Seven Ways Seven Billion People Affect the Planet
›October 31, 2011 // By Geoffrey D. DabelkoSeven billion people now live on earth, only a dozen years after global population hit six billion. But the seven billion milestone is not about sheer numbers: Demographic trends will significantly impact the planet’s resources and peoples’ security.
Growing populations stress dwindling natural resource supplies while high levels of consumption in both developed countries and emerging economies drive up carbon emissions and deplete the planet’s resources. And neglected “youth bulges” could bolster extremism in fragile states like Somalia and destabilize nascent democracies like Egypt.
Here are seven ways seven billion people affect the planet, according to recent research:
Security: Nearly 90 percent of countries with very young and youthful populations had undemocratic governments at the end of the 20th century. Eighty percent of all new civil conflicts between 1970 and 2007 occurred in countries where at least 60 percent of the population is under age 30, says demographer Elizabeth Leahy Madsen. According to research by demographer Richard Cincotta, these countries may achieve democracy, but are less likely to sustain it.- Richard Cincotta: Tunisia Predicted: Demography and the Probability of Liberal Democracy in the Greater Middle East

Water: By 2025, 1.8 billion people will be living in countries with water scarcity, and fully two-thirds will be living in conditions of water stress. People are using groundwater faster than it can be naturally replenished, putting us in danger of “peak water,” says MacArthur “Genius” Fellow Peter Gleick. “We cannot talk about water without also understanding the enormously important role of population dynamics and population growth.”- Peter Gleick: Population Dynamics Key to Sustainable Water Solutions
Forests: The growing demand for energy has helped devastate tropical forests, as more than two billion people depend on wood for cooking and heating, particularly in developing countries. Projects in Indonesia, Nepal, and Uganda are fighting deforestation by providing alternative energy and incomes along with health and family planning services.- Indonesia: Health in Harmony

Future Growth: By 2050, the UN says global population could range anywhere from 8 billion to 11 billion – and where it ends up depends in large part on the status of women in developing countries. “Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged,” writes Madsen.- Elizabeth Leahy Madsen: How Did We Arrive at 7 Billion – and Where Do We Go From Here? [Part One] [Part Two]
There are no quick solutions to these seven problems. But meeting the unmet need for contraception of more than 200 million women is an effective and inexpensive way to start.

Watch: Gidon Bromberg Gives an Update on Jordan River Rehabilitation Efforts
›October 27, 2011 // By Kate Diamond
Gidon Bromberg, co-director of Friends of the Earth Middle East (FOEME), says in this short interview with ECSP that his outlook on rehabilitating the Jordan River has changed completely over the last five years. We had been “laughed at” for trying to restore the waterway, he said; now though, “we are very confident that the Jordan River south of the Galilee down to the Dead Sea will be rehabilitated.”
By building a cross-border peace park and encouraging collaboration between Israelis, Palestinians, and Jordanians on water scarcity and quality issues, FOEME aims to improve environmental and security problems that bind the three groups together.
The Jordan River has become so polluted that visitors, many of whom are devout Christians making a pilgrimage to one of the religion’s most sacred sites, have been barred from its waters due to health concerns. Furthermore, more than 98 percent of its fresh water is diverted for agricultural work, meaning that the pollutants that end up in the river are highly concentrated.
But today, Bromberg said, sewerage is being removed on both the Israeli and Jordanian sides and there is a commitment to do the same from the Palestinians. For the first time in 60 years, there are concrete plans to return fresh water to a river that is “so holy to half of humanity.”

