Study Notes
Food Security and Agricultural Challenges
- Food Crisis: A food crisis occurs when a country lacks sufficient food to nourish its population.
- Food Insecurity: The state of not having reliable access to enough food.
- Food Deficit: When food supply is short to meet demand.
- Food Security: The reliable access to enough food to meet nutritional needs.
- Food Self-Sufficiency: Producing enough food domestically to meet the country's needs; not relying on imports.
Farming Practices and Types
- Farming Process: Includes input (e.g., land, rainfall, labor, machinery), process (e.g., sowing, ploughing, fertilizing), and output (e.g., crops, livestock ).
- Extensive Farming: Requires less labor, capital, and machinery per unit of land.
- Intensive Farming: Requires higher labor, capital, and machinery inputs per unit of land to increase yield.
- Arable Farming: Focuses on crop production only.
- Pastoral Farming: Focuses on livestock production only.
- Mixed Farming: Combines crop and livestock production.
- Subsistence Farming: Production for family consumption.
- Commercial Farming: Production for sale.
- Low Technology Farming: Utilizing animal power and primitive tools.
- High Technology Farming: Employing more machinery, irrigation systems, and chemicals (e.g., genetically modified crops).
Agricultural Inputs and Outputs
- Physical Inputs: Natural resources like land, rainfall, and sunlight.
- Human Inputs: Man-made resources like labor, machinery, and irrigation.
Climate and Geography influencing Farming
- Climate and Geography: Factors like rainfall, temperature, growing seasons influence agricultural output.
- Northeast China: Extensive flat land, suitable for mixed arable and pastoral farming.
- Northwest China: Plateau (highlands), low annual rainfall, suitable for pastoral farming .
- Southeast China: High annual rainfall and temperatures, suitable for arable and mixed farming all-year round.
- Middle of China's Basins: Subtropical climate; suitable for both farming and pastoralism.
- East China: Flat plains, fertile soil, alluvial soil, repeated flooding; suitable for arable farming.
Challenges to Food Production
- Major Farming Problems: Weather challenges: typhoons, flooding, water shortages create crop failure and hinder yields.
-
Human Constraints:
- Urban encroachment: Arable land conversion into urban areas reduces available farmland.
- Polluted Farmlands: Contamination from factories, towns, and domestic sewage affects productivity of land directly, reducing arable land, and reducing the carrying capacity of the environment.
- Rural Population Decrease: Fewer workers in agriculture leads to reduced output. Reduced workforce means fewer people to operate the land for farming, causing a reduction in output.
- Carrying Capacity: The maximum population an environment can sustain while maintaining the quality of the land and water.
- Overcultivation: Intensifying farming beyond the carrying capacity reduces soil fertility and productivity, leading to reduced output over time and causing the long-term decline in food production.
Impacts of Food Production Changes
- Land Degradation: Reduced soil fertility, decreased productivity, and reduced arable land, due to over-cultivation result in lower output.
-
- Food Production Decrease: Declining arable land, overcultivation coupled with decrease in quality soil, reduced workers in agriculture reduces the overall food production.
