  • Redrawing the Map of the World’s International River Basins

    ›
    Guest Contributor  //  August 24, 2011  //  By Jim Duncan

    Understanding why conflict over water resources arises between nations begins with a solid understanding of the geography of international river basins. Where are the basins? How big are they? How many people live there? Who are the riparian nations, and what is the significance of each to the basin?

  • Youth Bulge and Societal Conflicts: Have Peacekeepers Made a Difference?

    ›
    August 22, 2011  //  By Richard Cincotta
    Until recently, the question of which countries are at the most risk of violent societal conflict could be answered with a terse, two-part response: “the young and the war-torn.” This simple characterization regarding youth and conflict worked well, until the first decade of the 21st century. The proportion of youthful countries experiencing one or more violent intrastate conflicts declined from 25 percent in 1995 to 15 percent in 2005. What’s behind this encouraging slump in political unrest? One hypothesis is that peace support operations (PSOs) – peacekeepers, police units, and specialized observers that are led, authorized, or endorsed by the United Nations – have made a difference.

    From the 1970s through the 1990s, more than 90 percent of all societal conflicts broke out in countries with a youthful age structure – a population with a median age of 25 years or less. And wherever civil and ethnic wars emerged, they tended to persist. The average societal conflict that began between 1970 and 1999 continued without a one-year break in battle-associated fatalities for about six years. Some – including the Angolan civil war, Northern Ireland’s “Troubles,” Peru’s war against the Shining Path, and the Afghan civil war – endured for decades. In contrast, inter-state conflicts that began between 1970 and 1999 lasted, on average, less than two years (see the UCDP/PRIO Conflict Database).

    Taking on Intra-State Conflicts

    Beginning in the early 1990s, however, there was a marked expansion in size and number of PSOs deployed in the aftermath of societal warfare, which appears to have dampened the persistence of some conflicts and prevented the reemergence of others. The annual number of active PSOs deterring the re-emergence of societal conflict jumped from just 2 missions during 1985 to 22 in 2005. In contrast, those led, authorized, or endorsed by the UN to maintain cease-fire agreements between neighboring states during that same period only increased from three active missions to four. By 2009, nearly 100,000 peacekeepers were stationed in countries that had recently experienced a societal conflict. About 70 percent were deployed in countries with a youthful population (see Figures 2A and B). Why the sudden expansion in use of PSOs?

    According to William Durch and Tobias Berkman, this upsurge was less a change of heart or modification of a global security strategy and more an outcome of the unraveling web of Cold War international relations. Before the 1990s, the majority of PSOs were United Nations-led operations that were mandated to monitor or help maintain cease-fires along mutual frontiers. Because insurgents were typically aligned with either the Soviets or a Western power, Security Council authorization to mediate a societal conflict was difficult to secure.

    This situation changed with the breakup of the Soviet Union and the initiation of PSOs by regional organizations, including operations by the Economic Community of West African States (ECOWAS) in Liberia and Sierra Leone and the NATO-led Kosovo Force in 1998-99.

    Demographic Forecasting

    What do national demographic trends suggest for the demand for PSOs over the next two decades? For societal conflict, political demographers foresee that the demand for PSOs will continue to decline among states in Latin America and the Caribbean – with the exception of sustained risk in Guatemala, Haiti, Bolivia, and Paraguay. Similarly, demand for peacekeeping is expected to continue to ebb across continental East Asia.

    Gauged by age structure alone, the risk of societal warfare is projected to remain high over the coming two decades in the western, central, and eastern portions of sub-Saharan Africa; in parts of the Middle East and South Asia; and in several Asian-Pacific island hotspots – Timor-Leste, Papua New Guinea, the Philippines, and Solomon Islands. But even in some countries that are losing their youthful blush, domestic political relations could turn out less rosy than this simple age-structural model forecasts.

    In other words, there are roadblocks to a “demographic peace.” Among them is an increasing propensity for a specific demographic configuration of ethnic conflict: warfare between state forces and organizations that recruit from a minority that is more youthful than the majority ethnic group. Examples of these conflicts include the Kurds in Turkey, the Shiites in Lebanon, the Pattani Muslims in southern Thailand, and the Chechens of southern Russia.

