it reveals green revolution, it's elements,advantages and limitations of green revolution

2. As the American revolution and
industrial revolution, there
occurred a new revolution in the
20th century, that dramatically
changed the field of agriculture,
and this revolution is known as
the green revolution

3. Green revolution was
a period when the
productivity of global
agriculture increased
drastically as a result
of new advances,
which results in high
productivity
Synthetic herbicides
and pesticides
Chemical fertilizers

4. HISTORY OF GREEN REVOLUTION
Norman Borlaug
He was the first to
found the green
revolution. He
conducted a research
in Mexico in 1940 and
developed a high yield
varieties of wheat
In 1965 the Indira
Gandhi govt. took a
major step in
agriculture. Dr.
M.S.Swaminathan,
father of green
revolution led this
revolution as a project

5. ELEMENTS OF GREEN
REVOLUTION
Expansion of farming
areas
Green revolution continued with
quantitative expansion of farmlands
Artificial monsoon
There had to be two monsoons per
year, one would be the natural
monsoon and the other an artificial
monsoon
Multiple cropping
Instead of growing a single crop per
year, the field should use to grow
two or more crop through out the
year
High yield crops
Specially designed crop is developed
to produce more overall yield

6. High yielding
varieties of
seed
Chemical
fertilizers
Modern
agricultural
machinery
Advanced
irrigational
technology
Rural
electrification
Soil testing
and soil
conservation

7. ADVANTAGES OF
GREEN REVOLUTION

8. It It made it possible
to grow more crops
on roughly the same
amount of land with
a similar amount of
effort

9. The farmers of
rural areas learned
new techniques for
building irrigation
systems to bring
water to their fields

10. Developing countries
become self
sufficient in food
grains and hence
resulted in decreased
poverty level

11. India transformed
itself from a
starving nation to
an exporter of
food

12. The crop yield
is increased
three times
than the earlier

13. It boosted industrial
growth, created job
opportunities and
improved the
quality of life of the
people

14. It created plenty of job
not only for agricultural
workers but also
industrial workers by
the creation of
factories and hydro
electric powers

15. It has changed the
attitude of people
towards
agricultural work as
now it has wide
scope

16.  It increases the greenery of
environment
 It brings rain in proper time
 It reduces the pollution level
 It minimizes the effect of global
warming
 It minimizes the effect of soil
erosion
 Floods can be controlled to
some extent
Some other advantages
on environment

17. Limitations of
green revolution

18. Even if the green revolution is
impressive, it was not 100%success
the poorer farmers can not achieve yield as high as those
with better access to water, fertilizer and land
Lead to
reduction in the
organic matter in
the soil
A few states
showed best
result in green
revolution
New hybrids
required use of
chemical
fertilizers and
pesticides
The new farming
techniques, has
caused pollution
of natural
resources
Un employment
among un
educated
farmers
