What is Nanotechnology ?
• Manipulating materials and systems at the scale of atoms and molecules
• ‘Nano’ = size scale between 1nm and 100nm.• A nanometer (nm) is one-billionth of a meter• Eg: Atom = 0.1nm
Virus = 75-100nm Bacteria = 1,000=10,000nm
• Richard Feynman, a well-known American physicist
– “What would happen if we could arrange the atoms one by one the way we want them?”
Who’s involved in nanotechnology?
• Kraft• Nestle• Unilever• Pepsi Co.• BASF• Syngenta• Over 60 governments world-wide
Nanotechnology in Agriculture
• How to feed the growing population by producing more on a shrinking landscape ; Lesser input costs & Lesser hazards to the eco-system?
• How to add to the income of agricultural producers so as to sustain their motivation to grow crops?
• How to make the transaction in agro products smooth, safe and reliable?
• Applications of nanotechnology have the potential to change the entire agriculture sector and food industry chain from production to conservation, processing, packaging, transportation, and even waste treatment.
Major Challenges in Agriculture & Food Industry
Wastage of inputs
Large uncultivable
areas
Food security for growing
numbers
Low productivity in
cultivable areas
Wastage of products
Skill limitations
What Nanotechnology offers for Agriculture?
• Food security for growing numbers
Revolutionize the sector with new tools for disease detection, targeted treatment, enhancing the ability of plants to absorb
nutrients, fight diseases and withstand environmental pressures and effective systems for processing, storage and
packaging
• Low productivity in cultivable areas
Precision farming makes farming more targeted and scientific Accurate information through applications of
nanotechnology for real time monitoring of soil conditions, environmental changes and diseases and plant health issues
• Large uncultivable areas
Bringing more areas under cultivation by Nanotechnology enabled environmental monitoring and management including cost effective water management through applications of nano science
change the land use pattern substantially
• Wastage of inputs
Enabled sensors and smart delivery systems will help the agricultural industry combat viruses and other crop pathogens
• Wastage of products
Precision farming through use of nanotechnology applications can also help to reduce agricultural waste and thus keep environmental pollution to a minimum
• Skill limitations
Nanotechnology applications have the potential to produce easy-to-handle devices which reduce the dependence on human skills on many fronts, thus reducing the human risk
