Q

Give three physical reasons for global distribution and why

A
  • Relief and landforms
    The shape and elevation of the land affects the accessibility, soil quality, drainage and natural hazards of an area
  • Climate and weather
    Temperate climates with stable weather conditions are more attractive for settlements
  • Soil types and quality
    Volcanic areas can be highly attractive due to the fertile soil and resources and minerals (sulphur, gold, diamonds etc.) brought to the surface for economic activity
    and flat land is attractive for building settlements and easiest for agricultural activities

Q

Name two contrasting examples of an uneven population distribution and explain them

A

France- 67 million
People live in Paris or on the coast/near other major cities. It has a major sphere of influence pulling people to the area. Very few people live in the mountains and external migration is from elsewhere into Paris, whereas internal migration is a way from Paris to the coast

Ethiopia- 105 million
People live near the mountains (cultural factors) and the capital city of Addis Ababa. To the east is dry and barren land with a little population

Q

Explain how the age/sex pyramids for Chad differ to Italy

A

-Chad
Chad’s age/ sex pyramid shows a youthful population in stage two. It has a high birth rate and a high death rate showing hardly any change to the structure over time and a short life expectancy

-Italy
However, Italy’s age/sex pyramid shows an ageing population in stage five with a very high life expectancy. This is because of a low birth rate and a low death rate causing the overall population to slow down

Q

Name the case study for a contemporary mega-city experiencing rapid growth

24
Q

What are the problems with Mumbai

A
  • There is a huge divide in wealth and poverty.
  • There is Rapid City growth creating:
    -Poverty
    -Unemployment
    -Poor sanitation
    -Lack of access to electricity
    -Limited access to healthcare/education
    -Lack of proper sewage system
25
Name three facts about Dharavi
-It is the main slum in south Mumbai -it is 2 km² wide and holds 1 million people -due to its proximity to Mumbai's financial district, there is great pressure to clear parts of Dharavi for modern developments
26
Benefits of Dharavi (3)
-Informal activities provide livelihood for lots of residents -Major recycling and pottery industries -there's a great sense of community
27
cons of Dharavi
Working conditions are poor and recycling industry can be dangerous
28
What is forced migration and name the three different types
The displacement of individuals or groups from their homes due to various factors beyond their control. -Conflict induced displacement -development induced displacement -disaster-induced displacement
29
What is conflict-induced displacement
People who are forced to move due to armed conflict such as civil wars, violence or persecution
30
What is development induced displacement
This includes people forced to move as a result of a large-scale infrastructure project for example the GERD
31
What is disaster-induced displacement
Natural disasters resulting in a large number of people being displaced
32

-Syria -Bangladesh
37
What are the push factors for people in Syria
-War -the Syrian president's political regimes have known to be against his own people in order to stay in power
38
What are the impacts of refugee migration from Syria on Lebanon (include environmental impact)
- 1,500,000 Syrian refugees in Lebanon, half of whom are children - 1/4 of Lebanon’s population are fleeing Syrians - Lebanon has suffered severe economic strain on health and education services, electricity, water and sanitation systems - humanitarian appeal has only received one-eighth of the funds - schools have been forced to provide places for up to 100,000 children Environmental impact: - clearing woodlands - burning trees - an increase in waste due to the influx of Syrians into Lebanon
39
What are the push factors of Bangladesh’s climate migration
Climate change = sea level rising = increase the level of floods = lack of food production
40
Explain the consequences of Bangladesh's climate migration
People move from the countryside into the megacity of Dhaka: -increasing population -there is an increase in waste and water pollution -lack of jobs-increase in illegal jobs -cultural tensions -an increase in cyclones due to climate change means that land is flooded therefore there is a loss in agriculture. This means there is lower food production and less reliable income. Therefore useful land is lost
41
In Bangladesh, why is it that when land is flooded it decreases the level of food production
When land is flooded salts from the sea seeps into the soil. This increases the soil salinity meaning crops cannot grow
42
What is an ageing population. Name two advantages and two disadvantages
An ageing population is a population where the birth and death rate are low, so there is a majority of people over the age of 60 Pros: -older populations are less likely to use their own transport, so less carbon emissions (from public transport) -help instil and protect older traditions/values Cons: -fewer working people to work for the dependent population and therefore a weaker economy -Older population means they are more at risk of illnesses putting a strain on healthcare systems
43
Describe the family size distribution around the world (HICs vs LICs)
HIC: - HICs have smaller household sizes due to women empowerment and therefore a lower birth rate LICs: -there are larger families found in LIC due to a lack of contraception/ women empowerment and religion
44
Name a policy relating to ageing societies
Do it for Denmark pro-natalist policy
45
What is a pronatalist policy
A policy that encourages the population of a country to increase their birth rate
46
What is an antinatalist policy

47
Name an antinatalist policy
The one-child policy, China
48
Name two ways that a country could increase their population

49
Name three ways that a country could decrease their population
-Free contraception -Women empowerment/education of women -increased costs on childcare, education, baby products
50
What is China's one child policy
It was a population control policy restricting couples to having only one child from 1979 to 2016
51
Name three advantages and three disadvantages of the one child policy
Advantage: - it reduced the population by 300 million over its first 20 years alone - the birth rate decreased to 17 per 1000 from 33 per 1000 in 1970 - the overpopulation did not increase after 2016 because people had adjusted to one child per couple Disadvantage: - there was a disparate gender ratio of 118 males to every 100 females (boys were favoured) - there was an increase in the trafficking of women into China as there was fewer women to marry - it was critised and considered morally incorrect as it restricted peoples human rights to have more children
52
Name two advantages and two disadvantages of pronatalist policies
Advantage: -more children equals a larger workforce -stronger economy Disadvantage: -do not often work because it is usually installed in a country which already has a high women empowerment, there a lower BR -incentives may be expensive
53
Name one country that has benefited from a demographic dividend
Ethiopia - due to an increase in standard of living, increasing popularity of family planning, and more girls staying in school for longer, the fertility rates are dropping significantly. This causes accelerated economic growth, as less time is put into caring for children, and more into the workforce
54
Name an organisation that installs anti-trafficking policies