    However, this twist on the youth bulge model of the risks of societal conflict is a discussion for another installment on New Security Beat. Suffice it to say that when political demographers look over the UN Population Division’s current demographic projections, they see few signs of either the waning of societal warfare, or the withering of the current level of demand for PSOs.

  • The Role of Faith-Based Organizations in Maternal and Newborn Health Care

    ›
    Dot-Mom  //  From the Wilson Center  //  August 18, 2011  //  By Roza Essaw
    Government and nongovernmental organizations have consistently played a key role in addressing maternal mortality. While these initiatives are well documented, the role of faith-based organizations (FBOs) in maternal and newborn health is less well understood.

    In November, the Wilson Center’s Advancing Policy Dialogue to Improve Maternal Health series will bring diverse institutions together such as the Pakistan Initiative for Mothers and Newborns (PAIMAN) and Pathfinder International to discuss country experiences and evaluate opportunities for overcoming challenges.

    According to the World Health Organization, FBOs own up to 70 percent of the health infrastructure in sub-Saharan African countries and often work in remote regions where government and NGO services are limited. FBO’s are critical to improving maternal health as they fill gaps in the health system – particularly in low-resource settings – and approaching culturally sensitive barriers that often prevent mothers from seeking health care.

    The level of trust communities place on their religious leaders explains one of the main reasons why FBOs are attaining success. A study conducted by Pew Charitable Trust found that a vast majority of people in sub-Saharan Africa identify themselves as adherents of Christianity or Islam, and approximately 75 percent trust their religious leaders.

    As partnerships with FBO’s increase, it is imperative that organizations share their lessons learned and identify capacity and knowledge gaps in order to improve effectiveness.

    Pakistan Initiative for Mothers and Newborns

    The Pakistan Initiative for Mothers and Newborns (PAIMAN), which started out as a six-year project funded by USAID and led by JSI Research and Training Institute, is a strong example of a program incorporating faith to improve maternal mortality rates. The project aims to ensure that women have access to skilled birth attendants during and immediately after giving birth. Additionally, the project focused on increasing the quality of care both in the public and health sectors. PAIMAN was able to achieve substantial success by utilizing various communication interventions such as mass media, community media, and advocacy efforts. One of the most successful initiatives PAIMAN organized was reaching out to 1,000 religious scholars, known as ulamas, to deliver frequent messages on maternal and newborn health care. Since its initiation, this project has “saved more than 30,000 newborn lives resulting in a 23 percent decrease in neonatal mortality,” according to their numbers.

    Pathfinder International

    Pathfinder International is another great example of an organization that has understood the value of FBOs and worked in collaboration with them to achieve results for maternal health. Pathfinder has worked in numerous countries including Nigeria, Ghana, Ethiopia, Egypt, Uganda, Kenya, and Bangladesh to educate religious leaders and communities on communication strategies for improving maternal health behaviors.

    In Ethiopia, Pathfinder organized over 250 religious leaders representing the Orthodox Christian, Catholic, Protestant, Seventh Day Adventist, Mekaneyesus Christian, and Muslim faiths to educate them about maternal mortality. At the conclusion of the seminar, the religious leaders agreed to condemn a host of harmful traditional practices, including female genital cutting, marriage by abduction, early marriage, rape, and unsafe abortion and agreed that they are not required by the Bible or Korean. Religious leaders in Egypt also came to similar conclusions after participating in these types of seminars.

    “By helping religious leaders see the links between reproductive health and families’ well-being, Pathfinder enables them to become committed advocates for positive reform,” wrote Mary K. Burke, technical communications associate at Pathfinder International in the 2006 report, Advancing Reproductive Health and Family Planning through Religious Leaders.

    Challenges: Equipping and Encouraging

    Despite the prevalence of success stories among FBOs to improve maternal mortality, challenges do exist. For instance, although religious leaders are highly respected by their communities, their teachings become useless, as pointed out by a USAID-sponsored Extending Service Delivery Project report, unless they are also properly trained and equipped with the latest service delivery systems and scientific information.

