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.

This year, Texas-based Anadarko and Italian partner ENI are due to make the final investment decision on whether to construct one of the largest liquefied natural gas facilities in the world in Mozambique. The complex would allow them to tap into deep off-shore gas fields that could rival Australia and Qatar as the largest liquefied natural gas reserves in the world.

“We are at a critical juncture in human history, which could lead to widely contrasting futures,” writes the chairman of the National Intelligence Council (NIC) Christopher Kojm in the council’s latest forward-looking quadrennial report, Global Trends 2030: Alternative Worlds, released yesterday.

This year, principal author Mathew Burrows and his colleagues focus on a series of plausible global scenarios for the next 20 years and the trends or disruptions that may influence which play out. Among the most important factors in these projections are demography and the environment.

Access to safe water is often taken for granted in developed countries. But last week at the 22^nd annual conference of the Society of Environmental Journalists, panelists argued that the impact of dirty water on women’s health is an important but neglected story, not only in developing countries like Nigeria, but also in the United States.

The poorest households gain the least when countries reap the demographic dividend, according to a preliminary draft of a new study by four Harvard School of Public Health researchers. In “Microeconomic Foundations of the Demographic Dividend,” authors David Bloom, David Canning, Günther Fink, and Jocelyn Finlay write that 18 years of Demographic Health Surveys (DHSs) from 60 developing countries show that while declining fertility rates and dependency ratios can lead to rising incomes on a nationwide level, sub-nationally those trends occur unevenly and mostly benefit wealthier households. Poorer households, meanwhile, are likelier to see slower fertility declines, delaying the economic gains that can result from demographic transitions, and increasing inequality. Importantly, the authors emphasize that the study reflects “the early stages of the demographic transition”; long-term economic effects of fertility decline, they write, “remain ambiguous.”

It’s not often that a change in accounting rules could reduce the probability of war. But that’s exactly what happened at the U.S. Securities and Exchange Commission (SEC) last month.

Over the past few months, the Sahel drought has sparked attention of news media and concerned citizens around the world. Throughout this media blitz, I have been struck by the sharp contrast between this coverage and how the devastating effects of malnutrition are usually portrayed. Malnutrition is often overlooked in favor of more “newsworthy” diseases, and it takes a crisis to focus our attention on this public health issue. Yet an emergency such as this drought – affecting more than 18 million people, including nearly 2 million children – is difficult to ignore.

The number of urban slum dwellers worldwide is staggering. According to UN-Habitat, 827.6 million people live in slums around the world. Despite meeting a Millennium Development Goal to significantly improve the lives of at least 100 million slum dwellers by 2020, the total number of people living in these areas still increased by 55 million between 2000 and 2010. By 2020, the world slum population is projected to reach 889 million. With the majority of people now living in cities, urban priorities are synonymous with human security and environmental sustainability and must be accounted for in the global development agenda.
