sustainability

meeting an increased demand for resources (energy, food, fuel) in a way that protects the ability of future generations to meet their own needs

natural resources

something found in nature and is necessary or useful to humans

land use

the function of land

theories regarding the interaction of the natural environment with human societies

environmental determinism

theory that a society is formed and determined by the physical environment, especially the climate; the physical environment predisposes societies towards particular development; human society development is controlled by the environment

possibilism

theory that the environment sets certain constraints or limitations but people use their creativity to decide how to respond to the conditions of a particular natural environment

scales of analysis

spatial scale

analyzing data at a variety of scales-global, regional, national, local

global: in the world

regional: in North America

national: in Canada

local: in Quebec

region

describes an area on Earth marked by similarity in some way (a way to organize space)

regionalism

refers to a group’s perceived identification with a particular region

formal region

region marked by a shared trait (cultural, physical, etc.)

functional region

region marked by a particular set of activities that occur

perceptual/vernacular region

region that exists as an idea

regional boundaries

regional boundaries

transitional and often contested and overlapping

regional analysis

analyzing regions at a variety of scales-global, national, local

global: in the world

national: in turkey

local: in Kurdistan

population distribution

the pattern of people scattered over an area

population density

the number of people within a given area

human factors

culture, economics, history, politics

physical factors

climate, landforms, water bodies

ecumene

the habitable parts of the world

population density

measure of total population relative to land size

arithmetic population density

measure of the number of people within a given area divided by the total land area

physiologic population density

measure of the number of people per arable (farmable) land

agricultural population density

measure of the number of farmers per arable land conflicts that cause migration

carrying capacity

the number of people an area can sustain without critically straining its resources

population pyramid

provides a visual representation of a population in terms of age and sex as well as a good indication of the dependency ratio within a country and is used to assess population growth and decline and to predict markets for goods/services

rapid growth

distinguished by a wide base

stable/slow growth

characterized by a rectangular shape

declining/negative growth

describes the relationship between population and the development of a country and can be used to explain population change over time

Stage 1 pre-industrialization (no industries)

birth rates are high & death rates are high = low population growth

Stage 2 developing country (industrializing) birth rates are high & death rates begin to drop = population increases

(Afghanistan, Kenya)

Stage 3 developing country (industrializing)

birth rates begin to drop and death rates drop = population levels off

(Brazil, China)

Stage 4 developed country (post industrialization)

birth rates are low and death rates are low = population stabilizes

(U.S., U.K.)

Stage 5 developed country (post industrialization) birth rates are very low and death rates are low = population declines

(Germany, Japan, Italy)

epidemiologic transition (mortality revolution)

increase in population due to medical innovation (modern medicine) causing a decrease in the death rate

population explosion

the very great and continuing increase in human population in modern times

Thomas Malthus (1798)

argued that the size and growth of a population depends on the food supply and agricultural methods AND when there is an insufficient supply of food, people die

Ester Boserup (1965)

theorized that people will find ways to increase food production and improve agricultural methods in times of pressure

pro-natalist population policies

policies that provide incentives for women to have children, typically in countries with

declining populations
