The demographic dividend – the idea that a decline from high to low rates of population growth can lead to dramatic economic gains – has become something of a buzzword in development circles. Sub-Saharan Africa holds the single largest block of remaining high fertility countries and while headlines tend towards the dramatic about demographic shifts there, less column space has been devoted to examining the underlying issues causing these shifts or the other changes that will be necessary for countries to benefit from them.

In a recent post on the new United Nations population projections, I discussed the risk in assuming that countries in sub-Saharan Africa will progress through the demographic transition at a pace similar to other regions. Making this assumption is questionable because fertility decline in Africa has generally proceeded more slowly than in other parts of the world, with several cases of “stalls” and even small fertility increases over time.

Water, energy, and food – this “nexus” of interrelated resource issues continues to garner attention from analysts, policymakers, and the media. Over the next four decades global population is projected to increase to about 9.6 billion and, worldwide, demand for water is projected to increase 55 percent; energy, 80 percent; and food, 60 percent. In a new video about the first of a series of workshops on this nexus, the International Union for Conservation on Nature and the International Water Association explain how they are working to bring together private and public sector water infrastructure experts from across Africa and the world to build partnerships and create some consensus on a “nexus-based approach” to managing scarce resources.

Cambodia to grow by nearly one-third by 2050; Kenya to more than double; Mali to swell to three times its current size. These were the population projections available when Feed the Future, President Obama’s global hunger and food security initiative, was beginning implementation in 19 focus countries around the globe in 2010.

According to the UN, the planet has warmed faster since the turn of the century than any other period on record. Sea-level rise has also increased pace to 0.12 inches a year – almost double the rate observed during the 20^th century. This “unprecedented” rate of climate change is expected to disproportionally impact developing countries, whose socio-economic, political, and physical landscapes make them particularly vulnerable to the effects. The GAIN Index, an interactive mapping tool recently acquired by the University of Notre Dame, can help policymakers prepare for these changes by comparing the climate change vulnerability and readiness of countries around the world.

According to the UN Population Fund, more than 140 million girls will become child brides between 2011 and 2020 – an estimated 14.2 million young girls marrying too young every year or 39,000 daily. The majority of these girls do not receive access to education or reproductive health services. [Video Below]

“The places in the world where the environment is most fragile, women’s health is most fragile,” said Leila Darabi, director of global communications for the Planned Parenthood Federation of America, at the Wilson Center. “The negative impacts on the environment tend to affect women the most. Women are the people who are planting kitchen gardens, women are traditional healers, and so they often feel the impact first when those things are degraded.”

Despite increases in the availability of maternal health care across Nigeria, maternal mortality rates remain high, averaging 630 per 100,000 live births in 2010, compared to the world average of 210. “This is data we are not proud of,” said Philippa Momah, board director of Nigeria’s White Ribbon Alliance, at the Wilson Center. “We believe that one of the issues is the way health care providers treat our women. This may be causing a 20 percent drop-out rate in the health care system.” [Video Below]
