In 2013 the United Nations Population Division revised its population projections to show that population could grow even faster than previously anticipated, especially in Africa. Planning ahead for feeding a hot, hungry, teeming planet is both a numbers game and social venture. Calories, climate change, and acres of land are some of the factors on one side of the equation. The 7 billion people in the world, projected to grow to 9.6 billion by 2050, are on the other.

Years ago, when I was a diplomatic correspondent at a large national magazine, if I encountered what I thought of as “science stuff,” I sent it to the science desk. I was busy covering foreign policy, wars, and ethnic and religious conflicts – not science. It was only when I took a new job focused on educating the U.S. media on a wide range of international issues that I began to discover the rich world I had overlooked, and see new links and connections.

The global water wars are almost upon us!

At least that’s how it seems to many. The signs are troubling: Egypt and Ethiopia have recently increased their aggressive posture and rhetoric over the construction of the Great Ethiopian Renaissance Dam in the headwaters of the Blue Nile, Egypt’s major artery since antiquity. India continues to build new dams that are seen by its rival Pakistan as a threat to its “water interests” and thus its national security. Turkey, from its dominant position upstream, has been diverting the Tigris and Euphrates rivers and increasing water stress in the already-volatile states of Iraq and Syria.

Given growing awareness about environmental change and how it affects human life, it is perhaps not surprising there is also a growing audience for environmental filmmaking. At the 2014 Environmental Film Festival in the Nation’s Capital on March 25, the Wilson Center premiered ECSP’s latest documentary, Scaling the Mountain: Protecting Forests for Families in Nepal. Together with Heart of Iron, a recent film on mining in the Congo Basin, the event took viewers into some of the world’s most remote forests to see how their inhabitants are adapting to rapid changes in the natural resources on which they depend.

If current projections hold, Africa’s population will more than double in 40 years, putting more people at risk of food, water, health, and economic insecurity as the climate changes, as well as negating progress made in reducing carbon emissions per person. But what if it didn’t? [Video Below]

Imagine you’re a woman living in Pakistan who would like to decide if and when to have children. You’re going to school, or you’ve got a job, or you’ve had a child and simply want some space before your next pregnancy. How easy will it be for you to get your needs met?
