Study Notes
Agricultural Geography
- Prior to agriculture, individuals hunted, fished, and gathered food, leading to a nomadic lifestyle.
- This sustenance method persisted until the Mesolithic era (approximately 12,000-10,000 years ago).
- The Neolithic Revolution marked the shift from hunting and gathering to agriculture.
- Modern remote communities often exhibit pre-agricultural practices.
Origins of Agriculture
- Agriculture involves cultivating crops and raising livestock for sustenance and economic gain.
- Early humans domesticated plants and animals, a revolutionary event in history.
- The domestication process occurred independently in various regions.
- Agriculture spread across the globe, giving rise to agricultural hearths.
- Sedentary lifestyles emerged alongside agricultural practices, leading to permanent settlements.
- The First Agricultural Revolution describes the pivotal period of significant agricultural change.
Intentional Environment Modification
- Humans modify environments to promote beneficial plant and animal species proliferation.
- Environments are intentionally altered through processes like land clearance and tilling.
- This modification increases resource availability for plants and animals.
- Higher biodiversity is often a consequence of these modifications.
- Human activity has greatly influenced the Earth's environment.
Plant and Animal Domestication
- Domestication involves human selection and interventions to enhance plant and animal usefulness.
- Examples of these changes include enlarged crop sizes (seeds, fruits, tubers).
- Plant domestication led to the development of specific plant classifications.
- Animal domestication has led to various animal varieties.
- Domesticated species are now dependent on human interactions for their survival.
Domesticated Animals
- Domesticated animals primarily originated from socially inclined species.
- Domesticated animals usually display a greater degree of docility compared to wild counterparts.
- Domesticated animals exhibit increased productivity in terms of meat, wool, and milk.
- They perform various roles in human societies, such as transportation, pest control, aiding, and accumulating wealth.
Agricultural Diversity
- Agricultural practices have significantly varied across diverse historical periods and locations.
- Agricultural activities exist in a variety of scales, ranging from individual households to large commercial enterprises.
- These variations stem from cultural factors and geographic conditions.
Agriculture in Less Developed Countries
- Subsistence agriculture is the dominant agricultural form in many less developed nations.
- It serves to meet household needs, rather than commercial purposes.
- Various methods of subsistence agriculture exist, each adapting to specific physical and climatic conditions. Examples include shifting cultivation, and pastoral nomadism.
Shifting Cultivation
- Shifting cultivation, also known as slash-and-burn agriculture, involves clearing and burning vegetation.
- The land is used for a period until its nutrients are depleted, then abandoned.
- This method enhances soil fertility temporarily but not long term.
Pastoral Nomadism
- Pastoral nomadism is a form of subsistence agriculture centered around herding domesticated animals.
- Practice involves the movement of herds to find suitable grazing areas.
- This method is practiced in arid or semi-arid regions where rainfall is less reliable.
- In some cases, there can be a combination of nomadic and sedentary activities.
Plantations
- Plantations are a distinctive agricultural method present in less developed countries.
- This system mainly grows crops for export to wealthier nations.
- This approach often features luxury rather than necessity commodities, such as coffee and rubber.
- This practice often leads to excessive use of agricultural land leading to deforestation.
Intensive Subsistence Agriculture
- Intensive subsistence agriculture, particularly focusing on wet rice cultivation, is a distinct method.
- It is prevalent in densely populated areas.
- It involves intensive farming, often using smaller parcels of land.
Agriculture in More Developed Countries
- Agricultural practices in more developed countries often employ advanced technology.
- It leads to higher productivity and better crop yields.
- Participation in the agricultural sector is often significantly diminished.
- This sector is reliant on advanced machinery and technology, reducing the need for manual labor.
- Farms in developed nation show a greater degree of commercialization and market focus.
The Green Revolution
- Norman Borlaug played a pivotal role in the Green Revolution.
- He developed high-yielding wheat varieties, enhancing disease resistance and production potential.
- This revolution led to surplus wheat production in Mexico, and eventually, export capabilities.
- Green Revolution technologies spread globally, increasing food production in many countries.
- The utilization of fertilizers and irrigation is a critical part of this technology.
Impact of Green Revolution
- The Green Revolution substantially increased global food production.
- It mitigated the threat of starvation in several countries, such as India and China.
- The Green Revolution faces criticism, which focuses on significant environmental consequences.
- Increased dependence on pesticides and fertilizers.
- Limited crop diversity is another consequence of the shift to high-yielding varieties.
Food Supply Chain
- The food supply chain involves various stages, from farm production to consumer consumption.
- This chain emphasizes relationships between farmers, food processors, distributors, retailers, and consumers.
- Considerations of cost and global perspectives are also involved in the food chain.
Commercial vs. Subsistence Agriculture
- Commercial agriculture is characterized by profit maximization, while subsistence agriculture prioritizes household needs.
- Farmers in both types of agriculture adapt to challenges, including changes in climate, environment, and policies.
- The varying degrees of involvement in each sector are a clear indication of globalization.
- Governments and international organizations hold considerable influence within the agricultural sector worldwide.
Global Food Chain
- The global food system is greatly impacted by responses to genetically modified crops.
- These crops are used to improve agricultural output and provide sustainable solutions.
- Transitioning to sustainable farming practices acts as a significant challenge for the food system today.
