Youth, Aging, and Governance: A Political Demography Workshop at the Monterey Institute of International Studies
›April 5, 2012 // By Schuyler Null“Demography is sexy – it’s about nothing but sex and death (and migration),” said Rhodes College Professor Jennifer Sciubba at the Monterey Institute of International Studies during a workshop on March 30.
Jack Goldstone of James Madison University, Richard Cincotta of the Stimson Center, and ECSP’s Geoff Dabelko joined Sciubba in a workshop for students and faculty on key developments in political demography. Sciubba and Cincotta were contributors to Goldstone’s recently released edited volume, Demography: How Population Changes Are Reshaping International Security and National Politics.
“Demography is changing the entire economic and strategic divisions of the world,” Goldstone told the room. “We’ve had a 15 year increase in life expectancy just in the last half century,” and today, “90 percent of children under 10 are growing up in developing countries.”
Many countries, said Goldstone, are caught in a difficult race between growth and governance, with governments struggling to provide services and opportunity to their growing populations. This challenge is especially acute in cities, which for the first time in human history are home to the majority of all people.
At the same time, aging is a phenomenon that will affect many developed countries. In the United Sates, the baby boomers are becoming “the grayest generation,” Goldstone said, and similar imbalances between the number of working age people and their dependent elders will soon affect Western Europe, Japan, Korea, Russia, and others.
Re-Examining the Aging Narrative
Some have predicted this “graying of the great powers” will have disastrous consequences for many of the G8, as state pension costs blunt economic growth and innovation, military adventurousness, and global influence, but Jennifer Sciubba presented a case for why fears may be overblown.
When discussing the aging phenomenon in developing countries, many analysts focus too closely on the fiscal environment, argued Sciubba. This creates tunnel vision that ignores the potential coping mechanisms that states have at their disposal. Alliances, for example, are under-accounted for, she said, and closer European Union and even NATO integration could help ameliorate the individual issues faced by aging countries like Germany, France, and Italy.She also pointed to evidence that the developing world’s declining fertility may be have been “artificially depressed” by large proportions of women that delayed pregnancy starting in the 1990s. But now the average age of childbearing has stopped rising. The UN total fertility rate projections for industrialized states for the period 2005 to 2010 was revised upward from 1.35 children per woman in 2006 to 1.64 in 2008 and 1.71 in 2010.
This brings into focus a key leverage point for many developed countries that is not often discussed in traditional conversations about aging: making the workplace friendlier for women. Offering money to couples to have children does not work, said Sciubba – women do not make a simple monetary cost-benefit analysis when they decide to have children. Much more likely is a calculation about the cost to their professional career. Therefore, instituting more liberal leave policies and making it harder for employers to fire both men and women for taking maternity or paternity leave is more likely to have a real impact on fertility rates.
The growing efficiency – and retirement age – of today’s workers can blunt the effect of older workforces on developed economies, said Sciubba. And the stability, strong institutions, and legal protections for innovation are all advantages that will continue to attract the best and the brightest from developing countries.
The competing phenomena of aging in the developed world and continued growth in the developing – which some have dubbed the “demographic divide” – will likely make immigration a very important, possibly friction-inducing issue in the coming decades. Goldstone pointed to the challenges Europe is having today coping with immigrants from North Africa and the Middle East as a possible harbinger of things to come.
Applying Demographic Theory: The Age Structural Maturity Model
While many regions will continue to experience population growth for the next two decades, including sub-Saharan Africa, the Middle East, and parts of East and South Asia and Latin America, the overall global trend is towards older populations. This is good news for democracy, according to Richard Cincotta.
Cincotta, who consults with the National Intelligence Council on demographic issues, explained his “age structural maturity” model, which finds a historical correlation between the median age of countries and their Freedom House scores (an annual global assessments of political rights and civil liberties). Older populations tend to have more liberal regimes, while the opposite is true in younger populations. Combining this model with demographic projections, one can predict when it will become likely for democracy to emerge as a country ages. Before the Arab Spring – to some disbelief at the time – Cincotta used the model to predict that Tunisia would reach a 50/50 chance of achieving liberal democracy in 2011 (see more on this in his posts about Tunisia and the Arab Spring).
