Today approximately 44 percent of the world’s 7.2 billion people are under 24 years old – and 26 percent are under 14. Of those 7.2 billion people, a staggering 82 percent live in less developed regions of the world – primarily sub-Saharan Africa and Asia. Currently, the global median age is 29.2 years old, a sharp contrast to Europe, for example, where the median age is 41.

The disastrous flooding in the Himalayan state of Uttarakhand this summer, which claimed more than 6,000 lives, was the outcome of a changing climate and poorly planned development. It was also another case in point of the increasing importance of environmental security in India – especially for the military.

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.

Fire needs oxygen to burn. When a fire starts inside a building, the floors, ceilings, walls, doors, and windows can constrict the flow of air. Breaking in to fight the fire thus carries the risk of opening a new airway.

On May 11, Pakistan’s Election Day, approximately 60 percent of eligible voters went to the polls. This figure far exceeded the 44 percent who turned out for Pakistan’s previous election in 2008.

Water is the foundation of human society and will become even more critical as population growth, development, and climate change put pressure on already-shrinking water resources in the years ahead. But will this scarcity fuel conflict between countries with shared waters, as some have predicted, or will it create more impetus for cooperation?