How Did We Arrive at 7 Billion – and Where Do We Go From Here? [Part Two]
›October 26, 2011 // By Elizabeth Leahy MadsenThe world’s women will determine whether the global population in 2050 is as low as 8 billion or as high as 11 billion through their choices (or lack thereof) about the number and timing of their children. Women in developing regions of the world will have the greatest effect on these potential population trajectories. Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged.The UN estimates that the seven billionth person alive today will be born on October 31. Demographer Elizabeth Leahy Madsen explains how we got to that number, its significance, and where our demographic path might take us from here. Read part one here.
The world’s women will determine whether the global population in 2050 is as low as 8 billion or as high as 11 billion through their choices (or lack thereof) about the number and timing of their children. Women in developing regions of the world will have the greatest effect on these potential population trajectories. Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged.
The way that people decide the timing and number of their children is not easily distilled into a simple formula with a single solution. Still, some basic and important facts are known. In the developing world, where more than 80 percent of the world’s population lives, women in rural areas, those who have little or no education, and those who are poor, have larger families. As demographers have shown in modeling the determinants of fertility, women tend to seek contraception once they are confident that their children will survive to adulthood and when socioeconomic development increases the “costs” of having children, for example by motivating parents to send them to school rather than to work.
One of the most direct reasons for past declines in fertility rates was the rapid expansion of family planning and reproductive health programs, supported by country governments and international donors, that enabled women and men to more effectively choose the size of their families. But today, about 215 million women across the developing world would like to delay or avoid pregnancy but are using ineffective contraception or none at all. Funding programs to meet the family planning needs of these women, which would cost about $3.6 billion annually, would both empower them and help fertility rates continue to decline.
Beyond Access: Gender Inequality Inhibits Contraceptive Use
While increasing support for family planning programs tops the list of demographers’ recommended policies, ensuring that contraceptives are available and accessible will not alone achieve the fertility declines projected in most of the UN’s range of possibilities. Many women who are having or planning to have large families know about family planning and where to find it, but are choosing not to use contraception for cultural reasons that are often deeply engrained.
In sub-Saharan Africa, the region with the highest global fertility rate, only 16 percent of married/partnered women of reproductive age are using effective contraception. In comparison, between 62 and 75 percent of their peers in Ireland, the United States, and Uruguay – countries whose fertility rates are almost exactly at replacement level – are using it.
Logically, sub-Saharan Africa needs similar levels of contraceptive use to bring its average fertility rate towards replacement level as the UN projects, so the region’s average prevalence rate for modern contraception would need to rise by at least 10 percentage points in each of the next four decades. However, contraceptive use in the region has grown by only 0.5 percentage points or less over the past 30 years.
What is inhibiting the use of contraception? Demographic and health surveys find in Nigeria, for example, that 10 percent of married women are using an effective contraceptive method, while twice as many have an unmet need for family planning. This low use of family planning demonstrates high potential for change in the country’s demographic future, which, as the most populous in Africa, will greatly influence global and regional trends. Yet among women who do not intend to use contraception, 39 percent report that they or their family members are opposed to family planning, and another 16 percent fear side effects or have other health-related concerns. If Nigeria’s fertility rate remains unchanged, the country will be home to 500 million people by 2050.
In Pakistan, where 24 percent of births are unintended, surveys show similar barriers. Ninety-six percent of married women know about effective contraceptive methods, but only 22 percent are using one. More than one-quarter of women who do not plan to use contraceptives report that their fertility is “up to God” and 23 percent report that they or their family members are opposed to family planning. Pakistan’s population would more than double from 174 million to 379 million by 2050 if current fertility trends hold constant.
Peak Planet? Population Growth and Consumption Strain Environmental Resources
Because Nigeria, Pakistan, and other countries’ demographic trajectories may not follow the path laid out in population projections, we can’t take a world of nine billion for granted. While human ingenuity and technological advancements have improved standards of living in many countries, scientists caution that the combination of rising human numbers and growing consumption has serious environmental implications. Already, the quantity and quality of fresh water supplies are under strain, and forests in many developing countries are being rapidly depleted.
Population projections are much more than wonkish speculation – they foreshadow the serious problems that lie ahead if health, environment, and development policies aren’t strengthened. If the UN projections of our demographic future are to bear any semblance of reality, we must move beyond the status quo. While improving physical access to family planning should remain a top priority, meeting unmet need will also require addressing the deep-seated challenges of women’s education and empowerment.