For those youthful countries that do achieve some level of liberal democracy, the model predicts they have a high likelihood of falling back towards authoritarianism (Mali is a tragic recent example).
This model, said Cincotta, can be a useful tool for analysts to challenge and add to their assessments. For example, it paints a bleak picture for democracy in Afghanistan (median age 16.6 years old), Iraq (18.5), or Yemen (17.7) and a comparatively rosier one for Tunisia (29.8), Libya (26.1), and Egypt (25.0). Some other observations may useful as well: no monarch has survived without some limits of power being introduced after countries reach a median age of 35, and military rulers too never pass that mark.
The age structural maturity model is, however, not perfect, Cincotta said. The most common outliers are autocracies (Freedom House score of “not free”) and partial democracies (“partly free”) with one-party regimes (China, North Korea), regimes led by charismatic “founder figures” (Cuba, Singapore), or those that where the regime is either supported or intimidated by a nearby autocratic state (Belarus).
Like all analyses, the model has its limitations, said Cincotta, but if used as a tool to generate “alternative hypotheses,” it can help predict dramatic political changes, like the Arab Spring. The research also suggests that the “third wave” of democratization is not over and will in fact continue to expand as countries with younger populations mature.
In conclusion, the panelists recommended the students find ways to include political demography in their work moving forward. “Consider it an alternative tool that may be useful,” said Geoff Dabelko. Policymakers today are overburdened with information and conventional analyses can sometimes become stuck in familiar lines of thought – demography can supplement these or shake them up by providing alternative narratives.

Taking Stock of Past and Current Demographic Trends
›March 29, 2012 // By Kayly OberECSP is at London’s 2012 Planet Under Pressure conference following all of the most pertinent population, health, and security events.
“Demography is a science of assumptions,” said Sarah Harper, a demographer at the University Oxford, during a panel at the Planet Under Pressure conference. Thirty years ago, she said, demographers believed the world would reach 24 billion by 2050, now the latest UN median projections predict 10 billion. That means a lot of progress has been made for families and development as a whole, but there are some obstacles yet.
Harper stressed that the development community should focus on parts of the world with stubbornly high fertility rates, particularly sub-Saharan Africa. If total fertility rates came down there by 2050, below the expected four children per woman, the region could be home to as many as a billion fewer people than current projections. The earlier we acknowledge this growth, the easier it will be to offer interventions like family planning and reproductive health to hedge it, she said.
Additionally, demographers need worry about important changes in modern population and environment dynamics.
As Harper notes in an interview with ECSP (video below):There has been so much hype around population growth that I think we’ve ignored the other characteristics of population…that it’s changing in its density – we’re all becoming more urban; it’s changing in its distribution – we’re becoming more mobile; and it’s also changing in its composition – the world is getting older.
Sir John Sulston of the Royal Society agreed: population is a more-nuanced subject than many can digest. “Population has been much too ignored because it’s difficult,” he said.
I think it’s very clear that these changes are going to interact with the environment and be affected by environmental change but are also going to impact upon future environmental change.
Sulston urged us to look not just at the diversity of the world, but also the inequity. Today, there is “inequity in countries, between countries, and between generations.”
There is no silver bullet – the international community need to look at three components in concert if we want to make a difference, he said: first, bring down infant mortality; second, invest in family planning; and third, emphasize education for women.“It’s not about surviving, it’s about flourishing,” Sulston said.
When the ECSP delegation isn’t attending plenary and breakout sessions here at the conference, we’re manning our Wilson Center information booth. And over the last few days, we’ve had the pleasure of introducing our work to a number of new faces, including curious faculty, energetic students, and hopeful doctoral candidates. If you’re attending please feel free to stop by.
Expect more updates from East London, including more short video interviews, in the next three days as ECSP highlights the unique perspectives coming out of the Planet Under Pressure conference.

Demography, Climate in the Spotlight at Planet Under Pressure
›March 27, 2012 // By Kayly OberLondon’s 2012 Planet Under Pressure conference, on all things global change – including climate, population, global risks, and food security – kicked off with a bang on March 26 and ECSP was there to cover it. We’ll be here throughout the week following all of the most pertinent population, health, and security events – we invite you to visit our booth if you happen to be in London, join the conversation on Twitter (#Planet2012), and/or watch the livestream.
