Unit 5: Agriculture & Rural Land-Use Patterns and Processes

Agricultural practices are shaped by the physical environment and bioclimatic conditions. Different climates, such as Mediterranean and tropical, influence farming methods. Agricultural intensity can be categorized into intensive farming, which has high labor and capital inputs, and extensive farming, characterized by lower inputs often on larger plots of land. Key factors impacting agricultural distribution include climate, landforms, and soil nutrients. Environmental possibilism suggests that technology can mitigate natural limitations, contributing to sustainable|tgyy

Shifting Cultivation: Common in tropical regions; involves clearing and burning land for crops.
Nomadic Herding: Found in dry regions; involves moving livestock for sustenance.
Livestock Ranching: Extensive commercial farming in arid areas.
Commercial Grain Farming: Grows grains mainly for consumption in mid-latitude regions.
Market Gardening: Intense farming of fruits and vegetables in temperate zones.
Plantation Agriculture: Specialized in cash crops, relying on cheap labor in tropical regions.
Mixed Crop and Livestock: Combines crop production and livestock farming.
Dairy Farming: Intensive in mid-latitudes, requiring substantial labor and machinery.

Rural Settlement Patterns

Methods to establish land ownership include Metes and Bounds and Township and Range, affecting rural settlement patterns like clustered, dispersed, and linear configurations.

Agricultural Origins

Domestication is centered in key hearths with fertile soil, leading to surplus food and population growth.

Diffusion of Agriculture

Mechanisms include contagious diffusion, relocation diffusion, and stimulus diffusion, with modern approaches like the Green Revolution focusing on high-yield crops and technology.

The Second Agricultural Revolution

Triggered by the Industrial Revolution, it led to mechanization, crop rotation, and urbanization, resulting in increased food production.

The Green Revolution

Focused on enhancing food production through high-yield varieties and chemical inputs while also raising concerns about environmental impact and social disparities.

Economic Patterns of Agriculture

Distinguishes between subsistence and commercial farming; highlights economic impacts, including monocropping, agribusiness, and global food distribution patterns.

The Von Thünen Model

Explains land use based on transportation costs in concentric rings around a market.

Environmental Impact

Landscape alteration leads to significant environmental issues, including pollution and soil erosion, highlighting the delicate balance between agriculture and sustainability.
