Watch: Peter Gleick on Peak Water
›February 5, 2009 // By Wilson Center Staff“The concept of ‘peak water’ is very analogous to peak oil…we’re using fossil groundwater. That is, we’re pumping groundwater faster than nature naturally recharges it,” says Peter Gleick in this short expert analysis from the Environmental Change and Security Program. Gleick, president and co-founder of the Pacific Institute and author of the newest edition of The World’s Water, explains the new concept of peak water.

Human Health Dependent on Biodiversity, Argue Scientists
›January 29, 2009 // By Rachel Weisshaar
“There’s such a fundamental misunderstanding that most people have about the environment—that it exists outside of us,” said Harvard Medical School’s Eric Chivian at the January 14, 2009, launch of Sustaining Life: How Human Health Depends on Biodiversity, which he co-edited. This disconnect “is really at the heart of the global environmental crisis, and it’s the reason we wrote this book.” Chivian was joined by the Natural Capital Project’s Michael Wright and the Heinz Center’s Thomas Lovejoy, who called Sustaining Life “a remarkable achievement,” for a discussion of the myriad ways in which biodiversity benefits human health—and how its loss endangers us.
Proof Positive: Biodiversity Supports Health
The most exotic—and unlikely—species can yield valuable discoveries, Lovejoy explained. For example, slime molds on the banks of the Zambezi River repel their enemies with chemicals that can treat cancers resistant to Taxol, one of the main chemotherapy drugs—which is itself derived from the needles and bark of the Pacific yew tree. Chivian offered another remarkable example: The best new pain medication, which is 1,000 times more powerful than morphine, is derived from the toxins of marine cone snails.
Of Polar Bears and Parasites
Polar bears—which new research suggests are likely to be extinct in the wild by 2100 due to the melting of the Arctic ice sheet—may help cure several devastating diseases. Polar bears “den,” or near-hibernate, for five to nine months of each year, yet substances in their blood prevent them from losing bone mass during that time. “Osteoporosis is an enormous public health problem; it kills some 70,000 people in the United States every year, costs the U.S. economy $18 billion dollars a year,” explained Chivian.
When they den, polar bears go for months without eating, drinking, defecating, or urinating. Studying this phenomenon may provide humans with alternatives to dialysis or kidney transplants. Finally, while polar bears are extremely obese, they do not develop Type II diabetes. In contrast, 16 million Americans—6 percent of the population—have obesity-related Type II diabetes, costing the United States $91 billion a year. “Again, polar bears may hold the secret for treating this very difficult and lethal disease,” said Chivian.
Not only can certain species help us treat human diseases, but the loss of biodiversity can increase the prevalence of others. For instance, Lyme disease is more common in degraded environments with low vertebrate diversity. In these environments, the disease spreads more quickly because the white-footed mouse—the best vector for Lyme disease—has fewer predators and competitors for food.
Better Safe Than Sorry
By providing dozens of concrete examples of how we depend on and benefit from the environment, Sustaining Life is “a wonderful rebuttal to people who call conservationists treehuggers,” said Wright. Yet he reminded the audience that the path from species to valuable product is serendipitous and unpredictable. Therefore, he argued, we should endeavor to protect all species in order to save those that may most benefit human health.
Chivian, who shared a Nobel Peace Prize for his work on the medical dimensions of nuclear war, argued that it is difficult for the public to grasp the threats posed by climate change: “The level of complexity and abstraction is really an order of magnitude—or many times more than that—greater than it is about nuclear weapons…and therefore, it’s even more essential for physicians and public health professionals to describe and discuss these global environmental changes in human-health terms.”

Food Production Goes Global, Sparking Land Grabs in Developing World
›December 8, 2008 // By Will Rogers As global food prices soar and population growth and urbanization shrink the supply of arable land, many countries have been forced to adopt new forms of production to secure their food supply. But instead of embracing sustainable land-use practices and improving rural development, some nations have shifted food production overseas, igniting a massive land grab in the developing world.
