“The road to inaction is paved with research reports,” said Marya Khan, our Population Reference Bureau facilitator, opening today’s East Africa Population-Health-Environment (PHE) Network workshop on bridging the research-to-policy gap.

Rwandan Minister of Natural Resources Stanislas Kamanzi officially launched the meeting of the East Africa PHE Network this morning, stating that Rwanda’s highest-in-Africa population density of 365 people per square kilometer—which he argued leads to environmental degradation and poor human health in both rural and urban areas—compels an integrated approach to development. Kamanzi said that Rwanda’s National Environment Policy and national development plan, Vision 2020, both recognize population-health-environment (PHE) links, and he expressed Rwanda’s commitment to implementing the recommendations of the First Inter-ministerial Conference on Health and Environment in Africa, which was co-hosted by the World Health Programme and the UN Environment Programme in Gabon in August 2008.

“Human-animal conflicts have assumed alarming proportions in the region,” Asghar Inayati, a regional wildlife warden in Kashmir, recently told Inter Press Service (IPS) News. Since India and Pakistan gained independence in 1949, both sides have fought for control of the territory. Not only has the decades-long conflict claimed 100,000 lives (by some estimates), it has also displaced animals from their natural habitats, sparking violent encounters with local people and threatening many species’ survival.

An article in Conservation Letters examining the effect of war on wildlife in Cambodia finds that “the legacy of conflict for wildlife can be profound and destructive. To address post-conflict challenges more effectively, conservation must be integrated within broader peacebuilding processes, including disarmament, demobilization, and reintegration of combatants.”

New York Times environmental reporter Andrew Revkin shares a recent nightmare on his blog, Dot Earth: If human beings achieve inexpensive, renewable energy, will this spur environmentally destructive population growth and consumption?

“Today, one-third of the world’s population has to contend with water scarcity, and there are ominous signs that this proportion could quickly increase,” writes the International Water Management Institute’s David Molden in the BBC’s Green Room. “Up to twice as much water will be required to provide enough food to eliminate hunger and feed the additional 2.5 billion people that will soon join our ranks. The demands will be particularly overwhelming as a wealthier, urbanised population demands a richer diet of more meat, fish, and milk.”

“Climate Wars” is a three-part podcast series by the Canadian Broadcasting Corporation.

Circle of Blue has launched the online radio series “5 in 15”; one episode features water expert Peter Gleick, head of the Pacific Institute, while another highlights Mark Turrell, CEO of technology company Imaginatik.

“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.

“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.”

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.