During the opening plenaries, UK Scientific Advisor and all-around environmental all-star Sir John Beddington was the first to introduce population into the discussion.
Speaking on “The Planet in 2050” panel, Beddington immediately noted that really 2050 is too far out and instead we should focus on the next two decades. Within these 20 years the trajectory of greenhouse gas emissions and climate change will be determined by the extent and manner of urbanization and demographic changes, particularly in Africa.
“How are we going to generate an infrastructure to feed 500 million Africans in the next 13 years?” Beddington asked.
Beddington’s talk could be considered a rejoinder to his famous “perfect storm” analogy, outlined in The Guardian in 2009:Our food reserves are at a 50-year low, but by 2030 we need to be producing 50 percent more food. At the same time, we will need 50 percent more energy, and 30 percent more freshwater.
In a later session, “Securing Global Biodiversity,” Simon Stuart, chair of the species survival commission of the International Union for Conservation of Nature (IUCN), expanded on this “perfect storm” analogy.
There are dramatic problems out there, particularly with water and food, but energy also, and they are all intimately connected. You can’t think about dealing with one without considering the others. We must deal with all of these together.
He agreed that the global challenge of our day hinged on how human needs add pressures to the natural environment. Rising demand for energy, food, and freshwater not only influences climate change but also exerts unprecedented pressure on soil quality and biodiversity.
But although we’re impeded by major challenges, including “unsustainable economic models,” a lack of public support, and a massive need for investment in conservation, we have made some strides, Stuart said. The Convention on Biological Diversity’s strategic plan for biodiversity, established in 2010, sets 20 targets for biodiversity conservation by 2020. Stuart believes this is the beginning of acknowledging the urgency of addressing the threat to biodiversity.
Tim Coulson, professor of population biology at Imperial College London, compared the efficiency of either reducing fertility rates or per capita consumption to determine the best way to reduce humanity’s impact on the planet.
Coulson ran two simple simulations using India and the United States as case studies. In one model, he changed fertility rates by one percent per year for 50 years. In the other, he decreased per capita consumption by one percent per year for 50 years. What he found in both cases was that decreasing per capita consumption achieved the most rapid change in human impact on the environment. Nevertheless, he acknowledged that a longer-term course of action of declining fertility rates was needed to keep impact stable.
Readers beware, however – this type of experiment is an incredibly simplified exercise in the intersection of people and the environment. A more varied set of scenarios would produce more useful results. As Beddington mentioned, populations in sub-Saharan Africa have both the highest growth rates and the most direct impact on the environment due to their higher reliance on natural resources for livelihoods.
And, perhaps most importantly, as one commentator noted, these scenarios do not take into account cost factors. For instance, in order to reduce greenhouse gas emissions through more energy efficient buildings and transport, the United States would need to invest $1.1 trillion through 2030. Alternatively, the cost to provide for the 215 million women in developing countries who want to avoid pregnancy but are not using an effective means of contraception is estimated at $3.6 billion. Using the “wedge” climate model, meeting unmet family planning needs would be equivalent to the amount of greenhouse gas emissions saved by converting entirely to electric vehicles – at a fraction (about five percent) of the cost.
Stay tuned for more updates from ECSP at the Planet Under Pressure Conference. We’ll also be posting pictures from the conference to our Facebook and Flickr pages.

Global Water Security Calls for U.S. Leadership, Says Intelligence Assessment
›March 26, 2012 // By Schuyler Null
Alongside and in support of Secretary Clinton’s announcement of a new State Department-led water security initiative last week was the release of a global water security assessment by the National Intelligence Council and Director of National Intelligence. The aim of the report? Answer the question: “How will water problems (shortages, poor water quality, or floods) impact U.S. national security interests over the next 30 years?”

Fourth World Water Development Report Released by UN
›The beginning of last week’s World Water Forum in Marseille also marked the release of UNESCO’s fourth edition of the World Water Development Report. Chief amongst the challenges outlined in the new report are meeting demand from growing population and consumption. Agriculture accounts for 70 percent of water usage, according to the report, and globally we will require 70 percent more food over the next 40 years, introducing the possibility of overtaxing already-stressed water resources – all while adapting to climate change. There are substantial gains to be had in increasing farm-to-table efficiency, especially in developing countries, the authors sagely point out, but the supply challenge remains a huge one.