From the Persian Gulf to East Asia, governments and international companies alike have been lobbying developing countries in Africa and Asia to produce grain for food and alternative energy. The Guardian reported on November 22nd that Qatar recently leased 40,000 hectares of Kenyan farmland in return for funding a £2.4 billion port on the island of Lamu, a popular tourist site just off the Kenyan coast. The Saudi Binladen Group is said to be finalizing a deal with Indonesia to lease land for basmati rice production, while other Arab investors, including the Abu Dhabi Fund for Development, have bought land rights for agricultural production in Sudan and Pakistan. Ethiopian Prime Minister Meles Zenawi has been “courting would-be Saudi investors,” despite his country’s own deplorable food insecurity and chronic malnutrition.
Meanwhile, the Telegraph reported that South Korea’s Daewoo Logistics has been working to secure a 99-year lease for 3.2 million hectares of farmland in Madagascar that it will use to “grow 5 million metric tons of maize a year and 500,000 tons of palm oil” to use as biofuel in South Korea. The company says it expects to pay almost nothing besides infrastructure costs and employment training in return for its use of the land. Despite Madagascar’s rapid population growth and pervasive food insecurity, the deal, if signed, will allow the South Korean company to lease approximately half of the current arable farmland on the island state.
In an effort to combat a freshwater shortage, China has secured an agreement with Laos for a 50-year lease of 1,600 hectares of land in return for funding a new sports complex in Vientiane for the 2009 Southeast Asian Games. And with only 8 percent of the world’s arable land and more than one-fifth of the world’s population to feed, China continues to encourage its businesses to go outside China to produce food, looking to developing countries in Africa and Latin America.
Jacques Diouf, director-general of the UN Food and Agricultural Organization, recently warned that these deals are a “political hot potato” that could prove devastating to the developing world’s own food supply, as several of these states already face severe food insecurity. Diouf has expressed concern that these deals could breed a “neo-colonial” agricultural system that would have the world’s poorest and most malnourished feeding the rich at their own expense.
And with land rights a contentious issue throughout the developing world—including in Haiti, Kenya, and Sudan, for instance—these agreements could spark civil conflict if governments and foreign investors fail to strike equitable deals that also benefit local populations. “Land is an extremely sensitive thing,” warns Steve Wiggins, a rural development expert at the Overseas Development Institute. “This could go horribly wrong if you don’t learn the lessons of history” and attempt to minimize inequality.
As food prices continue to climb, more and more countries are likely to scramble to gain access to the developing world’s arable land. Without land-use agreements that ensure a host country’s domestic food supply is secure before its foreign investor’s, long-term sustainable development could be set back decades, something impoverished developing countries simply cannot afford.

Coltan, Cell Phones, and Conflict: The War Economy of the DRC
›December 2, 2008 // By Will RogersEclipsed by the world economic downturn, the great heist of the Democratic Republic of the Congo’s (DRC) resources continues unabated. In recent weeks, former Congolese General Laurent Nkunda’s Tutsi rebels have launched offensives in North Kivu, and the Congolese army and UN peacekeepers have been hard-pressed to stop them.
With some of the world’s greatest reserves of minerals, metals, natural gas, and oil—including 10 percent of global copper reserves and 33 percent of global cobalt reserves, in addition to vast deposits of diamonds, gold, silver, timber, uranium, and zinc—eastern DRC has frequently been exploited by rebel groups, foreign militaries, and international firms looking to fill their coffers. Other African conflicts have been sustained by diamonds and gold, but in the eastern DRC, columbo-tantalite (coltan), is one of the most coveted commodities. And with 80 percent of global reserves of coltan lying in the DRC, coltan has become the new “black gold”.
Coltan is refined into tantalum powder to make heat-resistant capacitors in cell phones, laptops, and other high-end electronics. With global technological innovation on the rise, the demand for the mineral continues to surge, creating the incentive for miners and traders to step up their efforts to extract it. At its peak in September 2001, coltan traded at close to $400 per kilo; today, the market price has steadied at around $100 per kilo.
