|The [[w:Green Revolution|Green Revolution]] and the events after that made India self-sufficient in [[w:food security|food security]]. Thanks to the new tools provided by science and technologies our annual grain produce is scaling new highs every year. Since the Green Revolution, new [[w:rice|rice]] varieties have been introduced in Indian fields which are slowly replacing the traditionally grown rice varieties. Year after year, high yielding rice varieties are being preferred over the traditional native verities in our fields. During [[w:Vedic civilization|Vedic period]] approximately 4,00,000 varieties of rice existed in India, many of them still exist in India{{fact}}. Some unconfirmed reports suggest that out of so many varieties consumption of rice in India is limited to about just 10 varieties{{fact}}.

This uncontrolled and unplanned expansion of a few high yielding rice varieties will eventually lead to drastic reduction in biodiversity of food grains in our fields. Loss of [[biodiversity]] can have its own far fetching impact on our food security. Our country’s food grain biodiversity is becoming more and more susceptible to pathogen attacks. For example, in the 1970s when [[w:rice grassy stunt virus|rice grassy stunt virus]] infected rice fields of India, 6,273 varieties of Indian rice were tested for their sensitivity to this virus. Only one Indian variety that was ''[[w:Oryza nivara|Oryza nivara]]'', growing near [[w:Gonda|Gonda]], in [[Uttar Pradesh]] <ref name="Gonda">[http://blog.krya.in/2011/03/ruminations-on-rice/ Ruminations on rice] Accessed: Feb 10, 2012</ref> was found to be resistant to this virus, which was later used to make hybrid resistant varieties which are in propagation now <ref name="Wiki">[http://en.wikipedia.org/wiki/Biodiversity Wikipedia article on Biodiversity] Accessed: Feb 10, 2012</ref><ref name="Agri">[http://agritech.tnau.ac.in/environment/envi_index%20-%20biodiversity-human%20benefits.html Benefits of biodiversity] Accessed: Feb 10, 2012</ref>. Examples of other agricultural disasters are [[w:Irish potato famine|Irish potato famine]] in 1842 – 1845 and [[w:Coffee rust attack|Coffee rust attack]] in 1970. Irish potato famine was caused disease potato blight and it wiping out 25% of [[Ireland|Ireland’s]] population. Coffee rust whipped out the coffee plantations in Sri Lanka, Brazil, and Central America <ref name=Gonda/><ref name="Agri/>. Collapse of European wine industry in 19th century and US Southern Corn Leaf Blight epidemic of 1970 were the result of loss of agricultural biodiversity<ref name=Wiki/>.
Preference of high yielding varieties is leading our fields to [[w:monoculture|monoculture]] which can be a major contributing factor to such agricultural disasters, threatening our food security.
