15 Conventional Crude Oil Production has Peaked In its 2010 World Energy Outlook, the International Energy Administration projected that crude oil output would reach “an undulating plateau” of around mb/d by 2020, but it would never again regain “its all-time peak of 70 mb/d reached in 2006.”

24 Age Distribution of the World’s Population Population Structures by Age and Sex, 2005MillionsLess Developed RegionsMore Developed RegionsAge0-4MaleFemaleMaleFemaleSex and age distributions show that less developed countries have significantly younger populations than more developed countries.Almost one-third of the population in less developed countries is under age 15. In contrast, less than one-fifth of the population in more developed countries is under 15.Today there are more than 2 billion young people below age 20 in less developed regions—the age cohort that will soon become the world’s newest group of parents.Young age structures in the less developed countries are due mainly to higher levels of childbearing in recent decades.Source: United Nations, World Population Prospects: The 2004 Revision, 2005.

28 2050: the Challenges Posed by Population Growth
29 Hunger There are 950 million hungry people in the world today. The Food and Agriculture Organization says world food production will need to increase by 70 percent to keep up with population and more meat-intensive diets.Food production in the developing world will have to double just to keep up with population.
30 Severe PovertyRising food prices are pushing people into poverty. The urban poor spend percent of their budget on food.In 2010 alone, rising food prices pushed 44 million people into severe poverty.Oxfam International warns that food prices could rise by percent by 2030.
31 Urban SlumsThe size of the urban population in the developing world is growing faster than the general population.In 1990, there were an estimated 657 million people living in urban slums. Today there are 828 million.
32 Water ScarcityWater shortages have already reached crisis proportions in Western Asia and North Africa.Demand for Water is expected to outstrip supply by 40 percent within the next 20 years.
33 SanitationVery little progress has been made in improving sanitation in the developing world.Half of the population in the developing world is not using an improved form of sanitation. That’s 2.5 billion people.
34 Shortages of Arable Land Agricultural areas have expanded by only five percent since the 1970s, and the capacity for further conversion is limited.Much of the potentially arable land that remains is forest.Biofuels are competing with food producers for arable land.We are in the midst of a worldwide “land grab” by foreign interests in the developing world.
35 Loss of topsoilThe FAO estimates that by 2030, 135 million people may lose their land as result of soil degradation, including 60 million people in sub-Saharan Africa.Desertification is a major threat to China’s food production.
36 Rising Energy PricesNo one knows how energy producers will meet the world’s growing demand for energy. We will need almost 50 percent more energy by 2030.Rising energy prices are increasing the cost of producing and transporting food.
37 DeforestationThe rate of deforestation slowed in the past decade, but there are signs that rate of deforestation may be increasing again.The world’s rising demand for lumber, palm oil, and soybeans is largely responsible.
38 Rising TemperaturesThe World Meteorological Organization (WMO) reports that was the hottest decade on record.Rising temperatures will curtail crop production in many areas by percent.Rising seas will inundate many rice producing areas in South and Southeast Asia.
39 Severe WeatherUnless drastic steps are taken to reduce greenhouse gas emissions, the world will suffer some of the worst effects of climate change.Climate change experts believe that climate change will result in:Intensified DroughtsIntensified FloodingIntensified Storms
40 OceansThe annual marine fish catch peaked in 1996 at million tons and it has been declining ever since. In 2008 it was 79.5 million tons.Ninety percent of all large fish populations have disappeared.Coral reefs are endangered.
41 Loss of BiodiversityDespite the Convention on Biological Diversity, the rate of plant and animal extinction is accelerating.Scientists warns that human activity is causing the “Sixth Mass Extinction.”
42 Failing States The number of failing states is on the rise. While several factors account for the increase infailing states, virtually all failing states have high fertility rates that make it more difficult to reduce hunger and poverty.Of the 20 countries that rank highest on the 2011 Failed States Index, all but one have a total fertility rate in excess of More than half have a TFR of 5.0 or higher.

45 Changing Atttitudes and Behaviors through Mass Media Population Media Center uses radio serial dramas (soap operas) to change atttitudes and behaviors:Violence against womenChild marriageFamily planning and reproductive health
46 Delaying Age of Marriage through Economic Incentives Population Council: Berhane Hewan (“Light of Eve”) project in Amhara region of EthiopiaGirls meet regularly to acquire life-time health skills.Girls who complete the program receive a financial reward for completion (e.g. a goat).
47 8.1 Billion in 2050—How did we get there? We invested more in youth and adolescentsGirls were able to delay their age of marriageGirls were able to stay in school longerAttitudes toward girls and women improvedBoys and men treated girls and women with respect
48 8.1 billion in 2050—How did we get there? Men and women, husbands and wives, actually talked about sex and childbearingGirls and women were empoweredModern contraceptives were widely availableWomen had a range of contraceptives to choose from, andCouples had children by choice, not by chance.
49 8.1 Billion in 2050: What would it mean? Universal access to reproductive health services became a reality, not just a right.Maternal mortality fell sharply.The number of women dying of unsafe abortions declined sharply.More mothers lived long enough to see their children and their grandchildren grow up.Many obstetric fistulas were prevented, and those that were not could be treated.
50 8.1 Billion in 2050: What would it mean? The battle against HIV/AIDS and STIs was won.The level of educational attainment went up, and the rate of poverty went down.Full gender equality was achieved.Food security was enhanced. Fewer people went hungry…or starved.Water scarcity became more manageable.
51 8.1 Billion in 2050: What would it mean? The gap between energy supply and the essential energy needs of the world was narrowed.The threat of conflict was, correspondingly, diminished.Income disparities declined. The gap between North and South narrowed.Deforestation was slowed, perhaps halted.
52 8.1 Billion in 2050: What would it mean? Climate change was mitigated and prospects for adapting to climate change improved.More plants and animals survived threatened extinction.We met—or began to meet--the needs of present generations without compromising the ability of future generations to meet their own needs.
