Family Planning and Results-Based Financing Initiatives
›“Family planning means healthier moms and kids – and it’s good for development too,” said Lindsay Morgan, a senior health analyst at Broad Branch Associates, a healthcare advocacy group. But any number of hurdles can keep women from accessing family planning services. Morgan spoke at a May 21 discussion about results-based financing (RBF) programs, which aim to address hurdles on both the supply and demand sides of the equation in developing countries by incentivizing the provision of a variety of quality services while removing barriers to access for women in need of those services.
Removing Barriers to Providing and Using Family Planning Services
Incentives in RBF programs can come in a variety of forms – like subsidies or fees paid to clinics or vouchers sold to women, said Morgan. In Burundi, for example, under a pilot program rolled out across three provinces in 2006, health facilities receive payments for each patient that uses a modern method of contraception. In 2009, the government and international partners began scaling up the program to a nationwide level. In addition to expanding the program’s geographic reach, the scale-up incorporated new payment criteria to better incentivize quality of care (as opposed to just quantity) and longer-lasting methods of contraception.
Since the RBF pilot began, maternal and child health indicators have improved. The number of children being fully immunized is up, as is contraceptive prevalence, said Morgan. Additionally, those immediate results can lead to a slew of additional benefits down the line. For instance, improving modern contraceptive prevalence is one of the most cost-effective interventions available for reducing maternal death, she said.
In nearby Kenya, the health ministry leads a voucher system across four districts and two Nairobi slums to help some of the country’s poorest women afford maternal healthcare, family planning, and gender-based violence services.
The program is “written into large policy documents [and] strategic pieces,” including Vision 2030, a long-term government-wide strategy document “unveiled in 2008 as a way to reach middle-income country status by 2030,” said Ben Bellows, a reproductive health associate at Population Council Kenya. The government’s emphasis on the voucher program as more than just a health initiative is an acknowledgment of the downstream impact that improved maternal and reproductive health can have on the country’s development, he said.
“An Equity Gap in Family Planning”
However, the fact that the voucher program is needed at all is evidence of “an equity gap in family planning,” Bellows said. Access to family planning services can be significantly skewed depending on a woman’s income level, he said, pointing to a recent article in The Lancet assessing health inequalities in 12 different maternal and child health services across 54 priority Millennium Development Goal countries.
The equity gap reflects “an interesting problem with development,” said Bellows: Though low-income countries are converging with higher income countries, in terms of economic growth rates and income levels “the benefits of growth aren’t being evenly distributed.” The Africa Progress Panel’s annual report, released last month, echoes that point, he said.
“Governments are failing to convert the rising tide of wealth into opportunities for their most marginalized citizens,” the report concludes, and “unequal access to health, education, water and sanitation is reinforcing wider inequalities.”
Kenya’s voucher system is designed to help shrink that gap. Among the poorest of the poor – those benefitting from the system – inequalities are dropping, even if on a broader scale, inequity still exists between poor and wealthy Kenyans. “We’re seeing lower inequalities of service in areas exposed to the voucher,” said Bellows.
“RBF supports progress on a path towards universal health coverage,” said Beverly Johnston, the senior policy advisor at USAID’s Office of Population and Reproductive Health. And within the context of family planning “the whole idea is to level the playing field” so that all contraceptive methods are equally readily available to the women seeking them.
“A Catalyst for Change” in Family Planning
In addition to addressing equal access concerns, RBF programs can serve as “a catalyst for change…to stimulate quality of care and quality of family planning counseling in particular,” said Johnston.
A commonly cited hurdle to better family planning access is social norms that support large family sizes or otherwise limit a woman’s ability to space or limit her pregnancies. Given community health workers’ unique roles within their communities – “often on the front lines…where many of these social taboos and barriers exist,” as Morgan described – simply strengthening their training, and in turn improving the quality of care that women receive, can help counter norms that might otherwise prohibit access to family planning.
As more women receive higher quality care, norms dissipate even further, said Morgan. “There is evidence that [quality of care] is strongly associated with a woman’s decision to choose a method to use, to continue to use it, and to recommend it to others.”
