‘Marketplace’ and ‘NewsHour’ Highlight Population, Health, and Environment Program in the Philippines
›The Danajon reef is the only double barrier reef in the Philippines, “one of the richest marine biodiversity hot spots in the world,” and it’s being devastated as the country’s exploding population depends on its waters for their food and livelihoods, reported Sam Eaton in a recent two-part series on population, health, and environment issues in the Philippines broadcast last month for American Public Media’s Marketplace and the PBS NewsHour.
The report is part of joint project called Food for 9 Billion, with Homelands Productions, the Center for Investigative Reporting, APM, and PBS. Previous reports examined food security in East Africa and Egypt.
The Philippines “import more rice than any other country on the planet,” said Eaton. The “highest population growth rates in all of Southeast Asia” as well as dwindling natural resources – nearly 100 million people live in a land area the size of Arizona – have created a cycle of poverty. The first step to breaking that cycle, he said, is improving access to family planning.
Growing Families, Growing Poverty
The Canayong family, living on the edge of a garbage dump in a Manila slum, offers a vivid example of what poverty means in the Philippines. Clarissa Canayong has had 14 children – 4 died from measles and dengue fever, the remaining 10 spend their days alongside Clarissa, sifting through the dump for things they need and things they can sell. At the end of a good day, the family has earned around $7 to survive on. All in all, Clarissa’s “inability to provide enough food, and to pay for her children’s education, all but guarantees she and her family will remain poor,” said Eaton.
The archipelago adds about two million people every year, putting population on track to double in size sometime around 2080. “And that’s only if something is done to close the birth control gap,” said Eaton, as those projections build in an expectation that growth will slow.
“As cities all across the country expand, the displaced often end up migrating to urban slums,” he said. “Population growth among poor Filipinos is twice the national average,” meaning that once a family enters poverty, they end up in a cycle “that’s nearly impossible to break.”
The Difference Family Planning Can Make
If Clarissa had had access to family planning, she told Eaton, she would have wanted to have only two children. In Humayhumay, where residents have access to a community-based family planning distribution program started by PATH Foundation Philippines, Inc., families have that luxury of choice.
Working through local partners, the PATH Foundation identifies and trains community-based vendors to sell contraception – both pills and condoms, said Dr. Joan Castro, who began the program in Humayhumay. The idea is to make buying contraceptives “as easy as buying soft drinks or matches.”
Both Jason Bostero, a farmer and fisherman in Humayhuay, and his wife, Crisna, grew up in large families – so large, in Crisna’s case, that “sometimes, we would only eat once a day because we were so poor. We couldn’t go to school. I did not finish school because there were just so many of us,” she told Eaton.
Now that they have access to contraceptives, a smaller family size means their income is “just right” to feed everyone three times a day. For the community as a whole, smaller family sizes mean that the nearby fish stocks that provide the community with food and income have a chance to replenish themselves in the absence of overfishing.
“In just six years since the program was first established here,” reported Eaton, “family sizes have plummeted from as many as 12 children to a maximum of about 4 today.”
Exception to the Rule
Humayhumay is an exception to the rule in the Philippines. There is no state funding for birth control in the country, and over the past few years, major international donors like USAID and the United Nations have ended their family planning work in the country. More than a quarter of poor Filipinos have no access to any type of family planning service, and more than half of all pregnancies are unintended, said Eaton.
Family planning has long been a contentious issue in the country. Eaton spoke to Congressman Walden Bello, who has spent more than a decade trying to pass legislation to establish universal access to birth control and improve other family planning and reproductive services. The Catholic Church, said Bello, is a powerful (80 percent of Filipinos are Catholic) and consistent opponent. In October 2010, the Church went so far as to threaten President Benigno Aquino with excommunication after he voiced support for access to contraception.
Rather than limit population growth, the Church argues the country should increase food production. But land is limited, rice imports are already the highest in the world, and, “according to the World Bank, every major species of fish here shows signs of severe overfishing,” said Eaton.
Looking Forward and Abroad
Eaton pointed to the Philippines’ neighbors as examples to emulate: “A long history of government-supported family planning has…paved the way for Thailand to become one of the world’s biggest rice exporters” and helped to cut back poverty in the country, said Eaton.
Indonesia too, he pointed out, has largely avoided the population growth-resource depletion-poverty cycle, thanks in part to a state- and faith-backed family planning program. (As Elizabeth Leahy Madsen wrote in a recent New Security Beat post, the decision of Indonesia’s religious leaders to throw their support behind family planning in the 1960s was a key factor in success there.)
