Question

what are the main reasons for water scarecity in these days​

Answer 1

Water scarcity, both natural and of human origin, is the lack of sufficient available water resources to meet the demands within a region. Water is unequally distributed over time and space. Much of it is wasted, polluted and unsustainably managed.

There is no global water scarcity as such, but a number of places and regions are chronically short of water because its use at the global level has increased more than twice as fast as the population over the last century.

Pressure on water resources is increasing in several parts of the world, especially in China, India, Pakistan, in the Middle East and many countries and regions of Africa.

1. depletion of ground water
2. anthropogenic global warming
3. irregular patterns of climate

5. deforestation