    The report also describes the importance of cooperation and support from the government and decision-making representatives. If the private, public, and government sectors are fragmented and no formal recognition exists to acknowledge the work of religious leaders for improving maternal mortality, then success may be significantly hampered.

    To learn more about the role of faith-based organizations in women’s health, be sure to check out the Global Health Initiative event on FBOs coming in November, with representatives from PAIMAN, Pathfinder International, and others.

    The Hungry Planet: Global Food Scarcity in the 21st Century

    ›
    August 16, 2011  //  By Wilson Center Staff
    The original version of this article, by Russell Sticklor, appeared on World Politics Review.

    At the dawn of the 20th century, the world population was inching toward a modest two billion. In the 111 years since, notwithstanding the impact of war, genocide, disease, and famine, the global population has soared, reaching three billion around 1960 and now quickly approaching the neighborhood of seven billion. By 2050, the planet will likely be home to two billion more.

    We may not be witnessing the detonation of the “population bomb” that Paul Ehrlich warned of in his seminal 1968 book, but such rapid demographic change is clearly pushing the international community into uncharted territory. With a limited amount of arable land and a finite supply of fresh water for irrigation, figuring out how to feed a planet adding upward of 70 million people each year looms as one of the 21st century’s most pressing challenges.

    The push to ensure global food security transcends the desire to avoid repeating the famines that devastated the Soviet Union, China, North Korea, Ethiopia, and so many other corners of the world during the past century. Instead, aid and development organizations today rightly view food insecurity problems as deeply intertwined with issues of economic development, public health, and political stability, particularly in the developing world. To maintain order in the international community and prevent the emergence of new failed states in the decades ahead, it will be critical to find innovative means of feeding the rapidly growing populations of sub-Saharan Africa, the Middle East, and South and East Asia.

  • International River Basins: Mapping Institutional Resilience to Climate Change

    ›
    From the Wilson Center  //  August 15, 2011  //  By Kellie Furr
    Institutions that manage river basins must assess their ability to deal with variable water supplies now, said Professor Aaron Wolf of Oregon State University at the July 28 ECSP event, “International River Basins: Mapping Institutional Resilience to Change.” “A lot of the world currently can’t deal with the variability that they have today, and we see climate change as an exacerbation to an already bad situation.”

    Wolf and his colleagues, Jim Duncan of the World Bank and Matt Zentner of the U.S. Department of Defense, discussed their efforts to map basins at risk for future tensions over water, as identified in their coauthored World Bank report, “Mapping the Resilience of International River Basins to Future Climate Change-Induced Water Variability.” [Video Below]

    Floating Past the Rhetoric of “Water Wars”

    Currently, there are 276 transnational water basins that cross the boundaries of two or more countries, said Wolf. “Forty percent of the world’s population lives within these waters, and interestingly, 80 percent of the world’s fresh water originates in basins that go through more than one country,” he said. Some of these boundaries are not particularly friendly – those along the Jordan and Indus Rivers, for example – but “to manage the water efficiently, we need to do it cooperatively,” he said.

    Wolf and his colleagues found that most of the rhetoric about “water wars” was merely anecdotal, so they systematically documented how countries sharing river basins actually interact in their Basins at Risk project. The findings were surprising and counterintuitive: “Regularly we see that at any scale, two-thirds of the time we do anything over water, it is cooperative,” and actual violent conflict is extremely rare, said Wolf.

    Additionally, the regions where they expected to see the most conflict – such as arid areas – were surprisingly the most cooperative. “Aridity leads to institutions to help manage aridity,” Wolf said. “You don’t need cooperation in a humid climate.”


    “It’s not just about change in a basin, it’s about the relationship between change and the institutions that are developed to mitigate the impacts of change,” said Wolf. “The likelihood of conflict goes up when the rate of change in a basin exceeds the institutional capacity to absorb the change.”

