Water is a basic human need. Yet, across the globe, it is a tool of control and conflict. Whether it is used as a bargaining chip among nations or a source of internal tension, water has shifted from being a resource to a way to gain leverage.

Weaponizing Water

According to the Pacific Institute, there have been 62 acts of water weaponization since 2020 alone, more than the entire previous decade combined. In Gaza, the situation is dire. Humanitarian groups have reported that Israeli authorities have completely restricted aid and contaminated water systems, deepening a preexisting humanitarian crisis. This is the deliberate weaponization of water in conflict, which may qualify as a war crime. In Ukraine, both Russian and Ukrainian forces have attacked dams and water pipelines in acts of hydraulic warfare that disrupt civilian life and energy infrastructure. These actions reflect a growing trend in which water systems are involved in acts of war.

Beyond war zones, water is also at the center of growing geopolitical tension. In South Asia, India and Pakistan are locked in a water crisis over the Indus River. India’s recent suspension of the 1960 Indus Waters Treaty has raised fears of agricultural collapse in Pakistan. In East Africa, communities surrounding Lake Turkana are clashing violently over water access, with Ethiopia’s Omo River development fueling deadly competition.

Crisis Close to Home

Even in the United States, water is becoming a national crisis. The Colorado River, which supplies 40 million people, has seen a 20 percent decline in flow over the past century. Projections estimate an additional 31 percent drop by 2050. Due to relentless overpumping over 28 million acre feet of groundwater have disappeared since 2000. States are now engaged in tense negotiations to revise outdated compacts and reduce water use. Arizona alone is set to cut 760,000 acre feet of water from its allocation this year. California and Nevada will also face significant reductions. These cuts are difficult to implement and are already stirring major legal and political disputes.

Enough Isn’t Enough

Some argue that describing water as a “weapon” overstates the problem. They point to long standing disputes over rivers and aquifers, emphasizing that water sharing and negotiation are nothing new. Others highlight that treaties, like the Indus Waters Treaty, or regional compacts prove that international cooperation is still possible.

While not unfounded, these arguments miss the urgency of today’s situation. Climate change, population growth and failing infrastructure have increased the stakes. What used to be a distant concern is now accelerating quickly, and the consequences are already playing out across multiple regions. Existing treaties are under strain, and new conflicts are emerging faster than institutions can respond.

The Solution

To move forward, we need a new framework for addressing water as a critical global issue. First, water must be treated as a central geopolitical concern. Clear enforcement mechanisms should strengthen international agreements, not just symbolic commitments. Countries must also invest in equitable infrastructure, particularly for marginalized communities. In the American West, for instance, many Indigenous tribes were left out of the original Colorado River compact and still struggle for basic water access.

Moreover, targeting war zones’ water infrastructure is considered a war crime under international law, but that status should be enforced by holding groups and people accountable. Additionally, mechanisms for rapid repair and humanitarian response must be developed and enforced by global institutions. Simultaneously, local resilience should be prioritized. Communities need the tools and funding to build drought-resistant systems, adopt water-efficient technologies and ensure food security without depleting resources.

If the world is to survive the coming climate challenges, water must be treated with the seriousness and care it demands. Water is essential to life, so manipulating its access ultimately endangers life itself.