This year’s edition also adds several new sections, including on women and water. “The crisis of scarcity, deteriorating water quality, the linkages between water and food security, and the need for improved governance are the most significant in the context of gender differences in access to and control over water resources,” write the authors. “These challenges are expected to become more intense in the future.”
The integrated nature of today’s water issues is a highlight throughout the report. “Accelerated change” will create new threats and “interconnected forces” create uncertainty and risk, but UNESCO emphasizes that if policymakers are made aware of these issues, ultimately “these forces can be managed effectively and can even generate vital opportunities and benefits through innovative approaches to allocation, use, and management of water.”

Hotspots: Population Growth in Areas of High Biodiversity
›More than one-fifth of the world’s population lives in biodiversity hotspots – “areas that are particularly rich in biodiversity and endemic species,” said John Williams of the University of California, Davis, at the Wilson Center on February 29. And those populations are growing faster than the global average. Add to that the fact that “biodiversity continues to decline globally, despite increasing investments in conservation,” said David Lopez-Carr of the University of California, Santa Barbara, and the need for new approaches to conservation becomes evident. [Video Below]
Williams and Lopez-Carr were joined by Dr. Vik Mohan, director of the sexual and reproductive health program for Blue Ventures, a London-based conservation nongovernment organization that works with communities on the remote western coast of Madagascar.
To respond to the demands of the communities and to better protect biodiversity hotspots, the speakers argued that conservation efforts need to incorporate health and livelihood services directed at the growing populations living nearby.
A Complex Relationship
“The relationship between population and biodiversity loss or conservation is a pretty complex relationship,” said Williams.
He offered Latin America and the Caribbean as an example of the multiple factors that can affect how population and biodiversity interact. Population growth in the region has slowed, and agricultural expansion is driving habitat loss as the population ages and urbanizes and as increasing per capita GDP contributes to higher levels of consumption.
In the Indo-Pacific region, stretching from East Asia to Australia, high population growth coupled with economic growth has coincided with an increase in the exploitation of rare species for illegal trade, according to Williams. And in Africa, where the population is growing quickly but without comparable economic growth and amid high levels of instability, subsistence drives ecological exploitation.
Biodiversity and Family Planning in Madagascar
“People who live in the biodiversity hotspots are typically poorer, typically have poorer access to healthcare than their counterparts in the cities or in the world at large, and typically have poorer health than those counterparts,” said Mohan.
Blue Ventures has been working in Madagascar since 2003. The island is one of the most biodiverse areas in the world; 80 percent of its plant and animal life is endemic, meaning it exists there and nowhere else, said Mohan. At the same time, Madagascar is one of sub-Saharan Africa’s fastest growing countries, with a population growth rate of 2.9 percent and an average total fertility rate of 4.6 children per woman.
Blue Ventures initially came to the country to improve conservation in the island’s coastal villages, where residents survive largely on subsistence fishing. But once there, the group quickly found that the population was “growing so rapidly that in spite of our best conservation efforts, the demand for those finite coastal resources [was] outstripping supply,” said Mohan.
“The number of people who are going out to catch fish to feed their to feed their families is going up exponentially, and those fisherman are having to work harder and harder to catch smaller fish that are farther and farther down the food web.”
Realizing that trend, Mohan said that “just by asking a few very basic questions, we unearthed a huge unmet need for healthcare and a huge unmet need for family planning in particular.”
In response, Mohan and his colleagues opened up a family planning clinic in Andavadoaka, one of the villages Blue Ventures serves. On the clinic’s first day, Mohan said, “20 percent of all women of reproductive age came asking for contraception.” Following that opening, they “rapidly found [that] this unmet need was mirrored in every single village along the coast that we worked in,” he said. Since then, modern contraceptive prevalence, initially about seven percent, has increased four-fold, while birth rates have fallen by about one-third. All in all, Mohan said, the population of the Velondriake region, where Blue Ventures operates, is five percent smaller now than it would have been without the group’s family planning services.
