Climate Science, Military and Gender Roles, and the Tibetan Plateau
›September 14, 2010 // By Geoffrey D. DabelkoHere are some useful links to environment, population, and security work that recently crossed my desk.
• Need a break from the raging debate set off by Halvard Buhaug’s Proceedings of the National Academy of Sciences quantitative-based critique of climate and African civil war linkages (or lack thereof)? Check out some of the correlations Cullen Hendrix and Idean Salehyan of University of North Texas find in their piece “After the Rain: Rainfall Variability, Hydro-Meteorological Disasters, and Social Conflict in Africa.”
• A German military think tank report worries about the economic and political implications of peak oil over a relatively short time frame.
• Militaries’ humanitarian responses to extreme weather events rather than actual shooting wars are the focus of “The Coming Conflicts of Climate Change,” by U.S. Navy Foreign Area Officer Michael Baker. Baker is writing for the Council on Foreign Relations as one of their International Affairs Fellows.
• Oxfam America and IUCN staff experts call for greater consideration of different gender roles in addressing climate change. UN climate institutions are targeted in the IPS story.
• Journalist Steve Solomon highlights the high politics of transboundary water in Asia with a piece in Forbes. China’s control of the Tibetan water tower with massive dam building amps up the pressure in South and Southeast Asia.
• Canadian scholar Eric Kaufmann’s book, Shall the Religious Inherit the Earth? breaks down relative population growth rates between the religious and the secular. One is high, one is below replacement level. So far the book is only published in Europe but you can get it from Amazon UK.
• The highly respected science journal Nature editorializes against the rising tide of loud anti-science demagoguery. Strong words on the U.S. political context.

Climate-Security Linkages Lost in Translation
›A recent news story summarizing some interesting research by Halvard Buhaug carried the headline “Civil war in Africa has no link to climate change.” This is unfortunate because there’s nothing in Buhaug’s results, which were published in the Proceedings of the National Academy of Sciences, to support that conclusion.
In fact, the possibility that climate change might trigger conflict remains very real. Understanding why the headline writers got it wrong will help us better meet the growing demand for usable information about climate-conflict linkages.
First, the headline writer made a simple mistake by translating Buhaug’s modest model results — that under certain specifications climate variables were not statistically significant — into a much stronger causal conclusion: that climate is unrelated to conflict. A more responsible summary is that the historical relationship between climate and conflict depends on how the model is specified. But this is harder to squeeze into a headline — and much less likely to lure distracted online readers.
Buhaug tests 11 different models, but none of the 11 corresponds to what I would consider the emerging view on how climate shapes conflict. Using Miguel et al. (2004) as a reasonable representation of this view, and supported by other studies, there seems to be a strong likelihood that climatic shocks — due to their negative impacts on livelihoods — increase the likelihood that high-intensity civil wars will break out. None of Buhaug’s 11 models tested that view precisely.
If we are going to make progress as a community, we need to be specific about theoretically informed causal mechanisms. Our case studies and statistical tests should promote comparable results, around a discrete number of relevant mechanisms.
Second, a more profound confusion reflected in the headline concerns the term “climate change.” Buhaug’s research did not look at climate change at all, but rather historical climate variability. Variability of past climate is surely relevant to understanding the possible impacts of climate change, but there’s no way that, by itself, it can answer the question headline writers and policymakers want answered: Will climate change spark more conflict? For that we need to engage in a much richer combination of scenario analysis and model testing than we have done so far.
We are in a period in which climate change assessments have become highly politicized and climate politics are enormously contentious. The post-Copenhagen agenda for coming to grips with mitigation and adaptation remains primitive and unclear. Under these circumstances, we need to work extra hard to make sure that our research adds clarity and does not fan the flames of confusion. Buhaug’s paper is a good model in this regard, but the media coverage does not reflect its complexity. (Editor’s note: A few outlets – Nature, and TIME’s Ecocentric blog – did compare the clashing conclusions of Buhaug’s work and an earlier PNAS paper by Marshall Burke.)
The stakes are high. This isn’t a “normal” case of having trouble translating nuanced science into accessible news coverage. There is a gigantic disinformation machine with a well-funded cadre of “confusionistas” actively distorting and misrepresenting climate science. Scientists need to make it harder for them to succeed, not easier.
Here’s how I would characterize what we know and we are trying to learn:1) Economic deprivation almost certainly heightens the risk of internal war.
To understand how climate change might affect future conflict, we need to know much more. We need to understand how changing climate patterns interact with year-to-year variability to affect deprivation and shocks. We need to construct plausible socioeconomic scenarios of change to enable us to explore how the dynamics of climate, economics, demography, and politics will interact and unfold to shape conflict risk.
2) Economic shocks, as a form of deprivation, almost certainly heighten the risk of internal war.
3) Sharp declines in rainfall, compared to average, almost certainly generate economic shocks and deprivation.
4) Therefore, we are almost certain that sharp declines in rainfall raise the risk of internal war.
The same scenarios that generate future climate change also typically assume high levels of economic growth in Africa and other developing regions. If development is consistent with these projections, the risk of conflict will lessen over time as economies develop and democratic institutions spread.
To say something credible about climate change and conflict, we need to be able to articulate future pathways of economics and politics, because we know these will have a major impact on conflict in addition to climate change. Since we currently lack this ability, we must build it.Marc Levy is deputy director of the Center for International Earth Science Information Network (CIESIN), a research and data center of the Earth Institute of Columbia University.

