ENVIRO TOPIC 6.2 factors affecting food security

- six pillars

what factors affect food availability

food production, the amount of produce made by farmers can change due to diff factors

1. soil management
   - well maintained soil = plant grow good. If overused, nutrients is removed = hard for plant to grow

2. weather patterns
   - temp, rainfall affect quality and speed that plants grow

3. land use
   - can be used for urbanisation or lost to desertification

4. crop selection
   - each crop need diff resources to grow, some need specific climate as well

5. transport of food
   - cost lots to transport = food cost more. Weak transport systems reduce food availability

what factors affect accessibility

main factor = cost, generally linked to poverty

• poverty = unlikely to be able to access food, cant afford, unlikely to grow food cuz cant afford farming land

• cant afford pesticides = cant grow many crops

location - local market can be hours away only accessible by walking for some

what factors affect utilization

how its cooked affects quality & quantity of food on nutritional value

• can inc/dec. nutritional value EG. frying dec. nutritional value

• unclean water & food practices affects food safety

• lack of education on how food should be prepared

what factors affect stability

1. natural disasters + outbreak of disease
   - wipe out entire crops for the season, reducing obtainability of food

2. conflict
   - farmers flee land or fight in the conflict/war

3. food used as a weapon
   - enemies cutting of food supplies in order to gain ground in the battle

4. crops destroyed during fighting

5. food diverted to the war effort = general public have less access to food

climate change effect

global warming can have some countries in floods or droughts, some with rain or not

• high temp = hard for farmers to grow crops esp if land they use is not as fertile

• livestock dont have enough grass = theyre smaller and more expensive to produce

in Aus drought = food that we export is expensive = poorer people who could afford food cant no more