“Rights Are Tantamount”
One trap RBF programs need to be aware of is over-incentivizing expansion of coverage to the detriment of quality or individual women’s concerns about what makes sense for them, said Johnston.
“Rights are tantamount,” she said. In order to ensure that rights are upheld, programs must reflect and be sensitive to local histories and local needs – particularly given the fact that some countries have had “a history of coercive programs and policies.”
Ultimately, “we really look at RBF as just one tool,” said Johnston. “RBF is not for every place and every context,” and neither is family planning’s place in RBF programming.
As one tool of many, RBF programs are gaining prominence as a way to meet MDGs related to maternal and child health. Bellows sees RBF’s importance lasting long past that 2015 deadline, though.
“The high inequity that we witness across many low-income countries, and the ability of targeted mechanisms [like Kenya’s voucher program] to address that, suggest that this may be a kind of generalized solution,” he said. “Obviously it will be context specific in the way in which it is rolled out, but the strategy of incentivizing clients and providers suggests that there’s some sort of globalized solution that could be considered for this widespread challenge.”

Republic of Congo Demographic and Health Survey Shows High Maternal Health, But No Fertility Decline
›June 5, 2012 // By Wilson Center StaffThe original version of this article, by Carl Haub, appeared on the Population Reference Bureau’s Behind the Numbers blog.
The Congo (Brazzaville) 2011-2012 Demographic and Health Survey (DHS) is the second DHS taken in the country and the preliminary report has just been released. The survey interviewed 10,819 women ages 15-49 and 5,145 men ages 15-59 from September 2011 to February 2012. A major finding of the survey was that fertility has not declined in the country since the previous DHS in 2005. The total fertility rate (TFR) report in the recent DHS for the three year period before the survey was 5.1 children per woman, 4.5 in urban areas, and 6.5 in rural areas. This appears to represent an increase in the TFR since 2005 but the survey report cautions that there is likely to have been some understatement of the actual level of childbearing in the 2005 survey, particularly among women ages 25-29.
Rural women accounted for two-thirds of those interviewed in the most recent survey. The rather high TFR is reflected in the desire for large families. Among women with five living children, only 37.3 percent said they did not wish to have additional children. An additional 9.8 percent of that group said they were incapable of conceiving, however.
In the survey, 44.7 percent of currently married or in-union women said that they were using some form of family planning and 20 percent were using a modern method. The most common type of modern method was the male condom at 12.3 percent, a rather unusual pattern of contraceptive use in Africa. That was followed by the pill at 2.9 percent and injectables at 2.8 percent. This continues the often-observed preference in sub-Saharan Africa for methods to space births, not necessarily to limit them. The use of modern contraception was 24.6 percent in urban areas and 11.7 percent in rural areas. Modern contraception rose since the 2005 DHS when it was reported at 12.7 percent and the condom was also the most frequently used method at that time. The prevalence of HIV was reported in the 2009 AIDS Indicator Survey at 4.1 percent for women ages 15-49 and 2.1 percent of men of the same age group.

Bringing Environment and Climate to the 2012 Population Association of America Annual Meeting
›June 5, 2012 // By Sandeep BathalaOver 2,100 participants attended the 2012 Population Association of America (PAA) annual meeting in San Francisco this May. PAA was established in 1930 to research issues related to human population. This year, for the first time, the meeting featured a notable contingent of demographers, sociologists, and public health professionals working on environmental connections.
I followed as many of the environment-population discussions on newly published or prospective research papers as possible (about 20 in total). I found four papers particularly noteworthy for the connections made to women, family planning, and climate change adaptation.
Samuel Codjoe of the University of Ghana spoke about adaptation to climate extremes in the Afram Plains during one of the population, health, and environment (PHE) panels organized by Population Action International. Although developed nations are historically the major contributors of greenhouse gases due to comparatively high levels of consumptions, developing countries are the most vulnerable to the consequences of climate change – in part because of continued population growth. As a result, adaptation strategies in countries like Ghana are particularly important; and given women’s often-outsized role in water and natural resource issues, a focus on gender-specific adaptation even more so.
