On a warm January afternoon, Tesema Merga, a village elder in Endibir, Ethiopia, surveyed the latest improvements to the long dirt road just outside his house. Eventually this road will be paved, which will bring significant changes to the community.

“We don’t know the reason for the death of fish in downstream villages,” Hamberton Nongtdu, a mine owner from the northeastern Indian state of Meghalaya, told me.

For years, the Chepang people have lived off the land in Nepal’s forested central foothills. Communities cleared trees to start small subsistence farms, harvested the surrounding area for firewood, and eventually moved on after the wood, soil, and water were depleted.

As our ferry slowly made its way across the Pangani River along the northern coast of Tanzania, I sat next to a woman whose child held her hand tightly. The boy and I exchanged smiles, but we mainly admired the view. The late morning sun was behind us as the royal blue river met the cloudless sky.

“I am now serving as an example to other women in the community because I am not having any more children. I have received training in sustainable agricultural practices, I’m generating income, and I’m educating others,” said Berhane Ferkade, an Ethiopian farmer, to Population Action International’s Roger-Mark De Souza earlier this year. The 39-year-old mother of 11 become one of the community’s model farmers after working with LEM Ethiopia – a local population, health, and environment (PHE) development organization.

Severely eroded and deforested, Ethiopia’s land is increasingly turning to desert, due to the country’s high population growth, unsustainable land use, and lack of land ownership. Featuring footage from my trip to Ethiopia last year, this video looks at the efforts of two projects to combat these devastating trends by meeting the country’s complex challenges with integrated solutions.

Ethiopia’s population is estimated at 85 million. Since 1900, the country has grown by nearly 74 million people, and the United Nations predicts this rapid growth will continue, reaching nearly 120 million people by 2025.

It was a bit of a shock to hear population-environment connections being discussed on television, including the Most Trusted Name in News (aka Jon Stewart’s Daily Show), as well as CNN’s Amanpour, late last month.

“It is not enough to say that Ethiopia is vulnerable,” says Joshua Busby, an assistant professor at the LBJ School of Public Affairs at the University of Texas at Austin. Also necessary is “which parts of Ethiopia are vulnerable and why.” Busby is part of the Department of Defense-funded Climate Change and African Political Stability (CCAPS) project. Part of the Minerva Research Initiative, CCAPS is a multi-year, multi-institution effort to diagnose and assess the causal connections between climate change and security consequences.
