In recent years, the urgency of climate action has brought fresh attention to the critical minerals sector. Growing renewable energy investments are driving up demand for resources like lithium, cobalt, and copper, which form the mineral backbone of green technologies. But there are substantial concerns to navigate when it comes to sourcing green energy minerals.

Secretary of State Anthony J. Blinken recently reaffirmed the Democratic Republic of Congo (DRC)—a nation located in Africa’s heart—as a “geostrategic player and critical partner” for the United States. It is a country that features prominently in climate change discussions, not only because of  its vast natural resources (including mineral wealth estimated to be the largest in the world, as well as possession of a forest cover second only to the Amazon Basin), but especially due to its cobalt reserves.

Climate security is an essential conceptual framework to understand the global interplay of biophysical and socioeconomic forces that threaten our planet. Indeed, it is so important that new currents of science, politics, and advocacy make refining definitions a necessity.

The negative impacts on global food security wrought by Russia’s war in Ukraine are obvious. But recent news that Russia currently occupies more than one fifth of Ukrainian farmland, draws attention to another dimension of this politically-induced food and agricultural crisis: land itself. Of course, territory has long been an object of conflict and warfare. But agricultural land—in particular—is also a key, though understated, dimension of the geopolitical ambitions undergirding Russian activity at home and abroad.

Ever since the CNA’s Military Advisory Board—composed of former U.S. military personnel—named climate change as a “threat multiplier” in a 2007 report, the term has gained widespread currency both in environmental and national security circles. It also has propelled the need to assess and address climate-related security risks higher up overall policy agendas.

Supply chain considerations in today’s globalized economy have expanded beyond minimizing costs. As Duncan Wood, Vice President for Strategy and New Initiatives and Senior Advisor to the Mexico Institute at the Wilson Center, noted at a recent panel hosted by the Environmental Change & Security Program as part of the Transatlantic Climate Bridge conference, issues ranging from environmental, social, and corporate governance (ESG) to national security and geopolitics, have transformed critical mineral supply chains into something that is now “inherently political.”