Watch: Understanding Peak Water Can Help Us “Avoid the Worst Disasters,” Says Peter Gleick
›October 26, 2011 // By Kate Diamond“The advantage of the idea of peak water is that it lets us think differently about the limits that face us,” said MacArthur “Genius” Fellow and Pacific Institute President Peter Gleick in this short interview with ECSP. Gleick, who launched the latest edition of The World’s Water at the Wilson Center last week, has been talking about peak water since 2009 when he and Pacific Institute colleague Meena Palaniappan first wrote about the concept in that year’s water report (see our interview from then too).
Renewable vs. Non-Renewable
Peak water is “the idea that we are effectively running into constraints and limits on our water use,” said Gleick, in part because of population growth. “It lets us think differently about the limits to the water that’s available for us to use, and about the water that it’s appropriate for us to use, and about the policies to put in place to avoid the bad things that happen when we reach or exceed peak constraints.”
Gleick breaks the concept into three categories:- Peak renewable water: “Where we can no longer increase the amount of water we’re taking out of rivers – when we take all of it.”
- Peak nonrenewable water: “Where, very much like oil, we’re over-pumping a non-renewable ground water supply – a nonrenewable aquifer – and it becomes more and more expensive and more and more damaging and more and more difficult to pump ground water.”
- Peak ecological water: “Where the use of additional water causes more ecological harm than it provides economic benefit.”
Across all three categories, said Gleick, we are very bad at understanding limits. “We don’t measure peak water carefully, we don’t collect the data necessary to understand when we’re approaching or exceeding peak water limits.”
“But without a doubt we are exceeding peak water limits in more and more regions of the world,” he said. “And that’s going to have implications for our economies. It’s going to have implications for our environment.”
“Understanding and applying the idea of peak water is the first step toward developing strategies and institutions to avoid the worst disasters associated with overuse and inappropriate use of our water resources.” -

