“From ‘youth bulges’ in the Muslim world to a population implosion in Russia to ‘premature aging’ in China, striking demographic trends the world over will reshape the future environment for U.S. policy,” says a new report from the Center for Strategic and International Studies, which aims to provide a comprehensive analysis of how demographic change will affect national and international security in the 21st century. As its title—The Graying of the Great Powers: Demography and Geopolitics in the 21st Century—indicates, the report focuses primarily on aging populations in developed countries, although one chapter does address the developing world.

The Graying of the Great Powers does a thorough job exploring the economic, geopolitical, and cultural implications of aging in Europe, Japan, and the United States, and it is to be praised for its readability and attention to concrete policy implications. But its focus on the developed world sometimes causes it to downplay the serious economic, socio-political, environmental, and security challenges posed by high population growth in developing countries—and by a global population that is expected to top 9 billion by 2050.

For instance, the authors use the past tense to refer to a time “when the prevailing worry was overpopulation.” Now, the word “overpopulation,” with its implication that some of us should not be here, is somewhat problematic. Nevertheless, it is clear that today, billions of human beings are consuming record amounts of natural resources at unsustainable rates—witness Yemen, where current annual water use is 30 percent greater than renewable water resources. Furthermore, many of the countries least able to provide employment and health care to their citizens have the highest population growth rates—for instance, Somalia and Afghanistan, which both have total fertility rates of 6.8 children per woman.

Wrapped up in their worries about the impact of low birth rates on armed services recruitment and government spending on pensions and health care for the elderly, the authors seem to forget what is actually at stake here: a woman’s decision to give birth to a child. Politicians can institute reforms that will make having children an easier proposition, but they should not pressure people to have children because they wish to avoid geopolitical upheaval. Ultimately, wanting to have a child is the only good reason to bring one into the world.

Burma’s ruling military junta is prohibiting almost all foreign aid workers from entering the country, despite the massive devastation wreaked by Cyclone Nargis last week. The military has also impounded an aid shipment from the UN World Food Program (WFP) and has refused aid from the United States, among other countries. “We are very concerned that this food is not reaching—on day six after a cyclone—the very victims of that cyclone,” said WFP spokesman Paul Risley. The United Nations has suspended aid to Burma pending resolution of the situation.

In a statement released earlier this week, the junta said it would be willing to accept foreign aid, as long as it could distribute the shipments itself. But so far, the statement has not matched up with reality.

The official death toll from the cyclone is approximately 23,000, but experts say this figure could rise significantly, as approximately 40,000 people remain missing. Hundreds of thousands are currently without shelter, food, safe water, or medical care, and international experts agree that the Burmese military does not have the capacity to meet the need. Further compounding the problem, Burma’s military rulers have pressed on with plans to conduct a national constitutional referendum in the less-affected areas tomorrow. Soldiers who could be delivering much-needed aid to survivors have instead been assigned to guard and run polling places. The ruling generals claim that approval of the referendum will set Burma on a gradual path to democracy; nearly all other observers say the vote is a sham. “If you believe in gnomes, trolls and elves, you can believe in this democratic process in Myanmar,” said chief UN human rights investigator Paulo Sergio Pinheiro last year.

Many of Burma’s citizens are probably too preoccupied with immediate survival right now to be thinking about protesting the junta’s delay of humanitarian relief. But in a few weeks or months, when the situation has (hopefully) stabilized somewhat and word has spread of the holdup of humanitarian aid, one wonders whether the junta will find itself the target of popular outrage. By dragging their feet on international humanitarian relief, Burma’s military rulers seem to be begging for an uprising.

Climate change will create hard security problems—including increasingly frequent and severe natural disasters, pandemic disease, desertification, and mass migration—but these challenges will not have hard security solutions, argues Nick Mabey in Delivering Climate Security: International Security Responses to a Climate Changed World (subscription or purchase required), a policy paper published by the Royal United Services Institute for Defence and Security Studies. Instead, policymakers, NGOs, the private sector, and the security community will need to develop nontraditional, innovative policies and programs to mitigate these threats.

Mabey, who served as a senior adviser in the UK Prime Minister’s Strategy Unit before becoming founding director and chief executive of E3G, an NGO working on sustainable development, thoughtfully outlines the security challenges that many previous reports on climate security (including by the CNA Corporation and the Center for Strategic and International Studies and the Center for a New American Security) have discussed. But he also examines several less frequently mentioned risks. For instance, he warns that some countries will try to use the need for renewable energy as a cover for obtaining nuclear technology for military purposes. Mabey argues that the development and dissemination of less risky energy technologies is the best way to prevent the proliferation of nuclear weapons.

In addition, Mabey notes, if the international system fails to address the threat of climate change effectively, its legitimacy will be undermined, and it will find it more difficult to resolve other global threats.

Mabey also calls our attention to the critical role that the environment plays in post-conflict reconstruction and peacebuilding efforts. Strategic planners developing 10-15-year security strategies for Afghanistan based on sustainable livelihoods must take climate change into account. Attempts to use a “hearts and minds” strategy against Islamist extremism may fall short as higher temperatures and lower rainfall dry up some of the main sources of jobs for young men in the Middle East and North Africa. In addition, Mabey notes, terrorists are likely to use climate change to feed existing grievances; Osama bin Laden has already spoken several times on climate change’s unequal impacts on different parts of the globe.

