Peter Gleick: Population Dynamics Key to Sustainable Water Solutions
›October 21, 2011 // By Theresa Polk“Water is tied to everything we care about,” said MacArthur “Genius” Fellow and President of the Pacific Institute Peter Gleick in an interview with ECSP. However, “we cannot talk about water or any other resource issue…without also understanding the enormously important role of population dynamics and population growth.”

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 Null
Our 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.” -
Weathering Change: New Film Links Climate Adaptation and Family Planning
›“Our planet is changing. Our population is growing. Each one of us is impacting the environment…but not equally. Each one of us will be affected…but not equally,” asserts the new documentary, Weathering Change, launched at the Wilson Center on September 22. The film, produced by Population Action International (PAI), explores the devastating impacts of climate change on the lives of women in developing countries through personal stories from Ethiopia, Nepal, and Peru. Family planning, argue the filmmakers, is part of the solution.

Aaron Wolf on Water Management, Agriculture, and Population Growth in the Middle East
›
In terms of groundwater depletion, “Yemen and Gaza are probably the two places worst off in the Middle East,” Aaron Wolf told ECSP in a recent interview. Wolf, a water expert and geography professor at Oregon State University, said population growth across the broader Middle East region has led to intensified groundwater pumping in recent years. This trend has raised the prospects for water-related conflict down the road, as countries drain their groundwater stocks faster than the aquifers can recharge. Potentially complicating matters further, said Wolf, is that most aquifers in the Middle East cross international boundaries.
Despite the region’s history of water tensions, Wolf said the unprecedented level of demographic change currently being experienced across the Middle East is not necessarily a recipe for future confrontations over the resource, in part thanks to the existence of water-sharing agreements in the area. Nevertheless, mounting demand will likely force water-users across the region – especially within the agriculture sector – to change the ways they utilize the resource.
Accounting for 80 to 90 percent of total water usage in some Middle Eastern countries, agricultural operations have already been forced to adjust to the evolving water-access situation. While moving from flood irrigation to drip irrigation represents one policy option if sufficient funds are available, Wolf said doing away with local food production “is a path that a lot of countries are going to have to take” to ensure a relatively stable water supply for their populations’ drinking, cooking, and cleaning needs.
Wolf added that one frequently discussed but not entirely realistic option for addressing the region’s water-supply concerns involves desalination. To date, widespread deployment of the technology has been hampered by high costs and substantial energy requirements, although that hasn’t stopped a few countries in the region – among them the United Arab Emirates, Saudi Arabia, and Israel – from becoming partially reliant on converted fresh water.
Wolf maintained that desalination’s hefty price tag means the technology is useful only for urban population centers near the coast. Moving converted sea water further inland remains a non-starter, he said, because transporting it requires an enormous amount of energy (a cubic meter of water weighs a metric ton).
For the same reasons, Wolf asserted, using desalinated water for agriculture doesn’t seem to be in the cards any time soon. “Right now a cubic meter of desalinated water costs about 40 cents, and you can’t use that for agriculture unless it drops down to about 8 cents a cubic meter,” Wolf said. “So until you can irrigate with desalinated water, it really doesn’t go a long way towards mitigating the larger water crisis.”

Digging Deeper: Water, Women, and Conflict
›
It’s not just “carrying water from a water point, but it’s discharging responsibilities that a woman has for using and managing water which may make her vulnerable to violence and bring her into risky areas,” said Dennis Warner, senior technical advisor for water and sanitation at Catholic Relief Services (CRS), at the Wilson Center on August 29.

Carl Haub, Yale Environment 360
What If Experts Are Wrong On World Population Growth?
›September 22, 2011 // By Wilson Center StaffThe original version of this article, by Carl Haub, appeared on Yale Environment 360.
In a mere half-century, the number of people on the planet has soared from 3 billion to 7 billion, placing us squarely in the midst of the most rapid expansion of world population in our 50,000-year history – and placing ever-growing pressure on the Earth and its resources.
But that is the past. What of the future? Leading demographers, including those at the United Nations and the U.S. Census Bureau, are projecting that world population will peak at 9.5 billion to 10 billion later this century and then gradually decline as poorer countries develop. But what if those projections are too optimistic? What if population continues to soar, as it has in recent decades, and the world becomes home to 12 billion or even 16 billion people by 2100, as a high-end UN estimate has projected? Such an outcome would clearly have enormous social and environmental implications, including placing enormous stress on the world’s food and water resources, spurring further loss of wild lands and biodiversity, and hastening the degradation of the natural systems that support life on Earth.
It is customary in the popular media and in many journal articles to cite a projected population figure as if it were a given, a figure so certain that it could virtually be used for long-range planning purposes. But we must carefully examine the assumptions behind such projections. And forecasts that population is going to level off or decline this century have been based on the assumption that the developing world will necessarily follow the path of the industrialized world. That is far from a sure bet.
