Agriculture and Rural Land-Use Patterns and Processes Notes
Unit 5: Agriculture and Rural Land-Use Patterns and Processes
Unit Overview
Agriculture began ~12,000 years ago in Southwest Asia (intentionally growing crops, raising animals).
Four agricultural revolutions have increased agricultural productivity:
First Agricultural Revolution: Origins and domestication.
Second Agricultural Revolution: Mechanization, chemicals, improved research (since 1750).
Third Agricultural Revolution (Green Revolution): Genetic advancements and agribusiness practices.
Agriculture influences and is influenced by land-use patterns, physical geography, economics, and society.
Environmental stress has increased due to modern practices.
Enduring Understandings
Resource availability and cultural practices influence agricultural practices and land-use patterns.
Agriculture evolves over time through cultural diffusion and advances in technology.
Production and consumption vary geographically, presenting diverse opportunities and challenges.
Chapter 11: Origins, Patterns, and Settlements of Agriculture
5.1 Introduction to Agriculture
Physical Geography and Agriculture: Climate, soil types, and landforms shape agricultural practices.
Example: Coffee prefers warm hillsides (e.g., Kenya, Colombia).
Economic Factors: Market proximity influences what crops are grown.
Types of Agriculture:
Subsistence Agriculture: Grows food for immediate consumption; common in less-developed areas.
Commercial Agriculture: Grows for profit; prevalent in developed countries.
5.2 Settlement Patterns and Survey Methods
Rural Settlement Patterns:
Clustered (Nucleated): Homes are grouped, fosters community.
Dispersed: Homes spread out, common in North America due to westward expansion.
Linear Settlement: Organized near transportation routes or bodies of water.
Survey Methods:
Metes and Bounds: Describing land boundaries using natural features.
Public Land Survey System: Based on rectangular plots leading to more uniform property boundaries.
5.3 Agricultural Origins and Diffusions
Agricultural Hearths:
Domestication began in regions like the Fertile Crescent, East Asia, and the Americas.
Diffusion: Spread of agricultural practices occurred globally with cultural exchanges.
Impacts: Transition from mobile hunter-gatherer societies to settled agricultural communities allowed for bigger populations and specialization in society.
Chapter 12: The Second and Third Agricultural Revolutions
5.4 The Second Agricultural Revolution
Marked by mechanization and scientific farming methods; increased productivity and efficiency.
Changes: Introduction of tools like the steel plow, mechanical reapers, and large-scale irrigation.
5.5 The Green Revolution
Introduced high-yield crop varieties and increased usage of fertilizers/pesticides.
Environmental concerns: Pollution issues due to chemical usage, changes in biodiversity, and reliance on technological inputs leading to sustainability challenges.
Chapter 13: Spatial Arrangement of Agriculture
5.6 Agricultural Production Regions
Economic influences on agricultural strategies (capital vs. land/labor costs).
5.7 Spatial Organization of Agriculture
Changes in agricultural landscape due to globalization and corporate farming.
Importance of infrastructure for the distribution of agricultural products.
5.8 Von Thünen Model
Explains land use surrounding a market based on transportation costs and product perishability. Zones:
1: Horticulture
2: Forest
3: Grains
4: Livestock
Chapter 14: Challenges and Consequences of Agricultural Practices
5.10 Consequences of Agricultural Practices
Environmental issues: Pollution, land use changes, deforestation, and soil exhaustion.
5.11 Challenges of Contemporary Agriculture
Innovations like GMOs, aquaculture, and organic farming aim to meet global food demands and sustainability concerns.
5.12 Women in Agriculture
Women play crucial roles but face significant barriers in access to resources, education, and equality in agricultural production, affecting global food security.
Conclusion
Agriculture is a complex system influenced by geography, economics, and social factors.
Sustainability and fair practices are critical challenges facing the agricultural sector today, requiring a balance between development and environmental stewardship.
