Demography, Climate in the Spotlight at Planet Under Pressure
›March 27, 2012 // By Kayly OberLondon’s 2012 Planet Under Pressure conference, on all things global change – including climate, population, global risks, and food security – kicked off with a bang on March 26 and ECSP was there to cover it. We’ll be here throughout the week following all of the most pertinent population, health, and security events – we invite you to visit our booth if you happen to be in London, join the conversation on Twitter (#Planet2012), and/or watch the livestream.
During the opening plenaries, UK Scientific Advisor and all-around environmental all-star Sir John Beddington was the first to introduce population into the discussion.
Speaking on “The Planet in 2050” panel, Beddington immediately noted that really 2050 is too far out and instead we should focus on the next two decades. Within these 20 years the trajectory of greenhouse gas emissions and climate change will be determined by the extent and manner of urbanization and demographic changes, particularly in Africa.
“How are we going to generate an infrastructure to feed 500 million Africans in the next 13 years?” Beddington asked.
Beddington’s talk could be considered a rejoinder to his famous “perfect storm” analogy, outlined in The Guardian in 2009:Our food reserves are at a 50-year low, but by 2030 we need to be producing 50 percent more food. At the same time, we will need 50 percent more energy, and 30 percent more freshwater.
In a later session, “Securing Global Biodiversity,” Simon Stuart, chair of the species survival commission of the International Union for Conservation of Nature (IUCN), expanded on this “perfect storm” analogy.
There are dramatic problems out there, particularly with water and food, but energy also, and they are all intimately connected. You can’t think about dealing with one without considering the others. We must deal with all of these together.
He agreed that the global challenge of our day hinged on how human needs add pressures to the natural environment. Rising demand for energy, food, and freshwater not only influences climate change but also exerts unprecedented pressure on soil quality and biodiversity.
But although we’re impeded by major challenges, including “unsustainable economic models,” a lack of public support, and a massive need for investment in conservation, we have made some strides, Stuart said. The Convention on Biological Diversity’s strategic plan for biodiversity, established in 2010, sets 20 targets for biodiversity conservation by 2020. Stuart believes this is the beginning of acknowledging the urgency of addressing the threat to biodiversity.
Tim Coulson, professor of population biology at Imperial College London, compared the efficiency of either reducing fertility rates or per capita consumption to determine the best way to reduce humanity’s impact on the planet.
Coulson ran two simple simulations using India and the United States as case studies. In one model, he changed fertility rates by one percent per year for 50 years. In the other, he decreased per capita consumption by one percent per year for 50 years. What he found in both cases was that decreasing per capita consumption achieved the most rapid change in human impact on the environment. Nevertheless, he acknowledged that a longer-term course of action of declining fertility rates was needed to keep impact stable.
Readers beware, however – this type of experiment is an incredibly simplified exercise in the intersection of people and the environment. A more varied set of scenarios would produce more useful results. As Beddington mentioned, populations in sub-Saharan Africa have both the highest growth rates and the most direct impact on the environment due to their higher reliance on natural resources for livelihoods.
And, perhaps most importantly, as one commentator noted, these scenarios do not take into account cost factors. For instance, in order to reduce greenhouse gas emissions through more energy efficient buildings and transport, the United States would need to invest $1.1 trillion through 2030. Alternatively, the cost to provide for the 215 million women in developing countries who want to avoid pregnancy but are not using an effective means of contraception is estimated at $3.6 billion. Using the “wedge” climate model, meeting unmet family planning needs would be equivalent to the amount of greenhouse gas emissions saved by converting entirely to electric vehicles – at a fraction (about five percent) of the cost.
Stay tuned for more updates from ECSP at the Planet Under Pressure Conference. We’ll also be posting pictures from the conference to our Facebook and Flickr pages.

Fourth World Water Development Report Released by UN
›The beginning of last week’s World Water Forum in Marseille also marked the release of UNESCO’s fourth edition of the World Water Development Report. Chief amongst the challenges outlined in the new report are meeting demand from growing population and consumption. Agriculture accounts for 70 percent of water usage, according to the report, and globally we will require 70 percent more food over the next 40 years, introducing the possibility of overtaxing already-stressed water resources – all while adapting to climate change. There are substantial gains to be had in increasing farm-to-table efficiency, especially in developing countries, the authors sagely point out, but the supply challenge remains a huge one.
This year’s edition also adds several new sections, including on women and water. “The crisis of scarcity, deteriorating water quality, the linkages between water and food security, and the need for improved governance are the most significant in the context of gender differences in access to and control over water resources,” write the authors. “These challenges are expected to become more intense in the future.”
The integrated nature of today’s water issues is a highlight throughout the report. “Accelerated change” will create new threats and “interconnected forces” create uncertainty and risk, but UNESCO emphasizes that if policymakers are made aware of these issues, ultimately “these forces can be managed effectively and can even generate vital opportunities and benefits through innovative approaches to allocation, use, and management of water.”