Codjoe presented an analysis of preferred adaptation strategies to flood and drought, broken down by gender and three common occupations – farming, fishing, and charcoal production). He said he hopes his assessment – part of a collaborative research effort with Lucy K.A. Adzoyi-Atidoh of Lincoln University – will aid in the selection and implementation of successful adaptation options for communities and households in the future.
“Understanding differences in the priorities that women place on adaptation may prove to be important in the effectiveness of climate change adaptation – and the sustainability of communities,” he said.
David López-Carr of the University of California, Santa Barbara, speaking on behalf of a group of researchers with World Wildlife Fund, teased out the gender dynamic further when he presented on ways to help the conservation sector determine next steps for existing PHE projects. Practitioners from seven of the eight PHE projects currently implemented by conservation organizations (defined by having been involved for at least three years in bringing family planning to local communities) recently said the links to women’s empowerment were among the most important aspects of successful projects.
López-Carr therefore emphasized the need for additional research on how PHE projects can support and empower women, both economically and socially. He also noted, like Codjoe, the potential impact women often have on the management of their community’s natural resources, saying this was another area where research on the empowering effect of PHE programs can provide further backing for integrated programs.
Karen Hardee of Futures Group spoke about how the experiences of integrated PHE projects, despite most not being designed to respond to climate change specifically, have lessons to offer climate change efforts. Her work was done in partnership with the Population Reference Bureau, Population Action International, and U.S. Agency for International Development. She concluded that community-based adaptation approaches should consider population dynamics in vulnerability assessments. Meeting unmet need for family planning, she said, can assist communities adapting to climate change by building resilience. And as result, “PHE approaches should be able to qualify for funding under community-based adaptation programs.”
Shah Md. Atiqul Haq of the City University of Hong Kong presented research he conducted in Bangladesh that found that women tended to feel that a large family size was not advantageous during floods. This, he said, was indicative of their increased understanding of vulnerability and an endorsement of providing knowledge and access to family planning services as part of climate change adaptation strategies.
The inclusion of more environment, and particularly PHE, related presentations at this year’s conference was good to see – perhaps a sign that demography is becoming a more complex and comprehensive field, with a focus more on population structure and its interactions with other issues, rather than a singular fascination with growth.
In particular, panelists showed that the nexus between demography, gender equity, and climate change continues to grow in importance, both in the research and practitioner communities.

USAID’s New Global Health Framework and Delivering Equity in Health Interventions
›USAID’s new Global Health Strategic Framework, Better Health for Development, lays out the agency’s major health priorities for the next five years. “Core global health priorities” include reducing maternal mortality, ensuring child survival and nutrition, fostering an “AIDS free generation,” and fighting infectious diseases. Family planning and reproductive health is listed as a key area for bilateral engagement. In particular, the strategy hopes to continue to “graduate” countries from the agency’s family planning program, which since the 1980s has transitioned 21 countries into local ownership of family planning support. The strategy also takes stock of the shifting global health environment, noting the rise of the “BRICS” countries as new donors and the need to strengthen public health systems in developing countries. “Already, private payments account for 50-80 percent of total health spending in Africa and Asia, leading to system inefficiencies, inequitable access, and health costs that prove catastrophic to individuals and families,” the report reads. In order to achieve its priorities within this context, the document sets out a number of strategies, including a focus on program sustainability, the empowerment of women, and integrated approaches to development. Health, it says, “cannot be isolated from other development challenges.”Speaking of health interventions, a team of researchers led by Aluisio Barros of the Federal University of Pelotas, Brazil, recently compared coverage data from more than 50 countries against an index of household wealth to estimate the most and least equitable interventions. The study, “Equity in Maternal, Newborn, and Child Health Interventions in Countdown to 2015: A Retrospective Review of Survey Data From 54 Countries,” published in The Lancet, found that “interventions with similar levels of overall coverage often have very different degrees of inequality.” According to the data, “the most inequitable indicator was skilled birth attendant, followed by four or more antenatal care visits, whereas the most equitable was early initiation of breastfeeding.” For example, though the average for attendance by a skilled birth attendant was 53.6 percent across the entire sample, the wealthiest fifth had an 84.4 percent coverage rate and the poorest stood at 32.3 percent. “Interventions that are usually delivered in fixed health facilities…tend to be the most inequitably distributed,” write the authors, with geographical access, financial barriers, and discrimination appearing as likely obstacles for the poor. The authors conclude that, although “concern about inequalities in maternal and child health in poor countries was conspicuously absent from the global agenda in the past,” the availability of new, intervention-specific data provides a means of targeting equity issues in health delivery more successfully. -
Comparing Urban Governance and Citizen Rights in China and India
›Today, according to Xuefei Ren, 129 cities in China and 45 in India have populations of over a million people. Such large-scale urbanization has created major governance challenges. Speaking at a May 23 Asia Program event co-sponsored with the Kissinger Institute on China, United States Studies, and the Comparative Urban Studies Project, Ren, a Wilson Center Fellow, examined two case studies of urbanization-driven governance in China and India and their effect on citizen rights.
