Firstly, I agree that food security is critical for not only countries in Africa but also for all countries in the world. Food security today is a global security issue. Stopping the debate over what works and what does not, will not solve the problem of food security but may exacerbate it due to incorrect interventions. Evaluation and the "academic debate" can be used in a variety of ways. For instance: •to help make resource allocation decisions •to help rethink the causes of a problem •to support decision making on competing or best alternatives •to build consensus on the causes of a problem and how to respond. I also agree MVP is doing fantastic work (I spent 3 months in a MV3) but at the same time I am curious to know whether the model should be scaled up? If so how? And for that you need evaluation/debate.