    Expanding the Database for Risk Assessment

    Oregon State University’s Transboundary Freshwater Dispute Database (TFDD) tracks tabular and spatial information on more than 680 freshwater treaties along 276 transboundary river basins, said Jim Duncan. The team expanded the database to include recent findings on variability, as well as the impacts of climate change on the future variability of those basins. “We have a lot more information that we are able to work with now,” Duncan said.

    Analyzing the institutional vulnerability of treaties along with hydrological hazards, they found the risk of tension concentrated in African basins: The Niger, Congo, and Lake Chad basins “popped out,” said Duncan. When predicting future challenges, they found that basins in other areas, such as Southeastern Asia and Central Europe, would also be at risk.


    Duncan and his colleagues were able to identify very nuanced deficiencies in institutional resilience. “Over half of the treaties that have ever been signed deal with variability only in terms of flood control, and we’re only seeing about 15 percent that deal with dry season control,” said Duncan. “It’s not the actual variability, but the magnitude of departure from what they’re experiencing now that is going to be really critical.”

    Beyond Scarcity

    “Generally speaking, it’s not really the water so much that people are willing to fight over, but it’s the issues associated with water that cause people to have disagreements,” said Matt Zentner. Water issues are not high on the national security agendas of most governments; they only link water to national security when it actively affects other sectors of society, such as economic growth, food availability, and electric power, he said. Agricultural production – the world’s largest consumer of water – will be a major concern for governments in the future, he said, especially in developing countries economically dependent on farming.

    Some experts think that current international treaties are not enough, said Zentner. Peter Gleick of the Pacific Institute has said that “the existing agreements and international principles for sharing water will not adequately handle the strain of future pressures, particularly those caused by climate change.”

    How transboundary water treaties fare as the climate and consumption rates change is not as simple as measuring flow; the strength of governing institutions, the parties involved, and other variables all play major roles as well, said Zentner. “When you have flexibility built within [a treaty], it allows it to be a living, breathing, and important part of solving those [water] problems.”

  • Conflict Minerals in the DRC: Still Fighting Over the Dodd-Frank Act, One Year Later

    One year after the Dodd-Frank Act passed Congress with a provision that was aimed at preventing the sourcing of “conflict minerals” by SEC-registered companies, backlash seems to be growing over the impact of the measure, particularly on artisanal miners in the Democratic Republic of the Congo (DRC).

  • Environmental Cooperation for Peacebuilding in Sierra Leone

    ›
    From the Wilson Center  //  August 10, 2011  //  By Jimmy Brousseau
    Sierra Leone’s decade-long civil war led to a complete collapse of environmental management in the country, according to Oli Brown, an environmental affairs officer with the UN Environment Programme (UNEP). Speaking at the Wilson Center last month, Brown highlighted the country’s current environmental conditions and how they have evolved since the war ended in 2002, while also outlining UNEP’s support for rebuilding the country’s natural resource governance.

    Despite its wealth of natural resources, Sierra Leone is plagued by high unemployment, a massive gap between the poor and wealthy, and extreme poverty – 70 percent of the population lives on $1.00 a day. The country is still “very fragile,” said Brown; the poor distribution of resources is partly responsible for the current problems facing the country.

    Sierra Leone’s environmental future and prospects for improving its natural resource governance depend on the answers to three key questions, said Brown:
    • How can the countries bountiful natural resources be shared more equitably?
    • How can the countries natural resources improve local livelihoods and provide jobs?
    • How can the war’s legacies be properly addressed while minimizing their negative impact?
    The first 5 to 10 years after a civil war are a critical time for peacebuilding efforts, Brown emphasized. Natural resources can help in this peace building process, but countries must recognize the value of their natural resources, and establish policies that are sustainable – environmentally, economically, and socially.

    Potential in Abundance: Agriculture, Minerals, Fisheries, and Tourism

    Today, agriculture – including rice, palm oil, and sugar cane – accounts for 50 percent of Sierra Leone’s GDP, but current production methods are extremely inefficient, said Brown. Farmers use slash-and-burn clearing techniques to grow crops with zero consideration for the environmental effects, a practice which has led to a high level of deforestation. Only four percent of the country’s original forest cover remains, he said.

