Plenty of Water – just not in the right places
Limited supplies of fresh water
- About 97% of the worlds water is tied up in the oceans and seas
- Only about 3% is fresh and about of that 70% is frozen
- Of the remaining 30%, the majority is underground in aquifers leaving a small fraction in lakes, rivers and in the atmosphere
- Much of the water in rivers is held in remote parts of the world (i.e. the amazon)
- The amount of water in the atmosphere is far greater than the amount of water in rivers
- Accessing this atmospheric water by increasing rainfall in a targeted way is a critical element in attempts to increase the usable supply of fresh water
