Comments from the Community


  1. Noel Wilson says:

    Health target is questionable. Sure head loading isn’t wild but ergonomic implications of 20kg sloshing packs arent either. This statement obviously comes from Grief and should say so?

  2. Noel Wilson says:

    Does it have emergency relief as a target user?

  3. Noel Wilson says:

    Distribution statement may need some elaboration to explain the math.

  4. Craig A. Atkinson says:

    CTI Ewing Ginder: Target region is Sub-saharan Africa? Or is there a “global” data option?

  5. Craig A. Atkinson says:

    Target region for the CTI Ewing Grinder: there is no specific target country per the individual product report, but Subsaharan Africa could be listed as the target region in the comparison view (as this is where the website says they are meant to have impact).

  6. Craig A. Atkinson says:

    Wouldn’t the energy requirement be “human power”?
