1. Limited supply of fresh water
Only one percent of water on earth is fresh water that is readily available for human consumption. this fresh water which is stored in rivers, streams and lakes is called surface water. Somer fresh water can also be found deep underground and is known as groundwater.
2. Uneven distribution of fresh water
Example: canada has 20 percent of the worlds fresh water supply whereas, india has only 10 percent.This situation is made worse by the fact that india's population is 30 times that of canada.
These are some of the reasons for water constraint.
