Clean Water Scarcity - Population Growth
Population growth is contributing to clean water scarcity on the planet, generally by increasing the demand for a limited supply of water.
- Growth in population causes excessive consumption of resources. The growth in population in the world has tripled and water consumption has grown six-fold.
- Inequality in wealth distribution has also brought waste. Currently, 20% of the poorest countries make up 1.3% of private consumption, while 20% of the richest countries contribute to 86%.
- For example, the estimated use of water by a family of four in the US is 400 gallons of water per day with a 70% indoor use, with 27% of this use happening in the bathroom.
- The usage of water globally has doubled since 1960. Today, 1.7 billion people live in countries that use 80% of their water supply every year on agriculture, industries and cities.
- About 70% of water is used for irrigation and agriculture to feed the high population.
- Over 44 countries in the world are experiencing high stress water levels, while 17 countries are experiencing extreme stress water levels.
- In 2050, 9.7 billion people will live in water stress regions.
- Approximately 844 million people around the globe do not have access to clean water and safe water.
- Four billion people live in regions with severe water scarcity for at least a month annually.
- Water demand will grow to 55% by 2050, with 70% of the water being used for irrigation.
- Over 80% of Middle East's and North Africa's water is not reused. Therefore, they should create a new water source by recycling waste water.
- Australia was not able to cut their domestic water use by nearly half. By this example, it is recommended to implement effective water management.
- Another solution may be improving efficiency in agriculture.
- It is recommended to use satellites to create a water budget, which can help to measure how much water is available and how much is coming in from rivers and other sources.
- Ensuring a fair distribution of water across the globe, is another way to combat this issue.