Her first case study involved housing demolitions and urban re-development in Shanghai and Mumbai. In Shanghai, nearly a million households were relocated between 1995 and 2008 to make way for hotels, airports, and luxury apartments. City regulations in 1991 and 2001 legalized forced demolitions, and no prior consent from residents was needed.
However, Ren noted that displaced residents “are not quite powerless.” She highlighted the case of a woman who sued the city government after being relocated and was eventually granted the compensation she had requested. In 2003, China’s central government ordered a freeze on large-scale demolitions. Several years later, it passed a “landmark” property rights law.
Meanwhile, in Mumbai, local officials in the early 2000s had their own re-development plans. The Indian city is rife with overcrowded, low-income housing; slums are populated by seven million citizens (40 percent of the city’s total population), and comprise up to 10 percent of Mumbai’s total land area.
In 2004, aware that most of the slums were located in desirable areas – near airports or in central business districts – city planners recognized a major development opportunity. Over the next two years, officials launched a demolition campaign that left 400,000 people homeless. According to Ren, certain categories of residents were theoretically entitled to compensation, but with “legal protections carrying little weight,” most of them received nothing.
Yet, as in Shanghai, Mumbai’s city dwellers successfully fought back. Housing activists staged acts of “direct agitation,” including a series of street protests and road blockages. Such tactics, said Ren, were “disruptive but effective.” The Mumbai courts sided against the activists in 2006, but India’s Supreme Court later issued a ruling in their favor.
Fighting Land Acquisitions: A Comparison
Ren’s second case study compared land acquisition efforts outside the slums.
Last year, residents in Wukan, a village along China’s southeast coast in the province of Guangdong, launched a protest movement against land seizures. They alleged that government officials had sold their land to developers and failed to provide residents with appropriate compensation. The protestors made two demands: the return of their land and the holding of local elections.
Notably, Ren said, protestors in Wukan affirmed their support for the Communist Party, and never framed their movement as an anti-government effort. In March 2012, local elections were in fact held, with two leaders of the protest movement voted into office (one as village chief, the other as his deputy).
Ren also discussed an attempt by India’s Tata Motors corporation to acquire land in Singur, a village about 100 miles from Calcutta in the state of West Bengal. The company wanted to use this land to construct a factory for the Nano, a small, cheap car marketed to India’s urban middle class. In 2005, the West Bengal government, which had been controlled by the Communist Party of India-Marxist (CPI-M) for nearly 30 years, actively wooed the firm. State authorities “went overboard” in offering Tata Motors subsidies and highly fertile land, said Ren. Small landowners were obliged to surrender their plots at low prices, and in 2006 the corporation formally took over the land (nearly 1,000 acres altogether), despite heavy opposition from peasants.
However, violent protests continued and after several months, Tata Motors was forced to pull out of West Bengal. Then, in a state election in May 2011, the Trinomool Congress Party, led by the populist leader Mamata Banerjee, swept the CPI-M from power. Banerjee had run her campaign on a promise to restore the land to Singur’s farmers.
Just weeks after the new government assumed power, West Bengal passed a law that would allow for about 400 acres from the Tata Motors project to be returned to farmers who had refused government compensation for their land.
Ren acknowledged that in both countries, citizenship rights are not enjoyed by all and tend to be unevenly distributed across social groups. Still, she concluded, Chinese and Indian cities “have become strategic sites for reassembling citizen rights.” By asserting their land and housing rights, city denizens “are becoming active citizens.”

