3. By 2025, 800
million people will
experience absolute
water scarcity, &
two- thirds of the
world population
could
be under stress
conditions.1.1 billion people have
no
access to any type of
improved
drinking source of water.

4. • At the start of the 21st century
un- clean water is the world’s
second biggest killer of
children.
• 1.6

5. World Water Day, on 22 March every
year, is about focusing attention on the
importance of water. This year’s theme,
‘Nature for Water’, explores nature-
based solutions to the water challenges

6. NATURE BASED SOLUTIONS
Restoring forests, grasslands and natural
wetlands……
Reconnecting rivers to floodplains, creating
buffers of vegetation along water courses ……..
– these are all examples of NBS that help the
management of water availability and quality.

7. Most NBS, including in urban landscapes,
essentially involve the management of vegetation,
soils and/or wetlands, including rivers and lakes.
NBS are not a panacea to the critical water-related
challenges we face as the global population grows,
but they can provide innovative and cost-effective
options for supplementing insufficient or ageing
water infrastructure.

8. RAIN WATER HARVESTING
• It is a technique of collection and storage
of rainwater into natural reservoirs or
tanks, or the infiltration of surface water
into subsurface aquifers (before it is lost
as surface runoff).
• One method of rainwater harvesting is
rooftop harvesting
• Uses include water for gardens, livestock,
and irrigation, etc.

9. The reasons for using rainwater harvesting
systems answer three questions:
•What: Rainwater harvesting will improve
water supply, food production, and ultimately
food security.
•Who: Water insecure households or
individuals in rural areas will benefit the most
from rainwater harvesting systems.
•How: Since rainwater harvesting leads to
water supply which leads to food security,
this will greatly contribute to income
generation.

12. Water Conservation Tips for Indoors
• Let your parents know about
leaks in your house
– Leaks are easily fixable and
save you water and money
• Tell your parents about high-
efficiency washers, faucets, and
toilets
• Run your dishwasher or
washing machine only with full
loads
• Turn off the faucet when
brushing or shaving
• Take shorter showers

13. Water Conservation Tips for Outside
• Water your lawn only when
it needs it
• Water your plants earlier in
the day when less can
evaporate
• Plant plants and shrubs that
use less water, like
sunflowers, lavender, and
marigolds
• Don’t water the gutter
• Don’t run the hose while
washing your car

14. Water Conservation Tips for School
• Bring or use a reusable
water bottle like a Nalgene
instead of the drinking
fountain
• Turn off the tap while
washing your hands
• Pay attention to water
conservation signs in
bathrooms and drinking
fountains
• Inform administration if
there are any leaking pipes,
hoses, or hydrants
