5.2b Case study Nomadic cattle grazing and Charlois beef Flashcards
What is a RWE of subsistence farming?
Nomadic cattle grazing in Namibia
What is a RWE of commercial farming?
Intensive Charolais beef production in France
What are some inputs into nomadic cattle farming in Namibia?
- Nomadic grazing moving from place to place so land
- Cattle survive on low grade natural forage
- No supplements
- Cattle die during drought as grass disappears
What are some outputs of nomadic cattle farming in Namibia?
- Meat
- Milk
- Fuel (dung)
- Owning cattle gives status in community
- Soil erosion
What are some system characteristics of nomadic cattle farming in Namibia?
- All raised outdoors and move continuously to new places to graze
- Grass to graze is naturally grown (not fed by other means)
- No genetic modification of cattle nor growth hormones
What are some environmental impacts of nomadic cattle farming in Namibia?
Less environmental impacts
–> No use of fertilizers, no impact on eutrophication
–> No fuel used for transport. All products are used to feed their own population
–> HOWEVER, does lead to soil erosion in the wild (during dry seasons the cattle compete with others and may overgraze!)
What are some inputs into Charolais beef production in France?
- Energy and fuel for food distribution
- Indoor rearing
- Food supplements
- Fertilisers to maximise grass production
- Selective breeding and genetic engineering
- Antibiotics and hormones
What are some outputs of Charolais beef production in France?
- Cheap meat
- Habitat destruction for larger fields
- Antibiotic resistance
- Eutrophication (fertilisers)
What are some system characteristics of Charolais beef production in France?
- Many are raised indoors and don’t see grass
- Any field/ grass is grown using a lot of fertilizers
- Genetic modification of cattle takes place (faster growth)
What are some environmental impacts of Charolais beef production in France?
Greater environmental impacts.
–> Fertilizers on fields can runoff into freshwater ecosystems (eutrophication)
–> More fuel and energy used in transport
–> Greater release of methane
