Water sustains life on our planet. And access to clean and safe water is foundational to society. So why has it only been in recent years that water has risen to the top of discussions of climate and security? Richard W. Spinrad, the Under Secretary of Commerce for Oceans and Atmosphere and NOAA Administrator, says that one of the biggest reasons is the major impact that climate-related changes in precipitation like droughts and extreme rainfall are having across the globe: “We’re starting to see things like we’ve never seen before. The nature of storms is changing: We saw five feet of rain fall in Hurricane Harvey. Five feet.”

China’s high-speed railway (HSR) is the most recent poster child for the country’s rapid development, with more HSR tracks than the rest of the world combined. Since 2004, the Chinese government has invested more than 10 trillion RMB to build a 40,000-kilometer (km) network of trains that zip between stations at speeds reaching 350 km/hr (or 220 miles per hour). Not to be outdone, by 2035 the government aims to expand this train network by 75 percent to help the country reach its transport connectivity and low-carbon transportation goals. 

The world has plenty of reasons to avoid conflict already. Yet attendees at the recently-concluded COP27 climate conference in Sharm el-Sheikh, Egypt were presented with another compelling argument: Warfare is bad for global warming. So much so, in fact, that Ukraine’s delegation to the conference organized a special session at the conference of parties on “War Related Emissions,” bringing along a tree trunk bearing scars from Russian shell fragments as tangible evidence.

Egypt’s Gebel Elba National Park is, by all accounts, a spectacular place. But it better be to justify the fuss it takes to visit. First you have to apply for a permit. If that’s approved (and almost none have been in recent years), you need to travel with an approved tour operator. Even then, you must be accompanied by police at all times.

Earlier in 2022, Ecuador’s capital was left “virtually paralyzed” after some 14,000 people, mainly Indigenous Ecuadorians, participated in 17 days of sometimes violent nationwide protests. The actions forced the Lasso government to the negotiating table for a 90-day dialogue with Indigenous leaders. By early September, the parties signed a temporary moratorium on the development of oil blocks and the allocation of new mining contracts.

The Klamath River Dam removal, slated for early 2024, is a significant milestone in the journey towards bringing back healthy rivers in the United States. This action will restore nearly 300 miles of river habitat in the Klamath and its tributaries across Southern Oregon and Northern California, allowing salmon, a critical source of economic and nutritional value for the local communities, to return. As the world’s largest dam removal and river restoration project in history, this project will have lasting impacts on the health of this river and represents an opportunity for building momentum to continue global river protection and restoration.

Is water important in climate policy? It seems obvious. Water has a well-established link as the medium of most negative climate impacts. Yet when it comes to addressing the climate crisis, the answer depends very much on who you ask.

As climate change is increasingly recognized as a security issue, a parallel understanding is also developing. Traditional categories and approaches may not be the optimal way to address the threats posed by climate impacts.

The nation states and international institutions at the center of security discussions now are shifting their approach. For instance, the U.S. has affirmed and moved to institutionalize its commitment to address the national security implications of climate change under the Biden Administration. In doing so, it is joining an increasing number of other nation-states (the UK, France, Sweden, Germany and New Zealand) that have also developed institutional arrangements and plans for their national response to climate insecurity.
