Food Production Flashcards
what is arable farming
the cultivation of crops e.g. wheat farming
what is pastoral farming
rearing livestock e.g. beef
what is commercial farming
growing crops or rearing livestock to sell for profit
what is subsistence farming
growing crops or rearing livestock to feed the farmer and their family
what is extensive farming
a farm with low inputs or yields per hectare
what is intensive farming
a farm with high inputs or yields per hectare
what is nomadic farming
farmers move seasonally with livestock to different areas
what is sedentary farming
the same area of land is farming year after year
6 physical factors influencing type of agriculture
- temperature - optimum temperature for crop growth
- growing season - the length of growing season affects the type of crop grown e.g. barley needs about 90 days from sowing to harvest
- precipitation - water is required for crops to thrive
- relief and slope aspect - the altitude of the land affects temperature and the steepness affects the suitability for crops. different crops may be grown on south-facing slopes which get more sunshine and are warmer
- soil type and fertility - crops need deeper, more fertile soil
- drainage - for most crops to grow the land needs to be well drained so that roots do not get waterlogged
6 human factors affecting agriculture
- tradition - many farms simply grow the crops or raise the livestock that have been on the farm for generations
- subsidies - farmers may change crops or livestock depending on the money available from the government
- transport - the cost of transporting the product may affect what is produced
- farm size - larger farms can afford more in terms of feed, fertiliser and machinery
- market demand - the changing demand for produce. increased demand for meat may affect the choice of what is produced
- capital - the amount of money a farmer has to invest
3 physical inputs to farms
- climate
- soil
- relief
5 human inputs to farms
- subsidies
- machinery
- labour
- pesticides/fertiliser
- seeds
8 processes in farms
- ploughing
- milking
- sowing
- shearing
- pest control
- fertilising
- harvesting
- feeding
8 outputs in farms
- cereal
- crops
- hay/straw
- milk
- meat
- manure
- eggs
- vegetables
5 impacts of farming systems
- monocultures reduce diversity because the animals have no access to a wide range of foods
- when nutrient cycling is often dependent on fertilisers added to the soil, this may be natural (manure) or artificial fertilisers
- when the ecosystem is modified with inputs of seed, fertiliser, pesticides, herbicides and the use of machines
- where food webs are reduced
- reducing the amount of biomass
5 natural causes of food shortage
- flooding- crops cannot cope with being waterlogged
- causes the death of livestock - drought and unreliable rainfall. this can reduce crop yields significantly
- disease - reduce yields, result in livestock deaths/culling e.g. swine flu
- pests - locusts can wipe out entire fields of crops in a matter of hours
- tropical cyclones - heavy rainfall and strong winds which can destroy large areas of crops
7 human causes of food shortage
- war and conflict - people are unable to farm due to the conflict. war also disrupts the supply and movement of food supplies
- rising food prices - people cannot afford the food that they need
- human-induced global warming - this leads to changing weather patterns, increased temperatures and rising sea levels
- lack of investment - many LEDCs have poor transport systems which means that transporting food and livestock is difficult
- corruption- investment in rural areas and agriculture does not happen due to corrupt politicians taking the money
- rapid population increase - the food available has to be shared between more people, decreasing the amount that people have
- soil erosion and desertification - overgrazing and over-cultivation lead to a loss of soil fertility so plants won’t grow, or yields decrease
6 impacts of food shortage
- malnutrition
- rising food prices
- underdevelopment - loss of productivity
- soil erosion and desertification
- social unrest
- migration
8 solutions to food shortage
- appropriate technology
- educated farmers
- green revolution
- GM crops
- food aid
- fertilisers/pesticides
- mechanisation
- irrigation
5 causes of food shortage in Somalia
- Al Shabaab - terrorist group in Somalia mean aid can’t get to certain areas and they use food as a weapon to control and recruit
- suffering from a two year drought
- already existing levels of malnutrition
- drought kills livestock and agriculture (90% animal mortality in some areas
- lack of action from the government - $1 billion required, less than $200 million raised
7 impacts of food shortage in Somalia
- 2/3 of those displaced dont have access to clean water
- 4 million suffering from hunger and malnutrition
- death by starvation
- loss of livestock and crops
- high inflation of food prices, which many can’t afford
- poverty, leading to physical and mental health issues
- migration across the border into Ethiopia
Bangladesh case study: 6 inputs
- rich alluvial soils full of nutrients due to annual flooding of river ganges
- manure from water buffalo adds fertility
- large population–> high labour input
- land to grow and relief
- climate - plenty of rain and high temperatures
- water availability
bangladesh case study: 5 processes
- rice initially grown in nurseries, then transported as soon as monsoon rains flood fields
- animals used for ploughing instead of machinery
- fish added to padi to add protein to diet and fruit trees
- low walls built to keep water in the padi fields
- sowing, weeding, planting, harvesting
bangladesh case study: 6 outputs
- During the dry season, when there is often insufficient water for rice, either vegetation’s or a cereal crop is grown.
- farmers grow vegetables on small land plot
- rice
- money from selling
- family consumption
- new investments in irrigation