Struggle for control over coltan mines remains central to the conflict in eastern DRC, which has claimed more than four million lives over the past decade. Whether it is a Hutu militia like the Democratic Forces for the Liberation of Rwanda (FDLR), which fled Rwanda< following the 1994 genocide; a Congolese rebel faction, like Nkunda’s Tutsi rebels; or the Congolese army itself, each has a stake in the lucrative coltan trade.
These groups, including the Congolese army, have been active in extorting coltan miners, as demonstrated by footage from “Blood Coltan.” With coltan miners earning $10 to $50 a week, five times more than most other Congolese earn in a month, government and rebel troops have taxed the miners for access to the mines—making control of the mines and surrounding land violently competitive. Despite the dangerous conditions of the mines, which have led to countless deaths, workers remain plentiful. And as demand for coltan has increased in recent years, the number of child laborers in the mines has grown, with approximately 30 percent of schoolchildren in the region deferring their education for mining work.
In addition to the human toll, coltan exploitation has also proven severely destructive to the region’s environment and biodiversity. North and South Kivu provinces contain the DRC’s greatest concentrations of coltan, and Kahuzi Biega National Park (KBNP), one of the last sanctuaries for the critically endangered eastern lowland gorilla, spans both provinces. Coltan mining has destroyed much of the gorillas’ natural habitat, leaving them vulnerable to poachers who kill them and sell them to coltan miners and rebel groups for food. According to park surveys, the population of eastern lowland gorillas in KBNP plummeted from 8,000 in 1991 to approximately 40 in 2005.
DRC Ambassador to the United States Faida Mitifu, speaking recently at a U.S. Institute of Peace event, urged the U.S. Congress to adopt what she describes as a Kimberly Process for coltan in an effort to end the illegal export of coltan from eastern DRC. A “Goma Process” could certify the origin of coltan and place punitive levies on those involved in the trade of conflict coltan from eastern DRC—much as the Kimberly Process does for diamonds. Meanwhile, building infrastructure and creating a regulated sustainable resource extraction industry could also help the country generate much needed revenue and profitable trade regimes. But given that coltan is smuggled into Rwanda and other bordering countries and traded to non-U.S. markets, the support of the international community and the UN Security Council would be critical to the success of this initiative and creating a lasting peace in the region. The UN Security Council has already condemned coltan’s role in financing conflict, so the creation of a Goma Process could be a logical—and achievable—next step.

›The National Intelligence Council has released Global Trends 2025: A Transformed World, an unclassified report seeking to identify a range of future security trends. As the Washington Post notes, the report “makes for sometimes grim reading in imagining a world of weak states bristling with weapons of mass destruction and unable to cope with burgeoning populations without adequate water and food.” ECSP hosted a review of an intermediate draft of the report in July 2008.
The United Nations, the U.S. Department of Defense, and several other militaries are spearheading an effort to fight climate change and ozone-depleting substances. The partnership comes out of a conference held in Paris earlier this month on the role of militaries in protecting the climate. Andrew Alder, who attended the conference, writes, “the Pentagon can also play a leading role in reducing carbon emissions, ironically helping to reduce the very threat for which it is preparing.”
In “Quantum of Solace,” James Bond goes up against a villain who takes control of a country’s water supply.

PODCAST – Jean-Yves Pirot on PHE Integration and Environmental Management
›November 17, 2008 // By Wilson Center Staff“Time is pressing, and we need all hands on deck,” says Jean-Yves Pirot, an ecologist with the International Union for Conservation of Nature (IUCN), on the urgent need for conservationists to look outside their sector for help in improving sustainable environmental management in developing countries. In a podcast with ECSP’s Gib Clarke, Pirot, who coordinated the “Healthy People, Healthy Environment” stream at the recent World Conservation Congress, discusses the challenges of integrating population and health into environment programs. He urges conservationists to forge synergies with health and development specialists in order to scale-up small, short-term projects and provide long-term health and environmental benefits to the poor. -
Fertile Fringes: Population Growth Near Protected Areas
›November 7, 2008 // By Rachel Weisshaar“Protected areas are the backbone of biodiversity conservation strategies,” so it is critical to examine how population growth is affecting them, said Justin Brashares of the University of California, Berkeley, at “Fertile Fringes: Population Growth at Protected-Area Edges,” an October 22, 2008, meeting sponsored by the Environmental Change and Security Program (ECSP). “Biodiversity conservation objectives are being impacted by higher deforestation rates, [natural resource] offtake rates, [and] increasing pressure on the protected area” due to high local population growth, explained George Wittemyer of Colorado State University. Brashares and Wittemyer, who recently co-authored an article on population and protected areas in Science, were joined by Jason Bremner of the Population Reference Bureau.
