Q

Why are emerging MIC adopting Western diets? (4)

A
  • rising income gives access to energy dense foods

Q

What is the distribution of oil around the world? (Large production and consumption)

A

Middle East, Brunei, Kuwait have small populations with large reserves of petroleum. Thus, lots of money. Japan and France are large buyers (make money through manufacturing, then buy oil)

  • can last more than 200 years with the current rate of consumption.
23
Q

Controversies/cons surrounding nuclear power plants (3)

A
  • radioactive wastes (accidents, leakages)
  • high upfront cost
  • stolen to create weapons or sold to terrorist organizations
24
Q

How can we use biomass and where is it a significant energy source? (2)

A
  • burning fuelwood
  • highly significant in LIC
  • can burn human sewage for fertilizer and fuel.
25
Q

Pros of hydroelectricity (1)

A

-low cost to obtain power

26
Q

Environmental concerns with hydroelectricity (4)

A
  • drowns river valleys
  • heavy water causes earthquakes
  • sedimentation build up causes erosion
  • destroys vegetation and animal habitats.
27
Q

Cons of wind power (2)

A

  • ruin scenic beauty
28
Q

Cons of using solar power (1)

A

29
Q

What are the relationships between the water-food-energy nexus?

A

Water-food
Water needed to grow food, water used in food transports (virtual water)
Food-energy
Energy used to produce food, food used to produce energy (biomass)
Water-energy
Energy needed to supply water, water needed to generate energy

30
Q

security definition

A

Availability and reliability of ________ (water/energy/food)

31
Q

Why is there an increasing demand for resources?

A

Increase in the world population, with increasing affluent global middle class.

32
Q

How do big countries (like China and South Korea) offset their lack of food security due to large population and less land? How is this problematic?

A

Invest in farmland in low-income countries, then export food. Deprives the host country of food supplies (increasing their food insecurity) and increases water insecurity by exporting embedded water.

33
Q

How does climate change affect the water-food-energy nexus? (3, one for each aspect)

A
  • More droughts —> water insecurity
  • More intense rainfall, extreme weather —> food insecurity
  • Renewable energy is impacted by changing patterns of precipitation
34
Q

How do the rising temperatures in Albania affect the food security?

A

Farming productivity decreases, rain-fed crops fail.

35
Q

Why did GHG emissions in Albania decrease after the fall of the Soviet Union?

A

Closed inefficient, uncompetitive power plants and factories. Encourage better farm management systems

36
Q

How is Albania fit to deal with climate change (less vulnerability)

A
  • strong administrative and political institutions
  • foreign investment
  • national plan to address threats of climate change (with reference to WFE nexus)
37
Q

What are the impacts of climate change (increasing temp) on Kyrgyzstan?

A
  • impact on basic food crops (wheat, barely, sugar beet, maize) bc no irrigation (irrigation system disintegrated through lack of maintenance after fall of Soviet)
38
Q

Why is Kyrgyzstan vulnerable to climate change? Specifically what is wrong with it’s government.

A

Poor country, political institutions poorly equipped to deal with climate change.

39
Q

Recycling definition and how is it often used in rural areas

A

Process of converting waste into useable material (common in rural areas where food scraps turn into livestock feed which turns into fertilizer - subsistence farmers)

40
Q

Why are there more electronic wastes in the world? (3)

A
  • growing global middle class
  • cheaper electronics, more accessible and affordable for low income
  • companies encourage consumers to discard older appliances for new ones
41
Q

Why does Agbogbloshie in Ghana exist (HIC waste go to LIC) and what do they do there?

A

Recycle e-waste because it is difficult to recycle near HIC due to environmental regulations. They burn cables, plastic to extract precious metals. Can be sold or thrown into landfills.

42
Q

How can we reduce e-waste? Strategies by companies.

A
  • Take-back systems where apple takes back old phones, robots disassemble and sort items, then sells materials
43
Q

Hard conservation definition

A

Completely prohibiting any adverse human impact (ex. Protecting endangered animals and fragile ecosystems)

44
Q

Soft conservation definition

A

Allows resources to be used but insists on NO WASTE (ex. Fishing quotas, must return all female fish)

45
Q

What are pros of a circular economy? (2)

A
  • restores and regenerates
  • maximizes value and efficiency
46
Q

What are pessimistic views towards population and resource consumption trends?

A

neo-Malthusian views: non-renewable resources are finite and therefore exhaustible. Population growth needs to be controlled or else pressure on scarce resource will cause widespread deaths through famine, disease, war.

47
Q

What are optimistic views towards population and resource consumption trends?

A

Esther Boserup: more people mean more food because people are productive resources. (Every consumer is a producer)
- with more population, farmers feel pressure to improve productivity, be more inventive. (Scarcity drives innovation)

48
Q

Stewardship definition (like resource stewardship)

A

Ethical principle that views managing resources as a responsibility undertaken as a privilege on behalf of others. Resources are managed with the needs of the wider community in mind, taking into account resource availability for future generations. Sustainability!

49
Q

How can we design items to encourage sustainability and reusability?

A

Design items to be disassembled at the end of their product life, can be reused or repurposed. Extends resource lif.

50
Q

What 3 aspects are the circular economy based on? Like what is the goal/aim for the future (ideal)?

A
  1. waste no longer exists, everything is reused, redistributed, refurbished, or remanufactured.
  2. consumable and durable components of products separations (biological things can be returned to biosphere) durable resources can be recycled.
  3. Infinitely renewable energy used (more resilient system, less dependence on fragile finite resources)
51
Q

How do the SDG’s help make the world a more sustainable place (together?)

A

More integrated and holistic system (systems thinking, circular economy, considers everything)

52
Q

Name 3 SDGs.

A

End poverty, end hunger, good health and wellbeing, quality education, gender equality, clean water and sanitation, affordable and clean energy, decent work and economics, sustainable cities and communities, climate action, peace justice and strong institutions…..

53
Q

Why do HIC need to help LIC to achieve SDG

A

LIC lack financials and organization, require support from HIC.
