Food Production Flashcards
Def. Sedentary Farming
When a farm is based on the same location over time
Def. Nomadic Farming
When a farm moves location from one place to another
Def. Subsistence Farming
Where crops and animals are produced by a farmer to feed their family istead of selling them on the market
Def. Commercial Farming
When crops and animals are produced to be sold on the market and make a profit.
Def. Arable Farming
Farms that grow crops from the groung to be eaten or sold
Def. Pastoral Farming
Farms that rear animals to be eaten, or produce milk, wool etc. to be sold
Def. Mixed Farming
Farms that grow crops and rear animals
Def. Extensive Farming
Farming where a relatively small amount of produce is generated from a large area of farmland. Inputs are low compared to the land are farmed
Def. Intensive Farming
Where a large amount of prodce is generated from a relatively small area of land. Inputs will be high to achieve a high yield by hectare.
Input could be either fertiliser, machines and labour.
What are the advantages of mxed farming?
- Crops can be used to feed animals
- Farmers get a variety of things to sell incase the market for one fluctuates or disappears
- If one product does not go well, others can be sold - this work is more stable
- The manure formed by animals can be used to fertilise the fields
- The farmer has work throughout the entire year, and gets money at all seasons
What are the different factors that influence farming?
- Temperature/Climate
- Growing season of crop
- Soil type
- Slope/relief of land
- Market available
- Capital (amount of money a farmer can spend on inputs)
- Technology available
- Possibly restrictive or rewarding government policy
Explain how land relief can influence farmer’s decisions
- South facing slopes have more sunshine
- Steeper areas are more appropriate for sheep farming than other types of produce as they are more resistant to the tougher conditions
- As the land gets higher, the temperature also decreases until it gets too cold to grow crops
- Flat land is desireable for crop farming as it takes less input to reshape the land and machines can be used mor easily
- It is easier to irrigate flat land
Def. Inputs
These are things that go into the farm and may be split into Physical Inputs (e.g. amount of rain, soil) and Human Inputs (e.g. labour, money etc.)
Def. Processes
These are things which take place on the farm in order to convert the inputs to outputs (e.g. sowing, weeding, harvesting etc.)
Def. Outputs
These are the products from the farm (i.e. wheat, barley, cattle)
What are the Inputs for subsistence farming in the Lower Ganges?
Not needed to be known in detail
- Large labour force
- Water buffaloes for ploughing
- Rice seeds
- Heavy alluvial or clay soils to provide an impermeable layer
- Annual floods deposit rich layers of alluvium (silt)
- Five month growing season
- Monsoon rainfall over 2000mm from June to September
- Dry time for harvesting
- Temperatures over 21°C
- 2 Hectares of flooded flat land (paddies)
- Hand tools
What are the processes needed for subsistence farming in the Lower Ganges?
- Weeding
- Harvesting
- Threshing
- Planting
- Ploughing
It takes 20000 hours to farm one hectare of land
What are the outputs needed for subsistence farming in the Lower Ganges?
- Rice
- Manure from buffaloes for fertilizing
Name 2 facts about water use for subsistence farming in the Lower Ganges
- 5000 Liters of water results in 1kg of rice
- 90% of the agricultural water in Asia is used in rice production
Why are farmers in some countries commercial farmers while farmers in the same country are subsistance farmers?
It depends on:
- The amount of land owned by the farmer
- The surplus of food that can be produced
- How close the market is
- The amount of labour available in the area
- The level of education of the workers
- The availability of capital for farmers
- The use of HYV (high yield variety crops)
What are the physical/Natural causes of food shortages?
- Drought
- Disease/pests
- Natural disasters e.g. Tropical cyclones or floods
- Soil exhaustion
What are the human causes of food shortages?
- War/conflict
- Overgrazing/over-cultivation, which leads to desertification
- Rising population
- Transport dificulties
- Low investment
What are the impacts of food shortages?
- Malnitrition, which causes dficiences such as Marasmus (lack of energy), Kwashiorkor (lack of protein), and Rickets (lack of calcium/vitamic D)
- Stunted growth in children
- Increase in food prices
What are the impacts of food shortages?
- Malnitrition, which causes dficiences such as Marasmus (lack of energy), Kwashiorkor (lack of protein), and Rickets (lack of calcium/vitamic D)
- Stunted growth in children
- Increase in food prices
What are the solutions to food shortages?
- Food aid - droppping in food in affected area via truck or helicopter
- Help with buying drought resistent seeds and fertilisers
- Education of farmers to manage land correctly
What are the physical/natural causes of food insecurity in the Sahel region?
- Repetitive drought
- Only a few weeks of rainfall per year, increasing the stakes if rain does not come
- Diseses/pests
- Climate change
- Overgrazing
- Soil erosion
