In recent decades, the international system has undergone profound changes—especially in terms of the types of threats that destabilize international peace and security. As new threats emerge, a focus on new dimensions of the concept of security is now reaching the top of the international agenda. In this context, the global freshwater crisis is beginning to be perceived as an existential threat to states requiring extraordinary measures to alleviate or solve the problem.

Waters that cross international political borders can drive the countries that share them to conflict—or encourage cooperation between them. Indeed, since the 1940s, overall trends point to a tendency for countries to cooperate over shared water resources, which stands in stark contrast to media portrayals of “water wars.”

Yet instances of conflict over water have increased slightly since 2000. Why? Most of them are fueled by water quantity disputes or the unilateral development of dams or other infrastructure. Institutions often play a key role in facilitating cooperation (and reducing conflict) over shared waters, but their growth and adoption have slowed over the last two to three decades.

At a recent Wilson Center event on the shifting geopolitics of critical minerals, Cory Combs, Associate Director at Beijing-based Trivium China, noted that “the nature of global resource competition is changing—and quite rapidly.”

By 2050, two-thirds of the population will face some form of water stress. As a fundamental part of life, water—or a lack of it—influences other parts of life, including conflict. In fact, as author Marcus King notes in his new book, Weaponizing Water: Water Stress and Islamic Extremist Violence in Africa and the Middle East, there is a “correlation between the spheres of influence of violent extremist organizations (VEOs) and the driest lands or areas of sparse vegetation in some of the most arid regions on earth.”

Green hydrogen is often portrayed as a key component in the green energy transition, since it is produced with renewable energy through electrolysis – the splitting up of freshwater into hydrogen and oxygen – and it does not emit carbon dioxide when combusted. Yet green hydrogen’s huge potential for the decarbonization of hard-to-abate sectors (e.g. steelmaking and production of fertilizers) as well as maritime shipping and aviation are not the only promises that it harbors. Green hydrogen’s use as an energy storage solution makes it particularly promising for remote and sparsely populated areas with an abundance of renewable energy resources such as the Norwegian Arctic.

Soil degradation affects one-third of the Earth’s surface, triggering dust storms, floods, and landslides. It is also a global threat to our food supply, and diminishes the soil’s ability to sequester carbon to mitigate climate change. China has only 0.21 hectares of agricultural land per person, which is well below the global average. Worse yet, over 40 percent of that land is already degraded.