Considering the obstacles, the Philippines face an uphill battle before family planning services become similarly universal. But the political tides may already be turning: last April, the President said he would support the reproductive health legislation even if it meant excommunication.
Meanwhile, PATH Foundation’s Castro is hopeful that Humayhumay’s success story will lay the seeds for widespread public support for family planning. “The vision of the project is in this community you see more children educated who are able to become leaders and speak out for themselves in the future and be able to become stewards of their own sexuality and the future environment,” said Castro. “This is the legacy.”

Richard Black: Future Climate-Migration Interactions Will Stress Cities, “Trap” Vulnerable Populations
›“In a 50-year time span, climate change, in particular, is likely to have a quite a strong impact on the drivers of migration,” said Richard Black, professor of human geography at University of Sussex and lead author of Migration and Global Environmental Change: Future Challenges and Opportunities. “But in a way that is different to what has been understood until now.”

UNEP Maps Conflict, Migration, Environmental Vulnerability in the Sahel
›A new set of maps from the United Nations Environment Programme (UNEP) identifies “climate hotspots” – areas vulnerable to instability exacerbated by climate change – in 17 sub-Saharan countries in and bordering the Sahel region. The maps reflect the fact that, more often than not, the impact of climate change on local populations is compounded by changes in migration, conflict, or both. According to Livelihood Security: Climate Change, Migration and Conflict in the Sahel, the UNEP report accompanying the maps, understanding “the exacerbating effect of changes in climate on population dynamics and conflict in the region” will be essential to developing successful adaptation strategies throughout the region.
UNEP’s maps analyze 40 years of data to pinpoint where the region’s most at-risk populations are located based on environmental, population, and conflict trends dating back to 1970. In a single map pinpointing the Sahel’s 19 hotspots, UNEP synthesizes subnational data from four environmental indicators over time – rainfall (from 1970 to 2006), temperature changes (1970 to 2006), drought (1982 to 2009), and flooding (1985 to 2009) – which are then layered on top of population trends (1970 to 2010) and conflict data (1970 to 2005) in order to identify the region’s most insecure areas.
Composite Vulnerability
At first glance, the map can appear hard to decipher; it is flooded with different colors and symbols, each indicating something different about the extent of climate change, migration, and conflict in the region. A Google Earth version of the map (available for download here) makes all this information easier to process by allowing users to select which indicators they want to see mapped out, cutting back on the number of lines, dots, colors, and pie charts the user has to decode.
Given the vast amount of the information being condensed into these maps, the report is a helpful and worthwhile read. For instance, eight hotspots are in places with growing populations and another seven are located in places that have experienced conflict; altogether, 4 of the 19 hotspots have both past conflict and growing populations. The report digs deeper into the confluence of climate, conflict, and migration by discussing case studies that highlight how the three intersect in local communities (at the same time, the report is careful to avoid suggesting that there is a causal relationship between the three issues.). In Niger, Nigeria, and Chad, for example, tensions have been mounting between northern pastoralists and southern farmers as each group has moved further and further afield in search of water and arable land to sustain their livelihoods.
Holes In the Data
While the hotspot maps include a wealth of information, the report makes clear that it is by no means exhaustive. Rising sea levels are, for instance, a major impending threat to coastal populations in the Sahel, but only the downloadable Google Earth map – not the hotspot map in the report or the Google Earth map as presented online – incorporates this factor. Compounded with a skyrocketing population in the coastal areas – the coast between Accra and the Niger delta is expected to be “an urban megalopolis of 50 million people” by 2020, according to the report – an increase in sea levels could have a huge impact on the region’s stability.
The report also readily admits that the datasets for population trends and conflict have shortcomings. Population data is largely based on censuses, which both the report and its data sources (UNEP’s African Population Database and the Gridded Population of the World, version 3) acknowledge can be inconsistent in their accuracy. Additionally, after 2000, population data is based on projections rather than estimates, which, as last year’s update from the UN Population Division showed, have often proven inaccurate, particularly in sub-Saharan Africa.
Regarding conflict, the UNEP report is straightforward in admitting its limits. The report lacks data on small-scale conflict (fewer than 25 battle deaths, following the Uppsala Conflict Data Program’s threshold that separates conflicts from lower-level violence), even as it acknowledges that such conflict is “often the first to occur” when climate change threatens communities’ access to resources and livelihoods.
Ultimately, however, these maps give valuable data on specific locations that are uniquely vulnerable to trends in population, climate, migration, and conflict. They add focus to the conventional wisdom that climate change will impact the region’s stability, and, taken together, the maps and the report provide a valuable resource for scholars and policymakers attempting to craft adaptation policies that take into consideration these complex links.

