Study Notes
Chapter 1: Where Does Our Food Come From?
- Most food is imported, with the Mainland being a major supplier.
- A farming system involves inputs (physical and human), processes (farm activities), and outputs (crops, livestock, residues, pollutants).
- Cash crops are sold, while subsistence crops are for farmer consumption.
- Feedback within a system includes returning resources (e.g., money used to maintain inputs).
- Intensive farming uses high inputs on smaller land areas, while extensive farming uses low inputs on large areas.
- Arable farming focuses on crops, pastoral farming on livestock, and mixed farming combines both.
- Subsistence farming provides food for the farmer, while commercial farming produces surplus for trade.
- High-tech farming utilizes machinery and fuel, while low-tech farming relies more on human and animal power.
- Key vocabulary includes arable, pastoral, intensive, extensive.
Chapter 2: Where are the Farming Activities in China?
- Xibei region: Large-scale extensive pastoral farming, producing meat, milk, and wool.
- Huabei and Dongbei regions: Large-scale extensive arable and pastoral farming, with wheat, corn, potatoes, millet, soybeans, and wool as key products.
- Huanan region: Small-scale intensive arable farming, primarily producing rice, vegetables, and tropical fruits.
- Factors affecting farm type include climate (temperature and rainfall) and relief (landform).
- Ideal temperature and rainfall conditions determine suitable crops (e.g., paddy rice).
- Mountainous western regions are naturally suited for pastoral farming, while eastern plains support arable farming.
- Best farmland is often found in eastern valleys and coastal areas due to fertile soil and sufficient water.
- Key vocabulary includes annual rainfall, climate, relief, fertile, infertile, plain, growing season, temperature.
Chapter 3: Can We Produce Enough Food for Our Growing Population?
- Food supply influences economic stability; shortages can lead to economic issues and social unrest.
- Factors affecting food demand include population size and income level. Higher incomes lead to more meat consumption.
- China's grain self-sufficiency rate is high (around 95%), suggesting sufficient domestic production.
Chapter 4.1: Why Insufficient Arable Land in China?
-
Physical limitations:
- Harsh climate in northern China (long winters, low rainfall) restrict growing seasons and crop yields.
- Uneven land relief (hilly, mountainous) limits available flat arable land.
- Soil erosion from steep slopes reduces soil fertility.
-
Human activities:
- Urban development encroaches on farmland, especially in rapidly growing areas like the Zhujiang Delta.
- Environmental pollution (air, soil, water) damages land quality (e.g., acid rain, heavy metals, chemicals).
- Over-cultivation depletes soil nutrients and moisture. Deforestation contributes to soil erosion.
- Only about 15% of land remains suitable for farming.
- Key vocabulary includes soil erosion, productivity, over-cultivation, basin, topsoil.