Environment, Natural Resource Guidelines for Peacekeepers Moves UN Closer to ‘Greening the Blue Helmets’
›May 30, 2012 // By Stuart KentUN peacekeepers not only operate in conflicts where land and natural resources are a component of the fighting but their own bases and operations can also impact the local environment. As well as documenting practical steps to minimize the footprint of field missions, a new report from the United Nations Environment Program (UNEP) reviews the relationship between natural resources and conflict and what it means for peacekeeping.
While there’s been talk about “greening” UN peacekeeping for years, the details about the economic, environmental, and mission benefits contained in Greening the Blue Helmets: Environment, Natural Resources and UN Peacekeeping Operations suggest that this talk is getting closer to reality.
As of December 2011, the UN’s Department of Peacekeeping Operations was responsible for 121,591 personnel, 17,000 vehicles, and 257 aircraft across 16 different operations worldwide. These forces account for more than half of the entire UN system’s carbon emissions and can significantly strain the resources of fragile host communities, according to the report.
Building on the 2009 Environmental Policy for UN Field Missions, the UNEP report provides a dozen best practice examples from ongoing missions.
Field cases serve as evidence of how increasing water and energy efficiency, safely discarding solid and hazardous wastes, protecting cultural and historical sites, and ensuring a limited footprint after the closing down of camps, can save environmental and financial resources. These measures, the report claims, also reduce the risk of tension with host communities, such as occurred in Haiti when an outbreak of Cholera was traced to unsanitary water management practices at a UN camp.
Technologies recommended include better waste management systems, improved water systems, energy efficient buildings, and green energy capacities. However, some improvements can be made by simply encouraging behavioral changes; the UN mission in Timor-Leste reduced energy consumption by 15 percent over 12 months using a “CarLog” system to encourage fuel efficiency. With a 2009 global fuel bill of $638 million, even a 15 percent margin relates to a significant figure (much like the logic behind similar efficiency efforts within the U.S. military).
However, uncertain mission lengths are a major barrier to the adoption of more efficient technologies. Despite UN operations lasting an average of seven years and evidence indicating that capital investments could be recovered within one to five years in some cases, year-to-year mandates complicate long-term planning.
Natural Resource Nexus
Conceptually, the nexus of natural resources, conflict, and peacebuilding must be a central concern of peacekeeping operations, asserts the report.
In Africa alone, 13 operations have been conducted in response to conflicts associated with natural resources, at a cost of around $32 billion. Exploitation of natural resources such as diamonds, timber, and oil has financed and fueled conflicts in Sierra Leone, the Democratic Republic of the Congo, and Liberia. Communal tensions over access to scarce land and water resources are also considered an exacerbating influence on conflict dynamics in much of Sudan and now South Sudan, according to the report.
Addressing this nexus can also provide opportunities to reduce and redress conflict. In Darfur, firewood collection is a dangerous task for women and girls. By making “firewood patrols” a regular feature of the UN forces’ protection, the prevalence of sexual violence has been limited.
The UN Assistance Mission in Afghanistan is cited in the report for its efforts to hire ex-combatant and vulnerable populations to aid in the reforestation of extensively degraded pistachio woodlands from 2003 to 2009.
“Natural resources can provide opportunities for emergency employment and…sustainable livelihoods for former combatants,” write the authors.
Countries recovering from episodes of violence tend to have a low capacity to effectively and equitably manage a natural resource base that itself may have been degraded by conflict. Recent attention, however, is being paid to the peacebuilding potential of managing shared resources.
According to the report, “while only 54 percent of peace agreements reached between 1989 and 2004 contained provisions on natural resources, all of the major agreements concluded between 2005 and 2010 included such provisions.” This includes the renovation of land tenure systems, management of valuable extractive industries, and reallocation of resource rents.
Preventing Predatory Extraction
As peace begins to take hold, “access to land may be a key determining factor affecting the successful reintegration of a former combatant into a community.”
According to interview data from Northern Uganda, 93 percent of male LRA ex-combatants were unable to access land after demobilization. Often due to the death of an elder relative, sale of land by a family member, or land grabs by other members of the community.
