Studied by 3 people
Demographics
study of dynamics of population change
Crude Birth Rate
(# of births/pop)*1000Crude Death Rate: (# of deaths/pop)*1000
Natural Increase Rate
rate of human growth ((CBR-CDR)/10)
Doubling Time
time it takes in years for pop to double in size
Human Development Index
a measure of well being of a country
Renewable natural capital
can be generated/replaced as fast as it is being used
Non-renewable natural capital
either irreplaceable or only replaced over geological timescales (fossils, minerals)
Natural Capital
resource that has value to humans
Capital includes:
Natural sources with value (trees, water)
Natural sources that provides services (flood protection)
Processes (water cycle)
Stage 1 of Demographic Transition Model
high stationary (high birth due to no birth control,high infant mortality rates, large families due to culturalfactors, high death rates due to famine and little medicine)
Stage 2 of Demographic Transition Model
early expanding (death rate drops, diseasereduces, lifespan increases, birth rate still high, childmortality falls)
Stage 3 of Demographic Transition Model
late expanding (birth rates fall due to contraceptives, education, empowerment, poplevels off, smaller families, low infant death rate)
Stage 4 of Demographic Transition Model
low stationary, low birth and death rates, industrialized countries, stable pop)
Stage 5 of Demographic Transition Model
declining, fertility rate low, problems of ageing workforce
Strategies for waste disposal
Landfills, Incinerators, Anaerobic Digestion, Domestic Organic Waste
Carrying Capacity
The maximum population size that an environment can sustain indefinitely given the resources available.