Rural Areas Driving Population Growth
Across the developing world, Lopez-Carr said that unmet need for family planning “remains significantly higher” in biodiversity hotspots. Given that high unmet need, especially in Africa, it is easy to infer that “conservation may be less sustainable…if it does not consider health,” he said.
In his ongoing research on population and biodiversity, Lopez-Carr looks at how fertility rates compare in and out of hotspot areas and between regional and local levels. At the country and province level, “high-value conservation areas do not have unusually high total fertility rates (TFRs),” he said. But at more localized levels, “in the most remote rural areas, TFRs remain high, and in many cases, in the most remote rural areas, the demand for family planning is still very low,” indicating that these areas are still in the early stages of their demographic transitions.
The fact that the sub-state picture can look so different from the state-level picture means that there is more work for researchers to do, said Lopez-Carr. “Where the fertility rates are highest is where we have the least data,” he said, and that has significant implications for understanding future population growth.
Looking at UN population projections, the world’s net population gains will be in its poorest cities, he said, but “virtually all this growth is going to be from migration, fueled by remaining high fertility in rural areas.” And “virtually all of that growth will be predicated upon the timing, magnitude, [and] pace of the fertility transition in rural areas.”
Better understanding the demographic picture in rural areas is therefore critical – not just to improving health and preserving biodiversity in the world’s hotspots, but to honing down more accurate global population projections as well.

Food Security in a Climate-Altered Future, Part Two: Population Projections Are Not Destiny
›March 20, 2012 // By Kathleen MogelgaardRead part one, on the food-population-climate vulnerability dynamics of Malawi and other “hotspots,” here.
Too often, discussions about future food security make only a passing reference to population growth. It is frequently framed as an inevitable force, a foregone conclusion – and a single future number is reported as gospel: nine billion people in 2050. But adhering to a single path of future population growth misses the opportunity to think more holistically about food security challenges and solutions. Several recent food security reports illustrate this oft-overlooked issue.
Accounting for Population a Challenge
Oxfam International’s Growing a Better Future: Food Justice in a Resource-Constrained World is a thorough and fascinating examination of failures in our current food system and future challenges related to production, equity, and resilience. It reports newly-commissioned research, carried out by modelers at the Institute of Development Studies, to assess future agricultural productivity and food prices given the anticipated impacts of climate change.
But both the modeling work and the report text utilize a single projection for population growth: the UN’s 2008 medium variant projection of 9.1 billion by 2050 (which has since been revised by the UN up to 9.3 billion). Early on, the report does recognize some degree of uncertainty about this number: “Greater investment in solutions that increase women’s empowerment and security – by improving access to education and health care in particular – will slow population growth and achieve stabilization at a lower level.” But such investments do not appear in the report’s overall recommendations or Oxfam’s food security agenda. This is perhaps a missed opportunity, since the range of possibilities for future population growth is wide: the UN’s low variant for 2050 is 8.1 billion, and the high variant is 10.6 billion.
Food Security, Farming, and Climate Change to 2050: Scenarios, Results, and Policy Options is another frequently-cited report published by the International Food Policy Research Institute in 2010. In recognizing that economic growth and demographic change have important implications for future food security, IFPRI researchers modeled multiple scenarios for the future: an “optimistic” scenario which embodies high GDP growth and low population growth, a “pessimistic” scenario with low GDP growth and high population growth, and a “baseline” scenario which incorporates moderate GDP growth and the UN’s medium population projection. Each of these scenarios was then combined with five different climate change scenarios to better understand a range of possible futures.
Using different socioeconomic scenarios enabled researchers to better understand the significance of socioeconomic variables for future food security outcomes. The first key message from the report is that “broad-based economic development is central to improvements in human well-being, including sustainable food security and resilience to climate change.” This focus on economic development is based in part on the “optimistic scenario,” which counts on high GDP and low population growth (translating to high rates of per capita GDP growth).
Unfortunately, the socioeconomic scenario construction for this analysis doesn’t allow for an independent assessment of the significance of slower population growth, since high population growth is paired only with low GDP and lower population growth is paired only with high GDP. Therefore, none of the report’s recommendations includes reference to reproductive health, women’s empowerment, or other interventions that would contribute directly to a slower population growth path.