Water and Poverty in a World of 9 Billion, Vulnerable Agriculture in the Niger Basin
›In a two–part Water International special report on water, food, and poverty, examining 10 of the world’s major river basins, a team of researchers say that instead of worrying about having enough water to sustain the world’s growing demand, policymakers should be concerned with understanding how to manage what they already have.Introducing the special report, Simon Cook, Myles Fisher, Tassilo Tiemann, and Alain Vidal note in “Water, Food and Poverty: Global- and Basin-Scale Analysis” that the vast majority of population growth over the next few decades is expected to happen in developing countries, “where the disjunct between poverty, water and food is particularly acute.” Gaining a better understanding of water – how much we have, who uses it, and how best to use it – is essential to improving development results in the face of this demographic explosion. Water is linked with poverty and development through issues like scarcity, access, and water-related hazards (like drought, flood, and disease). But the authors conclude that water productivity – the ease or difficulty in getting water from its source to agriculture – “is by far the most important water-related constraint to improved food, income and environmental security.”In “Water, Agriculture and Poverty in the Niger River Basin,” Andrew Ogilvie et al., paint a bleak picture of life in one of West Africa’s most important basins, writing that “[m]uch of the population in the basin suffers from extreme, chronic poverty and remains vulnerable to droughts and malnutrition.” Many of the Niger basin’s 94 million residents rely on subsistence agriculture, and most of that agriculture relies on rainwater rather than groundwater irrigation systems. Over time, the authors write, “there is little doubt that climate change will increase the strain on already-vulnerable agriculture.” Population growth will exacerbate this strain; the basin’s population is expected to increase as much as fourfold by 2050. In spite of this bleak picture, the authors conclude that “[i]mprovements in rainfed agriculture can have an important impact on poverty reduction and food security due to the large population dependent on it.” -
Women and Water: Streams of Development
›“One of the things that we consistently learn is that water is a woman’s issue,” said Lisa Schechtman, WaterAid America’s head of policy and advocacy, leading off a September 23 Wilson Center on the Hill panel on gender, water, and development. Schechtman was joined in the discussion by Jae So, director of the World Bank’s Water and Sanitation Program; Christian Holmes, USAID’s Global Water Coordinator; and Geoff Dabelko, moderator and director the Wilson Center’s Environmental Change and Security Program.
Water issues affect everyone, but women often bear the brunt of water collection responsibilities, making them vulnerable to changes in access or sanitation, especially in developing countries. “Studies show that about 26 percent of a rural African woman’s time is spent collecting water,” Schechtman said. “That means that they can’t go to school, they can’t take care of their families, or go to clinics, or spend time generating income, or doing other things in their community like participating in political processes.”
What’s more, as women make the hours-long hike to get water, “they’re risking injury and sexual assault,” Schechtman added. “So there’s a really wide-ranging set of impacts, just out of the actual act of collecting water.”
The Horn of Africa: Severe Problems, Small Changes
In one town in northeastern Kenya, Holmes said women have to travel 12 miles to find water – and even then, they are drawing it from a waterhole shared with wildlife. In Ethiopia, “we have severe problems,” he said, “not the least of which is not just sanitation but also HIV and AIDS,” as HIV/AIDS patients often drink unsanitary water to take their medications. That water gives them diarrheal disease, “so they’re excreting the value of the treatment” – and women, as household caregivers, bear an ever greater burden.
In Somalia, girls drop out of school once they start menstruating because schools do not have latrines that allow them to meet their needs safely and privately. “To think that the lack of a latrine could make you drop out of school and your entire life is going to change overnight – it’s just not acceptable,” said Holmes.
In each of these cases, small changes could dramatically reduce strains on women. Holmes pointed to a USAID project in Kenya that is building wells closer to population centers and empowering women by bringing them into the decisions on developing and managing wells. In Ethiopia, NGOs are working to train women on sanitation and hygiene, which could reduce the burden of illness on women and their families. And in Somalia, the simple addition of women’s latrines at schools would mean girls can continue their education beyond puberty.
Closing the Water Gender Gap
The World Bank’s 2012 World Development Report on Gender Equality and Development recommends that development professionals “look at the gender gaps in basic endowments, like access to health, access to water resources, access to land,” and determine not just how they affect men and women differently but why those gaps exist in the first place, said Jae So.
A CARE and Swiss Development Corporation study of water services in Nicaragua found that when men realized how much of a role water-related activities played in women’s day-to-day lives, “it energized the entire community to really devote their collective resources” towards improving water management, said So.
“Water touches everything else in one’s life,” said Holmes. “You can link it to water and climate change, water and health, water and food, water and conflict, water and education – all are interwoven.”

Watch: First Impressions From the Inaugural SXSW Eco Conference
›October 6, 2011 // By Schuyler NullOur director, Geoff Dabelko, provides a brief update from South by Southwest’s (SXSW) first Eco conference, being held in Austin, Texas this week:
Bill Ritter, former governor of Colorado, was impressive in an interview with Bryan Walsh of Time magazine, seamlessly alternating between technical and policy questions about energy security.
Ned Breslin, CEO of Water for People, provided some real talk, challenging the notion that it’s “easy” to provide needy populations with freshwater. It’s not as simple as “$25 saves a life,” he said. Providing long-term, sustainable water and sanitation solutions to people around the world requires a great deal of hard work, particularly on financing and ownership questions.
Finally, Jon Foley of the University of Minnesota’s Institute on the Environment presented a five-step response to what he called today’s three main food challenges: providing enough to feed today’s population, tomorrow’s (an estimated nine billion people by 2050), and doing it all in a sustainable fashion. The Institute on the Environment publishes an almost-quarterly magazine, Momentum, whose work we’ve featured before on New Security Beat (here, here, and here), and, incredibly, is available, delivered to your house, for FREE. Highly recommended.
Stay tuned for more updates from SXSW, including the ECSP-supported panel, “Three Great Ideas That Won’t Be On the Rio+20 Agenda.”
