Hello students, in this video we are going to study about problems of water usage in arid and semi -arid lands and the first one is water scarcity.
00:13
Arid and semi -arid lands receive very little rainfall and the water resources are very limited.
00:27
The demand for water is high due to the growing population and agriculture and also industries.
00:51
As a result, water scarcity is a major problem in the arid and semi -arid regions.
01:03
And the next problem is water quality.
01:10
The limited water resources in the arid and semi -arid lands are often contaminated with pollutants such as salts, minerals and chemicals.
01:42
This makes the water unsuitable for human consumption and irrigation.
01:59
And the next one is water loss.
02:02
Water loss due to the high temperature and low humidity in arid and semi -arid lands, water evaporates very quickly.
02:26
That is, the process of evaporation is very high.
02:35
This leads to water loss from reservoirs, canals and irrigation systems.
02:47
And the next problem is water conflict...
