Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

Dams can be a double-edged sword, said Aaron Salzberg, a Wilson Center Global Fellow, Director of the Water Institute at the University of North Carolina, and former Special Coordinator for Water Resources for the U.S. Department of State. He spoke in a recent episode of Wilson NOW about the Grand Ethiopian Renaissance Dam, which will become Africa’s largest hydroelectric dam, once it’s fully operational.

Trouble is brewing on the Nile. For years, use of the river was mainly about the needs of Egypt, by far the largest and most powerful riparian country in the basin. But since the Arab Spring of 2011, the situation has changed considerably. Egypt’s troubles over the last decade have weakened its ability to project power southward, while upper riparian states—Ethiopia in particular—have enjoyed a period of economic growth and relative stability, which has led them to look at the great river as an important national resource. Tensions have come to a head since Ethiopia announced the construction of the Grand Ethiopian Renaissance Dam (GERD), construction of which is now almost complete. Once full, the resulting reservoir will be larger than the whole of Greater London. Much of the water it holds would have previously reached Sudan and Egypt largely unhindered.

Is the world doomed to be ever-more tumultuous? For years, headlines have suggested that climate change causes or acts as a threat multiplier for violent conflicts. For example, climate change-influenced drought has been labeled a cause of the Syrian conflict and the war in Darfur. Natural hazard-related disasters (“disasters”) like earthquakes that are not related to climate change have also been connected to an increased risk of violent social conflict and political instability. The narratives are often that disasters displace people who then put pressure on already-strained resources and infrastructure in receiving areas, and that disaster-stricken people fight over limited resources in their struggle for survival.

Former Vice President Biden’s recent Foreign Affairs article on his proposed presidential policies hit on all major hot spots of U.S. interest globally but one, said Mike Sfraga, director of the Wilson Center’s Global Risk and Resilience Program and Polar Institute, in a recent episode of Wilson Center NOW.

“The Arctic should be a part of the foreign policy dynamic of the United States,” said Sfraga. Global politics, economics, security, and the environment connect in countless ways throughout the region, only some of which show up in headlines.

A special type of tree could facilitate peacebuilding in the Sahel. A stretch of semi-arid land south of the Sahara that runs from the Red Sea to the Atlantic Ocean through 10 countries (Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Algeria, Mauritania, and Senegal). But the western subregion covering the Lake Chad area (the intersection of Chad, Cameroon, Nigeria, and Niger) and Liptako-Gourma (the tri-border zone of Burkina Faso, Mali, and Niger) in the Sahel has been the scene of a growing humanitarian crisis. Armed groups are terrorizing local populations. Rampant insecurity has forced 1 million people to flee their homes. People have been cut off from their livelihoods. Food insecurity is worsening. Casualties continue to mount. And climate change will likely exacerbate conditions, forcing more people to compete for depleted forest resources and land. More food shortages and instability will surely follow.

Meaningful engagement with the social and conflict implications of climate change in Solomon Islands must be firmly grounded within local worldviews—within Solomon Islanders’ physical, economic, political, and social and spiritual worlds. As we note in a recent policy brief for the Toda Peace Institute, when addressing conflict challenges exacerbated or caused by climate change, approaches should be draw upon community understandings of what constitutes peace and justice.
