How Can We Balance The Human Population With Our Natural

Resources?

Why is Demography Important?

Demography: Study of the size, composition, and distribution of human population.

What patterns do you see?

What is the Difference Between Developing & Developed Nations?

Developing Nations Lower Incomes (GNP) Agricultural Economy Higher population

growth What countries fall

under this category? Smaller ecological

footprint

Developed Higher Incomes Industrial Economy Lower population growth Better social support

system What countries fall

under this category? Larger ecological

footprint

Population Change in Size

Three factors affect human population size: births, deaths, and migration

Population Change = (births + immigration) – (deaths + emigration) Crude Birth Rate = # births per 1,000 people in a

population in a given year Crude Death Rate = # deaths per1,000 people in a

population in a given year

How fast is the world’s population growing?

% Population Change = (Births – Deaths)/1,000 X 100(Births – Deaths)/10The Rule of 70(DoublingTime)

70 / percent growth rate Example: In 2004 the growth rate was 1.2%. If

this rate continues the population will double in 70/1.2 = 56 years

What is the growth rate if it takes 20 years for a population to double?

Let’s determine growth rate and doubling time

What are Age Structure Diagrams?

The Number of people in young, middle and older age groups determines how fast populations grow or decline.

The number of people under the age of 15 is the major factor determining a country’s future growth.

Changes in the distribution of a country’s age groups have long- lasting economic and social impacts.

Looking Into A Crystal Ball!

Population changes in the US

After WWII fertility rate reached a peak(1946-1964) Baby Boomers!

In 2002: legal/Illegal immigration accounted for 40% of US growth

Currently close to 300 million

Projected to reach 420 million by 2050

571 million by 2100

Demographic Transition

What is Family Planning?

Provides information about prenatal care

Helps parents space births as desired

Helps parents regulate family size

Works best when reinforces customs and trends

How Can We Slow Population Growth?

Provide family planning Improve health care for infants, children and

women Develop and implement national population

policies Improve status of women Provide more education (especially to girls) Greatly reduce unsustainable patterns of

production and consumption Sharply reduce poverty!

Population Dispersion

What is Urban Sprawl?

Process of relocation of residences, shopping areas and work places from their traditional spots in cities to outlying areas (supported by the “love affair” with cars)

What are the effects of urban sprawl?

Environmental Depletion of resources (oil

consumption) Air Pollution Water Pollution Loss of Agricultural Land Loss of Habitat and

Wildlife

Health Greater risk of fatal

Accidents Higher incidents of

obesity and high blood pressure

Rise in diseases (asthma, cancer)

Noise Pollution

What are the benefits of urban sprawl?

Cities are centers for education, jobs, culture technological and economic development

More access to medical care and family planning Concentrating people in urban areas helps preserve

wildlife

How do we make urban areas more livable and sustainable?

Prevent pollution and reduce waste

Use energy efficiently Protecting biodiversity

by preserving land Promoting urban

gardens and farm markets

Promoting “green” design of buildings

The Cairo Conference

In September 1994, 15,000 leaders representing 179 nations met in Cairo, Egypt and for the first time in history reached a consensus!

All nations agreed that population is an issue of crisis proportions that must be confronted forthrightly

Plan of Action

Over the next 20 years: Empowering women Education Health

$17 billion needed each year until 2000 and additional amounts increasing to $21.7 billion by 2015

2/3 of funding would come from developing nations and the rest from developed nations

How is the plan going?

Women and girls continue to face discrimination although many countries such as India, Bangladesh and African countries are encouraging education and have outlawed female genital mutilation

HIV/AIDS epidemic has led to mortality in many countries Funding is the biggest problem:

Developing countries have provided 75% of promised amounts

Industrialized countries have provided less than half of their 1/3

Most shameful is that US Bush administration and Congress have acted to reduce their support

Two billionaires Ted Turner and Bill Gates have stepped in to fill the gap

Millenium Development Goals

Status of MDG #1

The global economic crisis has slowed progress, but the world is still on track to meet the poverty reduction target

Prior to the crisis, the depth of poverty had diminished in almost every region

MDG #2:

Hope dims for universal education by 2015, even as many poor countries make tremendous strides

Sub-Saharan Africa and Southern Asia are home to the vast majority of children out of school

Inequality thwarts progress towards universal education

MDG #3:

For girls in some regions, education remains elusive

Poverty is a major barrier to education, especially among older girls

In every developing region except the CIS, men outnumber women in paid employment

Women are largely relegated to more vulnerable forms of employment

Women are over-represented in informal employment, with its lack of benefits and security

Top-level jobs still go to men — to an overwhelming degree Women are slowly rising to political power, but mainly when

boosted by quotas and other special measures

MDG #4:

Child deaths are falling, but not quickly enough to reach the target

Revitalizing efforts against pneumonia and diarrhea, while bolstering nutrition, could save millions of children

Recent success in controlling measles may be short-lived if funding gaps are not bridged

MDG #5: Inequalities in care during pregnancy are striking Only one in three rural women in developing regions

receive the recommended care during pregnancy Progress has stalled in reducing the number of

teenage pregnancies, putting more young mothers at risk

Poverty and lack of education perpetuate high adolescent birth rates

Progress in expanding the use of contraceptives by women has slowed

Use of contraception is lowest among the poorest women and those with no education

Inadequate funding for family planning is a major failure in fulfilling commitments to improving women’s reproductive health

MDG #6: HIV/AIDS

The spread of HIV appears to have stabilized in most regions, and more people are surviving longer

Many young people still lack the knowledge to protect themselves against HIV

Empowering women through AIDS education is indeed possible, as a number of countries have shown

In sub-Saharan Africa, knowledge of HIV increases with wealth and among those living in urban areas

Disparities are found in condom use by women and men and among those from the richest and poorest households

Malaria

Production of insecticide-treated mosquito nets soars

Across Africa, expanded use of insecticide-treated bed nets is protecting communities from malaria

Poverty continues to limit use of mosquito nets Global procurement of more effective

antimalarial drugs continues to rise rapidly Children from the poorest households are

least likely to receive treatment for malaria

MDG #7:

The rate of deforestation shows signs of decreasing, but is still alarmingly high

A decisive response to climate change is urgently needed

The unparalleled success of the Montreal Protocol shows that action on climate change is within our grasp

Biodiversity

The world has missed the 2010 target for biodiversity conservation, with potentially grave consequences

Key habitats for threatened species are not being adequately protected

The number of species facing extinction is growing by the day, especially in developing countries

Overexploitation of global fisheries has stabilized, but steep challenges remain to ensure their sustainability

Water Supply

The world is on track to meet the drinking water target, though much remains to be done in some regions

Accelerated and targeted efforts are needed to bring drinking water to all rural households

Safe water supply remains a challenge in many parts of the world

With half the population of developing regions without sanitation, the 2015 target appears to be out of reach

Disparities in urban and rural sanitation coverage remain daunting

Improvements in sanitation are bypassing the poor

MDG #8:

Developing countries gain greater access to the markets of developed countries

Least developed countries benefit most from tariff reductions, especially on their agricultural products

Aid continues to rise despite the financial crisis, but Africa is short-changed

Demand grows for information and communications technology

Access to the World Wide Web is still closed to the majority of the world’s people

Debt burdens ease for developing countries and remain well below historical levels
