The world is facing a water crisis of unprecedented proportions, and it's high time we take notice. From Puerto Rico's water crisis to the shrinking Colorado River, from toxic chemicals in English water bodies to the bombing of desalination plants in the Middle East, the signs are everywhere. The worst El Niño in recorded history is unfolding in the Pacific, affecting weather and water around the world, and violence over water is worsening. Communities are mobilizing to block water-hungry datacenters, concerned that their water resources will be drained away.
This isn't just a natural consequence of climate variability; it's the direct result of accelerating human-caused climate changes, decades of neglect, and underinvestment in our water institutions and infrastructure. Climate scientists have been warning us for years about the consequences of our actions, but their warnings were ignored, dismissed, and downplayed. And now, we're reaping the consequences.
Politicians continue to prevaricate, refusing to take action to protect water resources, or worse, rolling back earlier efforts. The Trump administration's EPA has halted efforts to regulate new water pollutants and weakened regulations put in place by previous administrations. And the administration has continued to push for billions of dollars of cuts to federal agencies that coordinate research on water resources and climate.
If governments continue to fail to address the water and climate crises, the coming decades will inevitably see worsening water-related violence and conflict and deteriorating public and ecological health. But it doesn't have to be this way.
People care deeply about water, and we know what needs to be done. No new technology needs to be invented to provide safe water and sanitation to the billions of people who still lack it. The cost of providing water to all and cleaning up the consequences of unregulated and uncontrolled water pollution is far less than the costs of failing to do so.
Violence over shared water resources can be lessened by international agreements and diplomacy over shared watersheds. Smart investments in water efficiency technologies and regulations and in advanced wastewater treatment systems can improve the resilience of existing water infrastructure to extreme events. Far more food can be grown with far less water with efficient irrigation systems, reducing pressures on overtapped aquifers and rivers.
The rapid expansion of renewable energy systems and the rapid phase-out of fossil fuels will both slow the rate of climate change and reduce the amount of water required to produce the energy we all require – a win-win. But we need more public education about both water threats and solutions, more bipartisan actions by our politicians, and more investment by governments, corporations, and communities in the technologies and policies that we know work but are failing to pursue with the urgency the growing crises demand.
The world is waking up to the water crisis, and it's high time we take action. We can't afford to ignore the signs any longer. It's time to act, and act now.
