In a commencement speech at the U.S. Coast Guard Academy today, President Obama said “climate change constitutes a serious threat to global security, an immediate risk to our national security, and, make no mistake, it will impact how our military defends our country.”

2015 is a major test for the international system. The Sustainable Development Goals are expected to be adopted in New York in September and expectations for the UN Climate Summit in Paris are higher than perhaps any other time. “It is a critical year,” said Alan Hecht, director for sustainable development for the U.S. Environmental Protection Agency, “but our challenge is years of sustainable development. How do we take actions today, how do we prepare for the future in such a way that we will achieve a more sustainable outcome?” [Video Below]

In 2003, the United Nations General Assembly declared 2005 to 2015 to be the decade of “water for life” as a way to encourage countries to reach their water-related targets under the Millennium Development Goals. In summing up the last 10 years, it was noted that water cooperation had been promoted widely, featuring at international fora and in government initiatives and development agendas. Water cooperation is described as having the potential to enable peace and sustainable development. However, just as focusing on “water wars”  might undermine the everyday challenges of securing safe and adequate supplies of water, focusing only on “more cooperation” may well simplify the problem at hand.

In high-income countries, as many as 10 to 15 percent of women experience depression, anxiety, or other non-psychotic mental health challenges during pregnancy or the year after giving birth. In developing countries, the chances rise to 16 percent of pregnant women and 20 percent of post-natal women, according to Jane Fisher, professor of women’s health at Monash University in Melbourne, Australia. [Video Below]

From smoggy skies to rancid rivers and staggering slums, environmental challenges loom large for Asia. While much has been said about the role of government and NGOs in achieving a sustainable future, Mark Clifford, executive director of the Asia Business Council, believes companies are an indispensable but often overlooked part of the solution.

Among the few bright spots in the 2015 Freedom in the World Report, the brightest may be Tunisia, which for the first time was assessed as “free” – Freedom House’s highest “freedom status” and for many political scientists the definitive indication of a liberal democracy. Tunisia is the only North African state to have been assessed as free since Freedom House began its worldwide assessment of political rights and civil liberties in 1972, and only the second Arab-majority state since Lebanon was rated free from 1974 to 1976.

Sub-Saharan Africa is often characterized as an outlier in terms of population dynamics and reproductive health. While women are having fewer children around the world, even prompting some places to begin worrying about aging populations, the demographic transition is proceeding more slowly in Africa. Fertility rates in North and Southern Africa have declined to around three children per woman, but the three other sub-regions of the continent – East, Central, and West Africa – retain much higher fertility, between five and six children per woman. Whether, and how quickly, fertility rates decline in these regions over the next few decades will in large part determine the peak of world population. These regions’ demographic trajectories also have important implications for health, governance, food security, economic development, land use, climate vulnerability, and even security.

India occupies a precarious position in the global climate change order. It trails only China, the United States, and the European Union in total emissions, but per capita emissions are far lower. India’s Prime Minister Narendra Modi won the 2014 elections on a strong pro-development platform and continues to wave this flag at all levels, making energy security a major priority and pledging to expand the country’s coal mining industry. But he also insists he will work with the international community on mitigating climate change. During a recent visit to France, Germany, and Canada, he declared, “India will set the agenda for the upcoming Conference of Parties” in Paris this fall.
