essay on scarcity of water in the world in 300words​

Answer 1

Water Scarcity:

Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.

As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. Inadequate sanitation is also a problem for 2.4 billion people—they are exposed to diseases, such as cholera and typhoid fever, and other water-borne illnesses. Two million people, mostly children, die each year from diarrheal diseases alone.

Many of the water systems that keep ecosystems thriving and feed a growing human population have become stressed. Rivers, lakes and aquifers are drying up or becoming too polluted to use. More than half the world’s wetlands have disappeared. Agriculture consumes more water than any other source and wastes much of that through inefficiencies. Climate change is altering patterns of weather and water around the world, causing shortages and droughts in some areas and floods in others.

At the current consumption rate, this situation will only get worse. By 2025, two-thirds of the world’s population may face water shortages. And ecosystems around the world will suffer even more.

Explanation:

water scarcity in world

Water is life because plants and animals cannot live without water. Water is needed to ensure food security, feed livestock, take up industrial production and to conserve the biodiversity and environment. Although, India is not a water poor country, due to growing human population, severe neglect and over-exploitation of this resource, water is becoming a scarce commodity. While this is a growing concern all over the world, India is most vulnerable because of the growing demand and in-disciplined lifestyle. This calls for immediate attention by the stakeholders to make sustainable use of the available water resources to ensure better quality of lives.

Importance of water

vers of water usage

The demand for water in India is steeply increasing because of the following reasons (Amarasinghe, et al. 2007):

The primary reason is population as India’s population which was 1.3 billion in 2005 is expected to rise to 1.66 billion in 2050.

There is also going to be a major impact on development in the form of urbanisation. In 2007, 28.2% of the Indian population was living in urban areas and the urban population is expected to increase to 55.2% by 2050.

The per capita income of Indians will increase from $468 in 2007 to $6735 in 2050.

Increased industrialisation will demand more water as its contribution to GDP will increase from 29.1% in 2000 to 40% by 2050. Thus, the demand for water will increase from 30 billion m3 in 2000 to 161 billion m3 in 2050.

The agriculture development will be more on water intensive cash crops and there will be 80% increase in the demand for water
