Q

Issues with globalisation on the food industry

A
  • Food miles, measure of how far food has travelled. Improved transport and tech has meant food can travel further in a smaller time frame = environmental issues
  • Obesity, food consumption has changed. Increase in fast food outlets = obesity more common (E.g. China)
  • Price crisis, Global food prices are vulnerable to price shocks caused by shortages/transport issues/fuel costs/natural hazards

Q

Food miles examples

A

Avg food miles:
- Apples, USA, 10,000
- Red peppers, Holland, 62

35
Q

Altitude

A

Climate, soils and growing season all interlink and affect one another. As height increases, temp decreases, precipitation increase leading to decrease in growing season

36
Q

Aspect

A

Mountains have different directions of aspect - determining micro-climate: Crops located on south facing slopes can grow at higher altitudes than those on north facing slopes.

37
Q

Slope

A

Slope angles affect rates of erosion, soil formation and use of machinery. This is because on steep slopes soils are often thin and poorly developed = cause water logging. Whereas gentle sloping angles = less erosion and leaching.

38
Q

Political factor - Land grabbing

A

process where rich countries acquire land in poorer countries (investor countries or target countries)
Investor: may have land/water constraints but high capital (Saudi Arabia) or have specific food security issues such as very large populations (china)

39
Q

Economic factor - Transport

A

With development in transport networks = food can travel longer distance in shorter amount of time - but this creates environmental issues = increased food miles = higher emissions

40
Q

Social factor - Inheritance laws

A

cultural factors in some countries mean that farms are divided amongst siblings as inheritance = subdivide farms

41
Q

Malthus

A

Pessemist
Believes there is an optimum population - once reached war, famine and disease will occur
Without a check (famine + war) population grows at a geometric rate 1,2,4,8,16 = could lead to a double every 25 years whereas food supply increases at a limited rate 1,2,3,4 - cant keep up

42
Q

Boserup

A

Optimist
Believes countries have the knowledge, resources and technology to increase food supply in response to population growth
Growth is needed to trigger these advancements

43
Q

What is the food supply chain?

A

When food is transferred from the farms to consumer - complex flow of food produce between sites of production, processing, distribution and consumption.

44
Q

What are pinch points?

A

Places in the chain where disruption occurs - political, economic, social, environmental or technological

45
Q

What is Desertification?

A

Occurs when there is a reduction in agricultural productivity due to overexploitation of the ground.

46
Q

Human causes of desertification

A
  • Poverty
  • Demand for irrigation water
  • Changing farming practices
47
Q

How does poverty cause desertification?

A

Lack of farming investment + lack of money = force people to farm on any available land = Land is often overused = Desertification + erosion

48
Q

How does demand for irrigation water cause desertification?

A

Irrigation is in response to water shortages. Water scarcity = crops dying leading to poor farming techniques put in place
Irrigation projects are poorly managed and underfunded

49
Q

How does changing farming practises cause desertification?

A

For example: overgrazing, expansion of cropped areas = intensive = remove soil nutrients as strategies such as crop rotation is avoided

50
Q

What are the physical factors causing desertification?

A
  • Climate change
  • Soil erosion
  • Salinisation
51
Q

How does climate change cause desertification?

A

Increased drought periods and changing rainfall patterns damage soil quality and animal habitats = crops die
Causing farming practises to change (For example: land degradation)

52
Q

How does soil erosion cause desertification?

A

Removes the top layer of soil = removes the nutrients

53
Q

How does salinisation cause desertification?

A

Few plants are salt tolerant = plant dies

54
Q

What are the impacts of desertification on the ecosystems?

A
  • Reduction in vegetation leads to reduced habitat + increase competition
  • Carbon sinks are reduced
  • Biodiversity loss
55
Q

How is food production affected by extreme weather events?

A

Extreme weather events: heatwaves, droughts, wildfires
These cause more water vapour evaporation from oceans - increase water vapour - increase intense rainfall - retention of heat energy from sun

56
Q

How is food security affected by water scarcity?

