“Over the past several months, extreme weather and climate events seemed to have become the norm rather than the exception,” writes Kelly Levin for the World Resources Institute (WRI). Indeed, records have been broken around the world as countries experience unprecedented heat, drought, flooding, or other types of severe weather. And people are starting to take notice. A number of recent stories try to make sense of this wild weather and what, if anything, it has to do with climate change.

People are still talking about this summer’s London Summit on Family Planning, which was hosted by the Bill and Melinda Gates Foundation and the UK’s Department of International Development (DIFD) on July 11. On Monday here at the Wilson Center, the Environmental Change and Security Program featured representatives from USAID, DFID, and Gates Foundation for a standing-room only panel discussion of the landmark event.

The elderly are a crucial link in the chain that binds generations and sustains civilized society. Today, however, older people are largely considered to be out of touch with the modern, technology-driven world, and incapable of paying their own way. But much evidence shows otherwise: If aging were framed as an economic opportunity, the growing number of older people worldwide could become modernity’s gift, rather than society’s burden.

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.”

The United Nations biannual population projections are some of the most (if not the most) widely used numbers in demography. Researchers and policymakers alike rely on the figures to plan for present and future challenges. But few consider the story behind the statistics. Where does the data come from? The United Nations Population Fund (UNFPA) recently released a short documentary on conducting censuses in challenging environments, with a spotlight on Indonesia, Chad, the Palestinian Territories, Belarus, and Bolivia.

Twenty-five years have passed since the Brundtland Commission first brought sustainable development to international prominence. Today, the United Nations appears on track to replace the soon-to-expire Millennium Development Goals with “Sustainable Development Goals,” marking the extent to which the international community has embraced the concept. And yet, in spite of its prominence, a specific and measureable definition of sustainability remains lacking.

For many people, Timbuktu has long represented the essence of remoteness: a mythical, faraway place located on the boundaries of our collective consciousness. But like many of the myths associated with colonialism, the reality is very different.

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.