    As part of its plan, Sierra Leone’s government is actively seeking large-scale investment in agricultural products for export. However, access to land development is complicated by the fact that more than 100 different chiefs control land and leasing rights around the country.

    Additionally, some fear that companies investing in Sierra Leone may be exploiting the situation to achieve maximum profit without providing local development benefits, such as employment.

    Water is also crucial to agriculture development, but Sierra Leone’s government does not know how much they have, said Brown, so they cannot properly plan for addressing the needs of their people. Reforming the sector is critical, as palm oil and sugar cane in particular have great potential for increasing the country’s GDP.

    Sierra Leone also has an abundant supply of minerals: Diamonds, iron, rutile, gold, and oil currently account for about 20 percent of GDP and approximately 250,000 jobs, said Brown.

    The planned Tonkolili iron mine will be the largest of its type built over the past 20 years anywhere in the world. If successful, the mine could double Sierra Leone’s GDP, he said. But the government must monitor these mining operations to ensure that the environmental damage does not undermine the economic benefits, said Brown. For example, rutile mining without proper safety precautions has produced acid lakes, he said, some of which have been measure with a PH level of 3.7 or greater.

    While fishing operations in Sierra Leone make up only 10 percent of GDP, fish provide 80 percent of the animal protein consumed in the country’s households. However, lack of regulation and enforcement has left the door open for rampant illegal and unregulated fishing, said Brown, which has depleted local fish stocks and reduced the size of fish that are caught threatening the country’s food security.

    On a more positive note, environmental tourism could be a potential source of sustainable revenue. The large chimpanzee population and the national parks could be strong tourist draws. However, the country must overcome its “blood diamonds” stigma in order to take advantage of its potential.

    UNEP is seeking to help Sierra Leone’s government develop its environmental regulations and planning, said Brown, such as ways to measure and regulate water usage. The regulation of agriculture, minerals, fisheries, and tourism industries will be vital steps toward helping Sierra Leone build a sustainable economy and a sustainable peace.

  • PRB’s Population Data Sheet 2011: The Demographic Divide

    ›
    August 9, 2011  //  By Kellie Furr
    “Today, most population growth is concentrated in the world’s poorest countries – and within the poorest regions of those countries,” write the authors of the 2011 Population Data Sheet, an analysis tool published annually by the Population Reference Bureau (PRB). The population projections between poor and rich countries are “stark and very sad,” said Carl Haub Haub, senior demographer at PRB, at the July 28 web-based launch of the Data Sheet: “We call it the demographic divide. It shows the vast difference that has developed between the rich and poor countries of the world.”

    The Population Data Sheet offers insight on global population trends using detailed statistical information along 18 demographic, population, health, and environment indicators for more than 200 countries and regions. The data sheet is based on the latest projections of the UN Population Division. Carl Haub and James Gribble of PRB discussed the long-term implications of the data sheet’s projections during web-based launch that included open questions.

    Conflicting Trends

    “Even though the world population growth rate has slowed from 2.1 percent per year in the late 1960s to 1.2 percent today, the size of the world’s population has continued to increase – from 5 billion in 1987, to 6 billion in 1999, and to 7 billion in 2011,” write the authors in PRB’s July Population Bulletin, “The World at 7 Billion.” To put those population totals into perspective, it took from the inception of human existence until the year 1800 – a total of approximately 50,000 years – to reach the first billion.

    Fortunately, the recent (relative) decline in global growth rate has already curbed what could have been a considerable surge in the world’s population: “If the late 1960s population growth rate of 2.1 percent – the highest in history – had held steady, world population would have grown by 117 million annually, and today’s population would have been 8.6 billion,” said PRB President Wendy Baldwin in a press release. However, the world’s population still grows significantly at 77 million people annually, according to the UN, and we’re slated to reach 8 billion in just another 12 years. How can this dichotomy of large population totals in the face of lowered fertility be explained?

