21
Q

Implications of global aging population for disease burden

A

Life expectancy in LICs is increasing due to improved economies as they tend to adopt HICS lifestyles.
Results in prevalence of diseases of affluence as opposed to diseases of poverty
Affects health systems because the government has to specify more on health care for elderly population than youngsters.

22
Q

What are inputs

A
  • materials needed to operate the farming system
23
Q

what are outputs

A

products obtained when inputs are processed

24
Q

what are processes

A

activities converting inputs–> outputs

25
Q

explain extensive farming

A

small labor and capital, low output.

26
Q

explain intensive farming

A

use a lot of capital and small input, large labor, great outputs.

27
Q

envirormental costs of increasing food productions

A
  • agro-chemicals are harmful
  • cleaning chemicals is expensive
  • air pollution (GHG from farms)
  • Major TNC produce a lot of GHG.
28
Q

What are energy subsides

A

energy sources not coming from sun (fossil fuels)

29
Q

Explain the energy effiiciency ratio (EER)

A

measures amount of energy input vs output.
- Ratio bigger than 1–> efficient

Limitations of energy efficiency ratio:
Does not include wider environmental impacts on soil quality, water resources.

Advantages of energy efficiency ratio:
Useful to examine efficient of energy used in farm system→ relevant in climate change

30
Q

What are the factors affecting energy efficieny ratio

A
  1. Climate
  2. Type of soil
  3. Topography
  4. Types of farming systems
31
Q

What is water foot-print

A

measures amount of water used in human activities

32
Q

What is food entitlement deficit (FED)

A
  • food shortages caused by humans (politics or economy) which makes it difficult for people to access food
33
Q

Improvements (physical processes) that have led to increase food production→ increasing food production:

A

Increased amount of farmland: by converting waterlogged land into farms
Increase in productivity→ due to increase land size

34
Q

Reasons for increased agricultural productivity

A

high yielding variety→ eg genetically modified crops
Mechanization→ large amount of land to be cultivated
Chemical fertilizers→ increase crop yield
Irrigation
Rising incomes→ increases demand for food and meat in MICs
Better education→ better food choices (prefer high quality foods)

35
Q

what is expansion diffusion

A

expanding disease from source outwards

36
Q

what is relocation diffusion

A

spreading disease moves into new areas , leaving behind the origin of disease.

37
Q

Contagious diffusion

A

spread of an infectious disease by contact with an individual infected.

38
Q

Hierarchical diffusion→

A

an order sequence of spreading (small urban→ large urban areas)

39
Q

Network diffusion →

A

disease spreads by transportation or social networks

40
Q

physical barriers of disease diffusion

A
  1. Distance decay–> further away the less infected
  2. Mountanous regions–> restrict migration of people
  3. Extreme climate conditions (too hot or cold)
41
Q

Human barriers of disease diffusion

A
  1. Socio-political structure–> political border +migration controlls prevent people from moving
  2. manegement: isolation (quarentine measures employed in countries)
  3. Strict laws and reglaments
42
Q

The role of international organizations in combating food insecurity and diseases

A

1. Food and agriculture organization (FAO)–Z helps eliminate hunger, insecuriy and mlnutrition
2. The world food programme (WFP)–> aims to end global hunger
3. World health organization (WHO)-

43
Q

The role of governments in combating food insecurity and diseases

A

European union common agricultural policy (CAP)

Aims to ensure that food is from high quality, safe and affordable in european countries.

  1. Viable food production
  2. Sustainable management of natural resources
  3. Balanced development of rural areas
    Five formerd objectives
    * Increase europe’s competitive agricultural base
    * Match production with demand
    * Support farm incomes
    * Protetr the natural environment
44
Q

The role of NGOS in combating food insecurity and diseases

A

**Example Oxfam international
**Charity organization that provides support in ensuring food security, gender justice and improve health in yemen
Worked with the local government to provide farmers with support to develop sustainable farming practices.
Helps refugees living in uganda with food
**Example MSF: (Medecins Sans frontieres- Doctors without borders)
**
Provides free medical treatment in conflict zones in low income areas.
Doctors are volunteered workers that provide medical services

45
Q

The influence of TNC´s (agribusiness and media) in shaping food consumption and habits

A
  • TNCS make food available in areas where there is not enough food
  • Because they sell food at a chepar price
  • No preparation needed (convenient)
  • increased lifespan of food–> the consumer will not suffer from food shortages.
  • TNCS displace tradiitional food. systems–> produce ultra procesed foods.
  • In LICS processed food by TNCS is encouraged while in HICS they have began to sell helathier alternatives (satge 5 of food transition model)
46
Q

What is agri-buisness

A

farming undertaken by large scale businesses or transnational corporations

47
Q

Factors affecting severity of famine

A

The length and severity of drought→ more severe doughnuts cause worse famines
Governance: most developing countries don’t have strategic policies to ensure food security.
The power of the media : telecasting news or documentaries of famine in a given country raises awareness and can raise funds for disaster relief.
**Access to international aid: **
**Population growth: **due to displaced people or refugees can increase famine
**Access to land and food production
**

48
Q

What are the solutions for food insecurity

A

1. Economic
* Investing in agriculture–> agricultural subsides for faarmers to increase production
* Loans–> micro-loads to rural farmers for them to invest i farming
* Seeds and fertilizers –> invest in fertlizers.

2. Political
* food aid during war/conflict
* fair tarde–> provide them with fair prices to have necessary technology.
* Fre trade–> food is cheaper because there are no tarrifs imposed.
3. Technological
* GM crops, vertical farming, in-vitro meat.

49
Q

Arguemnts for and against GM CROPS

A

for:
* Imrpove nutrient cotent in food
* Insect/pest resistant
* high yield
* Withsatnd herbicides

Against:
* unsuual taste
* make disease-casuing bacteria

50
Q

ADV +DVD of vertical farming

A

ADV:
* reduces the cost of food transport
* No specialsied equipment
* natural disasters or droughts are eliminated as potential tisks for food production.
DVD:
* requires a lot of enrgy to maintain
* high cist
* low food production

51
Q

ADV + DVD of in-vitro meat

A

ADV:
* ecological footprint is reduced
* good for envioment
* large quantities of meat are produced without GHG emissions
DVD
* unethical in some religions
* taste is noit the same
* lot of money+ science knoelege

52
Q

Difference between prevention and trreatment

A
  • Prevention: before incidence
  • cheaper
  • prevents pain and discomfort
  • encourages healthy habits
  • Treatment: after infection
  • expensive
  • investign o med care
