GM crops
According to WHO
• “Genetically modified (GM) crops are crops derived from organisms whose genetic material (DNA) has
been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism”
OR• Genetically modified crops are plants used in
agriculture, the DNA of which has been modified using genetic engineering techniques.
GM crops are described by many different names
Genetically Engineering Crops(GE)Transgenic or Biotech CropsGenetically Modified Organism(GMO)

How GM crops helps in Long term food and Nutritional security
Food and Nutrition Security
According to UNSCN:“Food and nutrition security exists when all
people at all times have physical, social and economic access to food, which is consumed in sufficient quantity and quality to meet their dietary needs and food preferences, and is supported by an environment of adequate sanitation, health services and care, allowing for a healthy and active life.”
Why we need food & Nutritional security
• To cope situation like
Hunger remains the No.1 causes of dead in the world
42% of world under nourished children live in India -Global hunger
Index 2010Over 20 crore will sleep
hungry tonightOver 25 lakh Indians die of
hunger every year.
How GM crops help in food and Nutritional security
• yield Increases

GM crops are
Virus Tolerance-e.g. Hawaiian papaya
Herbicides Tolerances-63%GM are HT
Insect Resistances
Drought ResistantGm Crops requires less
water for their growth hence are capable to sustain in drought condition.
Useful in areas which receive less rainfall
Stress tolerance– salt-tolerant crops .– Frost resistant crops.– Flood resistant crops.– Development of crops that make more efficient use of nitrogen and other nutrients.
GM Crops enhances the Nutritional security Enhanced vitamins (e.g. higher levels of beta carotene the
precursor of Vitamin A and E). Enhanced minerals (e.g. higher levels of iron) Enhanced healthy fatty acids content (e.g. omega 3
unsaturated fatty acids). Enhanced amino acid (e.g. tryptophan) Enhanced protein (e.g. in potatoes). Enhanced lipids content Enhanced carbohydrates content Enhanced levels of antioxidants to help fight cancer. Reduced risk of allergic reactions (e.g. by silencing or
removing genes in food such as wheat and peanuts).
Food shelf life increases
Spoiling of food decreasesThus shelf life of food increasese.g.GM tomatoes

GM Crops- beneficial to farmers
Farmers benefit generally from GM Crops
Spend less money on pesticides, insecticides
Crops are strongerMore profit from GM Crops
Role of Government
subsidies to farmer for growing GM crops
Making and implementing different policy related to GM crops
Setting of testing Labs for Testing GM foods Passage of BRAI Bill with
suggested amendments
Conclusion Its better to eat GM foods Rather then dying hungrily
THANK YOU
