GRAIN is an international non-governmental organization based in Barcelona, Spain, which works toward sustainable agriculture. It was formed upon the realization that the genetic diversity of the world's food crops has been drastically eliminated. Very few breeds of crop plants are in use today; this is because many have stopped being used in favor of the most robust and productive strains. This is termed genetic erosion. GRAIN's goal is to preserve the diversity of plants used for food and fiber by human beings. GRAIN is generally in opposition of genetically modified organisms.

Cereal crops or grains are mostly grasses cultivated for their edible grains or seeds (i.e., botanically a type of fruit called a caryopsis). Cereal grains are grown in greater quantities and provide more energy worldwide than any other type of crop; they are therefore staple crops. They are also a rich source of carbohydrate. In some developing nations, grain constitutes practically the entire diet of poor people. In developed nations, cereal consumption is more moderate but still substantial.