“Information on present and future serious climate security impacts is as good, if not better, than other information routinely used in security planning and assessment,” asserts Mabey. Therefore, he argues, the security community has no excuse for not planning for the worst-case climate change scenarios, just as it plans for the worst-case terrorism and nuclear weapons proliferation scenarios. Yet Mabey believes the international response to climate change so far has been “slow and inadequate.” He urges nations and international institutions to devote far greater resources to addressing the myriad threats it will pose to political stability and human well-being.

An article in today’s Washington Post explores the interconnected problems of poverty and rapid population growth in the Philippines. Many factors contribute to the country’s high poverty rate, including corruption and traditional land ownership laws, but a birth rate that is among the highest in Asia is also significant. Eighty percent of the Filipino population is Catholic, and both the influential Catholic Church and the current government—in power for the last five years—oppose modern family planning methods. Filipinos are permitted to buy contraception, but no national government funds may be used to purchase contraception for the millions who want it but cannot afford it.

The situation may be poised to worsen, notes the Post: “Distribution of donated contraceptives in the government’s nationwide network of clinics ends this year, as does a contraception-commodities program paid for by the U.S. Agency for International Development. For years it has supplied most of the condoms, pills and intrauterine devices used by poor Filipinos.”

Yet the story is not entirely gloomy. A recent brief by Joan Castro and Leona D’Agnes of PATH Foundation Philippines, Inc. describes IPOPCORM, a development program that has successfully delivered family planning services to impoverished Filipino communities while simultaneously promoting environmental conservation and overall human health. Based on this success, some municipal governments in IPOPCORM’s service areas have set aside money in their budgets to purchase family planning commodities directly. A major conference in 2008 (building on an earlier conference in 2006) addressed population, health, and environment connections in the Philippines; featured speakers included former Congressman Nereus Acosta and Joan Castro.

Yesterday, in a post on his Dot Earth blog, New York Times science reporter Andrew Revkin called attention to the fact that 2.6 billion people lack access to sanitation facilities—and that includes pit latrines, not just flush toilets. The World Health Organization estimates that inadequate water, sanitation, and hygiene are responsible for 4 percent of all deaths worldwide and 5.7 percent of the total global disease burden (including premature death and years lost to disability caused by disease). Children are the most acutely affected by poor sanitation: 1.5 million children die each year from diseases—primarily diarrhea—caused by inadequate sanitation.

Tomorrow is World Water Day, and in honor of 2008 being the International Year of Sanitation, the United Nations and other organizations will strive to raise people’s awareness of sanitation, combat the taboos against discussing it, and galvanize efforts to halve the number of people without access to sanitation by 2015—a Millennium Development Goal.

The Environmental Change and Security Program’s (ECSP) Navigating Peace Initiative seeks to call attention to the importance of water and sanitation issues. ECSP’s Water Stories Flash website includes a multimedia presentation on dry sanitation in Mexico, while “Low-Cost Sanitation: An Overview of Available Methods,” an article by Alicia Hope Herron in ECSP’s recent report Water Stories: Expanding Opportunities in Small-Scale Water and Sanitation, analyzes the pros and cons of the numerous inexpensive, innovative sanitation technologies currently available.

A senior wildlife official with the Congolese Institute for the Conservation of Nature (ICCN) was arrested this week amid charges that he organized the executions of up to 10 endangered mountain gorillas in Virunga National Park last year. The official is also accused of cutting down protected trees to convert them into charcoal. WildlifeDirect, a wildlife conservation NGO that works in the park, suggested that Mashagiro had orchestrated the killings of the gorillas to distract rangers from the charcoal production, which was destroying the gorillas’ habitat, and to discourage the rangers from protecting the gorillas.

Last month, the New Security Beat reported on a new agreement between the Democratic Republic of the Congo (DRC), Uganda, and Rwanda to protect the mountain gorillas’ rapidly diminishing habitat. The initiative was one of the few promising developments for the gorillas over the past several months.

In early March, rebels who had taken control of the park’s Gorilla Sector—home to half of the world’s approximately 720 gorillas—threatened to kill any park ranger who attempted to enter it. According to local officials, the rebels have set up a parallel gorilla administration in the sector, charging tourist groups to view the gorillas. The park rangers had hoped they would be permitted to enter the Gorilla Sector following a January 2008 peace agreement between the Congolese government and the rebel groups, but the rebels have continued to forbid them from returning to the area.

A European Union (EU) report released ahead of a major EU summit on March 13-14 warns that climate change is likely to create or worsen a host of local, regional, and global security challenges. “Climate change is best viewed as a threat multiplier which exacerbates existing trends, tensions and instability,” says the report.

The Kenyan army launched a major assault on the Sabaot Land Defence Force (SLDF) yesterday, said officials. More than 500 people have been killed in land clashes involving the SLDF over the past year and a half, including 13 last week.
