Q

Nutrition Transition Model (5 stages)

A
  1. Hunter gatherer - wild plants, labour intensive, lean, high disease, low fertility, low life expectancy
  2. Settlements begin, famine emerges - cereals dominate, labour intensive, stature decline, high fertility
  3. Industrialization, reducing famine - starchy, low variety, low fat, high fibre foods. labour intensive, disease and stunting, slow mortality decline
  4. Non-communicable diseases - eat fat, sugar, processed foods and caloric beverages. Technology, work, leisure. Obesity emerges, accelerated life expectancy. Higher disability period.
  5. Desired societal/behavioural change - more fruit, vegetable, fibre, water. Less fat, Doric beverages. Replace sedentary lifestyle (no movement) with purposeful activity.

Q

Causes of world hunger (2)

A
  1. Distribution of food - commercial farmers sell to the highest bidder + wheat often goes to cattle farmers
  2. Agribusinesses and large corporations - persuade subsistence farmers to switch to commercial farming of non-food crops (crop substitution)

Q

Why are there disparities in access to food for LIC? (4) Think about the traditions…

A
  1. Subsistence farming and tradition farming methods (less productive)
  2. Poor storage facilities (insects and pests)
  3. Absentee landlords (charge excessive rent making farmer trapped in cycle of paying off debt)
  4. Divided landholdings (many small pieces of land are split among the children of a dead landlord)

Q

Epidemiological transition stages (3)

A
  1. Era of pestilence and famine - high death rates, low avg life expectancy, high incidence of contagious diseases (HIV, tuberculosis, Leprosy)

24
Q

Why aren’t food miles entirely accurate?

A
  • Doesn’t consider quantity or vehicle used to transport food
  • Increased energy use and carbon footprint with local produce (sometimes)
25

A
  • poorer farmer rely on climate (ex. Water supply is rainfall)
  • richer farmers can change the microclimate (ex. Irrigation)
26

  3. Eliminate mosquitos by filling in irrigation, introducing fish that eat the parasite
  4. Time-distance decay
35
Q

How does diarrhoea spread? (3)

Q

What is the aim of an agribusiness?

A

To farm large areas of land using a high rate of mechanization to minimize labour needs and maximize profits.

37
Q

Vertical integration

A

One firm controls most or all stages of production (TNC can declare profits in country with lost ax rate and avoid large mark ups)

38
Q

Horizontal integration

A

One corporation controls several firms within the same industry (monopoly)

39
Q

Consolidation and why it is harmful for smaller companies AND people

A

Smaller companies acquired by larger TNC’s to gain customers

—> threatens viability of commodity farmers. Cheaper and more accessible for poorer people. Health problems.

40
Q

Food sovereignty

A

Right of the people to have healthy and culturally appropriate food produced through own sustainable agriculture and food

  3. Processed foods are more affordable and available
  4. Dietary adaptation - more processed, refined, and branded
  5. Fast food chains, restaurants, supermarkets (more convenience)
  6. Obesity and malnutrition - poor quality and cheap
42
Q

Why do more females experience malnutrition? (1 A-D)

  5. Political instability and conflicts - displaced people, terrorism, kidnapping
  6. Mass migration
46
Q

Economic solutions to food insecurity (2)

A
  1. Micro finance - loans given to small-scale farmers (high interest rates + high risk)
  2. Grow crops for human consumption rather than industrial raw materials (even though lower profits)
47
Q

Management solutions to food insecurity (4)

A
  1. Crop substitution - require less water
  2. Raising farm productivity - education, better resources for female farmers, better seeds and fertilizer
  3. Expand commercialization
  4. Reduce food waste (storage facilities, vermin, bad preparation and management)
48
Q

Technological solutions to food insecurity (4)

A
  1. Expand irrigation
  2. Improve transportation (railways, roads)
  3. Improve service infrastructure - electricity to farmers, radio, TV —> more awareness on farming policies + make better choices about crops
  4. Expand mechanization
49
Q

Political solutions to food insecurity (7)

A
  1. Food aid - weakens long term food security and self sufficiency
  2. Free trade - threatens local food producers
  3. Fair trade
  4. Land reform - amalgamate fragmented farms
  5. Planning - gov
  6. Population control
  7. Peace - instability distrusts transportation and distribution networks + discrimination
50
