Study Notes on Origins, Patterns, and Settlements of Agriculture

Origins, Patterns, and Settlements of Agriculture

Introduction to Agriculture

  • Learning Objective: Explain the connection between physical geography and agricultural practices.
  • Essential Question: What is the connection between physical geography and agricultural practices?
  • Agriculture is the process where humans alter landscapes to raise crops and livestock for consumption and trade.
    • Key Elements Influencing Agriculture:
    • Physical Geography: Soil types and landforms affect agricultural practices. For instance, coffee thrives on hillsides in warm climates (e.g., Kenya, Colombia) and olives, grapes, and figs in Mediterranean regions.
    • Climate: Long-term weather patterns determine suitable crops. E.g., cotton requires nutrient-rich soil, whereas sorghum flourishes in nutrient-poor environments.
  • Examples:
    • Economic factors also influence agriculture decisions; consumer demand can sway what farmers cultivate.

Physical Geography and Agriculture

  • Agriculture's dependence on water resources is critical; regions like the Sahel face significant challenges due to aridity.
  • Soil nutrient levels dictate crop viability:
    • Cotton = nutrient-rich soil
    • Sorghum = nutrient-poor soils, such as tropical rainforests
  • Human Alterations to Environment: Techniques to enhance agriculture include:
    • Irrigation
    • Terrace farming
    • Deforestation
    • Desertification
    • Wetland drainage
  • Agricultural Activities: Vary with physical constraints and economic development.

Climate and Agriculture

  • Influence of Climate on Agriculture: Absolute necessity determining types of crops and livestock based on local climate conditions.
  • Exceptions: Highest latitudes/elevations and extreme precipitation areas support minimal agricultural activity due to lower population density historically.
  • Adaptations in Challenging Climates: Example of greenhouses in cold climates (Iceland, Greenland) allows for crop production.
  • Cultural Traits Relating to Agriculture: For instance, religious views influencing meat choices in certain regions (e.g., hogs in predominantly Muslim or Jewish areas).

Economic Factors and Agricultural Practices

  • Types of Agriculture:
    • Subsistence Agriculture: Limited to immediate needs of farmers and families, usually in less-developed regions, commonly small farms.
    • Characteristics: < 2 acres; difficulties in surplus production due to limited resources and technology.
    • Commercial Agriculture: Focused on profit and productivity, prevalent in developed regions and now expanding in emerging economies (e.g., China, Brazil).
    • Characteristics: Purchase technology, land, and training using profits.
  • Intensive vs. Extensive Farming Practices:
    • Intensive Agriculture: High inputs (labor, capital) = high yields (e.g., market gardening, plantations).
    • Extensive Agriculture: Low inputs = lower yields (e.g., ranching).

Types of Agriculture by Region

  • Global Distribution of Agriculture:
    • Intensive Commercial
    • Region: Global across core, semi-periphery, periphery.
  • Types of Agriculture Practices:
    • Intensive Subsistence Farming: Labor-intensive, e.g., rice farming.
    • Extensive Subsistence: Using few inputs, often in arid regions (e.g., nomadic herding).
  • Agricultural Types Identified by Derwent Whittlesey (1936):
    • Pastoral Nomadism: Drylands (e.g., Asia, North Africa)
    • Shifting Cultivation: Tropical regions.
    • Plantation Agriculture: Tropics/subtropics.
    • Mixed Crop and Livestock: Cold/warm mid-latitudes.
    • Dairy Farming: Associated with urban markets.
    • Commercial Gardening: Southeast U.S.

Agricultural Origins and Diffusions

  • Essential Question: Identify major centers of domestication and animal diffusion globally.
  • Agricultural Hearths: Neolithic Revolution around five major centers: Southwest Asia, East Asia, South Asia, Africa, and the Americas.
  • Impact of Agriculture:
    • Transition from hunter-gatherer societies to settled agriculture led to increased creativity and specialization of labor in early human societies.
    • Increased food supply led to population density and establishment of urban centers.
  • Major Crop Domestication Areas:
    • Examples of early crops include barley and wheat in Southwest Asia, rice in East Asia, and maize in Mesoamerica.
  • Modern Diffusion and its Consequences:
    • Diffusion paths led to global trade networks; the Columbian Exchange crucially impacted worldwide crop and animal distributions (e.g., introduction of potatoes and maize in Europe).
  • Green Revolution:
    • Aimed at improving agricultural productivity through scientific advancements; however, it also led to discussions about its sustainability and environmental impact.

Spatial Organization of Agriculture

  • Understanding spatial organization includes the influences on agricultural practices such as population density and physical geography.
  • Market-related Decisions: Proximity to urban centers increases land value influencing intensive agricultural practices.
  • Models of Land Use: Statistical models (e.g., Von Thünen Model) explain agricultural land use based on distance to market and crop perishability.

Challenges and Consequences of Agricultural Practices

  • Environmental Consequences: Impact on ecosystems due to increased agricultural mechanization and chemical use.
  • Sustainability Concerns: Current practices often lead to depletion of biodiversity and soil degradation. Individual and collective efforts through education and sustainable practices necessary for long-term resilience.
  • Societal Impacts and Gender Roles: Women's involvement in agriculture is crucial; inequality challenges persist affecting productivity.
  • Profitability Concerns: Sustainable practices often conflict with profit-driven incentives in contemporary agricultural environments.

Conclusion

  • The interconnectedness of agriculture, climate, economics, and society requires a nuanced understanding of local practices, global trade relationships, and the consequences of agricultural innovations.
