Dear members of the HLPE team,
This is a zero draft of the document, nevertheless it already gives a quite comprehensive overview of issues. I feel this zero draft is promising but would benefit from a more "systemic" view.
I have read quite a few of the comments and since I don't want to repeat others I keep my comment very brief:
The team is still working on a categorisation of food systems. This work may benefit from a report that was published by UNSCN earlier this year: "Investments for healthy food systems", available at: unscn.org. The UNSCN paper about "impact measurements of food systems policies" may also proof useful for the project team. This paper is also available at unscn.org
Related to chapter 4: This chapter would need a strong link to the categorisation of food systems. What is currently lacking in chapter 4 is the analysis of how the examples relate with, fit or don't fit in a certain food system. At this moment the cases and examples are reported on at project level, or programme level at most, without any relation to the entire food system. Not all examples are relevant to all food systems and the question the chapter would need to answer is which examples are capable of tipping food system(s) in such a way that the renewed food system delivers healthy and systainable diets to all people at all times. A related question that needs answering is how much critical mass ( provided through the examples and cases in chapter 4) is needed to create that tipping point.
Related to the level of "simplicity"of the report: I believe the authors need to take care not to mistake valuechains for food systems. These are two very distinct concepts, where a valuechain can at most be a ( small) part of a food system.
I am looking forward reading a next version of the report.
