How Geopolitical Tensions over Transboundary Aquifers Affect Water Diplomacy

Quick fact

More than 600 transboundary aquifers exist worldwide, yet fewer than ten have any formal agreement for how they should be shared—a striking lack of international governance compared to rivers.

Why this is interesting

You know rivers can spark conflict, but what if the water is invisible—buried beneath two countries? Transboundary aquifers hold 97% of the world's freshwater, yet they are the least governed water source on Earth.