While shared resources can build trust between communities, spoiler groups that use aggressive means to secure resource rents in the aftermath of conflict can endanger a fragile peace. The report identifies a role here for peacekeeping forces – and in particular for their civilian contingent – to identify these potential risks and opportunities for action.
In particular, the report recommends a higher level of clarity about the relationship between peacekeeping forces and so called “expert panels” – groups of civilian specialists called upon by the Security Council to provide advice on an official basis about natural resources in the aftermath of conflict.
The UN mission in the Democratic Republic of Congo, for instance, was given a direct mandate in 2008 to work with the DRC expert panel and to “use its monitoring and inspection capacities to curtail the provision of support to illegal armed groups derived from illicit trade in natural resources.”
UNEP Program Officer Matti Lehtonen, in an email interview, called the panels a “tremendous asset that is not yet used up to its full potential.” However, he noted, “expert panels and peacekeeping missions are different tools with different objectives so there is also a need to maintain a degree of independence.”
The report identifies a set of key recommendations for the UN moving forward:- Ensure that pre-deployment and in-mission training includes instruction on environment and natural resource management
- Aid and encourage disarmament, demobilization, and reintegration programs to look closely at emergency employment and sustainable livelihoods related to natural resources and the environment
- Support and encourage civil affairs personnel to seek ways to capitalize on peacebuilding opportunities around natural resources and the environment
- Systematically inform the Security Council of linkages between natural resources and conflict in states where the Council may be considering action
- Where natural resources have fueled or financed conflict, provide peacekeepers with a more systemic mandate to act on these issues
- Effectively implement best practices identified in the 2009 environmental policy

Full Extent of Africa’s Groundwater Resources Visualized for the First Time
›“In Africa, groundwater is the major source of drinking water and its use for irrigation is forecast to increase substantially to combat growing food insecurity,” yet, a lack of quantitative data has meant that “groundwater storage is consequently omitted from assessments of freshwater availability,” according Alan Macdonald, Helen Bonsor, and Brighid Dochartaigh of the British Geological Survey, and Richard Taylor of University College London, writing in Environmental Research Letters.
The authors hope to remedy this with new research presented in “Quantitative Maps of Groundwater Resources in Africa.” They used estimates compiled from geologic data and 283 aquifer summaries from 152 different publications to quantitatively visualize, for the first time, the full extent of Africa’s groundwater resources.
Tapping a Hidden Resource
The study estimates the scale of the continent’s groundwater resources at around 0.66 million km3. This volume, the authors explain, is “more than 100 times the annual renewable freshwater resources, and 20 times the freshwater stored in African lakes.”
Tapping into this massive resource is not always straightforward, however. The largest aquifers, and those most able to support high yielding bores, are concentrated in the arid regions of North Africa. The depth of these aquifers and their distance from major populations creates substantial economic challenges for extraction.
The geographic distribution of aquifers across sub-Saharan Africa is also quite variable, and local geology can determine not just the availability and accessibility of water but also its quality. For instance, geologic specificities can result in elevated levels of arsenic and other undesirable chemicals. Furthermore, “contamination…is common in urban areas from widespread and dispersed faecal effluent from on-site sanitation and leaking sewers.”
Tempering Expectations
Throughout Africa, “groundwater provides an important buffer to climate variability and change,” say the authors. But these buffers are not a singular solution to the threat of future water scarcity.
As the analysis shows, most aquifers, especially south of the Sahara, are unlikely to sustain boreholes of a higher capacity than that required by community-level hand pumps (one liter per second of flow at minimum). Yet, commercial irrigations schemes and urban towns typically demand boreholes greater than five liters per second, according to the study.
So, groundwater extraction may help communities and some small-scale farmers maintain access to water, particularly because many aquifers are found to possess the storage capacity required “to sustain abstraction through inter-annual variations in recharge,” however, “strategies for increasing irrigation or supplying water to rapidly urbanizing cities that are predicted on the widespread drilling of high yielding boreholes are likely to be unsuccessful.” Especially, the authors assert, where drilling precedes detailed local scale mapping of the available resources.
