C.A.P -The Common Agricultural Policy is a system of European Union agricultural subsidies and programmes. It represents 48% of the EU´s budget, €49.8 billion in 2006 (up from €48.5 billion in 2005).
The CAP combines a direct subsidy payment for crops and land which may be cultivated with price support mechanisms, including guaranteed minimum prices, import tariffs and quotas on certain goods from outside the EU. Reforms of the system are currently underway reducing import controls and transferring subsidy to land stewardship rather than specific crop production (phased from 2004 to 2012). Detailed implementation of the scheme varies in different member countries of the EU.

GM Food-Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering, using a process of either Cisgenesis or Transgenesis. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding (plant breeding and animal breeding), and somaclonal variation.

Green revolution- Green Revolution refers to the transformation of agriculture that began in 1945, largely due to the life work One significant factor in this revolution was the Mexican government's request to establish an agricultural research station to develop more varieties of wheat that could be used to feed the rapidly growing population of the country.
