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.

Finding the Link Between Water Stress and Food Prices
›March 19, 2012 // By Wilson Center StaffThe original version of this article, by Lakis Polycarpou, appeared on State of the Planet.
Over the past decade, average global food prices have more than doubled, with 2008 and 2010 seeing excruciating price spikes that each had far-reaching economic, geopolitical, and social consequences.
What explains this long-term trend – and why did prices spike so much higher in the years that they did?
For policymakers at all levels, answering that question is of vital importance if there is to be any hope of feeding the world’s growing population in the coming decades, much less maintaining social order.
According to recent research by the New England Complex Systems Institute, spikes in food prices are so closely correlated with social unrest that they were able to identify a particular food-price threshold above which food riots are very likely.
The most obvious cause for high food prices is oil – in fact, charts showing the correspondence between food and oil prices show an eerie overlap, especially in the last half decade. Water scarcity and climate are major players as well, however. According to the just released United Nations World Water Development Report, demand for water will grow by 55 percent in the next 40 years, and farmers will need 19 percent more water by 2050 just to keep up with growing food demands.

John Williams: Helping People and Preserving Biodiversity Hotspots
›March 16, 2012 // By Schuyler Null“Both humans and the number of species in the world are not evenly distributed across the globe,” said John Williams of the University of California, Davis, who recently spoke at the Wilson Center about his contribution to Biodiversity Hotspots: Distribution and Protection of Conservation Priority Areas. “In particular we find that species diversity is concentrated in what’s called the biodiversity ‘hotspots.’”
Largely in the tropics, Mediterranean climates, and along mountain chains, biodiversity hotspots are “where there’s a real concentration in number of species and also unique species – plants and animals that exist nowhere else on Earth,” he said.
“It’s a very complex relationship between biodiversity and human population, because it’s not necessarily [true] that places of high human population are a threat to biodiversity,” said Williams. Many different factors play a role, “like education, like consumption, like economic development, different cultures – how people interface with the natural world – all these things create nuances as far as what that relationship is between biodiversity and where people live.”
“There are some basic things we can do that are going to be good for human welfare, as well as biodiversity,” he continued. A few are addressing lack of education, especially among girls, in areas of high biodiversity; providing basic health services, including family planning, where rural growth rates are highest; and improving physical access to rural areas to promote economic development.
“We see there’s a direct correlation between each additional year of schooling a girl has and their fertility during their lifetime,” Williams said. “As people climb out of poverty, they also choose to have smaller, healthier families.” -
Africa’s Demographic Challenges, Genderizing Food Security and Climate Responses
›Gender and Climate Change Research in Agriculture and Food Security for Rural Development is a detailed training guide produced by the CGIAR Research Program on Climate Change, Agriculture and Food Security and the Food and Agricultural Organization of the United Nations (FAO). The guide’s purpose is to support “work to investigate the gender dimensions of responding to climate change in the agriculture and food sectors…to improve food production, livelihood security and gender equality.” The authors write that “the number of hungry people in the world could be reduced by more than 100 million if women in rural areas were given equal access to the same resources as men.” The guide focuses on sensitizing researchers and practitioners “to the links between socio-economic and gender issues” and provides a suite of tools for gathering data about the gender and climate change aspects of agricultural development. Along with concrete tools to understand and address gender inequities in agricultural development, the report adopts a nuanced social definition of gender in which “people are born female or male, but learn to be women and men,” keeping the focus squarely on the socio-economic and political barriers to full equality.A report from the Berlin Institute for Population and Development, Africa’s Demographic Challenges: How A Young Population Can Make Development Possible, argues that “if mortality and fertility decrease” across the African continent, there will be a “demographic bonus.” If nurtured through ample investment in human capital, this bonus may become a “demographic dividend,” as growing numbers of working-age people participate in the economy. The report argues that taking advantage of this demographic window, however, requires policy actions that both encourage fertility reductions and foster economic development throughout the continent, declaring boldly that “high birth rates and development are mutually exclusive.” Thus, according to the authors, the pathway to development is supporting the empowerment and education of women and girls, strengthening reproductive health services, and ensuring that both young women and young men are able to engage socio-economically within their societies. Though the report’s argument that demographic change can be critical for development is convincing, the form, strength, and causal direction of these linkages at times becomes confused. -

