Water resources, energy, and land use are so mutually dependent that climate-related disruptions to any one of them could lead to economically devastating ripple effects – especially as a growing population puts increasing strains on all three. That’s one conclusion of a recent report issued by a federal advisory committee charged with assessing how climate change has already affected the U.S., and what the future holds.

2012 witnessed a remarkable number and extremity of environmental conditions, from Hurricane Sandy and the U.S. drought to wildfires in Siberia and drought-driven blackouts in India. Arctic sea ice melted to its furthest extent in recent history. The energy landscape continued to change as well, from the launch of the U.S. Navy’s Great Green Fleet to the first liquefied natural gas shipments across the Arctic. As President Obama clearly stated in his second inaugural address, climate change is heightening both our risks and the need to respond, but tying together all of these issues is a highly complex endeavor.

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.

In the tiny tortillerias of this city, people complain ceaselessly about the high price of corn. Just three years ago, one quetzal – about 15 cents – bought eight tortillas; today it buys only four. And eggs have tripled in price because chickens eat corn feed.

1.8 million food producers using improved technologies or management practices. Nearly 9 million children reached through nutrition programs. 2.4 million hectares under improved technologies or management practices. New mechanisms for donor coordination. A forward-looking agricultural research agenda. Innovative private-sector partnerships to support smallholder farmers. These are among the successes reported for the first three years of Feed the Future, the U.S. government’s new global hunger and food security initiative.

The future is urban – but is it sustainable?

For decades – centuries, really – warnings have been issued: The burgeoning human population will outgrow the planet’s capacity to sustain us. The formula seems simple. More people equals fewer resources and greater environmental damage.

Every year the United Nations convenes diplomats from more than 190 nations to negotiate a climate change treaty, and in many years negotiators go home with little more than the promise of another annual meeting.
