Agriculture -

Types -

  1. type 1
    1. Commercial - For profit
    2. Subsistence - For living — to feed the farmer and family
  2. type 2
    1. Arable - Growing of crops like wheat, rice etc.
    2. Pastoral - Rearing animals and livestock
    3. Mixed - Doing both crops and livestock in one farm is mixed
  3. type 3
    1. Intensive - High inputs or yields per hectare — chicken farming
    2. Extensive - Low inputs or yields per hectare — sheep rearing
Physical Human
Temperature - optimum temperature Tradition - Grow crops that have been on the farm for generations
Growing season - length of growing season affects type of crop grown Subsidies - may change crops based on money from the government
Precipitation - Annual rainfall affects type of crop Transport - Cost of transport [livestock is more expensive than grain etc.]
Relief And Slope - Altitude of land affects temperature + steepness affects suitability for crops Farm size - Larger farms can afford more, affecting what crops are produced
Soil type and fertility - Thin and infertile soils = more grazing, deep, fertile soils = crops Market demand - Changing demands change production
Drainage - Must be well drained for growth Capital - amount of investment affects artificial inputs

Food Shortages -

Causes -

Natural Human
Flooding - crops cannot be waterlogged or they will die War and conflict - land destruction and prevention of farming
Drought - causes death and wilting Rising food prices - people cant afford the food
Disease - causes deaths and reduced yields Global Warming - changing weather, increased temperature, rising sea levels
Pest - locusts etc can wipe out fields quickly Less investments - harder to cope with expenses, discouraging farming
Cyclones - can uproot crops and destroy land Population Increase - Less food available to the population relatively

Effects -

  1. Rising prices - Increased demand and reduced supply means higher prices
  2. Malnutrition, undernutrition — eating less food or the wrong types of food
  3. Social unrest - food shortage might lead to looting
  4. Productivity loss - workforce will be less productive
  5. Soil erosion - overcultivation of land