Central Asia’s Dam Debacle
›March 13, 2012 // By Wilson Center StaffThe original version of this article, by Eelke Kraak, appeared on ChinaDialogue.
The Toktogul Dam in Kyrgyzstan is an imposing structure. The dam guards the largest and only multi-annual water reservoir in central Asia. The cascade of five hydroelectric stations downstream produces 90 percent of Kyrgyzstan’s power. Cotton fields thousands of kilometers away in Kazakhstan and Uzbekistan depend on the release of water from this dam.
The Toktogul is literally and figuratively the “valve” of the Syr Darya River. But by relying on large-scale engineering projects to control the river, these countries have ignored the fundamentally political nature of water management.
The significance of the Toktogul dam goes beyond its economic benefits. It was the center piece of the Soviet Union’s efforts to conquer nature in its drive to modernize central Asia. When it became fully operational in the late 1980s, the project to control the region’s rivers seemed complete.
But the costs have been high. The Aral Sea, the terminal lake of the main sources of water in central Asia, the Syr Darya and Amu Darya rivers, has shrunk to almost nothing. Many areas surrounding what is left of the lake are heavily polluted. Moreover, the now independent Syr Darya riparian countries – Kyrgyzstan, Uzbekistan, Tajikistan and Kazakhstan – disagree on how the Toktogul should be operated.

Women’s Health: Key to Climate Adaptation Strategies
›The discussion about family planning and reproductive rights “needs to be in a place where we can talk thoughtfully about the fact that yes, more people on this planet – and we’ve just crossed seven billion – does actually put pressure on the planet. And no, it is not just black women or brown women or Chinese women who create that problem,” said Kavita Ramdas, executive director for programs on social entrepreneurship at Stanford University.

Ethiopia Provides Model for Improving Climate, Other Data Services in Africa
›The original version of this article appeared on the International Research Institute for Climate and Society (IRI).
In developed countries, we are accustomed to having access to long and detailed records on weather and climate conditions, demographics, disease incidence, and many other types of data. Decisionmakers use this information for a variety of societal benefits: they spot trends, fine-tune public health systems, and optimize crop yields, for example. Researchers use it to test hypotheses, make forecasts, and tweak projections from computer models. What’s more, much of these data are just a mouse click away, for anyone to access for free (see examples for climate and health).
Across much of Africa, however, it’s a different story. By most measures, Africa is the most “data poor” region in the world. Wars and revolutions, natural and manmade disasters, extreme poverty, and unmaintained infrastructure, have left massive gaps in socioeconomic and environmental data sets. Reliable records of temperature, rainfall, and other climate variables are scarce or nonexistent. If they do exist, they’re usually deemed as proprietary and users must pay to get access. This is not an inconsequential matter. Without readily available, reliable data, policy makers’ ability to make smart, well-informed decisions is hobbled.
The problem of data access persisted even in Ethiopia, regarded as having one of the better meteorological services on the continent. Thanks to the recent efforts of Tufa Dinku, a climate scientist at the International Research Institute for Climate and Society, the situation has improved considerably.

More People, Less Biodiversity? The Complex Connections Between Population Dynamics and Species Loss
›March 8, 2012 // By Laurie Mazur“For if one link in nature’s chain might be lost, another and another might be lost, till this whole system of things should vanish by piece-meal.”
~ Thomas Jefferson, 1799This much is clear: As human numbers have grown, the number of species with whom we share the planet has declined dramatically. While it took about 200,000 years for humanity to reach one billion people around 1800, world population has grown sevenfold since then, surpassing seven billion last year.