Expanding the Conversation to Better Inform Policy
Without a more nuanced treatment of population projections in technical analysis and popular reporting on food security, decision-makers in the realm of food security may not be exposed to the idea that population growth, a factor so critical in many areas where food security is already a challenge, is a phenomenon that is responsive to policy and programmatic interventions – interventions that are based on human rights and connected to well-established and accepted development goals.
There are some positive signs that this conversation is evolving. A new climate change, food security, and population model developed by the Futures Group enables policymakers and program managers to quickly and easily assess the impact of slower population growth on a country’s future food requirements and rates of childhood malnutrition. In the case of Ethiopia, for example, the model demonstrates that by 2050, a slower population growth path would make up for the caloric shortfall that is likely to arise from the impact of climate change on agriculture and would cut in half the number of underweight children.
And recently, we’ve begun to see some of this more nuanced treatment of population, family planning, and food security linkages in a riveting, year-long reporting series (though perhaps unfortunately named), Food for 9 Billion, a collaboration between American Public Media’s Marketplace, Homelands Productions, the Center for Investigative Reporting, and PBS NewsHour.
In January, reporter Sam Eaton highlighted the success of integrated population-health-environment programs in the Philippines, such as those initiated by PATH Foundation Philippines, that are seeing great success in delivering community-based programs that promote food security through a combination of fisheries management and family planning service delivery. Reporting from the Philippines in an in-depth piece for PBS NewsHour, Eaton concluded:So maybe solving the world’s food problem isn’t just about solving the world’s food problem. It’s also about giving women the tools they want, so they can make the decisions they want – here in the world’s poorest places.
Making clear connections of this nature between population issues and the most pressing challenges of our day may be the missing link that will help to mobilize the political will and financial resources to finally fully meet women’s needs for family planning around the world – an effort that, if started today, can have ongoing benefits that will become only more significant over time. Integrating reproductive health services into food security programs and strategies is an important start.
Back in Malawi, just before we turned off the highway to the Lilongwe airport, I asked the taxi driver to pull over in front of a big billboard. We both smiled as we looked at the huge government-sponsored image of a woman embracing an infant. The billboard proclaimed: “No woman should die while giving life. Everyone has a role to play.” Exactly. The reproductive health services that save women’s lives are the same services that can slow population growth and bring food security within closer reach. -
Food Security in a Climate-Altered Future, Part One: “Hotspots” Suggest Food Insecurity More Than a Supply Problem
›March 20, 2012 // By Kathleen MogelgaardSmall talk about the weather with my Malawian taxi driver became serious very quickly. “We no longer know when the rains are coming,” he said as we bumped along the road toward the Lilongwe airport last November. “It is very difficult, because we don’t know when to plant.”
These days, he is grateful for his job driving a taxi. His extended family and friends are among the 85 percent of Malawians employed in agriculture, much of which is small-holder, rain-fed subsistence farming. Weather-related farming challenges contribute to ongoing food insecurity in Malawi, where one in five children is undernourished.
His observations of the recent changes in climate match forecasts for the region: In East Africa, climate change is expected to reduce the productivity of maize – Malawi’s main subsistence crop – by more than 20 percent by 2030, according to a recent analysis by Oxfam International.
I looked out the window at dusty fields and tried to imagine what Malawi might look like in 2030. For one thing, it will be more crowded. A lot more crowded. According to UN population projections, by 2030, Malawi’s population will have grown from about 15 million today to somewhere between 26.9 and 28.4 million. With climate change dampening agricultural productivity and population growth increasing food demand, how will Malawians – many of whom don’t have enough to eat now – have enough to eat in the future?
It gets quiet in the taxi as the driver and I both ponder this question. Malawi is not alone in being a climate-vulnerable country with a rapidly growing population dependent on rain-fed agriculture. Population Action International’s Mapping Population and Climate Change tool shows us that many “hotspot” countries – scattered across Latin America, Africa, and Asia – face the triple challenge of low climate change resilience, projected decline in agricultural productivity, and rapid population growth.
Agricultural trade, government safety net programs, and foreign assistance will no doubt continue to play an important role in the quest for food security in Malawi and other “hotspot” countries in the future. And climate change adaptation projects will, hopefully, reshape agricultural practices and technologies in ways that can boost yields and enable crops to better withstand temperature and precipitation fluctuations.