To Stay or To Go?
“Many of the protected areas that we have today in sub-Saharan Africa and in Latin America are carryovers of areas set aside by colonial governments,” said Brashares, “and for many researchers and for many communities, the creation of parks is seen to come at the cost of local communities.” Yet certain features can encourage people to move near protected areas, including:- Services made available by foreign assistance, such as health care, education, and livelihoods programs;
- Employment opportunities as park staff or in the tourism industry;
- Better ecosystem services, including food, water, wood, and traditional medicine;
- Easier access to markets, due to roads built to attract tourism; and
- Improved security provided by park guards and government staff.
Other features of protected areas deter migrants, including:
- Land-use restrictions;
- Conflict with wildlife (e.g., attacks on livestock and crops);
- Disadvantages associated with tourism, including higher cost of living and potential loss of cultural heritage;
- Isolation from urban centers; and
- Conflict with park staff, government representatives, or rural militias.
Higher Population Growth Near Protected Areas
Brashares and Wittemyer examined IUCN Category I and II protected areas in Africa and Latin America—which limit human activity within their boundaries—and excluded potentially confounding urban, marine, and new parks. Using UN Environment Programme population data from 1960-2000, they compared population growth in a 10-kilometer “buffer zone” surrounding each protected area with average rural population growth for that country. In 245 of the 306 parks they examined—and 38 of the 45 countries—population growth at protected-area edges was significantly higher than average national rural population growth.
Brashares and Wittemyer found three factors correlated with higher levels of population growth: more money for parks (as measured by protected-area funds from the Global Environment Facility); more park employees; and more deforestation on the edges of protected areas. Brashares emphasized, however, that there could be equally relevant correlations between population growth and employment in extractive industries, but that “the timber industry won’t give us their data and the mining industry and the oil industries aren’t so happy to share.” Thus, the study might inadvertently penalize NGOs and international organizations for their transparency.
Some researchers hypothesized that because protected areas are usually located in ecologically dynamic areas, this ecological wealth might be attracting new residents, rather than the protected areas themselves. But Brashares and Wittemyer found that proximity to a protected area, not general ecological abundance, was driving the trend. Others suspected that population grows at protected-area edges because the people who have been displaced by the creation of a park move to the park’s border. But population growth rates within the parks have been mostly stable or positive, so Brashares and Wittemyer doubt this is driving the trend.
Implications for Conservation
Brashares and Wittemyer outlined several policy implications of their research:- Emerging infectious diseases are a serious risk in areas with high human density close to wildlife populations, so governments and international organizations should try to limit potential outbreaks near protected areas.
- If the effectiveness of a protected area is measured by its ability to preserve biodiversity for generations, then community development programs must be executed carefully. For instance, roads and schools should not be built in an ecologically fragile corridor between two parks.
- Multi-use buffer zones that make core areas less accessible can allow individuals to continue to benefit from their proximity to nature while protecting biodiversity. “Some of the best protection of biodiversity is through isolation,” said Brashares.
Bremner took issue with some of Brashares’ and Wittemyer’s methods and conclusions; his full critique is available on the New Security Beat. Although Bremner agreed that migration—not natural increase—is likely driving higher population growth around protected areas, he believed the authors did not provide adequate evidence to demonstrate that this migration is driven by investments in conservation. “I hope that publishing this conclusion here in Science doesn’t provide our detractors, those who don’t want us to be spending on conservation, with the means to limit future spending for international conservation,” said Bremner.
