‘Global Trends 2030’ Author Mathew Burrows Describes Demographic and Environmental Megatrends
›
“The world of 2030 will be radically transformed from our world today,” reads the opening of Global Trends 2030: Alternative Worlds, produced by the National Intelligence Council. In this podcast, principal author Mathew Burrows breaks down some of the scenarios discussed in the report, and describes how demographic and environmental trends – two of four “megatrends” – could play out over the next few decades.

Jack Goldstone Discusses Future Demographic Trends: The Old, the Young, and the Urban
›In this podcast, Jack Goldstone of George Mason University discusses the world’s demographic stresses in the coming years. In parallel to a growing trend of population aging in developed countries, much of the world will remain young, growing, and urbanizing, he said. The choices these growing countries make over the next few decades will have reverberating effects for the rest of the world, from conflict potential to the spread of stable democracies.

Sam Eaton Describes Population-Food-Environment Links in Rural Philippines
›
In this podcast, journalist Sam Eaton describes the process of producing two pieces that aired on Marketplace and NewsHour last year on the connection between population, the environment, and food security in the Philippines. Eaton visited the rural village of Humayhumay where PATH Foundation Philippines, Inc., has a pilot program distributing contraceptives and teaching community members about conservation and sustainable livelihoods. Although Eaton said he was at first hesitant to tackle such an “abstract concept” as integrated population, health, and environment development, he found on the ground that it had “all the elements of a good story” and there were tangible benefits visible within the community. Eaton discussed his reporting at the Wilson Center on January 28.

Janani Vivekananda on Strengthening Resilience to Climate Variability in South Asia
›“Building resilience should help address the root causes of vulnerability, creating increased capacity to be able to adapt to a range of possible climate futures, not just cope with… specific climate impacts,” says International Alert’s Janani Vivekananda. Otherwise, if the specific impacts don’t play out, “in a fragile context that could be quite destabilizing and seen as a wasted opportunity.”

Peter Thomson on the Big International Environment and Energy Stories of 2013
›Increasing energy demands around the world will mean a continuing focus on other fuel sources and climate change, said Peter Thomson of PRI’s The World, including the use of coal in countries like China and the safety of hydraulic fracturing and nuclear power. Other areas to watch include water, agriculture, and possible tipping points like dieback in the Amazon rainforest.