These interventions will be critical in addressing the supply side of future food security challenges. But what about growing demand?
Malthus Revisited?
Juxtaposing population growth with food production does, of course, bring us back to Thomas Robert Malthus’ original (and by now somewhat infamous) dire warning: that population growth would eventually outrun food supply. But seeing the scale of the challenges in Malawi firsthand, I must admit that my inner Malthus sat up and took notice.
It is true that technological advances have enabled astounding growth in agricultural yields that have enabled us to feed the world in ways the doom-filled Malthus could never have imagined in the early 19th century. But it is also true that the agricultural productivity gains that helped us keep pace with population growth for so long are beginning to slow: According to the U.S. Department of Agriculture, aggregate agricultural yields averaged 2.0 percent growth annually between 1970 and 1990, but that growth in yields declined to 1.1 percent between 1990 and 2007, and is projected to decline to less than 1.0 percent in the years to come.
This comes at a time when the Food and Agriculture Organization reports that food production will need to increase by 70 percent by 2050 in order to adequately feed a larger, wealthier, and more urbanized population.
To dismiss any talk of population growth as outmoded Malthusian hand-wringing misses an opportunity to embrace interventions that can contribute significantly to prospects for future food security – namely, empowering women with information and services that enable them to determine the timing and spacing of their children.
In Malawi and many of the “hotspot” countries around the world, high proportions of women remain disempowered in this regard. Meaningful access to family planning and reproductive health services results in smaller, healthier families that will be better equipped to cope with the food security challenges that are headed their way.
Not only does a smaller family mean that limited household resources go further, but access to family planning and reproductive health services is connected to other important education and economic outcomes.
A new Population Reference Bureau policy brief, for example, highlights how improving women’s reproductive health will not only lead to declining fertility and slower population growth in sub-Saharan Africa, but can also contribute to balancing a woman’s many roles (agricultural producer, worker, mother, caregiver, etc.) in ways that support greater food security for her family. And research by the International Food Policy Research Institute shows that in developing countries, women’s education and per capita food availability are the most important underlying determinants of child malnutrition – with women’s education having the strongest beneficial impact. Access to family planning paves the way for these outcomes – and by slowing population growth, can help to slow the growth in food demand.
Women’s Needs and Future Food Demand
The scale of potential benefits of meeting women’s family planning needs is significant when thinking about future food demand, both globally and especially in food insecure, climate-vulnerable countries. As we have seen in Malawi, there is a range of possible future population sizes and that range grows even wider when the projections are extended to 2050: According to the UN, Malawi’s 15 million today will grow to somewhere between 45 million and 55 million by 2050.
That span of 10 million people embodies assumptions about declining fertility in Malawi. To reach 55 million, the average number of children per woman would need to drop from 5.7 today to 4.5 by 2050. If fertility drops further, to 3.5 children per woman, Malawi’s population would grow to (only) 45 million. Where Malawi ends up in that 10-million-person population spread will have deep implications for per capita food availability, not to mention other important development outcomes.
Fertility declines of this kind do not require coercion or “population control.” As we have seen time and again, when women are empowered with information and services that enable them to determine the timing and spacing of their children, smaller, healthier families are the inevitable result.
Meeting women’s needs for reproductive health and family planning services is not – and never should be – about reducing population size. Universal access to reproductive health is recognized as a basic human right and central development goal (embodied in Millennium Development Goal 5) because of its vital connections to women’s and children’s health, education and employment opportunities, and poverty alleviation. And yet, too many women remain without the ability to effectively plan their families. In Malawi, one in four married women would like to delay their next birth or end child-bearing all together but aren’t using contraception; globally, 215 million have this unmet need.
As global efforts ramp up to address interlinked challenges of food security and climate change adaptation, assessing the role of population growth is more important than ever. And in designing strategies to address these challenges – strategies like the U.S. Government’s Feed the Future Initiative and UN-supported National Adaptation Plans – we should not pass over opportunities to incorporate interventions to close the remaining gap in universal access to family planning, especially in places like Malawi and other “hotspot” countries (such as Haiti, Nigeria, and Nepal), where women’s unmet family planning needs are high and population growth is rapid.
