Isabel dos Santos, the daughter of Angolan President José Eduardo dos Santos and the richest woman in Africa, owes her wealth to the oil industry. Delfina Fernandes, a woman living in abject poverty in the village of Kibanga, uses gasoline as an anesthetic to dull the sheering pain of her rotting teeth.

Earlier this month, the United Nations released a final report on the Millennium Development Goals (MDGs), the framework that has guided global development efforts for the last 15 years. The document examines each of the eight MDGs and finds that “despite many successes, the poorest and most vulnerable people are being left behind.” As one of the first global poverty reduction movements nears its end, the report calls for better data collection practices to create a post-2015 development agenda that can overcome the MDG’s shortcomings.

In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.

Since President Lyndon B. Johnson created the USAID population program in 1965, it has evolved in tandem with the global discourse on population and demography. “The agency’s family planning program is as relevant today as it ever was, and is necessary,” said Jennifer Adams, deputy assistant administrator of the U.S. Agency of International Development’s Bureau for Global Health. The bureau houses the Office of Population and Reproductive Health, which implements U.S. development and relief efforts to expand access to modern contraceptives, fight HIV/AIDS, reduce unsafe abortions, and protect the health of women and children.

Earth’s thin upper-crust of soil is kept in balance by a complex carbon and nutrient cycle that is increasingly threatened by human exploitation and climate change, according to a review in Science. The chemicals trapped in topsoil and subsoil are crucial to plant growth, but are being depleted at rates much higher than they are being replenished, writes Ronald Amundson et al. For instance in the central United States, estimated soil erosion rates exceed production rates by 10 times.

Pope Francis sparked worldwide discussion and jubilation among many green advocates after releasing Laudato Si, the first Papal encyclical to focus directly on the environment. The pontiff touched on everything from pollution and sustainable development, to anthropogenic climate change and water security in his 180-page missive.

The landscape of the northeastern Indian state of Meghalaya is rapidly changing. What was once a predominately agricultural economy has shifted to coal mining with significant consequences for people and the environment. “Once you extract coal from the land, it’s really hard to go back to an agricultural economy,” says ECSP’s Sean Peoples in an interview with Wilson Center NOW, about the Global Choke Point film, Broken Landscape.