PBS ‘NewsHour’ and Pulitzer Center Examine Water Shortage and Health Issues in Ghana and Nigeria
›The PBS NewsHour continued its collaboration with the Pulitzer Center on Crisis Reporting on international reporting last week with an episode on water infrastructure in Ghana and Nigeria. The coverage is especially apropos on World Water Day.
Correspondent Steve Sapienza spoke to reporters in Ghana and Nigeria to highlight long-running access and sanitation issues in both countries caused by poor infrastructure that has not kept up with growth.
Ameto Akpe is a local reporter for Nigeria’s BusinessDay, where her stories “target the contradiction of a country with immense oil wealth and great water resources that are not reaching their citizens.” In the city of Makurdi, capital of the north-central Benue State, she reports on the hundreds of thousands of people who rely on either high-priced water delivery or untreated water drawn straight from the Benue River.
“The previous attempt to build a water treatment plant ended in scandal in 2008,” says Sapienza, “with an unfinished treatment facility and city officials unable to account for $6 million.”
“Unfortunately, the waterworks is only half of the solution to Makurdi’s water problem,” writes Akpe on the Pulitzer Center. “The other half is a system of pipes to deliver the water to the people – and that project is just a twinkle in the eye of a handful of contractors and bureaucrats.”
In Ghana, metro TV reporter Samuel Agyemang explains similar access and sanitation issues in the capitol of Accra and its suburb of Teshie, where some residents have waited decades for piped water, despite substantial foreign investments.
The Pulitzer Center’s Peter Sawyer explains in a companion piece that “the population of Accra has grown enormously in the past several decades. But the water supply system has not grown with it.” As a result, the Ghana Water Company is constantly playing catch-up to provide water to communities, many of whom do not understand how to demand accountability from their officials, says Agyemang.
According to UN estimates, Ghana’s population has increased by more than 10 million people since 1990. Nigeria is one of the fastest growing countries in the world, with 158 million people currently and the UN medium projection estimating a possible 389 million by mid-century.
Reporter Ameto Akpe will be speaking about Nigeria’s water and sanitation problems at an upcoming all-day event on Nigeria at the Wilson Center, scheduled for April 25.

Lakis Polycarpou, State of the Planet
Finding the Link Between Water Stress and Food Prices
›March 19, 2012 // By Wilson Center StaffThe original version of this article, by Lakis Polycarpou, appeared on State of the Planet.
Over the past decade, average global food prices have more than doubled, with 2008 and 2010 seeing excruciating price spikes that each had far-reaching economic, geopolitical, and social consequences.
What explains this long-term trend – and why did prices spike so much higher in the years that they did?
For policymakers at all levels, answering that question is of vital importance if there is to be any hope of feeding the world’s growing population in the coming decades, much less maintaining social order.
According to recent research by the New England Complex Systems Institute, spikes in food prices are so closely correlated with social unrest that they were able to identify a particular food-price threshold above which food riots are very likely.
The most obvious cause for high food prices is oil – in fact, charts showing the correspondence between food and oil prices show an eerie overlap, especially in the last half decade. Water scarcity and climate are major players as well, however. According to the just released United Nations World Water Development Report, demand for water will grow by 55 percent in the next 40 years, and farmers will need 19 percent more water by 2050 just to keep up with growing food demands.

Central Asia’s Dam Debacle
›March 13, 2012 // By Wilson Center StaffThe original version of this article, by Eelke Kraak, appeared on ChinaDialogue.
The Toktogul Dam in Kyrgyzstan is an imposing structure. The dam guards the largest and only multi-annual water reservoir in central Asia. The cascade of five hydroelectric stations downstream produces 90 percent of Kyrgyzstan’s power. Cotton fields thousands of kilometers away in Kazakhstan and Uzbekistan depend on the release of water from this dam.
The Toktogul is literally and figuratively the “valve” of the Syr Darya River. But by relying on large-scale engineering projects to control the river, these countries have ignored the fundamentally political nature of water management.
The significance of the Toktogul dam goes beyond its economic benefits. It was the center piece of the Soviet Union’s efforts to conquer nature in its drive to modernize central Asia. When it became fully operational in the late 1980s, the project to control the region’s rivers seemed complete.
But the costs have been high. The Aral Sea, the terminal lake of the main sources of water in central Asia, the Syr Darya and Amu Darya rivers, has shrunk to almost nothing. Many areas surrounding what is left of the lake are heavily polluted. Moreover, the now independent Syr Darya riparian countries – Kyrgyzstan, Uzbekistan, Tajikistan and Kazakhstan – disagree on how the Toktogul should be operated.

