Who should provide food, and through what relationships? Whose livelihoods should be protected? For over 20 years the peasant farmers of La Via Campesina have been engaged in the fight against injustice, hunger and poverty under the banner of food sovereignty, 'the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems'. They campaign for healthy, sustainable alternatives to an industrial food system controlled by agribusiness companies and the architects of unfair trade agreements. This book draws on grounded case studies of agrarian movements in the Americas and Europe as exemplars of a 'power shift,' as local opposition scales up to global action in an effort to wrest control of our food away from transnational corporations and back to communities.
