Consider them modified ecosystems
Show inputs, processes, outputs

Can compare with productivity, biomass, energy efficiency

32
Q

What is the energy efficiency ratio (EER)?

A

Measures amount of energy input compared to output

Agro-forestry / hunter-gathering is higher than intensive pastoral farming
Seen in nutrient-cycling diagrams and energy flows

33
Q

What is a water footprint?

A

Measure of how much water is used in human activities

34
Q

What is the food availability deficit (FAD) and food entitlement deficit (FED)?

A

FAD: food shortages from lack of food, less accepted
FED: food shortages from lack of access

Type of food consumed depends on price, health, taste; income / education influences choice

35
Q

Describe case study: food consumption in Cape Town, South Africa

A

End of apartheid → more black Africans in urban areas → western diet → obesity / diabetes

Perception of food varies by gender and age; income effects food quality

36
Q

Describe case study: food consumption in the Middle East

A

Subsidies negatively effected consumption
Change after increased oil revenue
Religion / preferences / discrimination
Mass media and migration

37
Q

How / where does obesity effect children?

A

Weight and calorie intake has increased
Obesity levels higher in low-income families → financial health burden
More food → more expensive → big industry
Poor nutrition also causes stunting

38
Q

What is disease diffusion?

A

Spread of a disease from the original source
Frictional effect of distance / distance decay: closer places more and sooner effected
Infectious disease is an S curve (time vs cumulative percentage of adopters)

39
Q

What is expansion diffusion?

A

Expanding disease has a source and diffuses geographically outwards

40
Q

What is relocation diffusion?

A

Spreading disease moves, leaving origin / source

41
Q

What is contagious diffusion?

A

Spreading disease through direct contact with infected individual

42

Spread through sequence of classes / places (city → large urban area → small urban area)

43
Q

What is network diversion?

A

Disease spreads via transportation and social networks

44
Q

Describe the Zika virus

A

Misquito-borne + sexual contact → relocation diffusion from travel in South America mostly
Causes birth defects and neurological problems

45
Q

Describe malaria

A

Life-threatening, parasite transmitted by mosquito; high global risk

Mosquito prefers humid tropics → agricultural areas and refugee camps from natural disasters or war

Very expensive (global and individual) → prevention is cheaper
Some people more at risk

Prevention via vector control: insecticide-treated nets, indoor residual spraying

Insecticide and drug resistance is problematic

46
Q

Describe cholera

Waterborne disease via water, food, poop
Usually not severe

To occur must: breaches of water sanitation, present cholera

High-risk for < 5, overcrowded camps of displaced people

47
Q

A

Significant portion is malnourished
Global population grows
Climate change threaten production
Food system itself contributes to climate change / env harm

48
Q

What is the UN Food and Agriculture Organization (FAO)?

A

Aims: eradicate hunger, food insecurity, malnutrition; eliminate poverty; sustainable use of natural resources; increase peoples’ resiliences to threats and crises

49
Q

What is the World Food Programme (WFP)?

A

End global hunger via good assistance to poor and most vulnerable
Objectives: save lives / livelihoods in emergencies; support food security and (re)build livelihoods after emergencies; reduce risk and promote self-sufficiency; reduce undernutrition and break generational hunger

50
Q

What is the impact of government food subsidies on the food system?

A

Subsidized agriculture in high-income countries drives down global prices → maintain poverty in low-income countries
Developing countries have created their own subsidies now

Subsidies → overuse fertilizer / pesticide

51
Q

What is the EU Common Agricultural Policy (CAP)?

A

1962: 1 market in EU, preferences to EU-grown products, financed by members
System of guaranteed prices → self sufficient in many sector
Led to intensification (increased inputs and outputs), concentration (specific product production confined to particular areas), specialization (specialize in concentration)

Reformed in 1992 because of surpluses

52
Q

What are non-governmental organizations (NGOs) in food?

A

Deliver food to those with insufficient access
Mostly low- and middle-income countries

53
Q

What is the UN‘s World Health Organization (WHO)?

Building sustainable institution
Assess and monitor health trends

Many initiatives (tuberculosis, malaria, etc)

54
Q

How is health care in low- and high-income countries different?

A

High-income: technology, curative, private
Low-income: low-tech, preventative primary care

Those who can access don’t need it and vis-versa

55

Founded in 1971 to provide emergency medical aid
Over 70 countries with mostly local medical experts and other professionals
90% funded by private donors, otherwise corporate

Provides assistance in Sudan, Europe vaccination programs, malaria, etc

56
Q

What is glocalization?

A

Adapting a global product to a local market

57
Q

How do TNCs effect traditional food consumption?

A

TNC “big food” is ultra-processed, unhealthy, and displacing traditional food systems
Main interest is to make money

Market penetration plateaued in high-income countries → “health’’ convenience food
Increasing market shares in LICs

58
Q

What is a global value chain (GVC)?

A

Analyzes role of “lead firms” in global industries, interaction with local companies

Countries are at different levels of connection to the world economy, linked in food production

59
Q

What are two examples of glocalization?