The Future of Sub-Saharan Africa’s Tentative Fertility Decline
›August 25, 2010 // By Richard CincottaIn her recent post on The New Security Beat, Jennifer Sciubba argues that the medium-fertility variant projection published in the UN Population Division’s biennial projections — the source of most future data published in the Population Reference Bureau’s 2010 World Population Data Sheet — forecasts an unrealistically low total fertility rate (TFR) for sub-Saharan Africa in 2050, at a rate of 2.5 lifetime childbirths per woman.

Climate Change Adaptation and Mitigation in the Agricultural Sector
›“Climate Change and China’s Agricultural Sector: An Overview of Impacts, Adaptation and Mitigation” from the International Centre for Trade and Sustainable Development (ICTSD) explores mitigation and adaptation strategies to avoid the worst effects of climate change in China’s farming sector. The authors, Jinxia Wang, Jikun Huang and Scott Rozelle, point out that, although often overlooked in favor of the industrial sector, a disproportionate amount (greater than 15 percent) of China’s greenhouse gas emissions come from agriculture. Challenges include over-fertilization, high methane levels, water pollution, and water scarcity. Wang, Huan, and Rozelle predict that trade “can and should be used to help China mitigate the impacts of climate change” and programs promoting better calibration of fertilizer dosages and “conservation tilling” practices will help farmers reduce emissions.
Also from ICTSD comes another study on climate adaptation and mitigation, this time focusing on the developing world. Globally, agriculture accounts for only 4 percent of GDP but according to the IPCC it also accounts for more than 25 percent of greenhouse gas emissions, making climate adaptation and mitigation in the sector particularly important. “Agricultural Technologies for Climate Change Mitigation and Adaptation in Developing Countries: Policy Options for Innovation and Technology Diffusion” by Travis Lybbert and Daniel Sumner examines some of the more promising innovations that may help those countries most vulnerable to climate change to cope with and minimize risk. The authors suggest that most policies that target economic development and poverty reduction will also naturally lead to improvements in agriculture, accordingly most of their recommendations center around improving market efficiency, communication of technologies and best practices, and investment in research and development. -
Floods, Fire, Landslides, and Drought: The Guardian’s “Weather Crisis 2010”
›From the Guardian’s DataBlog comes an excellent overview of some of the extreme weather affecting the globe this summer, from the devastating floods in Pakistan which have inflicted “huge losses” to crops and exacerbated an already tenuous security situation, to the wildfires in Russia which have smothered the capital in dangerous smog and crippled domestic wheat supplies.
“Global temperatures in the first half of the year were the hottest since records began more than a century ago,” writes author and graphic artist Mark McCormick.
The orange areas of the map represent high pressure systems and the blue, low pressure systems, which as explained by Peter Stott of the Met Office, are important indicators of the rare climatic conditions that caused this summer’s abnormal conditions across Eurasia.
The flooding in Pakistan has garnered the most international attention, having now affected more people than the 2004 tsunami, 2010 Haiti earthquake, and 2005 Kashmir earthquake combined. Other highlighted areas of the map include flooding in Poland and Germany, drought in England, mudslides in Latin and South America, record-breaking drought and hunger in West Africa, and flooding and landslides in China, which recently pushed the world’s largest hydroelectric dam to its limit and have now been blamed for more than 1,000 deaths.
Although it does a good job highlighting the frequency and severity of extreme weather events this summer, it’s important to note that the map only covers events in July and August. That leaves out the “1000-year” floods in Tennessee this May as well as the heavy snowfall seen in the Northeast United States and the winter of “white death” in Mongolia earlier this year, which also severely disrupted local and national infrastructure as well as a great many people’s livelihoods.

