“We did something very special for the community and the resources these farmers live with. We sat down with local leaders and promised to stop spending so much time caring about the elephants, and instead create a company that will try to address community needs,” said Dale Lewis in an interview at the Wilson Center. “The deal was they had to put down their snares and guns.”

Today, the Sahara Desert is a vast, nearly lifeless expanse of sand and rock. But ancient cave paintings tell of a time when it was fertile grassland and bands of human hunters chased aurochs and antelope.

Environmental security and international development aren’t typical movie-going fare, but at the 2013 DC Environmental Film Festival, ECSP premiered two short documentaries with unique environmental stories: Healthy People, Healthy Environment: Integrated Development in Tanzania shows how improving health services and environmental conservation can empower coastal communities in Africa; and Transcending Boundaries: Perspectives from the Central Albertine Rift Transfrontier Protected Area Network explores the opportunities for “peace parks” along the shared borders of Uganda, Rwanda, and the Democratic Republic of Congo.

What does family planning have to do with Earth Day? More than you might think. Family planning gives women and families the tools they need to decide whether and when to have children – and that, quite literally, can mean the world.

A well-known Chinese proverb describing the relationship between the central government in Beijing and its people says, “Heaven is high and the emperor is far away” (天高皇帝远, tian gao, huang di yuan). It’s not too far of a stretch to apply the same proverb to the current state of China’s environment sector, where relatively strong pollution control laws are poorly enforced on the ground.

While it can be convenient to think of human health and the environment as unrelated silos, they are in fact closely related. The United Nations Environment Program (UNEP) recently released a report underscoring this point especially for Africa, where large numbers of people are directly reliant on natural resources for their livelihoods.

Fifty years after independence, Uganda has one of the highest population growth rates in the world at 3.3 percent – a rate which puts the country on track to nearly double in population over the next two decades. More than 50 percent of the population is under the age of 18. This large youth cohort will ensure that the country continues to grow for decades to come, even if couples choose – and are able – to have smaller families. And according to the State of Uganda Population Report 2011, “with more than one million people added to the population every year, the quality of [health] service delivery will suffer.”

The future is urban – but is it sustainable?

For decades – centuries, really – warnings have been issued: The burgeoning human population will outgrow the planet’s capacity to sustain us. The formula seems simple. More people equals fewer resources and greater environmental damage.
