The Exigibilidade study is an advocacy tool which provides practical examples on how to implement the right to food at country level. The study underlines the very important role of the civil society in creating mechanisms to make the state accountable for violations of the right to adequate food. In Brazil, important institutional advances towards the development of instruments to claim, investigate and monitor the realization of the right to food have been set up. This document aims at present ing those innovative mechanisms, so that the civil society and governments in other countries can benefit from these experiences.
