In 2014, we met with some of the technical leads of a major Chinese river basin authority in Beijing and asked them whether they were more worried about pollution or climate change impacts. Both, the engineers replied. Pollution affects us every day, they said, but changes in the climate erode our ability to supply drinking and irrigation water, manage floods, and generate electricity.

China must address its environmental and climate change challenges, such as reducing water pollution and building resilience to droughts, floods, and long-term climate shifts. But existing sources of finance have not met the growing demand for environmental projects.

Cape Town is running dry. But thanks to its sophisticated water management efforts, the city may ride out the crisis. However, other cities that lack these capacities are less likely to survive Day Zero. Especially in developing countries, where urban water services are often provided by informal or illegal actors, running out of water could have dangerous ripple effects for peace and security.

After pirates hijacked an Iranian fishing vessel last year near Bosasso, a major seaport in Puntland, Somalia, local authorities observed that the offending boat was casting nets without a license. While piracy has diminished since 2008-2012, when these waters became some of the most lawless in the world, a spate of incidents in 2017-8 has made it clear that the conditions that led to piracy—including incursions from foreign fishing boats—are still a major problem.

“Most fundamentally, we turned the ‘resource scarcity drives conflict’ argument on its head and asked, ‘Can environmental interdependence drive cooperation in ways that can be harnessed to build trust and contribute to conflict prevention and peacebuilding?’” said Geoff Dabelko, Associate Dean at Ohio University’s Voinovich School of Leadership and Public Affairs, about Environmental Peacemaking, which was one of the first books to investigate these questions. In the 15 years since he and Ken Conca, a professor at American University’s School of International Service, published their edited volume, the idea that shared environmental issues could be used to build peace has become a focus of innovative research, policy, and programs.

A recent article in Nature Climate Change has spurred a new chapter in the lively scholarly debate over the potential relationship between climate change and violent conflict. We agree with the article’s authors that there are several forms of sampling bias in this field, including how regions are selected for analysis. But simply addressing this sampling bias will not resolve many of the academic controversies that have raged since the mid-2000s. Our recently published study in International Studies Review examines the mechanisms connecting climate change or its consequences to violent conflict and concludes that to move this research agenda forward, researchers must pay deeper attention to the “nuts and bolts” that shape both climate-related conflicts and our understanding of them.

In 2017, four environmental activists were murdered every week on average—most of them in Latin America, and most of them targeted for protesting industries like logging or mining. These shocking numbers may finally start to taper off, if three new initiatives launched just this month are successful at protecting people’s right to a clean environment—and its defenders.

The Mississippi River Valley has been hit by droughts, floods, extreme heat, and tornadoes that resulted in damages totaling over $50 billion since 2011. From 2005 to 2017, that total eclipses $200 billion with each effected state incurring a minimum $5 billion in damages. One positive result in reaction to those natural disasters was the formation of the Mississippi River Cities & Towns Initiative (MRCTI), a coalition of mayors focused on resilience and adaptation programs. Last week, mayors of the ten states along the river met with leaders from the global and North American insurance industry to discuss reducing vulnerabilities and building resilience in the face of climate-related disasters.

To further its goals to strengthen the global economy, China has already invested $300 billion of its pledged $1 trillion towards its Belt and Road Initiative—a massive infrastructure investment plan that spans 60 countries across Southeast Asia, Central Asia, Africa, South Asia, the Middle East, and Eastern Europe. China’s initiative will shift the world’s political, environmental, and economic landscape.
