Unchecked Population Growth Global Problem Presentation Emily Dixon University Scholars 203 January 24, 2001
Population Growth, Globalization, and Human Development • Rapid Population Growth => Shrinking Space => Greater Linking and Interdependence of the World’s People • Human Development depends on natural resources and the environment which are depleted by unchecked population growth • Unbalanced global integration has ties to population growth
Population Growth Statistics • Recent population growth is unprecedented in history. • It took one million years to produce the first one billion people but only ten years to add the next billion people to 1994’s world population of 5.5 billion.
Developing Countries • Most growth in developing countries; population doubled between 1960 and 1990 • Developing countries’ overall population growth expected to decrease from 2.3% per year (1960-1988) to 2.0% (1988-2000) • Exceptions: • Africa: 3.1% per year (1988-2000) • Least developed countries: 2.8% • Developing countries’ share of world population: • 77% in 1990 • projected at 80% by 2000 and 84% by 2025
Developing vs. IndustrialNations • Industrial nations’ share of world population expected to shrink from 31% in 1960 to 16% in 2025 • New births as of 1990: • 87% in third world • 13% in industrial nations • Developing countries expected 2.0% population growth from 1988 to 2000 while industrial nations expected 0.5%
Specific Problems • Environmental degradation • Poverty • Migration • from rural to urban areas • from South to North
Environmental Degradation • Rapid population growth puts the planet under intolerable strain • Adds to the enormous pressures on diminishing non-renewable resources • Causes people to move into areas prone to cyclones, earthquakes, and floods -- areas always considered dangerous and previously uninhabited • Unchecked population growth is therefore a threat to human security
Population-Environment-Poverty Nexus • In developing world, pressures on environment intensify each day as population grows • Global population estimated by the UN to be 9.5 billion by 2050, 8 billion in developing countries • population of Africa=3 times Europe and that of China=4 times North America
Population-Environment-Poverty Nexus (Continued) • To feed 9.5 billion people adequately requires 3 times the basic calories consumed today, roughly 10 billion tons of grain per year • To produce that much, have to farm all the world’s current crop land at 3 times the current global average productivity • Rapidly growing population leads to environmentally damaging adaptations: overgrazing, shortened fallow periods, and extension of cultivation into range lands and slopes
The Vicious Cycle • Environmental degradation could produce incentives to have larger families • Sub-Saharan Africa saw population growth outstrip growth in agricultural production; 2% per year(1965-80), 1.8% (1980’s) • Poorer families may have more children because they need the labor to collect ever more distant supplies of fuel or water
Poverty • Population growth usually fastest when poverty is greatest and health and education services are weakest -- in least developed countries and rural areas • Can lead to slowed economic progress and outpace some of development’s successes • Absolute number of poor rose by one fifth between 1970 and 1985, though the percent of the total population decreased • Widening gap between North and South per capita income
Migration: From Rural to Urban Areas • UN projects the world’s rural population will reach upper limit by 2015 • All future population growth beyond this point will be concentrated in urban areas • So by 2015, one half of the developing world’s people will live in urban areas • Urban areas absorb excess rural labor from natural population growth and mechanized agriculture • Rapid population growth and uncontrolled industrial development degrade urban environment, straining natural resource base and undermining sustainable and equitable development
Resulting Urbanization • Urban dwellers from 1950 to 1987 quadrupled from 285 million to one and a quarter billion • As of 1990, projected to reach 2 billion by 2000 • 8 of the world’s 10 mega-cities (13 million people or more) are in the third world • Rise of squatter settlements in developing countries • favelas in Brazil, juggias in India, barrios in Venezuela • comprise 50% of total housing stock in Caracas and Dar-es-Salaam, 40% in Karachi, and 25-30% in Tunis
Migration: From South to North • 35 million people have migrated from the South to the North in the last 30 years • One million additional people join them each year • Illegal migrants are estimated at around 15 to 30 million
Controversial Questions • What are some possible solutions? • Where does your right to have children end? • Does it end? • Does a government have the right to tell you you can only have one child? • Are you being an irresponsible global citizen if you have two? • How are reproductive rights and the environment related? • Is part of protecting the environment suppressing population? • Which is more important? • Is there necessarily a trade off?
More Questions • Should every country abide by the same reproductive mandates? • Compare the US to China • The argument for abortion is an argument for choice, the sovereignty of the individual to decide what happens to her own body. • Does the argument go the other way: women have the right to chose to have many children in the face of these population problems?
