Barbara Crosette, "Experts Scale Back Estimates of World Population Growth," New York Times , 20 August 2002 Demography has never been an exact science. Ever since social thinkers began trying to predict the pace of population growth a century or two ago, the people being counted have been surprising the experts and confounding projections. Today, it is happening again as stunned demographers watch birthrates plunge in ways they never expected. A few decades ago in certain countries like Brazil, Egypt, India and Mexico fertility rates were as high as five or six. As a result, United Nations demographers who once predicted the earth's population would peak at 12 billion over the next century or two are scaling back their estimates. Instead, they cautiously predict, the world's population will peak at 10 billion before 2200, when it may begin declining. Some experts are wary of too much optimism, however. At the Population Council, an independent research organization in New York, Dr. John Bongaarts has studied population declines in various countries over the last half century. He questions the assumption that when fertility declines begin they will continue to go down at the same pace, especially if good family planning services are not widely available. Sharp fertility declines in many industrialized and middle-income countries had already challenged another old belief: that culture and religion would thwart efforts to cut fertility. In Italy, a Roman Catholic country whose big families were the stuff of cinema, family size is shrinking faster than anywhere else in Europe, and the population is aging rapidly as fewer children are born. Islamic Iran has also had great success with family planning.

End of world population growth projected for 21st century November 1996 U.S. Water News Online LUXEMBURG, Austria The world's population, which has quadrupled over the past 80 years, may never double again, according to new population forecasts by the Population, Development and Environment Project at the International Institute for Applied Systems Analysis (IIASA). IIASA is a non-governmental research institution sponsored by a consortium of National Member Organizations in 17 nations. The Institute's research focuses on sustainability and the human dimensions of global change. According to IIASA's projections, there is a 66 percent chance that the world's population will not reach 11.5 billion double today's population within the next century, if ever. The projections reflect the impact of alternative assumptions for birth rates, migration, and death rates. Based on expert opinions, the projections include confidence levels for global populations and go up to the year 2100. The projections, and the assumptions on which they are based, are discussed in the new revised edition of The Future Population of the World: What Can We Assume Today?

Important note: Information in this article was accurate in 1993. The state of the art may have changed since the publication date. World Population Growth Little Affected By AIDS Reuters (09/30/93) BerlinA United Nations official has refuted a theory that transmission of AIDS will neutralize the world's population growth and eliminate the need for family planning. This prediction demonstrates a lack of knowledge about family planning and about the impact of the disease on populations, said Nafis Sadik, executive director of the U.N. Population Fund. At a conference in Berlin, Sadik informed attendees that the total number of people who die from AIDS in this decade will amount to less than two months of global population growth. About 14 million people have been infected with HIV so far, and that number is expected to rise to 40 million by the end of the century. While Sadik concedes that the virus will affect global demographics, it will not have significant influence on population growth rates.

World Food Supplies in the Context of Population Growth During the Next Twenty Years Research Fellow: Professor Tim Dyson Department of Population Studies, London School of Economics, Houghton Street, London, WC2A 2AE Tel: 0171 405 7686, Fax: 0171 242 0392 Duration: June 1993 - May 1995 ESRC award number: L320273024 Background and Aims This research aimed to: address critically the long-standing debate as to the relationship between population growth and food supplies; examine per capita food production trends during the past forty years; focus on population/food interactions in the modern world; assess qualitatively the prospects of meeting food demand, and; examine future food production possibilities in the major developed regions. Research Findings Global food demand is set to increase by at least fifty per cent in the next thirty years - mainly due to population growth. This certainly represents a major challenge. But this research does not support the idea that world population growth is currently outpacing food production. World cereal production per person has declined slightly since 1984. However, this decline has mainly been due to reductions in the area of cereal cropland, particularly in the US. The main reason has been the extremely low world price of cereals. Besides sub-Saharan Africa, Latin America is the only major developing region which has seen a negative trend in cereal production per person. Again, however, this decline in Latin America is largely explainable by reductions in cereal cropland due to low world prices. Levels of per capital cereal production in the Middle East, South Asia and the Far East regions have generally increased since the early 1980s. And it is from these regions that the bulk of the future increase in world cereal demand will come.

North America ECUADOR: Galapagos ecosystem on the edge of collapse By Kintto Lucas QUITO, Jul 8 (IPS) - Environmental mismanagement of the Galapagos Islands in Ecuador is putting several native species at risk of extinction, according to a report by the World Nature Fund and the Nature Foundation. According to the report, increasing economic pressures - caused by an annual population growth rate of six percent - could provoke a collapse of the archipelago's ecosystem. The report contends that nearly half of the island chain's reptiles and one-third of its mammals are in danger of becoming extinct. The population of the islands has reached its maximum limit, the two environmental groups argue, with population growth there three times higher than in the rest of the country. The Galapagos archipelago - which consists of 19 islands, 42 barren islets and 26 rocky outcrops - has 14,000 inhabitants, and attracts some 500 new settlers each year, the report says. The surge in population has led to an increase in the amount of land under cultivation, the extraction of construction materials and contamination due to mismanagement of solid and chemical waste, it argues.

57. Math In Daily Life -- Population Growth If birth and death rates stayed the same across the years in all parts of the world,population growth could be figured with a fairly simple formula much like http://www.learner.org/exhibits/dailymath/population.html

I n the last few centuries, the number of people living on Earth has increased many times over. By the year 2000, there will be 10 times more people on Earth than there were 300 years ago. How can population grow so fast? Think of a family tree. At the top are 2 parents, and beneath them the children they had. Listed beneath those children are the children they had, and so on and so on, down through each generation. As long as the family members continue to reproduce, the family tree continues to increase in size, getting larger with each passing generation. This same basic idea applies to the world's population. Exponential growth Population grows in the same way that money grows when it's left to compound interest in a bank. With money, growth comes through accumulating interest upon interest. The interest payments you accumulate eventually earn interest, increasing your money. With population growth, new members of the population eventually produce other new members of the population. The population increases exponentially as time passes. WORLD POPULATION Year Population A crucial difference between money and population is that money can increase without limits while population can't. Any population of living creatures is constrained by the availability of food, water, land, or other important resources. Once those resources are depleted, a population won't continue to grow exponentially. It will plateau, or even decline, as a result of disease or malnutrition. Unlike calculating interest, calculating population growth is an imprecise business.

Yet the supply of freshwater is finite and threatened by pollution. To avoid a crisis, many countries must conserve water, pollute less, manage supply and demand, and slow population growth. Caught between growing demand for freshwater on one hand and limited and increasingly polluted water supplies on the other, many developing countries face difficult choices. Populations continue to grow rapidly. Yet there is no more water on earth now than there was 2,000 years ago, when the population was less than 3% of its current size. Rising demands for water for irrigated agriculture, domestic (municipal) consumption, and industry are forcing stiff competition over the allocation of scarce water resources among both areas and types of use.
