Book excerpt: The Right to Food Guidelines provide practical guidance on ways to implement the right to adequate food in a wide range of policy and programmes areas through a human rights-based approach. Since the adoption of the Right to Food Guidelines, FAO and its partners have produced a wealth of tools, strengthened capacity, and facilitated multi-stakeholder dialogues worldwide. But the goal of realizing the right to food of everyone is not accomplished yet- over 820 million people are currently suffering from chronic hunger. This fifteen-Year Retrospective on the Right to Food Guidelines helps us look back and understand what has worked and why, where the bottlenecks lie, and how governments and their partners can be most effective in the fight against hunger and malnutrition.
