The global water and sanitation crisis is not a new story. Each World Water Day, we review the sobering statistics with which we are becoming all too familiar: the expected 40 percent gap in global water supply and demand by 2050.

The billions of additional dollars still needed to finance water infrastructure. The 4.5 billion people who lack access to safely managed sanitation services.

The fact that water crises have ranked among the top global risks in terms of potential impact seven years in a row. (GreenBiz editor’s note: The “revolution” encompasses breakthroughs in artificial intelligence, robotics, the Internet of Things, autonomous vehicles, 3-D printing, nanotechnology, biotechnology, materials science, energy storage and quantum computing.) It will also be important to establish the right governance frameworks and policies, societal engagement and acceptance, and investment landscapes and financing models.

Here are five examples of how the 4IR could help make water insecurity a thing of the past: By providing a secure, transparent and distributed ledger to record transactions between parties, blockchain-based technology fundamentally could transform the way water resources are managed and traded. First and foremost, harnessing this capability could enable everyone from households, industry consumers, water managers and policymakers to access the same data on water quality and quantity and make more informed decisions.

Such transparency would help inform consumer decisions around when to conserve or use water. In turn, it could help prevent corrupt behavior in situations where there may be an incentive for local authorities to tamper with or withhold water quality data. Read more from greenbiz.com…
