A new report from the International Institute for Environment and Development seeks to understand why Uganda’s Bwindi Impenetrable National Park continues to be exploited despite park officials’ implementation of “integrated conservation and development” (ICD) efforts. The study finds that local people’s perceptions of the benefits of the integrated conservation and development vary depending on five primary factors: age, level of education, homestead distance to the national park, quality of life, and wealth.

We started the last top 10 post tracking the dramatic battle over Iraq’s Mosul Dam and the most popular of August took a closer look. Cameron Harrington and I explain that this isn’t the first time water has played a major role in the fighting, while also exploring ways it could be a peacemaker.

Nearly 1 billion people lack reliable access to clean drinking water today. A report by the Water Resources Group projects that by 2030 annual global freshwater needs will reach 6.9 trillion cubic meters – 64 percent more than the existing accessible, reliable, and sustainable supply. This forecast, while alarming, likely understates the magnitude of tomorrow’s water challenge, as it does not account for the impacts of climate change.

In 2012, as part of the Every Women Every Child movement, 13 vital health commodities were identified by a UN panel that could save the lives of more than 6 million women and children over the course of five years. There are often significant cultural and behavioral barriers to these commodities reaching people in low- and middle-income countries, but physical logistics is also a major problem.

In 1986, global nuclear weapons stockpiles peaked at nearly 70,000 warheads. By the beginning of 2013, there were just over 17,000, with only 4,400 kept operational. This dramatic reduction was the fruit of a negotiation process that began in the late 1940s. In spite of incredible tensions between the United States and the Soviet Union, negotiators were able to make progress once they focused on building trust with small, pragmatic steps, rather than starting with the complete elimination of all weapons. [Video Below]
