understand how and why the same crops and livestock are produced in different ways in different regions of the world. Recognize different land uses in satellite images. Use remote sensing to study land use change.