Hania Zlotnik Discusses Changes to Latest UN Population Projections
›Former UN Population Division Director Hania Zlotnik spoke recently at the Wilson Center discussing last year’s highly-publicized UN world population projections and explaining the methodology behind the figures. “The latest projections are very special,” she said, adding that “we think that this methodology is a lot better than what we had before.”
What accounts for such improvement? Zlotnik said it has a lot to do with greater availability of data. “The UN has been…mandated by governments to produce population estimates since the 1950s,” she stated, and they have refined their projections process over the years based on an increasing record of data and identification of some “patterns that can inform the future.”Former UN Population Division Director Hania Zlotnik spoke recently at the Wilson Center discussing last year’s highly-publicized UN world population projections and explaining the methodology behind the figures. “The latest projections are very special,” she said, adding that “we think that this methodology is a lot better than what we had before.”
What accounts for such improvement? Zlotnik said it has a lot to do with greater availability of data. “The UN has been…mandated by governments to produce population estimates since the 1950s,” she stated, and they have refined their projections process over the years based on an increasing record of data and identification of some “patterns that can inform the future.”
The increasingly large dataset accumulated during this process is particularly important because of what Zlotnik called “inertia” in population change. “There’s something called ‘population momentum,’ where the population changes on the basis of how many people have already been accumulated on the planet,” she explained, pointing out that many of the people included in the UN’s population projections for 2050 have already been born.
This inertia helps make population projections fairly accurate, but last year’s projections differed from previous efforts in two significant ways.
First, the UN Population Division provided projections not just to 2050 but also to 2100. These more long-term projections estimated an end-of-century population of more than 10 billion – notably higher than previous reports, which had predicted that population would stabilize mid-century at around nine billion.
Second, the underlying methodology used shifted from a deterministic to a probabilistic approach that, according to Zlotnik, does a better job capturing variability in each country’s fertility rate over the next century. “Essentially,” she explained, “a model was developed for every country that takes into account the past path of fertility change [and] also takes into account changes that have happened in other countries…Then [it] does a simulation for the future for every country, in which 100,000 paths are projected, essentially by throwing dice, and then the central path of those 100,000 is used to project the future.”
Zlotnik cautioned that projecting so far into the future is an inexact – albeit necessary – science: “Of course, as we go further into the future, the numbers are more subject to uncertainty. But [the long-term projections] help us give people a better feeling of how important it is to change trends from here to 2050, so that we ensure that, at the end of the century, the number of people on the planet is sustainable.”
“In order to make sure that the population projections made by the United Nations [are realized],” Zlotnik said, “it’s very important that fertility continues to decline, and especially that fertility decline happens in the countries that still have very high fertility.”
“Fertility decline happens in many ways,” she continued, “but the immediate reason why fertility can be reduced is that more people use modern methods of contraception.” -
Jack Goldstone on Post-Cold War Trends in Armed Conflict and Challenges for the World’s Youth
›“Global trends in armed conflict have really come down since the end of the Cold War,” said George Mason University’s Jack Goldstone in this talk adapted from a presentation at the Wilson Center last fall. This drop is a reflection of decreased proxy conflicts between the Soviet Union and United States and increased interventionism from the international community. But another thing we can point to is that the world’s youth population has also declined, he said.“Global trends in armed conflict have really come down since the end of the Cold War,” said George Mason University’s Jack Goldstone in this talk adapted from a presentation at the Wilson Center last fall. This drop is a reflection of decreased proxy conflicts between the Soviet Union and United States and increased interventionism from the international community. But another thing we can point to is that the world’s youth population has also declined, he said.
“There seems to be a reasonably strong connection, between the drop-off in post-Cold War conflicts” and a decline in the proportion of youth in global population. This ageing, however, has been uneven across the globe and risks remain, said Goldstone.
“Ninety percent of all children under the age of 15 in the world today are growing up outside of North America, Europe, and the wealthy countries of East Asia,” he said, and in four or five decades time, “90 percent of the workforce of the world will be workers that have grown up outside of the rich countries.” It is this population’s “future productivity [that] will go far to determining whether quality of life gets better or worse.”
Demography and State Fragility
States across sub-Saharan Africa, South Asia, and the Middle East that perform poorly in indexes of state fragility also tend to have the youngest populations. “This could be just an unhappy coincidence,” said Goldstone, “but I don’t think that’s what’s going on. I think what we’re seeing is a kind of virtuous and vicious circle.”
“Where government is weak, ineffective, doesn’t provide education, doesn’t provide security, it’s advantageous both for individuals and for groups to have larger families,” he said. “However, as population grows, it’s more difficult for the government to provide adequate education and security for the larger, more youthful population.”
“On the other hand, if you can get on the track for a stronger, more legitimate government – a government that’s able to provide education, provide security of property, [and] encourage investment…fertility tends to drop quickly.” “This in turn re-enforces the ability of governments to direct resources to education and economic growth,” said Goldstone.
Critical Role of Governance
“Mobilization for political conflict draws heavily on youthful populations,” said Goldstone. As research by Henrik Urdal has shown, a bulge in the population of youth does appear to increase the risk of conflict. However, this relationship is strongly mediated by regime type. While strong democracies and autocracies are considered relatively stable, there is a “risk zone” in between, where instability is more likely.
“We live in a world where the countries with weak, fragile governments [are] about a third of the global population. But in another 30 years, if things remain as they are in terms of governance, you’re looking at closer to half the world’s population living in those more difficult circumstances,” he said.
“If the democracy is not well established, if rule of law is not well regulated, than people don’t necessary trust the outcome of peaceful electoral competition,” said Goldstone. “If people don’t like the outcome of an election, or they feel they’re being excluded, or things are one sided, they may mobilize.” This lack of political trust can result in instability and violence such as the recent protests by Thailand’s “red shirts.”
Although many Latin American and Asian states are heading towards “voluntary reduced fertility, strong economic growth, and stronger and more stable governments,” a real risk remains, he asserted. Africa, for instance, is “liable to gain a billion out of the next two billion in global population growth.”
Challenges for the Future
“For me, there are two big challenges posed by global demography,” opined Goldstone.
First, “given that 90 percent of today’s youth are in developing nations, providing them with opportunities to become productive adults through education, stable environment, [and] socialization is crucial.”
And second, in order to deliver those services, “strengthening governance in the countries where those youth live, in order for those education, security, and social services to be provided,” is absolutely necessary for economic development and reducing political instability.
While incidences of conflict have declined, the effects of those intractable conflicts that remain – in particular the sharp increase in the number of refugees and displaced populations uprooted by conflict – are solid arguments for continuing to address this risk.