A
  • Agriculture account for 68% of water drawn from bodies of water
  • Water scarcity can cause crops to die and poor farming
  • Water scarce countries import water-intensive food (lettuce)
57
Q

What is virtual water?

A

The volume of fresh water needed to make a product. Measured at the place where the product was manufactured.

58
Q

How is food production affected by volcanoes?

A
  • ash-fall = pasture lands destroyed
  • ash increases levels of sulphur in soils and lower pH levels = plants cannot grow
59
Q

How is food production affected by earthquakes?

A
  • Transport and food distribution may be disrupted by earthquake activity
  • Food stocks destroyed
  • Livestock may be killed
  • Damage to irrigation systems
60
Q

How does agriculture impact biodiversity?

A
  • Deforestation
  • Biodiversity loss
61
Q

How does agriculture impact landscape?

A
  • Hedgerow control
  • Wetland drainage
  • Increase field size
62
Q

How does agriculture impact water?

A
  • Depletion of water sources
  • Pollution by agrochemicals
63
Q

How does agriculture impact Humans?

A

Health issues
- Food shortages
- Food surplus
- Use of chemicals

64
Q

How does salinisation impact the physical environment?

A

Salinisation is the accumulation of salt in soil
Low precipitation + High evaporation = salt brought to top of soil - plants intake water and leave salt - salt layer left = toxic to plants = impacts plant growth = unstable land for agricultural use

65
Q

How does irrigation impact the physical environment?

A
  • irrigation increases rate of groundwater recharge = water table rises - brings salt to plant roots = impacts plant growth/structure
  • Water used for irrigation evaporates rapidly in dry conditions
66
Q

Impacts of irrigation salinity?

A
  • Reduced agricultural productivity
  • Lower income for farmers
  • Decline in water quality
  • Decline in natural vegetation
67
Q

How does deforestation impact the physical environment?

A

In the tropics 80% of natural forest has been converted to agricultural land
Small farmers are suffering as there has been an increase in large agribusinesses
LIDC’s rely on this agricultural support as they have no access to oil and gas therefore deforestation continous rapidly
Reduces biodiversity

68
Q

What is impacting the change of landscape?

A
  • Farm practises: Deforestation
  • Policy: EU common agricultural policy - Woodland managment, EES (environmental stewardship)
  • Climate change: Desertification
  • Power Players: TNC’s
69
Q

How does water quality and agrochemicals impact the physical environment?

A

Increase in agrochemicals = increase in environmental problems such as contamination of soil/groundwater
Only 15% of the chemical hits the target leaving the rest in the air/soil = pesticide drift

70
Q

Impacts of agriculture on water quality

A
  • eutrophication
  • leaching of nitrates in groundwater
  • contamination of aquifer
  • contamination of surface water
71
Q

What are agrochemicals?

A

A chemical used in agriculture e.g pesticides, fertilisers

72
Q

What is a health issue associated with surplus food + poor diet?

A

Obesity has now exceeded those underweight
Columbia = 41% Brazil = 36% (Obesity rate)
This can cause non-communicable diseases: diabetes and cardiovascular

73
Q

How can the use of chemicals/pesticides be harmful to humans?

A

The uses of chemicals to control plant diseases and increase production is increasing = health scares for humans

74
Q

How can argricultural trading policies ensure food security?

A

Hard for poor countries to compete in international markets
Trading bloc: An agreement to promote free trade among its members e.g EU
Bilateral trade agreements: Agreement between 2 political entities that has mutual benefits and is legally binding

75
Q

How can the world trade organisation ensure food security?

A

Provide a forum for governments to negotiate trade agreements and settle trade disputes.

76
Q

How can the appropriate aid ensure food security?

A

Food aid includes project food air, emergency food aid
This provides food for the insecure countries in emergencies and also sets up projects to prevent food insecurity

77
Q

Who are key players influencing the global food system?

A
  • Food retailers There is a dominance of global food retailers - 60% of food retailing in Latin america is controlled by supermarkets
  • Fair trade organisation exists to promote fair trade and equality in international trade
