Inspired by the success of East Asian economies, the demographic dividend framework is taking off in sub-Saharan Africa, where many are yearning for workable solutions to the region’s ongoing development challenges.

The deadly West African Ebola epidemic has largely faded from headlines, replaced by mounting concern over conflict in the Middle East, terrorism, and refugees streaming into Europe. But while Guinea and Sierra Leone were declared free of the disease in November, Monrovia saw three new cases two weeks later. At least 149 individuals who came into contact with the infected have been identified thus far, according to the World Health Organization (WHO).

Global attention is understandably focused on Syrian refugees, but the migration crisis in Europe is part of a bigger trend that climate and social scientists have been warning about for years.

In his speech on climate change and national security on November 10, Secretary of State John Kerry said climate change is already a “threat multiplier,” and that worse is to be expected if climate change continues unchecked. But the relationship between the environment and violent conflict is complex and often indirect. Researchers have been wrangling for years over the role that global environmental change plays in fueling conflict and state fragility.

When Colombia is in the news, it’s not necessarily for the reasons we Colombians would like. We have lived through 50 years of violent conflict. Peace is a very abstract idea to most of us. Despite this we are still some of the happiest people on Earth.

As most of the world’s governments are puzzling out what they can offer to combat global climate change, a sensitive but critical aspect of the problem is coming into clearer focus: population. The word appears 20 times in a new 66-page synthesis of country pledges to cut greenhouse-gas emissions by the UN Framework Convention on Climate Change’s Secretariat. And those are the mentions of population in the context of size or growth, not the word’s more frequent use as a synonym for “people.”

The world has entered a new energy era. Last year, for the first time in four decades, the global economy grew without an increase in CO2 emissions, according to the Renewable Energy Policy Network for the 21^st Century.

From earthquakes to floods, when natural disasters strike, the military is often called on to bolster civilian responses. Policymakers throughout Latin America in particular are increasingly relying on the armed forces for emergency assistance.
