Food issues

ARABLE FARMING

- the growing of crops, usually on flatter land

PASTORAL FARMING

- the raising of animals, usually on land that is not used for arable farming

MIXED FARMING

- the growing of crops and rearing of animals

- this is used on a commercial scale across developed countries

SUBSISTENCE FARMING (EXTENSIVE)

- growing and providing food only for the farmer and his family

- sometimes food is produced for the local community

- there is no surplus

- labour intensive, amount of capital input is low

COMMERCIAL FARMING (INTENSIVE)

- large scale, profit making farming

- very high yields per hectare

- commercial farms often grow just one type of crop/rear one type of animal

- amount of capital input is high, labour input is low

Advantages of the green revolution

• more crops of different varieties being produced resulting to increase in yeilds.
• its decreased the number of human labour and it has increased employment in industries. 
• Advantage to farmers: this includes their economic situation improving, even small and marginal farmers (although they were late in joining) getting better yield, control on many insects and pests, mechanizing improved working conditions