Jon Barnett: Should Climate Change Be Addressed by the UN Security Council?
›For a small island state like Tuvalu, climate change is an enormous security issue and they have told the UN Security Council as much, said Jon Barnett, professor of resource management and geography at the University of Melbourne, in an interview with ECSP. But, despite debate in 2007 and 2011, the Council has been unable to reach agreement on whether climate change is an international security issue or not.

Jon Barnett: Climate Adaptation Not Just Building Infrastructure, But Expanding Options
›“I think it’s appropriate to think about [climate change] adaptation or investments in adaptation as investments to open up the range of choices available to people to deal with an uncertain future,” said Jon Barnett, associate professor of geography at the University of Melbourne, in an interview with ECSP. “In some circumstances it might be appropriate to build infrastructure and hard options where we’re very certain about the nature of the risk…but in other cases, expanding the range of choices and freedoms and opportunities that people have to deal with climate change in the future is perhaps the better strategy.”

Famine and Food Insecurity in the Horn of Africa: A Man-Made Disaster?
›This year’s drought in the Horn of Africa has been the region’s worst in decades and has exploded into a humanitarian catastrophe affecting millions. In Somalia, where the drought is layered on top of two decades of conflict and an extremely weak state, the impact of the drought has been most damaging. Somalia is the only country in the region where the UN has declared famine zones. And, even though the UN recently upgraded three of Somalia’s six famine areas to “lesser emergencies,” four million Somalis – more than half the country’s population – remain in urgent need of food and general humanitarian aid.
The drought may have been what sparked the current crisis, but other, longer-term factors, like a sustained lack of agricultural development, extreme rural poverty, and changing weather patterns, not to mention Somalia’s lack of functioning government, set the stage.
A Long-Term Crisis in the Making
“Lack of rainfall over several seasons is the most immediate and most visible cause of the current humanitarian crisis in the Horn of Africa,” said Jim Hansen of the Consultative Group on International Agricultural Research (CGIAR) in a brief video produced this summer by the International Research Institute for Climate and Society at Columbia University (watch above). Much of the Horn’s population “depends on rain-fed agriculture and pastoralism for their livelihoods and sustenance,” said Hansen. Already “quite poor and…locked in poverty for quite a long time,” environmental and resource degradation, paired with rapid population growth, have compounded their vulnerability to extreme events, he said.
Throughout the region, resilience to crises like the current drought has been weakened by decades of poor agricultural planning, “driven more by shifts in ideology than any real evidence among some of the key international development organizations,” said Hansen. That poor planning has made communities more dependent on humanitarian aid when poor weather hits, which in turn forces aid groups to redirect resources away from longer-term development and towards short-term disaster relief instead, Hansen said.
While these problems exist across the Horn of Africa, Hansen points out that the crisis has been most damaging in Somalia, which he attributes to the country’s weak governance and to international aid groups’ limited ability to operate in the country.
“Northern Kenya, southern Ethiopia, and Somalia have similar severity of drought, but the humanitarian crisis is much more severe – the loss of livelihood and life is greater in Somalia largely because the government is weaker,” he said.
The Government’s Role
Owen Barder, a senior fellow at the Center for Global Development, draws a more direct line between governance and famine in the Horn. “In Somalia…there’s a complete breakdown of government, and the consequence is the famine that we’re seeing,” said Barder during a Center for Global Development podcast. The country has been without a functioning government since 1991, when civil war broke out. It has since become “the most food-insecure nation in the world” and, as described by Foreign Policy, “the international community’s longest-running failure.”
Barder raised two points about the government’s role in famine. One, that access to information – in this case an early warning system monitoring drought conditions – can minimize the humanitarian impact of any given natural disaster; and two, that a country’s government must be able to translate that information into action in order for it to actually make a difference.
Barder is not alone in emphasizing the state’s role as a driver of the famine. Edward Carr, a AAAS science fellow with USAID, wrote in July, when the UN first declared famine in Somalia, that attributing the famine solely to drought is “a horrible abdication of responsibility for the human causes of this tragedy.”
Charles Kenny, also a senior fellow at the Center for Global Development, went even further on Foreign Policy, arguing that famine, or “mass starvation as an intentional act of governance,” should be categorized as a crime and prosecutable at the International Criminal Court.