Reaching Out to Environmentalists About Population Growth and Family Planning
›“Promoting women’s empowerment is an effective strategy for looking at climate and the environment but also is important in its own right,” said the Sierra Club’s Kim Lovell at the Wilson Center on February 22. “Increasing access to family planning for women around the world is a climate adaptation and climate mitigation solution.” [Video Below]Drawing on research by Brian O’Neill (National Center for Atmospheric Research) and others Lovell explained that meeting the unmet need for family planning around the world could provide up to 16 to 29 percent of the emissions reductions required by 2050 in order to avoid more than two degrees of warming (the target set by nations to prevent the most damaging effects of climate change).
For environmentalists and those concerned with climate change, “sometimes the idea has been that population is toxic, that we can’t talk about population growth,” said Nancy Belden of Belden Russonello and Stewart Consulting, but the results of a recent survey and several focus groups conducted in association with Americans for UNFPA demonstrate that there is great potential for engaging the environmental community in such a discussion.
Belden and Lovell were joined by Kate Sheppard from Mother Jones to discuss how the population and environment communities can come together in the lead-up to the Rio+20 UN sustainable development conference.
Besides providing a basic health commodity, empowering women through access to family planning also improves adaptation outcomes, said Lovell. “Climate change is already happening and women and families around the world are suffering from the effects of water scarcity [and] of erratic weather patterns,” she said. But “when women have the ability to plan their family size and have more choices about their families and about their reproductive health and rights, that makes it easier to adapt to those climate change effects that are already taking place.”
Resonating With Environmental Priorities
“The people who really care about the environment are generally the same people who care about access to contraception and birth control and family planning…they’re a ready audience to hear about these connections and they’re a ready audience to take action about them,” said Kate Sheppard. Reproductive rights issues are something that people can really connect with, she said; “most women, most men too…understand why it’s an important issue and they’ve understood it in their own life and they have [a] very strong response to it.”
When we approach the linkages between environment and population, said Sheppard, it is important to recognize the role of empowering language – language about access to services, education, and resources for women.
The aim of the Americans for UNFPA survey was to find out whether environmentalists can be engaged in discussions of population issues such as family planning and international voluntary contraception, and if so, how?
The results show that “environmentalists are ready to talk about population, they’re ready to listen – it’s not toxic,” said Belden. She outlined three key findings:
First, environmentalists prioritize the environment but they also give a high priority to empowering women, said Belden. “Population pressures are seen as an environmental problem…they don’t dismiss it,” yet the “strongest framework that we could come up with…for engaging people on the issues around voluntary family planning and contraception focuses on women.”
Second, the environmental community is relatively optimistic about the potential outcomes of family planning programs and of foreign aid in general. When queried, half of the environmentalists strongly supported the idea of U.S. contributions to UN programs that provide voluntary access to contraception in developing countries, said Belden.
When asked to mark their top priority among a list of possible outcomes of providing voluntary access to contraception, 47 percent of the environmentalists selected either “improving living conditions for women and their families” or “ensuring women have options and can make reproductive decisions” as their top priority. While a significant number are also concerned about stalling population growth, this integrative focus on improving the lives of women and their families is heartening, said Belden.
In the Run-Up to Rio+20, More Than Pop
One point that all three speakers stressed is the need to integrate consumption into the integrated population message. In her survey work, Belden found that “if you don’t talk about consumption in the same breath, [environmentalists] start wanting to put it in there because otherwise…this is someone blaming others.”
Lovell similarly highlighted that “if we’re working to ensure a sustainable planet for future generations to come, we have to think about consumption and population.” For instance, “the United States makes up five percent of the world’s population but consumes 25 percent of the world’s resources,” she said.
Said Sheppard: “It’s not simply a problem that the numbers of people here on the Earth are going up, it’s a problem of how people, especially here in the U.S., live.”
It is imperative – especially from a sustainable development standpoint – that while working towards integrating environment and population we remain focused on a message that includes “using less but still having a high quality of life” here at home, said Sheppard.
