Soil and Food security How it is possible to meet this growing food demand ? Should people eat less food ?????? Or Should people fight for hunger???

1. Food security is one of the
great global challenges of the
21st century
That will require solutions on
the time scale of only a few
decades

2. However,The resources to feed this
growing population are limited

3. In 1960,
one hectare of land produced
enough food to feed two
people;
By 2050,
the same amount of land will
need to feed more than six
people

7. Soil and Food Security

8. What does “food security” mean?
Food security is a situation that exists
when all people, at all times, have
sufficient, safe and nutritious food that
meets their dietary needs and food
preferences for an active and healthy
life.

9. we want to shed a little light on how
SOIL is waging war against hunger– not
by collecting canned goods or
distributing meals
Butbymaking itpossible for people to
grow more food

12. How Is Soil Running Out?
Farmland is being lost at an accelerating rate
due to erosion, desertification, salinisation, and
desertification.
Soil erosion as big problem as global warming,
say scientists
Each year more than 10m hectares of crop land
are degraded or lost by erosion, though more
than 99% of the world's food comes from the soil

13. How Is Soil Running Out?
Soil erosion threatens to leave Earth hungry
Food security may depend critically on finite
sources of nutrients which are expected to run
short in the mid-century as world demand for food
explodes.
Central to this problems is excessive nutrient
mining

14. How Is Soil Running Out?
A significant problem is human misuse of the
soil which has led to pollution or contamination.
Most of these problems relate to increased
industrialization where much pollution going
unchecked, leading to severe land degradation.
Misuse of soil in this way threatens the ability
of soils to meet reasonable safety standards and
has jeopardized food production.

15. Plan Build Test Evaluate
Why haven’t we heard more about
Soil?
Probably the living soil isn’t that sexy
 Even people don’t think about how soil
connected with so many other things:
 Including health, environment, climate,
water and most importantly with food
security.

20. SINS OF HUMANITY CONTINUED….

21.  Soil and Crops are Like a Mother and her child
 If a Soil (Like Mother) give so many crops
(children) and do not get any
management(care) ,Soil (mother) will be lost of
nutrient and degraded (sick)
 At the same time, she will lose her capacity
to give birth as Soil loss its fertility
Fertile soil doesn't fall from the sky ,so it
needs management
Soil Versus Crops

22. People will be relying on the
soil to provide food and
ultimately for their survival.
This means that we need to look
after our soils to ensure that
they can support this growing
population.

23. NOT TAKING SOILS FOR GRANTED

24. NOT TAKING SOILS FOR GRANTED
 Humanity will suffer even with great
scientific strides.
 Political stability and global
peace are threatened because of soil
degradation, food insecurity, and
desperateness.
The time to act is now.

25. The soil is the great connector of
our lives, the source, and destination
of it all
 I have a dream that one day we
will live in a world where progress will
not be judged by the production
yields, but by the color and Carbon
content of the soils