A

McDonald’s: 2000 introed regional dishes, salads, 2006 added nutritional info

PepsiCo: Sabritas in Mexico with chili flavor, duck flavor in China

60
Q

Describe case study: changing diet patterns in Brazil

A

Traditional: varied diet (rice, beans, spices), home-cooked meals

Lifestyle change (urbanization) → more convenience food

Generally now is worse because of TNCs, more snack food

61
Q

What is the role of women in food production in low-income countries?

A

Men grow field crops
Women grow, prepare, cook food and rear livestock
Women ~half of food-production workforce in SE Asia and sub-Saharan Africa, often unpaid

62
Q

How does sexism / discrimination effect food security?

A

Women are 60% of world’s hungry
Discrimination in education / employment and in households
Less access to land, training, tech, finances, etc

Tend to be responsible for food / children: equality → ending malnutrition
Child’s chance of survival increases 20% if mother controls budget

63
Q

What are seven positive effects of closing the agricultural gender gap?

A

If women had the same resource access, yields increase 20-30%

Women’s education access effects family levels of nutrition

Training women in hygiene and sanitation immediately improves household health

Lack of land access → only subsistence farming

Diseases → greater caretaking role → less time and energy for food

Lack of financial services → limited food security and innovation

Often denied selling produce to engage in cash economy

64
Q

What is the “double burden”?

A

Women join workforce and act as caretakers at home
General household, children, other dependents

Impact of growth of elderly population is disproportionate to women
“Sandwhich generation” cares for their children and parents

US: women live longer, but less access to funds / pensions
Reduce work hours, pass-up promotions, etc to care for others

65
Q

What eight factors effect the severity of a famine?

A

Length / severity of drought
Governance
Media: attention to hazards, fundraising
International aid
Population growth: especially from refugees
Unemployment and entitlement to food
Civil unrest
Access to land and production

66
Q

Describe case study: famine in Ethiopia

A

Lots of famines, recently 2015-2016 when seasonal rains didn’t tell
> 18 million needed aid

Early-warning system → govt made social-security net, diverted money for aid
90% reduction in yields; famine caused by industrial farming “land grabs”

International donors distracted by Syria, still there are orgs helping

67
Q

What are four short-term measures for food insecurity?

A

Increase production, reduce set-aside: high market prices → more production

Food aid

Seeds and fertilizer: plant for next season given high prices

Export bans from countries with shortages

68
Q

What are two medium-term measures for food insecurity?

A

Free trade: reduce US subsidies and EU protectionism helps poor in the future; directly would increase prices in developing world

Biofuels: food crisis causes backlash against plant-based fuels, still made though

69
Q

What are three long-term measures for food insecurity?

A

Agricultural investment: African yields could increase fourfold with help

GM crops

Sustainability: rethink western lifestyles and expectations

70
Q

Describe case study: addressing food insecurity in Bangladesh

A

Food insecurity effected by international trade, land scarcity, need to increase nutritional food, natural hazards, climate change

Improved food security by increasing rice production with irrigation and high-yield varieties
Investments in rice storage, cold-storage, transport

Nationally it’s gotten better but many people are still insecure

71
Q

How does food get wasted?

A

HICs: 1/3 thrown away, mostly from consumers
LICs: 80% wasted before market, mostly at farming-producing end

Efficient practices and storage → food reaches customers
Supermarkets reject edible food bc of marketing standards
More waste of fruits and veggies than grains

Annual loss of 180 million tons

72
Q

What is genetically modified food?

A

Adding traits to a plant to make it more nutritious or resistant to disease / pesticide
> 90% of US corn, soy, cotton is GMO

Herbicide tolerance doesn’t increase yield or profit, weeds are easy

Growth is slowing, one reason is saturation

73
Q

What is vertical farming?

A

Grow year-round in high-rise buildings
Reduces transportation, any weather, no herb- or insecticide

Japan is leading bc Fukushima
Conserve water, soil-free, LEDs like sun
Uses natural light, but lots of electricity

74
Q

What is in-vitro meat?

A

Cultured meat or synthetic meat
Never been part of a living animal, grown in a lab, can add nutrients
Extremely expensive

Significantly fewer environmental impacts than normal beef
Less land, fewer GHGs

75
Q

What is preventative versus curative treatment?

A

Preventative: cheaper, policy / lifestyle reducing risk of disease

Curative: expensive, treat diseases

76
Q

How are pandemics managed?

A

Most have coordinated effort across global communities

77
Q

Describe case study: the diabetes pandemic

A

Chronic, lifelong condition effecting all ages, races; causes other major issues
Hormone insulin doesn’t control blood-sugar levels like it should

Some low-expenditure solutions (blood sugar / pressure control) in LICs
More sophisticated care in HICs with lifestyle management

Type II risk factors: obesity, physical inactivity, diet, increased affluence

Large economic burden from direct medical costs, indirect costs (morbidity, productivity), intangible costs (reduced quality of life)