Al Shabab and the Months AheadAs of late November, the United Nations estimated that tens of thousands had died in Somalia alone since drought began this spring. Though USAID’s Famine Early Warning Systems Network (FEWSNET) reports that famine has now subsided in three of the six southern regions it initially struck, a quarter of a million Somalis remain at risk of “imminent starvation,” according to the UN.
According to FEWSNET, famine should not reappear in the foreseeable future, assuming aid groups can maintain current distribution levels – a key caveat. Ten days after FEWSNET issued its analysis, however, Al Shabab, the Al Qaeda-linked militant organization that controls much of southern Somalia, banned 16 aid groups, including UNICEF and the World Health Organization, from operating in the areas under its control. UNICEF spokesman Jaya Murthy told the BBC that the move would put “about 160,000 severely malnourished children…at imminent risk of death.”
Fighting in southern Somalia between Al Shabab and Kenyan and Ethiopian forces is adding another layer to the country’s humanitarian crisis. The UN Office of the High Commissioner for Refugees reported that, as of late November, the fighting had become the primary driver of internal displacement, replacing drought and famine as the key drivers during the first three quarters of the year. The UNHCR estimated that, between the drought and the conflict, 1.46 million Somalis have been displaced.
Meanwhile, the rainy season is picking up, and although that’s good news for farmers and pastoralists, it also means that Somalis will be vulnerable to diseases like measles, typhoid, and cholera, which can spread quickly through overcrowded, under-supplied IDP camps. Somalis still living under Al Shabab’s control are prohibited from getting vaccinations, amplifying their vulnerability to disease in the coming months.
These latest developments offer strong evidence that policy decisions can exacerbate the human toll of natural disasters. From Barder’s perspective, that is reason for optimism. “We have the information, we have the capacity to prevent it from happening,” he said.

Twin Challenges: Population and Climate Change in 2050
›With global population reaching 7 billion, a lot of attention has been paid to the question of how to sustainably support so many people, much less the 9 billion expected by 2050, or the 10 billion possible by 2100. Add in the environmental variability projected from climate change and the outlook for supporting bigger and bigger populations gets even more problematic. Two new maps – one by the Population Reference Bureau (PRB), the other by McGill University PhD candidate Jason Samson – show how the world might change over the next 40 years in the face of these twin challenges.
Nine Billion in 2050
PRB’s map, built using their DataFinder tool, shows the world in 2050 in terms individual country growth rates between now and then. Japan, Russia, and countries in Eastern Europe are set to grow more slowly than anywhere else, and some of that group will actually shrink by 10 to 20 percent of their current size. Western, Central, and Eastern Africa will be home to the highest increases. Niger’s 2050 population is expected to be 340 percent its 2011 size – the largest growth of any country.
The map is based on country-level data pulled from a number of sources: the UN Population Division’s latest “World Population Prospects,” the UN Statistics Division’s “Demographic Yearbook 2008,” the U.S. Census Bureau’s International Database, and PRB’s own estimates. It’s unclear what numbers come from which sources, though it is clear that PRB’s 2050 estimates span the UN’s range of medium, high, and constant-fertility variants. In spite of these variations, none of PRB’s estimates come anywhere near the UN Population Division’s low variant estimates.
PRB’s map, echoing its 2011 World Population Data Sheet, shows a world where sub-Saharan Africa will bear the brunt of population growth. The average country in Africa in 2050 is projected to be slightly more than twice its 2011 size; the average European country is expected to barely break even. Africa is home to more countries whose populations are estimated to least double (34) or triple (4) than any other continent. Europe, meanwhile, is home to more countries whose populations will stagnate (8), or even shrink (19), than anywhere else. Interestingly, the Caribbean is a close second in terms of countries whose populations are projected to stay the same (seven to Europe’s eight), and Asia is second to Europe in terms of countries whose populations are projected to shrink (Georgia, Japan, Armenia, South Korea, and Taiwan).
More People, More Climate Change, More Vulnerability
Samson’s map takes on the same time period but projects where people will be most vulnerable to the effects of climate change. Since his map takes into account population growth (measuring where people are most vulnerable, remember), unsurprisingly, Africa, the Middle East, Southeast Asia, and central South America are covered in bright red dots, indicating high vulnerability. Conversely, North America, Europe, and much of Central Asia are in shades of blue.Samson built his index using four environmental predictors – annual mean temperature, mean temperature diurnal range, total annual precipitation, and precipitation seasonality – taken from WorldClim’s 2050 forecasts, and 2005 sub-national population data from Columbia’s Center for International Earth Science Information Network. In spite of the sub-national population data, Samson makes a point to justify his use of supranational climate data in order to best reflect “the scale at which climate conditions vary.” He writes that localized issues like urbanization and coastal flooding “are probably best investigated with targeted regional models rather than by attempting to modify global models to include all factors of potential regional importance.”