Misguided Projections for Africa’s Fertility
›By assuming that sub-Saharan Africa’s total fertility rate will decrease to 2.5 children per woman by 2050, the most recent population projections issued by the Population Reference Bureau likely continue to underestimate fertility for Africa. Though northern Africa has significantly lowered fertility, sub-Saharan Africa’s TFR is still 5 children per woman. Achieving the levels projected by PRB or the United Nations will largely depend on whether the conditions that led to past fertility declines for other states can be established in sub-Saharan Africa.
Demographers have identified numerous factors associated with fertility decline, including increased education for females, shifting from a rural agricultural economy to an industrial one, and introduction of contraceptive technology. Sub-Saharan Africa is only making slow progress in each of these areas.
Surveying Obstacles to Development
Primary school enrollment is up, but the pace of improvement is declining. Meanwhile, gender gaps persist: Enrollment for boys remains significantly higher than for girls. Girls’ education is associated with lower fertility, partly because education helps women take charge of their fertility and also because education influences employment opportunities. Increased female labor force participation has been shown to increase the cost of having children, and is therefore associated with initial fertility declines.
Disease is one wildcard for Africa that limits the utility of past models of demographic transition in the African context. HIV/AIDS is decimating sub-Saharan Africa’s adult workforce and creating shortages of teachers that will impede future efforts to boost primary school enrollment. According to the United Nations, the number of teachers in sub-Saharan Africa needs to double in the next five years to reach Millennium Development goals.
Development that would shift the region’s economies from agriculture to industry is also lagging. While several West African countries are seeing some gains, the African continent on the whole faces major structural impediments to development. In The Bottom Billion, Paul Collier points out that many of these countries may have “missed the boat” to attract investment and industry that would pull the region out of poverty, partly because the least developed countries are still not cost-competitive enough when compared with current centers of manufacturing, like China.
Finally, there remains a high unmet need for family planning. One in four women aged 15 to 49 who are married or in union –- and who have expressed an interest in using contraceptives — still do not have access to family planning tools. In general, maternal mortality remains high and adolescents in the poorest households are three times more likely to become pregnant and give birth than those in the richest households, according to the most recent UN Millennium Development Goals report.
Sub-Saharan Africa: Off the Radar?
Sub-Saharan Africa suffers from a lack of attention by the international community and lack of political capacity at home. Many countries in the region are plagued by civil strife and poor governance, and developed countries continue to fall short of development assistance pledges. There is not the same sense of urgency today among developed countries about the global population explosion as there once was. Cold War politics and the environmental and feminist movements motivated much of the study of fertility and funding of population programs during the second half of the 20th century. Attention by governments and NGOs sped the fertility transition among many countries.
Today, the world’s wealthiest countries are not concerned primarily with Africa’s problems, but rather are more concerned with their own population decline and with the national security implications of population trends in areas associated with religious extremism. The recession has further hindered the flow of development funds.
Fertility is the most difficult population component to predict, and demographers must draw on the experiences of other regions to inform assessments of Africa’s population patterns. Demographers seem to be overconfident that Africa’s fertility will follow the pattern of recent declines, particularly in Latin America, which were more rapid than Western Europe’s decline due to the diffusion of technology and knowledge.
Once states begin the demographic transition towards lower fertility and mortality, they have tended to continue, with few exceptions. Therefore, most projections for Africa assume the same linear pattern of decline will hold. Yet, the low priority of Africa’s population issues among the world’s wealthiest states, combined with shortfalls in education, development, and contraception, may mean that the demographic transition in Africa will be slower than predicted.
Projections are useful to give us a picture of what the world could look like if meaningful policy changes are made. In the case of sub-Saharan Africa, prospects for these projections are dim.

How Maternal Mortality and Morbidity Impact Economic Development
›“Investing in women and girls is the right thing to do,” says Mayra Buvinic, sector director of the World Bank’s gender and development group. “It is not only fair for gender equality, but it is smart economics.” But while it may be smart economics, many developing countries fail to address the underlying social causes that impact economic growth, such as poverty and gender inequality. Buvinic was joined by Dr. Nomonde Xundu, health attaché at the Embassy of South Africa in Washington, D.C., and Mary Ellen Stanton, senior maternal health advisor at the U.S. Agency for International Development (USAID), at the sixth meeting of the Advancing Policy Dialogue on Maternal Health Series, which addressed the economic impact of maternal mortality and provided evidence for the need for increased investment in maternal health.

Land, Education, and Fertility in Rural Kenya
›August 10, 2010 // By Wilson Center StaffExcerpted from a summary on the Population Reference Bureau‘s website, by Karina Shreffler and F. Nii-Amoo Dodoo. The original version of this article appeared in Population and Environment 30, no. 3 (2009): 75-92.
Little is known about the role of land inheritance in the link between land availability and fertility. The recent transition from high to lower levels of fertility in some African countries presents an opportunity to clarify the underlying causes of this decline, since the individuals involved in the transitions are still alive.
Using data from focus group discussions with people whose childbearing occurred before and during the rapid and unexpected fertility decline in Nyeri District in rural Kenya, we examined the impact of diminishing land availability, farm size, and inheritance patterns on fertility decisionmaking and behavior. The results shed new light on the role of education, long considered the key determinant of fertility transition.
Our research suggests that rather than inheritance being an external factor affecting fertility behavior, parents in Nyeri District chose to educate their children after realizing they would not be able to bequeath a sufficient amount of land. Our work provides evidence of the importance of considering the influence of environmental factors on demographic processes, particularly in regions of resource dependence.
