As a young and promising marine biologist, Camilo Mora led a team of 55 scientists assessing the rapid decline of fish on the world’s coral reefs. It was a global enterprise with broad implications. Hundreds of millions of people rely on reef fish for their primary source of animal protein. Healthy reefs protect coastal communities from devastating storms and provide a multitude of livelihoods, including jobs in the fast-growing tourism industry.

Ask Agnes Namukasa about sustainably managing fisheries in Kachanga, the lakeshore landing site she calls home in Uganda’s Masaka District, and you will soon learn about toilets. From her perspective, community members won’t address conflict between government enforcers and fishers, competition among neighboring villages, or pollution threatening aquatic ecosystems until they can first organize to address their most pressing daily needs. And in Kachanga, where chronic childhood diarrhea and a host of other illnesses stem from poor sanitation, those essentials include public latrines.

The Outcast Majority: War, Development, and Youth in Africa is born of a growing sense that the status quo won’t work, in Africa or elsewhere. Enormous youth cohorts, containing many who feel socially sidelined, call for a response that, at best, is sporadically seen.

In the course of development, most countries undergo a demographic transition. Health conditions improve and mortality rates decline, causing rapid population growth and a relatively high proportion of young people. Over time, if fertility declines, as it has in most places, growth slows and there is a period when the proportion of very young “dependents” shrinks in comparison to the working age population. This moment represents an opportunity for a “demographic dividend” – an economic boom as a comparatively large cohort of the total population moves through their most economically productive years. [Video Below]

Last month, for the first time, 195 countries formally agreed to take steps to slow and eventually reduce carbon emissions. “This is potentially one of the most important things that’s ever been done for your children, your grandchildren…and their welfare in the future,” said Andrew Light, professor of public philosophy at George Mason University. [Video Below]

Who walks away from fertile agricultural land available to lease for as little as $1 per year per hectare? Recent reports indicate international investors are doing just that across sub-Saharan Africa.

Aissata M.B. Camara grew up in an educated, upper income household in Guinea, West Africa. One morning, she woke up to singing outside her window and knew they were coming. Many in her community thought that she was unclean and would grow up to be promiscuous if she wasn’t cut. She would be unmarriageable. While her family and community members held her down, she realized, “my body no longer belonged to me.” [Video Below]

The sexual and reproductive health and rights of women and girls must be protected, even – especially – during “the toughest of times, in the hardest of places,” said Kate Gilmore, deputy executive director of the United Nations Population Fund (UNFPA), at the Wilson Center on December 3. [Video Below]