Samson’s research shows that, generally, people living in places that are already hot will be more vulnerable to climate change over time, while people in more temperate climates will feel a negligible impact. Though he projects the largest real temperature changes will happen in temperate climates like North America and Europe, the comparatively smaller changes in Africa, the Middle East, Southeast Asia, and central South America are expected to have a greater impact because those regions are already very hot, their natural resources are stressed, and they are expected to bear the brunt of population growth over the next few decades.
These findings reflect a disparity between those responsible for climate change and those bearing the brunt of it, which, although not surprising, “has important implications for climate adaptation and mitigation policies,” said Sampson, discussing the map in a McGill press release.
Sub-National Data “Present a Very Different Picture”
Though they offer a useful approximate glimpse at what the world might look at in 2050, both of these maps fall prey to over-aggregation. By looking at national rather than sub-national data, we miss how nuanced population growth rates can be within a country. Stimson Center Demographer-in-Residence Richard Cincotta wrote in a recent New Security Beat post that “national level comparisons of total fertility rates tend to communicate the false impression of a world with demographically homogeneous states.” Sub-national data, including differences between urban and rural areas and minority-majority fertility rates, “present a very different picture.”
And that difference matters. When it comes to looking at how population interacts with other issues, like the environment, poverty, and conflict, the importance of a sub-national approach becomes evident. In its 2011 data sheet, PRB writes that “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.”Edward Carr, an assistant geography professor at the University of South Carolina currently serving as a AAAS science fellow with USAID, argues that national-level data obscures our ability to understand food insecurity as well. The factors that drive insecurity “tend to be determined locally,” writes Carr in a post on his blog, and “you cannot aggregate [those factors] at the national level and get a meaningful understanding of food insecurity – and certainly not actionable information.”
The same is true when it comes to climate vulnerability. In a report from The Robert S. Strauss Center’s Climate Change and African Political Stability Program, authors Joshua Busby, Todd Smith, and Kaiba White write that “research announcing that ‘Africa is vulnerable to climate change,’ or even ‘Ethiopia is vulnerable,’ without explaining which parts of Ethiopia are particularly vulnerable and why, is of limited value to the international policy community.”
“It is of even less use to Africans themselves, in helping them prioritize scarce resources,” add Busby et al.
Understanding the joint problems of climate change and population growth on a global level helps frame the challenges facing the world as it moves toward 8, 9, and possibly 10 billion. But knowing the ins and outs of how these issues interact on a local level will be a necessary step before policymakers and others can hope to craft meaningful responses that minimize our vulnerability to these challenges over the coming decades.

STATcompiler: Visualizing Population and Health Trends
›World population is growing – earlier this week, the global community symbolically marked the arrival of the seven billionth person. But the unprecedented growth in global population over the last few decades has not affected everyone equally – in 1950, 68 percent of the world’s population lived in developing regions; today that number is 82 percent. MEASURE’s latest version of their STATcompiler tool helps visually highlight areas simultaneously experiencing the most demographic change and poor health indicators.
The revised STATcompiler – released in September – provides new ways for users to visualize data by generating custom data tables, line graphs, column charts, maps, and scatter plots based on demographic and health indicators for more than 70 countries. Users can select countries or regions of interest, and relevant indicators, including for family planning, fertility, infant mortality, and nutrition. Tables can be further customized to view indicators over time, across countries, and by background characteristics, such as rural or urban residence, household wealth, or education. In some cases, sub-national data is available. User-created tables and images are then exportable so that they may be easily used in papers or presentations.
Since STATcompiler is still in active development, certain functions are still being added. HIV data has not yet been integrated into the program, nor has the express viewer function, with customizable, ready-made tables for quick access. Additionally, updated information is not available for all countries, in all categories – for instance, the most recent data available for Mexico comes from a 1987 survey. If preferred, the legacy version remains available to users in the meantime.
MEASURE DHS – the Monitoring and Evaluation to Assess and Use Results Demographic and Health Surveys project – provides technical assistance for data collection on health and population trends in developing countries. Their demographic and health surveys, funded by USAID, provide data for a wide range of monitoring and impact evaluation indicators at the household level in the areas of population, health, and nutrition. They have become a staple data source for researchers, and the addition of better analysis functions and dissemination tools, via STATcompiler, will hopefully help advance understanding of demographic and health trends.
