Water is the driver of Nature.

2. Water covers 70.9% of
the Earth's surface, and is vital for all known forms
of life. On Earth, 96.5% of the planet's water is found
in oceans, 1.7% in groundwater, 1.7% in glaciers and
the ice caps of Antarctica and Greenland, a small
fraction in other large water bodies, and 0.001% in
the air as vapor, clouds (formed of solid and liquid
water particles suspended in air), and precipitation.
Only 2.5% of the Earth's water is
freshwater, and 98.8% of that water is in ice and
groundwater. Less than 0.3% of all freshwater is in
rivers, lakes, and the atmosphere, and an even smaller
amount of the Earth's freshwater (0.003%) is contained
within biological bodies and manufactured products.

3. Water is
a chemical substance with
the chemical formula H2O.
A water molecule contains
one oxygen and
two hydrogen atoms
connected
by covalent bonds. Water is
a liquid at ambient
conditions, but it often co-
exists on Earth with
its solid state, ice, and
gaseous state (water
vapor or steam).

4. Water is life
Virtually everything we do or use each day involves
water. Yet, we do not give it the importance that is
due to it. India will soon be a water-stressed country
and we all need to work towards our water security.
Simple actions can be adopted to reduce the wastage
of water and use it wisely.

5. India is gifted with a rich and vast diversity of
natural resources, water being one of them.
Its development and management plays a vital
role in agriculture production. Integrated
water management is vital for poverty
reduction, environmental sustenance and
sustainable economic development. National
Water Policy (2002) envisages that the water
resources of the country should be developed
and managed in an integrated manner.

6. Water resources are divisible into two
distinct categories :
1. The surface-water resources.
2. The under ground-water
resources

7.  Water pollution occurs when a body of
water is adversely affected due to the
addition of large amounts of materials
to the water. The sources of water
pollution are categorized as being a
point source or a non-source point of
pollution. Point sources of pollution
occur when the polluting substance is
emitted directly into the waterway. A
pipe spewing toxic chemicals directly
into a river is an example. A non-point
source occurs when there is runoff of
pollutants into a waterway, for instance
when fertilizer from a field is carried
into a stream by surface runoff.

 Organic Substances.
 Ecological Pollution
 Thermal Pollution

10. 
Water
conservation refers to
reducing the usage of
water and recycling
of waste water for
different purposes
such as cleaning
, manufacturing ,and
agricultural irrigation

12.  Reduce personal water costs
 Minimize the need for local governments to
fund expensive reservoir, water treatment
plant and pipeline projects
 Help maintain sufficient water in streams,
rivers and lakes for fishing, boating,
swimming, protection of aquatic life and
downstream users.

13.  Increase the crop water use
efficiency
 Improve irrigation application
efficiency
 Increase capture and utilization of
precipitation
 Increase irrigation water diversion
and delivery efficiencies
 Reduce water use through adoption
of conservation measures and new
technologies for water management
