Governments are legally bound to ensure the right to food for all. Nevertheless, today there are one billion hungry people in the world and millions more are food insecure. The 2009 World Summit on Food Security offers a unique opportunity to develop a system of global food security governance that bridges the divide between the conflicting visions and interests of global political, financial, and technical mechanisms. In particular, world leaders should ensure the active participation of governments and civil society organisations representing the poorest and most vulnerable people. At the Summit, world leaders must stop acting in narrow national and corporate interests, and start acting in the interests of international food security, peace, and stability.
