Problems caused due to water scarcity

Answer 1

Health
In many developing countries, people are forced to drink low quality water from flowing streams, many of which are contaminated. There are many water-borne disease that 
people die of. 
Hunger
It takes a lot of water to grow food and care for animals. Experts say that globally we use 70% of our water sources for agriculture and irrigation, and only 10% on domestic uses.
Education
It is a bit hard to see how water and education is related. For many people in other parts of the world children (and teen girls) have to be up at dawn to collect water for the family.
Poverty
Access to quality water is key to economic prosperity and better living standards. Businesses and schools thrive when people come to work on time and not have to spend all morning looking for water. Restaurants, hotels and shopping places need to keep clean to attract tourists and foreign investments.
The effects of water scarcity can be grouped into these 4 broad areas— Health, Hunger, Education and Poverty.
