Global Water Scarcity
The world faces a water scarcity crisis.
That’s a bold statement that seems simple enough, but what do we really mean when we say that? Well, when we talk about global water scarcity, at least for the next few paragraphs, we’re referring to three main points.
- Water use is increasing , while the global water supply remains fixed.
- Water is not distributed to everyone who needs it .
- Population growth means more food, which means more agriculture, which means more water. To give us an idea of how much more food, by 2050, agriculture will need to feed about 2.6 billion more people than are alive today .
Until now, when we’ve needed more food, we’ve grown more of it on more land, using groundwater and dams to irrigate . Unfortunately, neither of those plans will work much longer . We’re using groundwater faster than it naturally replaces itself, and pulling that much water from the ground actually causes the land to sink  and pollutes whatever water is leftover . We’ve also dammed most places that can be dammed . So, population growth, along with our limited ability to make more water sources, means that we need to use water much better than we do right now. WaterBit helps farmers do just that.
One step towards getting more out of our land is through precision irrigation, where we give plants exactly the amount of water they need. By providing plants with just the right amount of water, you can improve plant health, reduce operating costs, and practice environmental stewardship, which we’ll discuss in the next post. If we start implementing solutions now, we can secure agricultural production over the next 35 years and beyond.
