Some of the contributing factors to water scarcity are climate change, water overuse, and increased pollution. Many areas around the globe are affected by this phenomenon, and about 2.7 billion people experience water scarcity each and every year.

What are the causes of water shortage How should the natural resources be preserved and utilized?

Overuse in agriculture is a major source of freshwater shortage as it reduces the amount of water available for other purposes. Agricultural overuse also adds to pollution, as the runoff from fields and farms carries pollutants like fertilizers and pesticides into nearby rivers, lakes, and streams.

What are the problems of water availability?

Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region’s demand.

How does climate change threaten to alter the world’s water supplies?

Warmer air can hold more moisture than cool air. As a result, in a warmer world, the air will suck up more water from oceans, lakes, soil and plants. The drier conditions this air leaves behind could negatively affect drinking water supplies and agriculture.

Why is water not available everywhere?

Then again, water isn’t available everywhere: across space, there are deserts and swamps; over time, seasons of rain and years of drought. Also, a water crisis isn’t about how much water there is – a desert isn’t water-stressed if no one is using the water; it’s just an arid place.

What Will water be like in the future?

By 2020 about 30-40% of the world will have water scarcity, and according to the researchers, climate change can make this even worse. With only 7% of the world’s freshwater, China plans to produce 807 million gallons a day from desalination by 2020, roughly quadruple the country’s current capacity.

How does population affect water availability?
