Q

what is the difference between the idea of a good diet in the 1930’s compared to today and WHY?

A

1930’s: beef, sugar, dairy and veg

today: fruit, veg, lean meat, seafood

different because majority of people were under-fed so a “good diet” promoted food that would cause weight gain

today people are told to avoid sugar, dairy and red meat because the majority of people are over-fed and need to loose weight/avoid health issues

Q

is there a relationship between income/education and obesity?

A

YES

  • directly related
  • inverse relationship (more money/education = u can afford better food and prolly have been taught to eat healthy)

Economic geographer in 40’s-50’s

“staple theory” : Canada’s culture, history and economy have been shaped by the exploitation and exports of main staples (fur, wood, fish, mined metals and fossil fuels)

Q

BC food production, export and import $$ relative rates (2007)

A

we produce about 3 billion $ worth of food
BC exports about 1.5 billion
BC imports about 2 billion

importing more than we export even tho we produce enough (monetary wise)

HOWEVER, pattern of production and imports very depending on WHAT TYPE OF FOOD it is

Q

% of production in dairy, meat, fish, fruit and veg (BC)

A 
dairy - 98% (we good)
meat - 75% (we mostly good)
fish - 68%  (we aight)
fruit - 42% (half of the ppl aint gettin fruit)
veg - 27% (only rich ppl gettin veg)

averaged out - BC is ~52% self sufficent

ALSO - these categories are spatially concentrated so regional self sufficiency is prolly higher/lower in each category in certain regions

Q

HOW do ppl figure out the amount of self-sufficiency in a given LHA?

A

you need to know legit estimates of local production and consumption and then u can compare these rates to find out the level of self-sufficency

HIGH prod/LOW consump : high self-sufficiency

LOW prod/HIGH consump: low self-sufficency

25
Q

what do differences between regions levels of self-sufficiency depend on?

A

population size and main agricultural product

26
Q

which food group are we very self-sufficient in on VAN ISLAND and which groups are not?

A

self sufficient: dairy

not: veg, fruit, grain

27
Q

how will local/global production be affected by climate change?

A
  • hard to exactly predict

- most likely it will effect fruit in the okanagan the most b/c of decreased water supply

28
Q

how much/from where do major sources of emissions occur?

A

doing aight in terms in emissions from ag….. in total ALL food production accounts for only 4% of BC emissions

BUT… of that 4%……….
agriculture = 33%
livestock = 50%

29
Q

where does Canada import the most fruit and veg from and WHY could this become a problem in the future?

A
  1. USA (cali) - 60% fruit, 70% veg comes from USA
  2. Mexico
  3. China
  4. Chile
  • could become a problem b/c drought in cali could possibly effect fruit/veg growth in future

(and others)

30
Q

aspects of food production with lowest and highest emissions

A

low = transportation

high = manufacturing of fertilizer, heating and electricity in greenhouses

31
Q

Health and nutrition policy makers need to take a more (term) approach in order to (what?)

A

HOLISTIC approach to food security, specifically by better understanding the dynamics of:

  • import, export
  • distribution
32
Q

Nutritionists are increasingly advising people to eat more …. ?

vegetables, fruit, grain, and fish

33
Q

in the last 20 years, Except in the case of fish, average production of grains and vegetables has….? and fruit production has……?

A

grain and veg production declined steadily over the past 20 years and fruit production has increased this is driven by wine production

34
Q

what 3 main things do you need to know in order to identify the most “at risk” regions for food insecurity?

A
  1. regional food self-sufficency
  2. if the places we import from are going to be affected by climate change
  3. vulnerability of populations to diet-related illnesses
35
Q

BC self-sufficiency % (GVFDEM)

A 
Veg 45%
Fruit 48%
Grain 11%
Meat 115%
Dairy 57%

36
Q

balanced self-sufficiency

extent to which a give LHA produces a balance of plant and animal foods to meet consumption needs of it’s population

37
Q

well balanced regions in BC

A
  • concentrated in the southwest, southcentral AND northeast part of BC

38
Q

how do we measure dietary health within a region?

A

Standardized Mortality Ratios (SMR): ratio between observed # of deaths and expected # of deaths

39
Q

regions with highest risk of food insecurity/vulnerbaility to climate change AND characteristics of these regions

A
  • most of west coast
  • most of Van island
  • diagonal from NW corner down to SE notch

CHARCTERISTICS:

  1. zero balance
  2. poor / rural
  3. low self-sufficency
  4. poor dietary health
40
Q

Where are dairy self-sufficient regions spatially concentrated in BC?

A

Fraser Valley, Armstrong, Creston

41
Q

Where are meat self-sufficient regions spatially concentrated in BC?

A

pretty evenly distributed throughout BC, tend towards the center tho

42
Q

Where are veg self-sufficient regions spatially concentrated in BC?

A

Fraser valley

43
Q

Where are fruit self-sufficient regions spatially concentrated in BC?

A

Okanagan Valley and lower Fraser valley

44
Q

What are some predictions about change to veg and fruit production due to climate change and why?

A
  • southern/interior fruit and veg production depends on irrigation from glacier-fed waterways
  • predicted that glaciers will melt and waterways will dry out in the next few decades
  • also threats from high risk of flooding in fraser valley/southern regions
45
Q

what is ironic about the relationship between meat production and climate change in BC?

A
  • meat prod. is the most resilient/largest food sector in BC

- reinforces climate change but is the least effected by climate change

46
Q

WHAT needs to be incorporated into food planning in order to slow/reverse food insecurity?

A
  1. climate change adaptation strategies (fruit irrigation plans in interior, flood pland for fraser valley, less GHG emissive dairy and meat strategies…)
  2. better infra for food production in local areas to help make them more self-sufficient and resilient
47
Q

WHAT can Van Island do to better out food situation?

A
  1. convert land used for non-food stuff into land that is used for food stuff
  2. better understand impacts of climate change on dairy production because dairy is the main sector of van island’s food system
