Desertification • Over-grazing • Water-withdrawal • Drought • Food security
Demographic Transition Theory Demographic Transition: A Model of economic and cultural change to explain declining death rates, declining birth rates, and rising life expectancies in Western nations as they became industrialized. Proposed by Frank Notestein in the 1940s–1950s
Stage 1: Pre-industrial • High birth rates • No family planning • Children need for agricultural labor • Children provide family security • Lower rates of child survivorship • High death rates • Disease and famine • Lack of medical knowledge • Poor hygiene and sanitation • No population growth No countries are currently in this stage.
Stage 2: Transitional • Birth rates remain high • Death rates fall • Decline in infant mortality • Improved medical knowledge • Improved sanitation • Food security • Increased connectivity • Agriculture remains dominant economic activity • Population growth begins and increases rapidly Examples: Afghanistan, Yemen, much of Central and West Africa
Stage 3: Industrial • Birth rates fall • Empowerment of women • Lower infant mortality = less pressure to have children • Less need for agricultural labor • Improved education • Death rate reaches stability • Urbanization and industrialization • Population growth slows down Examples: Mexico, Indonesia, portions of North and Southern Africa
Stage 4: Post-Industrial • Low birth and death rates • Populations are high but growth is slow/stable • Largely urban population • Industrial / service economies Examples: United States, Canada, Australia, Northern Europe
A 5th Stage? (Decline) • Characterized by negative natural increase • Very low birth rates • Economic success • Education • Decline in religious adherence • Aging population • Long-term low birth rates • Population age-structure leads to slightly higher death rates Examples: Germany, Russia, much of Eastern Europe
Demographic Transition Theory • Length of stages varies from country-to-country • Size of population change (growth) depends on the length of time spent in stages 2 and 3. • The lag between the initial fall in death rates and the subsequent fall in birth rates.
Sub-Saharan Africa: Population • Population of roughly 836 million • 2.5% yearly growth (World: 1.2%) • Doubling time of 25 years • 1.15 billion by 2025 • High fertility rate: 5.3% (World: 2.6%) • Still primarily rural: 35% (World: 50%) • Urbanizing rapidly
Population Characteristics • Differences between Southern Africa and the rest of Sub-Saharan Africa • Impact of HIV/AIDS • Stage of development / demographic transition
Sub-Saharan African Diaspora • Out of Africa • To Europe • Brain drain • Within Africa • Search for work • Circular migrations • Refugees • 4.5 million • 1/3 of world total
