A Global Water Ledger Built On the Blockchain

Water is critical for all human activity and in light of climate change,  a careful handling of water is more vital than ever. A Block chain  allows us to do this. 

Advantages

• Infrastructure already in place for highly developed areas, IE water meters. 
• Points to areas of use with a high degree of accuracy.
• Refines data on our ecological needs.
• Able to forecast future water requirements.

Challenges

• Areas with non-metered water or areas lacking required infrastructure for water metering

Incentives  could be given on basis of conservation or locating inefficiencies  within the system. As this is operating on a peer to peer network,  voting could be done far more effectively for both funding improvements  and potential crisis's could be closely monitored.
