On day three of the 2013 Global Maternal Health Conference here in Arusha, Tanzania, I was joined by the Global Health Initiative’s partners to present the results of the Wilson Center’s four-year-old Advancing Dialogue on Maternal Health Series. This series is unique in its convening power, helping to bring together experts and policymakers from around the world to collaborate on a shared goal: healthier mothers and children.

Carbon offsets have fallen in and out of favor since they were established with the Kyoto Protocol in 1997. Critics say they allow wealthy organizations to placate consumers and claim their products are “green” without making any real, lasting changes. But, if the scheme works properly, some action is supposed to be taken somewhere, so what is it like at one of these credit-producing organizations?

The fault line between nomadic pastoralists and sedentary agriculturalists in sub-Saharan Africa has emerged as one of the most dominant stories of climate-related conflict. But according to Edna Wangui, a professor at Ohio University who studies communities in Kenya and Tanzania, pastoralism is different from many people’s perceptions.

“When I embarked on this series, I approached it as an environmental reporter: What does a growing number of us and growing consumption mean for our planet?” said Los Angeles Times reporter Ken Weiss at the Wilson Center on October 9. Weiss, along with photographer Rick Loomis, recently completed a five-part series and multimedia presentation on global population that was the culmination of a year of research and travel through more than six countries. [Video Below]

“Resilience is the capacity of individuals and institutions to cope and adapt in the stress of chronic violence in ways that allow them room for maneuver and hope for the future,” said Diane Davis, Harvard professor of urbanism and development, in an interview at the Wilson Center.

Earlier this month, there was a flurry of stories about brutal mass killings in clashes between the Pokomo and Orma communities over water and land in southeast Kenya’s Tana River County. The Kenyan media reported that about 30 people, including eight security personnel, had been killed and scores wounded, and reports on the death toll since last month are more than 100.

In 1979, Egyptian President Anwar Sadat famously said that “the only matter that could take Egypt to war again is water.” Sadat’s message was clear: the Nile is a matter of national security for Egypt.

Indeed, Egypt relies on the Nile for 95 percent of its water. But it is not the only state with an interest in the world’s longest river. There are 11 states in the Nile River basin, which stretches from Africa’s Great Lakes region – Tanzania, Uganda, Kenya, Rwanda, Burundi, and the Democratic Republic of the Congo – to the Ethiopian and Eritrean highlands through South Sudan, Sudan, and Egypt to the Mediterranean Sea.

The number of urban slum dwellers worldwide is staggering. According to UN-Habitat, 827.6 million people live in slums around the world. Despite meeting a Millennium Development Goal to significantly improve the lives of at least 100 million slum dwellers by 2020, the total number of people living in these areas still increased by 55 million between 2000 and 2010. By 2020, the world slum population is projected to reach 889 million. With the majority of people now living in cities, urban priorities are synonymous with human security and environmental sustainability and must be accounted for in the global development agenda.
