Economic development

53
Q

Why is rising population increasing global food consumption?

A

More people require more food

54
Q

Why is economic development increasing global food consumption?

A

63
Q

How does conflict affect food production and accessibility?

A

Fighting may damage agricultural land or make it unsafe

Q

What are the negative impacts of food insecurity?

A

Famine

66
Q

How does food insecurity cause rising prices?

A

Food prices increase because demand exceeds supply

67
Q

How does food insecurity cause soil erosion?

A

People who are struggling to produce enough food may not use the best agricultural practices

68
Q

What causes soil erosion?

A

Overgrazing/over-cultivation can reduce plant cover which leaves soil exposed to wind and rain

69
Q

What is undernutrition?

A

This is when you don’t get enough nutrients to keep your body healthy which can cause development problems (stunted growth)

70
Q

How does food insecurity cause social unrest?

A

Food shortages and rising prices can cause riots and may contribute to civil wars

71
Q

What are ways to increase yields of crops?

A

74
Q

What are examples of irrigation?

A

Gravity flow
Sprinklers
Drip systems

75
Q

What are hydroponics and aeroponics?

A

Methods of growing plants without soil

76
Q

How do hydroponics work?

A

Plants grow in a nutrient solution supported by materials like rockwool/gravel/clay balls

77
Q

How do aeroponics work?

A

Plants are suspended in air and water containing nutrients is sprayed onto rocks (water drips off rocks and is used again)

78
Q

How are hydroponics and aeroponics effective?

A

Plants monitored closely and nutrients adjusted to maximise crop yield
Less water required than plants in soil
Reduced risk of disease/pests

79
Q

What is biotechnology?

A

Involves genetically engineering crops to improve production
Allows more crops to be grown in smaller areas with fewer resources

80
Q

How can GM crops be designed?

A

Higher yields
Resistant to drought, disease or pests
Higher nutritional value

81
Q

What are the ethical and environmental issues with genetically modified crops?

A

Reduces biodiversity
May disrupt ecosystems

82
Q

What is the new green revolution?

Aims to increase yields using sustainable methods

83
Q

What are some sustainable methods to increase crop yields?

A

GM crops
Crop rotation
Soil nutrient recycling
Using natural predators

84
Q

What does it mean to use appropriate technologies?

A

Choosing ways of increasing food production that are suited to local environments and the needs/skills/knowledge/wealth of people in those areas

85
Q

Uses natural processes to return nutrients to the soil so that crops can continue to be grown
Artificial herbicides and pesticides are restricted
Sell locally so less transport

90
Q

What is permaculture?

A

Aims to produce food in a way that recreates natural ecosystems in an effort to protect the soil, insects and other wildlife

91

Q

What are other ways we can make food more sustainable?

A

Fish and meat from sustainable sources

96
Q

Why is eating seasonal foods all year round not sustainable?

A

Because food has to be imported that isn’t grown locally
Transport adds food miles which isn’t sustainable

97
Q

Why is eating seasonally sustainable?

A

Means only eating food that grow locally at that time of year so reduces amount of food imported

98
Q

How can meat production be made more sustainable?

A

Feeding animals locally sourced food rather than imported food
Ensuring all edible parts of the animal are eaten

99
