Can you imagine a day without water? It’s hard to understand, isn’t it? You need at least some water throughout the day, for drinking, cooking or washing dishes. Here’s a fact that may surprise you. On average, we need about 50 to 100 liters of water per day for basic health and hygiene worldwide. However, if we’re talking about living a life with proper nutrition and consumption, this number goes up to 4,000 liters per person per day.

Water is everywhere – in the oceans, in the air, in the soil, all interconnected in this complex hydrological cycle. But we humans are ruining it. The Global Commission on Water Economics (GCEW) has identified this as a growing problem. Now there are two things you need to know about: blue water and green water footprint. Blue water is the water we use for farming and industry, in rivers, lakes and groundwater. Then there’s green water, the water from precipitation stored in the soil, consumed by plants through transpiration and evaporation.

Guess what? This green water provides almost half of the precipitation on land. But here’s the thing. The green water cycle is under great threat. The biggest reason is deforestation. When we cut down trees, less water is released into the atmosphere, which means less rain. This isn’t just a local problem. Moisture from forests can travel thousands of miles, so deforestation in one part of the world can actually reduce rainfall in another part of the world. When we cut down vast forests for agriculture or urban expansion, we disrupt the entire flow of the water cycle.

The problem doesn’t end there. Rapid urbanization makes the problem worse. More cities means more concrete, less land, and less green water. So this not only disrupts local rainfall patterns, but also prevents groundwater from replenishing. Add in pollution and we have a real problem. Experts say there is a serious decline in what they call total water storage—the total amount of water in rivers, soil, underground reservoirs, and even ice.

The Result?

Floods in some places, droughts in others. This water crisis dilemma highlights a serious imbalance affecting nearly 3 billion people. In fact, more than half of the world’s food production is currently located in regions facing worsening water scarcity, including densely populated areas like southern Europe, northeastern China, and northwest India, and this could spread everywhere.

By 2050, the ongoing impact of changing rainfall patterns, rising temperatures, and declining water storage, exacerbated by deforestation, could have significant economic consequences. To put things in perspective, high-income countries could see their GDP shrink by an average of 8%, while low-income countries could see even bigger declines of 10% to 15%.

So what’s the solution, you may ask?

The GCEW proposes restoring ecosystems, protecting forests, increasing water-saving technologies, and adopting smarter farming practices to rebalance the water cycle. One fascinating solution to this end is atmospheric water generators (AWGs). Now, these aren’t futuristic devices. Simply put, AWGs literally pull water from the air. It draws moisture from the atmosphere by cooling humid air to its dew point, causing water vapor to condense. This condensed water is then filtered and purified, meeting World Health Organization (WHO) standards for drinking water, and best of all, it works best in areas with high humidity, such as coastal areas. For example, on the Navajo Nation in Arizona, an AWG system produces up to 200 gallons (more than 750 liters) of clean water per day, helping a community that has long struggled with water access.

AWGs have also been installed around parks and beaches in Abu Dhabi so visitors can enjoy quality drinking water on the go. Pretty cool, right? But AWGs aren’t just a flashy solution for cities. They can be a lifeline for communities in crisis. Take disaster-prone areas, for example. When natural disasters strike, traditional water supply lines are often disrupted, leaving people without access to clean water. In such scenarios, AWGs could provide a quick solution. Because they can be solar-powered, these machines can be deployed to remote areas and ensure that people still have a steady source of water when all else fails.

This isn’t just for villages. AWGs can make factories water-neutral by reducing their reliance on groundwater. But like everything else, AWGs come with a catch. They’re not cheap. A medium-sized commercial unit can cost you $30,000 to $50,000. But that’s where public-private partnerships come in. Governments don’t have to foot the bill alone. Companies can chip in. So whether it’s disaster relief, greener industries, or providing clean water to rural areas, AWGs can be a game-changer. All we need is the will to make them widespread. There’s hope. But we need to act before it’s too late.
