A little over a decade ago when I first became interested in the subject of environmental security, it took me ages to understand what I have since been eager to stress: environmental security is not a concept but rather a debate.

Amid the growing number of reports warning that climate change could threaten national security, another potentially dangerous – but counterintuitive – dimension has been largely ignored. Could efforts to reduce our carbon footprint and lower our vulnerability to climate change inadvertently exacerbate existing conflicts – or create new ones?

Stretching across northern Africa, the Sahel is a semi-arid region of more than a million square miles covering parts of nine countries. It is home to one of the world’s most punishing climates; vast expanses of uncharted and unmonitored desert; busy migration corridors that host human, drug, and arms trafficking; governments that are often ineffective and corrupt; and crushing poverty. It is not surprising then that the area has experienced a long history of unrest, marked by frequent military clashes, overthrown governments, and insurgency.

One year ago, the United States government froze all property of the Central Bank of Iran and other Iranian financial institutions within the United States. The move was part of a broader effort to compel the Islamic Republic to give up its alleged nuclear weapons program. How is it working out?

Friction between Japan and China in the East China Sea has escalated this year to the point where jets on both sides have been scrambled and Chinese military vessels have locked their fire control radar onto their Japanese counterparts multiple times. The source of this tension is the Senkaku (as they are known in Japan) or Diaoyu (if you’re in China) Islands – specifically, who owns them.

ECSP Senior Advisor and Ohio University Professor Geoff Dabelko appeared on Marketplace yesterday to comment on Defense Secretary Nominee Chuck Hagel’s confirmation hearings and whether the Pentagon’s pursuit of renewable energy and other “green” technologies might enter the discussion.

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.
