Joel Cohen, a renowned population expert and professor at Columbia and Rockefeller universities, recently gave a lecture simply titled “Meat.” As it was co-sponsored by the International Food Policy Research Institute and the Population Reference Bureau, I was hoping for an insightful discussion of meat eating and its implications for feeding a world of nine billion. While I think Cohen avoided the question of whether meat eating is ultimately sustainable, I was pleased that he included two key insights: the potential for family planning services to contribute to food security, and the importance of using multidisciplinary approaches to solve today’s global problems.

Family Planning for Food Security

In working to improve food security, Cohen said policymakers and practitioners need to focus on those who are most vulnerable. To this end, he identified five groups and suggested targeted policies for each:

While the healthy eating policies will not surprise food security experts, his recommendations on family planning might. He highlighted what should be–but is not always–apparent: that tackling food security without thought for family planning is like attempting to fill an empty bucket without first plugging the holes.

Feeding the one billion hungry people in the world today is an enormous challenge that cannot be met by any single policy. Instead, it will take an array of partial solutions, and offering family planning services to women and young people is an important part of the package. Such projects can help reduce the number of children being born into hunger by allowing women and couples to assess their economic and food situations and plan according to their needs and wishes. Voluntary family planning services and materials will not solve the food security challenge on their own, but they can make it more manageable, especially in the long run.

Family planning’s potential contribution to food security is just one part of Cohen’s larger take-home message: population, economics, environment, and culture all interact. To meet today’s multidisciplinary challenges, single-sector approaches are not up to task.

The Many Faces of Meat

Cohen offered two competing perspectives on meat eating. On the one hand, average global meat production generates a fraction of the calories and protein, per unit of land, that could be derived from plant sources. It is likely the “largest sectoral source of water pollution,” said Cohen, and is at least partly responsible for the spread of over a dozen zoonotic diseases. It contributes to only 1.4 percent of world GDP while comprising 8 percent of world water consumption.

These hidden “virtual water” costs made headlines in Britain the other week, when a study on global water security published by the Royal Academy of Engineering popularized the Water Footprint Network’s earlier findings that that an average kilogram of beef requires 15,500 liters of water–over eight times the volume needed to produce the equivalent weight in soybeans and greater than 10 times that needed for the equivalent amount of wheat.

On the other hand, Cohen pointed out that meat production provides livelihoods for an estimated 987 million of the world’s rural poor, and has important cultural significance in many societies. And it can provide many essential nutrients, even in small doses.

In one study he cited, children living in Kenya who were provided 1 ounce of meat a day received 50 percent of their daily protein requirements and showed greater increases in physical activity and development, verbal and arithmetic test scores, and initiative and leadership behaviors as opposed to students who received the calorie-equivalent in milk or fat.

The Four Factors: Population, Economics, Environment, and Culture

Clearly, Cohen’s four factors all come in to play when evaluating meat’s role in food security. An analysis of any global health issue that looks at only one factor would miss indispensable parts of the problem.

“Population interacts with economics, environment, and culture,” Cohen concluded. “If you use that checklist when somebody gives you a simple-minded solution to a problem, you can save yourself a lot of simple-minded thinking.”

“Nature is something that is both vulnerable and valued,” Paul Collier said yesterday at the World Bank. “It is being mismanaged…what it has turned into is a series of environmental battles between environmentalists and economists.”

Collier was giving the first public presentation of of his new book, The Plundered Planet: Why We Must—and How We Can—Manage Nature for Global Prosperity. In it, he asserts that disputes between environmentalists and economists often arise from a fundamental misunderstanding on both sides about the unique qualities and purposes of “natural assets.” This misunderstanding, he says, has created a state of natural plunder. In Plundered Planet, Collier elucidates the ethical and economic considerations for the proper management of natural assets, how a greater understanding of natural assets and better environmental management can be achieved, and lessons for development.

Paul Collier will be joining ECSP for an in-depth discussion of Plundered Planet, economics, and development at the Wilson Center in June. Until then, for a more detailed look, check out the New Security Beat’s previous coverage of Collier’s book preview with Nancy Birdsall, president of the Center for Global Development, at the U.S. Institute of Peace.

“Women, Gender Equality and Climate Change,” a fact sheet released by the United Nations WomenWatch, is a cache of information for those interested in climate change’s differentiated impacts on the sexes. The fact sheet synthesizes data from many sources, mostly UN, into concise sections on food security, biodiversity, water, health, human rights, energy, natural disasters, migration, and adaptation–including financing projects and the development of new technology. While brief, each section is well-sourced and offers a list of links to relevant UN publications and websites.

Promoting the Dialogue: Climate Change and U.S. Ground Forces, a new working paper by Christine Parthemore of the Center for New American Security (CNAS), delves into how climate change will affect future operating environments, related missions, equipment, and capabilities of U.S. ground forces. The working paper, part of “Promoting the Dialogue” series, is based on interviews, research, and site visits. The paper follows Promoting the Dialogue: Climate Change and the Maritime Services, also by Parthemore, and a publication on climate change’s implications for air missions is forthcoming. Parthemore concludes with recommendations for areas of future research and a call for “[d]eeper intellectual study of how climate change is likely to affect the U.S. ground forces.”

United States Southern Command (SOUTHCOM) has publicly released a Google Earth-based mapping system, 3D User Defined Operational Pictures (UDOP) (Google Earth plug-in required), aiming to help emergency personnel and donors better respond to humanitarian crises.

Currently, UDOP maps are available for responses in Haiti and Chile. Data layers uploaded by SOUTHCOM and others can be toggled on and off and depict an array of information, from earthquake intensity maps to a 3D model of Haiti’s collapsed presidential palace. Other layers mark:

“Political Marginalization, Climate Change, and Conflict in African Sahel States,” authored by Clionadh Raleigh and appearing in the March 2010 issue of International Studies Review, examines the relationship between political status, economic status, and conflict among African communities threatened by climate change. “[T]he risk of conflict depends largely on the size and political importance of ethnic groups,” Raleigh finds. “Small, politically insignificant ethnic groups experience most conflicts related to environmental pressures.” The work is geared toward helping practitioners predict where high levels of vulnerability and conflict may occur in the face of climate change.

“The Department of Defense is not the U.S. government lead for climate change, but we certainly can show leadership in this area,” Deputy Assistant Secretary of Defense for Strategy Amanda Dory recently told an audience at the Woodrow Wilson Center. “That’s true of energy as well.”

Worldfocus recently featured two pieces on the Arab world’s burgeoning population. “Demographics of the Arab World,” a radio broadcast, brings together Magda Abu-Fadil of the American University in Beirut and Bernard Haykel of Princeton University for a look at the region’s demographic trends. Despite possessing different political systems and being at different levels of economic development, demographic challenges of youth bulges, emigration, and gender gaps are common to countries across the Arab world. “Arab World Experiences Rapid Population Explosion,” a written interview with demographer Patrick Gerland of the United Nations Population Division, tackles similar issues. Topics of discussion include demographic variations between Middle Eastern nations, fertility rates, the consequences of the region’s youth bulge, and best- and worst-case scenarios for the Arab world’s future.
