Water shortage is a serious global problem that impacts populations in several ways. Over 1 billion people lack access to safe drinking water, especially in less developed countries where 1 in 5 people do not have reliable access. Water shortage can result from irregular supply, drought, and high agricultural usage. It leads to domestic water rationing, reduced agricultural yields and food shortages. It also increases industrial costs and prices when fresh water becomes more scarce and expensive. Countries sharing river sources can experience political conflicts over water access and dam construction that disrupts downstream supply.

- 1. Chong Boon Secondary Geography Department Sec 1 Geography Unit 4 Lesson 5 Impact of water shortage
- 2. Thinking questions •What are the problems associated with water shortage?
- 3. Lesson Objectives • In this lesson, you will –Describe the problems that water shortage brings.
- 4. Water shortage is a serious problem • Water is the most essential resource. • Humans cannot survive without water. • When faced with irregular supply, water rationing is implemented.
- 5. Domestic Impact of shortage • 1.1 billion people globally lack access to safe drinking water. • In LDCs, one in five people do not have access to safe water. • Agricultural use and droughts create the shortage.
- 6. Water Rationing • Making water available only certain times of the day. • Occurred in the 1960s in Singapore.
- 7. Economic impact • Reduced Agricultural Yields – Decreased water supply leads to crop failure. – Less food produced lead to starvation. • Increased industrial costs – Fresh water is vital to production by industries. – Water prices increase due to shortage leading to increase in price of products.
- 8. Political Impact • Conflict over water supply –Countries that share a river source (river) –Construction of dams lead to reduction of water supply downstream. –Increase demands upstream lead to conflict.
- 10. Summary Are you now able to • Describe the problems that water shortage brings?
