Q

what are consequences of population growth in the MDV vs LDW

A

MDW: less population growth, but greater environmental consequences –> consume and pollute more
LDW: high population impacts on access to food, healthcare, water, energy, ect–> poverty and conflict?

Q

overpopulation

A

a belief that an area’s population exceeds the capacity of the environment to support life at a decent standard of living; can apply to local areas or the entire planet.
-recognition that the environment can only sustain a certain population size
-what does a “decent standard of living” mean- is that the same everywhere.

27
Q

Population Natural Increase/ growth

A

fertility rate (CBR)- mortality rate (CDR): rate of natural growth

28
Q

Population momentum

A

Countries with large populations of young people, even with declining fertility, have significant momentum and will continue to see growth for several generations

29
Q

Malthus- principle of population

A

food supply is linear
population is exponential
3 stages: food>pop; Pop=food; food<pop
2 possible solutions;
-preventive checks on population- delay marriage
-Positive checks on population: war famine, disease
either wat will decrease population

30
Q

Demographic transition theory- 4 distinct stages

A

stage 1: high (birth rate) BR; high (Death rate) DR - ~0% growth rate
Stage 2: High BR; declining DR- lots of population growth
Stage 3: Declining BR; declining DR- still see growth, but declining every year
Stage 4: Low BR; low DR- ~0% growth rate
model fits teh MDW well

31
Q

Population pyramid

A

A diagrammatic representation of the age and sex composition of a population
-age structure is determined by the relative birth and death rates of a population

32
Q

Expanding populations vs diminishing populations

A

Expanding: high fertility rates
Diminishing: fertility rates low

33
Q

pandemic

A

an outbreak of disease that is of greater scope and scale (a whole country of region or even teh world) than an epidemic

34
Q

Epidemic

A

a rapid increase (beyond what is normal) of relatively short duration in the number of cases of a disease within a population

35
Q

International migration

A

global level
ie china to Canada

36
Q

inter-regional migration

A

national/regional
ie Ontario to Alberta- doesn’t change Canadian population does changes distribution

37
Q

Inter-urban migration

A

local
Mississauga to Hamilton

38
Q

Intra-urban (residential mobility (rathe than migration)

A

local
from one house or neighbourhood to another within the same city

39
Q

Destination Countries

A

typically low natural population growth, high economic and social development
many core countries rely on migration to sustain population and economic growth

40
Q

Source countries

A

typically high natural population growth, low economic and social development

41
Q

Push pull logic: push

A

being in an undesirable place. Local economic crisis, cultural or political oppression, environmental or political crisis

42
Q

Push pull logic: pull

A

aware of a more desirable place/. Economic opportunities, family reunification, freedoms, environmental and amenities

43
Q

Push and Pull: key factor

A

the new location is better than the previous one. The degree of perceived improvement (from one location to another) influences the volume and flow of migration- perception drives behaviour.

44
Q

3 main forms of push and pull logic

A

-economic: consequence of difference in wages. A threat to survival exists due to inadequate food supply, shelter, ect
-political/Cultural: Threat to survival due to political or religious beliefs. A desire for a different way of life
-Environmental: movment that results rom difference in local/regional environment conditions ie pollution, weather, ect.

45
Q

The Ravenstein Laws

A

A series of generalization drawn from observation of migration behaviour as illustrated in historical census data
-most migrations are of short distance
-Migration usually involves several intermediate steps
-more men migrate internationally than women- most migrate when adults (now no difference b/w sexes)
-Intra-regional migration usually rural to urban migration
-migrants are usually drawn to the largest centers of economic activity

46
Q

Free (voluntary) migration

A

migration from one country to another- ie family reunification
threatened by immigration laws
much migration today takes place within rather than b/w countries

47
Q

Forced migration

A

long history associated with slavery
-not all forced migrations are because of slavery- consider Indonesia- needed to move people to a less populated island

48
Q

Impelled migration

A

movment where choice is limited- not forced but also not free- ie in face of persecution, famine ect.

49
Q

Illegal migration

A

migration in violation of local immigration laws, or continued residence beyond permissible period. Illegal immigration is a major political issue.

50
Q

Refugee

A

an individual forced to flee their home country in the face of persecution (religious, ethnic, political, ect) or other threats to safety such as war, natural disaster or political instability.
many definitions
international refugee convention: someone who is unable or unwilling to return to their country of origin owning to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion.

51
Q

key distinction between migration and refugee

A

choice
-many migrate because their homes have become dangerous or difficult to live in, as they may be fleeing unrest, famine, drought, or economic crisis, but unless they are in direct danger of conflict or persecution they are not considered refugees.

52
Q

Internally displaced person (IDP)

A

an individual forced to flee their home on the face of persecution (religious, ethnic, political, ect) or other threats to safety (war, natural disaster, political instability, ect); unlike a refugee they do not leave their home country.

53
Q

refugee make one of 2 “choices”- short and long term migration

A

short term (and local) move until domestic circumstance change
A permeant (long distance) move for a better life

54
Q

Voluntary repatriation

A

where refugees voluntarily return home. This is not possible for many since circumstances on their homeland have often not changes

55
Q

Local settlement/integration

A

settlement in a neighbouring country . Neighbouring countries often face similar issues and so offering settlement is often a serious problem and burden

56
Q

Resettlement

A

The acceptance by more distant countries of refugees. Many countries are reluctant to accept refugees, presently only about 20 countries regularily do so.

57
Q

medical geography vs health geography

A

medical (traditional): the study of the spatial contect of disease
Health (today): the study of the spatial context of health and wellbeing
difference: traditional- health= the absence of disease (WHO)
not: a state of complete physical, mental and social well-being

58
Q

The 4 D’s of health geography: Distribution

A

the spatial arrangement of health and disease within an area
ie malaria, cholera- broad street pump

59
Q

the 4 D’s of health geography: diffusion

A

the spread of health and disease over space and throguh time
ie diffusion of cholera in north america in 1832 and 1866

60
Q

the 4 D’s of health geography: Determinants

A

Factors affecting health status
eg income, behaviour, social environment, physical environment, genetics

61
Q

the 4 D’s of health geography: delivery

A

the provision of health care services
eg public vs private, traditonal vs ancillary, ec

62
Q

healthcare

A

the maintenance of improvement of human health through prevention, diagnosis and treatment of physical or mental illness or injury

63
Q

epidemiology

A

the study of the incidence, distribution and control of disease in human populations

64
Q

infectious disease

A

disease that spread from human to human vis bacteria or viruses

65
Q

Degenerative diseases or chronic disease

A

diseases that are long-lasting and result from a gradual degeneration of the body

66
Q

5 ages of dominant causes of death

A
  1. Age of pestilence and famine: until the 19th Cdominated by infectious and parasitic diseases and regular periods of famine
  2. Age of receding pandemics: 19thC the beginning of controlling infectious disease through public health, sanitation, ect
    3.Age of degenerative disease: 20thC the emergence of degenerative disease and chronic disorders associated with aging
  3. Age of delayed degenerative disease: now: the extension of life throguh medical care and prescription medicine allowing people to live a long time
    5 A new age- the return of infectious disease: the possible return of infectious/ communicable disease such as antibiotic resistance microbes avian or swine flus ect
