Human Ecology in Geography

• Explores complex interactions between humans and their natural, built, and social environments
• Examines how human activities impact the environment and how environmental changes affect human behavior and societal development
• Emphasizes feedback loops that emerge from these relationships, leading to continuous cycles of adaptation and modification

Components of Human Ecology

• Interdependence: Humans rely on natural resources (food, water, shelter) while ecosystems are influenced by human interventions (agriculture, industry, urbanization)
• Adaptation: Human societies develop technologies, cultural practices, and institutions to survive in specific environmental conditions
• Modification: Humans modify their surroundings triggering environmental changes, requiring further social or economic adjustments
• Feedback Loops: Cyclic interactions where environmental changes caused by humans lead to societal responses, impacting the environment again. Classified as:
  • Positive feedback loops: Amplify changes, leading to instability or environmental degradation
  • Negative feedback loops: Stabilize the system, promoting balance through corrective actions

Examples of Feedback Loops

• Agriculture and Soil Fertility:
  • Human Action: Farmers use crop rotation to prevent soil exhaustion and maintain fertility.
  • Environmental Impact: Healthy soil continues to yield crops, maintaining agricultural productivity.
  • Feedback Response: The environment (soil) remains productive, requiring few changes to farming practices. This negative feedback promotes environmental sustainability.
• Urbanization and Pollution:
  • Human Action: Rapid urbanization leads to construction of roads, industries, and housing.
  • Environmental Impact: Increased air, water, and noise pollution; loss of green spaces and biodiversity.
  • Feedback Response: Pollution leads to health issues, increasing demands for stricter environmental policies. However, urban growth may continue unchecked, exacerbating these problems. Positive feedback leads to a cycle of environmental degradation unless mitigated by regulation.

The Morphology of Landscape

• Sauer's concept of "landscape morphology" explores how landscapes evolve through the interaction between physical environments and cultural activities.
• Landscapes evolve through historical processes.
• Natural Landscape: The unmodified environment (geology, climate, vegetation)
• Cultural Landscape: A landscape modified by human activities (agriculture, urban development, construction)
• Culture as an Agent of Change: Culture is a primary force in shaping landscapes, using the environment as a medium for human action. Different cultures leave distinct imprints (settlements, agriculture, trade).

Historical Approach to Landscape Change

• Sauer emphasized the importance of historical analysis to understand how landscapes evolve over time.
• Each landscape has a unique history shaped by successive natural and cultural processes.
• Reconstructing these layers of transformation is needed to study landscapes fully.
• Example of landscape evolution: A rural village turning into a suburban town due to expanding infrastructure.

Critique of Environmental Determinism

• Sauer challenged the notion that environmental factors alone determine human behavior.
• He argued that human agency plays a crucial role in shaping landscapes.
• Different cultures respond to the same environmental conditions in unique ways.

Holistic Study of Landscapes

• Sauer promoted a comprehensive approach to studying landscapes, integrating both physical and cultural geography.
• To understand landscapes, consider physical elements (soil, vegetation, climate) and cultural aspects (agriculture, settlements, architecture)

Locational School of Thought in Geography

• Developed as part of the quantitative revolution in geography (1950s-1960s)
• Emphasizes location, spatial patterns, and relationships among geographical phenomena.
• Aims for objective, measurable, and predictive knowledge by studying spatial organization.
  • Mathematical models: Used for analyzing spatial relationships, predicting future patterns, and optimizing resource allocation
    • Gravity Model: Predicts level of interaction between two places, based on their size and distance.
    • Central Place Theory: Explains hierarchical arrangement of towns/cities based on their functions/service areas
  • Accessibility, Connectivity, and Distance: Focuses on roles of distance, transportation, and accessibility in shaping spatial patterns.
  • Predictive Modeling and Spatial Planning: Aims to help urban planners and policymakers forecast changes and allocate resources efficiently.
    • Example: Urban planners use models to predict population growth and plan infrastructure.
  • Spatial Organization and Regional Development: Studies regional organization at various scales (local, regional, global), impact on economic development, and regional disparities.

Limitations of the Locational School

• Neglect of human and cultural factors: Criticized for failing to consider subjective, emotional, and cultural aspects of human behavior.
• Assumption of rational behavior: Models often assume individuals/businesses act rationally to minimize costs/maximize benefits.
• Static assumptions in dynamic environments: Struggles to account for rapid changes in economic, social, and environmental conditions.
• Ethical concerns: Reliance on technical solutions can overlook implications like gentrification or displacement.
