A

influenced by:
-nutrition
-access to health care
-environmental conditions (adequate housing, safe water, proper sanitation)

-if GOOD or IMPROVING (eg MEDCs) conditions, then DEATH RATE FALLS and VERY HIGH LIFE EXPECTANCY

-if bad/inaccessable (eg LEDCs) conditions, then HIGH death rate and LOW life expectancy, although this has begun to improve recently

46

increasing food production:

-growing crops in nutrient enriched water (hydroponics)

48
Q

Thomas Malthus

A

-suggested in 1798 that the GROWTH of human population would OUTRSTRIP ability of earth to provide sufficient food resources

49
Q

resource requirements’ influence on difficulty to estmiate carrying capacity of human populations

A

-varies according to lifestyles

-differ over time and from population to population

e.g, a Maasai herdsman uses less resources than an urban dweller in an MEDC

50
Q

Valuation of natural capital

A

-use of valuation: resources that have a price such as marketable goods, ecological functions recreational function

-non-use of valuation: resources that have intrinsic value (the right to exist), future uses (medicines, potential gene pool), existence values (Amazon Rainforest), present for future generation

51
Q

factors contributing to birth rates and fertility rates

A

-lack gender equality –> women no power or education/employment creates HIGH birth rates

-religion –> most religions pro-natal, favour large families

-high infant mortality rates –> pressure on women to have more children to offset mortality losses

-agricultural societies –> larger families to provide labour and (financial/housing) security as parents age

52

A

-recycling
-reuse
-composting
-incineration
-landfill

53
Q

Zero-waste policy

A

Aims to reduce the amount of SDW going to an incinerator to zero, with the rest of the SDW reduced (ie., never produced), never recycled, or reused

54
Q

Thomas Malthus

A

-Published essay on the principle of population

-argued that populations tend to grow GEOMETRICALLY while the resources that suppor them grow ARITHMETICALLY

-thus populations would outstrip the resources, leading to widespread, famine, disease, and war

55
Q

evaluate composting as a waste disposal method

A

ADVANTAGES
-produces fertiliser
-reduces volume of waste
-reduces use of chemical fertilisers

DISADVANTAGES
-can smell unpleasant
-requires effort and space
-can attract vermin if not done correctly

56
Q

Unsustainable use of renewable natural capital (EQUATION)

A

Use of natural income + the natural capital reserves

57
Q

importation and why it is difdfifuclt to estimate carrying capacity

A

-populations regularly import resources from outside immediate environment

-allows them to grow beyond boudnaries of local resources and INCREASE carrying capacity

-eg. import of food from Kenya to Europe

58
Q

evaluate recycling as a waste disposal method

A

ADVANTAGES (3)
-used to make new products
-maintains stocks of non-renewable and replensihable resources
-reduces greenhouse gases

DISADVANTAGES (3)
-can produce toxic waste
-can be labour intensive
-can be UNECONOMIC re supply and demand factors

59
Q

humans re carrying capacity

A

-range of resources used is much greater than any other species

60
Q

Unsustainable (in reference to populations)

A

If the ecological footprint exceeds the land available

61
Q

characteristics of areas with low population density

A

-too hot
-too cold
-too dry
-too wet

unable to support high population because cannot produce sufficient food

-however globalisation=increased trade, now possible to import resources to these areas and they can now support greater populations

62
Q

natural resource vs natural capital

A

-can be itnerchangable HOWEVER

-NATURAL RESOURCES suggests that resources are there to be USED

-NATURAL CAPITAL suggests something to be MANAGED to produce an INCOME

63
Q

Reasons EFs vary (list of 4)

A

-lifestyle choices
-productivity of food production systems
-land use
-industry

64
Q

-direct use values
-consumptive use values
-non-consumptive use values

-indirect use values
-optional use values
-bequest value

-non-use values/existence values

65
Q

Dynamic concept of natural capital

A

Whether or not something has the status of natural capital, and the marketable value of that capital varies regionally and over time is influenced of:
-cultural
social
-economic
-environmental
-technological
-political factors

66
Q

influencing factors of the EF of LEDC vs MEDC populations

A

-can be related to stages of demographic transition model

-generally an INCREASE of EF with each stage of the dtm

-very developed countries may be reducing their EF through techniques like energy efficiency strategies

-usage of resources (energy, goods, natural resources) is GREATER in MEDCs because people have moer appliances and wealth

-more transport/travel in later stages

-greater production of domestic waste

2 example countries: Afghanistan vs America

67
Q

neo-malthusian view overview

A

-called limits to growth model

-developed in 1970s, predicted limits to growth of human population would be reached in 2100

-also believes that it would be possible to change these projections

-technocentrism

68
Q

indirect use value

A

–natural capital assessment type

-derived from ecosystems services that provide benefits OUTSIDE THE ECOSYSTEM

-eg natural water filtration that may benefit people downstream

69
Q

Circular economy

A

An alternative to a traditional linear economy (MAKE, USE, DISPOSE), in which we keep resources in use for as long as possible, EXTRACT the MAXIMUM VALUE from them whilst in use, then RECOVER AND REGENERATE products and materials at the end of each service life

70
Q

carrying capacity

A

The maximum number of species, or ‘load’ that can be sustainably supported by a given area

71
Q

demographic transition model stage 1 characteristics and appearance

A

-HIGH birth rate
-HIGH death rate
-STABLE or SLOW natural increase
example society: NO MODERN COUNTRIES; considered pre-industrial stage

-shape: concave curve wide base very thin pointy top

72
Q

direct use values definition

A

-natural capital assessment type

-ecosystem goods and services DIRECTLY USED by humans

-usually valued by people visting or residing in the ecosystem

73
Q

Ecological footprint (EF) (2 points)

A

-the area of land and water required to provide all resources and assimilate all the waste for a given population

-if the EF is GREATER than the area of land and water AVAILABLE to that population, then it is NOT SUSTAINABLE

74
Q

increasing carrying capacity (energy production)

A

-use of new resources (eg shale gas)

-greater development of altnerative energy (eg solar, wind)

-increased energy conservation (home, public buildings, industry, transport)

75
Q

basic list of why it is difficult to estimate carrying capacity of human populations

A

-much greater range of resources used

-substituting

-resource requirements differ

-technological developments change resources required

-regular importation allows to grow beyond boundaries of local resources

76
Q

technological development and why it is difficult to estimate carrying capacity

A

-gives rise to continual changes in: RESOURCES REQUIRED and AVAILABLE for consumption

eg: increase in nuc power since the 1950s

77
Q

Total fertility rate (TFR)

A

The average number of children per woman living through childbearing age

78