    The Phases of Demographic Transition

    “To understand global, we actually have to think local,” said PRB in their film short, “7 Billion and Counting,” released alongside the data sheet. Individual countries go through demographic transitions at different times, and the disparity in where countries are along in their progression varies greatly.

    A demographic transition essentially hinges on two trends: the decline of birth and death rates over time. These trends do not necessarily change simultaneously however, resulting in most cases, first, a natural increase (when mortality rates decline but birth rates remain high) followed by a natural decrease in population (when birth rates also decline). Though the timing and magnitude of these trends differ from place to place, there are broad similarities across countries which have been conceptualized as phases by demographers, such as Carl Haub and James Gribble.

    Phase one is characterized by high birth rates and fluctuating death rates, found in countries such as Niger, Afghanistan, and Uganda; typically only death rates decline in this phase. Phase two, encompassing mostly lower-middle income countries such as Guatemala, Ghana, and Iraq, is marked by a continued decline in death rates but only slightly lower birth rates. The potential for large population growth exists in these countries, as they still possess a large youth population.

    Countries in phase three have yet lower birth and death rates and overall total fertility rates close to the widely-accepted replacement level of 2.1 children per woman; these countries are home to approximately 38 percent of the world’s population and include India, Malaysia, and South Africa. Phase three countries often still possess a disproportionately large working age population as an echo of their previous growth, which allows them to take advantage of the “demographic dividend.”

    Finally, phase four countries have the lowest birth and death rates, with some even seeing negative growth as total fertility rate falls at or below the natural replacement rate; countries in this phase include most of Europe and other developed countries, such as Japan and the United States (though relatively high levels of immigration keeps overall growth higher).

    The data sheet shows that most developing countries still remain in the earlier phases of demographic transition, especially those in sub-Saharan Africa and the Middle East. Relatively recent public health improvements in these countries have decreased death rates at a rapid rate, and though total fertility rates (TFR) have declined as well, they have not kept the same pace: “This lag between the drop in death rates and the drop in birth rates produced unprecedented levels of population growth,” wrote Haub and Gribble in the Population Bulletin.

    A Tale of Two Worlds

    The data sheet authors observe that poverty is strongly associated with countries which are stalled in their progression through the demographic transition:
    Poverty has emerged as a serious global issue, particularly because the most rapid population growth is occurring in the world’s poorest countries and, within many countries, in the poorest states and provinces…Relatively high population growth rates make it more difficult to lift large numbers of people out of poverty.
    In her primer video on demographic security for ECSP, demographer Elizabeth Leahy Madsen said, “we are in an era of unprecedented demographic divergence,” and characterized the phenomenon of population trends moving simultaneously in different directions as “rapid” and “unprecedented.”

    Haub used Italy and the Democratic Republic of Congo (DRC) as an example to illustrate the divide. Although both countries currently sit at around 60 million people each, Italy is only projected to grow by 2 million through 2050, while the DRC is projected to reach a staggering 149 million people. Italy has a gross national income per capita of about $35,000, whereas DRC has only $180 per capita, according to the World Bank.

    This observation has been corroborated by other demographers: “In 1950, 68 percent of the world’s population resided in developing regions. Today that’s up to 82 percent. But in the year 2050, it’s projected to be 86 percent,” said demographer David Bloom on NPR’s global health blog, Shots.

    Demography ≠ Destiny

    A poor country is not necessarily tethered to its projections, which are based on assumptions, said the authors, “but when, how, and whether [the demographic transition] actually happens cannot be known.”

    Low development indicators do not always dictate that a country will lag in a demographic transition. “Government commitment to a policy to lower [birth rates] has succeeded quite well in countries with a low level of development,” said Haub in a 2008 PRB discussion on the demographic divide. Bangladesh and Iran are two examples of countries that significantly affected their demographic trajectories in the 20th century with targeted programs.

    Proactivity certainly plays a role, as the PRB “7 Billion and Counting” video puts it (see above): “Understanding how and why the world’s population is growing will help nations better plan for the future…and for future generations.”
