Impacts of modern agriculture
Status of Organic Farming-World
What is Organic Farming?
Organic farming is the

livestock without the use of
synthetic chemicals and in-
Organic agriculture aims at
the human welfare without
any harm to the environment
which is the foundation of
human life itself.
History of Organic Farming
Organic farming was practiced in India since
thousands of years. Agriculture was practiced
using organic techniques, where the fertilizers,
pesticides, etc., were obtained from plant and
Post-independent India witnessed severe food

What is Organic agriculture
Organic agriculture is a production
system that sustains the health of
soil, ecosystem and people.
It relies on ecological processes,
biodiversity and biological cycles
adapted to local conditions, rather
than the use of synthetic inputs
with adverse effects.
Organic agriculture combines
tradition, innovation and science
to benefit the environment and
promote fair relationships and a
good quality life for all involved.
Healthy food: Contains no toxic substances
„Natural & Good taste
„Higher benefit cost ratio due to less external
input use and premium price (20-25%)

Why farm organically?
Organic farming aims to:
increase long-term soil fertility.

ensure that water stays clean and safe.
use resources which the farmer already has,
so the farmer needs less money to buy farm
produce nutritious food, feed for animals and
high quality crops to sell at a good price.
What is conventional/ modern
Modern agriculture uses pesticides,
herbicides, fungicides, rodenticides and
harmful chemicals to produce the food we
The food produced from conventional
agriculture is harmful to human health
because they contain residues of chemicals
and in-organic fertilizers.
Intensive Farming - chemicals
Many different chemicals are used to
make plants and animals grow faster
Intensive farmers use artificial fertilizers
and growth promoters.
It is easier to use than manure and smaller
quantities are needed, because it contains
more of the elements.
Artificial fertilizers are spread on the
ground or sprayed on the crops.
Intensive Farming - chemicals
They do not just disappear but stay in the plants that we eat,
so our food is contaminated with chemicals.
Soil used to grow the plants will also be contaminated and
have chemicals in it for a very long time.
Animals eat the grass , which has had
chemicals sprayed on to it, so the chemicals
get into their blood and therefore the meat
that we eat.
Chemicals run off the land into rivers
and kill plants and fish.
Artificial fertilizers are banned in Organic farming.
Organic farmers use animal manure, compost and human sewage,
(which has been heated to destroy any harmful microbes) to make their
‘Green manure’ is grown – plants are grown,
then ploughed in and left to rot.
Worms, insects and bacteria underground are
always working on making the soil good.
By using a process called CROP ROTATION
(changing the crop grown each year), the farmer
can keep a good soil for many years.

A 22-year farming trial in N York (USA)
Organic farming produces the same yields of
corn and soybeans as does conventional
farming, but uses 30 percent less energy, less
water and no pesticides,
"Organic farming approaches for these crops not only use an
average of 30 percent less fossil energy but also conserve
more water in the soil, induce less erosion, maintain soil quality
and conserve more biological resources than conventional
What is wrong with intensive
Artificial fertilisers and herbicides are easily washed from the soil
and pollute rivers, lakes and water courses.
The prolonged use of artificial fertilisers results in soils with a low
organic matter content which is easily eroded by wind and rain.
Dependency on fertilisers. Greater amounts are needed every
year to produce the same yields of crops.
Artificial pesticides can stay in the soil for a long time and enter
the food chain where they build up in the bodies of animals and
humans, causing health problems.
Artificial chemicals destroy soil micro-organisms resulting in poor
soil structure and aeration and decreasing nutrient availability.
Pests and diseases become more difficult to control as they
become resistant to artificial pesticides. The numbers of natural
enemies decrease because of pesticide use and habitat loss.
How 'modern farming' affects our world
• Land exhaustion – Loss of soil fertility
• Nitrate run-off – water contamination
• Soil erosion
• Reduced soil porosity due to soil compaction
• Excessive use of pesticides, weedi cides, fungicides
• Cruelty to animals due to over-crowding
• Loss of cultivated biodiversity
• Threat to indigenous seeds and animal breeds and species
• Habitat destruction
• Contaminated food
• Destruction of traditional knowledge systems and traditions
• Control of agriculture inputs and food distribution channel
• Threat to individual farmers

“Intensive cultivation of land without conservation of soil fertility and soil
structure would lead ultimately to the springing up of deserts. Irrigation
without arrangements for drainage would result in soils getting alkaline or
saline. Indiscriminate use of pesticides, fungicides and herbicides could
cause adverse changes in biological balance as well as lead to an increase
in the incidence of cancer and other diseases, through the toxic residues
present in the grains or other edible parts. Unscientific tapping of
underground water would lead to the rapid exhaustion of this wonderful
capital resource left to us through ages of natural farming. The rapid
replacement of numerous locally adapted varieties with one or two high
yielding strains in large contiguous areas would result in the spread of serious
diseases capable of wiping out entire crops, as happened prior to the Irish
potato famine of 1845 and the Bengal rice famine of 1942. Therefore, the
initiation of exploitative agriculture without a proper understanding of the
various consequences of every one of the changes introduced into traditional
agriculture and without first building up a proper scientific and training base
to sustain it, may only lead us into an era of agricultural disaster in the long
run, rather than to an era of agricultural prosperity.”

◦ use of well adapted breeds,
◦ conserve animal genetic resource biodiversity
◦ access to pastures
◦ No growth hormones
◦ No animal by-products in feed
◦ Loose and comfortable
