It has become crucial to defend seeds. In the past 20 or 30 years, what was once seen as normal – peasant farmers growing, selecting, saving and exchanging seeds – has come under attack from corporations seeking to control and commodify the very basis of agriculture. This was the subject of the session at the World Social Forum in Tunis on Peasant Seeds jointly organized on March 28, 2013 by La Vía Campesina, GRAIN and the ETC Group. There are four pillars of agriculture, says Nandini Jairam, a member of La Vía Campesina and a peasant farmer from Karnataka, India, “these are soil, water, seeds, and peasants.”
