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.

Around the world, urbanization and climate change are transforming societies and environments, and the stakes could not be higher for the poor and marginalized. The 2015 UN climate conference in Paris (COP-21) highlighted the need for coordinated action to address the profound injustice of the world’s most disadvantaged people bearing the greatest costs of climate impacts. Among those at the COP were mayors from around the world advocating for the important role of cities in these efforts.

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]

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.

The renewable energy sector has reached a critical inflection point where costs are competitive with fossil fuels and investment is ramping up in a big way, said more than a dozen experts at a day-long conference co-hosted by ECSP and the U.S. Agency for International Development’s Office of Global Climate Change on October 27.

The Global Maternal Newborn Health Conference, held in Mexico City from October 18-21, will provide a forum to identify, understand, and respond to the most urgent health needs of mothers and newborns. The hope is that it will accelerate momentum for maternal and newborn health in the newly adopted Sustainable Development Goals and put us on a track to end all preventable maternal and newborn deaths.

When war breaks out, what happens to the weather forecast? Violent conflict disrupts many essential services in developing countries and one of the most overlooked is meteorology, which has surprisingly big consequences for farmers, policymakers, and the aid workers who are there to help.

In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.
