Today, Africa has the world’s highest fertility rates. On average, women in sub-Saharan Africa have about five children over their reproductive lifetime, compared to a global average of 2.5 children. Research shows that the “demographic transition,” the name for the change from high death and fertility rates to lower death and eventually lower fertility rates, has proceeded differently here from other regions in the developing world.

According to political demographers, who study the relationship between population dynamics and politics, two characteristics when observed together provide a rather good indication that a state is about to shed its authoritarian regime, rise to a high level of democracy, and stay there. Myanmar has both.

Zika is a global health challenge. Since its outbreak in Brazil last May, the virus has spread to more than 30 countries and territories and ignited global discourse about family planning, vaccine development, reproductive rights, contraceptive security, and even gender norms.

On February 1, the World Health Organization declared the spread of the Zika virus a public health emergency.

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.
